Abstract
Visual changes constantly occur in the environment (e.g., changes in traffic, people shifting positions). Change detection is the ability to notice changes in the world around us (Rensink, 2002); it can denote proper detection (i.e., reporting the existence of a change), identification (i.e., reporting the nature of the change), and localization (i.e., reporting where the change occurred). When a change to a scene coincides with another event that disrupts the motion signal, which would normally draw attention to a change, observers often fail to detect large changes (Beck, Angelone, & Levin, 2004). The term, change blindness, refers to the difficulty observers have in detecting changes to a visual scene (Simons & Rensink, 2005). The current study examined the role of individual differences in attention (e.g., attention deficit/hyperactivity disorder, boredom proneness, cognitive failures) to predict the ability to detect changes. Undergraduate students were randomly assigned to either the control group (completed only change blindness task) or the experimental group (completed a simultaneous auditory task). Increased workload created by the auditory task significantly decreased change detection performance. The results suggest that although the primary and secondary task utilized different sensory modalities, multitasking negatively impacted performance.
