n-back任务下视觉工作记忆负荷研究

实验采用n-back范式,考察了视觉工作记忆负荷与反应时、辨别力和主观评价的关系,以及空间位置记忆负荷与图形记忆负荷的差异。结果发现,随着记忆负荷的增大,反应时延长,辨别力降低,主观负荷提高。视觉图形记忆任务的负荷水平高于视觉空间位置记忆任务的负荷水平;同时也为视觉图形记忆和视觉空间记忆具有不同的加工过程提供了证据。

本文介绍数字式肌电显示仪。由微电极检测得到的肌电信号经过放大器之后被本仪器以数字形式显示出来,由于其具有对输出量的保持以及提供不同的展示肌电值的时间间隔的功能,它可以用于估计和分析人体的紧张程度。本仪器已用于国家射击队的心理训练。     

Preschool children's understanding of the coordinators “and” and “or”

The development of the understanding of the words and and or was studied. Children in the age interval 2:0–7:6 received two tests of word understanding, varying in the degree to which the context of the test items contributed in determining the meaning of the connectives, and one test of spontaneous usage. The results from the tests of word understanding showed that the context variable facilitated small children's responding, and that most reponses were correct at the age of four and beyond. The results from the production test indicated that and was used to express enummerations and or to express alternatives. The difference between the linguistic and the logical meaning of the connectives was discussed.     

EFFECTS OF INTERSTIMULUS INTERVAL AND PREDICTABILITY OF EVENT STRUCTURE ON SERIAL REACTION TIME

A mean interstimulus interval (ISI) of 10 sec. resulted in significantly-shorter RTs to a single light stimulus than a 30 sec. average ISI. During a second workperiod the groups performing under each of the two ISI conditions were divided into four subgroups given 0, 25, 50 or 75% interspersion of an additional stimulus (sound). With short ISIs the condition of maximum predictability of event structure (light stimulus only) gave the shortest average RTs. With lessened predictability (increased proportion of the sound stimulus) there was a slight monotonous increase in RT. With long ISIs the same relationship was curvilinear, i.e. 25% interspersion of sound stimulus was most effective in preserving vigilance.     

Chinese undergraduates' preferences for altruistic traits in mate selection and personal advertisement: Evidence from Q‐sort technique

Human's preferences for altruistic mates have been confirmed by many researchers. Under the deep influence of Confucianism that authorised more parental control over offspring's mate selection, Chinese people's mating strategies and mate preferences may be different from what the evolutionary psychologists have suggested. This study used the Q‐sort technique to assess the roles of altruistic traits in mate selection and personal advertisement. A total of 200 university students participated in the Q‐sort procedures and were asked to sort 50 traits (among which altruistic traits were mixed) according to their importance when choosing (or advertising to) a long‐term (LT) or a short‐term (ST) mate. Our findings were quite different from prior studies. When Chinese participants chose a mate or advertised themselves to a potential mate, kin altruism was considered to be the most important trait; altruistic traits were more preferred by males than by females and females tended to advertise themselves as more altruistic; preferences for altruistic traits showed no difference between LT and ST mate selections (or between personal advertisement to a LT and a ST mate).     

中国性伦理研究发展概况及分析

中国性伦理研究在50年代、80年代、21世纪初期经历了三次高潮,表现出以婚姻家庭研究为主,以道德实践的要求为动力的基本特征.中国性伦理研究的主要内容包括三个方面,即马克思恩格斯对性道德问题的基本观点.社会主义爱情、婚姻及家庭道德以及当代中国性伦理面临的挑战及发展.现阶段,应当深入挖掘马克思主义性伦理思想的基本原理,加强对性权利的研究,并在此基础上发展马克思主义性伦理理论.     

语言理解中语义整合的神经机制

语义整合是语言阅读理解中非常重要的环节。随着认知神经科学技术的广泛应用,当前关于语义整合的研究取得了长足进步,各种模型层出不穷。但是不同模型对于语义整合的功能定位及其内在机制却存在较大的争议。本文首先介绍当前关于语义整合的主要模型,然后对当前不同理论模型之间关于语义整合的界定,以及语义整合的功能定位是在额下回还是颞叶的争论进行了分析。我们认为,关于语义整合的实质、语义整合的功能网络将是未来研究的主要方向,相关的研究对于语言理解理论的发展将具有重要的启示。     

变革型领导与员工心理健康:工作情感的中介作用

通过对550位员工的问卷调查,探究员工工作情感在变革型领导行为与员工心理健康间的中介作用。结构方程模型结果表明:(1)变革型领导行为与员工心理健康得分呈显著负相关;与愉快情感呈显著正相关,与不愉快情感呈显著负相关;(2)高激活愉快情感与心理健康得分呈显著负相关,高、低激活不愉快情感与之呈显著正相关,且中介变革型领导行为与心理健康间关系。变革型领导会积极影响下属的工作情感,进而对其心理健康产生积极影响。     

应对风格与焦虑水平、任务完成效率关系的实验研究

通过实验的方法来考察应对风格、应激情境对焦虑水平、任务完成效率的影响。结果表明：应对风格和应激情境对焦虑水平和任务完成效率影响的主效应和交互效应都非常显著。在实验中,控制型应对风格的个体总体上表现出较低的焦虑水平和较高的任务完成效率。在低任务难度情境下,灵活应对风格和控制型应对风格的个体比非控制型应对风格和反常应对风格的个体表现出更低的焦虑水平和更高的任务完成效率,而且不同应对风格被试在焦虑水平和获胜率上的差异显著。
