John Searle raised the question whether all computation is observer-relative. Indeed, all of the common views of computation, be they semantical, functional or causal rely on mapping something onto the states of a physical or abstract process. In order to effectively execute such a mapping, this process would have to be observed in some way. Thus a probably syntactical analysis by an observer seems to be essential for judging whether a given process implements some computation or not. In (...) order to be able to explore the nature of these observers in a more formal way, we look at the Computing by Observing paradigm, a theoretical model of computation that includes an observer. We argue that the observers used there, monadic transducers, are good candidates for formalizing the way in which the syntax of a process must be analysed in order to judge whether it is computational.

Observables have a dual nature in both classical and quantum kinematics: they are at the same time quantities, allowing to separate states by means of their numerical values, and generators of transformations, establishing relations between different states. In this work, we show how this twofold role of observables constitutes a key feature in the conceptual analysis of classical and quantum kinematics, shedding a new light on the distinguishing feature of the quantum at the kinematical level. We first take a (...) look at the algebraic description of both classical and quantum observables in terms of Jordan–Lie algebras and show how the two algebraic structures are the precise mathematical manifestation of the twofold role of observables. Then, we turn to the geometric reformulation of quantum kinematics in terms of Kähler manifolds. A key achievement of this reformulation is to show that the twofold role of observables is the constitutive ingredient defining what an observable is. Moreover, it points to the fact that, from the restricted point of view of the transformational role of observables, classical and quantum kinematics behave in exactly the same way. Finally, we present Landsman’s general framework of Poisson spaces with transition probability, which highlights with unmatched clarity that the crucial difference between the two kinematics lies in the way the two roles of observables are related to each other.

In this paper, aspects of observable and non-observable based models are discussed. A survey of recent literature was done to show how using non-observable-based language carelessly may cause disagreement, even in professional research programs and incorrect assertions, even in prestigious journals. The relation between physical measurements and observables is discussed and it is shown that, in contrast to general belief, this relation may be complicated and not always straightforward. The decomposition of the system into basic subsystems (physical or conceptual) is (...) traced as the origin of non-observable-based languages. The possibility of defining new quantum mechanical observables for open quantum subsystems and of replacing them with non-observable-based concepts has been mentioned and the AIM theory is explained as an example. An account of some current non-observable-based models for molecular geometry is discussed and it is shown that not all non-observable-based languages possess the same effectiveness. In the end, the need to develop a clear chemical language is stressed. (shrink)

As the number of consumer transgressions continues to increase, so do their financial repercussions for companies. Though academic and managerial interest in addressing this issue is growing, research on how to dissuade consumers from committing transgressions remains scarce. Drawing on the mental imagery literature and normative moral theory, the present research examines a novel way of reducing consumers’ appraisals of their own transgressions. Whereas an actor-imagery perspective fosters a teleological, egoistic view of morality and, in turn, induces moral leniency, having (...) consumers adopt an observer-imagery perspective fosters a deontological view of morality and, in turn, induces moral stringency. The effects are robust across various types of consumer transgressions, including the purchase of counterfeit products and return fraud in the form of wardrobing. Study 2 also rules out vividness as an alternative explanation for these effects. Theoretical and managerial implications are discussed. (shrink)

Theodosius Dobzhansky has long been recognized by historians as a pioneer in the combining of the 'field natural history' and 'laboratory experimentalist' traditions in biology (Allen 1994). The following essay analyzes two papers in his wellknown Genetics of Natural Populations series, GNP IX and GNP XII, which demonstrate how Dobzhansky combined field and laboratory work in the pursuit of an evolutionary question. The analysis reveals the multiple and complementary roles field observations and experiments played in his investigations. But it also (...) identifies several interpretive problems associated with the use of intervention that limited the effectiveness of his approach. The essay argues that these problems reflect a fundamental tension between the amount of control Dobzhansky had over the circumstances of his experiments and the applicability of his results to natural populations. It concludes that this trade-off represents an important distinction between experiments in biology and most other sciences. (shrink)

This study investigates why and when employees’ observations of supervisors’ ostracism of coworkers elicit their own feelings of guilt. In this connection, observers’ silence might function as a mediator, and leader–member exchange quality could moderate the process. The tests of these predictions rely on two studies, undertaken in Pakistan: a temporally separated field study using three-wave data (N = 219) and a scenario-based experiment (N = 118). The combined results indicate that employees feel guilty for remaining silent when they witness (...) supervisor ostracism of other colleagues. The positive relationship between such observations of supervisor ostracism and silence behavior is more pronounced among employees who enjoy high-quality relationships with their supervisor. In addition to establishing key theoretical insights, this article alerts organizations to a critical mechanism (silence to avoid upsetting supervisors) by which employees’ observations of how supervisors ostracize others can escalate into their own sense of guilt.

