People usually fail the Wason selection task, choosing P and Q cases, when attempting to validate descriptive rules having the form “If P, then Q.” Yet they solve it, selecting P and not-Q cases, when validating deontic rules of the form “If P, then must Q.” The field of evolutionary psychology has overwhelmingly interpreted deontic versions of the selection task in terms of a naturally-selected, domain-specific social-contract or cheating algorithm. This work has done much to promote evolutionary psychology as an (...) alternative to a mindblind sociobiology that ignores the computational structure of cognitive mechanisms in producing people's behaviors. Nevertheless, evolution-minded researchers outside cognitive psychology know little of the ample literature challenging this interpretation and uncritically cite the “cheater-detection module” as a key insight into human cognition. Although a priori arguments for a specially evolved cheater-detection module are plausible, the selection task provides no direct evidence for such a module. (shrink)

The cheater-detection (CD) hypothesis suggests that people who otherwise perform poorly on the Wason selection task perform well when the task is couched in cheater-detection contexts. We report three studies with new selection problems that are similar to the originals but that question the CD hypothesis. The first two studies document a pattern heretofore attributed to CD mechanisms, namely good performance with “regular” rules and inferior performance with “switched” rules, all in problems that lack a (...) class='Hi'>cheater-detection context. The final study finds an interaction: not only is good performance elicited on non-CD problems, but poor performance is found in the context of CD problems. Performance on the selection task cannot be predicted based on the presence or absence of cheater-detection contexts, which brings into question the need to invoke a specialised cheater-detection module.

Evolutionary psychology—in its ambitious version well formulated by Cosmides and Tooby (e.g., Cosmides & Tooby 1987, Tooby & Cosmides 1992) —will succeed to the extent that it causes cognitive psychologists to rethink central aspects of human cognition in an evolutionary perspective, to the extent, that is, that psychology in general becomes evolutionary. The human species is exceptional by its massive investment in cognition, and in forms of cognitive activity—language, metarepresentation, abstract thinking—that are as unique to humans as echolocation is unique (...) to bats. The promise of evolutionary psychology is thus to help explain not just traits of human psychology that are homologous to those of many other species, but also traits of human psychology that are genuinely exceptional and that in turn help explain the exceptional character of human culture and ecology. However, most of the work done in evolutionary psychology so far is on aspects of human psychology that are not specifically human except in their details. Showing, for instance, how human preferences in mate choice are fine -tuned in the way the theory of evolution would predict is of great interest (see e.g., Buss 1994) but it can be done on the basis of a relatively shallow psychology. This makes work on distinctly human adaptations involving higher cognition of particular importance for defenders of a psychologically ambitious evolutionary psychology. What is often presented (e.g., Pinker, 1997) as the signal achievement of cognitive evolutionary psychology in this respect is the experimental testing of Cosmides’ (1989) hypothesis that there exists an evolved competence to deal with social contracts, and, in particular to detect cheaters. We want to argue that, because of faulty methodological choices—the quasi-exclusive reliance on the four-cards selection task—, the hypothesis has in fact not yet been tested. The plan of this chapter is as follows: We begin, with a short presentation of Cosmides’s social contract hypothesis, of Wason selection task, and of Cosmides’s reasons to use the task in order to test the theory..

The evolution of reciprocal altruism probably involved the evolution of mechanisms to detect cheating and remember cheaters. In a well-known study, Mealey, Daood, and Krage (1996) observed that participants had enhanced memory for faces that had previously been associated with descriptions of acts of cheating. There were, however, problems with the descriptions that were used in that study. We sought to replicate and extend the findings of Mealey and colleagues by using more controlled descriptions and by examining the possibility of (...) enhanced altruist recognition. We also examined whether individual differences in cheating tendencies were related to cheater and altruist recognition. In the first experiment, 164 undergraduates saw 40 faces that were paired with character descriptions representing the categories of cheater, trustworthy, altruist, or neutral, for individuals who had either low or high social status. One week later participants reported which faces they recognized from the previous week (among 80 faces). Overall, the results failed to replicate the findings of Mealey and her colleagues, as there was no enhanced memory for cheaters. In addition, there was no enhanced memory for altruists, and no effect of participants’ cheating tendencies. A second experiment using a slightly different methodology produced similar results, with some evidence for enhanced memory for altruists. (shrink)

