To trust or not to trust: social decision‐making in post‐institutionalized,internationally adopted youth 下载免费PDF全文

Chronic parental maltreatment has been associated with lower levels of interpersonal trust, and depriving environments have been shown to predict short‐sighted, risk‐averse decision‐making. The present study examined whether a circumscribed period of adverse care occurring only early in life was associated with biases in trust behavior. Fifty‐three post‐institutionalized (PI) youth, adopted internationally on average by 1 year of age, and 33 never‐institutionalized, non‐adopted youth (Mage = 12.9 years) played a trust game. Participants decided whether or not to share coins with a different anonymous peer in each trial with the potential to receive a larger number of coins in return. Trials were presented in blocks that varied in the degree to which the peers behaved in a trustworthy (reciprocal) or untrustworthy (non‐reciprocal) manner. A comparison condition consisted of a computerized lottery with the same choices and probabilistic risk as the peer trials. Non‐adopted comparison youth showed a tendency to share more with peers than to invest in the lottery and tended to maintain their level of sharing across trials despite experiencing trials in which peers failed to reciprocate. In contrast, PI children, particularly those who were adopted over 1 year of age, shared less with peers than they invested in the lottery and quickly adapted their sharing behavior to peers’ responses. These results suggest that PI youth were more mistrusting, more sensitive to both defection and reciprocation, and potentially more accurate in their trusting decisions than comparison youth. Results support the presence of a sensitive period for the development of trust in others, whereby conditions early in life may set long‐term biases in decision‐making. 相似文献

Associations between behavioral inhibition and activity of the hypothalamic-pituitary-adrenocortical (HPA) system, a stress-sensitive neuroendocrine system indexed by salivary cortisol, have varied widely across studies. In the current study, we examined the role of peer social experiences in moderating patterns of association between inhibition/risk-aversion and cortisol reactivity. As expected based on previous research, preschool children (N = 165, 78 boys, 87 girls, 3.0-5.0 years) had significantly different social experiences in their preschool classrooms depending on temperament. Highly inhibited/risk-averse children were less socially integrated, less dominant, and less involved in aggressive encounters than both average and highly exuberant/risk-seeking children, but they were no more likely to be peer rejected. Highly exuberant children were more dominant, exhibited anger more often, and had friendships characterized by higher conflict. Cortisol levels fell from fall to spring for average and highly exuberant children but not for highly inhibited children. Unexpectedly, for highly inhibited children, having friends and being more dominant and popular than other highly inhibited children was associated with increasing cortisol levels over the school year. In contrast, highly exuberant children who were less socially integrated than other highly exuberant children maintained higher cortisol levels. Results indicate that the types of social experiences that affect stress-responsive biological systems may differ markedly for highly inhibited and highly exuberant children. 相似文献

The purpose of this investigation was to examine longitudinally gestational age and developmental differences in preterm infants' self-regulatory abilities in response to a painful stressor, as well as associations between behavioral and cardiovascular responses. Participants included 49 healthy premature infants. Behavioral and cardiovascular responses to a heel stick blood draw were compared between infants of 28-31 and 32-34 weeks' gestation age at birth. Both gestational age groups displayed behavioral and cardiovascular indications of stress in response to the blood draw. However, both shortly after birth and several weeks later, infants born at younger gestational ages (28-31 weeks) were more physiologically reactive. Evidence that the behavioral stress responses of 28-31 weeks' gestation age group preterm infants do not reflect their physiological responses suggests that evaluation of preterm infants' experiences and risk require assessments of both physiology and behavior. The greater stress vulnerability of the 28-31 weeks' gestation group relative to the 32-34 weeks' gestation group and the implications of this for subsequent development are discussed. 相似文献