Although quantum mechanics has significantly advanced our understanding of the physical world, it has also been a source of great confusion. Myriad interpretations, and interpretations of interpretations, have been proposed to try and explain away the seeming inconsistencies which lie at the heart of quantum mechanics. All of these attempts at interpretation center on the seemingly intractable measurement problem. In this essay I argue that a number of interpretations of quantum mechanics are plagued by inadequate and misleading assumptions about the (...) observer. These assumptions are based on a naïve “folk conception” of the observer. In discussing two phenomena studied in modern cognitive science, I will argue for a rejection of the naïve conception of the observer and adopt a more sophisticated view which offers a significant interpretational payoff. I argue that although the measurement problem in quantum mechanics appears to be a scientific problem requiring a scientific solution, it is plausible that the problem might be a pseudo-problem resulting from a conceptual confusion. The conceptual confusion is caused by naïve assumptions about the nature of the observer.1 Based on these arguments I will reevaluate a number of interpretations and assess the role of philosophy in interpreting quantum mechanics.

Previous studies have focused on individuals learning from observing a model to be able to produce the modeled behavior. However, there is a lack of studies emphasizing the perspective of being observed to understand the role of perceived value and stress when teachers act as a teaching model. To address this gap, the present study explored the correlates between teachers’ teaching beliefs, perceived value, psychosocial stress, and continuous intention to be the observed teaching model in classroom observations. Data of (...) 349 respondents were usefully collected, and confirmatory factor analysis with structural equation modeling was performed. Results showed that teachers’ constructivist belief in teaching was positively related to perceived value of being observed and getting feedback, but was negatively related to psychosocial stress. Perceived value was positively related to continuous intention to be observed in future classroom observations, but perceived psychosocial stress was not significantly related to continuous intention. The results of this study can be applied to encourage those who are resistant to presenting their teaching experience in classroom observations. (shrink)

Recent years have seen an upsurge of interest in the second-person perspective, not only in philosophy of mind, language, law and ethics, but also in various empirical disciplines such as cognitive neuroscience and developmental psychology. A distinctive and perhaps also slightly puzzling feature of this ongoing discussion is that whereas many contributors insist that a proper consideration of the second-person perspective will have an impact on our understanding of social cognition, joint action, communication, self-consciousness, morality, and so on, there remains (...) considerable disagreement about what exactly a second-person perspective amounts to (see Eilan 2014; Conant and Rödl 2014). What is the difference between adopting a second-person and a third-person perspective on another? How does one relate to another as a you and how does that differ from relating to another as a he, she or they? In the following, I will consider three different proposals and argue that a promising but somewhat overlooked account can be found in the work of Husserl. (shrink)

The issue of the theory-ladenness of observation has long troubled philosophers of science, largely because it seems to threaten the objectivity of science. However, the way in which prior beliefs influence the perception of data is in part an empirical issue that can be investigated by cognitive psychology. This point is illustrated through an experimental analogue of scientific data-interpretation tasks in which subjects judging the covariation between personality variables based their judgments on pure data, their theoretical intuitions about the variables, (...) or both data and prior theoretical beliefs. Results showed that the perceived magnitude of correlations was greatest when subjects relied solely on theoretical intuitions; that data-based judgments were drawn in the direction of those prior beliefs; but that exposure to data nonetheless moderated the strength of the prior theories. In addition, prior beliefs were found to influence judgments only after a brief priming interval, suggesting that subjects needed time to retrieve their theoretical intuitions from memory. These results suggest ways to investigate the processes mediating theory-laden observation, and, contrary to the fears of positivist philosophers, imply that the theory-ladenness of observation does not entail that theoretical beliefs are immune to data.

