Differential development of visual attention skills in school-age children.

ABSTRACT: Children aged 7-17 years and adults aged 18-22 years were tested on three aspects of visual attention: the ability to distribute visual attention across the field to search for a target, the time required for attention to recover from being directed towards a target, and the number of objects to which attention can be simultaneously allocated. The data suggested different developmental trajectories for these components of visual attention within the same set of participants. This suggests that, to some extent, spatial, temporal and object-based attentional processes are subserved by different neural resources which develop at different rate. In addition, participants who played action games showed enhanced performance on all aspects of attention tested as compared to non-gamers. These findings reveal a potential facilitation of development of attentional skills in children who are avid players of action video games. As these games are predominantly drawing a male audience, young girls are at risk of under-performing on such tests, calling for a careful control of video game usage when assessing gender differences in attentional tasks.

Project description:OBJECTIVE:Previous research has found that preschoolers with hearing loss have worse visual attention and elevated rates of behavior problems when compared to typically hearing peers (Barker et al., 2009). However, little is known about these deficits in school-age children with cochlear implants (CIs). We evaluated visual selective attention in school-age children with CIs and hearing peers and examined the link between visual attention and behavior problems. METHOD:Data were drawn from the Childhood Development after Cochlear Implantation (CDaCI) study, the largest longitudinal, multi-site study of children with CIs. Visual attention was measured using d prime (d') on a continuous performance test (The Gordon CPT), which requires participants to watch a stream of digits and hit a button after seeing a certain target (a 9 following a 1). The CPT captures the probability of a hit (pressing button for a target) vs a false alarm (pressing the button for a non-target) while accounting for chance responding. In addition, predictors of visual attention, including IQ (using Processing Speed and Perceptional Reasoning on the WISC-IV), age at implantation, gender, and device management were examined. Externalizing problems were assessed using parent-report on the BASC-2. Data were drawn from 60 months post-implantation. RESULTS:Children with CIs (n?=?106) showed significantly worse visual selective attention than hearing peers. The difference in d' was driven by higher rates of false alarms. In the CI group, the Processing Speed Index on the WISC was correlated with total omissions, total commissions and d'. Within the CI group, d' significantly predicted parent-reported externalizing behavior problems. This finding was primarily driven by elevated Hyperactivity in the CI group. CONCLUSION:Children with CIs continue to display deficits in visual attention when compared to their hearing peers. Despite improvements in oral language, these problems have critical implications for academic performance and social competence. Currently, cochlear implant teams do not focus on these other dimensions of development and thus, may not be positioned to address them. Assessment of attention and behavior should be incorporated into routine, annual visits soon after implant surgery, and remediation of these deficits should be included in early intervention programs.

Project description:PurposeThis article reviews research on executive function (EF) skills in children with autism spectrum disorder (ASD) and the relation between EF and language abilities. The current study assessed EF using nonverbal tasks of inhibition, shifting, and updating of working memory (WM) in school-age children with ASD. It also evaluated the association between children's receptive and expressive language abilities and EF performance.MethodIn this study, we sought to address variables that have contributed to inconsistencies in this area of research-including task issues, group comparisons, and participant heterogeneity. EF abilities in children with ASD (n = 48) were compared to typically developing controls (n = 71) matched on age, as well as when statistically controlling for group differences in nonverbal cognition, socioeconomic status, and social communication abilities. Six nonverbal EF tasks were administered-2 each to evaluate inhibition, shifting, and WM. Language abilities were assessed via a standardized language measure. Language-EF associations were examined for the ASD group as a whole and subdivided by language status.ResultsChildren with ASD exhibited significant deficits in all components of EF compared to age-mates and showed particular difficulty with shifting after accounting for group differences in nonverbal cognition. Controlling for social communication-a core deficit in ASD-eliminated group differences in EF performance. A modest association was observed between language (especially comprehension) and EF skills, with some evidence of different patterns between children on the autism spectrum with and without language impairment.ConclusionsThere is a need for future research to examine the direction of influence between EF and language. It would be beneficial for EF interventions with children with ASD to consider language outcomes and, conversely, to examine whether specific language training facilitates aspects of executive control in children on the autism spectrum.Presentation videohttps://doi.org/10.23641/asha.7298144.
