Specific language impairment, theory of mind, and visual perspective taking: evidence for simulation theory and the developmental role of language

Recent research has found that the acquisition of theory of mind (ToM) is delayed in children with specific language impairment (SLI). The present study used a battery of ToM and visual perspective taking (VPT) tasks to investigate whether the delayed acquisition of ToM in children with SLI is associated with delayed VPT development. Harris' (1992, 1996) simulation theory predicts that the development of VPT will be delayed. Participants were 20 children with SLI (M=62.9 months) and 20 typically developing children (M=61.2 months) who were matched for nonverbal ability, gender, and age. The results supported Harris' theory and a role for language in ToM and VPT development.     

Effects of resistance training performed to repetition failure or non-failure on muscular strength and hypertrophy: A systematic review and meta-analysis

Purpose:We aimed to perform a systematic review and meta-analysis of the effects of training to muscle failure or non-failure on muscular strength and hypertrophy.Methods:Meta-analyses of effect sizes(ESs)explored the effects of training to failure vs.non-failure on strength and hypertrophy.Subgroup meta-analyses explored potential moderating effects of variables such as training status(trained vs.untrained),training volume(volume equated vs.volume non-equated),body region(upper vs.lower),exercise selection(multi-vs.single-joint exercises(only for strength)),and study design(independent vs.dependent groups).Results:Fifteen studies were included in the review.All studies included young adults as participants.Meta-analysis indicated no significant difference between the training conditions for muscular strength(ES=-0.09,95%confidence interval(95%CI):-0.22 to 0.05)and for hypertrophy(ES=0.22,95%CI:-0.11 to 0.55).Subgroup analyses that stratified the studies according to body region,exercise selection,or study design showed no significant differences between training conditions.In studies that did not equate training volume between the groups,the analysis showed significant favoring of non-failure training on strength gains(ES=-0.32,95%CI:-0.57 to-0.07).In the subgroup analysis for resistance-trained individuals,the analysis showed a significant effect of training to failure for muscle hypertrophy(ES=0.15,95%CI:0.03-0.26).Conclusion:Training to muscle failure does not seem to be required for gains in strength and muscle size.However,training in this manner does not seem to have detrimental effects on these adaptations,either.More studies should be conducted among older adults and highly trained individuals to improve the generalizability of these findings.     

Organisational readiness and capacity building strategies of sporting organisations to promote health

This paper explored the readiness of Victorian State Sporting Organisations (SSOs) in Australia to implement health promotion (HP) programs and sought to understand how they implemented capacity building strategies to promote health. Ten SSOs that received funding to develop and implement HP were recruited for the study. Interviews were conducted with key staff from SSOs and focus groups were undertaken with their Boards of Management. Factors analysed were SSO organisational readiness and capacity building strategies to implement change in organisational processes, organisation and resources, and systems and controls. SSOs made a concerted effort to create and support sport and recreation contexts that promote healthy behaviours. A number of SSOs achieved changes in their culture and systems by implementing formalised and systematic programs such as the club development program. The club development program supported the implementation and sustainability of HP throughout the organisational system of the SSO. These changes, however, were dependent upon organisational readiness; particularly climate and capacity, whereby financially “well off” SSOs had the capacity to engage in HP in a significant way. This paper highlights opportunities and challenges for policy makers to fund HP within sporting organisations; especially when the delivery of sport is a more immediate responsibility than HP.     

The effects of school board consolidation and financing on student performance

Over the last 20 years, states and provinces have become increasingly involved in the financing and administration of elementary and secondary education. Local school boards, however, still retain control over key aspects of the provision of education. Historically, these boards were organized at the community level so as to meet the wants of the local community. Today, states and provinces have become more interested in consolidating school boards and moving to a more centralized funding scheme. Do these changes result in improved student achievement? This paper attempts to answer these questions by examining the school board consolidation and funding changes instituted by the province of Ontario. We differentiate the effects of the policy changes based on observed differences in the school boards prior to consolidation. We show that students in previously high wealth school boards perform worse after the policy change compared to students in previously low wealth school boards.

Validation of the Stanford-Binet Intelligence Scale: Fourth edition with exceptional black male students

Standard Age Scores on the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) and WISC-R IQs of 51 urban black males receiving special education services were compared. Correlations between the SBIV Composite scores and WISC-R Verbal, Performance, and Full Scale IQs were 0.803, 0.826, and 0.87 respectively. Correlations between all combinations of scales ranged from 0.612 to 0.888, median r=.723. SBIV Composite mean scores did not differ significantly from the mean WISC-R Full Scale, Verbal, and Performance IQs. Regression analysis of the three subgroups (BD. LD, and EMR) indicated that the SBIV possesses differential validity for each group. Tabular comparison of precision of classification between the SBIV and the WISC-R yielded a 78% agreement. These data suggest that the SBIV possesses utility for assessing the intelligence of black students classified as BD and EMR. However, the use of the scale with LD students is unsupported.
