Overview

The ability to select, initiate or withhold appropriate behaviors in a complex environment can be taxing, especially for individuals with mild cognitive impairement (MCI).In order to further explore the conceptual processing involved in response inhibition, two groups (individuals with MCI and a control group of individuals without MCI) completed a go/no-go task while event-related potentials were recorded. Findings suggest that as the conceptual demand of a task increases, the performance of individuals with MCI deteriorates in comparison to the control group, suggesting complex, real-life situations can impact inhibitory processing by conceptual demand in individuals with MCI more so than in the general population.
