In the current investigation, we used direct and indirect methods to assess and treat several topographies of aggression that were hypothesized to have separate operant functions in a young boy with severe mental retardation and pervasive developmental disorder. First, a functional analysis of aggression, using the methods described by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994), was conducted and produced inconclusive results. Next, indirect methods were used to develop a second functional analysis, which showed that chin grinding (firmly pressing and grinding his chin against the skin and bones of others) persisted independent of social contingencies and that the other topographies of aggression (e.g., hitting, kicking) were maintained by social positive reinforcement (attention). A treatment designed to decrease aggression maintained by attention—functional communication training with extinction—reduced all forms of aggression except chin grinding. This latter topography of aggression, which we hypothesized was maintained by automatic reinforcement, was reduced when the response-reinforcer relation was interrupted through response blocking and the child was provided with an alternative form of chin stimulation. 相似文献

Individuals engaged in a location task where the relevancy status [relevant (stimulus) vs irrelevant (distractor) information] of these locations was reversed from one trial (prime) to the next (probe). The results produced by these reversals (Distractor-to-Stimulus and Stimulus-to-Distractor) indicated that both stimulus and distractor items are given relevancy status labels which participate in the future processing at the labeled locations. These findings support the view that selective processing involves both ‘facilitatory' and ‘inhibitory' components. Further, unlike identity tasks, the data indicated that neither the formation nor the subsequent use of these ‘location' labels (stimulus or distractor) is related to the presence of a response conflict.PsycINFO classification: 2330; 2340 相似文献

Two studies evaluate the role of self-esteem in the depressive attributional style. In the first study, college students completed four measures of depression, four measures of self-esteem, and the Attributional Style Questionnaire (ASQ). Regression analyses revealed that across measures, self-esteem was a better predictor of attributional style for negative events than was depression. In study two, psychiatric inpatients completed a measure of self-esteem, a measure of depression, and the ASQ. In this clinical sample, self-esteem and depression were highly correlated and both predicted ASQ scores. But when variation in depth of depression and social desirability were removed statistically from the association between self-esteem and attributions for negative outcomes, there remained a significant association between self-esteem and internal, stable, and global attributions for negative outcomes. Controlling for the variation in self-esteem eliminated the relation between depression and depressive attributional style. These findings demonstrate the importance of self-esteem in depressive attributional style in both normal and clinical populations, as well as potential differences in the relations among self-esteem, depression, and attributional style in clinical versus normal samples. 相似文献

The Epicurean argument that death cannot be a misfortune for the person who dies because, when death occurs, there is no longer a person to whom any misfortune can befall, fails to establish the conclusions which its defenders have sought from it. Beginning with the premise that death can be bad, either for the victim or in quasi-impersonal terms, the author seeks to define that badness through philosophical analysis. The belief that to have more life than is worth living is always better than to have less is reconciled with the notion that the badness of death increases with the degree of psychological connectedness, using the examples of the deaths of an unborn fetus and of a 35-year-old woman. The author contends it can be better for a person to suffer a worse death at 35 than never to have lived at all. 相似文献

We conducted two experiments in which moderately mentally retarded persons were trained first to label and then to enter characters into a computer, calculator, or checkbook (label-then-do) within a multiple baseline design. In Experiment 1, 5 young adults were trained to enter statistical programs into computers in an office setting. Following training, all subjects' use of verbal labels and key-entry skills generalized across tasks (programs) and settings (offices and computer terminals). In Experiment 2, 3 junior high school students were trained with self-labeling procedures to complete a key-entry task and to balance a checkbook. The performance of all students generalized across tasks and settings, and the use of labels generalized for 2 of the students. Results are discussed relative to mediated generalization and to establishing verbal control over behavior. 相似文献

This study assessed the idea that theme park visits can influence cultural beliefs about the past and, further, that such effects depend on the schema of the park most available to the particular visitor. Subjects were randomly assigned to complete a questionnaire either before entering or after exiting Old Tucson, an Old West theme park and movie location. In addition, subjects were given either an “authentic Old West town” cue, a “famous movie location” cue, or no cue. It was expected that the cues would affect Old Tucson's impact on beliefs about the Old West. There was a significant entrance-exit by cue interaction for beliefs in the myth of the Old West. As expected, when no cue was provided, belief in the Old West myth was stronger for exit subjects than for entrance subjects. When the town cue was provided, belief in the myth of the Old West was not affected by the visit. When the movie cue was provided, belief in the Old West myth was weaker for exit subjects than for entrance subjects. For movie cue subjects, the Old Tucson experience seemed to debunk the myth. 相似文献

We investigated the factor structure of the Children's Sleep Behavior Scale in an unselected sample of children (N=838), ages 6 to 12.5 years, drawn from an elementary school population. Although no factor emerged that corresponded exactly to the parasomnias, as described by the Association of Sleep Disorders Centers (1979), all of the variables that loaded on Factor 1 were behaviors characteristic of the parasomnias, with the exception of recalled nightmares. Variables that were expected to load on this factor, but did not, were sleeptalking, teeth grinding, and enuresis. Enuresis was not related to any of the sleep behaviors assessed, and teeth grinding shared less than 9% of the variance with any of the other variables. Many of the variables loaded on more than one factor. The second factor, which was labeled bedtime resistance, was the only clearly unambiguous factor. Of the five factors that emerged, the third reflected positive affect, the fourth was a motor factor, and the fifth was an anxiety factor. Nightmares loaded on the anxiety factor as well as the first factor. The results of the study offered no support for the category of Disorders of Initiating and Maintaining sleep (DIMS), which has a childhood onset.This research was supported by a grant from the University of New Brunswick Research Fund. 相似文献

Perception of target displacement is severely degraded if the displacement occurs during a saccadic eye movement, but the variation of this effect across the visual field is unknown. A small target was displaced from a starting point at the midline, or 10 deg to the right or left, while the eye made a saccade from the 10 deg right position to the 10 deg left position. Saccades were detected and the target displaced on line. Assessed with a signal detection measure, suppression was stronger in central vision than in more peripheral locations for all three subjects. Leftward and rightward displacements yielded equal thresholds. The results complement the findings of others to reveal a picture of perceptual events during saccades, with both deeper saccadic suppression and faster correction of spatial values (the correspondences between retinal position and perceived egocentric direction), favouring more accurate spatial processing in central vision than in the periphery. 相似文献

An exploratory study of parent-child communication about sex and the sexual attitudes of early, middle, and late adolescents 总被引:1,自引:0,他引:1

In an attempt to examine the relationship between parent-child communication about sex and parent-adolescent attitudes about sex, 12- to 20-year-olds (N = 141) and their parents completed sexual communication and attitude questionnaires. The correlation between parents' and children's attitudes were high for all the early adolescents and low for all the middle adolescents. Only among the late adolescents was there a significant difference in the correlations between the sexual attitudes of parents and their children as a function of family communication level, with the attitudes of adolescents and parents in the high communication group being highly correlated and the attitudes of adolescents and parents in the low communication group not being significantly correlated. Middle adolescents had significantly more permissive sexual attitudes than early and late adolescents. Gender variables were also studied, but conclusions were limited due to the small number of participating fathers. All findings must be tempered with the recognition of the possible sampling bias introduced by the use of a convenience sample. It is suggested that the more responsible sexuality seen in adolescents who can talk to their parents about sex may be a function of the similarity in sexual attitudes between these late adolescents and their parents. 相似文献
