Well-trained classically conditioned stimuli, presented unreinforced, were protected from extinction when they were followed by a signal of the omission of the reinforcer (conditioned inhibitor Konorskian type) in eight cats. An aversive classical conditioning paradigm with shock as the reinforcer was used. Of several behavioral (leg flexion, vocalization) and organismic arousal (heart rate, respiration rate, respiration amplitude) measures of conditioned responses, the respiration amplitude changes were found to be most informative for the continuous assessment of elicited arousal of low and medium intensity. In all subjects conditioned stimuli presented during extinction in serial compound with the conditioned inhibitor elicited larger responses than did conditioned stimuli presented alone during extinction. The mechanism of protection from extinction in a paradigm in which the elicitor of learned behavior occurs prior to the conditioned inhibitor provides the organism with the mechanism for the maintenance of learned behavior in the absence of a reinforcer. 相似文献

An apparatus for aversive conditioning of adult cats and kittens is described. Animals are held by a cloth harness and head restraint device in a metal frame with a movable treadmill floor. They are supported in a natural standing position, with freedom to flex and move each leg and to walk or run on the treadmill. Various transducers record respiration, EKG, vocalization, leg flexion, and locomotion on the treadmill. 相似文献

In an attempt to examine the unconscious roots of values, this paper explores Gotthard Booth's psychosomatic theory that disease is a message of the whole person. It outlines his work in describing distinctive personality types who characteristically become ill through the disease of the organ system that is dominant for their life-style. The disease represents accommodation in the person's object relatedness and as such reflects the operation of unconscious values and indicates possibilities for therapy. Because the cultural environment helps condition the dominant organ response, Booth's work also has relevance for developing a sociology of value and suggests a prophylactic role for religion. 相似文献

Social science research and theory about familial orientations and reproductive ideals have largely neglected males' attitudes. Drawing on demographic and status attainment perspectives, this study applies a model of processes underlying marriage and family timing to longitudinal data on 288 young adult males from the Southern Youth Study. Several posited influences of family of origin factors, significant others, and adolescent status and familial aspirations on marital timing and early family growth are assessed.Development of this report was sponsored in part by the Texas Agricultural Experiment Station and contributes both to TAES Project H-2811 and to USDA (CSRS) Regional Research Project S-81, and in part by the Maxwell Policy Center on Aging and the All-University Gerontology Center, Syracuse University through Title IV-C Grant #90-A-1054101 from the Administration on Aging, Department of Health, Education, and Welfare. Information for analysis was obtained by pooling data collected under grants provided by the Agricultural Experiment Stations of Alabama, Georgia, South Carolina, and Texas. Appreciation is expressed to John Womack, Paul D. Mader, and G. David Curry for their advice at various stages of this research. 相似文献

Comparisons are made between self-identified feminists and traditionalists on an attitudinal inventory scale. Feminists are found to display a more consistent sex-role ideology as measured by inter-item consistency. Traditionalists believe in labor and political equality, but differ from feminists in regard to relations with men and notions of domestic roles. The findings suggest that a more consistent sex-role ideology among women should occur with increased feminist identification. However, stereotypes and misunderstandings concerning feminism may prevent this development among many women.This article is a revised version of a paper presented at the Alpha Kappa Delta Research Symposium, Richmond, Virginia, February 1978. 相似文献

Inversion and photographic negation both impair face recognition. Inversion seems to disrupt processing of the spatial relationship between facial features ('relational' processing) which normally occurs with upright faces and which facilitates their recognition. It remains unclear why negation affects recognition. To find out if negation impairs relational processing, we investigated whether negative faces are subject to the 'chimeric-face effect'. Recognition of the top half of a composite face (constructed from top and bottom halves of different faces) is difficult when the face is upright, but not when it is inverted. To perform this task successfully, the bottom half of the face has to be disregarded, but the relational processing which normally occurs with upright faces makes this difficult. Inversion reduces relational processing and thus facilitates performance on this particular task. In our experiments, subjects saw pairs of chimeric faces and had to decide whether or not the top halves were identical. On half the trials the two chimeras had identical tops; on the remaining trials the top halves were different. (The bottom halves were always different.) All permutations of orientation (upright or inverted) and luminance (normal or negative) were used. In experiment 1, each pair of 'identical' top halves were the same in all respects. Experiment 2 used differently oriented views of the same person, to preclude matches being based on incidental features of the images rather than the faces displayed within them. In both experiments, similar chimeric-face effects were obtained with both positive and negative faces, implying that negative faces evoke some form of relational processing. It is argued that there may be more than one kind of relational processing involved in face recognition: the 'chimeric-face effect' may reflect an initial 'holistic' processing which binds facial features into a 'Gestalt', rather than being a demonstration of the configurational processing involved in individual recognition. 相似文献

Research which has related scores on the Children's Depression Inventory (CDI) to suicidality have generally neglected to examine the possibility that specific depressive factors within the CDI may be more predictive of suicidality than the full scale score. Knowledge of such factors would help to explain the relationship between depression and suicidality and improve the prediction of suicidal behavior. The current study examined the relationship of depressive factors to suicidality in a sample of 200 incarcerated juvenile delinquents. The published factor structure for the CDI and one derived from the delinquent population were compared. Results revealed two factors from the derived solution, hopelessness and low self-esteem, to be more powerful predictors of suicidal ideation than the full-scale CDI score. These results suggest that symptoms such as low self-esteem and hopelessness may be responsible for the well-documented relationship between depression and suicidality. Furthermore, it appears that the prediction of suicidality may be improved by examining specific depressive factors in suicide research as opposed to full-scale scores from depression inventories such as the CDI. 相似文献
