American Academy of Pediatrics (AAP) and American College of Medical Genetics (ACMG) recently provided two recommendations about predictive genetic testing of children. The Clinical Sequencing Exploratory Research Consortium's Pediatrics Working Group compared these recommendations, focusing on operational and ethical issues specific to decision making for children. Content analysis of the statements addresses two issues: (1) how these recommendations characterize and analyze locus of decision making, as well as the risks and benefits of testing, and (2) whether the guidelines conflict (...) or come to different but compatible conclusions because they consider different testing scenarios. These statements differ in ethically significant ways. AAP/ACMG analyzes risks and benefits using best interests of the child and recommends that, absent ameliorative interventions available during childhood, clinicians should generally decline to order testing. Parents authorize focused tests. ACMG analyzes risks and benefits using the interests of the child and other family members and recommends that sequencing results be examined for additional variants that can lead to ameliorative interventions, regardless of age, which laboratories should report to clinicians who should contextualize the results. Parents must accept additional analysis. The ethical arguments in these statements appear to be in tension with each other. (shrink)

The prospect of using genome technologies to modify the human germline has raised profound moral disagreement but also emphasizes the need for wide-ranging discussion and a well-informed policy response. The Hinxton Group brought together scientists, ethicists, policymakers, and journal editors for an international, interdisciplinary meeting on this subject. This consensus statement formulated by the group calls for support of genome editing research and the development of a scientific roadmap for safety and efficacy; recognizes the ethical challenges involved in (...) clinical reproductive applications of genome editing but, importantly, rejects the idea that human reproductive germline modification is necessarily morally unacceptable; and highlights the importance of meaningful engagement in discussions of genome editing and the development of regulation and oversight mechanisms to govern future uses of such technologies.

Simple Heuristics That Make Us Smart invites readers to embark on a new journey into a land of rationality that differs from the familiar territory of cognitive science and economics. Traditional views of rationality tend to see decision makers as possessing superhuman powers of reason, limitless knowledge, and all of eternity in which to ponder choices. To understand decisions in the real world, we need a different, more psychologically plausible notion of rationality, and this book provides it. It is about (...) fast and frugal heuristics--simple rules for making decisions when time is pressing and deep thought an unaffordable luxury. These heuristics can enable both living organisms and artificial systems to make smart choices, classifications, and predictions by employing bounded rationality. But when and how can such fast and frugal heuristics work? Can judgments based simply on one good reason be as accurate as those based on many reasons? Could less knowledge even lead to systematically better predictions than more knowledge? Simple Heuristics explores these questions, developing computational models of heuristics and testing them through experiments and analyses. It shows how fast and frugal heuristics can produce adaptive decisions in situations as varied as choosing a mate, dividing resources among offspring, predicting high school drop out rates, and playing the stock market. As an interdisciplinary work that is both useful and engaging, this book will appeal to a wide audience. It is ideal for researchers in cognitive psychology, evolutionary psychology, and cognitive science, as well as in economics and artificial intelligence. It will also inspire anyone interested in simply making good decisions. (shrink)

This composition text focuses on argument and persuasion using examples, exercises, readings, and writing assignments. The text guides students through developing a thesis, finding and organizing evidence, and writing and revising several different types of argumentative papers. The second edition de-emphasizes the language of formal logic, and all the readings, examples, and exercises have been updated. Additional coverage has been given to refutation. Widely used in both advanced composition and second semester freshman courses.

Individual character strengths have been increasingly valued, as they facilitate social functioning, well-being, and performance. However, little is known about how individuals use their strengths for important but distinct goals including task accomplishment and relationship maintenance in organizations. The purpose of this study is to develop and validate a Strengths Use Scale that can be used to measure the use of strengths for tasks and relationships in the workplace. For this purpose, we used the exploratory mixed-method design and conducted a (...) series of studies. In Study 1, we conducted an exploratory factor analysis to ensure the construct validity of the Strengths Use Scale on a sample of 187 employees. We found that the scale comprises two dimensions: strengths use for tasks and strengths use for relationships. In Study 2a, we verified the two-factor structure of the Strengths Use Scale using the confirmatory factor analysis on a separate sample of 213 employees. The results of Study 2b demonstrated that the scale has good measurement invariance across gender and age groups, on the sample of 205 employees. Moreover, strengths use for tasks and strengths use for relationships positively correlated with well-being and work engagement and negatively correlated with turnover intention, supporting the criterion-related validity of the scale. In Study 3, a test–retest reliability analysis with a sample of 94 employees indicated that the scale has high reliability. Theoretical and practical implications of the findings are discussed.

