Greater mindful eating practice is associated with better reversal learning

Area of Science:

• Behavioral neuroscience
• Clinical psychology
• Cognitive science

Background:

• Mindfulness-based interventions are hypothesized to reduce compulsive behaviors like overeating by enhancing behavioral flexibility.
• Reversal learning serves as a direct measure of behavioral flexibility.

Purpose of the Study:

• To investigate if an 8-week mindful eating intervention improves reversal learning compared to an educational cooking intervention.
• To assess the impact of mindful eating on behavioral flexibility in a non-clinical population.

Main Methods:

• A deterministic reversal learning task was administered at baseline and post-intervention.
• Sixty-five healthy participants with varying BMIs (19-35 kg/m2) were recruited.
• Participants were randomized to either a mindful eating or an educational cooking intervention group.

Main Results:

• No significant group differences in reversal learning were found between the mindful eating and educational cooking groups.
• Increased time invested in mindful eating practice positively correlated with improvements in reversal learning.
• This correlation was independent of outcome valence (reward vs. punishment).

Conclusions:

• Greater engagement in mindfulness practice may enhance behavioral flexibility.
• Mindfulness-induced improvements in behavioral flexibility show potential for addressing compulsive eating behaviors.
• Further research is warranted to explore these effects in clinical populations.