Unified, all-purpose, philosophical models of reduction in science lack resources for capturing varieties of cross-scientific relations that have proven critical to understanding some scientific achievements. Not only do those models obscure the distinction between successional and cross-scientific relations, their preoccupations with the structures of both theories and things provide no means for accommodating the contributions to various sciences of theories and research about long-term diachronic processes involving large-scale, distributed systems. Darwin's theory of evolution by natural selection is the parade case. (...) Explanatory pluralism accommodates a wider range of connections between theories and inquiries in science than all-purpose models of reduction do. Consequently, it provides analytical tools for understanding the roles of the theoretical proposals about the evolution of the human mind/brain that have proliferated over the last two decades. Those proposals have testable implications pertaining to both structure and processing in the modern human mind/brain. An example of such research illustrates how those proposals and investigative tools and experiments cut across both explanatory levels and modes of analysis within the cognitive sciences and how those studies can yield evidence that bears on the assessment of competing theories and models.

Evolutionary psychology and intelligent‐design theory both need to be able to account for the empirical world, or the world as it is. This essay is an attempt to clarify the challenges these theories need to meet, if the relevant empirical findings are replicable. There is evidence of change in the biological world and of modularity of mind, and there is a growing body of work that finds evolutionary theory a convincing and fruitful account of the “design” of the mind. Three (...) major empirical findings within evolutionary psychology are presented and discussed. The author claims that Cartesian dualism, as it is usually meant within psychology—a split between body and mind—is false, but that Descartes' original division between body and soul has not been challenged and is not challenged by the evidence that the mind is also a biological entity. The article concludes that the convergence of theology and science is to be found in the onus to discover the truth about the world as it really is, and this calls for an ability on both parts to account for the empirical world.

What counts as human rationality: reasoning processes that embody content-independent formal theories, such as propositional logic, or reasoning processes that are well designed for solving important adaptive problems? Most theories of human reasoning have been based on content-independent formal rationality, whereas adaptive reasoning, ecological or evolutionary, has been little explored. We elaborate and test an evolutionary approach, Cosmides' social contract theory, using the Wason selection task. In the first part, we disentangle the theoretical concept of a “social contract” from that (...) of a “cheater-detection algorithm”. We demonstrate that the fact that a rule is perceived as a social contract — or a conditional permission or obligation, as Cheng and Holyoak proposed — is not sufficient to elicit Cosmides' striking results, which we replicated. The crucial issue is not semantic, but pragmatic: whether a person is cued into the perspective of a party who can be cheated. In the second part, we distinguish between social contracts with bilateral and unilateral cheating options. Perspective change in contracts with bilateral cheating options turns P & not-Q responses into not-P & Q responses. The results strongly support social contract theory, contradict availability theory, and cannot be accounted for by pragmatic reasoning schema theory, which lacks the pragmatic concepts of perspectives and cheating detection.

For some evolutionary psychology is merely a field of inquiry, but for others it is a robust paradigm involving specific theories about the nature and evolution of the human mind. Proponents of this paradigm claim to have made several important discoveries regarding the evolved architecture of the mind. Highly publicized discoveries include a cheater-detection module, a psychological sex difference in jealousy, and motivational mechanisms underlying parental love and its lapses, which purportedly result in child maltreatment. In this article, (...) I argue that the empirical evidence for these ‘discoveries’ is inconclusive, at best. I suggest that, as the reigning paradigm in evolutionary psychology has produced questionable results, the evolutionary study of human psychology is still in need of a guiding paradigm. (shrink)

