The influence of teacher expectations on student achievement in physical education classes: Pygmalion revisited

The main purpose of this study was to explore the relation between teacher expectations and student achievement in physical education classes, in the light of three complementary hypotheses. Student achievement may confirm teacher expectations because these expectations create self‐fulfilling prophecies, create perceptual biases, or accurately predict, without influencing, student achievement (Jussim, 1989 ). Another purpose was to examine the mediating role played by students' perceived ability in the teacher expectancy process. Study data were obtained from 173 students and 7 teachers. Path analysis revealed that teacher expectations have weak self‐fulfilling effects, strongly predicted student achievement mainly because they are accurate, and have no biasing effects on teacher judgements. Results also show evidence concerning the role of partial mediator of perceived student ability in the confirmation process of teacher expectations. Copyright © 2002 John Wiley & Sons, Ltd.     

The Integration of Family and Group Therapy as an Alternative to Juvenile Incarceration: A Quasi‐Experimental Evaluation Using Parenting with Love and Limits

The current study employed a quasi‐experimental design using both intent‐to‐treat and protocol adherence analysis of 155 moderate‐ to high‐risk juvenile offenders to evaluate the effectiveness of Parenting with Love and Limits® (PLL), an integrative group and family therapy approach. Youth completing PLL had significantly lower rates of recidivism than the comparison group. Parents also reported statistically significant improvements in youth behavior. Lengths of service were also significantly shorter for the treatment sample than the matched comparison group by an average of 4 months. This study contributes to the literature by suggesting that intensive community‐based combined family and group treatment is effective in curbing recidivism among high‐risk juveniles.     

A Qualitative Investigation of Women's and Men's Body Image Concerns and Their Attitudes Toward Aging

In-depth interviews were conducted with 42 women and men (aged 22–62 years) to explore their relationships with their bodies. The particular focus was age-related changes in body image and attitudes toward the body aging, an area that has received little research attention to date. Thematic analysis revealed distinctive gender differences. Men commonly conceptualized their bodies as a holistic entity, whereas women commonly had compartmentalized conceptualizations. They also construed the importance of their bodies differently: men tended to focus on functionality, and women tended to focus on display. These findings may help to explain gendered consequences of body dissatisfaction. Accounts about the aging of the body support a “double standard of aging.” Women viewed aging most negatively in terms of its impact on appearance, whereas men reported a neutral or even positive impact on appearance.     

Sex role stereotyping in Australian television advertisements

Television has attracted considerable attention in recent years because of alleged bias in its sex-role content. Studies of television in Great Britain and the United States have generally fuelled concerns that the medium presents male and female characters in traditionally stereotyped ways. Comparatively little research has focused on the way men and women are depicted in other nations' television. Such analyses contribute towards a more comprehensive account of sex role stereotyping and to cross cultural investigation. The present study examined the portrayal of male and female characters in a sample of contemporary Australian television advertisements. A sample of evening commercials was analyzed using measures developed in North American and British work. Strong evidence of differences in the presentation of male and female characters was obtained, and the differences were consistent with those reported in studies of television content in the northern hemisphere. There is little reason to suppose that this area of Australian media is changing substantially in response to public debate. The implications of possible differences between nations in terms of sex role stereotyping in commercials are discussed.     

Atypical development of language and social communication in toddlers with Williams syndrome

Williams syndrome (WS) is a genetic disorder which results in an uneven cognitive profile. Despite superior language compared to other syndromes in the phenotypic outcome, toddlers with WS are as delayed in their language onset and early linguistic development as are toddlers with other syndromes. The cause of this delay in WS is as yet unknown. In a series of experiments, we examined whether atypical socio‐interactive precursors to language could contribute to the explanation of the late language onset and atypical developmental pathways observed in WS. Experiment 1 showed that despite superficially good social skills, toddlers with WS were only proficient at dyadic interaction. They were impaired in triadic interaction, essential for the referential uses of language, and showed none of the correlations between socio‐interactive markers and language seen in the typical controls. Experiment 2 focused on the comprehension and production of referential pointing. Again, the WS group was impaired, despite vocabulary levels higher than those of typically developing controls. Finally, Experiment 3 examined fine motor skills. The WS lack of pointing could not be explained in terms of motor impairments, since the WS toddlers were proficient at fine motor control, such as the pincer grip. Overall, our data indicate that the early stages of WS language follow an atypical pathway. The findings challenge the frequent claims in the literature that individuals with Williams syndrome have preserved linguistic and social skills.     

The behavioural treatment of sleep difficulties in children with an intellectual disability

Reinforcement, instruction giving, partner support strategies, bedtime routine, and standard extinction were taught to the parents of three boys (aged 5–10 years) with an intellectual disability and sleeping difficulties. Sleep was measured using sleep diaries and actigraphy, and daytime behaviour was monitored using diaries and direct observation. At referral, all children needed a parent present to fall asleep, two had co‐sleeping difficulties, and two had night waking difficulties. At post‐intervention, all children were falling asleep independently, co‐sleeping was eliminated for two children, and night waking was reduced in one child. An extinction burst was experienced by two children, with one family putting their child back to bed 259 times on the first night. Though one child still had night waking difficulties following intervention, actigraph recording demonstrated an improvement in his sleep quality. In addition to the children's independence, improvements were seen for sleep length, sleep latency, and morning wake time. However, improvements in daytime behaviour showed inconsistency across behaviours and settings. Improvement in sleep was maintained at a three month follow‐up. It was concluded that using extinction to address sleep problems in children with an intellectual disability is effective and approved of by parents, but any impact on daytime behaviour is equivocal.

Relationship between bullying and scores on the Buss‐Perry Aggression Questionnaire among imprisoned male offenders

This study investigated the relationship between bullying and aggression among imprisoned male adult offenders. The participants were 70 imprisoned male offenders, who were classified using the Direct and Indirect Prisoner Behaviour Checklist (DIPC) as one of four ‘bully’ groups: pure bully, pure victim, bully/victim, or not involved. Participants also completed the Buss‐Perry Aggression Questionnaire (AQ), a measure of aggression and hostility. The majority of the prisoners reported behaviors indicative of bullying, with 42.9 percent classified in the bully/victim group and 12.9 percent as pure bullies. 15.7 percent of participants were classified as pure victims, while 28.6 percent did not report any involvement in bullying. Bully/victims scored higher than participants who were not involved in bullying on the Hostility scale and Total score of the AQ. A number of correlations were found between the AQ scores and number of bully behaviors perpetrated. These suggested there is an overlap between the constructs measured by the AQ and type of bullying behaviors perpetrated. The number of bullying behaviors experienced was only correlated with the Hostility scale. The results are discussed in terms of previous research and their implications for theory and practice.