This study aimed to evaluate if eye blinks can be used to discriminate players with different performance in a session of Nintendo Entertainment System (NES) Tetris. To that end, we developed a state-of-the-art method for blink extraction from EAR measures, which is robust enough to be used with data collected by a low-grade webcam such as the ones widely available on laptop computers. Our results show a significant decrease in blink rate per minute (blinks/m) during the first minute of playing (...) Tetris. After having defined 3 groups of proficiency based on in-game performance (Novices, Intermediates, and Experts) we found out that expert players display a significantly lower decrease in blinks/m compared to novices during the first minute of gameplay, which shows that Tetris players' proficiency can be detected by looking at eye blinks/m variations during the early phase of a game session. This difference in blinks/m is observed throughout the entire game session, which supports the general conclusion that proficient Tetris players have a lower decrease in blinks/m, even when playing more difficult levels. Finally, we offer some interpretations of this effect and the relationship that our results may have with the visual cognitive workload experienced during the gameplay. (shrink)

While understanding and expressing causal relations are universal aspects of human cognition, language users may differ in their capacity to perceive, interpret, and express events. One source of variation in descriptions of caused motion events is agentivity, which refers to the attribution of a result to the agent's action. Depending on the perspective taken, the same event may be described with agentive or non-agentive interpretations. Does language play a role in how people construe and express caused motion events? The present (...) study investigated the use of agentive vs. non-agentive language by speakers of different languages (i.e., monolingual speakers of English and Korean, and Korean learners of English). All three groups described prototypical causal events similarly, using agentive language (active transitive sentences). However, when it came to non-prototypical causal events (where the agent was not shown in the scene), they diverged in their choice of language: English speakers favored agentive language (passive transitive sentences), whereas Korean speakers preferred non-agentive language (intransitive sentences). Korean learners of English patterned with Korean speakers, demonstrating L1 influence on their use of English. These findings highlight the effects of language on motion event construal. (shrink)

We routinely need to process the identity of many faces around us, and how the brain achieves this is still the subject of much research in cognitive neuroscience. To date, insights on face identity processing have come from both healthy and clinical populations. However, in order to directly compare results across and within participant groups, and across different studies, it is crucial that a standard task is utilised which includes different exemplars (for example, non-face stimuli along with faces), is memory-neutral, (...) and taps into identity recognition across orientation and across viewpoint change. The goal of this study was to test a previously behaviourally tested, optimised face and object identity matching design in a healthy control sample whilst being scanned using fMRI. Specifically, we investigated categorical, orientation, and category-specific orientation effects while participants were focused on identity processing of simultaneously presented exemplar stimuli. Alongside observing category and orientation specific effects in a distributed set of brain regions, we also saw an interaction between stimulus category and orientation in the bilateral fusiform gyrus and bilateral middle occipital gyrus. Generally these clusters showed the pattern of a heightened response to inverted, as opposed to upright faces; and to upright, as opposed to inverted shoes. These results are discussed in relation to previous studies and to potential future research within prosopagnosic individuals. (shrink)

Drawing on Moreno's cognitive-affective theory of learning with media, this research aims to investigate the effectiveness of different multimedia glosses on learners' vocabulary acquisition and reading comprehension in a CALL environment. A total of 160 university students who learnt English as a foreign language in four classes participated in the study and were exposed to one of the four conditions: L2 definition only, L2 definition coupled with audio, L2 definition plus video, and L2 definition with picture. Participants were asked to (...) read eight hypermediated reading texts. Reading comprehension as well as vocabulary acquisition were measured using a pretest–posttest design. The results show first that all these four conditions led to students' vocabulary gains. More specifically, participants who had access to L2 definition plus picture and plus videos achieved significantly higher scores than the other two groups, L2 definition coupled with audio and L2 definition only. Concerning reading comprehension, all multimedia glossing presentation led to better reading comprehension, but no differences were found among all the glossing groups. The questionnaire and interview data indicate that students preferred L2 definition coupled with video and picture glosses, followed by audio and L2 definition only. The results reflect that multimedia glossing presentation creates a different effect on students' vocabulary acquisition and reading comprehension, respectively. They also provide pedagogical implications for learning in times of COVID-19. (shrink)

