Squirrel monkeys were restrained in a chair equipped with a tail-shock apparatus and a pneumatic bite hose located in front of the subject's face. An aggressive response was recorded when the monkey bit the hose. Initial sessions in which no shocks were delivered produced some biting. When biting during these sessions stabilized at a near-zero level, regularly scheduled shocks were delivered to the monkey's tail, causing a consistently higher rate of biting. After several sessions under these conditions, a punishment phase was introduced in which the previous shock conditions were maintained, and every bite was followed immediately by another, more intense shock. Biting under these conditions was suppressed to a near-zero level. When the punishment contingency was removed, biting increased. With one subject, two additional bite-contingent stimuli were examined: (1) a milder shock that, when made contingent upon hose biting, also suppressed that response, and (2) a contingent tone that had no obvious suppressing or facilitating effect. Individual differences among subjects were extreme, but the effect of bite-contingent shock was consistent. Observations of the subjects during the punishment sessions indicated the existence of certain side effects that resulted from the use of punishment to suppress shock-induced aggression. 相似文献

Psychophysiological process and outcome phenomena were analyzed to examine differential temporal patterns within and across cognitive, behavioral and physiologically-based treatments of agoraphobia. Eighty-eight severe and chronic agoraphobics with panic attacks (DSM-III) were randomly assigned to one of three treatments: Paradoxical Intention, Graduated Exposure or Progressive Deep Muscle Relaxation Training. Protocol therapists, whose treatment integrity was objectively monitored, conducted 12 two-hour weekly sessions. All subjects received programmed practice instructions concurrent with their primary treatment. Analyses revealed numerous significant reductions on in vivo psychophysiological measures for the relaxation condition, a few improvements for the exposure treatment and no effects for the paradoxical intention modality. The mediating role of pretreatment physiological reactivity in treatment outcome and follow-up status was examined and revealed no significant associations. Synchrony-desynchrony patterns were found to vary widely according to both treatment phase and the time interval between assessments. No between-group differences were observed on the proportion of synchronizers. However, synchronizers exhibited superior outcome and follow-up compared to desynchronizers on all domains except the physiological measures. Conceptual, methodological and clinical implications of these findings are discussed with recommendations for future research. 相似文献

The purpose of this study was to assess retrieval strategy in incidental, intentional, and inclusion tests with word-fragment cues following a levels-of-processing manipulation at study. The results of Exp. 1 showed small levels-of-processing effects in incidental tests, and most subjects reported involuntary rather than voluntary retrieval of study-list words. In an intentional test, although levels of processing had a much greater effect, quite a few subjects also reported involuntary rather than voluntary retrieval of study-list words, and these subjects showed a smaller effect of levels of processing than subjects reporting voluntary retrieval. These results suggest that subjects given instructions for both voluntary and involuntary retrieval of study-list words in an inclusion test might not in fact attempt voluntary retrieval at all, but simply adopt an involuntary retrieval strategy. The results of Exp. 2 provided evidence to support this suggestion. The general implication is that where test contamination refers to subjects' failure to use retrieval strategies in accordance with test instructions, inclusion tests can be contaminated, as well as incidental or intentional tests, and that it is always necessary to obtain converging evidence about the actual strategies subjects use. 相似文献

Immigration and remarriage are two stressful events that impact on family's functioning and well being. This article examines the effects on families of experiencing both of these transitions simultaneously. A case illustration is presented and implications for practice and for future research are discussed. The article is based on the clinical experience of the writer as well as on her study of stepfamilies from diverse cultural backgrounds. 相似文献

Conclusion This paper gives a central place to that systemic process within dynamic psychotherapy that is called feedback. I have given
the historical antecedents of the multileveled, mutually influencing processes in feedback in terms of their evolution from
cybernetics, information, and system theories. Major interdisciplinary contributors included Norbert Wiener, John von Neumann,
Jurgen Ruesch, Warren Mc Culloch, Gregory Bateson, Margaret Mead, Kurt Lewin, and Lawrence S. Kubie, who came from such fields
as mathematics, neurophysiology, psychiatry, anthropology, psychology, ecology, and psychoanalysis. The place of free-associations,
the domain of intrapsychic and interpersonal feedback, the requirements for a matrix allowing for nurturing, curative interaction,
the nature of interventions, and the significance of transference-countertransference and reality in the feedback that occurs
in dynamic psychotherapy have been focused on in this initial presentation on the subject.

Recent work has sought to use the time at which the Lateralized Readiness Potential (LRP) first develops (LRP onset) as a temporal landmark to bisect experimental effects on reaction time (RT). Many studies have found experimental effects on the time between the signal and LRP onset, but few have found effects on the time between LRP onset and RT (LRP-RT interval). The primary goal of this study was to produce an effect on the LRP-RT interval. We employed precuing, a manipulation likely to influence motor-programming processes at the end of the RT interval. Subjects performed a 4-alternative choice-RT task in which a signal prompted a button-press with the index or middle finger on the left or right hand. Precues preceded the signals and were either informative, reducing the set of response alternatives from four to two, or uninformative. Besides RT and LRP, we also measured electromyographic (EMG) activity and the P300 ERP component. RT, P300 latency, and the interval between the signal and LRP onset were all shorter with informative than uninformative precues, but the timing of EMG activity relative to RT remained the same. Most importantly, precuing affected the LRP-RT interval. Implications for bisecting RT with LRPs and the identity of processes affected by precuing are discussed. 相似文献
