Recent research published in the Quarterly Journal of Experimental Psychology suggests that even brief periods of mindfulness meditation (Buddhist sati) can have a profound impact on our ability to learn and make decisions.

Participants who practiced mindfulness meditation not only enhanced their ability to learn from unexpectedly positive outcomes but also demonstrated increased openness to new experiences, favoring exploration of novel options over reliance on familiar choices.

A growing body of evidence suggesting that mindfulness meditation, a practice rooted in ancient spiritual traditions in Buddhism and now integral to various contemporary psychological therapies, could have far-reaching effects on cognitive flexibility, emotional regulation, and stress reduction.

Beyond these recognized benefits, the researchers behind the new study sought to understand if and how a brief mindfulness intervention could directly influence the way individuals learn from feedback in decision-making scenarios, where outcomes are not guaranteed.

“Our interest in this topic was driven by the recognition of mindfulness meditation’s remarkably potent influence on human cognition and its capacity to modify deeply rooted social biases,” explained study author Marius Golubickis, a lecturer at the University of Aberdeen and head of the Aberdeen Computational Social Cognition Lab.

“The revelation that even brief, 5-minute meditation sessions can exert substantial impacts highlights the practicality and accessibility of these practices for people leading busy lives. This exploration into the simplicity and efficiency of mindfulness meditation opens fascinating avenues for enhancing learning and personal development, highlighting its vital role in our cognitive toolkit.”

The researchers recruited a sample of 60 participants with minimal to no prior experience in meditation. Participants’ backgrounds were diverse in terms of educational attainment, ranging from high school education to Ph.D. degrees.

These participants were randomly assigned to one of two groups, a mindfulness meditation group or a control group.

For those in the mindfulness group, the intervention consisted of a 5-minute guided meditation focused on mindful breathing. This exercise aimed to cultivate attention on the present moment in a non-judgmental manner, guiding participants to observe their breath and gently redirect their focus whenever distractions arose.

On the other hand, the control group engaged in a 5-minute task involving Chinese puzzles (Tangram), selected as a neutral activity unlikely to influence cognitive or emotional states in the same manner as mindfulness meditation.

Following these activities, all participants embarked on the primary experimental task: a Probabilistic Selection Task.

This task was designed to simulate decision-making under uncertainty, requiring participants to choose between pairs of symbols based on probabilistic feedback about their correctness.

The symbols, derived from Japanese Hiragana characters, were presented in pairs (AB, CD, EF), with each pair having a defined probability that choosing one symbol would result in positive feedback.

For example, choosing symbol A over B would yield a correct response 80% of the time.

This structure allowed the researchers to create a learning environment where participants had to discern and adapt to these probabilities over time, mirroring real-life decisions where outcomes are often uncertain.

To analyze the data, the researchers employed advanced computational modeling techniques, specifically the Reinforcement Learning Drift Diffusion Model (RL-DDM).

This model integrates reinforcement learning theories, which explain how behavior is shaped by feedback, with decision-making processes, capturing both the choice probabilities and the response times.

Golubickis and his colleagues found that participants who engaged in the mindfulness meditation session showed an enhanced ability to learn from positive feedback in uncertain decision-making scenarios compared to those in the control group.

This enhanced learning rate following positive feedback suggests that mindfulness meditation helps individuals to more effectively process and utilize information that exceeds their expectations, thereby optimizing their decision-making process in situations characterized by uncertainty.

The computational modeling analysis provided insights into the cognitive mechanisms underpinning these effects.

Mindfulness meditation appeared to influence several key cognitive processes involved in learning and decision-making.

Specifically, the meditation group exhibited faster learning rates from positive prediction errors, meaning they were quicker to adjust their expectations and behavior based on unexpectedly positive outcomes.

“Perhaps the most remarkable finding was the significant impact of brief mindfulness on the learning process, particularly its ability to heighten sensitivity to positive surprises,” Golubickis told PsyPost.

“This nuanced alteration suggests that even short periods of mindfulness meditation can profoundly influence our cognitive responses to unexpected positive outcomes, underscoring the potential for mindfulness to enhance how we perceive and learn from our experiences.”

The mindfulness group also displayed increased response caution, as evidenced by a higher decision threshold in the RL-DDM analysis.

This finding implies that mindfulness meditation leads individuals to require more evidence before making a decision, reflecting a more deliberate and less impulsive approach to choosing among uncertain options.

Additionally, the researchers found that mindfulness meditation influenced the tendency to explore rather than exploit, as indicated by changes in drift rate scaling — a measure of how strongly participants favored options with the highest expected value.

This shift towards exploration suggests that mindfulness encourages a more balanced approach to decision-making, where the value of gathering new information and experiencing novel outcomes is appreciated alongside the safety of sticking with known, rewarding options.

“Anchored in the fundamental premise that learning primarily occurs through making a mistake and receiving feedback, our study illuminates how a brief mindfulness intervention can refine this learning mechanism,” Golubickis explained.

“Specifically, it enhances how we process and benefit from feedback that surpasses expectations.”

“Consider a situation where someone anticipates a modest improvement in their skill after practice but experiences a significant leap instead.

Mindfulness also cultivates a disposition towards open-minded exploration, encouraging individuals to venture beyond known territories, show a willingness to consider competing viewpoints, and embrace new possibilities and alternative viewpoints.”

The findings reinforce the cognitive benefits of mindfulness meditation. But the research has some caveats, including the exclusive focus on one form of mindfulness practice and its immediate effects.

The longevity of these cognitive enhancements and their evolution with sustained mindfulness practice remain areas ripe for further exploration.

“A significant limitation of our study is the uncertainty regarding the duration of mindfulness effects on learning,” Golubickis said.

“These effects could last for 15 minutes or extend for several hours; the exact timeframe remains unclear.

Additionally, it’s unknown how these effects might evolve with long-term mindfulness practice, raising questions about the sustainability and potential growth of benefits over time.”

The researchers express an interest in broadening this inquiry to understand how mindfulness can intersect with various cognitive functions and serve as a tool for mental health interventions.

The potential of leveraging new technologies and computational methods to deepen our understanding of mindfulness and cognition also presents an exciting frontier for future research.

“Moving forward, our research will investigate mindfulness’s impact across cognitive functions, and of course its utility in mental health interventions,” Golubickis told PsyPost.

“A comprehensive approach to psychological well-being aligned with cognitive enhancements would be beneficial.” “I would like to underscore the potential of new techniques and methodologies in this area of research,” he added.

“Along with AI computation and Digital Transformation, these technologies potentially offer invaluable insights, opening up new perspectives and enhancing our understanding in ways that would not be possible through traditional research approaches alone.

It can significantly enrich our analyses, providing a deeper, comprehension of cognition.”
