Depletion from Self‐Regulation: A Resource‐based Account of the Effect of Value Incongruence

Value incongruence between employees and organizations has been identified as a negative work condition. An attitude‐based account suggests that value incongruence gives rise to negative attitudes toward organizations and thus causes low performance. To complement this mechanism, we propose a resource‐based account based on ego‐depletion theory, which suggests that value incongruence consumes an individual's regulatory resources and leads to low work performance. In support of this view, results from 2 survey studies and a vignette experiment reveal that value incongruence is positively associated with ego depletion, which in turn is negatively related to work performance. The mediation effect of ego depletion is independent of the attitude‐based mechanism as represented by job satisfaction and affective commitment. Consistent with the affective consistency perspective, the relationship between value incongruence and ego depletion is stronger among employees high in positive affectivity and weaker among employees high in negative affectivity. The corresponding moderated mediation analysis shows that the indirect effects of value incongruence on work performance through ego depletion vary as a function of positive and negative affectivity. This investigation unravels the self‐regulatory consequence of value incongruence and shows that the resource‐based mechanism of value incongruence operates differentially as a function of dispositional affectivity.     

经典氧债学说研究进展

Hill和 Margaria等依据乳酸代谢动力学特征对氧债现象所作的理论解释曾统治对该问题的研究长达半个世纪 ,然而 ,采用新的测试技术研究发现 ,经典氧债学说至少在以下三个方面与当代生理学研究有明显的冲突 ,即氧亏与氧债的关系、乳酸与氧耗的一致性和乳酸转变为肌糖。本文就上述研究进行简要回顾。     

关于儿童内包量概念发展的研究

自从Piaget等人提出对时概念的守恒性进行研究以来,对儿童比例概念形成的研究就成了儿童概念形成研究的一个热点,并积累了比较丰富的实验成果,提出了许多新的研究课题。近来,国外一些研究者又提出了对内包量概念进行研究。本文试就国内外关于内包量概念研究的主要取向、研究的一些新进展、内包量概念形成的实质等作一综合的介绍。     

Information transmission with a multifinger tactual display

In this work, the tactual information transmission capabilities of a tactual display designed to provide stimulation along a continuum from kinesthetic movements to cutaneous vibrations are assessed. The display is capable of delivering arbitrary waveforms to three digits (thumb, index, and middle finger) within an amplitude range from absolute detection threshold to about 50 dB sensation level and a frequency range from dc to above 300 Hz. Stimulus sets were designed at each of three signal durations (125, 250, and 500 msec) by combining salient attributes, such as frequency (further divided into low, middle, and high regions), amplitude, direction of motion, and finger location. Estimated static information transfer (IT) was 6.5 bits at 500 mseC., 6.4 bits at 250 mseC., and 5.6 bits at 125 msec. Estimates of IT rate were derived from identification experiments in which the subject’s task was to identify the middle stimulus in a sequence of three stimuli randomly selected from a given stimulus set. On the basis of the extrapolations from these IT measurements to continuous streams, the IT rate was estimated to be about 12 bits/seC., which is roughly the same as that achieved by Tadoma users in tactual speech communication.     

高原低氧对脑功能的影响

本文报告了海拔4,000米左右低氧对脑功能的影响,并观察了高原现场驾驶汽车劳动6小时后脑功能的变化。所用测试指标如下:视觉机能(颜色分辨、深度觉、视觉疲劳和视觉注意稳定性等测验);听觉机能(听阈测验、听觉疲劳、声音强度辨别阈和声源定向等测定);记忆联想和演算能力测定;反应时和手脚协同活动反应;驾驶追踪动作和汽车穿桩实验等多种综合指标。结果表明,一些指标有影响,另一些指标没有影响。总的看来,海拔4,000米左右的高原现场对人的感觉机能和脑功能没有明显的影响。     

小学儿童记忆中组织策略发展的实验研究

本研究探讨了小学儿童组织策略的发展,结果表明:1.小学儿童组织策略的发展可分为产生性缺损和成熟运用组织策略两个主要阶段。第一个阶段根据是否伴随中介性缺损又可分为两个亚阶段。2.导致产生性缺损的原因有:(1)缺乏对记忆手段和记忆目标之间的功能关系的清晰认识;(2)不能清楚地认识策略的有效性,以及常运用自己熟悉的、简单的、但也相对无效的策略;(3)较差的有关记忆材料的知识基础以及较低的认识发展水平。     

PSYCHOBASIC: A BASIC dialect for the control of psychological experiments with the Commodore-64 and DELA interfacing

A modified version of BASIC for the control of psychological experiments is presented. PSYCHOBASIC runs on Commodore-64 computers with DELA interfacing, and it is based on Commodore BASIC. New commands control digital and analog input and output, centisecond timers, and counters. A control panel, which is displayed on the screen at all times, gives the status of many PSYCHOBASIC components. The interpreted nature of PSYCHOBASIC, as well as the control panel, makes the system easy to learn and use. The PSYCHOBASIC system is less expensive than equivalent systems for IBM-PC computers. A sample PSYCHOBASIC program is given.     

养育是一种幸福的体验吗？养育倦怠述评

养育倦怠指的是由于父母角色和长期的养育压力而导致的一组负性症状,具体包括与父母角色相关的极度耗竭感、与子女的情感疏远和父母角色的低效能感。学者们采用风险-资源平衡模型来对养育倦怠进行解释,并围绕其测量、前因变量和后果变量开展了一系列的研究。未来的研究应当重点关注以下问题：澄清养育倦怠的概念内涵,发展科学的测量与评价工具;重视养育倦怠与后果变量之间的关系及其作用机制;充分关注文化因素在养育倦怠研究中的地位和作用。     

同伴侵害对留守青少年主观幸福感的影响:自尊和社会支持的作用

采用追踪设计,对贵州省487名留守青少年进行间隔6个月的两次追踪调查,考察同伴侵害对男女留守青少年主观幸福感的影响以及自尊、教师支持和朋友支持在其中的作用。结果表明：（1）同伴侵害不仅能显著负向预测半年后留守青少年的主观幸福感,还能通过自尊的中介作用间接预测主观幸福感;（2）朋友支持可以显著缓解同伴侵害对男女留守青少年主观幸福感的消极影响：当朋友支持较低时,同伴侵害对男女留守青少年主观幸福感的消极作用显著,当朋友支持较高时则不存在显著影响;（3）教师支持可以显著缓解同伴侵害对留守女生主观幸福感的直接作用：相对于高教师支持的女生,同伴侵害对主观幸福感的影响在低教师支持的女生中更强;教师支持还可以调节留守女生同伴侵害与自尊之间的关系：相对于低教师支持的女生,同伴侵害对自尊的影响在高教师支持的女生中更显著。     

心理长度对二年级儿童数字线估计表征的影响

从心理长度的角度探讨二年级儿童在0~100和0~1000数字范围存在不同表征方式的原因。实验一要求二年级儿童完成长度均为10cm,范围分别为0~100和0~1000的数字线估计任务。实验二要求儿童对长度分别为10cm和18cm,范围均为0~1000的数字线进行估计。结果发现在两个实验中二年级儿童的估计均存在心理长度,但与以往研究的一年级儿童相比,心理长度的范围有所缩小。随着数字范围的增大或长度的减小,儿童的表征方式出现了从线性表征向对数表征的转变趋势。这些结果表明不精确的表征方式可能与心理长度策略的使用有关,心理长度在一定程度上影响了二年级儿童的估计表征方式。
