What if participants in a one‐trial prisoner's dilemma know before making their decision that the other person has already defected? From the perspective of classic game theory, a dilemma no longer exists. It is clearly in their best interest to defect too. The empathy‐altruism hypothesis predicts, however, that if they feel empathy for the other, then a dilemma remains: self‐interest counsels defection; empathy‐induced altruism counsels not. This motivational conflict should lead at least some empathically aroused individuals not to defect. To test this prediction, we placed 60 undergraduate women in a one‐trial prisoner's dilemma in which they knew the other had already defected. Among those not induced to feel empathy, very few (0.05) did not defect in return. Among those induced to feel empathy for the other, almost half (0.45) did not defect. These results underscore the power of empathy‐induced altruism to affect responses in a prisoner's dilemma. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

The manipulative actions of mountain gorillas Gorilla g. beringei were examined in the context of foraging on hard-to-process plant foods in the field, in particular those used in tackling
thistle Carduus nyassanus. A repertoire of 72 functionally distinct manipulative actions was recorded. Many of these actions were used in several variants
of grip, finger(s) and movement path, both by different individuals and by the same individual at different times. The repertoire
appears somewhat greater than that observed in comparable studies of monkeys, but a far more striking difference is found
in the use of differentiated actions in concert. Mountain gorillas routinely and frequently deal with problems that involve:
(1) bimanual role differentiation, with the two hands taking different roles but synchronized in time and space, and (2) digit
role differentiation, with independent control of parts of the same hand used for separate purposes at the same time. The
independent control that allows these abilities, so crucial to human manual constructional ability, is apparently general
in African great apes. Role differentiation, between and within the hand, is evidently a primitive characteristic in the human
arsenal of skills.

The present study examined traditional family and independence values among young Vietnamese respondents (N = 204), their perceptions of parents' values, and the impact of differential parent-adolescent acculturation on intergenerational conflict and gender satisfaction. The study confirmed that adolescents perceived that they had less traditional values than their parents. Traditional family values diminished with time spent in Australia while the value accorded to independence increased. This pattern was stronger for girls than for boys. Girls valued Vietnamese traditions less than did their male peers, regarded their parents as being less accepting of independence, and were more dissatisfied with their gender role than boys. For girls but not for boys, discrepancy between adolescent and parental values was associated with more conflict and greater gender dissatisfaction. This study suggests that girls have more difficulty than boys in dealing simultaneously with the expectations of two cultures. 相似文献

This paper focuses on the Swiss dual system of vocational education and training (VET), on the basis of the results of a study on VET dropouts. The adopted theoretical framework and method of analysis is the psychodynamic of work, which makes it possible to stress the specific constraints of a system that is closely related to the world of work. The various forms of suffering evoked by apprentices, as well as the strategies implemented to cope with it, are highlighted. The analyses also stress the pleasure young people can experience in VET. Between pleasure and suffering, these elements make it possible to consider both the assets and the shortcomings of this education system. 相似文献

The present study examined whether therapist access to the Minnesota Multiphasic Personality Inventory (MMPI-2) predicted favorable treatment outcome, above and beyond other assessment measures. A manipulated assessment design was used, in which patients were randomly assigned either to a group in which therapists had access to their MMPI-2 data or to a group without therapist access to such information. Illness severity, improvement ratings, number of sessions attended, and premature termination were indicators of therapy outcome. Results indicated that therapist access to the MMPI-2 data did not add to the prediction of positive treatment outcome beyond that predicted by other measures in this setting. Findings from this initial study suggest that, compared with other resources, perhaps in clinical settings with an emphasis on diagnosis-based and evidence-based treatment, the MMPI-2 may not provide incrementally valid information. However, these effects warrant replication across different settings and samples. Guidelines for future studies are discussed. 相似文献

The directed forgetting paradigm involves, under particular experimental circumstances, inhibitory mechanisms, which operate to the successful forgetting of irrelevant words. The item-by-item cueing method (e.g., Basden & Basden, 1996) was used to investigate the directed forgetting effect in young and old adults. Processing of the experimental words was manipulated between subjects by asking participants to perform either a deep or a shallow orienting task on each word of the study list before the occurrence of the cue (to remember of to forget). Results indicated that the instruction to process deeply both to-be-remembered and to-be-forgotten words led to equivalent directed forgetting effects in young and old adults. These results are discussed with respect to the implications they have for the Inhibitory Deficit theory (e.g., Hasher & Zacks, 1988), which suggests that cognitive aging is mainly characterized by a reduction in the efficiency of inhibitory processes. 相似文献

Non-pharmacological behavioral treatments for CFS have been suggested as promising. These trials have tested protocols composed
of behavioral, cognitive and cognitive–behavioral interventions but there have been few efforts to differentially evaluate
their outcomes. The primary purpose of the current study was to evaluate the effectiveness of nurse delivered non-pharmacologic
interventions. In the present study, 114 participants diagnosed with CFS were randomly assigned to four 6-month interventions.
The interventions were: cognitive–behavior therapy, cognitive therapy, anaerobic activity, and a relaxation control group.
The study found that these interventions led to increases in several areas of functioning, with more consistent changes occurring
among those participants in the cognitive condition. For the 25 variables in this study, significant change occurred for 28%,
20%, 16%, and 12% of the variables for the cognitive, cognitive behavior therapy, anaerobic activity, and relaxation conditions,
respectively. However, the majority of participants continued to be diagnosed with CFS following the treatment trial. Implications
of these findings are discussed. 相似文献
