Adult Age Differences in the Ability to Mentally Transform Object and Body Stimuli

ABSTRACT

Cognitive neuroscience literature suggests a strong dissociation between the ability to mentally transform object and body stimuli (Hegarty & Waller, 2004 Hegarty, M. and Waller, D. 2004. A dissociation between mental rotation and perspective-taking spatial abilities. Intelligence, 32(2): 175–191. [Crossref], [Web of Science ®] , [Google Scholar] ). However, little is known about how this ability changes with age. This dissociation was explored in 20 younger (19–24 years) and 20 older (65–87 years) adults. Mental rotation of object stimuli was demonstrated for both age groups, suggesting that the neuro-cognitive network involved with performing (object-based) mental transformations is relatively preserved in older age. Compared to young adults, older adults displayed the greatest decline in performance efficiency for the whole-body task. The authors propose that an age-related decline in the integrity of body-schema information may account for this change.     

Perceptual Delay of the Second of two Adjacent Stimuli in a Large Body Movement

Conscious perception of the apparent time of occurrence of the second of two closely spaced stimuli was examined using an’ extended movement A considerable perceptual delay was found whether or not the response to the second stimulus curtailed the primary response. This delay was found whether the second stimulus occurred during the movement response to the first stimulus or during the reaction time to the first stimulus. At present there appears to be no satisfactory explanation of the phenomenon.     

The Structural Aspects of Schizophrenic Responses to Auditory Stimuli

The function of reinforcement as a performance versus a learning variable was examined with the use of a number of varying imitation training conditions. Forty white and 40 black Ss were used. The analysis consisted of five 2 (Testing Situation) × 2 (White versus Black children) × 8 (Training Conditions) factorials with the use of an analysis of variance technique. The results question the hypothesis that reinforcement is only a performance variable. Partial support is provided for the assumption that imitative behavior may be maintained through similarity of responding where imitation has been acquired through a strong history of reinforcement for imitation. Few racial differences were discovered.     

不同程度考试焦虑个体对威胁性刺激注意机制的差异

本研究采用线索提示实验范式,旨在考察考试焦虑个体对与考试有关和与考试无关刺激在注意机制上的差异。研究选取被试149名,分别采用TAS,STAI-T以及BDI量表进行高、低考试焦虑被试的筛选。问卷结果显示,TAS与STAI-T、BDI均有较高的正相关。行为实验结果显示,高、低考试焦虑个体对与考试相关的刺激在注意卷入上不存在显著差异,但是与低考试焦虑个体相比,高考试焦虑个体对与考试相关的刺激上出现了注意脱离困难。     

人类对情绪事件效价强度的易感性及神经机制

人类情绪无疑有强度的差异。然而, 长期以来人类情绪强度的易感性未能引起足够关注。通过系统操纵刺激材料的效价强度, 作者及研究团队分别从情绪易感性本身, 情绪影响高级认知, 以及个体差异三个层次系统探讨了人类对情绪事件效价强度的易感性及其神经机制。结果发现：1)、相比正性刺激, 人类对负性刺激的效价强度更敏感, 这一效应可能跟右侧海马/杏仁核的警觉功能有关联。2)、与上述结果相一致, 不同效价强度的负性情绪对新异性加工、目标觉察、执行控制等高级认知过程具有显著不同的影响。3)、人类情绪强度的易感性具有显著个体差异：相比男性, 女性对轻度负性情绪事件易感性更强。相比中向人群, 外倾人群对愉悦刺激的情绪易感性更强, 而对轻度负性事件的情绪易感性更弱。

青少年创伤后应激障碍症状与网络成瘾症状的关系：惩罚敏感性和孤独感的中介及性别的调节

汶川地震9.5年后,对汶川县和都江堰市767名中学生进行调查,考察惩罚敏感性和孤独感在创伤后应激障碍症状和网络成瘾症状之间的多重中介作用及性别差异。结果发现：（1）PTSD症状正向预测网络成瘾症状,并分别通过惩罚敏感性、孤独感的单独中介作用及两者的链式中介作用显著预测网络成瘾症状;（2）女性的PTSD症状显著正向预测网络成瘾症状,并分别通过惩罚敏感性和孤独感间接影响网络成瘾症状;男性的网络成瘾症状仅被PTSD症状正向预测。     

