Correspondences among pupillary dilation response,subjective salience of sounds,and loudness

A pupillary dilation response is known to be evoked by salient deviant or contrast auditory stimuli, but so far a direct link between it and subjective salience has been lacking. In two experiments, participants listened to various environmental sounds while their pupillary responses were recorded. In separate sessions, participants performed subjective pairwise-comparison tasks on the sounds with respect to their salience, loudness, vigorousness, preference, beauty, annoyance, and hardness. The pairwise-comparison data were converted to ratings on the Thurstone scale. The results showed a close link between subjective judgments of salience and loudness. The pupil dilated in response to the sound presentations, regardless of sound type. Most importantly, this pupillary dilation response to an auditory stimulus positively correlated with the subjective salience, as well as the loudness, of the sounds (Exp. 1). When the loudnesses of the sounds were identical, the pupil responses to each sound were similar and were not correlated with the subjective judgments of salience or loudness (Exp. 2). This finding was further confirmed by analyses based on individual stimulus pairs and participants. In Experiment 3, when salience and loudness were manipulated by systematically changing the sound pressure level and acoustic characteristics, the pupillary dilation response reflected the changes in both manipulated factors. A regression analysis showed a nearly perfect linear correlation between the pupillary dilation response and loudness. The overall results suggest that the pupillary dilation response reflects the subjective salience of sounds, which is defined, or is heavily influenced, by loudness.     

抑郁症状阳性人群的初始沙盘特征

采用病例对照研究设计,探讨抑郁症状阳性人群初始沙盘特征。结果显示：抑郁症状阳性组在总数、动物、人物、建筑物、交通工具、植物类沙具使用少于对照组;抑郁症状阳性组沙盘空间领域使用少于对照组;抑郁症状阳性组在从哪里开始、对沙的态度、有无蓝色露底、是否使用桥、自己感觉是否满意、自我像是否在其中和主题场景上与对照组比较差异有统计学意义;沙盘主题特征回归分析显示进入抑郁症状阳性回归方程的沙盘主题特征变量有忽视、威胁、流动和能量。抑郁症状阳性人群在沙盘游戏中有特征性表现,初始沙盘具有临床心理评估的功能和价值。

Minorities remember more: the effect of social identity salience on group-referent memory

Research on the group-reference effect has confirmed that social identities can affect memory, but few studies have explored the role of identity salience in this effect. Two experiments were designed to fill the gap. In Experiment 1 Tibetan students at one predominantly Han Chinese university showed high ethnic identity salience and better memory for trait adjectives encoded in reference to Tibetans than in reference to Han Chinese. In Experiment 2 Tibetan students at one Tibetan-majority university demonstrated low ethnic identity salience and no differences were found between memory performance under Tibetan-referential processing and Han-referential processing conditions. In comparison, Han participants did not show high ethnic awareness or an ingroup-reference effect in either experiment, due to membership of an ethnic majority (Experiment1) and lack of inter-ethnic contact (Experiment 2). These findings suggest that high salience is a prerequisite for social identities to facilitate memory.     

Referral Source Differences in Functional Impairment Levels for Children Served in the Comprehensive Community Mental Health Services for Children and Their Families Program

We report one of the first multi-site investigations into referral source variation in functional impairment for children with serious emotional disturbance served in systems of care settings. Baseline data collected as part of the national evaluation for the Comprehensive Community Mental Health Services for Children and Their Families Program was used to assess the comparability of functional status for children referred from traditional mental health versus non-mental health agencies. Results indicate that children referred from child welfare and family groups have significantly lower levels of overall dysfunction than those referred from mental health, while children referred from school and juvenile justice agencies have comparable levels. Clinical and research implications are discussed.     

