视觉工作记忆中特征绑定关系的记忆机制

弱客体理论认为, 视觉工作记忆系统是由众多特征存储的子系统组成, 不同纬度的特征独立存储在相应的有限容量的子系统中, 相互之间不会竞争记忆资源。而对于特征之间绑定关系的记忆存在不同的观点。一种观点认为绑定关系的记忆需要注意维持, 因此绑定关系的记忆会占用到特征记忆的资源; 另一种观点认为绑定关系的记忆是自动发生的, 不需要注意的维持。本实验的目的是探究特征绑定关系的记忆是否是自动发生的。在实验中, 我们设计了两种任务, 一种任务是只记忆颜色, 另一种任务是记忆颜色跟位置及其之间的绑定关系, 并测试分析视觉工作记忆相关的ERP成分CDA。结果发现两种任务条件下的CDA波幅之间没有显著差异, 说明视觉工作记忆中的特征绑定是自动发生的。     

Dispositional and situational goal orientations as discriminators among recreational and competitive league athletes.

The present study examined the relationship between individual goal orientation, motivational team climate, perceived sport competence, and league structure among 216 youth soccer players. It was predicted that competitive league teams would report higher ego-involvement and performance-oriented team climate and lower sport competence than recreational teams. Discriminant analyses indicated that only the mastery-oriented team climate variable differentiated competitive and recreational teams. Athletes who participated in recreational teams reported a greater degree of mastery-oriented climate than competitive league players. The results suggest that athletes' perceptions of situational rather than dispositional aspects of achievement goals are more highly affected by the playing structure present in youth sport teams. The possible psychological benefits derived from the development of a mastery-oriented team climate in sports are discussed.     

Does Parent-Child Interaction Therapy Reduce Maternal Stress,Anxiety, and Depression Among Mothers of Children with Autism Spectrum Disorder?

Maternal stress, anxiety, and depression are associated with ineffective parenting strategies for families of children with Autism Spectrum Disorders (ASD). We present the use of Parent-Child Interaction Therapy (PCIT) with three mother-child dyads to reduce maternal stress, anxiety, and depression and child disruptive behavior in children with ASD. Results included increases in positive parenting skills, and decreases in maternal anxiety, depression, and stress, as well as child behavior problems. PCIT is a promising alternative to more intensive and costly interventions, both at reducing disruptive behaviors and improving maternal health. Implications of PCIT for dyads affected by ASD are discussed.     

走神对中文阅读绩效的影响

选取36名大学生被试,采用探针检测的方法和逐句阅读范式,考察被试阅读中文材料时走神对阅读正确率和阅读时间的影响。结果发现:(1)中文阅读中出现走神的时间占34.80%;(2)走神会影响阅读理解,降低阅读理解正确率;(3)走神会导致阅读时间变慢。这些发现均证实走神对中文阅读绩效有影响,降低阅读理解正确率和减缓阅读时间。     

Contributions of striatal subregions to place and response learning

The involvement of different subregions of the striatum in place and response learning was examined using a T-maze. Rats were given NMDA lesions of the dorsolateral striatum (DLS), anterior dorsomedial striatum (ADMS), posterior dorsomedial striatum (PDMS), or sham surgery. They were then trained to retrieve food from the west arm of the maze, starting from the south arm, by turning left at the choice point. After 7 d of training, with four trials a day, a probe test was given in which the starting arm is inserted as the north arm, at the opposite side of the maze. A left turn would indicate a "response" strategy; a right turn, a "place" strategy. The rats were then trained for 7 more days, followed by a second probe test. Unlike rats in the other groups, most of the rats in the PDMS group turned left, using the response strategy on both probe tests. These results suggest that the PDMS plays a role in spatially guided behavior.

Burger or yogurt? Indulgent consumption in impression management contexts

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.     

孤独症碎镜理论述评

孤独症是泛指一大类在社会交往、沟通方面存在功能缺陷的疾病, 至今病因尚未阐明。“碎镜理论”作为孤独症研究领域的新兴理论, 在神经—认知层面较先前理论更为全面地解释了孤独症的各种临床行为表现, 并为这些异常行为间的相互关系提供了一种统一性的研究视角。文章首先对镜像神经元的发现进行了简介, 在此基础上对碎镜理论的由来及其与孤独症相关功能(包括动作识别与模仿、心理理论、共情以及语言理解)缺陷的关系进行了综述, 最后通过区分主动模仿和自动模仿, 就镜像神经元系统及其调控系统与孤独症关系中存在的问题进行了反思与展望。     

十斋日补说

对十斋日的来源及地藏菩萨十斋日,法国学者苏远鸣与中国学者张总、王承文等已进行了卓有成效的研究,但他们于佛教对十斋日的具体接受过程还缺乏深入的考察。本文就此提出补说。认为:佛教徒对十斋日的态度经过了由拒斥到吸收的过程;在统治者推行十斋日,以及民众修习实践的压力下,十斋日在盛唐、至少是中唐时期已进入佛教经典,至少在中唐时期已被信奉者归之于佛教;佛教徒对十斋日的改造使其反而取代了道教十斋日,在民众信仰生活中占据了主导地位;而目前将敦煌遗书中的十斋日统称为《地藏菩萨十斋日》是不恰当的,后者乃《地藏菩萨本愿经》吸收十斋日所产生的结果,而它的称谓,似也应以写本中用得较多的《地藏菩萨经十斋日》为准。