A review of extent business ethics research uncovered well over 200 published articles that investigated the role of job functions within a business organization as an explanatory factor of ethical or unethical behavior. While an important body of work, ethical breaches are often found to cut across job functions and involve multiple disciplines embedded in a business organization. This research seeks to explore a crossfunctional explanation for ethical reasoning by using an instrument new to business ethics research, the Wason selection (...) task, but well-grounded and validated in cognitive research and evolutionary psychology, to assess an individual's ability to detect rule-based social contract violations. A sample of 276 full-time business practitioners, enrolled in part-time M.B.A. programs, from the accounting, finance, information technology, marketing, supply chain, and human resource management job functions were compared on their ability to detect rule violators across a series of production scenarios in the Wason selection task. Rates of cheater detection were calculated to determine if substantive differences existed across job functions. This was followed by a series of pairwise comparisons of percentages of cheater detection across the job functions using z-tests for assessing statistical significance. The data analysis showed differences in cheater detection, with most of the variance due to the marketing job function group. Insights from this study for scholars, educators, and practitioners in the business ethics field are discussed. (shrink)

The social exchange theory of reasoning, which is championed by Leda Cosmides and John Tooby, falls under the general rubric “evolutionary psychology” and asserts that human reasoning is governed by content-dependent, domain-specific, evolutionarily-derived algorithms. According to Cosmides and Tooby, the presumptive existence of what they call “cheater-detection” algorithms disconfirms the claim that we reason via general-purpose mechanisms or via inductively acquired principles. We contend that the Cosmides/Tooby arguments in favor of domain-specific algorithms or evolutionarily-derived mechanisms fail and that (...) the notion of a social exchange rule, which is central to their theory, is not correctly characterized. As a consequence, whether or not their conclusion is true cannot be established on the basis of the arguments they have presented. (shrink)

“Ought” cannot be derived from “is,” so why should facts about human nature be of interest to business ethicists? In this article, we discuss why the nature of human nature is relevant to anyone wishing to create a more just and humane workplace and society. We begin by presenting evolutionary psychology as a research framework, and then present three examples of research that illuminate various evolved cognitive programs. The first involves the cognitive foundations of trade, including a neurocognitive mechanism specialized (...) for a form of moral reasoning: cheater detection. The second involves the moral sentiments triggered by participating in collective actions, which are relevant to organizational behavior. The third involves the evolved programs whereby our minds socially construct groups, and how these can be harnessed to reduce racism and foster true diversity in the workplace. In each case, we discuss how what has been learned about these evolved programs might inform the study and practice of business ethics. (shrink)

This paper tests whether a person’s predominant level of moral reasoning has an effect on the ability to detect cheaters on conditional social contract rules. Itspecifically examines if principled reasoners are better at cheater detection on adapted versions of the Wason selection task. Results from my study do not support the hypothesis that cheater detection is influenced by a individual’s socio-moral perspective.

The theme for this volume is social cognition, construed from a psychological and collective point of view. From the psychological point of view, the question is to understand how the human mind processes social information; how it encodes, stores and uses it in the social context. From a collective point of view, the question is to understand how individual cognition is influenced (improved, increased or impaired) by social interactions, for instance in communicating and collaborating with intelligent agents. These two dimensions (...) of social cognition are obviously interdependent: the psychological dimension makes the collective dimension possible, which can in return modify the psychological dimension. The book is divided into four parts. The first part is about socio-cognitive skills. Among those, we count face recognition, imitation learning, embodied social interaction, cheater detection and psychological concept acquisition. The second part is about persons and memories: stereotypes, attraction judgements and impression formation are the subjects at hand. The third part is about understanding each other. A key part of that understanding is the motor system (whether or not we see it as a "mirror"), but community membership itself can also contribute to our understanding of others. The fourth and final part is about social cognition in societies. This section is unified by the common goal of understand how social cognition actually influences the structure of different societies, whether whole cultures, specific social networks, rural communities or even groups of caterpillars!

