Competing theories of arousal versus salience and object enhancement vs. reduced perceptual processing as explanations for the weapon focus effect in eyewitness identification were examined. Male and female students ( N = 200) viewed a videotape of a male or female intruder rudely barging into a classroom while carrying a book, a gun, or an unusual object and demanding to know the whereabouts of another student. Feature accuracy recall of both the intruder and the object were assessed on a postexperimental questionnaire. Results supported the salience and reduced-perceptual-processing hypotheses, suggesting that weapon focus may be a special instance of a more general salient object effect. An own-gender bias in eyewitness identification was replicated when no weapon or unusual objects distracted eyewitnesses, but was reversed when a weapon or an unusual object was present. 相似文献

Inhibition of protein synthesis by anisomycin for a short duration impairs memory of a one-trial inhibitory avoidance task in rats. Memory of escape conditioning involving eight trials is disrupted only if the duration of protein synthesis is prolonged by repeated injections. In marked contrast, olfactory memory of rats trained on two odor discriminations is not affected by anisomycin even if the duration of inhibition is prolonged and the number of trials is reduced to a minimum. In previous work, leupeptin, a thiol proteinase inhibitor, was shown to impair olfactory discrimination learning, but left inhibitory and avoidance conditioning intact. Together, these results provide a pharmacological double dissociation of memory, and suggest that the same chemistries, or mixtures of chemistries, may not be involved in all types of memory. 相似文献

The Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A; Butcher et al., 1992) was released in 1992 and has rapidly become the most widely used objective personality assessment instrument with adolescents. Although the MMPI-A reduced or eliminated several problems associated with the use of the original MMPI (Hathaway & McKinley, 1943) with adolescents, the MMPI-A does produce a high frequency of within normal limits basic scale profiles for individuals with substantial psychopathology including adolescents in inpatient psychiatric settings. To better understand the reasons for this phenomenon, we compared the item endorsement frequencies for the MMPI-A normative sample with results from two adolescent clinical samples, and these results were contrasted to the item endorsement frequencies for the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) normative sample and a clinical sample of adult psychiatric inpatients. Results showed that the MMPI-A contains a substantial number of items that do not show a significant difference in item endorsement frequency between normative and clinical samples. Furthermore, MMPI-A basic and content scales generally show a much lower percentage of effective items than do the corresponding scales for the MMPI-2. We discuss the findings in relation to the frequent occurrence of low range MMPI-A profiles in clinical samples and the potential usefulness of these results in future efforts to develop viable short forms for the MMPI-A. 相似文献

A number of philosophers and feminist authors have recently equated domestic abuse with the ubiquitous and ill‐defined concept of “terrorism.” Claudia Card, for instance, argues that domestic abuse is a frequently ignored form of terrorism that creates and maintains “heterosexual male dominance and female dependence and service” (Card 2003). Alison Jaggar, in a recent article, also concludes that an acceptable definition of terrorism will find rape and domestic violence to be terrorist acts (Jaggar 2005). Yet there seem to be several obstacles to any simple appropriation of the term “terrorism” for cases of domestic abuse. In this paper I will address what I take to be three significant problems that might be raised with regard to any attempt to identify domestic abuse as an act of terrorism. These problems include the fact that a) definitions of terrorism usually require clear political motivations, b) definitions of terrorism normally require that the terrorist intend to create a climate of terror, and c) adopting the term terrorism for cases of domestic abuse might appear simply inappropriate or unhelpful. I will argue, however, that each of these possible objections can be answered effectively and that domestic abuse rightly falls under the rubric of terrorism. 相似文献

According to the classic symptom perception hypothesis (Costa & McCrae, 1987; Watson & Pennebaker, 1989), the global predisposition to frequently experience a variety of negative emotions-that is, neuroticism (N) or trait negative affectivity (NA)-is associated with inflated physical symptom reporting. We tested a revision of this hypothesis, which posits distinctive roles for depression and anxiety in the physical symptom experience. Three studies tested predictions from the revised symptom perception hypothesis: (a) that depressive affect should be related to inflated retrospective physical symptom reports and (b) that anxious affect should be related to inflated concurrent, or momentary, physical symptom reports. Study 1 assessed the relations among N/NA, depressive affect, and recall of physical symptoms experienced in the previous 3 weeks. Depressive affect was uniquely and positively associated with recalling more symptoms. When entered with depressive affect in multiple regression analyses, neuroticism was not associated with level of symptoms recalled. In Study 2, participants were randomly assigned to anxious, depressed, angry, happy, or neutral mood inductions and then reported about concurrent symptom experience. Participants in the anxious mood condition reported significantly more concurrent physical symptoms than did those in the other 4 conditions. In Study 3, anxious, depressed, or neutral mood was induced, followed by assessment of both concurrent and retrospective physical symptoms. Those assigned to the anxious mood induction reported more concurrent symptoms, while those in the depressed mood condition reported having experienced more symptoms in the past. These findings are consistent with the idea that encoding and retrieval processes, which are differentially associated with anxious versus depressed affect, influence different aspects of physical symptom reporting. The results have implications for self-diagnosis, medical treatment-seeking, and care, and potential insights about other complex social and interpersonal behaviors are discussed. 相似文献

Two studies tested the hypothesis that SWB predicts unique variance in academic citizenship attitudes, even while accounting for personality traits. In Study 1, participants (n?=?2,566) completed an online questionnaire assessing their positive and negative affect, ACBs and personality. The results indicated that positive affect predicted consideration, civic virtue, and conscientiousness, whereas negative affect predicted citizenship conscientiousness and sportsmanship while controlling for personality. In Study 2, participants (n?=?260) completed measures of life satisfaction, ACBs and personality. The results showed that life satisfaction predicted all ACBs while controlling for personality. Based on these results, it can be concluded that SWB is an important predictor of ACBs. Implications for the selection of student aids in academic settings are discussed. 相似文献
