In this new volume in the Oxford Psychology Series, the author presents a highly readable account of the cognitive unconscious, focusing in particular on the problem of implicit learning. Implicit learning is defined as the acquisition of knowledge that takes place independently of the conscious attempts to learn and largely in the absence of explicit knowledge about what was acquired. One of the core assumptions of this argument is that implicit learning is a fundamental, "root" process, one (...) that lies at the very heart of the adaptive behavioral repertoire of every complex organism. The author's goals are to outline the essential features of implicit learning that have emerged from the many studies that have been carried out in a variety of experimental laboratories over the past several decades; to present the various alternative perspectives on this issue that have been proposed by other researchers and to try to accommodate these views with his own; to structure the literature so that it can be seen in the context of standard heuristics of evolutionary biology; to present the material within a functionalist approach and to try to show why the experimental data should be seen as entailing particular epistemological perspectives; and to present implicit processing as encompassing a general and ubiquitous set of operations that have wide currency and several possible applications. Chapter 1 begins with the core problem under consideration in this book, a characterization of "implicit learning" as it has come to be used in the literature. Reber puts this seemingly specialized topic into a general framework and suggests a theoretical model based on standard heuristics of evolutionary biology. In his account, Reber weaves a capsule history of interest in and work on the cognitive unconscious. Chapter 2 turns to a detailed overview of the experimental work on the acquisition of implicit knowledge, which currently is of great interest. Chapter 3 develops the evolutionary model within which one can see learning and cognition as richly intertwining issues and not as two distinct fields with one dominating the other. Finally, Chapter 4 explores a variety of entailments and speculations concerning implicit cognitive processes and their general role in the larger scope of human performance. (shrink)
The overwhelming majority of those who theorize about implicit biases posit that these biases are caused by some sort of association. However, what exactly this claim amounts to is rarely specified. In this paper, I distinguish between understandings of association as a theory of learning, a theory of cognitive structure, a theory of mental processes, and as an implementation base for cognition. I then argue that the crucial senses of association for elucidating implicit bias are the cognitive structure (...) and mental process senses. A hypothesis is subsequently derived: if associations really underpin implicit biases, then implicit biases should be modulated by counterconditioning or extinction but should not be modulated by rational argumentation. This hypothesis is false; implicit biases are not, at heart, predicated on any associative structures or associative processes but instead arise because of unconscious propositionally structured beliefs. I conclude by discussing how the case study of implicit bias illuminates problems with popular dual process models of cognitive architecture. (shrink)
I offer an account of the relation between explanations of behaviour in terms of psychological states and explanations in terms of neural states that: makes it transparent how they can be true together; explains why explanations in terms of psychological states are characteristically of behaviour described in general and relational terms, and explains why certain sorts of neurological investigations undermine psychological explanations of behaviour, while others leave them intact. In the course of the argument, I offer an account of (...) class='Hi'>implicit theories. (shrink)
In Boghossian's 1997 paper, 'Analyticity' he presented an account of a prioriknowledge of basic logical principles as available by inference from knowledge of their role in determining the meaning of the logical constants by implicit definitiontogether with knowledge of the meanings so-determined that we possess through ourprivileged access to meaning. Some commentators (e.g. BonJour (1998), Glüer (2003),Jenkins (2008)) have objected that if the thesis of implicit definition on which he relieswere true, knowledge of the meaning of the constants (...) would presuppose knowledge of the very logical principles knowledge of which the account purports to explain. Aconsequence would seem to be that implicit definition is incompatible with privilegedaccess. I argue that whilst it is possible for Boghossian to defend against theseobjections the form of argument he proposes does exhibit a subtle form of questionbegging such that it exhibits a transmission of warrant-failure.

Implicit Learning and Consciousness challenges conventional wisdom and presents the most up-to-date studies to define, quantify and test the predictions of the main models of implicit learning. The chapters include a variety of research from computer modeling, experimental psychology and neural imaging to the clinical data resulting from work with amnesics. The result is a topical book that provides an overview of the debate on implicit learning, and the various philosophical, psychological and neurological frameworks in which it (...) can be placed. It will be of interest to undergraduates, postgraduates and the philosophical, psychological and modeling research community. (shrink)
How do we find out whether someone is conscious of some information or not? A simple answer is “We just ask them”! However, things are not so simple. Here, we review recent developments in the use of subjective and objective methods in implicit learning research and discuss the highly complex methodological problems that their use raises in the domain.
I show that words with indefinite implicit complements occasion a dilemma for their model theory. There has been only two previous attempts to address this problem, one by Fodor and Fodor (1980) and one by Dowty (1981). Each requires that any word tolerating an implicit complement be treated as ambiguous between two different lexical entries and that a meaning postulate or lexical rule be given to constrain suitably the meanings of the various entries for the word. I show (...) that the positing of such an ambiguity runs counter to the facts and propose an alternative solution which does not appeal to ambiguity, meaning postulates or lexical rules. Indeed, I show that the dilemma posed by indefinite implicit complements is posed by all implicit complements and that a general solution to the problem of implicit complements follows from an independently motivated, single treatment of five other problems, that of subcategorization, that of phrasal projections of words, that of defining a model theoretic structure for phrase structure grammars, that of complement polyvalence and that of complement polyadicity.

