这篇论文调查了短期目标和长期目标对投篮成绩、努力程度和状态焦虑的影响．８７名被试被随机分配到以下一个组中：（１）短期目标组,（２）长期目标组,（３）短期和长期目标结合组,（４）“尽力做好”组。实验时间为７周。研究结果显示：（１）结合目标组、短期目标组和长期目标组的投篮成绩显著优于“尽力做好”组;（２）结合目标组的投篮成绩提高幅度最大,其次是短期目标组和长期目标组,最后是“尽力做好”组,（３）结合目标组、短期目标组和长期目标组的投篮成绩随练习次数的增加而显著提高,（４）努力程度是结合目标组和短期目标组投篮成绩提高的调节变量。     

Motivational-behavioral correlates of goal orientation and perceived motivational climate in physical education contexts.

The purpose of this study was to investigate how goal orientation (task and ego) and perceived motivational climate (mastery and performance) related to intrinsic motivation, self-esteem, adherence, and evaluated skill within Korean physical education contexts, 218 men attending physical education classes completed the Korean versions of the Perception of Success Questionnaire and the Perceived Motivational Climate in Sport Questionnaire, including a battery of motivational and behavioral assessments. Confirmatory factor analyses suggested that over-all fit for the modified versions of the questionnaires were reasonably acceptable. The results of canonical correlation analyses indicated that the task goal orientation was positively associated with intrinsic motivation and self-esteem, while the climate of perceived mastery was positively related to intrinsic motivation, adherence, and evaluated skill. These results were discussed within the frame of goal perspective theory in physical education contexts.     

人类视觉系统获取颜色恒常性的认知操作特性

以光度测量为基础,采用心理物理学方法,探讨人类视觉系统获取颜色常性的认知特性。共进行了两个实验。实验一,探讨颜色对比对获取颜色常性的认知操作过程的作用。结果发现,视觉系统可根据已适应了的对比参照作用,而校正（或补偿）由于外界照明变化而引起的物理色度变化。实验二,探讨视觉经验对人类视觉系统获取颜色常性的作用。结果发现,颜色常性不仅是一种视觉低层次、自动完成的补偿,而且涉及高层次的意识活动。     

智力落后的实验研究及普查结果的分析

智力落后,就其本身来说,不是一种综合症,而是许多不同病因导致中枢神经系统受到损伤,表现为大脑功能发生障碍的一种症状。它发生于发育阶段,是以智力低下和社会顺应不良为特征的。 智力落后的患病率在全世界范围都很高,虽然由于社会要求的标准及年龄取样不同而不完全一致。智力落后是当今社会面临的最重要的社会和医学问题之一,许多国家

The Manifestation Range of Innately Good Knowledge and Ability,and the Danger of Separation: On Zhuzi’s Question about Understanding Words

Zhuzi (Zhu Xi), Zhang Nanxuan and Lü Donglai continued a discussion begun by Hu Wufeng and his disciples on the subject of “knowing the form of benevolence,” and “seeking for a true mind in an absent one.” One result of their discussion was to make people realize that innately good knowledge and ability are not only manifested in loving one’s parents and respecting one’s elders, but also in the simple acts of drinking when thirsty and eating when hungry. This generated the idea of “manifestation range of innately good knowledge and ability.” However, another conclusion of this discussion claimed that if the desire to drink and eat or the king of Qi’s grudging an ox are included in this range, there would be a danger of viewing innately good knowledge and ability merely as inborn human nature or instinct. This discussion reveals an unsteady relationship between innately good knowledge and ability and the feeling of commiseration, which are sometimes united and sometimes separate.     

Simplicity and generalization: Short-cutting abstraction in children's object categorizations

Development in any domain is often characterized by increasingly abstract representations. Recent evidence in the domain of shape recognition provides one example; between 18 and 24 months children appear to build increasingly abstract representations of object shape [Smith, L. B. (2003). Learning to recognize objects. Psychological Science, 14, 244-250]. Abstraction is in part simplification because it requires the removal of irrelevant information. At the same time, part of generalization is ignoring irrelevant differences. The resulting prediction is this: simplification may enable generalization. Four experiments asked whether simple training instances could shortcut the process of abstraction and directly promote appropriate generalization. Toddlers were taught novel object categories with either simple or complex training exemplars. We found that children who learned with simple objects were able to generalize according to shape similarity, typically relevant for early object categories, better than those who learned with complex objects. Abstraction is the product of learning; using simplified - already abstracted instances - can short-cut that learning, leading to robust generalization.     

Finding groups using model-based cluster analysis: heterogeneous emotional self-regulatory processes and heavy alcohol use risk

Model-based cluster analysis is a new clustering procedure to investigate population heterogeneity utilizing finite mixture multivariate normal densities. It is an inferentially based, statistically principled procedure that allows comparison of nonnested models using the Bayesian information criterion to compare multiple models and identify the optimum number of clusters. The current study clustered 36 young men and women on the basis of their baseline heart rate and heart rate variability (HRV), chronic alcohol use, and reasons for drinking. Two cluster groups were identified and labeled the high alcohol risk and normative groups. Compared to the normative group, individuals in the high alcohol risk group had higher levels of alcohol use and more strongly endorsed disinhibition and suppression reasons for use. The high alcohol risk group showed significant HRV changes in response to positive and negative emotional and appetitive picture cues, compared to neutral cues. In contrast, the normative group showed a significant HRV change only to negative cues. Findings suggest that individuals with autonomic self-regulatory difficulties may be more susceptible to heavy alcohol use and use of alcohol for emotional regulation.     

Do brief personalized feedback interventions work for mandated students or is it just getting caught that works?

Studies evaluating the efficacy of brief interventions with mandated college students have reported declines in drinking from baseline to short-term follow-up regardless of intervention condition. A key question is whether these observed changes are due to the intervention or to the incident and/or reprimand. This study evaluates a brief personalized feedback intervention (PFI) for students (N = 230) who were referred to a student assistance program because of infractions of university rules regarding substance use to determine whether observed changes in substance use are attributable to the intervention. Half the students received immediate feedback (at baseline and after the 2-month follow-up), and half received delayed feedback (only after the 2-month follow-up). Students in both conditions generally reduced their drinking and alcohol-related problems from baseline to the 2-month follow-up and from the 2-month to the 7-month follow-up; however, there were no significant between-group differences at either follow-up. Therefore, it appears that the incident and/or reprimand are important instigators of mandated student change and that written PFIs do not enhance these effects on a short-term basis but may on a longer term basis.
