Distractibility of Noise during Post Concussion Visual Search
Christopher Koch
Abstract. Noise can differentially influence cognitive performance among concussed individuals. Eight concussed subjects were compared to seven matched controls. Subjects completed a search task while listening to a recording. Subjects had faster response times for feature searches and for target present searches. No differences were found between groups. Concussed individuals recalled more information about the lecture. These findings suggest that visual search may not be cognitively demanding enough to produce decrements in performance in the presence of noise.
