A total of 130 female undergraduates performed a counter-conditioning choice-task. This task presented two response alternatives and subjects were instructed to earn the maximum number of points. Responses to button 1 were normally followed by an immediate reward (an average gain of 7.5 points). Responses to button 2 were always followed by a punishment (an average loss of 20 points), but caused the next-but-one press on button 1 to give an average gain of 115 points. Thus, subjects were required to learn and maintain this counter-conditioning association. Four groups of subjects were formed according to the scores on the Sensitivity to Punishment and Sensitivity to Reward scales (which are measures of individual differences of Gray's anxiety and impulsivity personality dimensions, respectively). A 69.2% of subjects learned and maintained the counter-conditioning association. As predicted, personality results confirmed that subjects with lower scores on the Sensitivity to Punishment scale learned the counter-conditioning association better and faster when compared with high scorers. Results are consistent with Gray's Behavioral Inhibition System (BIS) model of anxiety which holds that individual differences in anxiety may relate to the ability to associate aversive stimuli with a future reward. Assuming that anxiety depends on BIS functioning, our results show that high trait anxious subjects, if compared with low anxious ones, would have a lower ability for associating an aversive event with a later appetitive one. This learning process would serve non-anxious subjects to reduce the aversiveness of cues of punishment and to cope better with stressful situations. 相似文献

Two nested structural models were developed to determine whether test-session behaviors affect the manner in which intelligence is measured or whether their influence is related to the constructs being measured. Children’s test-session behaviors were assessed using the Guide to the Assessment of Test-Session Behaviors for the WISC-III and WIAT (GATSB; Glutting & Oakland, 1993) and intelligence was measured with the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991). Model 1 investigated relationships between test-session behaviors and the WISC-III’s four-factor solution by first evaluating the underlying factor structure of the instruments. Thereafter, this measurement model served as a baseline against which alternative models were compared. The alternative models considered the influence of test-session behaviors on: (a) the subtests used to measure the WISC-III’s constructs of intelligence, and (b) the actual constructs of intelligence. Model 2 explored similar relationships by considering only the WISC-III’s Verbal and Performance dimensions. Results indicate that test-session behaviors play a larger role influencing the mechanisms through which intelligence is measured than on the actual constructs of intelligence. Implications are discussed for clinical practice. 相似文献

Stimulus control, a behavioral technique designed to reduce sleep difficulties, has been demonstrated to be effective when compared with control procedures. These comparisons, mainly involving between-subjects analyses, have neglected the contribution of the stimulus control procedure to the production of clinically significant amelioration of sleep dysfunction. In contrast, the present within-subjects experiment was conducted to assess the capability of stimulus control to produce clinically relevant reductions in multiple measures of sleep disturbance. A comparison with the credible placebo procedure indicated that the stimulus control techniques reduced subjects' sleep onset latency to a mean latency below 30 min per week. Additionally, sedative-hypnotic usage was greatly reduced. 相似文献

Studies show that aphasic patients typically are grossly impaired in short-term memory performance. Since aphasics generally experience difficulty in word retrieval, it is conceivable that short-term memory loss is partially the result of verbal rehearsal deficiency which, in turn, is caused by the word retrieval problem. This paper reports an experiment in which five aphasic adults were nonverbally to recall individualized lists of pictures they could easily name and lists of pictures they could not name. Final items in the two lists were recalled with equal accuracy; this was expected in that the recency effect usually reflects sensory rather than verbal storage. Initial items were recalled with greater accuracy than middle-list items in the nameable sets but not in the unnameable sets. This primacy effect suggests the aphasics rehearsed the nameable pictures, but both lists were recalled so poorly that rehearsal deficit was considered responsible for no more than a fraction of the aphasics' reduction in short-term memory. 相似文献

Both emotional and volitional systems are invoked in explaining the control of human vocalizations, but vocal behavior of nonhuman primates is often believed to be totally under emotional control. Monkeys' poor performance on conditioning tasks, especially discriminative conditioning of vocalization (DCV), has been cited as evidence against volitional control. In Experiment 1, rhesus monkeys failed a DCV task in which food was given for vocalizations emitted during an arbitrary visual stimulus, but in Experiment 2, monkeys showed clear discriminative performance when an otherwise comparable shock-avoidance DCV procedure was used. This evidence that monkeys possess some degree of volitional control has implications for the relation between animal vocalizations and the origin of human speech. 相似文献

This paper presents a very brief overview of people's attempt to understand and change behavior and shows how behavior analysis is different from these views. The importance of everyone knowing and using behavioral principles in their everyday life is stressed and the opposition to a behavioral approach is discussed. The aims of the organization called Behavior Analysis/Modification in the Regular Classroom is presented and some steps that this organization is following in an attempt to help to disseminate the knowledge and use of behavioral principles in the schools is presented. 相似文献

Infant attachment remains virtually unexplored in former Eastern Bloc countries. The dimensional approach to infant attachment, which could ease common obstacles in cross-cultural attachment research, necessitates more empirical support. This study explores infant attachment in the Czech Republic, a post-communist country with a unique family policy, using both the categorical and the dimensional models. It also compares the Czech infant attachment distribution to infant attachment distributions in other countries and compares infant attachment distributions in European countries to the Baltimore study sample. In the Strange Situation Procedure, forty-nine (74 %) out of sixty-six mother-infant dyads (35 boys, M = 13.8, SD = 0.9) received the B classification. Despite the generous family policy and cultural emphasis on close mother-infant relationships, the Czech distribution of insecure categories did not differ from the Baltimore study sample. Out of other post-communist countries, only the infant attachment distribution in former East Germany differed from the Czech and the Baltimore study samples due to a lower proportion of type B and a higher proportion of type A infants. There were also more type A infants in the Italian sample. Interactive behavior scales accurately predicted attachment categories in 91 % of cases. Contact-maintenance and proximity-seeking scales substantially improve the assessment of insecure resistant behavior. Our findings support the universality and normativity of attachment and the utility of the dimensional approach. 相似文献