Goldstein and Gigerenzer (2002) [Models of ecological rationality: The recognition heuristic. Psychological Review, 109 (1), 75–90] found evidence for the use of the recognition heuristic. For example, if an individual recognizes only one of two cities, they tend to infer that the recognized city has a larger population. A prediction that follows is that of the less‐is‐more effect: Recognizing fewer cities leads, under certain conditions, to more accurate inferences than recognizing more cities. We extend the recognition heuristic to group (...) decision‐making by developing majority and lexicographic models of how recognition information is used by groups. We formally show when the less‐is‐more effect is predicted in groups and we present a study where three‐member groups performed the population comparison task. Several aspects of our data indicate that members who can use the recognition heuristic are, not in all but in most cases, more influential in the group decision process than members who cannot use the heuristic. We also observed the less‐is‐more effect and found that models assuming that members who can use the recognition heuristic are more influential better predict when the effect occurs. (shrink)

Recently, novel lines of research have developed to study the influence of identity processes in sport-related behaviours. Yet, whereas emotions in sport are the result of a complex psychosocial process, little attention has been paid to examining the mechanisms that underlie how group membership influences athletes’ emotional experiences. The present narrative review aims at complementing the comprehensive review produced by Rees et al. (2015) on social identity in sport by reporting specific work on identity-based emotions in sport. To that (...) end, we firstly overview the different terminology currently used in the field of emotions in groups to clarify the distinct nature of emotions that result from an individual’s social identity. Secondly, we discuss key concepts of social identity to better understand the mechanisms underlying identity-based emotions. Thirdly, we address existing knowledge on identity-based emotions in sport. We close the present narrative review by suggesting future research perspectives based on existing meta-theories of social identity. Evidence from the social psychology literature is discussed alongside existing works from the sport literature to propose a crucial theoretical approach to better understand emotions in sport.

Applying the framework of ecological rationality, the authors studied the adaptivity of group decision making. In detail, they investigated whether groups apply decision strategies conditional on their composition in terms of task‐relevant features. The authors focused on the recognition heuristic, so the task‐relevant features were the validity of the group members' recognition and knowledge, which influenced the potential performance of group strategies. Forty‐three three‐member groups performed an inference task in which they had to infer which of two (...) German companies had the higher market capitalization. Results based on the choice data support the hypothesis that groups adaptively apply the strategy that leads to the highest theoretically achievable performance. Time constraints had no effect on strategy use but did have an effect on the proportions of different types of arguments. Possible mechanisms underlying the adaptive use of recognition in group decision making are discussed. (shrink)

We use discourse analysis to examine a group supervision meeting in which graduate students who are training to become school counselors discuss counseling experiences that they had at local high schools. Focusing on metadiscourse, or talk about talk, we integrate Ochs’ concepts of epistemic stance and affective stance and Tannen’s discussion of linguistic strategies as ambiguous and polysemous in terms of power and solidarity in order to demonstrate how counselors-in-training construct their identities as what Woodside et al. call ‘boundary-dwellers’ (...) in their professional community of practice. Examination of metadiscourse regarding address terms and the speech act of asking questions – and in particular highlighting how participants use negatively valenced affect words, the verb feel, and what Tannen calls ‘constructed dialogue’ – reveals their stances of uncertainty and discomfort, their transitional professional identities as entailing an uneasy navigation of relationships, and their recognition of the pivotal role of language in the process.

Our work supports synchronization for binding within Phillips & Singer's “contextual field” (CF) as well as the type of its lateral interaction they propose. Both firmly agree with our “association field” (AF) and its modulatory influences (Eckhorn et al. 1990). However, the CF connections seem to produce anticorrelation among assemblies representing unrelated structures, whereas experimental evidence indicates decoupling. Finally, it is unclear how the cortex can have access to the logistic function used in the “coherent infomax” approach.

