Fitts’ law holds for pointing movements under conditions of restricted visual feedback

Fitts’ law robustly predicts the time required to move rapidly to a target. However, it is unclear whether Fitts’ law holds for visually guided actions under visually restricted conditions. We tested whether Fitts’ law applies under various conditions of visual restriction and compared pointing movements in each condition. Ten healthy participants performed four pointing movement tasks under different visual feedback conditions, including full-vision (FV), no-hand-movement (NM), no-target-location (NT), and no-vision (NV) feedback conditions. The movement times (MTs) for each task exhibited highly linear relationships with the index of difficulty (r² > .96). These findings suggest that pointing movements follow Fitts’ law even when visual feedback is restricted or absent. However, the MTs and accuracy of pointing movements decreased for difficult tasks involving visual restriction.     

文化生活脚本理论及其研究进展

为了解释人对于生活事件的回忆出现的记忆隆起现象,出现了文化生活脚本理论。文化生活脚本是文化上共享、关于重要生活事件发生时间及顺序的知识。它是规范事件的图式,可以用来检索和叙述个人过去经历的过程。文章综述了文化脚本的研究及其进展,并对进一步的研究提出了设想。     

"嫁主里面的人"——乡村基督徒姻亲结合的宗教社会学观

乡村社会出现越来越多基督徒与基督徒的姻亲结合,我们通过基督教经典<圣经>投射的神与基督徒、基督徒家庭结构、婚姻行为、婚姻观念的统计,结合婚礼发挥的姻亲结合认同、基督徒群体团结的功能分析,探析基督徒姻亲结合表达的宗教及社会需求所在:乡村基督徒姻亲结合,是信徒构建神圣与世俗秩序的宗教需求,同时,宗教关系的血亲化、家族化,满足了作为基督徒的村民对熟人社会再造的社会需求.     

人类道德的历史形态论析

马克思主义的社会形态理论是理解道德历史形态的钥匙。五形态论和三形态论都是唯物史观分析人类社会发展史得出的正确结论。相应地有道德发展三形态论和五形态论,三形态论更符合道德的内在精神。以此为理论基础进行分析,现实社会主义道德处于物的依赖关系为基础的人的独立性的单子式的道德发展阶段,虽然其起点比当时资本主义还低,但社会主义道德以其科学的指导思想、先进的政治制度和高尚的价值追求为落后国家摆脱整体性道德、超越单子式道德、建立和发展人的自由全面发展的和谐型道德开辟了广阔的前景。     

青少年网络成瘾人格特征研究

本研究采用问卷调查法,对某初级中学363名初中生的网络成瘾状况与人格特征进行研究。结论表明:初中生网络成瘾检出率为5.79%;初中生在网络成瘾存在性别差异,男生比女生更易成瘾。网络成瘾学生与非成瘾学生在《卡特尔十四种人格因素问题》中的忧虑性、自律性、适应性与焦虑性、孤独倾向、身体症状和冲动倾向等因子上差异显著。与非成瘾学生相比,成瘾学生的自制能力较差,成瘾学生可能更经常体验到孤独、焦虑和不满,并且在生活中较容易出现适应不良现象。     

Impact of signals and experience on trust and trusting behavior

Trust is an essential factor that drives virtual interaction and transactions on the Internet. Researchers have investigated the trust development process, and identified several important factors that form the basis for trust. This research combines the signal perspective and trust theory to examine the impact of market signals and past experience on trust formation and trusting behavior. Three market signals, including brand image, Web-site investment, and privacy policies, are identified and empirically tested to determine their impact on consumer trust. Based on 322 active Web users, the quantitative results suggest that brand image, Web-site investment, privacy policies, and past experience all positively impact trust formation. Furthermore, trust shows a positive effect on Web-site stickiness. Both theoretical and practical implications of the results are also offered.     

基于行为事件的履历资料评估

行为事件的履历资料评估能有效克服传统履历数据构思效度弱、情景限制多等问题。本研究结合某通信企业招聘工作,选取250名应聘者数据,结合关键事件法,通过对履历事件的行为锚定来评估应聘者的胜任特征。研究在多重比较行为履历资料、履历表数据、认知能力等多个指标组合对录用结果预测的回归模型基础上,检验新增指标的预测效度。结果表明,行为事件的履历资料评估具有效标关联效度,与其他工具组合使用时具有增量效度。     

Psychometric analysis of the short-form UCLA Loneliness Scale (ULS-8) in Taiwanese undergraduate students

The main purpose of this study was to validate the short-form of the UCLA Loneliness Scale (ULS-8; Hays & DiMatteo, 1987) in Taiwanese undergraduate students. A total of 130 undergraduate students participated in this study. Participants completed the ULS-8 in addition to measures of life satisfaction, social support, and adult attachment style. Result of confirmatory factor analysis supported the one-factor model of the ULS-8 with adequate values of various fit indices, revealing that the 8 items of the scale were homogeneous for measuring loneliness. In addition, the ULS-8 had a negative relationship with life satisfaction, and social support; and a positive one with anxiety and avoidant attachment tendency. All the findings showed that the ULS-8 was an adequate short-form measure of loneliness.     

论智力对专长获得的非决定性

个体获得某领域杰出能力(专长)并非由其智力简单决定.一方面,智力测验无法预测个体未来成就以及"SOC、智力、专长三角关系理论"的提出,似乎表明智力与专长获得无关;另一方面,"特质联合体中介理论"和"模块能力与综合能力中介理论"则说明智力与专长间存在复杂中介机制.专长的获得是多种因素综合作用的结果,在个体一生发展的历程中,智力对专长获得并不具有显著的决定性.
