The Detection Response Task (DRT) is an applied measure of the attentive effects of cognitive load and is evaluated in terms of sensitivity, reliability, and validity. Three DRT variants (head-mounted, remote and tactile) are tested. Performance Operating Characteristics and power analysis are performed. Electroencephalogram is used to validate the DRT as a measure of the brain state of being cognitively loaded. The DRT resulted as sensitive to variations in cognitive task load. Validity of the measure is discussed.