This squib aims to show that the acceptability status of sluicing examples with an implicit antecedent in islands varies and discusses what is responsible for this variability. After investigating two representative structural approaches to sluicing that posit unpronounced structure in ellipsis sites, namely, Chung et al.’s (Nat Lang Semant 3:239–282, 1995; in Mikkelsen et al. (eds) Representing language: Essays in honor of Judith Aissen, 2010) LF-recovery analysis and Merchant’s (The syntax of silence: Sluicing, islands, and identity in ellipsis. Oxford: (...) Oxford University Press 2001) PF-deletion analysis, we demonstrate that the acceptability data presented are challenging for both of them. Acceptable sluicing examples with implicit correlates in islands cast doubt on Chung, Ladusaw, and McCloskey’s strict locality requirement, while unacceptable or degraded sluicing examples necessitate additional constraints for Merchant, who employs E-type anaphora as an escape hatch for island violations in sluicing. The gradient nature of the acceptability status of the examples under discussion calls for a non-structural factor that controls their acceptability. We speculate that it is discourse activation of implicit correlates that plays this crucial role. (shrink)
Background: The development of implicit tests for measuring biases and behavioral predispositions is a recent development within psychology. While such tests are usually researched within a social-cognitive paradigm, behavioral researchers have also begun to view these tests as potential tests of conditioning histories, including in the sexual domain. Objective: The objective of this paper is to illustrate the utility of a behavioral approach to implicit testing and means by which implicit tests can be built to the standards (...) of behavioral psychologists. Design: Research findings illustrating the short history of implicit testing within the experimental analysis of behavior are reviewed. Relevant parallel and overlapping research findings from the field of social cognition and on the Implicit Association Test are also outlined. Results: New preliminary data obtained with both normal and sex offender populations are described in order to illustrate how behavior-analytically conceived implicit tests may have potential as investigative tools for assessing histories of sexual arousal conditioning and derived stimulus associations. Conclusion: It is concluded that popular implicit tests are likely sensitive to conditioned and derived stimulus associations in the history of the test-taker rather than ‘unconscious cognitions’, per se. Keywords: implicit association test; function acquisition speed test; relational frame theory; stimulus equivalence; sex offenders; sexual interests (Published: 15 March 2012) Citation: Socioaffective Neuroscience & Psychology 2012, 2 : 17335 - DOI: 10.3402/snp.v2i0.17335.

Holding content explicitly requires a form of self knowledge. But what does the relevant self knowledge look like? Using theory of mind as an example, this paper argues that the correct answer to this question will have to take into account the crucial role of language based deliberation, but warns against the standard assumption that explicitness is necessary for ascribing awareness. It argues in line with Bayne that intentional action is at least an equally valid criterion for awareness. This leads (...) to a distinction between different levels of implicitness. Postulating these different levels, it is argued, allows us to make better sense of the empirical literature on early false belief task abilities. (shrink)
The degree to which information is encoded explicitly in a representation is related to the computational cost of recovering or using the information. Knowledge that is implicit in a system need not be represented at all, even implicitly, if the cost of recovering it is prohibitive.
While the study of implicit learning is nothing new, the field as a whole has come to embody — over the last decade or so — ongoing questioning about three of the most fundamental debates in the cognitive sciences: The nature of consciousness, the nature of mental representation (in particular the difficult issue of abstraction), and the role of experience in shaping the cognitive system. Our main goal in this chapter is to offer a framework that attempts to integrate (...) current thinking about these three issues in a way that specifically links consciousness with adaptation and learning. Our assumptions about this relationship are rooted in further assumptions about the nature of processing and of representation in cognitive systems. When considered together, we believe that these assumptions offer a new perspective on the relationships between conscious and unconscious processing and on the function of consciousness in cognitive systems.

Over the past decade, sequence learning has gradually become a central paradigm through which to study implicit learning. In this chapter, we start by briefly summarizing the results obtained with different variants of the sequence learning paradigm. We distinguish three subparadigms in terms of whether the stimulus material is generated either by following a fixed and repeating sequence (e.g., Nissen & Bullemer, 1987), by relying on a complex set of rules from which one can produce several alternative deterministic sequences (...) (e.g., Lewicki, Hill & Bizot, 1988; Stadler, 1989), or by following the output of a probabilistic set of rules such as instantiated by noisy finite-state grammars (Cleeremans & McClelland, 1991; Jiménez, Mendéz & Cleeremans, 1996). Next, we focus on the processes involved in sequence representation and acquisition. We suggest that the sensitivity to the sequential structure observed in the probabilistic subparadigm can only be a result of the acquisition of a representation of the statistical constraints of the material, and that this sensitivity emerges through the operation of mechanisms that are well instantiated by connectionist models such as the Simple Recurrent Network (Elman, 1990; Cleeremans, 1993b). We present new simulation work meant to explore to what extent the model can also account for specific data obtained in a paradigmatic instance of deterministic, rule-based sequence learning task: Lewicki et al. (1988)'s situation. Finally, we report on the results of an experiment that compares learning on otherwise similar deterministic and probabilistic structures, and we show that learning of both types of structures is equivalent only under conditions that maximally hinder explicit acquisition. Taken together, these simulation and experimental data lend support to the claim that implicit learning in all three sequence learning subparadigms can amount to a form of statistical sequence learning. They also suggest that distinguishing among several theories of sequence representation and acquisition may require us to analize the data in great detail. Hopefully, however, some truth can be found in such details.. (shrink)
Various systems that learn are examined to show how content is carried in connections installed by a learning history. Agents do not explicitly use the content of such states in practical reasoning, yet the content plays an important role in explaining behavior, and the physical state carrying that content plays a role in causing behavior, given other occurrent beliefs and desires. This leads to an understanding of the environmental reasons which are the determinate content of these states, and leads to (...) a better grasp of how representational content can be carried by systems without an explicit representation.

