Auditory sensory gating and performance on the Delis–Kaplan Executive Function System

Sensory gating is a neurological mechanism that inhibits redundant sensory information. Impaired sensory gating is not uncommon in otherwise healthy individuals, but its relationship with higher level cognitive function is poorly understood. It is plausible that cognitive fragmentation associated with poor sensory gating may affect an individual's higher level executive functioning. Fifty-one participants (Mean age = 22.02; 24 males) were administered an electroencephalogram with a paired-tone paradigm to measure sensory gating as well as a comprehensive executive functioning battery—the Delis-Kaplan Executive Function System. Overall, better performance on the D-KEFS was related to more effective sensory gating. Also, tasks that measured cognitive flexibility predicted P50 latency as well as P200 amplitude and sensory gating. Understanding the relationship between sensory gating and cognitive processing has implications for healthy individuals and clinical groups alike.
