Two studies using novel extensions of the conditioned head-turning method examined contributions of rhythmic and distributional properties of syllable strings to 8-month-old infants' speech segmentation. The two techniques introduced exploit fundamental, but complementary, properties of representational units. The first involved assessment of discriminative response maintenance when simple training stimuli were embedded in more complex speech contexts; the second involved measurement of infants' latencies in detecting extraneous signals superimposed on speech stimuli. A complex pattern of results is predicted if infants succeed in grouping syllables into higher-order units. Across the two studies, the predicted pattern of results emerged, indicating that rhythmic properties of speech play an important role in guiding infants toward potential linguistically relevant units and simultaneously demonstrating that the techniques proposed here provide valid, converging measures of infants' auditory representational units.  相似文献

The current paradigm in medicine generally distinguishes between genetic and environmental causes of disease. Although the word paradigm has become a commonplace, the theories of Thomas Kuhn have not received much attention in the journals of medicine. Kuhn's structuralist method differs radically from the daily activities of the scientific method itself. Using linguistic theory, this essay offers a structuralist reading of Thomas Kuhn's The Structure of Scientific Revolutions. Our purpose is to highlight the similarities between these structuralist models of science and language. In part, we focus on the logic that enables Kuhn to assert the priority of perception over interpretation in the history of science. To illustrate some of these issues, we refer to the distinction between environmental and genetic causes of disease. While the activity of scientific research results in the revision of concepts in science, the production of significant differences that shape our knowledge is in part a social and linguistic process.  相似文献

Current models of face representation involve the notion of a high-dimensional face space. Computational models of face space based on principal components analysis (PCA) have been successfully used to predict human judgements of face sex or race. In this work the capability of PCA-based face spaces to predict human judgements of face similarity is examined. Three different paradigms were used. In Experiment 1 subjects learned face-name associations for 18 faces and identified these faces on tachistoscopic presentation. The number of confusions was used as a measure of face similarity. In Experiment 2 the same subjects subjectively rated the similarity of all 153 possible face pairs. In Experiment 3 reaction time to identify a face in an odd-man-out task was measured as an index of face similarity. These empirical measures were correlated with distance of the faces in PCA-based spaces of different dimensionalities. For Experiments 1 and 2 these correlations were highest for one-or two-dimensional face spaces (r=−0.27 vs. −0.28). For Experiment 3 the correlation was highest for a space consisting of 13 dimensions (r=−0.51). Thus PCA-based spaces seem capable to predict human similarity judgements to some extent. Possible reasons for the differences in predictability between paradigms are discussed.  相似文献

It has recently become popular to suggest that cognition can be explained as a process of Bayesian prediction error minimization. Some advocates of this view propose that attention should be understood as the optimization of expected precisions in the prediction-error signal (Clark, 2013, 2016; Feldman & Friston, 2010; Hohwy, 2012, 2013). This proposal successfully accounts for several attention-related phenomena. We claim that it cannot account for all of them, since there are certain forms of voluntary attention that it cannot accommodate. We therefore suggest that, although the theory of Bayesian prediction error minimization introduces some powerful tools for the explanation of mental phenomena, its advocates have been wrong to claim that Bayesian prediction error minimization is ‘all the brain ever does’.  相似文献

Having higher levels of mainstream cultural orientation (MCO), an important component of acculturation attitudes and behaviors, is beneficial for ethnic/racial minority students during the transitions into university. Scant research has investigated MCO at a micro daily timescale. This study examined how personality (agreeableness) functions in conjunction with interpersonal processes (inter-ethnic contact and perceived discrimination) to influence MCO as daily within-person processes.  相似文献

Retaining pregnant women and mothers is a prevalent challenge for companies in the United States. In this paper, we highlight the importance of favorable maternity benefits. Specifically, we argue that maternity benefits can signal how pregnant workers are treated within the organization, particularly as women compare their own benefits to referent others'. Drawing from identity threat response theory, we propose a conceptual framework that explains the influence of maternity benefit comparisons on perceptions of discrimination and, subsequently, turnover. Upon evaluating two studies using multi-wave survey data and two vignette studies, our results indicate that when women perceive their maternity benefits to be less favorable than referent others' benefits, they perceive more pregnancy discrimination. In turn, perceptions of pregnancy discrimination influence their subsequent turnover decisions. Consistent with identity threat response theory, our results also suggest that perceived supervisor support is a significant moderator, weakening the impact of maternity benefit comparisons on perceptions of pregnancy discrimination.  相似文献

Personal values have been widely recognized as important determinants of individuals’ behaviour. But can behaviour be shaped by the values one attributes to others? Focusing on interdependent interactions, this research integrates literature on personal values and the role of expectations in social dilemmas to investigate the overlooked effect of value perceptions on people's choices. In Study 1, players in a prisoner's dilemma (a game capturing cooperation vs. competition) who were informed that their partner prioritized self-transcendence values tended to cooperate more than players informed that the partner prioritized self-enhancement values. In Study 2, players in the same game who assumed their partner was higher in self-transcendence values and lower in self-enhancement values were more likely to opt for the cooperative choice. In Study 3, players in a chicken game (a game capturing risk-taking vs. risk-avoidance) who assumed their partner was higher in conservation values and lower in openness-to-change values were more likely to opt for the riskier choice in the game. Study 4 indicated that the effect of perceived values on behaviour is mediated by assumptions regarding the partner's choice. Perceived values of the other side predicted behaviour beyond the perceiver's own values. We discuss the relationships between own and perceived values and our contributions to the values literature and conflict research.  相似文献

Abstract

This paper addresses the important issues of making it as an Asian psychologist in an overwhelmingly white academic field. Based on my professional and personal struggle to achieve success as a psychologist in both academia and clinical practice, I want to (a) expose the naked truth of being an Asian psychologist within a white academic field with regard to racial trauma, careerism, and expediency; (b) chart a course of maintaining personal and ethnic authenticity in truth-seeking in spite of all the visible and invisible obstacles in a foreign country; and (c) propose ways to fully recognize indigenous psychology and integrate Asian minorities in mainstream psychology.  相似文献

ABSTRACT

Few studies investigated the effects of facial characteristics on stereotyping in the business context. Using a 2 (beard/no beard) x 2 (acne/no acne) x 2 (tie/no tie) x 2 (eyeglasses/no eyeglasses) between subjects’ design, two representative samples of 364 and 711 participants rated different stimuli of male subjects on dimensions of competence, warmth and hireability. Based on 4,215 observations, results show acne has a negative and eyeglasses a positive effect on both competence and warmth. Wearing a necktie has a positive effect on competence and a negative effect on warmth. Finally, beardedness has a negative effect on warmth. We also observe that competence has a greater effect on hireability than warmth. We discuss the findings in the context of theoretical and managerial implications for male job applicants as well as HR practices.  相似文献
