How planful is routine behavior? A selective-attention model of performance in the Tower of Hanoi. (English)
J. Exp. Psychol.: Gen. 139, No. 1, 95-116 (2010).
Summary: Routine human behavior has often been attributed to plans ‒ mental representations of sequences goals and actions ‒ but can also be attributed to more opportunistic interactions of mind and a structured environment. This study asks whether performance on a task traditionally analyzed in terms of plans can be better understood from a “situated” (or “embodied”) perspective. A saccade-contingent display-updating paradigm is used to change the environment by adding, deleting, and moving task-relevant objects without participants\rq direct awareness. Response latencies, action patterns, and eye movements all indicate that performance is guided not by plans stored in memory but by a control routine bound to objects as needed by perception and selective attention. The results have implications for interpreting everyday task performance and particular neuropsychological deficits.
