圣人之道，吾性自足：自我概念对生命意义的影响

生命意义是人类生命存在的永恒追求。东西方的理论均认为意义源于个体内在的自我结构,即自我概念。为了验证自我概念对生命意义的影响,对68名大学生进行实验研究。现场实验结果显示,控制生命意义基线水平和正负情绪后,自我概念仍显著预测生命意义;且自我概念提高组的生命意义得分显著高于降低组。行为实验结果显示,在高、低生命意义词汇记忆任务中,相比于低生命意义词,自我概念提高组对高生命意义词的再认率更高;相比于高生命意义词,自我概念降低组对低生命意义词的再认率更高。这些结果均表明,自我概念影响生命意义。结果暗示构建积极的自我概念形成强大的内心才是个体生命意义构建的根本途径。     

Planned Straight or Biased to Be So? The Influence of Visual Feedback on Reaching Movements

Abstract

Behavioral studies consistently find that subjects move their hand along straight paths despite considerations that suggest reaches should be curved. Literature on this topic makes it clear that the experimentally displayed feedback influences how subjects reach. Could the standard visual feedback, a displayed cursor, explain the lack of path curvature in experimental results? To address this question, we conducted three experiments to examine reach behavior in the absence of the standard visual feedback. In the first experiment, we found significant increases in curvature as visual feedback was progressively extinguished across groups. A second experiment revealed that practiced reaches became curved after the standard visual feedback was removed. A final experiment found that subjects’ reaches made before and after a brief display of visual feedback were similar, indicating a preference for specific curved trajectories. Our results suggest that the consistently straight reaches often observed could be due to a bias to move the displayed cursor straight, which when removed reveal subject-specific preferences for reaches that are often curved.     

The Influence of Trauma Symptoms on the Therapeutic Alliance Across Treatment

The authors examined the influence of early phase dissociation, interpersonal problems, and retraumatization on the therapeutic alliance at early, middle, and later treatment phases. Participants were 84 female survivors of child abuse (ages 18 to 60 years, 53.6% Caucasian) who were receiving counseling at a university training clinic. Master’s- and doctoral-level students provided counseling using integrated relationship and trauma-based cognitive behavior therapy. Treatment followed a 3-phase model. The authors used structural equation models to test the hypothesis. In the early and later phases, fewer interpersonal problems significantly predicted a stronger alliance. In the middle phase, fewer interpersonal problems, less dissociation, and more revictimization significantly predicted a stronger alliance. Tasks, goals, and bond contributed significantly to the alliance in each of the 3 phases. Interpersonal problems were consistently the strongest predictor across the 3 phases, whereas tasks consistently made the greatest contribution to the therapeutic alliance across all 3 phases.     

Repressive coping style and autonomic reactions to two experimental stressors in healthy men and women

Autonomic and affective responses to two different stress tasks were measured in 45 males and 74 females, categorized as repressive, true low-anxious, true high-anxious, and defensive high-anxious. Electrodermal activity (EDA) was used as a measure of sympathetic activity and the high frequency (HF) spectral component of heart rate variability as a measure of parasympathetic activity. Contrary to our predictions, reactivity of repressors did not differ from the reactivity of true low-anxious participants. The results draw attention to previous inconsistent findings within the literature on repressive coping style and autonomic nervous system dysregulation. It is suggested that future research could benefit from the use of more consistent operationalizations of the repressive coping construct and from comparing alternative measures of repressive coping within the same study.

Experimental analyses of gene-brain-behavior relations: some notes on their application.

The fields of genetics and neuroscience are yielding findings useful in understanding complex behavior-environment relations. We believe that these developments in interdisciplinary basic research are of interest to applied behavior analysts because of the long history of basic findings being used by the readership of the Journal of Applied Behavior Analysis to improve everyday human activities. An awareness of contemporary developments in a range of basic research disciplines may facilitate the systematic replication of those functional relations in applied settings. In this context, we selectively review papers published in the Journal of the Experimental Analysis of Behavior and other basic research journals that relate to gene-brain-behavior relations.     

客体与空间工作记忆的分离：来自皮层慢电位的证据

利用128导事件相关电位技术,采用延迟匹配任务的实验范式,测查了16名正常被试在完成客体任务和空间任务时的皮层慢电位（slow cortical potentials,简称sp成分）,实验发现：在后部脑区,客体工作记忆与空间工作记忆在慢波活动的时间上存在分离,空间任务更早的诱发出负sp成分,并且空间任务激活更多的后部脑区;左下前额叶在客体工作记忆任务与空间工作记忆任务中都有激活,并且激活强度不存在显著差异;背侧前额叶主要负责客体信息的保持与复述,但左右背侧前额叶的激活强度存在不对称性。     

知觉与行为的分离在视错觉研究中的验证

知觉与行为的分离是指人的视觉对物体的知觉与对行为的控制属于两个不同的系统。最早人们从临床病例中发现存在知觉与行为的分离,以后Aglioti等利用铁钦纳错觉实验证实正常人中也存在这一分离现象。一些研究者将两者的分离看作是两个不同视觉皮层通路（腹侧知觉系统和背侧视觉运动系统）的结果。围绕这一分离现象的实验和假说引发了不少的争论。该文回顾了十年来利用错觉实验所做的众多验证性研究,分析了支持和否定分离现象存在的各类证据,对一些重要结果和观点进行了总结,并由此提出了自己的看法。
