Training divided attention and memory skills of older adults

The study examined whether divided attention and memory skills of older adults could be improved through video game training. The findings show that limited training with the games cannot enhance these skills. However, greater amounts of training could improve these vital skills amongst older adults.

Menopausal stage and age and perceptions of body image

The aim of This study was to investigate the association between menopausal stage and age and women's perception of their body image. Females from a community sample (n = 304. age range from 35 to 65 years) volunteered to complete a structured questionnaire which contained the Multidimensional Body Self Relations Questionnaire (MBSRQ) and the Stunkard Body Shape Figure Scale. One hundred and twenty women were premenopausal, 76 women were perimenopausal and 108 were postmenopausal. The effects of age and menopausal stage could not be separated in ratings of appearance evaluation, fitness evaluation, current, ideal and societal ratings of the Stunkard Body Shape Figure Scale. Premenopausal women (who were likely to be younger) had more positive ratings of appearance evaluation and fitness evaluation than menopausal women (who were likely to be older). Women who were premenopausal nominated smaller figures from the Stunkard Body Shape Figure Scale for ratings of the current, ideal and societal body shape than women who were perimenopausal and postmenopausal. The implications of these findings as they relate to women as they progress through the menopausal transition and as they become older is discussed.

The age of criminal responsibility

In recent times there have been claims that the sentencing of serious juvenile offenders does not reflect community sentiment and legal policies are based on outdated ideas about adolescent development. The findings of this thesis call into question the suggestions that the law's assumptions about the development of competence is out of step with community attitudes and developmental research. The professional portfolio examines several hypotheses that have been generated to explain why disabled individuals engage in sexually inappropriate behaviour. It also highlights the importance of exploring the aetiology of this behaviour. Four case reports are presented.

Violent offending, masculinity and age: exploring the role of developmental processes in adulthood

While the link between violent crime and masculinity is often implicitly assumed, to date, research has not specifically investigated beliefs about violence and masculinity at different stages of the adult life-course. This thesis explored the role of maturational processes in the way beliefs about masculinity and violence may differ in early and middle adulthood. Results of a quantitative study did not uncover statistically significant differences between younger and older adult violent offenders on a measure of criminal thinking. However, results of an interpretative phenomenological analysis indicated that beliefs about masculinity may differentially influence violent crime at different stages of adulthood. The results of these two studies provide a foundation for arguing that beliefs about violence and masculinity change throughout the life-course, and that masculinity in particular may be important treatment target in contemporary rehabilitation programs.

An investigation of the developmental assumptions underlying age-based legal criteria in the Children’s Court.

This thesis investigated developmental trends in the psychological abilities presumed to underpin the doli incapax presumption in Victoria, Australia. Findings from this study questioned the utility of the doli incapax presumption as it currently stands, and highlighted the need for a purpose-built interview protocol when assessing young people's culpability.

The effect of victim age on police authorisation of charges in cases of child sexual abuse

In the study, a cohort of 440 child sexual abuse cases were used to model the effect of victim age on police authorisation of charges. Linear and quadratic effects of age were modelled in a logistic regression that controlled for case characteristics and evidence. The quadratic effect of victim age was strengthened when control variables were included in the model and the linear effect of age was not significant in the final model. The results indicated that cases involving victims in middle childhood had a higher proportion of suspects charged than cases involving victims in early childhood and adolescence. Possible mediators of the relationship between victim age and charges were explored and it was found that cases with older victims had a higher prevalence of extra-familial abuse and suspect confessions, and these factors had a positive effect on the proportion of suspects charged. Possible explanations for the quadratic effect of victim age and mediation are discussed.

The effect of complainant age on outcomes in the criminal justice system: case tracking from report to conviction

 The thesis explored child sexual abuse in the criminal justice system and how victim age predicted case outcomes, including disclosures, charges and convictions. The findings highlighted that adolescent victims may experience unique challenges. Further, the relationships between victim age, case characteristics and evidence are crucial to explaining case outcomes.

A child-centered scale of informal social control for Latino parents of preschool-age children: development and validation

Perceived neighborhood informal social control may determine whether parents allow their young children to be physically active in the neighborhood. We developed and validated a scale of neighborhood child-centered informal social control appropriate for Latino parents of preschool-age children. The scale was administered to 240 Latino parents, mainly mothers, recruited from neighborhoods cross-stratified by objectively measured crime and traffic safety. Participants completed measures of community cohesion, perceived signs of physical and social disorder, traffic safety and hazards, and perceived stranger danger. A subsample was reassessed 1 week later to determine test-retest reliability. Confirmatory factor analyses (CFAs) were conducted to examine the fit of the data to a priori measurement models. Construct validity was assessed by estimating the associations of the scale with the other measures. The scale showed good test-retest reliability, and factorial and construct validity. The scale needs to be cross-validated on other samples and Latino fathers.