This paper focuses on doctoral research which explored relationships and interpersonal learning through group dramatherapy and creative interviewing with adolescents in special education. A constructivist grounded theory study, positioning adolescents with intellectual/developmental disabilities as experts of their own relational experiences, revealed a tendency to “copy others.” The final grounded theory presented “copying” as a tool which participants consciously employed “to play with,” “learn from,” and “join in with” others. Commonly experiencing social ostracism, participants reflected awareness of their tendency to (...) “copy others” being underpinned by a need to belong. Belonging was therefore expressed as the ultimate therapeutic experience participants wished to have. Participant responses which link dramatic imitation to a self-identified tendency “to copy,” are discussed with regard to how imitation provides an accessible point of dramatic entry from which adolescents in special education begin to explore new ways of being and inter-relating. Recommendations for how dramatherapists might centralize imitative aspects of the dramatic process to achieve therapeutic intent when working alongside adolescents in special education are discussed with specific focus on creating a space of belonging.Note on type: Participant quotes extracted from the data are included throughout this article. In order to highlight participant’s contributions quotes are italicized and presented within speech marks. (shrink)

Three studies examined how members of a national group react to in-group wrongdoings. We expected that perceived in-group moral superiority would lead to unwillingness to repair the aggression. We also expected that internal-focused emotions such as group-based guilt and group-based shame would predict specific, misdeed-related reparative intentions but not general approach motivation toward the victim groups. In Study 1, facing the in-group’s recent aggression, participants who believed that the Hungarians have been more moral throughout (...) their history than members of other nations, used more exonerating cognitions, experienced less in-group critical emotions and showed less willingness to provide reparations for the members of the victim group. Study 2 and Study 3 confirmed most findings of Study 1. Perceived in-group moral superiority directly or indirectly reduced willingness to provide either general or specific reparations, while internally focused in-group critical emotions predicted specific misdeed-related reparative intentions but not general approach motivation. The role of emotional attachment to the in-group is considered. (shrink)

This paper presents a theory and computational model of the role of emotions in group decision making. After reviewing the role of emotions in individual decision making, it describes social and psychological mechanisms by which emotional and other information is transmitted between individuals. The processes by which these mechanisms can contribute to group consensus are modeled computationally using a program, HOTCO 3, which has been used to simulate simple cases of emotion-based group decision making.

Reflective processing is a joint social action that develops in interaction. Using conversation analysis and discursive psychology, this article focuses on self-reflective turns of talk in group counselling for adults at risk of type 2 diabetes. We show how reflective processing unfolds in patterns of interaction, wherein group members take an observing, evaluating or interpreting position towards their own actions and experiences. Self-reflective talk is neither exclusively dependent on counsellors’ actions nor limited to the niches the counselling programme (...) structure offers. Self-reflective talk is one method of generating joint reflective processing. Such talk makes a topic available for discussion by connecting details of counselling with individuals’ experiences and enabling sharing. Self-reflective talk thus serves as a way for group members to participate in constructing a lifestyle problem, to invite or provide sharing of experiences and to display their orientation to the institutional task at hand.

Moral foundations research suggests that liberals care about moral values related to individual rights such as harm and fairness, while conservatives care about those foundations in addition to caring more about group rights such as loyalty, authority, and purity. However, the question remains about how conservatives and liberals differ in relation to group-level moral principles. We used two versions of the moral foundations questionnaire with the target group being either abstract or specific ingroups or outgroups. Across three (...) studies, we observed that liberals showed more endorsement of Individualizing foundations with an outgroup target, while conservatives showed more endorsement of Binding foundations with an ingroup target. This general pattern was found when the framed, target-group was abstract and when target groups were specified about a general British-ingroup and an immigrant-outgroup. In Studies 2 and 3, both Individualizing-Ingroup Preference and Binding-Ingroup Preference scores predicted more Attitude Bias and more Negative Attitude Bias toward immigrants, more Implicit Bias, and more Perceived Threat from immigrants. We also demonstrated that increasing liberalism was associated with less Attitude Bias and less Negative Bias toward immigrants, less Implicit Bias, and less Perceived Threat from immigrants. Outgroup-individualizing foundations and Ingroup-Binding foundations showed different patterns of mediation of these effects. (shrink)

