The effect of sex, status, and mating cues on expected aggression was examined via three scenario‐based studies in which participants imagined themselves in a situation with a same‐sex instigator of a provocation. Participants were randomly assigned to receive a scenario, which included one of two levels of status of instigator (high, low), one of two levels of attractiveness of the instigator (unattractive, attractive), and one of two levels of provocation (apology, insult). Sex and dispositional aggressivity were also included in a full factorial design. Based on evolutionary psychology ideas, we anticipated that status and attractiveness would differentially influence expected aggression for men vs. women. Participants in Experiment 1 were instructed to imagine that they were alone, whereas participants in Experiments 2 and 3 imagined themselves in a situation that included mating‐related primes. In general expected aggression was greater for aggression‐prone participants and under conditions of provocation and/or a high‐status instigator. Experiments 2 and 3 found that, in the context of mate competition, sex differences in the effects of instigator provocation, status, and attractiveness emerged: greater aggressivity now only predicted more aggression for males but not females who were insulted; aggression was highest for females confronting an unattractive, high‐status instigator and for males confronting an attractive, high‐status instigator; females were more likely to aggress against a high‐status instigator, regardless of being in a steady relationship or a first date situation, but males were only more likely to aggress against a high‐status instigator in a first date situation.

Although current research indicates that psychotherapeutic change both affects and is affected by spiritual concerns, relatively little is known about the degree to which spirituality is used as an intervention in counseling and how it is perceived by clients and mental health professionals. The purpose of this study was to examine the perceptions of clients and professionals regarding the use of spirituality in counseling. The results suggest that more professionals may be using spirituality in counseling than has previously been reported. 相似文献

Performance on complex decision-making tasks may depend on a multitude of processes. Two such tasks, the Iowa Gambling Task (IGT) and Balloon Analog Risk Task (BART), are of particular interest because they are associated with real world risky behavior, including illegal drug use. We used cognitive models to disentangle underlying processes in both tasks. Whereas behavioral measures from the IGT and BART were uncorrelated, cognitive models revealed two reliable cross-task associations. Results suggest that the tasks similarly measure loss aversion and decision-consistency processes, but not necessarily the same learning process. Additionally, substance-using individuals (and especially stimulant users) performed worse on the IGT than healthy controls did, and this pattern could be explained by reduced decision consistency. 相似文献

This article extends an imputed pitch velocity model of the auditory kappa effect proposed by Henry and McAuley (2009a) to the auditory tau effect. Two experiments were conducted using an AXB design in which listeners judged the relative pitch of a middle target tone (X) in ascending and descending three-tone sequences. In Experiment 1, sequences were isochronous, establishing constant fast, medium, and slow velocity conditions. No systematic distortions in perceived target pitch were observed, and thresholds were similar across velocity conditions. Experiment 2 introduced to-be-ignored variations in target timing. Variations in target timing that deviated from constant velocity conditions introduced systematic distortions in perceived target pitch, indicative of a robust auditory tau effect. Consistent with an auditory motion hypothesis, the magnitude of the tau effect was larger at faster velocities. In addition, the tau effect was generally stronger for descending sequences than for ascending sequences. Combined with previous work on the auditory kappa effect, the imputed velocity model and associated auditory motion hypothesis provide a unified quantitative account of both auditory tau and kappa effects. In broader terms, these findings add support to the view that pitch and time relations in auditory patterns are fundamentally interdependent. 相似文献

Guns figure prominently in American culture. There is, however, considerable variability in attitudes toward guns. The beliefs and feelings that comprise attitudes toward guns may well be important moderators of numerous social behaviors. For this reason, a three-dimensional attitudes scale was constructed. The first factor consists of an abstract set of beliefs concerning the right of the American public to own or not own guns. The second and third factors tap more concrete beliefs about the consequences of gun ownership. Specifically, the second factor assesses the degree to which people believe gun ownership affords protection against crime. The third factor measures the degree to which people believe guns stimulate crime. Discriminant validity of the subscales is shown by the pattern of correlations obtained with the three dimensions and various other social and personality measures. Regression analyses indicate that the subscales are uniquely predicted by different social variables. Discussion centers on the usefulness of such a measure for future research on aggression, social policy, and attitude change. 相似文献

The differentiation of subtypes of primary progressive aphasia (PPA) remains challenging. We aimed to identify optimum neuropsychological measures for characterizing PPA, to examine the relationship between behavioural change and subtypes of PPA and to determine whether characteristic profiles of language, working memory, and behavioural changes occur in PPA. Forty-seven patients with PPA and multi-domain Alzheimer's disease (AD) together with 19 age-matched controls underwent a large battery of working memory and language tests. We found that simple tasks of sentence ordering, narrative production, and buccofacial praxis were particularly useful in differentiating non-fluent/agrammatic variant PPA (nfvPPA) from other PPA subtypes, whereas a test of single word comprehension was useful in detecting semantic dementia (SD). No individual tests were discriminating for logopenic variant PPA (lvPPA) relative to nfvPPA. LvPPA and multidomain AD exhibited similar language profiles. A principal components analysis revealed that characteristic PPA profiles extended beyond the realms of language, in particular, the presence of apraxia in nfvPPA, behavioural changes in SD, and working memory deficits in lvPPA. These findings suggest that not all tests are equally discriminatory for PPA and highlight the importance of a test profile in differentiating PPA. These results also support the view that lvPPA is a focal form of AD and emphasize the difficulties classifying lvPPA. 相似文献
