In two studies, we document “failure to warn”—a reduced likelihood of warning Black students against potential academic difficulty compared to White students. In both studies, participants placed in the role of academic advisors saw a highly challenging academic course plan, attributed to either a Black or a White student, and gave Black students less warning about the potential negative consequences of taking on the proposed plan. Study 1 (N = 172) demonstrates this effect using undergraduate peer academic advisors, and Study 2 (N = 58) provides evidence that this effect is moderated by Internal Motivation to Respond Without Prejudice (Plant & Devine, 1998), suggesting that this effect is driven by the fear that discouraging an ambitious Black student might reflect prejudice. This well-intentioned concern can have the ironic consequence of leading the recipients of this advice into academic difficulties.  相似文献

In this paper we consider the emerging position in metaphysics that artifact functions characterize real kinds of artifacts. We analyze how it can circumvent an objection by David Wiggins (Sameness and substance renewed, 2001, 87) and then argue that this position, in comparison to expert judgments, amounts to an interesting fine-grained metaphysics: taking artifact functions as (part of the) essences of artifacts leads to distinctions between principles of activity of artifacts that experts in technology have not yet made. We show, moreover, that our argument holds not only in the artifactual realm but also in biology: taking biological functions as (part of the) essences of organs leads to distinctions between principles of activity of organs that biological experts have not yet made. We run our argument on the basis of analyses of artifact and biological functions as developed in philosophy of technology and of biology, thus importing results obtained outside of metaphysics into the debate on ontological realism. In return, our argument shows that a position in metaphysics provides experts reason for trying to detect differences between principles of activities of artifacts and organs that have not been detected so far.  相似文献

We propose a model documenting the relationship between interpersonal attachment style and identification with groups. We hypothesized that following threat to a romantic interpersonal relationship higher attachment anxiety would be associated with lowered tendencies to identify with groups. In two studies using varied social groups we observed support for this hypothesis. In Experiment 1 we found that participants higher in attachment anxiety identified less with a salient ingroup after imagining a distressing argument with their romantic partner. In Experiment 2 we replicated these findings using an implicit measure of social identification and additionally observed a moderating role for attachment avoidance. We discuss the implications of these findings for theoretical models of interpersonal attachment and social identification.  相似文献

We present a study of the sociopsychological profiles of students who are disposed to engage in social competition on behalf of ingroup interests. Five predictors were selected: the advantageous or unfavourable context for ingroup interests, group identification, meritocracy, just-world beliefs, and social dominance orientation. It was found that those students who were prepared to invest personal resources on behalf of ingroup interests were characterized by a strong group identification and middle or low scores in the meritocracy and social dominance orientation. In contrast, students with the lowest disposition to social competition were defined by their low identification and/or middle-high scores in the meritocracy and social dominance orientation. Against our expectation, the manipulation of the favourable versus unfavourable situation of the ingroup did not have a significant influence. In order of their importance, the variables that showed stronger effects were group identification, followed by meritocracy, social dominance orientation, and world-just beliefs.  相似文献

A case study is presented of a client, involved in business dealings and personal relationships with members of organized crime, who upon looking into his mirror one morning recognized for the first time that his life was quickly slipping away. Unless he broke free, he decided, by doing something bold and outrageous—in the style of his free-spirited and violent youth—he was doomed to a depressive existence for the remainder of his days. He stalked women by night. Disturbed by a series of frightening dreams of his involvement in the murder of a stalked and raped woman, he approached the author for psychological help. During the course of treatment it became apparent that the client lacked a sense of personal goodness. An exploration of the problematic nature of virtue and constructive behavior in psychotherapeutic theory is presented here, together with a rationale for the role of the therapist as mentor as well as therapist for people who lack early and present experiences with constructive role models.  相似文献

We propose a method for detecting influential observations in iterative principal factor analysis. For this purpose we derive the influence functionsI(x; LL T ) andI(x; ) for the common variance matrixT =LL T and the unique variance matrix , respectively, in the common factor decomposition =LL T + . A numerical example is given for illustration.The authors are grateful to Tomoyuki Tarumi and Atsuhiro Hayashi for their kind permission to use their software Seto/B for drawing Figures 1 and 2 and to anonymous reviewers for comments on the paper.  相似文献

Abstract. The traditional Chinese idea of t'ien-jen-ho-i (Heaven and humanity in union) implies that humanity has to live in harmony with nature. As science and technology progress, however, the idea appears increasingly outmoded, and it becomes fashionable to talk about overcoming nature. Ironically, though, the further science reaches the more clearly are its limitations exposed. The exploitation of nature not only endangers many life forms on earth but threatens the very existence of the human species. I propose that a reconstruction of the traditional Chinese idea of T'ien-jen-ho-i will help us envisage a new and salutary relation between humanity and nature.  相似文献

Monocular depth perception was compared with binocular depth perception in 5- and 7-month-old infants. Reaching was used as the dependent measure. Two objects, identical except in size, were presented simultaneously to each infant. The smaller object was within reach for the infants while the larger object was just beyond reach. The two objects subtended equal visual angles from the infants' observation point. With binocular presentation, 96% of the 7-month-olds' reaches and 89% of the 5-month-olds' reaches were for the nearer object. With monocular presentation, 58% of the 7-month-olds' reaches and 65% of the 5-month-olds' reaches were for the nearer object. The reaching preferences observed in the monocular condition indicated sensitivity to monocular depth information (motion parallax, accommodation, and relative size information were available). Binocular viewing, however, resulted in a far more consistent tendency to reach for the nearer object. This result suggests that the infants' perception of the objects' distances was more veridical in the binocular condition than in the monocular condition.  相似文献
