　　报告题目：Electrophysiological evidence for the effects of unitization on associative recognition memory in older adults

　　报告摘要： 

　　Normal aging is associated with greater declines in associative memory relative to item memory, which may result from impaired recollection. It has been demonstrated recently that familiarity may also contribute to associative recognition when stimuli are perceived as a ‘unitized’ representation. Owing to an understanding that familiarity is relatively preserved in older adults, we explored whether aging-related associative memory deficits could be attenuated when encoded associations were unitized. Retrieval processes associated with familiarity and recollection were measured using event-related potentials (ERPs). In an associative recognition task, 25 young and 24 older adults studied Chinese language two-character compound words and unrelated word pairs. Subsequently, participants were asked to decide whether a presented character pair was intact, rearranged, or new relative to the studied character pairs while electroencephalograms (EEGs) were recorded. Behavioral results showed that age differences were smaller for associative recognition of compound words than for unrelated word pairs. Electrophysiological results indicated that only compounds evoked early frontal old/new effect, and left parietal old/new effect is greater for compounds than for unrelated word pairs in older adults. Mid-frontal, left parietal, and late right frontal old/new effects for compound words, but not for unrelated word pairs, showed no age differences. These findings suggest that unitization could alleviate age-related associative deficits through enhanced familiarity and recollection-based retrieval processes during associative recognition in older adults.

　　报告题目：Facial reactions to situations of other's real-life pain

　　报告摘要：　　Empathy, a basic social cognitive function, plays a vital role in everyone's daily life. A growing body of research reveals that people mimic the emotional facial expression in the context of emotional empathy, e.g., facial expression of anger and happiness elicit corresponding frowns and smiles. There is a dearth of studies examining the facial behaviors in empathy for pain, however. The present study focused on the expression changes as empathic reaction towards situations of other's real-life pain. Highly ecological validity video clips were prerecorded depicting people being injected (n=10, 4 males). The control video clips were recorded from additional 10 subjects showing neutral expressions with arms being wiped by a Q-tip. Thirty-four graduate and undergraduate subjects (males 11, age 20.9±2.2) participated in this experiment. Facial electromyography (EMG), electrodermal activity (EDA) and pulse rate were recorded to assess the emotional responses elicited by visual stimuli. Subjective ratings of pain intensity and unpleasantness as well as interpersonal reactivity index (IRI) were measured after the termination of video stimuli. The results showed that, compared to the neutral videos, viewing pain videos elicited more corrugator activity and more zygomaticus activity as well. The activities of these facial muscles have consistently been attributed to the facial expression of pain. Furthermore, corrugators activity correlated positively to scores of empathic concern subscale of IRI, while zygomaticus activity correlated negatively to IRI scores. These results suggest that observing others in pain may lead to painful facial expression of the observer, and people with higher trait empathy are more facially reactive to others’ suffering.

　　报告题目：帕金森症患者的肠道菌群状况分析

　　报告摘要：PD是常见的中老年神经退行性病变之一，早期发现和诊断对控制该病的进程具有重要意义。临床研究发现，PD患者常常伴随着消化道的慢性炎症、长期便秘等非运动症状，这些都提示PD可能肠道菌群失调有关。肠道的健康状况及肠道菌群特征可能成为早期筛查PD的一个风险标志。近年来，有研究表明肠道共生微生物可以显著改善肠道易激的状态，并通过脑-肠轴调节大脑的多巴胺系统，从而可能成为预防和治疗PD的有效方法。本研究拟通过对PD患者的饮食习惯、认知能力、心理特征进行问卷调查，并针对其肠道菌群特征进行分析，试图从肠道菌群和肠脑的角度探讨PD的发病原因，以及使用安全的益生菌对PD患者进行生物学干预的可行性。

报告题目：长寿心理商数的定义、影响因素及其测量

报告摘要：
　　长寿研究表明成功的老龄化和存活率差异是生物、社会、心理因素共同作用的结果，其中个体心理行为因素对寿命的影响作用超过60%。报告首先回顾了影响长寿的行为和心理因素（包括情绪、人格、健康行为、应对机制等）、生物学因素（包括遗传、性别、种族和生理因素）、社会因素、以及心理行为因素与生物学因素的交互作用。这些研究通常将生存时间作为长寿指标，采用纵向追踪的方法探讨一个或几个因素对长寿的作用，但却没有长寿心理影响因素的整合模型研究。其次，为了能够客观、量化评估与表述，并进一步预测个体受心理因素影响的长寿水平，我们提出了长寿心理商数（LPQ）的概念并对其进行操作化定义。最后，报告讨论了在长寿老人个体层面上评估长寿心理商数（寿商），如何确定一套简便、科学、可靠的关键指标体系，以及测量时要遵循的原则和注意事项。对寿商进行评估和测量将会丰富和完善长寿界定的科学内涵和人文传统，并为延年益寿和健康老龄化的目标提供可参考的量化指标和实现途径。

　　报告题目：青少年自我控制与父母教养方式的关系研究

　　报告摘要：

　　与自我控制相关的领域几乎囊括了人类行为的方方面面，对于处于特定发展阶段的青少年来说，自我控制缺陷会导致很多问题行为，例如物质滥用及暴力行为、攻击行为等。除了这些不良行为，自我控制和学业成就存在高度相关。可见，研究自我控制是解决当前青少年发展问题的关键环节。以往研究表明，应该从冲动系统和控制系统两个方面来评估自我控制。因此，我们在国外已有研究的基础上，以分层整群抽样的方式在六个省份的小学、中学、大学选取了5400多名学生进行问卷调查，进而修订适合从冲动系统和控制系统两方面评估我国青少年自我控制的量表；并通过进一步分析年龄、性别等青少年自身特征以及亲子关系、家庭经济状况、父母文化程度等家庭因素对青少年自我控制的影响，以描述我国青少年自我控制双系统的发展现状；最后，从男/女生两方面分析父/母亲教养方式对青少年自我控制的影响。

　　报告题目：Is there really impairment in patients with schizohrenia to remember for the future actions?

　　Evidence from a large cohort of first-episode schizophrenia

　　报告摘要： 

　　Backgrounds: Prospective memory (PM), the ability to remember to carry out intended action in the future, is a complex cognitive function. Empirical evidence suggests that PM deficits exist in chronic schizophrenia. However, previous PM studies in first-episode schizophrenia showed inconsistent results as to whether PM deficits exist independently from other neuropsychological deficits, and were limited to small inpatient samples. We aimed to clarify the nature and extent of PM deficits, using a large first-episode sample.

　　Methods: Participants were 91 clinically stable outpatients with first-episode schizophrenia and 83 healthy individuals. PM was assessed by both the subjective self-reported checklist and a laboratory-based task capturing time-, event-, and activity-based PM. A set of battery assessing verbal, visuo-spatial, and working memory, and executive functions was also administered to all the participants. Analysis of covariance (ANCOVA) was conducted to examine group difference in PM and to control from other neuropsychological functions. Stepwise linear regression was used to identify neuropsychological functions that predict PM performance in first-episode patients.

　　Results: Patients with first-episode schizophrenia were impaired in both time- and event-based PM but not activity-based PM, after controlling for IQ and other neuropsychological deficits. Regression modeling suggested that cognitive flexibility predicts time- and event-based PM; working memory predicts event-based PM; whereas age predicts activity-based PM.

　　Conclusion: Our results convincingly suggest that time- and event-based PM deficits in first-episode schizophrenia are severe and not attributable to other neuropsychological deficits. PM, as a primary deficit, may constitute a neuropsychological marker of schizophrenia.