The aim of the present study was to examine the effectiveness of manual-guided cognitive-behaviour therapy (CBT) for childhood obsessive-compulsive disorder (OCD) administered within three regular, i.e., non-academic, Norwegian outpatient child psychiatric clinics. METHODS: A total of 28 youngsters, aged 8-17 with primary OCD entered the study. Assessment at intake included Norwegian versions of the K-SADS-PL, Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS), and a measure of OCD-specific functional impairment (Child OCD Impact Scale (COIS)). Therapy consisted of 12 manual-guided sessions with combined individual and family CBT-based interventions and was conducted by psychologists and physicians under training and supervision. Outcome was assessed after treatment and at 3- and 6-month follow-ups by means of the CY-BOCS, the Clinical Global Impression (CGI) and the CGI-Improvement scales, and the COIS. RESULTS: Twenty-four youngsters (86%) completed treatment and were available for the follow-up assessments. Significant improvements were found on all outcome measures after treatment, including a mean symptom reduction on the CY-BOCS of 60.6%, increasing to 68.8% at the 6-month follow-up. Estimates of within-group effect sizes showed strong effects of treatment. CONCLUSION: The results of the present study suggest that manual-guided CBT for childhood OCD can be successfully implemented in non-academic community child psychiatric settings with outcomes in accordance with previous findings from highly specialised university clinics. 相似文献

Most Norwegians are Internet users. We conducted a stratified probability sample study (Norway, 2007, age-group 16–74 years, N = 3,399, response rate 35.3%, 87.1% Internet users) to assess the prevalence of Internet addiction and at-risk Internet use by the Young Diagnostic Questionnaire (YDQ). The prevalence of Internet addiction (YDQ score 5–8) was 1.0% and an additional 5.2% were at-risk Internet users (YDQ score 3–4). Internet addiction and at-risk Internet use was strongly dependent on gender and age with highest prevalences among young males (16–29 years 4.1% and 19.0%, 30–39 years 3.3% and 10.7%). Logistic regression showed that male gender, young age, university level education, and an unsatisfactory financial situation were factors positively associated with "problematic Internet use" (at-risk and addicted use combined). Time spent on the Internet and prevalence of self-reported sleeping disorders, depression, and other psychological impairments increased linearly with YDQ score. Problematic Internet use clearly affects the lives of many people. 相似文献

This study aims at discovering the essential constituents involved in the experiences of guilt and shame. Guilt concerns a
subject’s action or omission of action and has a clear temporal unfolding entailing a moment in which the subject lives in
a care-free way. Afterwards, this moment undergoes a reconstruction, in the moment of guilt, which constitutes the moment
of negligence. The reconstruction is a comprehensive transformation of one’s attitude with respect to one’s ego; one’s action;
the object of guilt and the temporal-existential experience. The main constituents concerning shame are its anchorage in the
situation to which it refers; its public side involving the experience of being perceptually objectified; the exclusion of
social community; the bodily experience; the revelation of an undesired self; and the genesis of shame in terms of a history
of frozen now-ness. The article ends with a comparison between guilt and shame. 相似文献

Several driving simulators have been developed which range in complexity from PC based driving tasks to advanced "real world" simulators. The AusEd driving simulator is a PC based task, which was designed to be conducive to and test for driver fatigue. This paper describes the AusEd driving simulator in detail, including the technical requirements, hardware, screen and file outputs, and analysis software. Some aspects of the test are standardized, while others can be modified to suit the experimental situation. The AusEd driving simulator is sensitive to performance decrement from driver fatigue in the laboratory setting, potentially making it useful as a laboratory or office based test for driver fatigue risk management. However, more research is still needed to correlate laboratory based simulator performance with real world driving performance and outcomes. 相似文献

This paper purports to enhance the understanding of stress and its effects on unemployed executives. The idea that unemployed managers perceive and confront stress differently from their employed colleagues is addressed. A sampling of 32 unemployed executives and managers was taken using The Stress Profile, to survey reasons for stress, coping ability, and response to stress. The profiled samples were then compared to a comparison group of 367 employed managers. The results showed that unemployed managers, when compared to their employed associates, tended to have less desireable family situations, more worries about finances, decreased perception of self and self-coherence, decreased coping ability, and heightened emotional and behavioral reaction to stress. The conclusion was that when dealing with stressors, unemployed managers experienced a decreased sense of psychological well-being and coping abilities as compared to employed managers. 相似文献
