Green's well-known area theorem establishes an equivalence between the area under the yes-no ROC curve and the percent correct of an unbiased observer in a two-alternative forced-choice (2AFC) task with equivalent stimuli. In this article, we show that this conversion from yes-no detection data to hypothetical performance in a 2AFC task is unnecessary: The same yes-no detection data that are used to compute the area statistic can always be used to compute the percent correct of an unbiased observer in the yes-no detection task itself. We also show that the ROC curve may not be the ideal graphical device for many investigators. A more natural representation of the difficulty of a discrimination task is obtained by plotting the distribution of the posterior betting odds under equal base rates, which can be estimated from their distributions under unequal base rates. Finally, unlike the area measure and other traditional detection theory statistics, both the yes-no percent correct measure and the odds distributions generalize in an obvious and direct way to classification paradigms with more than two responses (e.g., identification).  相似文献

The post–World War II era was one of great triumph for American linguists—and yet linguistics is all but absent from the historical literature on postwar social science. This paper aims to illuminate this curious situation: to understand its provenance, evaluate its merits, and contextualize it broadly. I argue that the historiographic lacuna results from two factors: (1) the opt‐out of linguists from the wider American social science community, and (2) historical‐developmental and ‐orientational factors that stand linguistics apart from the social science mainstream. The resultant isolation of linguistics has led to a parallel isolation in the historical literature. Ultimately, this paper poses a pivotal and timely question: How is the postwar social science space construed within the existing historiographic framework, and how should it be construed in order to maximize understanding? I propose a rethink of the received historiography centered on intellectual transformations and cross‐disciplinary integration. © 2011 Wiley Periodicals, Inc.  相似文献

The nature of the cognitive processes that give rise to moral judgment and behavior has been a central question of psychology for decades. In this paper, we suggest that an often ignored yet fruitful stream of research for informing current debates on the nature of moral cognition is social influence. We introduce what we call the “social‐moderation‐of‐process” perspective, a methodological framework for leveraging insights from social influence research to inform debates in moral psychology over the mechanisms underlying moral cognition and the moral domains in which those mechanisms operate. We demonstrate the utility of the social‐moderation‐of‐process perspective by providing a detailed example of how research on social influence in behavioral ethics can be utilized to test a research question related to a debate between two prominent theories in moral psychology. We then detail how researchers across the field of moral psychology can utilize our social‐moderation‐of‐process perspective.  相似文献

Two experiments dealing with the effects of a majority or a minority source influence, solely on the recognition of a portrait, let us study the generalization of the influence to a portrait symbolically linked to a colour. According to the theory of conversion, the bringing into play of the validation process of the stimulus when the source is a minority should allow such a generalization cognitive association. When the source is a majority, a social comparison process should lead to compliance about the portrait, without any cognitive investigation of the whole stimulus. In the first experiment, four slides were shown successively using material similar to Luchins' (1945) and progressively drawing the portrait of Lenin, with a red-orange background for each phase. The dependant variables are: (1) the drawing, (2) the colour of the background, (3) the after-image. On the two last slides for which the answer ‘Lenin’ is given by the source, changes towards red (and the complementary colour green), in the absence of the source under the minority influence, and changes towards orange under majority influence in the absence of the source are registered. Moreoever, the most significant changes of the colour judgment are due to the subjects who refuse to answer ‘Lenin’ during the interaction. In the second experiment, only the fourth slide, on which Lenin's portrait completely appears is shown. The subjects submitted to majority influence answer ‘Lenin’ more than the control group does, only in the presence of the source and change their judgment on the colour of the after-image towards the complementary of orange in the absence of the source. When the source is a minority a sinificant effect towards the red and its complementary colour is shown.  相似文献

Using the example of Fred Newman’s social therapy, a methodology that works with the human capability of growing as social units, the contemporary self is explored as an impediment to human development and learning. Following Karl Marx in political philosophy and Lev Vygotsky in child psychology, it is the group/the collective/the mass that engages in developmental activity. In losing the self, we gain the opportunity to create collectivity and in that process come to sense the social-relational-collective quality of creativity and development. By getting rid of the self, we are more able to see the group, which is—developmentally speaking—the important unit of study. In this article I share the role that Marx, Vygotsky and Ludwig Wittgenstein played in the creation of this understanding and critical practice.  相似文献

