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.

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.     

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.     

触觉刺激对触觉注意启动作用的研究

目的：探讨触觉刺激对触觉注意的影响,以揭示选择性注意的机制。方法：利用在体电生理记录技术,记录了288个丘脑腹侧基底核（ventrobasal nuleus of thalamus,VB）神经元放电活动,并着重考察了不同强度触觉刺激对丘脑神经元细胞自发放电活动的影响。结果发现：触觉刺激对大部分的触觉神经元的自发放电活动均有抑制性影响。提示触觉刺激降低背景噪声可能是触发选择性触觉注意的神经机制。     

The Silence of the Body

As a practice meant to release the subject from the narcissism that informs the concerns and preoccupations of her or his ego, psychoanalysis aims at a transformation of the subject comparable to the Buddha's quest for enlightenment. In order to clarify this subtle and difficult dimension of psychoanalytic work, this essay draws upon a clinical example and discusses it in the context of both Freud's and Lacan's ideas about the role of narcissism in the formation of the ego, and the Buddha's doctrine of Anatta, which insists that the concept of the Atman, or self, is based upon an illusory thought.     

与恐惧相关的简化刺激在不同知觉负载条件下的注意捕获效应

本研究选用视觉搜索范式,探讨了与恐惧相关的简化刺激在不同知觉负载条件下的注意捕获效应。结果发现:在分心物刺激为清晰的条件下,与恐惧相关的分心物刺激能够优先捕获被试注意,即使分心物刺激在一定程度上被简化,与恐惧相关的简化分心物刺激依然具有加工优先权,并且与恐惧相关的简化刺激在低知觉负载条件下和高知觉负载条件下的注意捕获量并没有显著差异,这一结果表明,与恐惧相关的简化刺激不受知觉负载的限制,能够自动化加工。     

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.

The Development of Infants' Sensitivity to Arbitrary Intermodal Relations

The development of infants' ability to detect the arbitrary relation between the color/shape of an object and the pitch of its impact sound was investigated using an infant-control habituation procedure. Ninety-six infants of 3, 5, or 7 months were habituated to films of two objects differing in color and shape, striking a surface in an erratic pattern. One object produced an impact sound of a high pitch, and the other object produced a low pitch. During test trials, infants in the experimental conditions received a change in the pairing of pitch with color/shape, whereas controls received no change. Results indicate that visual recovery to the change in pitch-color/shape relations was significantly greater than that of age-matched controls at 7 months, but not at 3 or 5 months. A prior study demonstrated that by 3 months, infants were able to discriminate the color/shape and pitch changes of these events. However, it is not until 7 months that they show evidence of detecting the arbitrary relation between these attributes.     

The Function of Intensity in the Spatial Summation of Subliminal Stimuli in the Retina

Each of 12 rats was subjected to a conventional three-phase behavioral contrast paradigm. No positive behavioral contrast was observed in any S, although 11 rats showed very strong extinction effects. Three rats showed negative induction, eight showed no increase in response rate in the constant component, while one rat showed first a positive then a negative induction effect. The results were discussed in terms of both Reynolds' and Terrace's hypothesis and related to the recent research on autoshaping.     

Influence of Rhythmic Sensory Stimuli Upon the Heart-Rate

Eighteen retarded adults, divided into three groups equated for IQ, MA, and number conservation performance, received addition-subtraction and reversibility training under either cognitive-conflict or nonconflict conditions, or received no training. Under cognitive-conflict, transformation of one of two sets of discrete elements produced a perceptual illusion, and the addition-subtraction and reversibility operations applied to that set produced conflict between its length and density. Under nonconflict, simultaneous application of the operations to both sets avoided such conflict. Both training groups made significant gains from pretest and significantly exceeded controls in posttest number conservation (ps < .05). Lack of differential gains by the training groups suggested that cognitive conflict is not essential to induce number conservation.     

Slow Motor Responses to Visual Stimuli of Low Salience in Autism

ABSTRACT

The authors studied 2 tasks that placed differing demands on detecting relevant visual information and generating appropriate gaze shifts in adults and children with and without autism. In Experiment 1, participants fixated a cross and needed to make large gaze shifts, but researchers provided explicit instructions about shifting. Children with autism were indistinguishable from comparison groups in this top-down task. In Experiment 2 (bottom-up), a fixation cross remained or was removed prior to the presentation of a peripheral target of low visual salience. In this gap–effect experiment, children with autism showed lengthened reaction times overall but no specific deficit in overlap trials. The results show evidence of a general deficit in manual responses to visual stimuli of low salience and no evidence of a deficit in top-down attention shifting. Older children with autism appeared able to generate appropriate motor responses, but stimulus-driven visual attention seemed impaired.
