Setting specific goals improves cognitive effort, self-efficacy, and sustained attention.

Investigating the efficacy of goal-setting strategies is critical in understanding how individuals regulate their behavior, particularly within cognitive tasks. The present study examines the impact of self-set versus experimenter-set goals and point incentives on performance across three experiments using two sustained attention tasks. In Experiment 1, we compared self-set and experimenter-set goals in the psychomotor vigilance task, hypothesizing that self-set goals would lead to better performance due to increased agency. No significant differences emerged in task performance between the two conditions. Participants who self-set their goals also set increasingly easier goal standards over time. Experiment 2 introduced a novel task paradigm "Green Means Go," modeled after the psychomotor vigilance task, and revealed faster reaction times in goal-setting conditions compared to a no-goal condition. Having a specific goal, either self-set or experimenter-set, was better for performance than having no goals. Experiment 3 allowed all participants to set their own goals and explored the influence of a points-based incentivization system on goal-setting tendencies. Those who received points set more difficult goals. Findings suggest that goal-setting mechanisms can enhance task performance and help reduce vigilance decrements, with potential implications for using goal-setting to elevate cognitive performance.
