The influence of task difficulty on aberrant behavior was investigated with three severely handicapped students. Noticeably higher rates of problem behavior occurred in demand compared to no-demand conditions. In addition, there were higher rates of problem behaviors on difficult versus easy tasks. Both these findings were validated with visual discrimination and perceptual motor tasks. An errorless learning procedure effectively minimized errors and aberrant behavior in visual discrimination tasks but not in perceptual motor tasks. It was conceptualized that aberrant behavior was maintained by negative reinforcement contingencies. Difficult tasks were aversive to the children, who emitted aberrant responses to escape or avoid such tasks. By contrast, conditions in which no demands were made, easy tasks, and, in visual discrimination learning, errorless tasks, were less aversive and resulted in little or no problem behavior. Implications for reducing maladaptive behaviors through curricular modifications are discussed and contrasted to more traditional consequence manipulation approaches. 相似文献

Some psychologists involved in the implementation of applied behavioral psychology in educational systems must increasingly attend to the ecological impact of such interventions. An ecological orientation emphasizing system-like interdependencies among environment, organism, and behavior suggests several substantial additions to conventional role functions of behavioral school psychologists. Such functions involve taking an active part in evaluating and assessing second-order consequences of behavioral interventions. Recommendations for functional and procedural changes are provided within this framework. 相似文献

The nature of the difference in skill between the preferred and non-preferred hands was investigated using a peg-board task. The first experiment examined the effects of varying movement amplitude and target tolerance on performance. The difference between hands was found to be related to tolerance rather than movement amplitude. The second study analysed a film record of well-practised subjects, confirming the hypothesis that most of the difference between hands is due to relative slowness of the non-preferred hand in the positioning phase involving small corrective movements. Analysis of the type and number of errors further suggested that this result is not due to differences in duration of movements but to their increased frequency, implying greater accuracy of aiming with the preferred hand. Thus whilst the initial gross analysis implicated feedback processing in skill differences the more detailed analysis suggests that motor output of the nonpreferred hand is simply more variable. 相似文献

Three types of career counselling — Individual Career Counselling, the Vocational Exploration Group, and the Future Group — were compared to a placebo group and a no-treatment control group. All groups were evaluated in terms of changes in pre- and post-test scores on the Attitude scale of Crites' Career Maturity Inventory and on the ten scales of the Kuder Preference Record. The study showed the Future Group as compared to the no-treatment control to have a significant increase on the Musical Preference scale. The Future Group also had a significant increase on the Literary Preference scale as compared to the no-treatment control and individual counselling groups. The Future Group participants significantly increased in career maturity compared to participants from the no-treatment control and individual career counselling groups. The implications for career counselling as well as for additional research investigations are discussed. 相似文献

A potential mechanism that can explain preterm children's heightened risk for the development of later cognitive and behavioral problems is attention. Attention is the ability of an infant or child to orient to, to shift between and to maintain focus on events, objects, tasks, and problems in the external world, processes which are all dependent on the functioning of attentional networks in the brain. The aim of this paper is to provide a review of the literature on attention development in children born preterm during the first 4 years of life. First, research examining the differences between preterm and full-term children indicates that early attention development in infants born preterm is less optimal and that these differences increase when infants grow into toddlers. Second, studies investigating individual differences within preterm populations reveal the influence of both biological factors and environmental factors. Third, individual differences in early orienting and sustained attention have been shown to be predictive of later attentional, cognitive and behavioral functioning in children born preterm. The importance of long-term follow-up studies, with a focus on individual developmental trajectories in orienting, sustained and executive attention, is emphasized. 相似文献

International research has emphasised that empathy is a relevant factor of sex offending. The main goal of this study is to explore, in a Spanish sex offender sample, the relationship between empathy deficits and sex crime for various types of victims. This study also analyses the positive effect that psychological treatment could have on empathy. For this purpose, 118 non-sex offenders were compared on an adapted version of Rape Empathy Measure to 39 treated rapists and 34 untreated rapists. Results show that the untreated rapists have lower empathy levels than non-sex offenders. Nevertheless, the treated rapists scored higher on empathy than the other two groups assessed, untreated rapists and non-sex offenders. Lastly, some suggestions are provided for future research in terms of the assessment of empathy and other factors related to sexual aggression. 相似文献
