The development of involuntary and voluntary attention from childhood to adulthood: A combined behavioral and event-related potential study
Abstract Objective This study investigated auditory involuntary and voluntary attention in children aged 6–8, 10–12 and young adults. The strength of distracting stimuli (20% and 5% pitch changes) and the amount of allocation of attention were varied. Methods In an auditory distraction paradigm event-related potentials (ERPs) and behavioral data were measured from subjects either performing a sound duration discrimination task or watching a silent video. Results Pitch changed sounds caused prolonged reaction times and decreased hit rates in all age groups. Larger distractors (20%) caused stronger distraction in children, but not in adults. The amplitudes of mismatch negativity (MMN), P3a, a…
Distraction and reorientation in children: A behavioral and ERP study
In the context of distraction, involuntary orienting to task-irrelevant deviations and the following reorienting to task-relevant stimulus information were studied in children aged 5-6 years. In an auditory distraction paradigm, reaction times were prolonged by 51 ms in trials including a task-irrelevant stimulus deviancy. Event-related potentials (ERPs) revealed a mismatch response (MMR) at 252 ms and a reorienting negativity (RON) 476 ms post-stimulus in response to deviating sounds. These behavioral and ERP effects resemble those reported for adults. We conclude that kindergarten children are prone to distraction, although they can quite effectively but not fully shield working memory op…