In Making it Explicit, Brandom aims to articulate an account of conceptual content that accommodates its normativity--a requirement on theories of content that Brandom traces to Wittgenstein's rule following considerations. It is widely held that the normativity requirement cannot be met, or at least not with ease, because theories of content face an intractable dilemma. Brandom proposes to evade the dilemma by adopting a middle road--one that uses normative vocabulary, but treats norms as implicit in practices. I argue that (...) this proposal fails to evade the dilemma, as Brandom himself understands it. Despite his use of normative vocabulary, Brandom's theory fares no better than the reductionist theories he criticises. I consider some responses that Brandom might make to my charges, and finally conclude that his proposal founders on his own criteria. (shrink)
Paul Boghossian advocates a version of the analytic theory of a priori knowledge. His defense of an "epistemic" notion of analyticity is based on an implicit definition account ofthe meaning of the logical constants. Boghossian underestimates the power of the classical Quinean criticisms, however; the challenge to substantiate the distinction between empirical and non-empirical sentences, as forcefully presented in Two Dogmas, still stands, and the regress from Truth by Convention still needs to be avoided. Here, Quine also showed that (...) there are no implicit definers for the logical constants. Moreover, even if they existed, their epistemic analyticity would, on Boghossian's own account, be doubtful. (shrink)
The paper argues that the theory of Implicit Definition cannot give an account of knowledge of logical principles. According to this theory, the meanings of certain expressions are determined such that they make certain principles containing them true; this is supposed to explain our knowledge of the principles as derived from our knowledge of what the expressions mean. The paper argues that this explanation succeeds only if Implicit Definition can account for our understanding of the logical constants, and (...) that fully understanding a logical constant in turn requires the ability to apply it correctly in particular cases. It is shown, however, that Implicit Definition cannot account for this ability, even if it draws on introduction rules for the logical constants. In particular, Implicit Definition cannot account for our ability to apply negation in particular cases. Owing to constraints relating to the unique characterisation of logical constants, invoking the notion of rejection does not remedy the situation. Given its failure to explain knowledge of logic, the prospects of Implicit Definition to explain other kinds of a priori knowledge are even worse. (shrink)
We first describe recent empirical research on racial cognition, particularly work on implicit racial biases that suggests they are widespread, that they can coexist with explicitly avowed anti-racist and tolerant attitudes, and that they influence behavior in a variety of subtle but troubling ways. We then consider a cluster of questions that the existence and character of implicit racial biases raise for moral theory. First, is it morally condemnable to harbor an implicit racial bias? Second, ought each (...) of us to suspect ourselves of racial bias, and therefore correct for it in ordinary activity, such as grading student papers? (shrink)
Much of traditional AI exemplifies the explicit representation paradigm, and during the late 1980''s a heated debate arose between the classical and connectionist camps as to whether beliefs and rules receive an explicit or implicit representation in human cognition. In a recent paper, Kirsh (1990) questions the coherence of the fundamental distinction underlying this debate. He argues that our basic intuitions concerning explicit and implicit representations are not only confused but inconsistent. Ultimately, Kirsh proposes a new formulation of (...) the distinction, based upon the criterion ofconstant time processing.The present paper examines Kirsh''s claims. It is argued that Kirsh fails to demonstrate that our usage of explicit and implicit is seriously confused or inconsistent. Furthermore, it is argued that Kirsh''s new formulation of the explicit-implicit distinction is excessively stringent, in that it banishes virtually all sentences of natural language from the realm of explicit representation. By contrast, the present paper proposes definitions for explicit and implicit which preserve most of our strong intuitions concerning straightforward uses of these terms. It is also argued that the distinction delineated here sustains the meaningfulness of the abovementioned debate between classicists and connectionists. (shrink)
In this paper, I take issue with an idea that has emerged from recent relativist proposals, and, in particular, from Lasersohn (Linguistics and Philosophy 28: 643–686, 2005), according to which the correct semantics for taste predicates must use contents that are functions of a judge parameter (in addition to a possible world parameter) rather than implicit arguments lexically associated with such predicates. I argue that the relativist account and the contextualist implicit argument-account are, from the viewpoint of semantics, (...) not much more than notational variants of one another. In other words, given any sentence containing a taste predicate, and given any assignment of values to the relevant parameters, the two accounts predict the same truth value and are, in that sense, equivalent. I also look at possible reasons for preferring one account over the other. The phenomenon of “faultless disagreement” (cf. Kölbel, Truth without objectivity, 2002) is often believed to be one such reason. I argue, against Kölbel and Lasersohn, that disagreement is never faultless: either the two parties genuinely disagree, hence if the one is right then the other is wrong, or the two parties are both right, but their apparent disagreement boils down to a misunderstanding. What is more, even if there were faultless disagreement, I argue that relativism would fail to account for it. The upshot of my paper, then, is to show that there is not much disagreement between a contextualist account that models the judge parameter as an implicit argument to the taste predicate, and a relativist account that models it as a parameter of the circumstances of evaluation. The choice between the two accounts, at least when talking about taste, is thus, to a large extent, a matter of taste. (shrink)
One of the more refractory problems in contemporary discussions of consciousness is the problem of determining what a mental state's being conscious consists in. This paper defends the thesis that a mental state is conscious if and only if it has a certain reflexive character, i.e., if and only if it has a structure that includes an awareness of itself. Since this thesis finds one of its clearest expressions in the work of Brentano, it is his treatment of the thesis (...) on which I initially focus, though I subsequently bring in Sartre where he addresses himself to an important point not considered by Brentano. As part of this investigation, the paper also, more specifically, aims to exhibit as perspicuously as possible the relationship between self-awareness and the phenomenal, or 'what-it- is-like', dimension of conscious experience. I attempt to show, in particular, that the phenomenal character of at least perceptual consciousness can be fully explained in terms of self-awareness, i.e., in terms of a low-level or 'implicit' self-awareness that is built into every conscious perceptual state.

In the scientific study of mind a distinction is drawn between explicit knowledge–knowledge that can be elicited from a subject by suitable inquiry or prompting, can be brought to consciousness, and externally expressed in words–and implicit knowledge–knowledge that cannot be elicited, cannot be made directly conscious, and cannot be articulated. Michael Polanyi (1967) argued that we usually ‘know more than we can say’. The part we can articulate is explicitly known; the part we cannot is implicit.
Three studies investigated implicit brand attitudes and their relation to explicit attitudes, prod- uct usage, and product differentiation. Implicit attitudes were measured using the Implicit As- sociation Test (IAT; Greenwald, McGhee, & Schwartz, 1998). Study 1 showed expected differ- ences in implicit attitudes between users of two leading yogurt brands, also revealing significant correlations between IAT-measured implicit attitudes and explicit attitudes. In Study 2, users of two fast food restaurants (McDonald’s and Milk Bar) showed (...) class='Hi'>implicit attitudi- nal preference for their favorite restaurant. In Study 3, implicit attitudes of users of two soft drinks (Coca-Cola and Pepsi) predicted brand preference, product usage, and brand recognition in a blind taste test. A meta-analytic combination of the three studies showed that the use of IAT measures increased the prediction of behavior relative to explicit attitude measures alone. (shrink)
Running head: Implicit sequence learning ABSTRACT Can we learn without awareness? Although this issue has been extensively explored through studies of implicit learning, there is currently no agreement about the extent to which knowledge can be acquired and projected onto performance in an unconscious way. The controversy, like that surrounding implicit memory, seems to be at least in part attributable to unquestioned acceptance of the unrealistic assumption that tasks are process-pure, that is, that a given task exclusively (...) involves either implicit or explicit knowledge.

