Time underlies many interesting human behaviors. Thus, the question of how to represent time in connectionist models is very important. One approach is to represent time implicitly by its effects on processing rather than explicitly (as in a spatial representation). The current report develops a proposal along these lines first described by Jordan (1986) which involves the use of recurrent links in order to provide networks with a dynamic memory. In this approach, hidden unit patterns are fed back to themselves: (...) the internal representations which develop thus reflect task demands in the context of prior internal states. A set of simulations is reported which range from relatively simple problems (temporal version of XOR) to discovering syntactic/semantic features for words. The networks are able to learn interesting internal representations which incorporate task demands with memory demands: indeed, in this approach the notion of memory is inextricably bound up with task processing. These representations reveal a rich structure, which allows them to be highly context‐dependent, while also expressing generalizations across classes of items. These representations suggest a method for representing lexical categories and the type/token distinction. (shrink)

Although for many years a sharp distinction has been made in language research between rules and words—with primary interest on rules—this distinction is now blurred in many theories. If anything, the focus of attention has shifted in recent years in favor of words. Results from many different areas of language research suggest that the lexicon is representationally rich, that it is the source of much productive behavior, and that lexically specific information plays a critical and early role in the interpretation (...) of grammatical structure. But how much information can or should be placed in the lexicon? This is the question I address here. I review a set of studies whose results indicate that event knowledge plays a significant role in early stages of sentence processing and structural analysis. This poses a conundrum for traditional views of the lexicon. Either the lexicon must be expanded to include factors that do not plausibly seem to belong there; or else virtually all information about word meaning is removed, leaving the lexicon impoverished. I suggest a third alternative, which provides a way to account for lexical knowledge without a mental lexicon. (shrink)

Periodically in science there arrive on the scene what appear to be dramatically new theoretical frameworks (what the philosopher of science Thomas Kuhn has called paradigm shifts). Characteristic of such changes in perspective is the recasting of old problems in new terms. By altering the conceptual vocabulary we use to think about problems, we may discover solutions which were obscured by prior ways of thinking about things. Connectionism, artificial life, and dynamical systems are all approaches to cognition which are relatively (...) new and have been claimed to represent such paradigm shifts. Just how deep the shifts are remains an open question, but each of these approaches certainly seems to offer novel ways of dealing with basic questions in cognitive science. (shrink)

Anticipation plays a role in language comprehension. In this article, we explore the extent to which verb sense influences expectations about upcoming structure. We focus on change of state verbs like shatter, which have different senses that are expressed in either transitive or intransitive structures, depending on the sense that is used. In two experiments we influence the interpretation of verb sense by manipulating the thematic fit of the grammatical subject as cause or affected entity for the verb, and test (...) whether readers’ expectations for a transitive or intransitive structure change as a result. This sense‐biasing context influenced reading times in the postverbal regions. Reading times for transitive sentences were faster following good‐cause than good‐theme subjects, but the opposite pattern was found for intransitive sentences. We conclude that readers use sense‐contingent subcategorization preferences during on‐line comprehension. (shrink)

The nature–nurture controversy has been with us since it was first outlined by Plato and Aristotle. Nobody likes it anymore. All reasonable scholars today agree that genes and environment interact to determine complex cognitive outcomes. So why does the controversy persist? First, it persists because it has practical implications that cannot be postponed (i.e., what can we do to avoid bad outcomes and insure better ones?), a state of emergency that sometimes tempts scholars to stake out claims they cannot defend. (...) Second, the controversy persists because we lack a precise, testable theory of the process by which genes and the environment interact. In the absence of a better theory, innateness is often confused with (1) domain specificity (outcome X is so peculiar that it must be innate), (2) species specificity (we are the only species who do X, so X must lie in the human genome), (3) localization (outcome X is mediated by a particular part of the brain, so X must be innate), and (4) learnability (we cannot figure out how X could be learned, so X must be innate). We believe that an explicit, plausible theory of interaction is now around the corner, and that many of the classic maneuvers to defend or attack innateness will soon disappear. In the interim, some serious errors can be avoided if we keep these confounded issues apart. That is the major goal of this chapter: not to attack innateness but to clarify what claims about innateness are (and are not) about. (shrink)

McRae, Brown and Elman argue against the view that events are structured as frequently‐occurring sequences of world stimuli. They underline the importance of temporal structure defining event types and advance a more complex temporal structure, which allows for some variance in the component elements.

For more than three decades, research into the psycholinguistics of pronoun interpretation has argued that hearers use various interpretation ‘preferences’ or ‘strategies’ that are associated with specific linguistic properties of antecedent expressions. This focus is a departure from the type of approach outlined in Hobbs , who argues that the mechanisms supporting pronoun interpretation are driven predominantly by semantics, world knowledge and inference, with particular attention to how these are used to establish the coherence of a discourse. On the basis (...) of three new experimental studies, we evaluate a coherence-driven analysis with respect to four previously proposed interpretation biases—based on grammatical role parallelism, thematic roles, implicit causality, and subjecthood—and argue that the coherence-driven analysis can explain the underlying source of the biases and predict in what contexts evidence for each will surface. The results further suggest that pronoun interpretation is incrementally influenced by probabilistic expectations that hearers have regarding what coherence relations are likely to ensue, together with their expectations about what entities will be mentioned next, which, crucially, are conditioned on those coherence relations.

