Network and mutual support for parents bereaved following the violent deaths of their 12- to 28-year-old children: A longitudinal,prospective analysis

Abstract

Social support provided by bereaved parents' networks was examined in this study. Seven dimensions of support were assessed over time. Of special interest to the investigators were the types and frequency of posttreatment contacts among bereaved parents who participated in an experimental support program. The study compared those who reported high versus low social support and high versus low numbers of network confidants on selected outcome and coping variables. The authors recruited a community-based sample of 171 bereaved mothers and 90 bereaved fathers whose 12- to 28-year-old children had died by accident, suicide, or homicide 4 months previously. Parents were randomly assigned to a 12-week bereavement program or control group. It was expected that intervention group parents would report more social network in involvement and greater satisfaction with support received than control group parents. This hypothesis was only partially supported. Only 20% of the parents who participated in the bereavement program remained in contact after the experimental program ended. Finally, significant differences detected between parents who reported high and low support were minimal and not sustained over time. The number of network confidants did not significantly affect the outcomes examined. However, in general, those with more confidants reported lower symptoms. Additional studies are needed to address these complex issues.     

The association of environmental,individual factors,and dopamine pathway gene variation with smoking cessation

This study aimed to examine whether dopamine (DA) pathway gene variation were associated with smoking cessation, and compare the relative importance of infulence factors on smoking cessation. Participants were recruited from 17 villages of Shandong Province, China. Twenty-five single nucleotide polymorphisms in 8 DA pathway genes were genotyped. Weighted gene score of each gene was used to analyze the whole gene effect. Logistic regression was used to calculate odds ratios (OR) of the total gene score for smoking cessation. Dominance analysis was employed to compare the relative importance of individual, heaviness of smoking, psychological and genetic factors on smoking cessation. 415 successful spontaneous smoking quitters served as the cases, and 404 unsuccessful quitters served as the controls. A significant negative association of total DA pathway gene score and smoking cessation was observed (p < 0.001, OR: 0.25, 95% CI 0.16–0.38). Dominance analysis showed that the most important predictor for smoking cessation was heaviness of smoking score (42%), following by individual (40%), genetic (10%) and psychological score (8%). In conclusion, although the DA pathway gene variation was significantly associated with successful smoking cessation, heaviness of smoking and individual factors had bigger effect than genetic factors on smoking cessation.     

On recognition and self: a discussion based on Nyāya,Mīmāṃsā and Buddhism

The phenomenon of recognition is a point of contention in the debate between the orthodox Hindus and Buddhists on whether the self (ātman) exists. The Hindus, including Naiyāyikas and Mīmā?sakas, argue that recognition evidences the existence of the self, while Buddhist philosopher ?āntarak?ita maintains that there is no self and recognition should be explained in another way. This article examined two disputes, focusing on the two subsidiary aspects of a recognition: memory and self-recognition. For Hindus, it is the existence of the self that makes memory and self-recognition possible. For Buddhists, it is due to the phenomena of memories and self-recognitions that people postulate the existence of the self. I argue that Buddhist explanation of memory is more acceptable, while their debates on self-recognition should be considered as a tie.     

女大学生体重知觉偏差及探因

以女性身体图形评定量表PFRS (the female Photographic Figure Rating Scale)作为刺激材料, 研究女大学生体重自我知觉与偏差, 以及女大学生对他人的体重知觉与偏差, 引入男性视角作为体重社会标准, 研究女大学生体重社会知觉与偏差。研究中要求女大学生选择准确代表自己胖瘦的图像, 选择自己理想胖瘦的图像, 选择他人眼里最有吸引力的图像, 估计PFRS真人照片图像体重值(假定图像中人物和自己身高相同), 并报告自己的实际体重和理想体重。研究要求男大学生选择最有吸引力的图像。在此基础上提出3种模型假设：镜像模型、泛化模型和相关模型, 进一步探索女大学生体重知觉偏差的原因。研究表明：女大学生体重自我知觉高估了对应真人图像的BMI; 女大学生对其他女性BMI知觉, 倾向于高估体重正常和偏瘦女性的BMI, 低估偏胖和肥胖女性的BMI; 女大学生体重的主观社会压力高于体重的实际社会压力, 对体重社会压力存在过度解读的倾向。女大学生对他人体重知觉偏差更有可能影响其体重自我知觉偏差; 认知评价不是造成女大学生知觉偏差的重要因素, 但两者关系需要进一步实证。     

