Movement Control Strategies in a Dynamic Balance Task in Children With and Without Developmental Coordination Disorder

Abstract

Our study aimed to analyze movement control strategies using predefined criteria for amplitude and differences in these strategies between children with and without DCD. Children with (n?=?28) and without DCD (n?=?15) were included. A video-observation-tool was used to score the moving body parts during a Wii Fit slalom task over multiple time points. Two-step cluster analysis was used to extract distinct movement strategies. Two different movement strategies were identified that were independently validated by a measure of task performance and a subjective mark of quality of the movement. Initial differences between groups and changes over time toward the more successful strategy were found in both groups, albeit in a different percentage. This study shows that the more efficient movement strategy is seen in the majority of the TD children and only in a small number of children with DCD, even after practice.     

Video game preferences and their relation to career interests

The current study used an mTURK sample to determine if there is a relation between video game preferences and career interests. Previous research has found that individual (e.g., personality) differences influence gaming preferences (Zammitto, 2001) and we sought to extend these findings to the domain of career interests. In addition, we examined the potential moderating role of gender. Since researchers have found that gender disparities in spatial attention can be reduced by playing certain types of video games (Feng, Spence, & Pratt, 2007), and it has been demonstrated that spatial ability is an important predictor of success in careers where women are typically underrepresented (Blickenstaff, 2005), we predicted that women with a preference for these types of games (versus a general preference) may have more interest in these careers. We found that gaming motivations were differentially associated with career interests. In addition, gender was found to significantly moderate a number of these relations, such that the association between gaming tendencies and career interests was stronger for women than for men. Findings from the current study should help guide future research that aims to increase the representation of women in STEM careers.