When a mental state is conscious â in the sense that there is something it is like for the subject to have it â it instantiates a certain property F in virtue of which it is a conscious state. It is customary to suppose that F is the property of having sensory quality. The paper argues that this supposition is false. The first part of the paper discusses reasons for thinking that unconscious mental states can have a sensory quality, for (...) example in cases of absent-minded perception. If unconscious mental states can have a sensory quality, then sensory quality is an insufficient condition for consciousness. The second part of the paper argues that there are even better reasons to think that sensory quality is an unnecessary condition for consciousness. The idea is that mental states can be conscious even when they lack sensory quality, for example, in the case of certain conscious propositional attitudes. In the third part of the paper, an alternative to the rejected supposition, drawn from the phenomenological tradition, is offered: that consciousness is a matter of implicit self-awareness, rather than of sensory quality. According to this alternative, a mental state is conscious when, and only when, it involves implicit self-awareness. (shrink)

This paper explicates the interaction between the implicit and explicit learning processes in skill acquisition, contrary to the common tendency in the literature of studying each type of learning in isolation. It highlights the interaction between the two types of processes and its various effects on learning, including the synergy effect. This work advocates an integrated model of skill learning that takes into account both implicit and explicit processes; moreover, it embodies a bottom-up approach (first learning implicit (...) knowledge and then explicit knowledge on its basis) towards skill learning. The paper shows that this approach accounts for various effects in the process control task data, in addition to accounting for other data reported elsewhere. (shrink)
Abstract In this paper, I examine the plausibility of Embodied Accounts of Social Cognition by finding fault with the most detailed and convincing version of such an account, as articulated by Daniel Hutto ( 2008 ). I argue that this account fails to offer a plausible ontogeny for folk psychological abilities due to its inability to address recent evidence from implicit false belief tasks that suggest a radically different timeline for the development of these abilities.

What do people learn when they do not know that they are learning? Until recently, all of the work in the area of implicit learning focused on empirical questions and methods. In this book, Axel Cleeremans explores unintentional learning from an information-processing perspective. He introduces a theoretical framework that unifies existing data and models on implicit learning, along with a detailed computational model of human performance in sequence-learning situations.
In this paper I evaluate Michael Dummett’s notion of implicit knowledge by examining his answers to these two questions: (1) Why should we ascribe knowledge of a meaning-theory of a language to a language-user, and why the mode of this knowledge is implicit, but not pure theoretical, pure practical, or unconscious in a Chomskian sense? (2) How could a meaning-theory, which is known implicitly, function as a rule to be followed by the language-user? To answer (1) I shall (...) construct Dummett’s argument for implicit knowledge, which includes three sub-arguments: the argument from rationality, the argument from dilemma, and the argument from communicability. As to (2), I argue that Dummett’s answer confuses knowledge of a meaning-theory with knowledge of a set of grammars. (shrink)
The concept of tacit knowledge is widely used in social sciences to refer to all those knowledge that cannot be codified and have to be transferred by personal contacts. All this literature has been affected by two kind of biases : (1) the interest has been focused more on the result (tacit knowledge) than on the process (implicit learning); (2) tacit knowledge has been somehow reduced to physical skills or know-how; other possible forms of tacit knowledge have been neglected. (...) These two biases seem interconnected one with each other. A greater consideration of the role and relevance of implicit learning allows us to consider tacit knowledge as something more than pure physical skills or know how. This is the first step in order to develop more detailed categorisation of the different forms that tacit knowledge can assume. (shrink)
Recent work in social psychology suggests that people harbor “implicit race biases,” biases which can be unconscious or uncontrollable. Because awareness and control have traditionally been deemed necessary for the ascription of moral responsibility, implicit biases present a unique challenge: do we pardon discrimination based on implicit biases because of its unintentional nature, or do we punish discrimination regardless of how it comes about? The present experiments investigated the impact such theories have upon moral judgments about racial (...) discrimination. The results show that different theories differ in their impact on moral judgments: when implicit biases are defined as unconscious, people hold the biased agent less morally responsible than when these biases are defined as automatic (i.e., difficult to control), or when no theory of implicit bias is provided.

Dienes & Perner propose a theory of implicit and explicit knowledge that is not entirely complete. It does not address many of the empirical issues, nor does it explain the difference between implicit and explicit learning. It does, however, provide a possible unified explanation, as opposed to the more binary theories like the systems and the processing theories of implicit and explicit memory. Furthermore, it is consistent with a theory in which implicit learning is viewed as (...) based on the mechanisms of the cognitive architecture, and explicit learning as strategies that exploit these mechanisms.

