title: Error-related negativity in a visual go/no-go task: children vs. adults.
abstract: Thirteen young adults (ages 21-25) and nine children (ages 7-11) were tested on a visual go/no-go task comparing response times (RTs), error rates, and amplitude and latency changes of error-related negativity (ERN). All experimental conditions were identical for both age groups. Results are consistent with the previous flanker task research showing an increase in ERN amplitude as children age. However, the present results indicate that the peak amplitude of ERN for 9-11 year old children is larger than that of 7-8 year old children, with no difference overall between young adults and children. ERN responses elicited by the flanker task continue to develop until late adolescence. Comparative results suggest that the visual go/no-go task may be more sensitive cognitive measure than the flanker task of mistakes made by children. Differences in time pressure to respond, complexity of the task, and feedback are discussed as possible explanations of differences in the two paradigms.
