Recollections of Childhood Sexual Abuse: Complexities of Religious Coping and Muslim Religious and Psychological Adjustment in Afghanistan

Are mindful people more risk-averse? Effects of trait and state mindfulness on risk preference in decision-making

The current research investigated whether various aspects of mindfulness were differentially associated with risk preference in decision-making. In Studies 1 and 2, attention and present-focus aspects of trait mindfulness were associated with lower risk preference in making monetary gains. In Study 3, participants completed either a mindfulness training or listened to a comparable control recording. Compared to the control condition, subjects in the mindfulness condition were more risk-averse in making choices for monetary gains. The attention and present-focus aspects of state mindfulness mediated this connection. Study 4 introduced a loss framing, where attention and present-focus no longer associated with lower risk preference, but awareness and acceptance aspects of trait mindfulness associated with higher risk preference in avoiding monetary losses. The results suggest that different aspects of mindfulness have potential for mitigating risk preference, but such potential is limited depending on the framing of a decision context.     

On the Respective Roles of Nitric Oxide and Carbon Monoxide in Long-Term Potentiation in the Hippocampus

Perfusion of hippocampal slices with an inhibitor of nitric oxide (NO) synthase-blocked induction of long-term potentiation (LTP) produced by a one-train tetanus and significantly reduced LTP by a two-train tetanus, but only slightly reduced LTP by a four-train tetanus. Inhibitors of heme oxygenase, the synthetic enzyme for carbon monoxide (CO), significantly reduced LTP by either a two-train or four-train tetanus. These results suggest that NO and CO are both involved in LTP but may play somewhat different roles. One possibility is that NO serves a phasic, signaling role, whereas CO provides tonic, background stimulation. Another possibility is that NO and CO are phasically activated under somewhat different circumstances, perhaps involving different receptors and second messengers. Because NO is known to be activated by stimulation of NMDA receptors during tetanus, we investigated the possibility that CO might be activated by stimulation of metabotropic glutamate receptors (mGluRs). Consistent with this idea, long-lasting potentiation by the mGluR agonist tACPD was blocked by inhibitors of heme oxygenase but not NO synthase. Potentiation by tACPD was also blocked by inhibitors of soluble guanylyl cyclase (a target of both NO and CO) or cGMP-dependent protein kinase, and guanylyl cyclase was activated by tACPD in hippocampal slices. However, biochemical assays indicate that whereas heme oxygenase is constitutively active in hippocampus, it does not appear to be stimulated by either tetanus or tACPD. These results are most consistent with the possibility that constitutive (tonic) rather than stimulated (phasic) heme oxygenase activity is necessary for potentiation by tetanus or tACPD, and suggest that mGluR activation stimulates guanylyl cyclase phasically through some other pathway.

皮质醇日常节律与儿童问题行为及心理社会因素的关系

HPA轴(下丘脑?垂体?肾上腺皮质轴, hypothalamic-pituitary-adrenal cortex axis)是人体应对压力的重要神经内分泌系统, 其终产物皮质醇常作为测量压力的生物学指标。目前的研究多通过皮质醇日常节律表示静息状态下HPA轴的活动, 而日常节律因其较高的稳定性和可靠性成为儿童生理健康评估的最佳指标。儿童期迅速发育的神经内分泌系统与儿童的行为相互作用, 并受到多种心理社会因素的影响。以往研究主要关注皮质醇日常节律与儿童问题行为及心理社会因素的关系, 未来研究应讨论逆境条件下影响儿童成长的危险性因素和保护性因素, 并探索环境对儿童行为影响可能存在的内分泌机制。     

冷酷无情特质：一种易于暴力犯罪的人格倾向

冷酷无情特质(callous unemotional trait, CU)是指对他人冷漠、缺乏罪责感、低共情的一种人格倾向, 伴随有高频率和高破坏性的反社会行为甚至暴力犯罪。CU特质者在情感上表现为对负性情绪加工不敏感, 缺乏共情; 在认知上表现出追求奖赏、忽视惩罚; 在生物学方面, CU特质者生理唤醒水平低、皮质醇水平低、杏仁核和腹内侧前额叶活动异常。未来研究的方向是修订发展本土化CU特质量表、探析CU特质者的性别差异、梳理CU与品行障碍等其他精神障碍的关系、为暴力犯循证矫正的方案设计提供科学依据。     

Differentiating religious coping from Islamic identification in patient and non-patient Pakistani Muslims

Pakistanis suffering from major medical problems and non-patient controls responded to two factors from the Psychological Measure of Islamic Religiousness that operationalised religious coping. Punishing Allah Reappraisal correlated positively with Poorer Psychological Functioning and External Control and negatively with Self-Adjustment. Factor analytic procedures demonstrated that the Islamic Positive Religious Coping and Identification subscale (IPRCIS) contained three dimensions. These Positive Islamic Coping, Islamic Identification, and Extra-Prayer Commitment factors displayed similar linkages with single-item measures of religious orientation and religious interest. Positive Islamic Coping also had noteworthy implications for understanding Muslim religious coping. These data most importantly demonstrated that the IPRCIS is a multidimensional construct, that Punishing Allah Reappraisal is maladaptive, and that the influences of beneficial Muslim forms of coping may be complex.     

Core structure of a〈100〉 superdislocations in a single-crystal superalloy during high-temperature and low-stress creep

A thorough TEM analysis has been carried out to study the dislocations cutting into γ′ phase in a single-crystal superalloy during uniaxial tensile creep under high-temperature and low-stress conditions. It is proved that the a〈100〉 edge superdislocation originates from the interfacial a〈100〉 dislocations and moves into the γ′ phase by pure climbing. And the dissociation of the a〈100〉 superdislocation core into two a/2〈101〉 superpartial dislocations during uniaxial tensile creep has been identified by HRTEM method for the first time.