This exploratory investigation employs the National Education Longitudinal Surveybreak(NELS:88) to examine equity in tracking from a new, less-studied angle, with the view that tracking may not be all good or all bad, but that its effects are variable. The present study considers how these variable effects might, in part, be produced through a mechanism of social comparison conceptualized by Marsh et al. as the big-fish-little-pond effect (BFLPE). It compares similar students, except that some are in schools that use tracking and some are in schools that do not use tracking. Unlike previous studies of between-track effects, it asks whether tracking works uniformly for males and females within the same track placement in a particular subject area. Analyses yielded significant differences in students' attitudes toward mathematics, educational aspirations, self-esteem, locus of control, and engagement in school. These systematic effects suggest the mechanisms of the BFLPE. Despite the reflected glory of being in a high ability track, when males, in contrast to females, are grouped with peers of similar high ability in a subject area that defines their competence, they seem to lose their competitive edge. Low ability males are positively affected through the mechanism of comparing with their peers because the competition to do well is relatively less keen than in high tracks.  相似文献

The paper presents an outline of a unified answer to five questions concerning logic: (1) Is logic in the mind or in the world? (2) Does logic need a foundation? What is the main obstacle to a foundation for logic? Can it be overcome? (3) How does logic work? What does logical form represent? Are logical constants referential? (4) Is there a criterion of logicality? (5) What is the relation between logic and mathematics?  相似文献

This review article addresses the historical argument of Norenzayan's Big Gods. It questions the claim that there is enough historical evidence to support the thesis that gods, who are observing human behaviour from high, enable societies to grow beyond the stage of face-to-face groups.  相似文献

The period following UK's European Union referendum in 2016 foreshadows significant social and political change in the UK. The current research draws on social psychological theories to empirically examine the drivers of voting decisions during the referendum. We report the results of a prospective study using structural equation modelling with data (N = 244) collected just before, and self‐reported voting behaviour immediately following (N = 197), the European Union referendum. We employ a person and social approach to examine the additive roles of worldview, conservatism, social identity, and intergroup threat as predictors of voting intentions and behaviour. Results showed that person factors (worldview and conservatism) predicted voting intentions through social factors (European identity and realistic threat) and that intentions predicted behaviour. The results highlight the importance of addressing threat‐based intergroup rhetoric and the potential of common in‐group identity to mitigate psychological threat.  相似文献

I define humility as a virtue that includes both proper self‐assessment and a self‐lowering other‐centeredness. I then argue that humility, so understood, is a virtue in the context of sport, for several reasons. Humility is a component of sportspersonship, deters egoism in sport, fuels athletic aspiration and risk‐taking, fosters athletic forms of self‐knowledge, decreases the likelihood of an athlete seeking to strongly humiliate her opponents or be weakly humiliated by them, and can motivate an athlete to achieve greater levels of excellence in her sport. In the context of team sports, humility can contribute to an athlete being a better teammate, foster unity amidst diversity within a team, and contribute to the overall moral and athletic excellence of a team. I also argue that an individual who is truly the world's greatest athlete can know and communicate this truth, while remaining humble.  相似文献

Spouses often report that wives provide better social support than husbands. Yet studies observing spouses' supportive interactions challenge this perception, finding no differences between husbands' and wives' supportive behaviors. This article offers reconciliation by suggesting that husbands and wives may differ, not in their skill at providing support, but in their responsiveness to their partners' changing needs over time. Observational and diary data from couples confirmed that, whereas husbands and wives did not differ on average in the support they provided each other, they did differ in the timing of that support. Wives tended to provide better support on days that their husbands experienced greater stress. However, when wives experienced greater stress, their husbands displayed both support and negativity.  相似文献

Indian and American adults' and children's (N = 400) moral reasoning about hypothetical situations in which an agent failed to help someone experiencing either life-threatening, moderately serious, or minor need was compared. For 1/3 of Ss, the agent's relationship to the needy other was portrayed as that of parent; for another 1/3, as that of best friend; for the rest, as that of stranger. Indians tended to regard the failure to aid another in moral terms in all conditions. In contrast, Americans tended to view it in moral terms only in life-threatening cases or in cases of parents responding to the moderately serious needs of their children. The results imply that Indian culture forwards a broader and more stringent view of social responsibilities than does American culture. Discussion centers on theoretical implications of the various cultural, need, role, and developmental effects observed.  相似文献

The difficulties of deciding whether subjective time grows as a linear or nonlinear function of real time are discussed, and two experiments are presented to address this question. In Experiment 1, people received a 10-s standard duration and then had to judge what proportion other durations (ranging from 1 to 10 s) were of the standard. Counting was prevented by a concurrent task. The relation between judged and actual proportions was linear. In Experiment 2, people were required to average together three tone durations (mean duration 600 ms) and to judge whether subsequently presented comparisons were or were not the average. The spacing of the tone durations had no effect on judgements, suggesting a linear underlying time scale.  相似文献