Acting as part of a corporation may allow an individual more easily to rationalize participating in a harmful act, but there are countervailing forces in corporate action that increase moral oversight and accountability. Making use of group agency to explain membership as a special feature of some corporate agents, I argue that when someone becomes a member of an organized group like a company, their own moral responsibility becomes entangled with the decisions of other members of the company, (...) whether or not they intend this effect. This moral entanglement in corporate decision-making explains why individuals have a moral obligation to act in their role as a corporate officer when they would not have an obligation to act in a personal capacity even if they had identical knowledge. The entanglement affects the individual’s own moral status and the moral status of the company itself. Moral entanglement of corporate decision-makers provides a principled explanation for a rule that is present in corporate criminal law that corporate officers with knowledge that another employee is about to commit a crime must actively intervene, and cannot rely on their status as bystanders.

This study investigates the ethnic differentials in contraceptive use in the north-eastern Ch’orti area of Guatemala, a region dominated by the Ladino culture. Data come from a household survey and in-depth interviews with service providers carried out in 2001 in the town of Jocotán, and a survey carried out in 1994 in two nearby indigenous villages (aldeas). Descriptive analysis and logistic regression are used to explore the data. Previous DHS surveys have used dress and language to classify ethnic groups. In (...) this paper, an alternative approach based on self-identification is adopted. The results reveal significant differences in contraceptive behaviour among different ethnic groups within the same town and region. The results show that self-identified Ladino women who represented the minority of the population had contraceptive behaviour similar to their counterparts elsewhere in Latin America. The extremely low levels of contraceptive use among indigenous women from the aldeas suggest that the corresponding DHS figures in this region are probably overestimated. (shrink)

I address the controversy in evolutionary biology concerning which levels of biological entity (units) can and do undergo natural selection. I refine a definition of the unit of selection, first presented by William Wimsatt, that is grounded in the structure of natural selection models. I examine Elliott Sober's objection to this structural definition, the "homogeneous populations" problem; I find that neither the proposed definition nor Sober's own causal account can solve the problem. Sober, in his solution using his causal view, (...) imports precisely the information needed to make the structural definition effective. Finally, I indicate how the proposed definition can clarify which sorts of evidence could be brought to bear on the controversial case of the Myxoma virus. (shrink)

This paper reports a literature review on the topic of ethical issues in in-depth interviews. The review returned three types of article: general discussion, issues in particular studies, and studies of interview-based research ethics. Whilst many of the issues discussed in these articles are generic to research ethics, such as confidentiality, they often had particular manifestations in this type of research. For example, privacy was a significant problem as interviews sometimes probe unexpected areas. For similar reasons, it is difficult to (...) give full information of the nature of a particular interview at the outset, hence informed consent is problematic. Where a pair is interviewed (such as carer and cared-for) there are major difficulties in maintaining confidentiality and protecting privacy. The potential for interviews to harm participants emotionally is noted in some papers, although this is often set against potential therapeutic benefit. As well as these generic issues, there are some ethical issues fairly specific to in-depth interviews. The problem of dual role is noted in many papers. It can take many forms: an interviewer might be nurse and researcher, scientist and counsellor, or reporter and evangelist. There are other specific issues such as taking sides in an interview, and protecting vulnerable groups. Little specific study of the ethics of in-depth interviews has taken place. However, that which has shows some important findings. For example, one study shows participants are not averse to discussing painful issues provided they feel the study is worthwhile. Some papers make recommendations for researchers. One such is that they should consider using a model of continuous (or process) consent rather than viewing consent as occurring once, at signature, prior to the interview. However, there is a need for further study of this area, both philosophical and empirical. (shrink)

The use of focus groups is a well‐established qualitative research method in the social sciences that would seem to offer scope for a significant contribution to the advancement of knowledge and understanding in the field of business ethics. This paper explores the potential contribution of focus groups, reviews their contribution to date and makes some recommendations regarding their future use. We find that, while the use of focus groups is not extensive, they have been utilised in a non‐negligible number of (...) studies. Focus groups are usually used as a supplementary method, often as part of the development of a research instrument. Whether used on their own or in conjunction with other methods, we find that in the majority of cases there is insufficient information for a reader to judge that the method has been carried out well and hence that the ‘findings’ may be trusted. Nor is it easy for future researchers to learn about the practical application of the method in business ethics contexts. We therefore recommend improved reporting in future published studies. Based on an analysis of a subsample of papers that provided a reasonable level of methodological detail, we provide further insights into, and recommendations for, the use of focus groups in business ethics research.

