消费者不道德行为与员工情绪衰竭关系的调节性中介模型

大量研究业已揭示,消费者针对员工的不道德行为是导致员工情绪衰竭的重要因素,但是对于消费者不针对员工的不道德行为（consumer unethical behavior that are not employee directed,CUB）是否会影响员工的情绪衰竭,研究还较少涉及。基于道义伦理学,本研究提出了一个调节性中介模型,以分析CUB与员工情绪衰竭的关系。该模型假定,CUB与员工情绪衰竭之间的关系以情绪抑制为中介,并且受到员工道德认同的调节。对198名销售人员的研究发现,即使控制了消费者针对员工的不道德行为,CUB仍影响着员工的情绪衰竭;CUB与员工情绪衰竭的关系受到道德认同的调节,道德认同较高的员工表现出较高程度的情绪抑制与情绪衰竭。研究支持了假设的调节性中介模型,情绪抑制在CUB和情绪衰竭之间发挥着部分中介作用,不仅如此,这一中介作用还受到道德认同的调节,情绪抑制在CUB和情绪衰竭之间的间接效应主要表现在道德认同较高的员工中。最后探讨了研究发现的理论意义、不足及未来发展方向。     

Thought Suppression in Spider-Fearful and Nonfearful Individuals

The authors examined the suppression of spider-related thoughts in spiderfearful (n = 23) and nonfearful (n = 22) individuals. Participants were primed with vivid pictures of spiders and a story about spiders. Next, they were randomly assigned to 1 of 2 conditions: (a) suppression of thoughts associated with the previously presented spiderrelated stimuli or (b) free expression of any thoughts, including those related to the spider-related stimuli. All participants completed a subsequent free-expression exercise. Results indicated that spider-fearful individuals expressed thoughts about the spider-related stimuli for a longer length of time than did nonfearful individuals, particularly in the suppression condition. Participants in both groups demonstrated a rebound of thoughts associated with the spider-related stimuli following suppression. The authors propose that the priming of feared stimuli makes suppression of fear-related thoughts particularly difficult for fearful individuals, perhaps by activating a state of heightened arousal.     

Role of prior negative cognitions on the development of intrusive thoughts

This analogue study examined how individuals' prior negative cognitions influenced intrusion frequency, intrusion‐related distress and thought suppression. Participants at high (HR) and low risk (LR) for interpreting their intrusive thoughts in a negative manner viewed a graphic trauma film and their subsequent intrusion development was assessed. HR participants experienced a greater frequency of intrusions and intrusion‐related distress compared to LR participants. Trait thought suppression moderated the relationship between risk for the negative interpretation of intrusions and intrusion frequency. The findings suggest that pre‐existing negative cognitions are influential in the development of intrusions following exposure to an analogue trauma.     

认知重评和表达抑制情绪调节策略的脑网络分析：来自EEG和ERP的证据

本文旨在对认知重评和表达抑制两种常用情绪调节策略的自发脑网络特征及认知神经活动进行深入探讨。研究采集36名在校大学生的静息态和任务态脑电数据,经过源定位和图论分析发现节点效率与两种情绪调节显著相关的脑区,以及脑区之间的功能连接。研究结果表明,在使用认知重评进行情绪调节时会激活前额叶皮质、前扣带回、顶叶、海马旁回和枕叶等多个脑区,在使用表达抑制进行情绪调节时会激活前额叶皮质、顶叶、海马旁回、枕叶、颞叶和脑岛等多个脑区。因此,这些脑区的节点效率或功能连接强度可能成为评估个体使用认知重评和表达抑制调节情绪效果的指标。     

Magnocellular facilitation of flanked-letter identification disappears with strong flanker interference

Previously, we obtained evidence to suggest that the magnocellular system may reduce interference from flankers during flanked-letter identification. To understand this phenomenon better, we combined the data of our previous experiments, which all used the same flanking letter, and focused on the different target letters that were used. The new analysis showed that after an initial increase, magnocellular facilitation decreased and ultimately disappeared, as the target–flanker combination's level of interference increased. The initial increase was partly while the later decrease was fully replicated in two new experiments that focused on two different target letters while manipulating flanker identity. The outcome of a third new experiment studying the type of interference reduced suggested that although crowding contributed to total interference, it was insensitive to magnocellular mediation. Our results may be understood to reflect the involvement of the magnocellular system in an attentional-selection mechanism that is silenced by surround suppression.     

Tactile Ranschburg effects: facilitation and inhibitory repetition effects analogous to verbal memory

The present paper examines the effect of within-sequence item repetitions in tactile order memory. Employing an immediate serial recall procedure, participants reconstructed a six-item sequence tapped upon their fingers by moving those fingers in the order of original stimulation. In Experiment 1a, within-sequence repetition of an item separated by two-intervening items resulted in a significant reduction in recall accuracy for that repeated item (i.e., the Ranschburg effect). In Experiment 1b, within-sequence repetition of an adjacent item resulted in significant recall facilitation for that repeated item. These effects mirror those reported for verbal stimuli (e.g., Henson, 1998a Henson, R. N. A. (1998a). Item repetition in short-term memory: Ranschburg repeated. Journal of Experimental Psychology: Learning, Memory, and Cognition, 24(5), 1162–1181. doi:doi.org/10.1037/0278-7393.24.5.1162[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]. Item repetition in short-term memory: Ranschburg repeated. Journal of Experimental Psychology: Learning, Memory, and Cognition, 24(5), 1162–1181. doi:doi.org/10.1037/0278-7393.24.5.1162). These data are the first to demonstrate the Ranschburg effect with non-verbal stimuli and suggest further cross-modal similarities in order memory.