The forms of words as they appear in text and speech are central to theories and models of lexical processing. Nonetheless, current methods for simulating their learning and representation fail to approach the scale and heterogeneity of real wordform lexicons. A connectionist architecture termed thesequence encoderis used to learn nearly 75,000 wordform representations through exposure to strings of stress‐marked phonemes or letters. First, the mechanisms and efficacy of the sequence encoder are demonstrated and shown to overcome problems with traditional slot‐based (...) codes. Then, two large‐scale simulations are reported that learned to represent lexicons of either phonological or orthographic wordforms. In doing so, the models learned the statistics of their lexicons as shown by better processing of well‐formed pseudowords as opposed to ill‐formed (scrambled) pseudowords, and by accounting for variance in well‐formedness ratings. It is discussed how the sequence encoder may be integrated into broader models of lexical processing. (shrink)

Sibley, Kello, Plaut, and Elman (2008) proposed the sequence encoder as a model that learns fixed‐width distributed representations of variable‐length sequences. In doing so, the sequence encoder overcomes problems that have restricted models of word reading and recognition to processing only monosyllabic words. Bowers and Davis (2009) recently claimed that the sequence encoder does not actually overcome the relevant problems, and hence it is not a useful component of large‐scale word‐reading models. In this reply, it is noted that the (...) sequence encoder has facilitated the creation of large‐scale word‐reading models. The reasons for this success are explained and stand as counterarguments to claims made by Bowers and Davis. (shrink)

PurposeThis study investigated whether the ability to utilize statistical regularities from fluent speech and map potential words to meaning at 18-months predicts vocabulary at 18- and again at 24-months.MethodEighteen-month-olds were exposed to an artificial language with statistical regularities within the speech stream, then participated in an object-label learning task. Learning was measured using a modified looking-while-listening eye-tracking design. Parents completed vocabulary questionnaires when their child was 18-and 24-months old.ResultsAbility to learn the object-label pairing for words after exposure to the artificial (...) language predicted productive vocabulary at 24-months and amount of vocabulary change from 18- to 24 months, independent of non-verbal cognitive ability, socio-economic status and/or object-label association performance.ConclusionEighteen-month-olds’ ability to use statistical information derived from fluent speech to identify words within the stream of speech and then to map the “words” to meaning directly predicts vocabulary size at 24-months and vocabulary change from 18 to 24 months. The findings support the hypothesis that statistical word segmentation is one of the important aspects of word learning and vocabulary acquisition in toddlers. (shrink)

An essential aspect of knowing language is knowing the words of that language. This knowledge is usually thought to reside in the mental lexicon, a kind of dictionary that contains information regarding a word’s meaning, pronunciation, syntactic characteristics, and so on. In this article, a very different view is presented. In this view, words are understood as stimuli that operate directly on mental states. The phonological, syntactic and semantic properties of a word are revealed by the effects it has on (...) those states. (shrink)

In this article, we examine how affect influences judgment and thought, but also how thought transforms affect. The general thesis is that the nature and impact of affective reactions depends largely on their objects. We view affect as a representation of value, and its consequences as dependent on its object or what it is about. Within a review of relevant literature and a discussion of the nature of emotion, we focus on the role of the object of affect in governing (...) both the nature of emotional reactions and the impact of affect and emotion on cognition and action. Although emotion is always about the here and now, the capacity for abstract thought means that the human here and now includes imagination as well as perception. Indeed, the hopes and fears that dominate human lives often involve things only imagined. (shrink)

This is a comprehensive and authoritative handbook featuring essays from some of the most respected scholars in the field. (shrink)

Ethics has been identified as an important factor that potentially affects auditors’ professional skepticism. For example, prior research finds that auditors who are more concerned with professional ethics exhibit greater professional skepticism. Further, the literature suggests that professional skepticism may lead the auditor to more vigilantly resist the client’s position in financial reporting disputes. These reporting disputes are generally resolved through negotiations between the auditor and client to arrive at the final reported amounts. To date, the role that professional skepticism (...) potentially plays in the negotiation process has been relatively unexplored. The literature prior to the enactment of Sarbanes–Oxley (SOX) suggests that auditors are more likely to approve a client position when the matter in dispute is relatively ambiguous and when changing the client’s position will result in the client failing to meet analysts’ expectations. However, changes resulting from SOX have led auditors to be more vigilant and therefore results found in the pre-SOX environment may not hold in the current environment where auditors are held more accountable for their actions. Results from an experiment with experienced audit managers and partners suggest that in the post-SOX climate, auditors’ negotiations do not appear to be substantively influenced by management being able to meet or beat forecasts. Moreover, we find that when auditors exhibit heightened professional skepticism, they are more ethical by being conservative and they stand more resolute than when auditors do not exhibit heightened professional skepticism. Finally, although we do not find a main effect for the influence of earnings forecast, we do find a significant interaction between earnings forecast and heightened professional skepticism. Implications for practice and research are then presented. (shrink)

