Enhanced declarative memory in long-term mindfulness practitioners.

Area of Science:

• Cognitive Neuroscience
• Psychology

Background:

• Mindfulness meditation (MM) is linked to health benefits, with prior studies suggesting positive effects on memory.
• The impact of long-term MM training on declarative memory remains less understood.

Purpose of the Study:

• To investigate how long-term MM practice influences declarative memory formation across various memory types.
• To explore the relationship between trait mindfulness, memory performance, and anxiety in MM practitioners.

Main Methods:

• Compared memory performance in experienced MM practitioners (n=23) and meditation-naïve controls (n=22).
• Utilized diverse declarative memory tests: item recognition, narrative, autobiographical memory, and future projection.
• Assessed participants using the Five Facet Mindfulness Questionnaire (FFMQ) and State-Trait Anxiety Inventory (STAI).

Main Results:

• Long-term MM practitioners showed superior performance in picture recognition compared to controls.
• MM practitioners reported enhanced vividness in autobiographical memory retrieval and future simulations.
• A significant positive correlation between trait mindfulness and memory performance was observed exclusively in the MM group.

Conclusions:

• Long-term MM training demonstrably benefits declarative memory, extending findings from short-term training studies.
• Trait mindfulness is positively associated with declarative memory performance in the context of MM practice.
• Findings suggest potential roles for self-mode, cognitive diffusion, attention, and emotion in MM-related memory enhancement.