The distinction between psychology, logic, and epistemology is a commonplace. The first treats of experience as an act, experience in its relation to the individual observer. The second concerns itself with the internal marks by which truth may be distinguished from error, and in so far as it deals with experience, has to do with some sort of validity of the experience as evidence of a truth. The third discusses in a general way all the elements—observer, object, immediate (...) presentation—which enter into the experience. (shrink)

Bohmian mechanics is arguably the most naively obvious embedding imaginable of Schr¨ odinger’s equation into a completely coherent physical theory. It describes a world in which particles move in a highly non-Newtonian sort of way, one which may at first appear to have little to do with the spectrum of predictions of quantum mechanics. It turns out, however, that as a consequence of the defining dynamical equations of Bohmian mechanics, when a system has wave function ψ its configuration is typically (...) random, with probability density ρ given by |ψ|2, the quantum equilibrium distribution. It also turns out that the entire quantum formalism, operators as observables and all the rest, naturally emerges in Bohmian mechanics from the analysis of “measurements.” This analysis reveals the status of operators as observables in the description of quantum phenomena, and facilitates a clear view of the range of applicability of the usual quantum mechanical formulas.

Much recent discussion in the aesthetics of nature has focused on Scientific cognitivism, the view that in order to engage in a deep and appropriate aesthetic appreciation of nature, one must possess certain kinds of scientific knowledge.

Despite the vast amount of work produced by philosophers, historians and sociologists on the nature of scientific activity, “observation itself is rarely the focus of attention and almost never the subject of historical inquiry in its own right”.

Abstract During the last decades it has become widely accepted that scientific observations are ?theory?laden?. Scientists ?see? the world with their theories or theoretical presuppositions. In the present paper it is argued that they ?see? with their scientific instruments as well, as the uses of scientific instruments is an important characteristic of modern natural science. It is further argued that Euclidean geometry is intimately linked to technology, and hence that it plays a fundamental part in the construction and operation of (...) scientific instruments. Finally, Euclidean geometry is compared to fractal geometry, and the question of its a priori status is raised. Although the position that Euclidean geometry is a priori in the original Kantian sense is untenable, the paper concludes that in some restricted sense Euclidean geometry may be said to be a priori.

In the prior studies, the significance of working memory is linked to language acquisition which helped in understanding these disorders better (Wen, & Li, 2019). However, there is one component that is not being taken into consideration with Second Language Acquisition (SLA) (Choi, 2019). This study collected data from 122 adolescents and young adults (Female = 61, Male = 61) in the age range 15–22 years. Using four subtests of David’s Battery of Differential Abilities (DBDA), measures of VSSP and verbal (...) ability were measured. Multiple regression analysis was carried out between the measures of VSSP and verbal ability. The results showed promise and the measures of VSSP were found to be a positive predictor of second language comprehension in the current sample. Whereas, no gender differences were observed with regard to verbal ability. With the supporting literature, this study evidently provided insights into the overall relationship. (shrink)

The "observer" approach is investigated as a device for developing ethical theory, not for its use in private moral decision-making. Earlier discussions by Firth, Brandt, Harrison and Aiken of the impartial spectator are related to eighteenth-century British and German ethics using this theme, in order to uncover the meanings of the observer theory. Advantages and disadvantages of this approach to ethics are then examined, and the conclusion is that it does not provide a complete basis for ethical discourse (...) but is of limited use in developing some general principles in a ruleethics.

At first glance singularity would seem to be necessarily opposed to the physical sciences, indeed to any kind of science. As the hallowed saying goes: “Science deals only in universals.” According to this view, the aim of any true scientific endeavor must be the discovery of universals or, in other words, the value of such an endeavor is based on its ability to explain phenomena in terms of universals. The status of singularity in science is a direct result of this (...) approach. Singularity is associated with the presence, either in a person or an object, of an unusual or exceptional quality, or of an individual trait. Singularity so conceived must therefore be seen as inherently compromising the aims of any scientific endeavor, since the purpose of that endeavor is universality as defined above. In this sense, the basis of scientific explication is the ability to determine a feature common to a collection of objects, thus allowing them to be explained by deductive reasoning. This common feature can therefore not be individual, if individual is understood as unusual or exceptional. (shrink)

