To identify conditions that foster dual-task integrality by evaluating the roles of display proximity, single-object integration, intertask redundancy, and cognitive resource allocation.
Laboratory study of twelve subjects evaluated across three experimental sessions performing single- and dual-task paradigms.
Subjects completed a primary pursuit step tracking task combined with secondary stimulus intensity or spatial position discrimination tasks.
Cognitive resource allocation was tracked by measuring P300 amplitude changes in event-related brain potentials.
Task pairings requiring the processing of different features of the same object yielded superior dual-task performance compared to processing distinct objects.
Same-object task pairs demonstrated a positive relationship between primary task difficulty and the cognitive resources allocated to secondary task stimuli.
Physical display proximity and intertask redundancy produced similar facilitative effects, but with smaller overall magnitudes.

Implication

Experimental study reveals enhanced performance during dual tasks sharing single-object properties in healthy adults, indicating that perceptual integration optimizes cognitive resource allocation.
