The ability to appropriately select, initiate, or withhold appropriate behaviors in a complex environment is a taxing ability that is impaired in individuals with MCI.In order to further explore the conceptual processing involved in response inhibition, individuals both with MCI and without completed a go/no-go task while event-related potentials were recorded. The findings suggested that as the conceptual demand of the task increased, the worse the individuals with MCI performed compared to the controls. This suggests that in complex real-life situations, inhibitory processing is impacted by conceptual demand in individuals with MCI more than in the normal aging population.