To be relevant to the constantly changing work patterns of the real world, effective learning in universities often occurs in small groups facilitated by collaborative environments where participants are dynamically involved in purposeful activities. The research described in this paper is an investigation of purposeful group work devised for experiential learning where a variety of socio-technical tools were used to support asynchronous tasks and communication among the learners. In order to explore the complexity of this collaborative activity a distinctive (...) inductive research approach has been adopted using reflective developmental methods. The data collection and the analysis part of the research involved the reflection of participants on their activity being requested as reports within their course work. Student reports were subject to content analysis using a computer-based tool that creates a conceptual map of collections of documents comparing the ratings and relationships of concepts among different sets of participants. The study was enhanced by the use of Q-methodology that allows the participants to outline their views and to make individual decisions on the relative importance that they place upon the available views of the larger group. Concepts from Activity Theory allowed the researchers to take a holistic contextual approach both to the design of the research and the interpretation of the findings to make some sense of the complexity of the dynamic work-learning dialectic in a socio-technical collaborative setting.

The Alperin-Goldschmidt Fusion Theorem [1, 5], when combined with pushing up [7], was a useful tool in the classification of the finite simple groups. Similar theorems are needed in the study of simple groups of finite Morley rank, in the even type case (that is, when the Sylow 2-subgroups are of bounded exponent, as in algebraic groups over fields of characteristic 2). In that context a body of results relating to fusion of 2-elements and the structure of 2-local subgroups is (...) needed: pushing up, and the classification of groups with strongly or weakly embedded subgroups, or have strongly closed abelian subgroups (c.f, [2]). Two theorems of Alperin-Goldschmidt type are proved here. Both are needed in applications.The following is an exact analog of the Alperin-Goldschmidt Fusion Theorem for groups of finite Morley rank, in the case of 2-elements:Theorem 1.1.Let G be a group of finite Morley rank, and P a Sylow2-subgroup of G.If A, B⊆P are conjugate in G, then there are subgroups Hi≤Pand elementsxi∈N(Hi)for1 ≤i≤n,and an elementy∈N(P),such that for all i:1.Hiis a tame intersection of two Sylow2-subgroups;2.CP(Hi) ≤Hi;3.N(Hi)/Hiis2-isolatedand(a)(b).

This study provides evidence regarding the level of ethical cognition of business students at the entry to college as compared to a national norm. It also provides comparative evidence on the effects of group versus individual ethical cognition upon completion of a business ethics course. The Principled Score (P-score) from the Defining Issues Test (DIT) was used to measure the ethical cognition of a total sample of 301 business students (273 entering students plus 28 students in a business ethics (...) course). The results indicate that (1) business students are not significantly different from the national norms at entry to college and (2) group reasoning helps male students improve their P-scores significantly in the business ethics course at a loss of P-score (albeit not statistically significant) for female students.

Eight focus groups were conducted in four public hospitals in Madrid to explore healthcare professionals’ perceptions of advance directives in order to improve the understanding of their lack of success among physicians and patients. A purposive sample of sixty healthcare professionals discussed ADs and reasons for their infrequent use. Three main themes were identified: perceptions about their meaning, appraisals of their use in clinical practice, and decision-making about them. Healthcare professionals perceived a lack of clarity about their definition and implementation. (...) There is insufficient awareness of their efficacy in improving the quality of clinical relationships and decision-making, and they are often perceived only as a bureaucratic procedure. Advance directives are not integrated in the clinical practice of Madrid’s healthcare specialist services because their application is exceedingly complex, because of insufficient education about them, and because of lack of procedural clarity. Consequently, healthcare professionals are not aware of how ADs could improve clinical decision-making, of when and for whom their use is appropriate, and of who has responsibility for providing ADs-related information to patients. These circumstances contribute to patients’ lack of interest in completing these documents and to physicians’ sceptical views about their usefulness. (shrink)