The notion of nonconceptual content in Dienes & Perner's theory is examined. A subject may be in a state with nonconceptual content without having the concepts that would be used to describe the state. Nonconceptual content does not seem to be a clear-cut case of either implicit or explicit knowledge. It underlies a kind of practical knowledge, which is not reducible to procedural knowledge, but is accessible to the subject and under voluntary control.
This theoretical integration of social psychology’s main cognitive and affective constructs was shaped by 3 influences: (a) recent widespread interest in automatic and implicit cognition, (b) development of the Implicit Association Test (IAT; A. G. Greenwald, D. E. McGhee, & J. L. K. Schwartz, 1998), and (c) social psychology’s consistency theories of the 1950s, especially F. Heider’s (1958) balance theory. The balanced identity design is introduced as a method to test correlational predictions of the theory. Data obtained with (...) this method revealed that predicted consistency patterns were strongly apparent in the data for implicit (IAT) measures but not in those for parallel explicit (self-report) measures. Two additional not-yet-tested predictions of the theory are described. (shrink)
Implicit learning is the process through which we become sensitive to certain regularities in the environment (1) in the absence of intention to learn about those regularities (2) in the absence of awareness that one is learning, and (3) in such a way that the resulting knowledge is difficult to express.
Abstract The purpose of this paper is to discuss how far it is possible in the present educational system to have an explicit moral education programme.

Yet schools may hope to have some implicit effect by their structure and hidden (...) curriculum. (shrink)
The question of whether or not there is such a thing as "Chinese philosophy" is seldom explicitly raised, but the implicit answers to this question--although different in China and the West--dominate institutional and academic decisions. This article not only constructs a typology to recognize, differentiate, and evaluate various answers to this question, but it also takes the sensitivity of this matter seriously by comparing it with one's attachment to something as sensitive, arbitrary, and meaningless as a family name.

Pila (2009) has criticised the recommendations made by requirements engineers involved in the design of a grid technology for the support of distributed readings of mammograms made by Jirotka et al. (2005). The disagreement between them turns on the notion of “biographical familiarity” and whether it can be a sound basis for trust for the performances of professionals such as radiologists. In the first two sections, this paper gives an interpretation of the position of each side in this disagreement and (...) their recommendation for the design of technology for distributed reading, and in the third the underlying reasons for this is agreement are discussed. It is argued that Pila, in attempting to make room for mistrust as well as trust, brings to the fore the question of having and reflecting upon reasons for trust or mistrust. Pila holds that biographical familiarity is not a sound reason for trust/mistrust, as it seems to obliterate the possibility of mistrust. In response to her proposal, an analysis is proposed of the forms of trust involved in biographical familiarity. In particular, implicit trust is focused upon — as a form of trust in advance of reasons, and as a form of trust contained (in the logical sense) within other reasons. It is proposed that implicit trust has an important role in establishing an intersubjectively shared world in which what counts as a reason for the acceptability of performances such as readings of X-rays is established. Implicit trust, therefore, is necessary for professionals to enter into a “space of reasons”. To insist upon judgements made in the absence of the form of implicit trust at play in biographical familiarity is to demand that radiologists (and other relevantly similar professionals) make judgements regarding whether to trust or mistrust on the basis of reasons capable of being reflected upon, but at the same time leave them without reasons upon which to reflect.

Michael Friedman’s project both historically and systematically testifies to the importance of the relativized a priori. The importance of implicit definitions clearly emerges from Schlick’s General Theory of Knowledge . The main aim of this paper is to show the relationship between both and the relativized a priori through a detailed discussion of Friedman’s work. Succeeding with this will amount to a contribution to recent scholarship showing the importance of Hilbert for Logical Empiricism.
This paper discusses the semantics of bare existentials , i.e. existentials in which nothing follows the post copular NP (e.g. There are four sections ). While it has sometimes been recognized that the interpretation of such sentences depends in some way on context, the exact nature of the context dependence involved has not been properly understood. It is shown that the meaning of bare existentials involves a set-denoting implicit argument, and that the range of interpretations found with bare existentials (...) is predictable from the general properties of implicit arguments. An explicit analysis within a dynamic setting is presented. (shrink)
The goal of this research is to understand the interaction of implicit and explicit psychological processes in dealing with emotional distractions and meta-cognitive control of such distractions. The questions are how emotional and meta-cognitive processes can be separated into implicit and explicit components, and how such a separation can be utilized to improve self-regulation of emotion, which can have significant theoretical and practical implications.

Implicit processes are thought to be relatively fast, inaccessible, holistic, and imprecise, while explicit processes are slow, accessible and precise (e.g., Reber, 1989, Sun 2002). This dichotomy is closely related to some other well-known dichotomies including symbolic versus subsymbolic processing (Rumelhart et al., 1986), conceptual versus subconceptual processing (Smolensky, 1988), and conscious versus unconscious processing (Jacoby et al., 1994). This dichotomy has been justified by extensive studies of implicit and explicit learning, implicit and explicit memory, and (...) class='Hi'>implicit versus explicit metacognition (Reder, 1996).

Implicit learning – broadly construed as learning without awareness – is a complex, multifaceted phenomenon that defies easy definition. Frensch (1998) listed as many as eleven definitions in an overview, a diversity that is undoubtedly symptomatic of the conceptual and methodological challenges that continue to pervade the field forty years after the term first appeared in the literature (Reber, 1967). According to Berry and Dienes (1993), learning is implicit when an individual acquires new information without intending to do (...) so and in such a way that the resulting knowledge is difficult to express. In this, implicit learning thus contrasts strongly with explicit learning (e.g., as when learning how to solve a problem or learning a concept), which is typically hypothesisdriven and fully conscious. Implicit learning is the process through which one becomes sensitive to certain regularities in the environment: (1) without trying to learn regularities, (2) without knowing that one is learning regularities, and (3) in such a way that the resulting knowledge is unconscious.