The study ascertained (1) whether an observer's scope of justice with reference to either the moral agent or the target person of a moral act, would affect his/her judgements of the ethicality of the act, and (2) whether observer judgements of ethicality parallel the moral agent's decision processes in systematically evaluating the intensity of the moral issue. A scenario approach was used. Results affirmed both research questions. Discussions covered the implications of the findings for the underlying cognitive processes (...) of moral judgements, for the link between judgements of fairness and ethicality, as well as for the debate of ethical absolutism versus relativism.

This article examines the role of historical science in clarifying the causal structure of complex natural processes. I reject the pervasive view that historical science does not uncover natural regularities.

I provide several case studies that illustrate this, including one that highlights how historical narratives (...) can improve predictive models. (shrink)

In the past two decades, reinforcement learning has become a popular framework for understanding brain function. A key component of RL models, prediction error, has been associated with neural signals throughout the brain, including subcortical nuclei, primary sensory cortices, and prefrontal cortex. Depending on the location in which activity is observed, the functional interpretation of prediction error may change: Prediction errors may reflect a discrepancy in the anticipated and actual value of reward, a signal indicating the salience or novelty of (...) a stimulus, and many other interpretations. Anterior cingulate cortex has long been recognized as a region involved in processing behavioral error, and recent computational models of the region have expanded this interpretation to include a more general role for the region in predicting likely events, broadly construed, and signaling deviations between expected and observed events. Ongoing modeling work investigating the interaction between ACC and additional regions involved in cognitive control suggests an even broader role for cingulate in computing a hierarchically structured surprise signal critical for learning models of the environment. The result is a predictive coding model of the frontal lobes, suggesting that predictive coding may be a unifying computational principle across the neocortex. (shrink)

On standard accounts of scientific theorizing, the role of idealizations is to facilitate the analysis of some real world system by employing a simplified representation of the target system, raising the obvious worry about how reliable knowledge can be obtained from inaccurate descriptions. The idealizations involved in the Aharonov–Bohm effect do not, it is claimed, fit this paradigm; rather the target system is a fictional system characterized by features that, though physically possible, are not realized in the actual world. (...) The point of studying such a fictional system is to understand the foundations of quantum mechanics and how its predictions depart from those of classical mechanics. The original worry about the use of idealizations is replaced by a new one; namely, how can actual world experiments serve to confirm the AB effect if it concerns the behavior of a fictional system? Struggle with this issue helps to account for the fact that almost three decades elapsed before a consensus emerged that the predicted AB effect had received solid experimental support. Standard accounts of idealizations tout the role they play in making tractable the analysis of the target system; by contrast, the idealizations involved in the AB effect make its analysis both conceptually and mathematically challenging. The idealizations required for the AB effect are also responsible for the existence of unitarily inequivalent representations of the canonical commutation relations and of the current algebra, representations which an observer confined to the electron’s configuration space could invoke to ‘explain’ AB-type effect without the need to posit a hidden magnetic field. The goal of this paper is to bring to the attention of the philosophers of science these and other aspects of the AB effect which are neglected or inadequately treated in literature. (shrink)

Measurement outcomes are frequently used as evidence in favor of or against medical and surgical interventions, health policies, and system designs. Indeed, in the medical and health services research literature, outcomes are the currency of policy debate and decision making. Yet in the philosophy of science and philosophy of medicine, the measures used in evidence-based medicine (EBM) are rarely discussed. Rather, the focus here is almost exclusively on study design and hierarchies of evidence. This concentration on the methodology of study (...) design has meant that for practical purposes the measures used in randomized controlled trials, observational studies, audits, and so forth, appear as a “black box.” Yet as I argue in the first part of this article, an engagement with measurement can improve our understanding of EBM and the quality of our evidence. In the second part of the article, I develop such an engagement with one aspect of measurement, namely, the validity of patient-reported outcome measures. Here, I illustrate some of the complexity that is required to improve the validity of these measures and hence the validity of our study outcomes, that is, evidence. The concentration in philosophy of science on study design over measurement methodology perhaps reveals the interest that many philosophers of medicine have in causation, but there is more to the production of high-quality scientific evidence than securing the causal inference.