Perceptual processes, in particular modular processes, have long been understood as being mandatory. But exactly what mandatoriness amounts to is left to intuition. This paper identifies a crucial ambiguity in the notion of mandatoriness. Discussions of mandatory processes have run together notions of automaticity and ballisticity. Teasing apart these notions creates an important tool for the modularist's toolbox. Different putatively modular processes appear to differ in their kinds of mandatoriness. Separating out the automatic from the ballistic can help the modularist (...) diagnose and explain away some putative counterexamples to multimodal and central modules, thereby helping us to better evaluate the evidentiary status of modularity theory.

According to some psychological studies, women approaching ovulation feel the increased desire to have short-term sexual affairs with “sexy cads” while they are in long-term relations with “good dads.” I argue that this psychological property is a vestige of our evolutionary history. Early hominid females occasionally acquired good genes from top-ranking males while they were in long-term relations with low-ranking males. The Paleolithic living conditions indicate that women with the foregoing psychological trait were more likely to have viable children than (...) those without it. Sexy cads are the descendents of the top-ranking males, and good dads are the descendents of the low-ranking males. Sexy cads and good dads will continue to coexist in the future, developing better methods to detect cheaters and to escape detection. (shrink)

The idea that cheaters cannot (really) win in sports persists among philosophers, mainly due to the lingering influence of Bernard Suits’ logical incompatibility thesis. In this article I explain why the thesis does not apply to sports. I argue that the question whether cheating can be prohibited in sports is empirical rather than analytic, as is the case for games subject to the thesis. Thus, sports rules do not make cheating impossible and since game officials cannot always detect cheating and (...) punish cheaters, cheating is a part of sports and cheaters sometimes win. Even if advances in technology made it impossible for cheaters to evade detection, since in-game officials will never know whether their attempts to provide restorative justice to those victimized by acts of cheating are successful, and since cheaters exploit this fact, it follows that not only is cheating a part of sports, but it always will be.

