Goal neglect and working memory capacity in 4- to 6-year-old children.

Goal neglect is the phenomenon of failing to execute the momentary demands of a task despite understanding and being able to recall the task instructions. Successful goal maintenance is more likely to occur in adults with high working memory capacity (WMC) who can keep rules mentally accessible while performing the task. The current study predicted that goal neglect would also be related to WMC in children. It assessed thirty-seven 4-year-old and twenty-eight 6-year-old children on the goal neglect version of the Dimensional Change Card Sort, and 3 tasks that measure WMC. As predicted, children with higher WMC scores were more likely to maintain goals adequately for task performance. The findings are consistent with a 2-factor model of working memory and its development.
