Inhibition is an important aspect of executive functioning (EF) that refers to a cognitive mechanism that blocks or suppresses irrelevant stimuli, memory, habitual responses, or automatized processes from interrupting the desired response. Researchers have found weak and inconsistent relations between inhibitory abilities and mathematics performance (Bull & Lee, 2014). Given anecdotal evidence of the effects of external distraction or intruding thoughts on the ability to stay on task, it is surprising that inhibitory abilities do not have a more prominent role. In this article, we argue that this lower‐than‐expected association is due to (a) age‐related changes in EF, (b) the sensitivity of inhibitory tasks commonly used in studies, (c) a mismatch in how susceptibility to interference and mathematical performance are measured, and (d) the choice of criterion measures, with some mathematical tasks imposing less inhibitory demands than others.

Many studies have used event-related potential and neural oscillations to probe the underlying neural mechanisms of inhibitory control in adults, but little has been done in typically developing preschoolers. In this study we tested healthy preschool children between the ages of 5 and 6, and observed better response inhibition in 6-year-olds compared to 5-year-olds. Importantly, this age-related difference could not be explained by the N2 component from event-related potential, but was reflected in an increase in right frontal beta power from electroencephalogram. These results suggest that frontal beta power during the preschool period may reflect neural development of inhibitory control. [ABSTRACT FROM AUTHOR]
