title: Examining the impact of formal planning on performance in older adults using a naturalistic task paradigm.
abstract: Thirty-two younger adults (YAs) and 64 older adults (OAs) completed the Amap Task, a naturalistic measure designed to evaluate the formulation and execution stages of planning. Participants read a map layout of a university apartment and planned an efficient strategy to complete several tasks. To determine whether execution abilities are augmented by formulating a plan, we compared formal (i.e., written strategy) and informal (i.e., initiate task when ready without writing out a strategy) planning conditions. Participants did not have access to their plan during task execution. Amap scores were also compared with informant-report of everyday functioning. For the formal planning condition, OAs were less accurate and less efficient than YAs during the formulation stage, while there were no group differences in total formulation time for the informal planning condition. Across conditions, OAs obtained poorer execution accuracy and efficiency scores, took longer during execution, and omitted more task parts. Formal planning improved execution efficiency but not accuracy, suggesting one's approach to the task (i.e., efficiency, finesse) may improve with preplanning even if overall accuracy does not. Significant relationships between Amap scores and informant-report of everyday functioning highlight the ecological validity of the Amap as a measure sensitive to everyday planning abilities.