汉语句子加工中句法信息与语义信息的交互作用：来自ERP的证据

采用ERP技术考察句子加工过程中句法信息和语义信息交互作用的时间进程。以汉语“把字句”为实验材料,分别比较句法违例句与双重违例句的LAN和P600效应、语义违例句与双重违例句的N400效应。与句法违例句相比,双重违例句的LAN效应的波幅更负,潜伏期更长,皮层分布更广泛;双重违例句的P600效应出现减弱趋势;双重违例句的N400效应的潜伏期显著长于语义违例句。结果表明,在句子加工的各个阶段,句法信息和语义信息呈持续交互作用,支持句子的平行加工模型。     

Kinematics, kinetics, and electromyogram of ankle during drop landing: a comparison between dominant and non-dominant limb

The biomechanical difference between the dominant and non-dominant limb has seldom been studied during double-leg landing. The objective of this study was to evaluate the effectiveness of limb laterality on the ankle kinematics, kinetics and electromyogram (EMG) during drop landing. Sixteen healthy adults were recruited and dropped individually from platforms with three different heights (0.32 m, 0.52 m, and 0.72 m). The ground reaction force, ankle joint kinematics, and surface EMG of tibialis anterior (TA) and lateral gastrocnemius (LG) were measured in both lower extremities. Two-way analysis of variance was used to analyze the effects of laterality and dropping height. The peak angular velocities in dorsiflexion and abduction were significantly higher in the dominant ankle, whereas the pre- and post-landing EMG amplitudes of the TA were significantly higher in the non-dominant limb. Compared with the dominant side, the non-dominant ankle has a more effective protective mechanism in that excessive joint motion is restrained by greater ankle flexor activity. Compared with the non-dominant side, the dominant ankle joint is in greater injury risk during drop landing, and data measured in the dominant limb may produce more conservative conclusions for injury protection or prediction.     

中国人三重自我建构加工中的相对优先性:来自ERP的证据

借助事件相关电位技术,采用启动范式的变式探讨了中国人三重自我建构的加工特点。结果发现,具体哪种自我建构占据加工优势取决于具体的加工阶段:早期加工阶段集体自我占加工优势;晚期加工阶段个体自我占加工优势;而在N2成分上,三种自我建构加工优势相当。该结果在一定程度上支持了情境性假设,拓展了三重自我建构理论的研究,为该领域的理论争论提供了新的认知神经科学证据。     

中国人诚实-谦虚人格的特点及其内隐外显关系

诚实-谦虚是重要的人格维度。研究一基于词汇假设法提出诚实包括坦诚、不欺骗、不狡猾、不虚伪等因子,谦虚包括自谦、不浮夸、不自傲、不虚荣等因子,证实中国人的诚实、谦虚相互独立且高相关。研究二通过问卷调查法发现：(1)诚实在性别、户籍上存在显著差异,谦虚在性别、是否独生子女上存在显著差异;(2)诚实对情绪智力、积极应对方式、追求成功动机有显著的正向预测作用,诚实对消极应对方式有显著的负向预测作用;(3)谦虚对追求成功动机有显著的负向预测作用。研究三采用内隐联想测验证实了内隐诚实、内隐谦虚的存在并且内隐外显相互分离。研究表明：中国人的诚实-谦虚人格为一阶8因子、二阶2因子的结构,诚实可以有效预测个体的情绪智力、应对方式和追求成功动机,谦虚可以有效预测个体追求成功动机,诚实、谦虚存在内隐效应且内隐外显之间相互分离。     

内倾特质个体的自我参照加工程度效应

采用事件相关电位技术和三类刺激的经典oddball范式,以内隐的方式探讨内倾特质个体的自我参照加工程度效应及其神经机制。实验发现,在P2的波幅上,在电极前部、前中部和中部位置高自我相关的刺激比其它刺激诱发了更大的P2波幅。在P2的潜伏期上,在电极前部、中部、和中后部位置高自我相关的刺激比其它刺激诱发了更短的潜伏期。在N2的波幅上,高自我相关名字比其它刺激在左脑所诱发了更大的P2的波幅;对比内倾型被试,中间型被试的高自我相关名字比其它刺激诱发了更大的N2的波幅。在N2的潜伏期上,高自我相关的刺激在全脑都比其它刺激诱发了更短的N2潜伏期,且中后部电极位置的潜伏期最短;两类人格被试的高自我相关名字比其它刺激诱发了更短的N2潜伏期,但中间型人格被试的潜伏期最短。在P3平均波幅上,高自我相关的刺激在全脑都比其它刺激诱发了更大的P3波幅,其中中部脑区效应最大。研究结果表明内倾特质个体的自我参照加工具有程度效应,但对比中间型个体,内倾特质个体的自我参照加工的程度效应更弱。
