Some learners with multiple disabilities display idiosyncratic gestures that are interpreted as a means of making choices. In the present study, we assessed the validity of idiosyncratic choice-making behaviors of 3 children with multiple disabilities. Opportunities for each child to choose between food and drink were provided under two conditions. In one condition, the children were given the food or drink item corresponding to their prior choice. In the other condition, the teacher delivered the item opposite to that chosen. It was reasoned that valid choice-making behaviors would be reflected in a greater tendency to accept the chosen item and refuse the unchosen item. Direct observations revealed all children consistently indicated choices during both conditions. Choices of both the food and drink items were made by all 3 children. A reversal design demonstrated that acts of refusal were more frequent when choices were followed by delivery of the item opposite to that chosen. Similar assessment procedures may be effective in determining the function of idiosyncratic gestures exhibited by persons with multiple disabilities. For children lacking such skills, intervention to teach valid choice-making behaviors may be needed to complement assessment procedures. 相似文献

One of the most controversial, if not the most controversial, aspect of behaviorism is its claims (actual and putative) concerning cognition. Part of this controversy is caused by egregious exegetical errors on the part of Skinner's critics. Critics can then easily refute behaviorism by attributing these problematic claims to Skinner. This paper attempts to faithfully describe Skinner's claims regarding cognition. Skinner advances several arguments regarding the role of cognitions in human behavior and in the science of human behavior. We suggest that there are two distinct kinds of claims in this web: 1) claims regarding the proper relation between science and cognitions and 2) claims regarding the status of cognitions as natural events. Due to the multiplicity and interdependence of many of these arguments, it is best to view Skinner's position on cognition as consisting of a web of interdependent claims. 相似文献

The traditional male gender role has been associated with a host of psychological and physical problems. In this study, 118 male university students viewed one of two videotaped interventions based on R. E. Petty and J. T. Cacioppo's [(1986) Communication and Persuasion: Central and Peripheral Routes to Attitude Change, New York: Springer-Verlag) elaboration likelihood model of attitude change (ELM) or were in a control group. One intervention was designed to create less traditional male gender-role attitudes, the other to enhance participants' attitudes toward seeking psychological help. Both interventions significantly changed male gender-role attitudes on Brannon Masculinity Scale scores, but not their Gender Role Conflict Scale—I scores, and neither influenced help-seeking attitudes. The overall pattern of scores suggests that men's attitudes about the male role may be less resistant to change than attitudes about one's own gender role or one's fear of femininity. 相似文献

We conducted six experiments to determine if mental rotation can begin before perception finishes, as allowed by continuous flow models but not discrete stage models of information processing. The results of Experiments 1–3 showed that the effect of shape discriminability on RT was underadditive with the effect of stimulus orientation, suggesting that mental rotation began before shape discrimination had finished and that the two processes overlapped in time. The results of Experiments 4–6 indicated that mental rotation can overlap with color discriminations as well. In both sets of experiments, however, the amount of underadditivity tended to be much less than predicted by models allowing interference-free overlap. This suggests that mental rotation can overlap with perceptual analysis, contrary to fully discrete models, but that little rotation is carried out during this overlap due to interference between simultaneous discrimination and rotation processes. 相似文献

Investigated the potential role of state-dependent learning in cognitive therapy with spider phobics. It was hypothesized
that one strategy for increasing the effectiveness of cognitive therapy for anxiety would be to induce anxiety in subjects
while they were learning the cognitive restructuring principles (i.e., during treatment). Thirty-two undergraduate volunteers
were randomly assigned to one of six experimental conditions. Subjects in the five treatment conditions (the sixth was a no-treatment
control condition) met for three sessions of cognitive restructuring,in vivo exposure, or a facts lecture (i.e., the placebo group). Results indicated that when working with spider phobics, three sessions
of cognitive restructuring,in vivo exposure, or a facts lecture resulted in equal effectiveness immediately following treatment, but are more effective than
no-treatment at all. 相似文献

Two experiments were conducted to assess discrimination of picture requests for missing items among young children with developmental disabilities. In Experiment 1, three children were first taught to request one object when it was missing from a set of two related leisure items. In Experiment 2, two children were taught to request one object belonging to a set of three leisure items. In both studies the requesting response consisted of pointing to a photograph of the missing item. After acquisition of the initial request, discrimination of picture requests was assessed when the second item (Experiment 1) and second or third item (Experiment 2) was missing. Requests for the untrained items emerged in the presence of natural maintaining contingencies and in the absence of instructional prompts for all but the third child in Experiment 1. This child required continued intervention on the initial request. The results suggest that for some children a sequence of intervention and the programming of natural maintaining contingencies may prove effective in promoting the discrimination of picture requests for missing items among young children with developmental disabilities. 相似文献

An experiment was conducted to assess the effects of an ethnic slur on evaluations of a targeted minority group member by those who overheard the slur. White subjects plus four confederates participated in a study ostensibly concerned with debating skills. Two of the confederates, one of whom was black, were always picked to engage in a debate which the others were to evaluate. The black debator either won or lost the debate. After the debate, one confederate-evaluator criticized the black in a manner that either did or did not involve an ethnic slur; in a control condition, no such comment was made. Based on the notion that ethnic slurs activate negative schemata regarding members of the targeted minority group, it was predicted that when the black debator lost the debate, the ethnic slur would lead to lower evaluations of his skill. This hypothesis was supported. Theoretical and practical implications of the findings were discussed. 相似文献

Children's Representation and Imitation of Events: How Goal Organization Influences 3‐Year‐Old Children's Memory for Action Sequences 下载免费PDF全文
Children's imitation of adults plays a prominent role in human cognitive development. However, few studies have investigated how children represent the complex structure of observed actions which underlies their imitation. We integrate theories of action segmentation, memory, and imitation to investigate whether children's event representation is organized according to veridical serial order or a higher level goal structure. Children were randomly assigned to learn novel event sequences either through interactive hands‐on experience (Study 1) or via storybook (Study 2). Results demonstrate that children's representation of observed actions is organized according to higher level goals, even at the cost of representing the veridical temporal ordering of the sequence. We argue that prioritizing goal structure enhances event memory, and that this mental organization is a key mechanism of social‐cognitive development in real‐world, dynamic environments. It supports cultural learning and imitation in ecologically valid settings when social agents are multitasking and not demonstrating one isolated goal at a time. 相似文献
