Motivational and implicit processes contribute to incidental physical activity.

Area of Science:

• Behavioral Science
• Psychology
• Health Promotion

Background:

• Physical activity offers significant health benefits and disease prevention.
• Understanding factors influencing incidental physical activity is crucial for promoting public health.
• Existing research highlights motivation and implicit processes as individual contributors to physical activity.

Purpose of the Study:

• To investigate how motivational properties (autonomous and controlled motivation) interact with implicit processes (attitudes, attentional biases, approach-avoid biases) to influence incidental physical activity.
• To explore the psychological mechanisms underlying incidental physical activity engagement.

Main Methods:

• A correlational study involving 103 participants who recorded 7-day step counts.
• Measurement of implicit attitudes (SC-IAT), attentional biases (dot probe), and approach-avoid biases (manikin tasks).
• Assessment of autonomous and controlled motivation using the Perceived Locus of Causality Questionnaire.

Main Results:

• Implicit attitudes and both autonomous and controlled motivation were independently linked to incidental physical activity.
• Motivation interacted with approach-avoid bias to predict physical activity levels, with motivation positively associated with step count in individuals with high avoid bias.
• No significant interaction was found between motivation and attentional bias.

Conclusions:

• Findings support the integration of self-determination theory and dual process models in understanding incidental physical activity.
• Both autonomous and controlled motivation, in conjunction with specific implicit processes like approach-avoid bias, contribute to incidental physical activity.
• This research provides foundational insights into the psychological drivers of incidental physical activity.
