Houston‐Price and Nakai raise an important problem researchers face when attempting to interpret infant visual preference data. This problem stems from paradigms in which infants are only partially familiarized to a stimulus, and it is unclear whether they should show a novelty or familiarity preference to that stimulus in a subsequent test. As Hunter and Ames' (1988) noted in their important chapter, infants will sometimes show a familiarity preference rather than a novelty preference, particularly when the infants are relatively young and the stimuli are relatively complex. In this commentary, I shall make three points regarding this issue: first, that the familiarity preference problem is real; second, that in most cases there is a simple solution to the problem; and third that certain popular infant paradigms can exacerbate the problem.

Drawing on social identity theory, we examine how Whites’ race-related beliefs drive their reactions to race-based Affirmative Action Policies (AAPs). Across laboratory and field settings, we find that Whites with relatively high modern racism (MR) or collective relative deprivation (CRD) beliefs perceive greater White disadvantage in organizations that have race-based AAPs, than in organizations that do not. Alternatively, race-based AAPs do not lead to perceptions of White disadvantage among Whites with relatively low MR and CRD beliefs. We also find that White disadvantage mediates the relationship between the combined effects of race-based AAPs, MR beliefs, and CRD beliefs and the perceived fairness of the organization’s selection and promotion policies. Our findings suggest that race-based AAPs do not necessarily lead to perceptions of White disadvantage, but are contingent upon the interpretive lens of Whites’ MR and CRD beliefs, and also offer practical insights for preventing negative reactions to race-based AAPs. 相似文献

Although concrete nouns are generally agreed to have shared core conceptual representations across languages in bilinguals, it has been proposed that abstract nouns have separate representations or share fewer semantic components. Conceptual repetition priming methodology was used to evaluate whether translation equivalents of abstract nouns have shared conceptual representations and compare the degree of conceptual overlap for concrete and abstract nouns. Here 72 Spanish-English bilinguals made concrete-abstract decisions on English and Spanish nouns. Both concrete and abstract nouns elicited substantial between-language priming and these effects were of equivalent size, indicating that translation equivalents of both concrete and abstract nouns have shared conceptual representations and that abstract words do not share fewer components. The between-language priming effects and their attenuation relative to within-language priming indicate that the within-language effect is based on facilitation of both word comprehension and semantic decision processes. 相似文献

Hooking up generally involves casual sex with noncommittal partners. Hooking up is prevalent on college campuses today and can negatively affect the identity development of female students. The authors examined this phenomenon with a feminist developmental perspective, evaluating hooking up in the context of sexual risk taking with physical and psychosocial consequences. 相似文献

Mice can learn a food preference from odor cues transmitted on the breath of a conspecific, even if the “demonstrator” is anesthetized. To our knowledge there are no studies examining the effect of anesthetizing the “observer” on development of memory for socially transmitted food preferences (STFP). In Experiment 1 we found that 2–4 month-old F2 C57Bl/6x129sv male and female mice demonstrated a STFP after a 5 min exposure to an anesthetized demonstrator mouse when tested 24 h later. In Experiment 2, observer mice anesthetized with Sagatal (60 mg/kg) prior to the “social interaction” preferentially avoided the cued food when tested 24 h later. This aversion was not due to any overt aversive effects of this dose of Sagatal because mice that ate the food and were then anesthetized, or could only smell the food for 5 min while anesthetized, showed no preference or aversion. In a third experiment we found that the Sagatal-induced aversion was not a general property of anesthesia because there were varied results produced by observer mice treated with anesthetic drugs with different mechanisms of action. Vetalar (200 mg/kg) and Rompun (10 mg/kg) treated animals ate similar amounts of cued and non-cued food at test, indicating an absence of learning. Hypnorm (0.5 ml/kg) treated animals showed a preference for the cued food whereas those treated with Hypnovel (2.5 ml/kg) showed an aversion to the cued food. These results show that the food aversion observed with Sagatal is not a general property of anesthetic agents, but appears to be restricted to those acting primarily on the GABAergic system. Thus, we have shown that under certain conditions it is possible for an anesthetized observer mouse to learn a preference or aversion of a socially-linked olfactory cue. 相似文献

Is counter-terrorism policy evidence-based? What works, what harms, and what is unknown. One of the central concerns surrounding counter-terrorism interventions today, given the attention and money spent on them, is whether such interventions are effective. To explore this issue, we conducted a general review of terrorism literature as well as a Campbell systematic review on counter-terrorism strategies. In this article, we summarize some of our findings from these works. Overall, we found an almost complete absence of evaluation research on counter-terrorism strategies and conclude that counter-terrorism policy is not evidence-based. The findings of this review emphasise the need for government leaders, policy makers, researchers, and funding agencies to include and insist on evaluations of the effectiveness of these programs in their agendas. 相似文献

We form first impressions from faces despite warnings not to do so. Moreover, there is considerable agreement in our impressions, which carry significant social outcomes. Appearance matters because some facial qualities are so useful in guiding adaptive behavior that even a trace of those qualities can create an impression. Specifically, the qualities revealed by facial cues that characterize low fitness, babies, emotion, and identity are overgeneralized to people whose facial appearance resembles the unfit (anomalous face overgeneralization), babies (babyface overgeneralization), a particular emotion (emotion face overgeneralization), or a particular identity (familiar face overgeneralization). We review studies that support the overgeneralization hypotheses and recommend research that incorporates additional tenets of the ecological theory from which these hypotheses are derived: the contribution of dynamic and multi‐modal stimulus information to face perception; bidirectional relationships between behavior and face perception; perceptual learning mechanisms and social goals that sensitize perceivers to particular information in faces. 相似文献

Interview methods are widely regarded as the standard for the diagnosis of borderline personality disorder (BPD), whereas self-report methods are considered a time-efficient alternative. However, the relative validity of these methods has not been sufficiently tested. The current study used data from the Collaborative Longitudinal Personality disorder Study to compare diagnostic base rates and the relative validity of interview and self-report methods for assessing functional outcome in BPD. Although self-report yielded higher base rates of criteria endorsement, results did not support the common assumption that diagnostic interviews are more valid than self-reports, but instead indicated the combined use of these methods optimally identifies BPD criteria. 相似文献

We analyzed the effects of patterns of brain lesions from penetrating head injuries on memory performance in participants of the Vietnam Head Injury Study (Grafman et al., 1988). Classes of lesion patterns were determined by mixture modeling (L. K. Muthén & B. O. Muthén, 1998-2004). Memory performance was assessed for short-term memory (STM), semantic memory, verbal episodic memory, and visual episodic memory. The striking finding was that large STM deficits were observed in all classes of brain-injured individuals, regardless of lesion location pattern. These effects persist despite frequent concomitant effects of depressive symptomatology and substance dependence. Smaller deficits in semantic memory, verbal episodic memory, and visual episodic memory depended on lesion location, in a manner roughly consistent with the existing neuropsychological literature. The theoretical and clinical implications of the striking, seemingly permanent STM deficits in individuals with penetrating head injuries are discussed. 相似文献
