Day-to-day fluctuations in cognitive precision predict the domain-general intention-behavior gap

Area of Science:

• Cognitive psychology
• Behavioral science
• Psychological measurement

Background:

• Cognitive functioning is theorized to bridge goals and behavior.
• Previous research found weak links between cognitive task performance and real-world outcomes.
• A paradox exists between the expected and observed associations of cognitive abilities and goal-relevant behaviors.

Purpose of the Study:

• To resolve the paradox of weak trait-level associations between cognition and behavior.
• To investigate the predictive power of within-person fluctuations in cognitive function on goal pursuit.
• To explore the dynamic interplay between daily cognitive precision, goal setting, and goal achievement.

Main Methods:

• An intensive longitudinal study over 12 weeks with university students (N=184).
• A microtask design to measure daily fluctuations in cognitive function, goal setting, goal progress, mood, sleep, and motivation.
• Intraindividual (within-person) analysis of state-level data (9248 time points).

Main Results:

• Within-person increases in cognitive processing precision predict same-day goal setting and achievement.
• Cognitive precision predicted goal outcomes across academic and nonacademic domains, controlling for other factors.
• The predictive effect of cognitive precision was comparable to or stronger than fluctuations in mood or motivation and was not moderated by trait self-control or conscientiousness.

Conclusions:

• Shifting from trait-level to state-level analysis resolves the paradox of weak cognitive-behavior associations.
• Daily fluctuations in cognitive precision are crucial, dynamic predictors of goal pursuit.
• Intraindividual analysis reveals significant relationships missed by traditional cross-sectional approaches, advancing our understanding of goal-directed behavior.