Through a study of a sophisticated contemporary scientific experiment, it is shown how and why use of the term 'observation' in reference to that experiment departs from ordinary and philosophical usages which associate observation epistemically with perception. The role of "background information" is examined, and general conclusions are arrived at regarding the use of descriptive language in and in talking about science. These conclusions bring out the reasoning by which science builds on what it has learned, and, further, how (...) that process of building consists not only in adding to our substantive knowledge, but also in increasing our ability to learn about nature, by extending our ability to observe it in new ways. The argument of this paper is thus a step toward understanding how it is that all our knowledge of nature rests on observation. (shrink)

Proponents of Evidence-based medicine (EBM) do not provide a clear role for basic science in therapeutic decision making. Of what they do say about basic science, most of it is negative. Basic science resides on the lower tiers of EBM's hierarchy of evidence. Therapeutic decisions, according to proponents of EBM, should be informed by evidence from randomised studies (and systematic reviews of randomised studies) rather than basic science. A framework of models explicates the links between the mechanisms of basic (...) science, experimental inquiry, and observed data. Relying on the framework of models I show that basic science often plays a role not only in specifying experiments, but also analysing and interpreting the data that is provided. Further, and contradicting what is implied in EBM's hierarchy of evidence, appeals to basic science are often required to apply clinical research to therapeutic questions. © 2010 Springer Science+Business Media B.V.

The purpose of this article is to develop an epistemology of scientific models in scientific research practices, and to show that disciplinary perspectives have crucial role in such an epistemology. A transcendental approach is taken, aimed at explanations of the kinds of questions relevant to the intended epistemology, such as “How is it possible that models provide knowledge about aspects of reality?” The approach is also pragmatic in the sense that the questions and explanations must be adequate and relevant (...) to concrete scientific practice. First it is explained why the idea of models as representations in terms of similarity or isomorphism between a model and its target is too limited as a basis for this epistemology. An important finding is that the target-phenomenon is usually not something that can be observed in a straightforward manner, but requires both characterization in terms of measurable variables and subsumption under concepts. The loss of this basis leads to a number of issues, such as: how can models be interpreted as representations if models also include conceptually meaningful linguistic content; how can researchers identify non-observable real-world target-phenomena that are then represented in the model; how do models enable inferential reasoning in performing epistemic tasks by researchers; and, how to justify scientific models. My proposal is to deal with these issues by analyzing how models are constructed, rather than by looking at ready-made models. Based on this analysis, I claim that the identification of phenomena and the construction of scientific models is guided and also confined by the disciplinary perspective within which researchers in a scientific discipline have learned to work. I propose a Kuhnian framework by which the disciplinary perspective can be systematically articulated. Finally, I argue that harmful forms of subjectivism, due to the loss of the belief that models objectively represent aspects of reality, can be overcome by making the disciplinary perspective in a research project explicit, thereby enabling its critical assessment, for which the proposed Kuhnian framework provides a tool.

What role do nurses play in euthanasia? How do they experience this role and what should be their ideal role? These are the questions of a study undertaken to gain insight into the role of nurses in euthanasia. Answers to these questions were derived from 20 semistructured in-depth interviews with nurses employed in a Dutch hospital. To make clear the role of nurses in euthanasia, the issue was split up into four phases: observation of a (...) request for euthanasia; decision making; carrying out of the request; and after-care. This article is a brief report on the most important results regarding these four phases. Special attention will be paid to nurses who have conscientious objections. To evaluate the study results, an unambiguous interpretation of the concept of ‘euthanasia’ is of most importance. For that reason, Dutch laws and other regulations concerning euthanasia will be explained. (shrink)

The role of cognitive control mechanisms in reducing interference from emotionally salient distractors was investigated. In two experiments, participants performed a flanker task in which target-distractor affective compatibility and cognitive load were manipulated. Differently from past studies, targets and distractors were presented at separate spatial locations and cognitive load was not domain-specific. In Experiment 1, words and faces, were used respectively as targets and distractors, whereas in Experiment 2, both targets and distractors were faces. Findings showed interference from distractor (...) processing only when cognitive load was high. The present findings indicate that, when targets and distractors are presented at different spatial locations, cognitive control mechanisms are involved in preventing interference from positive or negative distractors. The role of stimulus valence and type is also discussed with regard to different patterns of interference observed. (shrink)