After the global economic collapse triggered by the Great Recession, there has been an increased interest in the potential psychological implications of periods of economic decline. Recent evidence suggests that negative personal experiences linked to the economic crisis may lead to diminished generalized trust (i.e., the belief that most of the people of the society are honest and can be trusted). Adding to the growing literature on the psychological consequences of the economic crisis, we propose that the perceived personal impact (...) of the economic crisis not only would undermine generalized trust but also may lead to increased interpersonal trust (i.e., directed to specific and close people) and depersonalized in-group trust (i.e., directed to individuals who, while strangers, belong to the same group [e.g., social class]). Across three studies (N = 1379), we tested these central hypotheses and ascertained whether the perceived personal impact of the crisis would predict these types of trust (assessed using questionnaire and behavioral measures) independent of individuals’ socioeconomic status. Non-experimental data from Study 1 revealed that a higher perceived personal impact of the crisis is related to lower levels of generalized trust and higher levels of interpersonal trust. These effects were independent of participants’ socioeconomic status. Non-experimental data from Study 2 replicated the findings obtained in Study 1 and also showed a positive association between the perceived personal impact of the crisis and depersonalized in-group trust. This pattern of results emerged even after controlling for socioeconomic status, gender, age, political orientation, religiosity, and unemployment status. In Study 3, using an experimental design, we found that the salience of a possible economic downturn led to decreased generalized trust and increased interpersonal and depersonalized in-group trust—independently of socioeconomic status—compared with the control condition. These results challenge the conventional wisdom that economic crises invariably undermine trust in others. The implications of the present research as well as future research directions are discussed. (shrink)

Misunderstandings often develop when scientists from different backgrounds use the same words (e.g., “selection”) when they mean different things by them. Theorists must therefore choose and define their terms carefully. In addition, proponents of “new” theories need to demonstrate empirically that theirs are more powerful than the existing theories they wish to supplant. Wilson & Sober have not yet done this.

Randomized controlled trials in educational research tend to be small. Small trials can have large, chance, imbalances in important covariates. For studies with sample sizes greater than 50, chance imbalances can be corrected using analysis of covariance; for small trials, however, statistical power is maximized if the trial is balanced and analysis of covariance is used in the analysis. The aim of the present study was to discuss methods of improving covariate balance in trial design and to demonstrate the method (...) of minimization. Using an exemplar of a cluster or class‐randomized trial with 29 classes, we employed minimization to achieve covariate balance. Minimization achieved good balance on four prognostic variables. Many trialists in education use restricted forms of allocation, including pairing or stratified randomization. These approaches have disadvantages. Another approach rarely used in educational research is minimization. Minimization uses a simple arithmetic algorithm to produce balanced groups across a number of important covariates and should be more widely used in educational and psychological research. (shrink)

