Locus of Control and Voluntary Heart-Rate Change

Summary: Investigated the effects of locus of control on voluntary control of heart-rate change. The 32 subjects were randomly assigned to one of two heart-rate change groups: Increase or decrease. The groups were counterbalanced for locus of control and sex. No heart-rate feedback was provided to subjects, and all subjects performed the appropriate task for two sessions. Results indicated that during the initial session, internals were better able to increase their heart-rates than externals; the externals were better able to decrease their heart-rates than internals. This association, however, diminished to nonsignificance in the second session.     

The Effect of Order and Rate of Presentation of Stimuli Upon the Establishment of a Conditioned Discrimination

The modified interfering cue theory put forward by Fletcher et al. (2) to explain performance in the ambiguous cue problem (ACP) was examined. Eight-year-old children were first trained to acquire response tendencies to the individual cues of this problem. When presented subsequently with the problem, the children showed marked differences in the number and type of errors made. The results were interpreted as supporting the theory of Fletcher et al. It was also suggested that the cues with clear positive or negative values were employed by the subjects to limit or neutralize the interference caused by the ambiguous cue.     

自我威胁刺激对返回抑制的影响

使用线索-靶子范式,分别将面孔刺激作为线索(实验1)和靶子(实验2)呈现,考察自我扭曲面孔对返回抑制的影响。结果发现:自我扭曲面孔为线索时,与他人扭曲、他人中性面孔产生了实验性分离,自我扭曲面孔的返回抑制效应量最小;自我扭曲面孔为靶子时,返回抑制消失。研究结果揭示:以自我扭曲面孔为代表的自我威胁刺激激活了威胁性自我概念,缩小了注意搜索范围,可能是导致人际紧张的潜在自我认知机制。     

皮亚杰对当代社会认知研究的影响

1　引言　　皮亚杰是瑞士著名的心理学家 ,他继承西方哲学中康德的传统 ,在消除英国经验主义和德国唯心主义思想水火不相容的对立之后 ,以建构主义的思想回答知识获得的最一般的、最基本的条件这一问题 ,创立了发生认识论。发生认识论就是要解决人是怎样从低级水平的认识过渡到高级水平的认识的。心理学承担着解释这种“过渡”的任务 ,其手段就是对智慧的分析和刻画。从 2 0世纪 2 0年代开始 ,皮亚杰以结构主义为方法论 ,采用临床法对儿童心理进行了长达 5 0多年的研究 ,以验证和丰富其发生认识论。发生认识论的核心是主客体相互作用的儿童…     

目标定向对创造性个性的影响

基于创造性研究的社会心理学取向,本研究试图探讨目标定向干预对创造性个性的影响。对73名高一学生施以TARGET模式3个月以引导掌握定向的形成;另73名高一学生作为控制组。协方差分析表明,实验组的创造性个性有明显改善;被试实验前的目标定向对实验效果具有一定的影响,实验前成绩接近定向的倾向较弱的被试其创造性个性的改善较为明显。总之,目标定向干预可导致创造性个性的改善。     

The Influence of Background Stimuli on Summation in Autoshaping

Five experiments examined the factors that determine whether or nor summation will occur when experimental stimuli are presented on a television screen for autoshaping with pigeons. In Experiment 1 there were periods when the television screen was illuminated white and periods when it was dark. When conditioning was conducted during the white periods, then summation was observed if the test trials were conducted with a white screen during the intertrial interval. Summation was not found when conditioning was conducted during the dark periods, no matter how testing was conducted. The remaining experiments demonstrated that summation will occur if at least some of the conditioning trials are conducted with the experimental stimuli being accompanied by white illumination in the remainder of the television screen. It was not necessary for this illumination to persist into the interval between trials. These findings indicate that summation is influenced by the similarity of the patterns of stimulation that are used for training and testing.     

