Socioemotional selectivity theory holds that the reliable decline in social contact in later life is due, in part, to older people's preferences for emotionally meaningful social partners and that such preferences are due not to age, per se, but to perceived limitations on time. Confirming the theory, in both the United States and Hong Kong, older people showed a preference for familiar social partners, whereas younger people did not show this preference. However, when asked to imagine an expansive future, older people's bias for familiar social partners disappeared. Conversely, in the face of a hypothesized constraint on time, both younger and older people preferred familiar social partners. Moreover, social preferences in Hong Kong differed before and after the 1997 handover of Hong Kong to the People's Republic of China, which was construed as a sociopolitical time constraint. One year prior to the handover, only older people displayed preferences for familiar partners. Two months before the handover, both age groups showed such preferences. One year after the handover, once again, only older Hong Kong people preferred familiar social partners. 相似文献

Psychopathy and the Five Factor Model in a Noninstitutionalized Sample: A Domain and Facet Level Analysis 总被引:1,自引:0,他引:1

The relationship of primary and secondary psychopathic dispositions as measured by the Levenson Self-Report Psychopathy (LSRP) Scales to NEO-PI-R domain and facet scales of the Five Factor Model (FFM) was examined in a sample (N = 463) of young adults. Previous investigations were extended by (1) addressing the relationship of higher- (i.e., domain) and lower-order (i.e., facet) FFM traits to primary and secondary psychopathy in noninstitutionalized persons, in an attempt to validate hypotheses by T. A. Widiger and D. R. Lynam (1998); (2) examining sex differences in FFM traits in relation to these two psychopathic dispositions; and (3) lending further evidence for the validity of the LSRP. LSRP primary psychopathy was marked by low Agreeableness whereas LSRP secondary psychopathy was characterized by high Neuroticism, low Agreeableness, and low Conscientiousness. Although few sex differences were found between primary and secondary psychopathy, findings support the use of NEO-PI-R domain and facet scales in the identification of personality disorder. 相似文献

Previously, we found that in the lateral amygdala (LA) of the mouse, WIN55,212-2 decreases both glutamatergic and GABAergic synaptic transmission via activation of the cannabinoid receptor type 1 (CB1), yet produces an overall reduction of neuronal excitability. This suggests that the effects on excitatory transmission override those on inhibitory transmission. Here we show that CB1 activation by WIN55,212-2 and Delta(9)-THC inhibits long-term depression (LTD) of basal synaptic transmission in the LA, induced by low-frequency stimulation (LFS; 900 pulses/1 Hz). The CB1 agonist WIN55,212-2 blocked LTD via G(i/o) proteins, activation of inwardly rectifying K+ channels (K(ir)s), inhibition of the adenylate cyclase-protein kinase A (PKA) pathway, and PKA-dependent inhibition of voltage-gated N-type Ca2+ channels (N-type VGCCs). Interestingly, WIN55,212-2 effects on LTD were abolished in CB1 knock-out mice (CB1-KO), and in conditional mutants lacking CB1 expression only in GABAergic interneurons, but were still present in mutants lacking CB1 in principal forebrain neurons. LTD induction per se was unaffected by the CB1 antagonist SR141716A and was normally expressed in CB1-KO as well as in both conditional CB1 mutants. Our data demonstrate that activation of CB1 specifically located on GABAergic interneurons inhibits LTD in the LA. These findings suggest that CB1 expressed on either glutamatergic or GABAergic neurons play a differential role in the control of synaptic transmission and plasticity. 相似文献

419名中国和德国被试参加了本研究,并回答了若干简式心理健康量表。所选的这套量表能对心理治疗不同阶段的效果(Howard’s阶段模型:重新认识期-转变期-康复期)进行测查。本研究目的在于考察这些简式量表能否用于认知-行为治疗跨文化培训项目中的质量管理。结果显示,这些量表在中德两种文化背景下都有很高的信度和效度(聚合效度和敏感性)。尽管项目间的高相关似乎提示心理健康模型只有一个维度,但探索性因素和理论分析则更支持心理健康是一个分为8个亚维度的模型,其中每个亚维度或者与基础情绪、或者与社会性情感相连关联。本文最后就研究结果及其对心理治疗质量控制的意义进行了详细讨论 相似文献

Individuals with synaesthesia experience certain stimuli in more than one sensory modality. Most common is the linkage of letters and digits (graphemes) to colors. Whereas synaesthesia might be partly genetically determined, the linkages to specific colors are assumed to be learned. We present a systematic statistical analysis of synaesthetic color perception based on subjects' reproduction of individual colors for each grapheme, instead of simple verbal categorizations. The statistical analysis revealed that the color perceptions, measured with the HSL (hue, saturation, and luminance) scale, varied systematically among the different digits and letters. The frequencies of the digits and letters (in the German language) partly explained these systematic variations. However, digit frequency was more strongly related to color perception in the synaesthetes than was letter frequency. The results for digit and letter frequency indicate that experience with graphemes may shape synaesthetic color perception. 相似文献

The objective was to examine the association of parental locus of control (PLOC) with pediatric quality of life (QOL) for
children with sickle cell disease (SCD), specifically addressing the potential mediating role of family functioning. Associations
with disease severity were also investigated. Thirty-one primary caregivers completed standard measures of parental locus
of control, family functioning, and quality of life during their child's inpatient admission for pain or fever. Results indicated
that the PLOC total score was significantly associated with QOL in terms of self-competence and showed marginal significance
with QOL social competence; it was significantly negatively correlated with family functioning. The association of the PLOC
with QOL subscales was maintained when controlling for family functioning. Disease severity was not associated with PLOC scores.
Primary caregivers endorsed more external parental locus of control beliefs. Further investigation of the association of caregiver
appraisals and family functioning is warranted with the goal of addressing the stress that disease management with sickle
cell may add to parent–child relationships. 相似文献
