回视引导机制:言语记忆与空间记忆之争

创业是一个过程化的概念,以创业者的认知特征作为研究焦点有助于发现新问题。本文以此为主线,试图回答三个问题。①创业行动：为什么某些人成为创业者？②创业决策：为什么某些人意识到商机？③创业结果：为什么某些人创业取得成功？     

美军EPAS系统对我军士兵职业分类研究的启示

EPAS（Enlisted Personnel Allocation System）是美军新开发的军人选拔分配系统。该系统采用最优线性匹配程序,通过预测绩效最大化,提高应征人员岗位匹配的有效性,以满足部队兵员分配的需求。本文从美军应征人员分配标准出发,介绍了该系统的历史沿革、主要原理,并阐明了对我军士兵职业分类研究的启迪。     

动作的主动控制感与因果关系的主动控制感：主动动作时间压缩效应的产生机制

主动动作的时间压缩效应指主动动作到动作结果之间存在时间上的主观压缩。基于动作的主动控制感和因果关系的主动控制感是该效应的两种理论解释。本文首先分别介绍动作的主动控制感和因果关系的主动控制感, 并从行为和脑机制角度提供相应的证据解释时间压缩效应的机制。同时, 本文提出了在主动动作时间压缩效应中动作的主动控制感与因果关系的主动控制感之间可能存在的序列加工和平行加工的关系。     

相貌负面身体自我女性对相貌词的注意偏向眼动的证据

采用改进的点探测范式并结合眼动技术, 以相貌词(积极和消极)为刺激材料, 实验中积极相貌词?中性词、消极相貌词?中性词、积极相貌词?消极相貌词以及中性词?中性词配对呈现, 考察了相貌负面身体自我女性对相貌词的注意偏向及其时间进程。眼动数据的结果发现, 在积极相貌词?中性词和消极相貌词?中性词条件下, 与控制组相比, 相貌负面身体自我女性的首视点更频繁地指向消极相貌词, 对消极相貌词探测速度更快, 并且首视点维持在此类词语上的时间更长, 但未发现总体的注视时间偏向; 与积极相貌相比较时, 相貌负面身体自我女性呈现与上述相同的结果, 此时的注意模式为警觉?脱离困难。此外, 相貌负面身体自我的女性还表现出对积极相貌词的减速探测偏向。行为证据进一步显示, 相貌负面身体自我女性对消极相貌词存在注意脱离困难。在积极相貌词?消极相貌词配对条件下, 相貌负面身体自我女性对消极相貌词也表现出注意脱离困难。以上结果表明, 相貌负面身体自我女性对消极相貌词表现出警觉?脱离困难的注意偏向。     

幼儿友好型内隐联想测验的建构及有效性

本研究依据经典IAT (Implicit Association Test)的核心原理构建了幼儿友好型内隐联想测验(Preschooler-friendly Implicit Association Test, PSF-IAT)。它由两部分联结任务组成, 以反应时为指标, 通过对概念刺激和属性刺激之间自动化联系的评估进而对幼儿的内隐态度进行间接测量。本研究采用两种方式对PSF-IAT范式的适用性进行验证：首先, 将PSF-IAT用于测试幼儿对花和虫的态度, 检验该范式在非社会范畴概念态度研究中的可行性; 其次, 将PSF-IAT用于测试幼儿内隐种族态度, 并验证其与另一种幼儿内隐态度测试方法间结果的相关性, 检验该范式在社会范畴概念态度研究中的可行性。研究结果表明, PSF-IAT符合学前儿童认知发展与行为反应的特点, 能有效测量幼儿的内隐态度。     

执行功能与儿童流行性肥胖的关系

流行性肥胖被认为是由于能量摄入和能量消耗间长期的不平衡导致的一种反常的、脂肪堆积过多的状态, 近期研究发现执行功能与儿童流行性肥胖关系密切。与正常体重儿童相比, 肥胖儿童执行功能差主要体现在抑制控制上, 他们难以抑制对食物线索的注意, 并且更容易对其做出冲动反应, 表明他们干扰抑制中的注意抑制以及反应抑制存在不足。脑机制研究发现, 前额皮质(PFC)与肥胖关系密切, 肥胖被试对食物线索表现出较低的眼窝前额皮质(OFC)激活水平与较高的背外侧前额皮质(DLPFC)激活水平; 奖励回路也与肥胖密切相关, 肥胖或许是由PFC与奖励回路间复杂的相互作用引起的。执行功能与流行性肥胖之间可能是双向作用关系, 执行功能差可能是个体BMI增加的潜在因素, 而肥胖个体的体重减少在一定程度上则有助于其执行功能改善。少量对儿童肥胖的干预研究表明执行功能训练或许在减肥效果保持上有一定优势, 未来研究应当关注对执行功能, 尤其是抑制控制进行有效训练的方法, 并将其与其他干预方式结合, 更好地解决儿童流行性肥胖问题。     

