Muscular Activation Pattern of Bilateral Extensors Response to Asymmetric Hand Lifting During Trunk Flexion–extension Performance

The authors' purpose was to test the effect of asymmetric hand lifting on muscular activation patterns of 3 bilateral extensors. Eighteen male university students without back pain were volunteered. Each performed flexion–extension randomly with conditions of right lifting, left lifting, and nonlifting. Surface electromyography from bilateral thoracic, lumbar erector spinae, and hamstring was recorded. The cross-correlation and relative intensity in paired muscles of bilateral extensors was calculated in flexion as well as extension period. The results showed that the cross-correlation coefficient was decreased and the phase lag as well as the relative intensity of bilateral extensors was increased significantly in thoracic level. The phase lag as well as the relative intensity of bilateral extensors was increased significantly in lumbar level. It was concluded that asymmetric lifting has a significant effect on muscular activation of bilateral extensors in thorax level, which causes the ipsilateral extensor to activate larger and longer. Asymmetric lifting also has some effect on muscular activation of bilateral extensors in lumbar level but with less extent than in thorax level, which causes contralateral extensor to activate larger and longer. Asymmetric lifting seems to have no significant effect on muscular activation of bilateral hamstring.     

The fate of completed intentions

The goal of this research was to determine whether and how people deactivate prospective memory (PM) intentions after they have been completed. One view proposes that PM intentions can be deactivated after completion, such that they no longer come to mind and interfere with current tasks. Another view is that now irrelevant completed PM intentions exhibit persisting activation, and continue to be retrieved. In Experiment 1, participants were given a PM intention embedded within the ongoing task during Phase 1, after which participants were told either that the PM task had been completed or suspended until later. During Phase 2, participants were instructed to perform only the ongoing task and were periodically prompted to report their thoughts. Critically, the PM targets from Phase 1 reappeared in Phase 2. All of our measures, including thoughts reported about the PM task, supported the existence of persisting activation. In Experiment 2, we varied conditions that were expected to mitigate persisting activation. Despite our best attempts to promote deactivation, we found evidence for the persistence of spontaneous retrieval in all groups after intentions were completed. The theoretical and practical implications of this potential dark side to spontaneous retrieval are discussed.     

What Contributes to College Students’ Cheating? A Study of Individual Factors

To better understand the multiple individual factors that contribute to college cheating, we undertook a multivariate analysis of a national sample of 2,503 college students. Our findings indicated that demographic characteristics (e.g., gender, socioeconomic status, and year in college), character qualities (e.g., lack of self-control, others-oriented life purpose), college experience (e.g., academic preparation, extracurricular activities involvement, and working), and student perceptions and attitudes (e.g., attitude toward academic cheating, perception of faculty’s actions against cheating and cheating environment) are all significantly associated with academic cheating.     

Value From Regulatory Fit

Abstract— Where does value come from? I propose a new answer to this classic question. People experience regulatory fit when the manner of their engagement in an activity sustains their goal orientation or interests regarding that activity. When there is fit, people engage more strongly in what they are doing and "feel right" about it. Fit influences the strength of value experiences—how good or how bad one feels about something—independently of the pleasure and pain experiences that are associated with outcomes. It uniquely contributes to people's experience of the value of things. Fit is shown to influence judgments and decision making, attitude and behavior change, and task performance.     

大学生上网行为、态度和人格特征的研究

本研究使用自编大学生上网成瘾诊断问卷、自编上网行为和态度问卷以及三个人格量表,对上海市6所高校370名大学生的上网情况进行了调查。结果表明：(1)上网成瘾的大学生在上网的行为和态度上明显不同于非成瘾的大学生,他们表现出高开放性、社交性、胜任能力和匿名性,并且更认可网络交流的便利性。(2)上网成瘾的大学生比非成瘾的大学生明显表现出孤独、抑郁和焦虑的人格特质。(3)逐步回归分析的结果表明,“社交性”、“交流便利”、“焦虑量表分数”、“开放性”、“胜任能力”对大学生陷人网络的程度有显著的预测作用。     

印象整饰与内隐态度效应

运用内隐联想测验对不同印象整饰水平个体的内隐态度进行了研究。结果表明：不同自我监控者的内隐性态度是存在的,高自我监控者的内隐态度和外显态度存在分离。研究对“印象整饰对强迫服从后态度改变的影响”的结果做出解释：自我监控者强迫服从后的态度中庸是其关注自身的公众形象而有意压抑和控制其内隐性的评价造成的。     

女护士生性教育现状及需求的调查分析

本研究以大连某卫校女护士生为研究对象,采用自编式问卷对女护士生的性教育现状及需求进行了调查分析.结果表明:卫校女生在性知识、性态度、性行为方面发展的主流是好的、健康的,但也有少数女护士生对自身正常的性生理、性心理现象不了解而产生心理困惑和压力,女护士生渴望从学校得到正规的性教育.为了使女护士生身心得到健康发展,学校必须开展以性道德教育为核心的正规的性教育.

青少年对广告的态度及影响因素

通过对北京城八区11所中学的730个有效样本的研究分析,作者发现,北京青少年对广告的总体态度比较消极, 40.2%的青少年表示不喜欢广告, 27.9%中立,只有31.9%喜欢广告;此外,61.6%的青少年表示不信赖广告,24%中立,仅14.5%的青少年表示信赖广告。在对广告信念的因子分析中,青少年对广告“决策信息”功能表示基本肯定;对广告的“娱乐”、“购买体验”和“个人伤害”结果表示基本否定。此外,人口统计变量与广告总体态度以及各个因子之间有一定的关系。因此,要改变青少年对广告的消极态度,企业营销者需要从产品质量、广告表现形式、广告诉求内容等多个方面加以改善和提高。     

Semantic computations of truth based on associations already learned

This article sets forth a detailed theoretical proposal of how the truth of ordinary empirical statements, often atomic in form, is computed. The method of computation draws on psychological concepts such as those of associative networks and spreading activation, rather that the concepts of philosophical or logical theories of truth. Axioms for a restricted class of cases are given, as well as some detailed examples.