Research in education and cognitive development suggests that explaining plays a key role in learning and generalization: When learners provide explanations—even to themselves—they learn more effectively and generalize more readily to novel situations. This paper proposes and tests a subsumptive constraints account of this effect. Motivated by philosophical theories of explanation, this account predicts that explaining guides learners to interpret what they are learning in terms of unifying patterns or regularities, which promotes the discovery of broad generalizations. Three experiments (...) provide evidence for the subsumptive constraints account: prompting participants to explain while learning artificial categories promotes the induction of a broad generalization underlying category membership, relative to describing items (Exp. 1), thinking aloud (Exp. 2), or free study (Exp. 3). Although explaining facilitates discovery, Experiment 1 finds that description is more beneficial for learning item details. Experiment 2 additionally suggests that explaining anomalous observations may play a special role in belief revision. The findings provide insight into explanation’s role in discovery and generalization. (shrink)

In this paper we analyse the role of description in qualitative research. Our point is this: the description itself has a necessary role in qualitative research; though that role is necessary, it is not enough, interpretation is also necessary, but this interpretation must be supported on a realist epistemology setting up clearly what is observation. In order to defend this point we show some problems in the relationship description-interpretation; then, we choose two proposals that defend the (...) class='Hi'>role of description in qualitative research; finally, we respond what is the role of description in qualitative research.

Although widely studied in other domains, relatively little is known about the metacognitive processes that monitor and control behaviour during reasoning and decision-making. In this paper, we examined the conditions under which two fluency cues are used to monitor initial reasoning: answer fluency, or the speed with which the initial, intuitive answer is produced, and perceptual fluency, or the ease with which problems can be read. The first two experiments demonstrated that answer fluency reliably predicted Feeling of Rightness judgments to (...) conditional inferences and base rate problems, which subsequently predicted the amount of deliberate processing as measured by thinking time and answer changes; answer fluency also predicted retrospective confidence judgments. Moreover, the effect of answer fluency on reasoning was independent from the effect of perceptual fluency, establishing that these are empirically independent constructs. In five experiments with a variety of reasoning problems similar to those of Alter et al., we found no effect of perceptual fluency on FOR, retrospective confidence or accuracy; however, we did observe that participants spent more time thinking about hard to read stimuli, although this additional time did not result in answer changes. In our final two experiments, we found that perceptual disfluency increased accuracy on the CRT, but only amongst participants of high cognitive ability. As Alter et al.’s samples were gathered from prestigious universities, collectively, the data to this point suggest that perceptual fluency prompts additional processing in general, but this processing may results in higher accuracy only for the most cognitively able.

Recently there have emerged an assortment of theorems relating to the ‘absoluteness of emerged events,’ and these results have sometimes been used to argue that quantum mechanics may involve some kind of metaphysically radical non-absoluteness, such as relationalism or perspectivalism. However, in our view a close examination of these theorems fails to convincingly support such possibilities. In this paper we argue that the Wigner’s friend paradox, the theorem of Bong et al and the theorem of Lawrence et al are all (...) best understood as demonstrating that if quantum mechanics is universal, and if certain auxiliary assumptions hold, then the world inevitably includes various forms of ‘disaccord,’ but this need not be interpreted in a metaphysically radical way; meanwhile, the theorem of Ormrod and Barrett is best understood either as an argument for an interpretation allowing multiple outcomes per observer, such as the Everett approach, or as a proof that quantum mechanics cannot be universal in the sense relevant for this theorem. We also argue that these theorems taken together suggest interesting possibilities for a different kind of relational approach in which _interaction_ states are relativized whilst observed events are absolute, and we show that although something like ‘retrocausality’ might be needed to make such an approach work, this would be a very special kind of retrocausality which would evade a number of common objections against retrocausality. We conclude that the non-absoluteness theorems may have a significant role to play in helping converge towards an acceptable solution to the measurement problem. (shrink)