Electronic Mail: jimenez@usc.es Abstract Stability of activation, while it may be necessary for information to become available to consciousness, is not sufficient to produce phenomenal experience. We suggest that consciousness involves access to information and that access makes information symbolic. From this perspective, implicit representations exist, and are best thought of as sub-symbolic. Crucially, such representations can be causally efficacious in the absence of consciousness.
This article examines the relationship between implicit mental processes and ethical decisions made by managers. Based on the dual-process view in social and cognitive psychology, it is argued that social cognition (e.g., moral judgments) can rely on two different modes of information processing. On one hand, moral judgments reflect explicit, conscious, and extensive cognitive processes, which are attributed to explicit attitude. On the other hand, moral judgments may also be based on implicit, automatic, and effortless processes referring to (...)implicit attitude. To test this thesis, a study involving 182 participants was conducted. The results support the thesis. (shrink)
We present a theoretical account of implicit and explicit learning in terms of ACT-R, an integrated architecture of human cognition as a computational supplement to Dienes & Perner's conceptual analysis of knowledge. Explicit learning is explained in ACT-R by the acquisition of new symbolic knowledge, whereas implicit learning amounts to statistically adjusting subsymbolic quantities associated with that knowledge. We discuss the common foundation of a set of models that are able to explain data gathered in several signature paradigms (...) of implicit learning. (shrink)
In this response, we start from first principles, building up our theory to show more precisely what assumptions we do and do not make about the representational nature of implicit and explicit knowledge (in contrast to the target article, where we started our exposition with a description of a fully fledged representational theory of knowledge (RTK). Along the way, we indicate how our analysis does not rely on linguistic representations but it implies that implicit knowledge is causally efficacious; (...) we discuss the relationship between property structure implicitness and conceptual and nonconceptual content; then we consider the factual, fictional, and functional uses of representations and how we go from there to consciousness. Having shown how the basic theory deals with foundational criticisms, we indicate how the theory can elucidate issues that commentators raised in the particular application areas of explicitation, voluntary control, visual perception, memory, development (with discussion on infancy, theory of mind [TOM] and executive control, gestures), and finally models of learning.

A comprehensive theory of implicit and explicit knowledge must explain phenomenal knowledge (e.g., knowledge regarding one's affective and motivational states), as well as propositional (i.e., “fact”-based) knowledge. Findings from several research areas (i.e., the subliminal mere exposure effect, artificial grammar learning, implicit and self-attributed dependency needs) are used to illustrate the importance of both phenomenal and propositional knowledge for a unified theory of implicit and explicit mental states.
This article explicates the interaction between implicit and explicit processes in skill learning, in contrast to the tendency of researchers to study each type in isolation. It highlights various effects of the interaction on learning (including synergy effects). The authors argue for an integrated model of skill learning that takes into account both implicit and explicit processes. Moreover, they argue for a bottom-up approach (first learning implicit knowledge and then explicit knowledge) in the integrated model. A variety (...) of qualitative data can be accounted for by the approach. A computational model, CLARION, is then used to simulate a range of quantitative data. The results demonstrate the plausibility of the model, which provides a new perspective on skill learning. (shrink)
Implicit knowledge is perhaps better understood as latent knowledge so that it is readily apparent that it contrasts with explicit knowledge in terms of the form of the knowledge representation, rather than by definition in terms of consciousness or awareness. We argue that as a practical matter any definition of the distinction between implicit and explicit knowledge further involves the notion of control.
Dienes and Perner’s theory is not a satisfactory theory of implicit knowledge because by endorsing the representational theory of knowledge, the authors also inadvertently accept that only explicit knowledge can be causally efficacious, and hence that implicit knowledge is an inert category. This conflation between causal efficacy, knowledge, and explicitness is made clear through the authors' strategy, which consists of attributing any observable effect to the existence of representations that are as minimally explicit as needed to account for (...) behavior. In contrast, we believe that causally efficacious and fully implicit knowledge exists, and is best embodied in frameworks that depart radically from classical assumptions. (shrink)
After discussing Robert Almeder’s distinction between explicitly testable scientific explanations and implicitly testable philosophical explanations, I present two criticisms of his position. The first comes in the form of a reductio ad absurdum. Here I show that if we adopt implicit testability as a necessary condition for philosophical explanations, we are forced to concede that many of the subjects that have traditionally been placed under the rubric of philosophy— e.g., ethics, metaphysics, existentialism, phenomenology, and aesthetics—are not really philosophical subjects (...) after all. Nevertheless, because Almeder has a few ways of trying to get around the reductio, I go on to suggest that the distinction between scientific and philosophical explanations is not sufficiently strong enough to provide philosophy with the kind of “robust autonomy” he envisions.

Dienes & Perner's (D&P's) target articles proposes an analysis of explicit knowledge based on a progressive transformation of implicit into explicit products, applying this gradient to different aspects of knowledge that can be represented. The goal is to integrate a philosophical concept of knowledge with relevant psychophysical and neuropsychological data. D&P seem to fill an impressive portion of the gap between these two areas. We focus on two examples where a full synthesis of theoretical and empirical data seems difficult (...) to establish and would require further refinement of the model: action representation and the closely related consciousness of action, which is in turn related to self-consciousness.

Dienes & Perner's target article contains numerous but unsystematic references to the implicit or explicit knowledge of the temporal context of a known state of affairs such as may constitute the content of a propositional attitude. In this commentary, the forms of cognition that, according to D&P, require only implicit knowledge of time are contrasted with those for which explicit temporal knowledge is needed. It is suggested that the explicit representation of time may have been important in human (...) evolution and that certain developmental disorders including autism may be (partly) caused by defective ability to represent time.