Temporal Doppler Effect and Future Orientation: Adaptive Function and Moderating Conditions

The objectives of this study were to examine whether the temporal Doppler effect exists in different time intervals and whether certain individual and environmental factors act as moderators of the effect. Using hierarchical linear modeling, we examined the existence of the temporal Doppler effect and the moderating effect of future orientation among 139 university students (Study 1), and then the moderating conditions of the temporal Doppler effect using two independent samples of 143 and 147 university students (Studies 2 and 3). Results indicated that the temporal Doppler effect existed in all of our studies, and that future orientation moderated the temporal Doppler effect. Further, time interval perception mediated the relationship between future orientation and the motivation to cope at long time intervals. Finally, positive affect was found to enhance the temporal Doppler effect, whereas control deprivation did not influence the effect. The temporal Doppler effect is moderated by the personality trait of future orientation and by the situational variable of experimentally manipulated positive affect. We have identified personality and environmental processes that could enhance the temporal Doppler effect, which could be valuable in cases where attention to a future task is necessary.     

Effects of top-performer rewards on fellow salespeople: a double-edged sword

Rewarding top performers is of strategic importance to the sales organization. Top-performing salespeople not only contribute significantly to the success of their firm but may also motivate the skill development of peer salespeople. However, both academic research and anecdotal evidence suggest that top performer rewards can boomerang by damaging peer salespeople's morale and productivity, although the underlying mechanisms and boundary conditions remain unclear. Using a sample of salespeople and their managers from financial investment firms in Taiwan, the authors uncover both positive and negative effects of top-performer rewards. Specifically, it is found that when behavior control is employed, top-performer rewards are positively associated with perceived top-performer customer-relationship-building competence only when overall organizational justice is high. By contrast, when organizational justice is low and behavior control is employed, top-performer rewards give rise to perceived favoritism. Moreover, in large sales units, top-performer rewards are much less likely associated with perceived favoritism when organizational justice is high. It is through the perceived top-performer customer-relationship-building competence and perceived favoritism that top-performer rewards have a double-edged sword effect on fellow salespeople's selling skills, opportunism, and sales performance. Theoretical and managerial implications are discussed.     

Meaning in Life Promotes Proactive Coping via Positive Affect: A Daily Diary Study

Previous research on meaning in life and coping has generally been focused on reactive coping strategies and global meaning judgments. To extend this, the present study used a daily diary method to collect longitudinal data, and examined whether individuals’ daily meaning in life predicted use of proactive coping techniques and whether this relationship was mediated by positive affect. Adults (n = 132) completed a diary to track their meaning in life and positive affect every day for 21 consecutive days. Global levels of meaning in life, positive affect, and proactive coping were measured both at baseline and after the daily reporting phase ended. Hierarchical linear modeling demonstrated that daily meaning in life was a positive predictor of daily positive affect. Furthermore, combined latent growth curve and structural equation models indicated that the rate of change in daily meaning in life predicted change in proactive coping over the course of the study, and that this relationship was mediated by change in positive affect. The mediational effect of positive affect in the relationship between meaning in life and proactive coping was also verified by the reported global levels of these variables. These findings suggest that meaning in life may play an important role in coping with future life stress. Our discussion centers on the positive functions of meaning in life and the mechanisms of the predictive relationship of meaning in life in terms of proactive coping.     

语境丰富性和生词重复暴露对儿童附带性词汇学习的影响

考察了重复阅读下语境丰富性和生词重复暴露对儿童附带性新词学习的影响。实验设为三种学习条件:多语境重复、单语境重复、基线。结果显示,在反映词汇加工早期阶段的凝视时间和晚期阶段的总注视时间上,均表现为多语境重复学习后的词汇加工时间显著短于单语境重复条件和基线条件,且后两者间无差异。结果证明,儿童在重复阅读过程中对丰富语境线索的使用是附带性词汇学习发展的主要原因,而生词单纯的重复暴露并未产生明显效果,进一步表明只有在丰富的语境环境下单词的重复才会提高儿童新词学习的质量。关于语境丰富性和重复在附带性词汇学习理论和语文实践教学价值上的启示将被讨论。
