The aim of the study was to investigate impulse control in children with conduct disorder (CD) plus borderline intellectual functioning (BIF), in children with BIF-only, and in a control group with a normal IQ. For this purpose, a Go-No-Go test with varying inter-stimulus-intervals was used. The group CD plus BIF made more errors of commission than the group with BIF only. Therefore, it was concluded that poor impulse control in the group CD plus BIF was associated with CD, not with IQ level. Poor impulse control in the group CD plus BIF was independent of the presentation rate of the stimuli. 相似文献

Summary Within contemporary visual-information-processing psychology, two classes of selective-attention theories can be distinguished: position-not-special theories and position-special theories. The position-not-special theories postulate that attentional selection by colour, by form, and by position are equivalent selective operations. The position-special theories assume that selection by position is more basic or direct than selection by colour or by form. Examples of both types of theory are briefly described, and irrelevant and relevant evidence is critically discussed. It is concluded that the relevant evidence is directly compatible with the position-special views and that the position-not-special theories require additional extraneous assumptions. The position-special model presented in Van der Heijden (1992) is elaborated in further detail. It is shown that this model is compatible with two important and often substantiated assumptions of the position-not-special theories: the assumption that pre-attentive analysers organize the visual scene in objects against a background, and the assumption that visual-selective attention can be directed at objects isolated in this way. This position-special theory is a parsimonious theory because it can identify the mentalistic conceptselective attention with the materialistic conceptspatial position. 相似文献

The effects of lactate infusion on subjective mood change were studied in two differently instructed groups, in a double-blind, placebo-controlled, cross-over study. Ss who were told that infusions would produce anxiety reported a significant change in the expected direction after lactate but not after glucose. Ss who were told that infusions would produce a state of pleasant excitement showed no change after either infusion. The possible role of cognitive parameters in experimentally-induced anxiety is discussed. 相似文献

The present study investigated the effectiveness of a social skills training program with 131 socially-anxious psychiatric inpatients and outpatients. Ninety-six patients were admitted to the treatment condition: 20 of them dropped out during treatment; 35 patients were randomly assigned to the control group. The social skills training resulted in a decrease in social anxiety and an increase in social skills. Treatment effects were maintained 3 months after treatment. Predictors of treatment outcome immediately after treatment and after a 3-month period of follow-up were investigated. The results are discussed with reference to extending the treatment targets to include a more active expansion of real-life situations and to the implementation of the therapy program in a clinical setting. 相似文献

Although some research suggests that misinformation provided by a co-witness could be more influential than that obtained from other sources, most of this research has compared the effect of co-witness information against non-social forms of misinformation only. To better understand the influence of co-witnesses we compared the influence of co-witness misinformation with the influence of misinformation provided by an interviewer. Across two experiments using the MORI paradigm we found no evidence that a co-witness is particularly influential relative to another social source of post-event misinformation. In fact, the source of the misinformation delivered by our interviewer was less likely to be correctly recalled than the source of the misinformation delivered by a co-witness. There was some evidence that misinformation delivered by both a co-witness and an interviewer has a stronger effect on witnesses' accuracy and confidence than misinformation obtained from either source alone. Finally, our results suggest that the opportunity to provide an early individual memory account might protect against the effect of subsequently-encountered co-witness misinformation. These results have important implications for the way that criminal investigations are conducted. 相似文献

ABSTRACT. The authors’ aim was to investigate the speed-accuracy tradeoff in soccer kicking with the dominant and nondominant foot by using different types of instructions prioritizing speed or accuracy in experienced soccer players. Ten male soccer players were randomly given 1 of the 4 instructions that differed in aspects of the kick they should emphasize and what the secondary aim would be (speed or accuracy). It was found that ball velocity was affected by instruction in the expected way: emphasis on accuracy and ball velocity reduced for both kicking feet. In addition kicking accuracy increased when emphasizing this, but only with the dominant foot indicating that Fitts’ law only was found in kicks with the dominant foot. 相似文献

Abstract In the present study, effects of a health education (INFO) and a PsychoEducational Prevention (INFO + PEP) Programme were Investigated in three hospitals. These programmes were offered to groups of coronary heart disease (CHD) patients and their partners alter discharge from hospital. The INFO was offered to 127 CHD patients in addition to FIT (i.e. standard medical care and physical training). The PEP was offered to 90 Patients in, addition to the INFO and FIT. A control group of 122 patients received only FIT. The INFO and the PEP consisted of four weekly two-hour group sessions each. In addition, the PEP was followed by seven telephone follow-up contacts. On average, patients improved their lifestyles during the first three months. Between three and twelve months an extra improvement was found for eating habits, whereas there was a relapse for smoking and a sedentary lifestyle. In the short term, angina pectoris and a longer period of heart complaints were parallelled with a decrease in the risk of maintaining unhealthy eating habits, whereas in the long term a longer period of heart complaints a younger age and unemployment predicted a lower risk of maintaining unhealthy eating habits In the short term living with a partner and in the long term female gender were predictive of continued smoking behaviour In the short term, older age, a first CABG and a specific hospital setting decreased the risk of a continued sedentary lifestyle. The FIT + INFO + PEP had a favourable short-term effect on eating habits. For smoking and a sedentary lifestyle, however, there were negative effects. In the short term patients in the FIT +INFO and those in the FIT +INFO+PEP had significantly more problems in quitting a sedentary lifestyle than those in the FIT intervention in the long term, patients in the FIT + INFO had significantly more problems in stopping smoking compared to these in the FIT. 相似文献

The present study addresses the applicability of the Transtheoretical Model's processes of change in explaining adolescents’ readiness to quit smoking. Furthermore, the association between nicotine dependence and readiness to quit was assessed both directly, as well as indirectly through the processes of change. A cross-sectional survey was conducted, identifying 1547 weekly smokers aged 14–18 years. Structural equation modelling showed that the processes of change were only marginally associated with readiness to quit. Adding nicotine dependence to the model showed a direct association between nicotine dependence and readiness to quit. Only one process of change, self-liberation (i.e. choice/commitment to change and belief in the ability to change), was found to mediate this association. Nicotine dependence appeared to be highly important in adolescents’ readiness to quit. 相似文献

The present study tested whether baseline perceived social support and social integration predicted baseline and follow-up measures of health-related quality of life for 364 older adults with osteoarthritis. The findings are secondary analyses of a randomized controlled trial of an exercise intervention. Multiple regression analyses indicate that perceived social support was related to baseline measures of functioning in psychological (depressive symptoms, social functioning, and life satisfaction) and physical domains (self-rated disability, observed physical function, and perceived health), after accounting for demographic and clinical status factors. At 18-month follow-up (additionally controlling for exercise intervention and baseline outcomes), social support significantly predicted changes in psychosocial functioning, but was unrelated to changes in self-reported and observed physical health. The findings indicate that social support is an important predictor of long-term psychosocial outcomes, but is less important than baseline clinical status for physical health endpoints in this cohort of older adults. In contrast, social integration was not a consistent predictor of outcomes. 相似文献