The visual system captures a unique contrast between implicit and explicit representation where the same event (location of a visible object) is coded in both ways in parallel. A method of differentiating the two representations is described using an illusion that affects only the explicit representation. Consistent with predictions, implicit information is available only from targets presently visible, but, surprisingly, a two-alternative decision does not disturb the implicit representation.
The focus of this paper is institutional change and the changing role of business in Germany. Back in the 1980s, the German institutional framework was characterized by implicit mandatory and obligatory regulations that set a clear context for responsible corporate behavior. Today, this framework has eroded and given way to a situation in which corporations explicitly and voluntarily take responsibility for social issues. This shift from implicit to explicit corporate social responsibility is an indication of a major institutional (...) change epitomized by the deconstruction of ’old’ and the reconstruction of ‘new’ institutions. In the course of this change, corporations, state actors, and civil society organizations compete for their ideas and interests in what we call a fight for myths. The paper traces this fight for myths and the changing understanding of corporate responsibility in Germany. (shrink)
This commentary discusses how Dienes & Perner's theory of implicit and explicit knowledge applies to memory research. As currently formulated, their theory does seem to account simultaneously for population dissociations and dissociations between conceptual and perceptual priming tasks. In addition, the specification of four distinct memorial states (correlated with different recognition test responses) faces important methodological challenges.
Once Hilbert asserted that the axioms of a theory `define` theprimitive concepts of its language `implicitly''. Thus whensomeone inquires about the meaning of the set-concept, thestandard response reads that axiomatic set-theory defines itimplicitly and that is the end of it. But can we explainthis assertion in a manner that meets minimum standards ofphilosophical scrutiny? Is Jané (2001) wrong when hesays that implicit definability is ``an obscure notion''''? Doesan explanation of it presuppose any particular view on meaning?Is it not a (...) scandal of the philosophy of mathematics that no answersto these questions are around? We submit affirmative answers to allquestions. We argue that a Wittgensteinian conception of meaninglooms large beneath Hilbert''s conception of implicit definability.Within the specific framework of Horwich''s recent Wittgensteiniantheory of meaning called semantic deflationism, we explain anexplicit conception of implicit definability, and then go on toargue that, indeed, set-theory, defines the set-conceptimplicitly according to this conception. We also defend Horwich''sconception against a recent objection from the Neo-Fregeans Hale and Wright (2001). Further, we employ the philosophicalresources gathered to dissolve all traditional worries about thecoherence of the set-concept, raisedby Frege, Russell and Max Black, and whichrecently have been defended vigorously by Hallett (1984) in hismagisterial monograph Cantorian set-theory and limitationof size. Until this day, scandalously, these worries havebeen ignored too by philosophers of mathematics. (shrink)
Dienes & Perner (D&P) argue that nondeclarative knowledge can take multiple forms. We provide empirical support for this from two related lines of research about the development of mathematical reasoning. We then describe how different forms of procedural and declarative knowledge can be effectively modeled in Anderson's ACT-R theory, contrasting this computational approach with D&P's logical approach. The computational approach suggests that the commonly observed developmental progression from more implicit to more explicit knowledge can be viewed as a consequence (...) of accumulating and strengthening mental representations.

The author has elsewhere defended the view that accepting a bribe involves the violation of an implicit or explicit promise or understanding associated with an office or position that one occupies and that therefore it is prima facie wrong to accept a bribe. Michael Philips has criticized this position in a recent paper. He argues that (a) there are cases in which accepting a bribe violates no promises or agreements, and (b) there are cases in which there is no (...) prima facie duty to refuse an offer of a bribe. The author offers replies to both of these objections. (shrink)
In cognitive neuroscience, dissociating the brain networks that ing—has thus become one of the best empirical situations subtend conscious and nonconscious memories constitutes a through which to study the mechanisms of implicit learning, very complex issue, both conceptually and methodologically.
Using explicit memory measures, Cowan predicts a new circumstance in which the central capacity limit of 4 chunks should obtain. Supporting results for such an experiment, using continuous old-new recognition, are described. With implicit memory measures, Cowan assumes that short-term repetition priming reflects the central capacity limit. I argue that this phenomenon instead reflects limits within individual perceptual processing modules.
Dienes & Perner's target article constitutes a significant advance in thinking about implicit knowledge. However, it largely neglects processing details and thus the time scale of mental states realizing propositional attitudes. Considering real-time processing raises questions about the possible brevity of implicit representation, the nature of processes that generate explicit knowledge, and the points of view from which knowledge may be represented. Understanding the propositional attitude analysis in terms of momentary mental states points the way toward answering these (...) questions. (shrink)
Several recent findings support the notion that changes in the environment can be implicitly represented by the visual system. S. R. Mitroff, D. J. Simons, and S. L. Franconeri (2002) challenged this view and proposed alternative interpretations based on explicit strategies. Across 4 experiments, the current study finds no empirical support for such alternative proposals. Experiment 1 shows that subjects do not rely on unchanged items when locating an unaware change. Experiments 2 and 3 show that unaware changes affect performance (...) even when they occur at an unpredictable location. Experiment 4 shows that the unaware congruency effect does not depend simply on the pattern of the final display. The authors point to converging evidence from other methodologies and highlight several weaknesses in Mitroff et al.’s theoretical arguments. It is concluded here that implicit representation of change provides the most parsimonious explanation for both past and present findings. (shrink)
Gesture does not have a fixed position in the Dienes & Perner framework. Its status depends on the way knowledge is expressed. Knowledge reflected in gesture can be fully implicit (neither factuality nor predication is explicit) if the goal is simply to move a pointing hand to a target. Knowledge reflected in gesture can be explicit (both factuality and predication are explicit) if the goal is to indicate an object. However, gesture is not restricted to these two extreme positions. (...) When gestures are unconscious accompaniments to speech and represent information that is distinct from speech, the knowledge they convey is factuality-implicit but predication-explicit.

McFarland and Crouch (2002) reported substantial positive correlations (a) between the Implicit Association Test (IAT) and response speed and (b) between IATs assessing racism or self-esteem and ostensibly unrelated control IATs. Using an IAT measure in millisecond-difference score format, they concluded that the IAT was confounded with general cognitive ability. A reanalysis of these data using the D measure (Greenwald, Nosek, & Banaji, 2003) eliminated the speed of responding confound, although it did not eliminate the correlation between the (...) control and racism IATs. The study was replicated and the two correlations, paralleling those in the original study, emerged for the millisecond-difference score. However, both were reduced to nonsignificance by use of the D measure. These findings are consistent with other recent studies (Mierke & Klauer, 2003) that document the protection afforded by D against cognitive skill confounds. (shrink)
Complex cognitive processes like concept learning involve a mixture of redundant explicit and implicit processes that are active simultaneously. This aspect of cognitive architecture creates difficulties in determining the influence of consciousness on processing. We propose that the interaction between an individual's regulatory focus and the reward structure of the current task influences the degree to which explicit processing is active. Thus, by manipulating people's motivational state and the nature of the task they perform, we can vary the influence (...) of conscious processing in cognitive performance. We demonstrate the utility of this view by focusing on studies in which people acquire new perceptual concepts by learning to classify them. This technique will allow us to better tease apart the roles of explicit and implicit processing in a variety of cognitive tasks. (shrink)
Dienes & Perner present a very interesting analysis of two types of knowledge. It is not clear, however, that the words “implicit” and “explicit” are the best basis on which to build a theory of the two types of knowledge. One is also left uncertain as to whether this theory is the best way of ordering the greatest possible amount of relevant data in a way that yields the simplest account possible.