In recent decades, the analysis of phraseology has made use of the exploration of large corpora as a source of quantitative information about language. This paper intends to present the main lines of work in progress based on this empirical approach to linguistic analysis. In particular, we focus our attention on some problems relating to the morpho-syntactic annotation of corpora. The CORIS/CODIS corpus of contemporary written Italian, developed at CILTA – University of Bologna (Rossini Favretti 2000; Rossini Favretti, Tamburini, De (...) Santis in press), is a synchronic 100-million-word corpus and is being lemmatised and annotated with part-of-speech (POS) tags, in order to increase the quantity of information and improve data retrieval procedures (Tamburini 2000). The aim of POS tagging is to assign each lexical unit to the appropriate word class. Usually the set of tags is pre-established by the linguist, who uses his/her competence to identify the different word classes. The very first experiments we made revealed how the traditional part-of-speech distinctions in Italian (generally based on morphological and semantic criteria) are often inadequate to represent the syntactic features of words in context. It is worth noting that the uncertainties in categorisation contained in Italian grammars and dictionaries reflect a growing difficulty as they move from fundamental linguistic classes, such as nouns and verbs, to more complex classes, such as adverbs, pronouns, prepositions and conjunctions. This latter class, that groups together elements traditionally used to express connections between sentences, appears inadequate when describing cohesive relations in Italian. This phenomenon actually seems to involve other elements traditionally assigned to different classes, such as adverbs, pronouns and interjections. Recent studies proposed the class of ‘connectives’, grouping all words that, apart from their traditional word class, have the function of connecting phrases and contributing to textual cohesion. From this point of view, conjunctions can be considered as part of phrasal connectives, that can in turn be included in the wider category of textual connectives. The aim of this study is to identify elements that can be included in the class of phrasal connectives, using quantitative methods. According to Shannon and Weaver’s (1949) observation that words are linked by dependent probabilities, corroborated by Halliday’s (1991) argument that the grammatical “system” (in Firth’s sense of the term) is essentially probabilistic, quantitative data are introduced in order to provide evidence of relative frequencies. Section 2 presents a description of word-class categorisation from the point of view of grammars and dictionaries arguing that the traditional category of conjunctions is inadequate for capturing the notion of phrasal connective. Section 3 examines the notion of ‘connective’ and suggests a truth-function interpretation of connective behaviour. Section 4 describes the quantitative methods proposed for analysing the distributional properties of lexical units, and section 5 comments on the results obtained by applying such methods drawing some provisional conclusions.

I advocate the use of small group learning in the philosophy classroom because it engages a broad cross-section of students and because it proves to be an effective way to teach critical thinking. In this article, I suggest small group activities that are useful for developing philosophical skills, and I propose methods for circumventing common logistical problems that can arise when implementing small group learning in the classroom. Ultimately, I show that small group learning is a (...) pedagogically powerful and logistically feasible supplement to traditional teaching methods. (shrink)

Regardless of formalization used, one on-going challenge for AI systems that model legal proceedings is accounting for contextual issues, particularly where judicial decisions are made in criminal cases. The law assumes a rational approach to rule application in deciding a defendant’s guilt; however, judges and juries can behave irrationally. What should a model prize: efficiency, accuracy, or fairness? Exactly whether and how to incorporate the psychology of courtroom interactions into formal models or expert systems has only just begun to be (...) examined in a serious fashion. Here, I outline data from the United States which suggest that trying to incorporate psychological biases into formal models of legal decision-making will be challenging. I focus on the use of neuroscience data in criminal trials, homing in on so-called group-to-individual inferences. I argue that data which should be the most effective at swaying judicial decisions are in fact those most likely not to make a difference in the disposition of the case. I conclude that judges often assign culpability by ignoring what our best science regarding how human decision-making occurs. (shrink)

Past research has found that mere in‐group/out‐group categorizations are sufficient to elicit biases in face memory. The current research yields novel evidence that mere social categorization is also sufficient to modulate processes underlying face perception, even for faces for which we have strong perceptual expertise: same‐race (SR) faces. Using the composite face paradigm, we find that SR faces categorized as in‐group members (i.e., fellow university students) are processed more holistically than are SR faces categorized as out‐group (...) members (i.e., students at another university). Hence, holding perceptual expertise with faces constant, categorizing an SR target as an out‐group member debilitates the strong holistic processing typically observed for SR faces. (shrink)

Women’s underrepresentation in science, technology, engineering, and mathematics (STEM) is related to the hierarchical social structure of gender relations in these fields. However, interventions to increase women’s participation have focused primarily on women’s interests rather than on STEM managers’ hiring practices. In this research, we examine STEM hiring practices, explore the implicit bias in criteria used by STEM managers, and suggest possible corrective solutions. Using an experimental design with 213 men and women STEM managers, we show that when evaluating a (...) female candidate, women and men STEM managers apply differential selection criteria, with men demonstrating implicit in-group gender favoritism in their hiring decisions. Specifically, the ability to work long hours was a more important criterion for male managers when evaluating a female candidate, forming an implicit gender bias, whereas female managers gave greater importance to problem-solving ability, a more gender-equal criterion. Adding a personal note to the curriculum vitae stating that the candidate had hired a full-time nanny was useful in decreasing the importance of the ability to work long hours criterion for men managers. We suggest individual and institutional interventions to reduce this bias, as a path to increasing women’s participation in STEM. (shrink)
