Abstrakt: Purpose: A meta-analysis investigating attentional shifting in children with developmental language disorder (DLD) was conducted. Task type, participant age, and dependent variable metric were examined as significant moderators.
Method: A systematic literature review identified 20 studies that met the following inclusionary criteria:(a) were published between 1994-2018; (b) included children with DLD aged 3;00 to 17;11 years; and (c) used behavioral performance-based measures of attentional shifting.
Results: Children with DLD performed poorer than age-matched peers with typically developing language (TL) by 0.42 SD across attentional shifting studies. Moderator analyses showed an effect of task type, as children with DLD performed comparatively poorer on set-shifting (g = -.52) but not alternating tasks (g = -.18). Neither age nor dependent variable used to measure attentional shifting were significant moderators.
Discussion: Children with DLD exhibit deficits in attentional shifting relative to same-age peers. Results of moderator analyses reveal that deficits were found on set-shifting but not alternating tasks and that these deficits remained consistent whether researchers measure accuracy or response time switch costs to ascertain attentional shifting ability. In addition, moderator analysis results suggest that attentional shifting deficits are consistent in preschool-age and school-age children with DLD.
