Four normal and four deviant children aged four-to-six years were taught to judge the quality of their academic work in a preschool classroom, and to prompt or cue their teachers to comment about the quality of that work. When these skills did not generalize spontaneously to other teachers in concurrent natural situations, generalized responding was taught by the experimenter, in multiple-baseline design across subjects. This generalization programming enabled the children to contact a sometimes dormant, but readily available natural community of teacher praise and reinforcement, i.e., to recruit an increase in cued praise and schedules of praise for their good work. These behaviors may be important to young children who find themselves bereft of attention in classrooms.  相似文献

Attentional biases for threat were examined in a non-clinical sample (N=60), with each participant tested on both the modified Stroop colour-naming and dot probe tasks. Three groups were selected on the basis of trait anxiety and social desirability scale (SDS) scores: “low anxiety” (LA: low trait, low SDS), “repressor” (REP: low trait, high SDS) and “high anxiety” (HA: high trait, low SDS). Results from the colour-naming task suggested that high levels of defensiveness (in combination with low trait anxiety) were associated with greater avoidance of threat. The REP group showed less interference in colour-naming threat than neutral words; whereas the HA group showed increased interference due to threat words. On the dot probe task, there was a general tendency for this non-clinical sample as a whole to show avoidance of social threat relative to neutral words, but there was no bias for physical threat words. Avoidance of social threat was significant only within the REP group. No relationships were found between the measures of cognitive bias from the two tasks, suggesting different underlying mechanisms. Results are discussed in relation to previous findings and theoretical views of the effects of anxiety and defensiveness on the processing of threat.  相似文献

Agrammatic aphasia is characterized by severely reduced grammatical structure in spoken and written language, often accompanied by apparent insensitivity to grammatical structure in comprehension. Does agrammatism represent loss of linguistic competence or rather performance factors such as memory or resource limitations? A considerable body of evidence supports the latter hypothesis in the domain of comprehension. Here we present the first strong evidence for the performance hypothesis in the domain of production: an augmentative communication system that markedly increases the grammatical structure of agrammatic speech while providing no linguistic information, functioning merely to reduce on-line processing demands.

Still and MacMillan (1977) suggested the negative of the Phi coefficient (- φ) as a measure of free-trial spontaneous alternation. This new index is compared with the Adjusted Alternation Ratio (AAR), previously developed by Manning (1973b). It is concluded that there are many situations in which the AAR is a more useful measure. Other issues in assessing spontaneous alternation noted by Still and MacMillan are discussed.  相似文献

In the current study, two mediational mechanisms, parenting practices and children's beliefs about aggression, were hypothesized to account for the relationship between perceived neighborhood danger and childhood aggression. Using structural equation modeling, data were analyzed from an inner-city school-based sample of 732 predominantly African American 5th graders. Results suggested that perceived neighborhood danger was associated with strong positive beliefs about aggression, which in turn was associated with high levels of aggression. The hypothesized mediating role of parenting practices (restrictive discipline, parental monitoring, and parental involvement) on the relation between perceived neighborhood danger and child aggression was not supported. However, the current findings suggest that children's positive beliefs about aggression mediated the relationship between restrictive discipline and aggression. Directions for future research are discussed.  相似文献

Changes in locus of control and self-esteem during social skills training and at 6 month follow-up were investigated. Forty-four adolescent, male offenders were randomly assigned to a social skills training, attention-placebo, or no-treatment control procedure. The results showed that pre- to post-training increases in self-esteem were produced for both the social skills training and attention-placebo control groups, but not for the no-treatment control group. These increases did not continue during the follow-up phase; the social skills training group, which showed the greatest improvement during training, displayed a decrease in self- esteem during follow-up.The locus of control measures showed a statistically significant shift towards internality for the social skills training group during training, which was not found for the attention-placebo and no-treatment controls. During the follow-up phase, all three groups showed a statistically significant shift towards externality, suggesting a tendency for boys to view their behaviour and consequences as being under the control of chance factors or powerful others, during institutionalization. This effect was partly reversed during training for the social skills training group, but the effect was not long lasting. It seems therefore that social skills training is effective in producing an increase in self-esteem and a shift towards internal locus of control. These changes are, however, of short duration and the self-esteem shift may be the result of increased staff contact or other non-specific therapy factors.  相似文献

In order to determine what variables contribute to or detract from the inter- personal attraction of a successful career woman, 80 male and 80 female introductory psychology students at a large western state university viewed one of eight different videotapes of a female stimulus person discussing aspects of her career and homelife. Two levels of occupation (traditional vs. nontraditional), two levels of competcnce (high vs. low), and two levels of role overload (high vs. low) were factorially varied for each videotape. The Attitudes toward Women Scale (AWS) was used as a covariate, thereby equalizing attitudes between the sexes. A multivariate analysis of covariance was performed on the data. Results indicated that all main effects-competence, role overload, occupation, and sex of subjects-were significant. Also significant was a sex of subject by occupation interaction and two three-way interactions. These results were discussed in the context of how they increase our understanding of college students' perceptions of successful career women.  相似文献

Bornstein and Quevillon (1976) demonstrated generalization from a 2-hour self-instructional training session to on-task behavior in the classroom with 4-year-old overactive children. In an attempt to replicate this work with older children, eight 7- and 8-year-old hyperactive children were assigned to either a self-instructional training group or an attention-practice control group. On-task behavior in the classroom and performance measures in reading and arithmetic were assessed. The level of difficulty of these tasks was varied. The results of Bornstein and Quevillon's (1976) study were not replicated, although the subsequent introduction of a token program significantly increased on-task behavior.  相似文献

The emphasis of much of the existing research on social support-health relationships has been on the availability and impact of support on the recipient, but social psychologists have paid little attention to the costs to the caregiver of providing that support. In an earlier study (Schulz & Decker, 1985), we found that the long-term coping of individuals experiencing chronic disability as a result of spinal-cord injury was facilitated by the availability of a primary support person, or caregiver. In this study we examined the determinants of well-being of the primary caregiver of the middle-aged and elderly spinal-cord-injured persons. Psychological well-being, life satisfaction, and depression were the dependent measures. The availability of social support, social contact, and feelings of control over one's life were important determinants of caregiver well-being, even after controlling for health and income. In addition, the amount of time spent each day assisting the disabled person was a strong independent correlate of depression, and the extent to which the caregiver felt burdened by the victim was significantly and negatively related to life satisfaction. These results are discussed in the context of a comprehensive stress-coping model. Since data were available from both disabled individuals and their primary support persons, we had the unique opportunity to compare the perspectives of both those giving and receiving daily care. We found no relationship in levels of psychological well-being and depression reported by the disabled person and caregiver; however, caregivers attributed to the victims affective levels similar to their own.  相似文献