Only a small proportion of academically dishonest students ever receive an official report of academic dishonesty, and the sociology of deviance literature is ripe with studies illustrating disproportionalities in detecting, policing, and prosecuting crimes. This study addresses the degree to which disproportionalities exist in the application of relatively few official sanctions levied upon students for academic dishonesty. I compared the demographics of those who have been reported for cheating with those of an entire undergraduate student body and of self-reported cheaters (...) in the literature. I found that international students are much more likely than domestic students to get reported. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:VIOLENT MEMES AND SUSPICIOUS MINDS: GIRARD'S SCAPEGOAT MECHANISM IN THE LIGHT OF EVOLUTION AND MEMETICS Guömundur Ingi Markússon Reykjavik, Iceland The present article is an attempt to bring mimetic theory into dialogue with certain evolutionary approaches to human culture, i.e., evolutionarypsychology and memetics. That which immediately suggests a consonance between these approaches is a shared concern for the fundamental aspects ofhuman culture, or "fundamental anthropology." My discussion aims at (...) reconsidering Girard's startling insight concerning the significance of scapegoating in the formation of human culture, ritual and myth—or, in short, his concept of the scapegoat mechanism. Two alternative approaches will be explored: (1) On the basis of evolutionary psychology, scapegoating is considered as a cognitive side-effect; (2) with reference to memetics, it is suggested that the scapegoat mechanism is a memetic parasite. The former account is an interpretation ofPascal Boyer's ideas about group mentality and fundamentalist violence in his recent book ReligionExplained(2001). The latter consideration is inspired byTerrence W. Deacon's concept of language evolution and symbolic reference in his book The Symbolic Species (1997). It should be emphasized at the outset that neither Boyer nor Deacon are concerned with scapegoating and, needless to say, the application and interpretation oftheir ideas is entirely my own. 1. The Scapegoat Mechanism as a Cognitive Side Effect The following is an attempt to formulate a cognitive account of scapegoating based on Pascal Boyer's ideas about fundamentalism (2001, 292ff). Guömundur Ingi Markússon89 1.1. The Coalitional Reasoning ofthe Social Mind Boyer's theory of religion is firmly rooted in evolutionary psychology (2001, 118, passim)} A key concept in evolutionary psychology is the environment ofevolutionary adapteäness (EEA) which is centered around the claim that our cognitive apparatus evolved in response to ecological problems faced by our ancestors in the Pleistocene period (which lasted from ca. 2 million-10,000 years ago). In other words, the cognition of modern humans is geared to the ancestral environments of our huntergatherer past. The key issue in evolutionary psychology is to gain insight into the adaptive problems faced by our ancestors, and figure out the necessary cognitive capabilities needed to solve them. The resulting models of how the mind works can then be tested experimentally. Evolutionary psychologists also emphasize the áomain specificity of our psychological mechanisms, i.e., in simple terms, that our mind is a collection of specialized mechanisms wrought by natural selection to deal with specific features of our environment, such as detecting predators, keeping track of social relations, etc. In Boyer's account, the mixed stock of our evolutionary heritage includes a complex array of psychological mechanisms for keeping track ofa wide spectrum ofsocial relations, the social mina (2001, 122). An essential aspect of our social intelligence is "intuitive psychology" or a "theory of mind," i.e., seeing others as intentional agents, realizing what they are up to, what their beliefs and desires are, being able to predict their behavior, etc. According to evolutionary psychologists we are adapted for social exchange. We easily calculate the costs and benefits of our interactions with others. Experiments have shown that logical problems are much more transparent to people when presented as social exchange problems. In such cases, the logical rule in question is restated as a "check for cheaters" rule, i.e., the problem is to figure out whether people respect social conventions or not. Evolutionary psychologists interpretthese results to the effect that our cognition is geared to evaluate social exchange, and we have evolved a disposition to check for cheaters in social exchange situations (2001, 124f; Cosmides 1989; Cosmides & Tooby 1992).2 1 On evolutionary psychology, see Barkow et al. and Laland and Brown (ch. 5). 2 Cosmides, one of the pioneers of evolutionary psychology, characterizes "check for cheaters" thus: "cheating can be defined as the violation of a rule established, explicitly or implicitly, by acceptance ofa social contract. A social contract relatesperceived benefits to 90Violent Mêmes and Suspicious Minds Evaluation oftrust is essential to human interaction: "That humans depend on cooperation creates strategic problems, where the value (the expected benefit) of a particular move depends on whether someone else makes a particular move...."

I argue that in purely professional games of pure chance, such as slot machines, roulette, baccarat or pachinko, any instance of cheating that successfully deceives the judge can be ‘part of the game’. I examine, and reject, various proposals for the ‘ethos’ that determines how we ought to interpret the formal rules of games of pure chance, such as being a test of skill, a matter of entertainment, a display of aesthetic beauty, an opportunity for hedonistic pleasure, and a fraternal (...) activity. Ultimately, I argue that ‘winning the benefit’ is the only ethos that can apply in purely professional games of pure chance, and that if we interpret the formal rules according to this ethos, cheating that is undertaken with respect for the judge’s authority, but that attempts to cause the judge of the game to ‘voluntarily’ relinquish the benefit of the game by deceiving them into thinking that the formal rules of the game have been followed, is impermissible but acceptable cheating, and is therefore within, rather than outside, the game. Here, I define ‘games of pure chance’ as games in which chance is the only determinant of winning. (shrink)

Numerous academic studies and reports indicate that as many as half of all students cheat on exams. Cheating on exams undermines the central purpose of a university, corrupts the meaning of grades as a measure of subject matter mastery, and significantly harms honest students. Although instructors are aware that many students cheat and they clearly oppose the behavior, they do little to punish cheaters. Accusing, prosecuting and convicting cheaters are time intensive, stressful and potentially costly activities for which faculty members (...) receive few rewards. In this paper, we derive an equation to estimate the benefit that can be gained by a student who copies on a multiple choice exam. We then propose an exam design that not only eliminates the benefit, but also proportionately punishes cheaters, with little to no cost to instructors. Moreover, the exam system we propose can allow an instructor to determine, with a high degree of certainty, the odds that any student seated anywhere in the classroom cheated on any part of the exam.