The Extended Body: The Social Body of Jesus according to Luke1

Abstract : Informed by body phenomenology and contemporary concepts of the social body, this article aims to interpret the particular movements and transformations of Jesus’ body as presented in the Gospel of Luke. From the outset Jesus’ body is inscribed in a Jewish genealogy. Likewise, the Gospel depicts the character of Jesus via the various landscapes he passes through as well as through the social interactions of which he is a part. While Jesus’ body is initially described as being energized by the mobile presence of the Spirit, it increasingly closes in and, at the end, simply disappears. Luke describes Jesus’ ascension and resurrection as radical transformations of Jesus’ body, by which Jesus’ body‐and‐mind (Leib) extends into a social body, at home in God as well as among his followers. This social body also crosses the genetic and cultural boundaries between Jews and Gentiles. Only through this extensiveness can Jesus’ body become accessible worldwide.     

FN400和N400是相同的ERP成分：来自图形材料的证据

本研究通过比较记忆编码阶段语义启动引起的N400效应和提取阶段熟悉性引起的FN400效应的地形图考察图形材料诱发的N400和FN400是否是相同的ERP成分。实验结果发现,语义启动引起的N400效应和熟悉性引起的FN400效应的地形图没有显著差异。这说明图形材料诱发的FN400和N400是相同的ERP成分,两者都反映了语义加工。本研究为FN400效应反映了语义启动而不是熟悉性的观点提供了新的实验证据。     

大学生社交焦虑对躯体变形障碍的影响：外表拒绝敏感性的中介作用

躯体变形障碍在大学生群体中具有较高的发病率,在其发展过程中,社交焦虑是重要的预测因素;然而两者潜在的中介机制却未得到研究者关注。本研究采用问卷调查法,旨在大学生 (N = 875)中探究外表拒绝敏感性在社交焦虑与躯体变形障碍之间的中介作用。结果发现： (1) 社交焦虑显著正向预测外表拒绝敏感性与躯体变形障碍,且外表拒绝敏感性显著正向预测躯体变形障碍; (2) 外表拒绝敏感性在社交焦虑与躯体变形障碍之间具有显著的部分中介作用。本研究发现,个体的社交焦虑可直接影响躯体变形障碍,也可通过提高外表拒绝敏感性间接影响。     

Effect of Thermal Need on Responses to Pictorial Stimuli

In order to provide more rigorous experimental evidence on the question of need projection in thematic materials, 72 U. S. Army enlistee volunteers were subjected to systematically varying degrees of body cooling and confronted with pictorial stimuli, varying in relevance, to which they could make quantifiable vicarious heat-seeking responses. Thermal need was independently assessed as a negatively accelerated inverse function of ambient temperature, and responses to the most relevant stimuli provided conclusive evidence of need projection as a similarly accelerated function. Scenes which differentiated significantly between thermal conditions were those which suggested the more immediate and thorough reduction of thermal discomfort. The relevance of results to studies of motivated perception was discussed.

刺激同一性对错误后反应的影响

当错误发生后,人们往往会放慢错误后反应的速度,以避免错误的再次发生,许多研究者认为,这是自上而下的认知控制对错误后反应的影响.为了探讨刺激属性是否也在错误后的反应中起作用,本研究从刺激同一性角度出发,探讨错误反应刺激与错误后刺激的同一性以及反应-刺激间隔时间(RSI)对错误后反应的影响.结果发现,当错误后的刺激与错误反应的刺激一致时,可减小错误后反应时延长的程度,同时,RSI越大,PES越小.本研究得出结论,刺激同一性和RSI作为自下而上的刺激驱动在PES的产生过程中发挥了作用.
