Forty-two children (ages 6 to 12 years old) with moderate mental retardation to borderline intellectual functioning were studied in a laboratory playroom setting to determine whether children identified as ADHD (attention deficit hyperactivity disorder) or controls differed on activity and attentional measures. Children with ADHD were further divided into ADHD + conduct problems (ADHD + CD) and ADHD-only subgroups (with an ADHD-combined group comprising children of both subgroups). An interval recording system was used to code observations of independent play and a restricted academic task. Results indicated that the ADHD-combined group was significantly more vocal and engaged in a significantly greater number of toy changes than controls during independent play. Significant group differences were also noted during the restricted academic task, with the ADHD-combined and ADHD + CD groups more off-task and engaging in a greater number of toy touches than controls. Discriminant analyses found independent play measures to predict group membership in 70 percent of cases (ADHD-combined vs. controls), but in only 64 percent of cases using measures from the restricted academic task. No significant findings resulted when the ADHD subjects were further divided into two subgroups. Despite some inconsistent findings, such laboratory-based observations may be of value in the diagnosis of ADHD in children with moderate mental retardation to borderline intellectual functioning.  相似文献

This study aimed to investigate the frequency andmeaning of the removal of body hair in women.Participants were 129 female university students (meanage = 22.3 years) and 137 female high school students (mean age = 14.3 years). Almost all (>95%)were Caucasian. It was found that, as predicted, the vastmajority (92%) of women remove their leg and/or underarmhair, most frequently by shaving. This was irrespective of their feminist beliefs, but wasnegatively related to self-esteem in university students.The reasons cited for hair removal were primarilyconcerned with a desire for femininity andattractiveness. However, the reasons provided for starting toremove body hair differed between the groups, in thatthey were relatively more normative for the universitystudents than for the high school students. It was concluded that women's stated reasons forstarting the practice of hair removal reflectprimarilytheir vantage point as an observer. In fact, removingbody hair is a practice so normative as to go mostly unremarked, but one which contributessubstantially to the notion that womens' bodies areunacceptable as they are.  相似文献

The present study investigated the impact of social reactions of others to sexual-assault victims on disclosure of their victimization. A convenience sample of adult sexual-assault victims (N = 155) completed a mail survey in which they reported information about their sexual assaults and postassault experiences. As expected, all negative social reactions were strongly associated with increased psychological symptoms, whereas most positive social reactions were unrelated to adjustment. The only social reactions related to better adjustment were being believed and being listened to by others. Victims experiencing negative social reactions also reported poorer adjustment even when other variables known to affect psychological recovery were controlled. Avoidance coping mediated the association of negative social reactions with adjustment. Implications of these findings for research and treatment of sexual-assault survivors are discussed.  相似文献

A semantic differential study of development of antonym meanings revealed methodological problems (e.g., concept-scale interaction and developmental changes in scale-checking style) not fully considered in previous semantic differential investigations of child language development. Twenty adjectives were rated on 10 scales by subjects from grades K to 5 (approximately 6 through 11 years old) and adults. Analyses by means, polarity ratings, and average sums of squared differences failed to yield consistent developmental trends. Subjects' choices of scale ratings did show clear age-related differences: Grades K and 1 chose extreme ratings almost exclusively; grades 2 through 4 showed an increase in neutral choices and decreases in extreme ratings; grades 4 and 5 and adults chose extreme ratings least often, neutral choices most often, and more intermediate ratings than any younger subjects. Results show that scale choice is a crucial factor in designing semantic differential studies with children, there is a low correlation between mean scores and ratings given by individual children, and shifts in scale-checking style should be considered when interpreting apparent developmental changes in children's semantic differential ratings.  相似文献

A course on cotherapy for mental health practitioners is described. The authors strongly recommend that clinicians from all disciplines be taught and trained to do cotherapy, since it is a highly effective therapeutic modality in treating individuals, families and groups.  相似文献

Psychological investigations of the impact of personality on health behaviours have tended to emphasize fine distinctions among personality variables while failing to distinguish among different kinds of behaviours. For example, theoretical treatments of perceived personal control are quite sophisticated; in contrast, only one well-known analysis of health behaviours exists. We propose four categories of health-enhancing behaviours, which take into account contemporary views of the shift in health care from acute and physician-directed actions to long-term and patient-directed efforts. In addition, we suggest that perceived control (we emphasize locus of control because of its generality and parsimony) is an important predictor variable when combined with other factors common to current models of health behaviour.  相似文献

Three experiments examined the effects of complete removal of reinforcement and of the introduction of a novel stimulus on conditioned approach and withdrawal behavior exhibited by pigeons in an autoshaping paradigm. Experiment 1 indicated that complete omission of food from the experimental situation resulted in the gradual disappearance of both approach and withdrawal behavior in subjects that had received either explicitly paired or explicitly unpaired conditioning. Subsequent presentation of a novel visual stimulus reinstated both approach and withdrawal. Experiment 2 replicated these findings in a within-subjects, discriminative paradigm. In Experiment 3, presenting the novel visual stimulus during acquisition when approach and withdrawal behaviors were asymptotic did not produce significant disruption of performance. These data suggest that removal of reinforcement leads to the disappearance of withdrawal as well as approach performance, and that subsequent presentation of a novel stimulys reinstates whatever behavior was dominant prior to extinction—a finding that seems analogous to results of experiments concerning proactive interference.  相似文献