Students display resistance in the classroom in numerous ways, often in the form of academic misconduct. Some argue that resistance can reflect cleverness and creativity, rather than apathy. This investigation aimed to develop a psychometric tool to examine classroom resistance as well as identify individual and situational determinants of the same. Data from 853 participants was collected on measures of resistance behaviors in educational contexts and their environmental contributors, creativity, personality, and deception. Further, participants indicated their frequency of resistance across (...) two time periods: kindergarten through middle school, and high school through college. Exploratory and confirmatory factor analyses identified a robust three-factor structure for the Classroom Resistance Scale, comprising Test-Oriented Cheating, Blatant Academic Dishonesty, and Unethical Shortcuts. The person-situation analysis indicated that students who engaged in resistance shared some consistent characteristics: they were more likely to be closed to new experiences, unimaginative, more extraverted, and highly influenced by their peers. Moreover, the frequency of classroom resistance increased in higher grades as compared to lower ones. Implications of spillover effects of academic dishonesty into the workplace are discussed, in addition to suggestions for future research. (shrink)

In the Frank (1988) model, a small increase in the number of cheaters will soon be reversed. It is not clear that this prediction holds for sociopathy. There are also many attractive evolutionary models that do not admit a small, stable proportion of cheaters. Hence, without definitive evidence about the character of early human society, we cannot conclude that sociopathy has an evolutionary origin.

Despite Protagoras’ infamous reputation for corrupting his students, his “Great Speech” (Plato, Protagoras 320c-328d) presents one of the most important arguments in the history of ethics. Refuting Socrates’ contention that virtue must be unteachable since even the best of men cannot raise good children, Protagoras argues that everyone is capable of learning the difference between right and wrong.

This article explores accusations as collaboratively accomplished in classroom peer interactions in the absence of a teacher. The analysis shows how the children use local classroom rules and teacher authority as resources and warrants to invoke multi-layered moral orders and identities, and hold one child accountable through accusations about their behavior.

This article argues that understanding children’s accusations requires understanding of how such interactions (...) compose and reflect the school context that is co-produced through the implementation of accountable ways in which to behave.

In the automatic detection of epileptic seizures, the monitoring of critically ill patients with time varying EEG signals is an essential procedure in intensive care units. There is an increasing interest in using EEG analysis to detect seizure, and in this study we aim to get a better understanding of how to visualize the information in the EEG time-frequency feature, and design and train a novel random forest algorithm for EEG decoding, especially for multiple-levels of illness. Here, we propose (...) an automatic detection framework for epileptic seizure based on multiple time-frequency analysis approaches; it involves a novel random forest model combined with grid search optimization. The short-time Fourier transformation visualizes seizure features after normalization. The dimensionality of features is reduced through principal component analysis before feeding them into the classification model. The training parameters are optimized using grid search optimization to improve detection performance and diagnostic accuracy by in the recognition of three different levels epileptic of conditions (healthy subjects, seizure-free intervals, seizure activity). Our proposed model was used to classify 500 samples of raw EEG data, and multiple cross-validations were adopted to boost the modeling accuracy. Experimental results were evaluated by an accuracy, a confusion matrix, a receiver operating characteristic curve and an area under the curve. The evaluations indicated that our model achieved the more effective classification than some previous typical methods. Such a scheme for computer-assisted clinical diagnosis of seizures has a potential guiding significance, which not only relieves the suffering of patient with epilepsy to improve quality of life, but also helps neurologists reduce their workload.

