Concurrent validity of the wide range assessment of visual motor abilities in typically developing children ages 4 to 11 years

Pediatric clinicians working with school-age children use the Wide Range Assessment of Visual Motor Abilities (WRAVMA) as a method for evaluating visual perception and motor skills in children despite limited information on concurrent validity. Whether it may be substituted for the Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI) and has suitable estimates of concurrent validity were examined with a convenience sample of 91 typically developing children ages 4 to 11 years. No systematic concurrent validity between the WRAVMA and the VMI emerged. Only two subtests of the WRAVMA (Matching with Visual Perception, and Pegboard with Motor Coordination) gave scores statistically significantly correlated with those on the VMI, and these correlations were weak, accounting for very small amounts of the shared variance. As such, they have low clinical relevance. These findings do not provide evidence of concurrent validity to support the use of WRAVMA as an alternative method for the VMI for assessing children's visual perception and motor skills.     

The involvement of epigenetic defects in mental retardation

Mental retardation is a group of cognitive disorders with a significant worldwide prevalence rate. This high rate, together with the considerable familial and societal burden resulting from these disorders, makes it an important focus for prevention and intervention. While the diseases associated with mental retardation are diverse, a significant number are linked with disruptions in epigenetic mechanisms, mainly due to loss-of-function mutations in genes that are key components of the epigenetic machinery. Additionally, several disorders classed as imprinting syndromes are associated with mental retardation. This review will discuss the epigenetic abnormalities associated with mental retardation, and will highlight their importance for diagnosis, treatment, and prevention of these disorders.     

Effects of concurrent monitoring on cognitive load and performance as a function of task complexity

For self‐regulated learning to be effective, students or trainees need to be able to accurately monitor their performance while they are working on a task, use the outcomes as input for self‐assessment of that performance after completing the task and select an appropriate new learning task in response to that assessment. From a cognitive load perspective, monitoring can be seen as a secondary task that may become hard to maintain and hamper performance on the primary task under high load conditions. The experiment presented here investigated the effects of concurrent performance monitoring on cognitive load and performance as a function of task complexity. Results showed that monitoring significantly decreased performance and increased cognitive load on complex, but not on simple tasks. The findings are discussed in terms of theoretical consequences and instructional design for self‐regulated learning. Copyright © 2010 John Wiley & Sons, Ltd.     

Early educational foundations for the development of civic responsibility: an African experience

An innovative curriculum designed to foster the development of social responsibility among pre-adolescent children was introduced at a rural Zambian primary school. The curriculum invoked Child-to-Child principles focusing on health education, advancing a synthesis of Western psychological theories and African cultural traditions. The teacher sought to democratize the educational process through cooperative learning in mixed-gender, mixed-social-class, and mixed-ability study groups. Learners engaged in community service activities and contributed to the nurturant care of younger children. Young adults interviewed seventeen years after completing the program recalled their experience and reflected on how it had promoted their personal agency, cooperative disposition, and civic responsibility in early adulthood.     

Measuring motor speed through typing: a surrogate for the finger tapping test

Motor speed is an important indicator and predictor of both cognitive and physical function. One common assessment of motor speed is the finger-tapping test (FTT), which is typically administered as part of a neurological or neuropsychological assessment. However, the FTT suffers from several limitations, including infrequent in-person administration, the need for a trained assessor and dedicated equipment, and potential short-term sensory–motor fatigue. In this article, we propose an alternative method of measuring motor speed, with face validity to the FTT, that addresses these limitations by measuring the interkeystroke intervals (IKI) of familiar and repeated login data collected in the home during a subject’s regular computer use. We show significant correlations between the mean tapping speeds from the FTT and the median IKIs of the nondominant (r = .77) and dominant (r = .70) hands, respectively, in an elderly cohort of subjects living independently. Finally, we discuss how the proposed method for measuring motor speed fits well into the framework of unobtrusive and continuous in-home assessment.     

Bidirectional influences in mother–toddler dyads: an examination of the relative influence of mothers' and children's behaviours

This study examined bidirectional relationship between mothers' lax and overreactive discipline and children's misbehaviour and negative effect. We examined the moment‐to‐moment stability of mothers' and children's behaviours (actor effects) and mothers' and children's influence on their partners' subsequent behaviours (partner effects). Participants were 71 mothers and their 24‐ to 48‐month‐old children observed during a 30‐min interaction. Both children and mothers exhibited stability in their own behaviours and influenced the subsequent behaviours of their partners. Additionally, a comparison of partner effects indicated that overreactive discipline more strongly predicted child's negative effect than child's negative effect predicted overreactive discipline. In contrast, although a child's negative effect predicted lax discipline, lax discipline did not predict subsequent child's negative effect. Copyright © 2010 John Wiley & Sons, Ltd.     

The Effect of a Computerized Decision Aid on the Development of Knowledge

This study provides evidence on how the use of a computerized decision aid affects knowledge acquisition. While the intent of such computer-based decision aids is to improve and support unaided human judgments, it is unclear whether the use of the aids actually facilitate knowledge transfer. Seventy-six subjects completed a hypothetical decision task where one of two types of decision aids was used: an expert system or traditional textual materials. Results suggest that those using a computer-based decision aid acquired and encoded in memory less declarative knowledge than those using textual reference materials. Implications of the findings are discussed.     

Self-Efficacy as a Mediator of the Relationship Between Causal Attributions and Exercise Behavior

The primary purposes of this study were to examine whether the attribution–intention link was mediated by self-efficacy and whether the attribution–behavior link was mediated by self-efficacy. As a secondary purpose, we examined whether the attribution–behavior link was mediated by exercise intentions. These relationships were tested prospectively at multiple time points. Participants were 260 adult exercisers ( M age=32 years) enrolled in 12 weeks of structured exercise classes. Social cognitive measures were assessed at early and midprogram; attendance was tracked for the first and second half of the program. Hierarchical multiple regression procedures indicated support for self-efficacy as a mediator of the relationship between attributions and behavior. Secondary analyses revealed support for intention as a mediator of the attribution–behavior relationship. Finally, additive relationships in support of social cognitive theory also were detected. The attribution/self-efficacy/behavior link is important for adherence interventions and should be investigated further in both asymptomatic and symptomatic populations.     

Effects of modeling rote versus varied responses on response variability and skill acquisition during discrete‐trial instruction

Despite its advantages, discrete‐trial instruction (DTI) has been criticized for producing rote responding. Although there is little research supporting this claim, if true, this may be problematic given the propensity of children with autism to engage in restricted and repetitive behavior. One feature that is common in DTI that may contribute to rote responding is the prompting and reinforcement of one correct response per discriminative stimulus. To evaluate the potential negative effects of rote prompts on varied responding, we compared the effects of modeling rote versus varied target responses during the teaching of intraverbal categorization. We also evaluated the effects of these procedures on the efficiency of acquisition of any one correct response. For all four children, any increase in varied responding was fleeting, and for two participants, acquisition was slower in the variable‐modeling condition.