In Black Museum, a young woman is out to take revenge on the man who imprisoned her father's digital self in a museum exhibit that allows sadistic visitors to reenact his execution. While the exhibit is morally detestable and some may think that the museum's curator gets what he deserves in the end, the woman's act of vengeance is morally disturbing. This chapter explores Martha Nussbaum's account of anger and forgiveness and considers Christian and Buddhist teachings. An argument by David (...) Kyle Johnson for the moral permissibility of revenge under certain circumstances is considered and rejected. The authors conclude that the act of revenge in Black Museum is not morally justified.

Commentaries focused on the emotional appraisal part of our article. Cunningham and Van Bavel argued for distinguishing core disgust from moral disgust, and we describe how the theory might accommodate their proposal. They also suggested that temporal and other comparisons could account for emotional variety. We concur, but see such comparisons as inherent in the different emotional objects. Winkielman emphasized unconscious affect, but we suggest its power flows from the absence of situational constraints on its meaning. He characterized our appraisal (...) model as coldly cognitive rather than embodied, but the complaint is misdirected, as the model addresses emotional structure, not emotional process. Indeed, embodied accounts will still require structural accounts to determine why one emotion rather than another is elicited. (shrink)

Epidemiology is a core science of public health, focusing on research related to the distribution and determinants of both positive and adverse health states and events and on application of knowledge gained to improve public health. The American College of Epidemiology (ACE) is a professional organization devoted to the professional practice of epidemiology. As part of that commitment, and in response to concerns for more explicit attention to core values and duties of epidemiologists in light of emerging issues and increased (...) scrutiny of epidemiology, the College developed, adopted, and published a set of Ethics Guidelines. The structure of the ACE ethics guidelines is in four parts: (1) a brief statement of core values and duties of epidemiologists, coupled with the virtues important to professional practice; (2) concise statements of key duties and obligations; (3) exposition of the duties and obligations with more applications; and (4) a brief summary and conclusion. The Guidelines have been published on the ACE website and in the official College journal Annals of Epidemiology. The guidelines contain (and maintain) core elements that define the discipline of epidemiology and its fundamental duties, but they are also intended to be dynamic and evolving, responsive to a changing professional and social environment.

The aesthetic experience may be defined as people's interactions with, and reactions to, objects, places, but also to the environment. Most psychological perspectives on the aesthetic experience argue that it results from the coordination of different mental processes such as perception, attention, memory, imagination, thought, and emotion. Physiological and neurological responses are also involved. Aesthetic experiences can take place while we observe works of art in museums and galleries as well as in other contexts such as natural and built environments. (...) Looking at a landscape, walking in a park, meeting people in a square, and walking into a building that is architecturally appealing are examples of natural and built environments where we can experience beauty, pleasure, attraction, and interest, among other aesthetic reactions.Research on aesthetic experiences has a long history, and in recent decades, the field has experienced tremendous growth in the number of empirical studies conducted. One of the areas that researchers have yet to fully address is the influence of the context (natural and built environments) on aesthetic experiences. We refer to context according to three broad categories: Context as natural environments, context as built environments, and environments for aesthetic experiences.Context as natural environments: People show a basic tendency to associate the natural environment with positive evaluations.

Access to a deep pool of talent is essential to the success of every professional services firm. The supply of that talent is contingent upon the available rewards for the exercise of that talent, and both the existence of the potential rewards and the beliefs that individuals hold about the existence of the rewards affect the decision to remain in the field. One structural factor that may affect the judgment about whether to remain in a profession concerns promotions based on (...) the gender of the employee. In this study, we examine the “glass ceiling” within the context of the accounting profession. While advances have been made within the accounting profession to address the glass ceiling, the continued existence—and perceptions about the continued existence—of the issue exert adverse effects upon the available talent pool and may create long-term problems for the profession. In this study, we investigate glass ceiling perceptions among a large sample of female accounting professionals employed in accounting; the sample includes both public accountants, and those employed in industry accounting. Our study yields the finding of beliefs in bias-driven effects, structural effects, and cultural effects among these accounting professionals. Glass ceiling perceptions are also influenced by several demographic factors. Furthermore, accounting professionals employed by industry are more likely to report a glass ceiling within their firms than accounting professionals employed by public accounting firms. The findings are of interest to researchers who explore gender-related issues in professional service firms such as the field of accounting, and to senior members of practice who are tasked with ensuring the integrity and quality of the talent pool and the equitable distribution of rewards to employees.