Detecting contract cheating in written submissions can be difficult beyond direct plagiarism detectable via technology. Successfully identifying potential cases of contract cheating in written work such as essays and reports is largely dependent on the experience of assessors and knowledge of student. It is further dependent on their familiarity with the patterns and clues evident in sections of body text and reference materials to identify irregularities. Consequently, some knowledge of what the patterns and clues look like is required. This paper (...) documents how to identify some of the patterns and clues observed in essay and report submissions. Effective assessment design with specific contextual requirements make irregularities easier to detect and interpret. The irregularities identified were confirmed as instances of contract cheating through conversations held with postgraduate students. An essential element of the conversations was the evidence presented for discussion. Irregularities were noted on a pro-forma specifically developed for this purpose. Patterns identified include misrepresented bibliographic data, inappropriate references, irrelevant material and generalised text that did not address the assessment question or grading criteria. The validated patterns formed the basis of identifying potential instances of contract cheating in later submissions. Timely conversations with students before the end of semester are essential to determining whether the patterns and clues link to poor knowledge of academic writing conventions or classified as contract cheating necessitating the application of appropriate penalties under institutional policies and procedures.

Five aspects of visual change detection are reviewed. The first concerns the concept of change itself, in particular the ways it differs from the related notions of motion and difference. The second involves the various methodological approaches that have been developed to study change detection; it is shown that under a variety of conditions observers are often unable to see large changes directly in their field of view. Next, it is argued that this “change blindness” indicates that focused (...) attention is needed to detect change, and that this can help map out the nature of visual attention. The fourth aspect concerns how these results affect our understanding of visual perception—for example, the implication that a sparse, dynamic representation underlies much of our visual experience. Finally, a brief discussion is presented concerning the limits to our current understanding of change detection. (shrink)

Can managers detect honest people’s lies in a handwritten message? In this article, I will briefly discuss graphology and a basic model of interpersonal communication. I will then develop a fundamental theoretical framework of eight principles for detecting lies based on the basic communication model, handwriting analyses, and the following assumptions: For most people, it is easier to tell the truth than to tell lies. This applies to handwritings also. When most honest people lie, they try to hide their stressful (...) emotions in the encoding process. As a consequence, they deviate from their own normal writing and violate their own personal moral standards. Interestingly enough, the art or science of detecting a lie in a handwritten sample is to focus not on what they write, but on how they write it. These 24 exhibits (cases) written in 11 languages—used in different parts of the world—help managers apply this important theoretical framework of interpersonal communication, understand the encoding process, pinpoint these sudden emotional changes, decode handwritten messages, unlock the secrets, reveal the message’s true meanings, and detect people’s lies.

Purpose The online economy has not resolved the issue of racial bias in its applications. While algorithms are procedures that facilitate automated decision-making, or a sequence of unambiguous instructions, bias is a byproduct of these computations, bringing harm to historically disadvantaged populations. This paper argues that algorithmic biases explicitly and implicitly harm racial groups and lead to forms of discrimination. Relying upon sociological and technical research, the paper offers commentary on the need for more workplace diversity within high-tech industries and (...) public policies that can detect or reduce the likelihood of racial bias in algorithmic design and execution. Design/methodology/approach The paper shares examples in the US where algorithmic biases have been reported and the strategies for explaining and addressing them. Findings The findings of the paper suggest that explicit racial bias in algorithms can be mitigated by existing laws, including those governing housing, employment, and the extension of credit. Implicit, or unconscious, biases are harder to redress without more diverse workplaces and public policies that have an approach to bias detection and mitigation. Research limitations/implications The major implication of this research is that further research needs to be done. Increasing the scholarly research in this area will be a major contribution in understanding how emerging technologies are creating disparate and unfair treatment for certain populations. Practical implications The practical implications of the work point to areas within industries and the government that can tackle the question of algorithmic bias, fairness and accountability, especially African-Americans. Social implications The social implications are that emerging technologies are not devoid of societal influences that constantly define positions of power, values, and norms. Originality/value The paper joins a scarcity of existing research, especially in the area that intersects race and algorithmic development. (shrink)

The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s (...) prediction are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

