The purpose of the present research was to investigate the relationship between passion for driving and aggressive driving behavior in 3 studies. Study 1 examined the association between passion and aggressive driving behavior in a sample of undergraduate students. Results showed that an obsessive passion for driving was associated with aggressive driving behavior, while harmonious passion was not. Study 2 replicated these results with an ecologically valid sample of community‐dwelling drivers. Finally, Study 3 replicated the results obtained in Studies 1 and 2 in a laboratory setting using a driving simulator under controlled frustrating driving situations with judges' assessment of aggressive driving behavior. Study 3 also showed that the emotion of anger mediated the obsessive‐passion/aggressive‐driving‐behavior relationship. 相似文献

This study tested the effect of semantically-induced thoughts of love on chivalrous helping. A field setting of four hundred
and one participants was divided into two groups. One group was interviewed and asked to retrieve the memory of a love episode,
and the second group, the control group, was asked to retrieve a piece of music that they love. The two groups encountered
another confederate, who inadvertently lost a stack of compact discs when they neared each other. The results demonstrated
that participants were more helpful when they were male, when the person in need of help was female, and when they were induced
to retrieve the memory of a love episode. 相似文献

Categorical flexibility in preschoolers: contributions of conceptual knowledge and executive control
The current study evaluated the relative roles of conceptual knowledge and executive control on the development of categorical flexibility, the ability to switch between simultaneously available but conflicting categorical representations of an object. Experiment 1 assessed conceptual knowledge and executive control together; Experiment 2 differentiated conceptual knowledge from costly executive processes. In Experiment 1, 3‐ to 5‐year‐olds were given a three‐choice (taxonomic, thematic, and nonassociate) match‐to‐sample task and asked to match two associates. In Experiment 2, same‐aged children were assessed on another match‐to‐sample task that reduced executive costs by presenting thematic and taxonomic associates on separate trials. By comparing performance across tasks, age‐related changes resulting from conceptual knowledge and executive control indicated that conceptual knowledge of superordinate relations showed gains between 3 and 4 years, whereas gains in executive control were seen between 4 and 5 years, suggesting a décalage in the development of conceptual and executive processes underlying categorical flexibility. 相似文献

The aim of this study was to measure the pattern of hand preferences for pointing gestures as a function of object‐manipulation handedness in 123 infants and toddlers (10–40 months). The results showed that not only right‐handers but also left‐handers and ambidextrous participants tended to use their right hand for pointing. There was a significant correlation between manual preferences and pointing lateralization. Further analyses showed that the correlation between these two indexes was at its strongest during two key phases of language development (i.e. vocabulary spurt and syntax improvement) and weakened to become nonsignificant in the interim. These findings support the view that humans have a specialized area for communicative gestures and language in the left cerebral hemisphere that may be independent of the system controlling the purely motor functions of hand use. 相似文献

The neurosteroid dehydroepiandrosterone (DHEA) is a powerful inhibitor of aggression in murine models when given for 15 days and potentially may be useful in the management of inappropriate human aggression. Although the biosynthesis and metabolism of DHEA have been described, little is known about the potential effect of the steroidal environment during sexual differentiation on the subsequent response to DHEA. Whether prenatal androgen exposure influences the subsequent response to DHEA was assessed by comparing the effect of DHEA (80 μg/d) on aggression in female offspring where dams were treated with 1, 10, or 100 μg of testosterone (T) on days 15 to 18 of gestation (Experiment I) or that developed in different uterine positions (Experiment II). The results showed that DHEA decreased attack behavior in general and that the 100‐μg prenatal T treatments enhanced the antiaggressive effect of this neurosteroid. Neither the lower doses of exogenously administered T nor the uterine position led to an enhanced response to DHEA. In addition, whether DHEA produced changes in social and nonsocial activities was examined. In the 100‐μg T females, DHEA increased the duration of the former and decreased the frequency and duration of the latter, indicating that it was not a general decrement in behavioral expression that mediated the enhanced response to the antiaggressive effect of DHEA. In the second experiment, DHEA treatment led to increased frequencies of social nonaggressive and nonsocial activities. However, the uterine positions × treatment interactions were not significant, demonstrating that contiguity to male fetuses did not differentially affect the response to DHEA. Aggr.

The present study reinforced the two instructors of two students with profound mental retardation first for the instructors' training behaviors, then for improved student learning in a multiple baseline across responses design. Reinforcement of the instructors' training behaviors increased their training behaviors, replicating the findings of previous studies, but had no effect on student learning. When the reinforcement for the instructors was instead made contingent upon student learning, the student learning improved and the instructors' high level of training behaviors was maintained. In addition, the instructors began to request training for themselves. These findings suggest that staff motivation programs for instructors might usefully base the reinforcers not only on the instructor's performance, but on the progress of their students. 相似文献
