Average-KR schedule benefits generalized motor program learning

The main purpose of this study was to examine the effects of average Knowledge of Results (KR) on generalized motor program learning and parameter learning. Two groups of participants (n = 15 per group) performed 80 acquisition trials of sequential timing tasks. All participants were asked to depress sequentially four keys (2, 4, 8, and 6) on the numeric pad portion of the computer keyboard with the index finger of the right hand. The author presented average feedback on timing errors based on 5-trial blocks and compared this feedback schedule with every-trial feedback. Analysis of the delayed no-feedback retention test indicated a strong advantage for the average KR compared with the every-trial condition in both generalized motor program learning and parameter learning. The current results suggest that the average KR schedule may have positive effects on generalized motor program learning and parameter learning.     

青少年期母子性格与家庭亲密度的关系:性格喜好的作用

研究旨在考察性格喜好与母子性格、家庭成员亲密度的关系以及性格喜好在其他两个变量之间的中介作用。成都市632对初高中学生及其母亲分别自评并填写了艾森克人格问卷,同时评价喜欢对方性格的程度。另外,青少年还报告了与家庭成员的亲密程度。通过相关分析、多元方差分析、层级回归分析以及结构方程模型建模,结果发现：性格喜好与母亲性格、青少年性格均有显著关系,青少年对母亲的性格喜好程度与家庭成员间的亲密感有显著正相关。青少年性格和青少年对母亲的性格喜好程度能直接预测家庭成员亲密度,同时青少年和母亲的性格还通过青少年对母亲的性格喜好程度间接作用于家庭亲密度,提示性格喜好在二者的关系中发挥了重要的中介作用。     

The motivations of adolescents who are addicted to online games: a cognitive perspective

This research explored, from the perspective of cognitive theory, the psychological motivations of Taiwanese adolescents who are addicted to online games. Study 1 focused on the differential motivations between the addicts and nonaddicts. The findings revealed that the addicts exhibited higher intrinsic than extrinsic motivation, whereas the nonaddicts showed an opposite relationship. The intrinsic motivation of the addicts was also higher than the nonaddicts. The results imply that intrinsic motivation plays a crucial role in gaming addiction. Study 2 was conducted to examine whether four factors that moderate the detrimental effect of extrinsic motivators on intrinsic motivation would function as predicted. Results indicated that extrinsic rewards would undermine intrinsic motivation when they were high expectancy, high relevance, tangible, and noncontingent. Thus, players' intrinsic motivation would be higher when extrinsic rewards were low expectancy, low relevance, intangible, and contingent. This article provides insights into the differential motivations of the addicted players and how to employ intrinsic motivators to affect their intrinsic motivation.     

Perceived cultural importance and actual self-importance of values in cultural identification

Cross-cultural psychologists assume that core cultural values define to a large extent what a culture is. Typically, core values are identified through an actual self-importance approach, in which core values are those that members of the culture as a group strongly endorse. In this article, the authors propose a perceived cultural importance approach to identifying core values, in which core values are values that members of the culture as a group generally believe to be important in the culture. In 5 studies, the authors examine the utility of the perceived cultural importance approach. Results consistently showed that, compared with values of high actual self-importance, values of high perceived cultural importance play a more important role in cultural identification. These findings have important implications for conceptualizing and measuring cultures.     

测验情境对错误记忆的影响

本研究采用DRM范式,通过两个实验考察测验情境对错误记忆的影响,结果发现：（1）在两个实验中均产生了错误记忆现象：实验一关键诱饵的错误再认率为M=0．514,SD=0233;实验二关键诱饵的总错误再认率M=0．510,SD=0．215：（2）学习词表的语义关联越大,错误再认率越低：实验一项目语义关联程度主效应显著,F（1,84）=6．145．MSE=0．312．P=0．015;实验二,F（1,84）=5．143,MSE=0．225,P=0．026;（3）关键诱饵的位置造成了不同的情境效应：实验一,关键诱饵出现在第一个位置和第二个位置之间错误再认率差异显著（P=0．024）;实验二,关键诱饵出现第二个位置和第三个位置之间的错误再认率边缘显著（P=0．052）。该研究揭示了情境对错误记忆的影响。     

Relationship between Chinese children's imaginary companions and their understanding of second-order false beliefs and emotions

We investigated relationship between Chinese children's imaginary companions (ICs) and their understanding of second-order false beliefs and emotions in 180 children, aged 5–6 years old. We examined the potential differences in second-order false belief understanding and emotion understanding between children with and without ICs, children with egalitarian IC relationships and hierarchical IC relationships, as well as children with invisible friends and personified objects. The results revealed that children with ICs had better second-order false belief understanding and emotion understanding than children without ICs. Compared with children with hierarchical relationships, children with egalitarian relationships had better second-order false belief understanding. However, children with invisible friends and personified objects did not differ on their understanding of second-order false beliefs and emotions. The results suggest that compared with IC types, IC status and child-IC relationship qualities may be more relevant to children's theory of mind. It will be interesting for the future researchers to investigate the underlying mechanism of the differences between children with egalitarian IC relationships and hierarchical IC relationships.

On the nature of sustainable Economic systems

The theme of the 1982 Tokyo Conference of the Club of Rome is ‘Approaching the 21st Century: Global Problems and Human Choices.’ This is a topic of crucial importance that our generations will have to tackle in all its breadth and depth. Within its context are presented some ideas about the alternatives of the human future.     

The effect of landmarks in human path integration

The effect of landmarks in human path integration was investigated using virtual hallway-mazes. Participants traveled along random 5-segment paths either with or without distinctive landmarks at some segment intersections. They were required to directly return to the origin or to one of the landmark locations from the end of the path. Results showed that knowledge of the return targets prior to the outbound trip significantly reduced RTs to both the origin and the landmarks. Moreover, RTs in the return-to-origin trials were longer with landmarks present than without landmarks. This effect was eliminated when the return target was given prior to the trip. These results suggest that processing of the origin and the landmarks interfere with each other. However this interference is not obligatory and can be eliminated or reduced by prior knowledge about the target. The influences of landmarks on path integration and spatial updating were discussed.     

Nonexpert Evaluations on Architectural Design Creativity Across Cultures

This article examines the relationship between cultural differences and the nonexpert evaluations of architectural design creativity. In study I, Caucasian Americans (N = 126) and East Asians (N = 137), who did not major in architecture and urban design, evaluated the novelty and appropriateness of 5 unusual architectural shapes, selected by 5 experts in the field of architecture. In study II, the 2 cultural groups selected preferred alternatives from 3 pairs of silhouettes of architectural shapes that were distinctive and indistinctive from the adjacent environments. The data were collected by an online survey tool. Multiple analysis of variance (MANOVA) and subsequent t-tests revealed that East Asians awarded lower scores as regards the novelty and appropriateness of unusual, novel architectural forms, and that they accepted unusual and distinctive architectural shapes less than the Caucasian Americans did. These results indicated that cultural differences between these 2 groups affected the nonexpert creativity evaluations, as introduced in previous cross-cultural studies. The East Asians’ creativity evaluations and preference tests were possibly influenced by their perceptions of contextual information and emphasis on the holistic and interdependent relationships amongst environmental elements, whereas the Caucasian Americans’ evaluations were related to their analytic tendency to be aware of focal objects and independent identity.
