The aim of the present study is to elucidate the influence of context on the kinematics of the reach-to-grasp movement. In particular, we consider two basic modes of social cognition, namely cooperation and competition. In two experiments kinematics of the very same action - reaching-to-grasp a wooden block - were analyzed in two different contexts provided by a cooperative task and competitive task. For the 'cooperation' tasks two participants were required to reach and grasp their respective objects and to cooperate to join the two objects in specific configurations in the middle of the working surface. For the 'competition' tasks, the two participants had to compete to place their own object first in the middle of the working surface. Results revealed specific kinematic patterns for cooperation and competition which were distinct from similar actions performed by each participant in isolation. Further, during the cooperation tasks, a high level of correlation between key kinematical parameters of the two participants was found. In accordance with evidence from neuroimaging, developmental and social psychology our results suggest the existence of motor patterns which reflect the intention to act in a social context. 相似文献

Two experiments contrasted interactions between group leaders with interactions between individuals in a mixed-motive setting. Consistent with the idea that being accountable to the in-group implies normative pressure to benefit the in-group, Experiment 1 found that accountable leaders were more competitive than individuals. Consistent with the idea that being unaccountable to the in-group implies normative pressure to be cooperative and that high guilt proneness provides motivation to be moral, Experiment 2 found that when guilt proneness was high, unaccountable leaders were less competitive than accountable leaders and did not differ significantly from individuals. In other words, the robust interindividual-intergroup discontinuity effect was eliminated when groups had unaccountable leaders who were high in guilt proneness. 相似文献

To assess the diagnostic accuracy of the Personality Assessment Inventory (PAI; Morey, 1991) Validity scales for the detection of malingered psychiatric disorders, we divided a sample of criminal defendants referred for forensic evaluation by the federal courts into malingering and not malingering groups based on their performance on the Structured Interview of Reported Symptoms (Rogers, Gillis, & Bagby, 1990). Logistic regression analyses (LGAs) revealed that there were no differences between the malingering and not malingering groups with respect to age, race, years of education, history of drug abuse, or number of previous felony convictions. LGA with malingering versus not malingering as the criterion revealed that the PAI Negative Impression Management (NIM) scale but not the Rogers Discriminant Function (RDF; Rogers, Sewell, Morey & Ustad, 1996) nor the Malingering index (MAL; Morey, 1996) significantly differentiated the malingering from the not malingering group. Receiver operating characteristics analyses demonstrated acceptable sensitivity and specificity for the NIM scale but not the RDF scale or the MAL index. We discuss the results in terms of the suggested cutoff scores for the PAI Validity scales in detecting criminal defendants who are attempting to feign psychiatric disorder. 相似文献

The Varieties of Forgiveness Experience: Working toward a Comprehensive Definition of Forgiveness 总被引:1,自引:0,他引:1

The definition of forgiveness was explored in a group of 270 young adults, and the underlying dimensions of their definitions
compared with those of philosophers, theologians and psychological researchers. Three dimensions were identified: orientation
(self, other), direction (passive letting go of negative experiences, active enhancement of positive experiences) and form
(emotion, cognition and behavior). Definitions employing a passive letting go of negative experiences were associated with
more state forgiveness. Gender differences were found in state forgiveness and in the employment of passive vs. active dimensions
of forgiveness.
Dr. Kathleen A. Lawler-Row is Professor of Psychology at East Carolina University. Her work focuses on the physiological and
health correlates of forgiveness. Correspondence to Dr. K. A. Lawler-Row, e-mail: rowk@ecu.edu.

Research employing the Iowa Gambling Task (IGT) has frequently shown that learning is impaired in various clinical populations. However, precisely what constitutes "unimpaired" control group learning remains unclear. In order to understand some of the possible factors underlying variability in control group IGT performance, the present study sought to manipulate features of the task to intentionally disrupt learning. Specifically, the present study investigated the effects of time constraints on emotion-based learning during automated administration of the IGT. For two groups of participants, a time-constraint of either 2-s or 4-s was implemented during the critical decision making period, while a control group received no time constraint. We also evaluated participants' subjective experience after every block of 20 trials. Results demonstrated that the 2-s group differed significantly from the control group. Subjective experience measures revealed rapid development of awareness of the advantageous and disadvantageous decks among all three groups. Overall, our findings demonstrate, for the first time, the effects of decision-phase time constraints on emotion-based learning and indicate that the IGT reward/punishment schedules are to some extent cognitively penetrable. 相似文献

Joint effect of dopaminergic genes on likelihood of smoking following treatment with bupropion SR. 总被引:1,自引:0,他引:1

OBJECTIVE: To determine the relationship between joint variation in 2 dopaminergic genes and the likelihood of nonsmoking following treatment with bupropion sustained release (SR). DESIGN: Three hundred twenty-three participants in a bupropion SR smoking cessation effectiveness trial with 12-month follow-up were genotyped for variants of dopamine receptor gene DRD2 and dopamine transporter SLC6A3. MAIN OUTCOME MEASURES: Self-reported 7-day point prevalence of nonsmoking. RESULTS: Neither genotype alone was associated with 7-day point-prevalent nonsmoking at the 12-month follow-up. However, in the presence of the DRD2 A1 allele, SLC6A3 status was significantly associated with the likelihood of nonsmoking at the 12-month follow-up (individuals with DRD2 A1+ and SLC6A3 9- were more likely to be smoking). In the absence of the DRD2 A1 allele, the association between SLC6A3 status and nonsmoking was nonsignificant. CONCLUSION: Although these results are suggestive, a more compelling test is needed of the hypothesis that dopaminergic gene interaction underlies, in part, the likelihood of smoking following treatment with bupropion SR. Most likely this will come from larger studies involving prospective randomization to treatment based on genotype. 相似文献