移动医疗视域下HIV/AIDS患者自我管理体验及需求的质性研究

激活右腹外侧前额叶提高抑郁症患者对社会疼痛的情绪调节能力：一项TMS研究

负性人际交往经历和负性社会事件是抑郁症的重要诱导因素, 而社会功能受损是抑郁症患者的重要特征之一, 患者通常表现出对社会疼痛的情绪失调。为了提高抑郁症患者在负性社交情境中或面对负性社会事件时的情绪调节能力, 本研究采用经颅磁刺激技术(transcranial magnetic stimulation, TMS), 考察抑郁症患者在腹外侧前额叶(the ventrolateral prefrontal cortex, VLPFC)被激活后其情绪调节能力的改变。结果表明, 当右侧VLPFC被TMS激活且患者采用认知重评策略调节情绪时, 实验组患者(n = 64)比对照组患者(n = 63)在社会排斥情境下报告了更弱的负性情绪体验, 这说明激活右侧VLPFC可以有效提高患者对社会疼痛的外显性情绪调节能力。本研究是采用TMS提高抑郁症患者情绪调节能力的首次尝试, 实验发现不但支持了VLPFC与认知重评策略的因果关系, 还为临床改善抑郁症等社会功能障碍患者的情绪调节能力提供了明确的神经治疗靶点。后续研究还需探讨多疗程TMS刺激方案、改变社会疼痛的诱发方式、对比左右侧VLPFC的治疗效果、尝试使用其他的情绪调节策略, 进一步验证本研究的结论, 优化TMS治疗方案。     

背外侧前额叶对主动遗忘负性社会反馈的作用：针对抑郁症的TMS研究

抑郁症患者的负性心境可能源于其抑制功能障碍。患者在主动遗忘负性材料时无法有效调用背外侧前额叶(the dorsolateral prefrontal cortex, DLPFC)等负责抑制控制的额叶脑网络。同时, 患者对社会信息的加工比对非社会信息的加工存在更明显的认知神经障碍, 很难主动遗忘对自己不利的社会反馈信息。为了提高抑郁症患者对负性社会反馈的主动遗忘能力, 本研究采用经颅磁刺激技术(transcranial magnetic stimulation, TMS), 考察抑郁症患者在左侧(n = 32)或右侧DLPFC (n = 30)被激活后其记忆控制能力的改变。结果表明, 当患者的DLPFC被TMS激活时, 他们对社会拒绝的回忆正确率与健康对照组(n = 31)无差异, 且TMS激活右侧DLPFC还改善了患者对他人的社会态度。本研究是采用TMS提高抑郁症患者主动遗忘能力的首次尝试, 研究结果不但支持了DLPFC与记忆控制功能的因果关系, 还为临床治疗抑郁症、创伤后应激障碍、药物成瘾等患者的记忆控制缺陷提供了明确的神经靶点。     

视觉空间工作记忆组间差异的神经机制

为考察视觉空间工作记忆（working memory, WM）维持和操作的组间差异及其神经机制,本研究记录了高、低WM组完成延迟再认（维持）任务和心理旋转（操作）任务时的行为和事件相关电位数据。结果发现,在操作任务中,高WM组比低WM组的反应时显著更短;高WM组的中前额叶慢波显著更正、双侧后顶区慢波显著更负,并且两者的波幅显著负相关。在维持任务中,两组被试的反应时无显著差异;高WM组的中前额叶慢波显著更正。结果表明,高WM组的执行注意能力可能更强,能通过有效调节和分配加工资源来表征视觉信息。     

二胎环境下小学高年级“脱独”儿童父母教养方式与同胞关系:心理理论的中介作用

研究采用问卷集体施测,收集了788名小学高年级“脱独”儿童的父母教养方式、同胞关系以及心理理论的状况,探讨小学高年级“脱独”儿童父母教养方式对同胞关系的影响及心理理论作为中介变量的影响。结果表明:心理理论在父母教养方式中的父亲过分干涉、母亲情感温暖理解、母亲惩罚严厉、母亲过分干涉与同胞关系之间起完全中介作用; 心理理论在父亲情感温暖理解、父亲偏爱与同胞关系之间起部分中介作用。研究认为,良好的父母教养方式,有助于个体提高心理理论,并可能在一定程度上改善同胞关系。
