旧证据问题：一种动态的消解方案

旧证据问题是指贝叶斯确证理论在讨论旧证据确证新理论（假说）的问题上将出现不合理的结果,它的消解是贝叶斯确证理论辩护的一个非常重要的环节。本文倡导一种基于Levi理论的动态方案来消解这一问题。在这种方案下,知识汇集的动态性使得旧证据在新理论引入前后的置信概率可能是不相同的,在此基础上我们证明,经新理论扩充后而得到的知识汇集无论是一致扩充还是不一致扩充,均存在一个旧证据E,它对该新理论具有确证作用。     

Parental, peer, and teacher influences on the social behavior of Hong Kong Chinese adolescents

Intensive interviews and self-report questionnaires were used to investigate parental, peer, and teacher influences on the prosocial and antisocial behaviors of Hong Kong Chinese adolescents. Students came from 5 academically different high schools. Results indicated that perceived parental influence was positively associated with frequency of prosocial behavior and negatively associated with frequency of delinquent behavior. Students with good relationships with their parents and peers showed lower frequencies of antisocial behaviors than did students with bad relationships. Adolescents in different identity statuses (achievement, moratorium, foreclosure, diffusion; E. H. Erikson, 1968) showed different patterns of prosocial and antisocial behaviors. For example, adolescents in the identity achievement group exhibited high frequencies of prosocial behaviors and low frequencies of antisocial behaviors, but those in the identity moratorium group exhibited quite high frequencies of both prosocial and antisocial behaviors.     

Modulation of recognition and temporal order memory retrieval by dopamine D1 receptor in rats

The present study examines the effects of SKF 81297, a selective D1 agonist, on information retrieval in recognition and temporal order memory for objects, using three different tasks. Separate groups of rats were trained in each task and then given an intraperitoneal injection of saline or the D1 agonist (0.03, 0.3 mg/kg), before the memory testing trial in an object recognition, object location, and object temporal order memory tasks. We show that SKF 81297, at high dose (0.3 mg/kg), facilitates information retrieval after a long delay (4 h) in the three memory tasks whereas both high and low doses of D1 agonist impair recognition memory after a short delay (15 min). These results indicate a significant role of dopamine D1 receptors in recognition memory for both familiarity and place of objects in addition to object temporal order memory.     

大学生亲社会倾向、亲社会推理以及它们的相关模式

采用《亲社会倾向测量》和《亲社会推理客观测量》研究了17至20岁大学生的六类亲社会倾向和亲社会推理的状况。发现大学生将利他的亲社会倾向列为六类倾向中的首位,接下来依次是紧急的、情绪性的、依从的、匿名的和公开的亲社会倾向;在亲社会推理五种类型中大学生选择比率最高的是内化价值定向的推理,接下来依次是刻板定向、需要定向和享乐主义定向的推理,所占比率最低的是赞扬定向的推理;六类亲社会倾向与亲社会推理之间具有特定的棚关模式．利他的和匿名的亲社会倾向与内化价值定向和刻板定向的推理正相关、与享乐主义定向及赞扬定向的推理负相关,公开的亲社会倾向与赞扬定向的推理正相关、与需要定向的推理负相关。跨文化比较证实,中美大学生的上述三个方面表现出一定的差异。     

Chinese immigrant mothers of adolescents: self-perceptions of acculturation effects on parenting

Immigrant families in the United States experience many adjustments, including the challenge of parenting in a new context. The relationship between self-perceptions of parenting behavior and mothers' perceived acculturation levels for themselves and their children was examined in 95 Chinese immigrant mothers. Data showed that mothers perceived their children as more acculturated than themselves, mothers reported a great need to learn more about how their children are growing up today, a larger perceived acculturation gap was associated with more parenting difficulties, and several factors contributed to perceptions of a more favorable parenting experience. Culturally responsive methodologies used in the translation and administration of measures, and specific modifications made to develop the Chinese version of the Parent Success Indicator, are discussed.     

中国人眼光谱相对视亮度函数的研究——Ⅳ.亮度级对光谱相对视亮度的影响

本研究主要采用闪烁光度法得到四个亮度级上的相对视亮度曲线。以此为基准进而又作出了相应亮度级上最小可觉明度差别阈限曲线。所得结果表明随亮度级增高,光谱相对视亮度发生变化:在可见光谱中段,保持不变,两端降低。     

Altruistic Orientation in Children: Construction and Validation of the Child Altruism Inventory

The Child Altruism Inventory (CAI) consisted of 24 yes-or-no items which measured the altruistic orientation of children. The sample included 1095 Grades 2 to 6 Chinese children in Hong Kong, The test-retest and internal consistency reliabilities of the CAI were in the 0.70s. The correlations of the CAI score with the intelligence and self-esteem scores were significantly positive, while the correlations of the CAI score with the psychoticism and neuroticism scores were significantly negative. Children in classes of positive and negative social environment rated high and low on the CAI respectively. The relations of the CAI score with self-report prosocial and delinquent behavioural indices were also positive and negative respectively. The psychometric properties of the CAI are regarded as quite good.     

Role adjustment as the unit of analysis for researching child development during the transition to school

While child development is well-recognized as a complex process which could hardly be decomposed into separate lines or domains in contemporary psychological theories, the decomposition approach is widely used in empirical studies. Based on the cultural-historical theory, this study argues for adopting the unit of analysis as a way to bridge this gap, and finds “role adjustment” as a suitable unit to analyse child development during the transition to school. The case of a 5-year-old second-generation Chinese Australian child's transition to school (with a total of 34 h of observation and 5 h of interview) is presented to verify its feasibility and to illustrate how it could be achieved in a research practice. The case study demonstrates that a child's role adjustment is in essence a process of transforming his/her role system, during which his/her major roles, the relation of the major roles, as well as his/her role-taking patterns change as a whole, and by tracing a child's role adjustment trajectory, how the child is learning and developing, what difficulties he/she encounter, and why these difficulties appear become clear.     

社会价值取向与损失情境对不同时间压力下双人社会困境中合作行为的影响

为揭示双人社会困境中合作行为的影响因素,选取四种不同类型的双人社会困境,采用实验法考察社会价值取向与损失情境对不同时间压力下合作行为的影响。结果显示,亲社会个体的合作率显著高于亲自我个体的合作率,收益情境下的合作率显著高于损失情境下的合作率,在社会困境中双方冲突程度越大合作率越低;此外,高时间压力提升了亲自我个体在囚徒困境以及收益情境下信任困境中的合作率,同时降低了亲自我个体在损失情境下最大差异困境中的合作率。结果表明,社会价值取向、收益损失情境以及困境冲突程度均对合作行为的发生具有影响作用,而时间压力对合作行为的作用也同样受到三者的影响。这些发现能够为合作行为自动性的理论分歧提供新的证据。