Stanovich & West's target article undervalues the power of implicit learning (particularly reinforcement learning). Implicit learning may allow the learning of more rational responses–and sometimes even generalisation of knowledge–in contexts where explicit, abstract knowledge proves only of limited value, such as for economic decision-making. Four other comments are made.
In this issue, Pila (2009) has criticised the recommendations made by requirements engineers involved in the design of a grid technology for the support of distributed readings of mammograms made by Jirotka et al. (2005). The disagreement between them turns on the notion of “biographical familiarity” and whether it can be a sound basis for trust for the performances of professionals such as radiologists. In the first two sections, this paper gives an interpretation of the position of each side in (...) this disagreement and their recommendation for the design of technology for distributed reading, and in the third the underlying reasons for this disagreement are discussed. It is argued that Pila, in attempting to make room for mistrust as well as trust, brings to the fore the question of having and reflecting upon reasons for trust or mistrust. Pila holds that biographical familiarity is not a sound reason for trust/mistrust, as it seems to obliterate the possibility of mistrust. In response to her proposal, an analysis is proposed of the forms of trust involved in biographical familiarity. In particular, implicit trust is focused upon—as a form of trust in advance of reasons, and as a form of trust contained (in the logical sense) within other reasons. It is proposed that implicit trust has an important role in establishing an intersubjectively shared world in which what counts as a reason for the acceptability of performances such as readings of X-rays is established. Implicit trust, therefore, is necessary for professionals to enter into a “space of reasons”. To insist upon judgements made in the absence of the form of implicit trust at play in biographical familiarity is to demand that radiologists (and other relevantly similar professionals) make judgements regarding whether to trust or mistrust on the basis of reasons capable of being reflected upon, but at the same time leave them without reasons upon which to reflect.

Male and female participants were instructed to produce an altered response pattern on an Implicit Association Test measure of gender identity by slowing performance in trials requiring the same response to stimuli designating own gender and self. Participants’ faking success was found to be predictable by a measure of slowing relative to unfaked performances. This combined task slowing (CTS) indicator was then applied in reanalyses of three experiments from other laboratories, two involving instructed faking and one involving possibly motivated (...) faking. Across all studies involving instructed faking, CTS correctly classified 75% of intentionally faking participants. Using the CTS index to adjust faked Implicit Association Test scores increased the correlation of CTS-adjusted measures with known group membership, relative to unadjusted (i.e., faked) measures.

This paper briefly surveys previous analyses of implicitness and proposes a new, two-dimensional account. The first dimension concerns whether an assumption follows or not in terms of analytical or contextual implications or because it is a reasonable interpretation. The second dimension concerns the intentions of the author. Both dimensions are needed for identifying implicit assumptions in critical analyses of texts. A definition of clear cases of implicit assumptions is given. /// Este artículo examina brevemente análisis previos sobre lo (...) implícito y propone una nueva explicación bidimensional. La primera dimensión es sobre si se sigue o no una suposición en términos de implicaciones analíticas o contextuales, o porque la interpretación es razonable. La segunda dimensión se ocupa de las intenciones del autor. Ambas dimensiones son necesarias para identificar suposiciones implícitas en los análisis críticos de textos. Se proporciona una definición de los casos claros de supuestos implícitos. (shrink)

We report two studies on the effect of implicitly versus explicitly conveying affirmation and denial problems about conditionals. Recently Evans and Handley (1999) and Schroyens et al. (1999b, 2000b) showed that implicit referencing elicits matching bias: Fewer determinate inferences are made, when the categorical premise (e.g., B) mismatches the conditional's referred clause (e.g., A). Also, the effect of implicit affirmation (B affirms not-A) is larger than the effect of implicit denial (B denies A). Schroyens et al. hypothesised (...) that this interaction is due to uncertainty in the case-wise affirmation of the contrast class of negated elements involved in implicit affirmations. In Experiment 1 we tested this hypothesis by manipulating the set size of the conditional clauses. The results confirm that binary sets, where the contrast class is a singleton, eliminate the differential effect of implicit affirmation and denial. With non-binary sets the interaction is not modulated by the scope of the contrast class (3, 5, 9 elements). Experiment 2 further investigated the role of contrast classes by using class inclusion to construct implicit affirmations (Mammal vs Mammal or Monkey) and implicit denial (No-Mammal vs Mammal or Monkey), in addition to the standard implicit problems mediated by contrast-class inclusion [(No-)Mammal/No-Mammal; Reptile; Snake). Findings indicate that class inclusion (Mammal/Monkey; Reptile/ Snake) only marginally affects performance, and is independent of the type of problem. This would suggest that the implicitness problem-type interaction is dependent on constructing contrast classes. However, the experiment failed to replicate the interaction, even on the subset of problems repeating the abstract letter/number format of Experiment 1. Moreover, with the natural binary set-sizes (vowels/consonants) the implicitness effect was eliminated entirely. (shrink)
In the scientific study of mind a distinction is drawn between explicit knowledge— knowledge that can be elicited from a subject by suitable inquiry or prompting, can be brought to consciousness, and externally expressed in words—and implicit knowledge—knowledge that cannot be elicited, cannot be made directly conscious, and can- not be articulated. Michael Polanyi (1967) argued that we usually ‘know more than we can say’. The part we can articulate is explicitly known; the part we cannot is implicit.
