An artificial fruit (AF) was used to test for social learning in pig-tailed macaques (Macaca nemestrina) and adult humans (Homo sapiens). A monkey demonstrator opened the AF, showing alternative methods to 2 groups of cage mates. Video films of the monkey demonstrations were presented to adult humans. Compared with chimpanzees and children, the macaques watched the demonstrations significantly less and in a much more sporadic manner. They also produced only very weak and transitory evidence of social learning. In contrast, the adult humans performed as one might expect of optimum imitators, even producing evidence of components of a "ratchet effect."  相似文献

We assessed the concurrent validity of the Hospital Anxiety and Depression Scale (HADS) and the Geriatric Depression Scale (GDS) against the Hamilton Rating Scale for Depression (Ham-D) in patients with Parkinson's disease (PD). Forty-six non-demented PD patients were assessed by a neurologist on the Ham-D. Patients also completed four mood rating scales: the HADS, the GDS, the VAS and the Face Scale. For the HADS and the GDS, Receiver Operating Characteristics (ROC) curves were obtained and the positive and negative predictive values (PPV, NPV) were calculated for different cut-off scores. Maximum discrimination between depressed and non-depressed PD patients was reached at a cut-off score of 10/11 for both the HADS and the GDS. At the same cut-off score of 10/11 for both the HADS and the GDS, the high sensitivity and NPV make these scales appropriate screening instruments for depression in PD. A high specificity and PPV, which is necessary for a diagnostic test, was reached at a cut-off score of 12/13 for the GDS and at a cut-off score of 11/12 for the HADS. The results indicate the validity of using the HADS and the GDS to screen for depressive symptoms and to diagnose depressive illness in PD.  相似文献

We investigated (in 95 Italians aged 19–29, of both genders, and who were all facing the transition to job): (1) the relationships between job precariousness, life satisfaction (LS), and the perception that the reality is comprehensible, manageable and meaningful (sense of coherence—SOC—Antonovsky 1987); (2) the potential buffering effect of SOC versus job precariousness on LS. The findings showed that (a) young adults with a higher level of education perceive less LS and higher manageability, and youths with a precarious job perceive reality as less controllable, manageable and meaningful; (b) manageability is positively related with satisfaction with close relationships and meaningfulness is positively related with LS in general; (c) meaningfulness also buffers the effect of job precariousness on satisfaction for close relationships; among precarious workers there is a curvilinear relationship with LS: youths with intermediate meaningfulness also show higher LS with respect to both low and high meaningfulness.  相似文献

We explored the phenomenon of the transition to adulthood, focusing on how young people cope with various developmental tasks in relation to their expectations, future projects, fears and indecision in two Italian regional areas characterized by different trends in youth employability, higher educational attainment and family formation process. We measured self-perceived adulthood, self-reported satisfaction, independence, perceived support regarding personal relationships and practical and economical issues, personal projections and future life’s choices. We also explored the perception of self-fulfillment for the future concerning personal goals in life, such as in the spheres of work, studies and economic autonomy together with expectations for the quality of personal relationships. One hundred and sixty nonworking university students (M age = 22.6; SD = 2.77; range = 19–35) from the Universities of Turin and Palermo took part in this study. Sub-groups differed on self-perceived adulthood, self-reported satisfaction, independence, perceived support and self-fulfillment. Psychological and economic independence from the family of origin was most perceived by the participants from Turin who reported a higher degree of satisfaction regarding their choice of studies and their future perspective of self-fulfillment at work. Young people from Palermo highlighted personal relationships as an important source of perceived support.  相似文献

Acts of civil disobedience and conscientious objection provide valuable indications of the congruence of political outcomes with citizens’ conceptions of justice and the good. As their primary concern is substantive, their logic seems extraneous to procedural approaches to justice. Accordingly, it has often been argued that these latter condemn citizens to a ‘deaf-and-blind’ acceptance of the outcomes of agreed procedures. A closer analysis of such acts of contestation shall reveal that although, for proceduralism, the outcomes of just procedures cannot be contested as unjust, they may be contested on the ground of values other than justice, such as someone’s religious/ethical allegiances. Proceduralism about justice will be thus shown to be consistent with the commitment to realising certain outcome-oriented values.  相似文献

People often discuss events they have seen and these discussions can influence later recollections. We investigated the effects of factual, emotional, and free retelling discussion on memory recollections of individuals who have witnessed an event. Participants were shown a video, made an initial individual recall, participated in one of the three retelling conditions (emotional versus factual versus free) or a control condition, and then recalled the event individually again. Participants in the factual and free retelling conditions reported more items not previously recalled than participants in the control condition did, while the emotional condition did not show the same advantage. Participants in all three retelling conditions failed to report more previously recalled items as compared with the control condition. Finally, a memory conformity effect was observed for all three retelling conditions. These findings suggest that eyewitnesses’ discussions may influence the accuracy of subsequent memory reports, especially when these discussions are focused on emotional details and thoughts.  相似文献