偏差声音干扰刺激对视觉注意网络系统的影响

结合注意网络测量工具和听视ODDBALL干扰范式,考察偏差声音干扰刺激的出现对注意网络系统不同功能的影响。结果发现,声音刺激序列下,视觉线索唤醒效应均消失; 标准声音刺激下,不存在线索的脱离和转移效应; 偏差声音刺激下,出现线索脱离和转移效应。研究表明,注意网络中的警觉功能具有超通道加工机制,偏差刺激下视觉注意系统中注意定向和线索转移效应的出现表明偏差干扰效应主要由偏差刺激引起的注意脱离和注意转移损耗部分引起。

On Lions and Adolescents: Affective Temperaments and the Influence of Negative Stimuli on Memory

The present study investigated the relation between reaction to negative stimuli and memory for stimuli. The relation was further investigated using as a framework individuals’ affective temperaments (AFTs). Eighty adolescents participated in the study. The AFTs are based on selfreported affect and categorizes individuals in four temperaments: self-actualizing, high affective, low affective and self-destructive. Reaction to negative stimuli was measured by interpretation of specific words in a short story. Two days later, participants were presented with a list of words and asked which of them were present in the short story. Individuals’ AFTs were expected to predict the promotion of pleasure or the prevention of displeasure. On a general level, reaction to negative stimuli predicted memory for negative, positive and neutral words. At an individual level, self-actualizers and high affectives’ negative reaction predicted the memory of positive words (i.e., promotion). In contrast, low affectives’ negative and positive reaction predicted the memory of neutral words (i.e., prevention).

Effects of Job Conditions on Worker Perceptions: Ambient Stimuli vs. Group Influence1

This study identifies the direct effects of objective job conditions on individual perceptions of job conditions. The assumptions that (1) group perceptions mediate the relationship between objective job conditions and individual perceptions of job conditions, and (2) group consensus enhances the relationship be-between group perceptions and individual perceptions were tested. Respondents were white, male, blue collar workers (N= 1240) in a tire and rubber manufacturing plant. Work groups (N= 156), consisting of four or more men on the same shift, in the same department, and who had the same supervisor, were identified. Objective job conditions included work group size, pay style, shift, and job technology. Group and individual perceptions of amount of work-load, role conflict, responsibility pressure, and intrinsic rewards were measured. The findings indicated that objective job conditions have important effects on individual perceptions of stressful and rewarding job conditions. Smaller work groups, and jobs that pay on an hourly rather than a piece-work basis, allow for some control over the pace of work, and allow for interaction among fellow workers resulted in higher levels of intrinsic rewards and lower levels of workload, role conflict, and responsibility pressures. An intriguing pattern appeared where, in perceptions involving interpersonal relations, work group influence was relatively more important than objective job conditions. When assessing task oriented aspects of work, objective job conditions were more important than group perceptions.     

The Influence of Masked Stimuli on Response Selection: Evidence from a Semantic Categorization Task

Unconscious visual stimuli can be processed by human observers and influence their behaviour. A striking example is a phenomenon known as “free-choice priming,” where masked “prime” stimuli—of which participants are unaware—modulate which of two response alternatives they are likely to choose. Recent efforts to uncover the mechanisms underlying this intriguing effect have revealed that free-choice priming can emerge even in the absence of automatized stimulus-response (S-R) associations between masked primes and specific motor responses, indicating that free choices can be influenced by a masked prime’s meaning (Ocampo, 2015). It remains unknown, however, whether masked primes bias response selections because they are implicitly classified according to task instructions, or because spreading activation occurs within the prime's semantic network. To adjudicate between these two possibilities, participants in the present experiment categorised targets as either animals or people and selected which of two response alternatives they wanted to make following presentation of a free-choice target. Crucially, while implicit classifications could proceed during processing of both animal and person masked primes, only animal primes could trigger spreading activation within their semantic network. This manipulation modulated free-choice priming; only masked animal primes influenced response selections to free-choice targets. This result indicates that an automatic spreading activation mechanism might underlie a masked prime’s ability to influence free-choice responses.