Block [Block, N. . Two neural correlates of consciousness. Trends in Cognitive Science, 9, 46–52] and Snodgrass claim that a signal detection theory analysis of qualitative difference paradigms, in particular the exclusion failure paradigm, reveals cases of phenomenal consciousness without access consciousness. This claim is unwarranted on several grounds. First, partial cognitive access rather than a total lack of cognitive access can account for exclusion failure results. Second, Snodgrass’s Objective Threshold/Strategic model of perception relies on a problematic ‘enable’ approach (...) to perception that denies the possibility of intentional control of unconscious perception and any effect of following different task instructions on the presence/absence of phenomenal consciousness. Many of Block’s purported examples of phenomenal consciousness without cognitive access also rely on this problematic approach. Third, qualitative difference paradigms may index only a subset of access consciousness. Thus, qualitative difference paradigms like exclusion failure cannot be used to isolate phenomenal consciousness, any attempt to do so still faces serious methodological problems. (shrink)

In this paper my concern is with the collective moral responsibility of criminal investigators for the outcomes of their investigations, bearing in mind that it is important to distinguish collective moral responsibility from, and relate it to, individual moral responsibility. In what sense, if any, are police detectives individually and collectively morally responsible for their success (or, for that matter, their failure) in gathering sufficient evidence to identify, arrest, and charge an offender who has committed a serious crime? Alternatively, in (...) what sense are they morally responsible in cases where they identify, arrest, and charge an innocent person? And in what sense, if any, are police detectives individually and collectively morally responsible for the ultimate outcome of the trial, the finding by the courts of someone they have investigated and charged with a serious crime to be guilty or innocent?

A large part of technological advances, especially in the field of industry, have been focused on the optimization of productive processes. However, the detection of anomalies has turned out to be a great challenge in fields like industry, medicine or stock markets. The present work addresses anomaly detection on a control level plant. We propose the application of different intelligent techniques, which allow to obtain one-class classifiers using real data taken from the correct plant operation. The performance of (...) each classifier is assessed and validated with real created faults, achieving successful overall results. (shrink)

The safety and stability of the power supply system are affected by some faults that often occur in power system. To solve this problem, a criterion algorithm based on the chaotic neural network and a fault detection algorithm based on discrete wavelet transform are proposed in this paper. MATLAB/Simulink is used to establish the system model to output fault signals and travelling wave signals. Db4 wavelet decomposes the travelling wave signals into detail signals and approximate signals, and these signals (...) are combined with the two-terminal travelling wave location method to achieve fault location. And the wavelet detail coefficients are extracted to input to the proposed chaotic neural network. The results show that the criterion algorithm can effectively determine whether there are faults in the power system, the fault detection algorithm has the capabilities of locating the system faults accurately, and both algorithms are not affected by fault type, fault location, fault initial angle, and transition resistance.

Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) (...) which is, to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

We present a taxonomy of errors in the scientific literature and an account of how the errors are distributed over the categories. We have developed the taxonomy by studying substantial errors in the scientific literature as described in retraction notices published in the journal Science over the past 35 years. We then examine how the sorts of errors that lead to retracted papers can be prevented and detected, considering the perspective of collaborating scientists, journal editors and referees, and readers of (...) the published articles.

Threshold- and signal-detection-based models have dominated theorizing about recognition memory. Building upon these theoretical frameworks, we have argued for a dual-process model in which conscious recollection and familiarity contribute to memory performance. In the current paper we assessed several memory models by examining the effects of levels of processing and the number of presentations on recognition memory receiver operating characteristics . In general, when the ROCs were plotted in probability space they exhibited an inverted U shape; however, when they (...) were plotted inzspace they exhibited a U shape. An examination of the ROCs showed that the dual-process model could account for the observed ROCs, but that models based solely on either threshold or signal-detection processes failed to provide a sufficient account of the data. Furthermore, an examination of subjects' introspective reports using the remember/know procedure showed that subjects were aware of recollection and familiarity and were able to consistently report on their occurrence. The remember/know data were used to accurately predict the shapes of the ROCs, and estimates of recollection and familiarity derived from the ROC data mirrored the subjective reports of these processes.
