The science of reflection

Built on decades of
journaling research

Researchers have studied writing about thoughts and feelings for nearly forty years. Here is what they have found — and how those ideas shape the way MindDrop reflects with you.

What the research suggests

Naming feelings can calm them

Brain-imaging research found that putting feelings into words reduced activity in the brain's alarm centre when people viewed upsetting images.

Writing links to wellbeing

Across well over a hundred randomized studies, writing about thoughts and feelings has been linked to small but real improvements in emotional and physical health.

Clearer thinking

Students who wrote about their stresses showed bigger gains in working memory and fewer intrusive thoughts than those who wrote about trivial topics.

Body awareness matters

Research on interoception — noticing signals from inside the body — connects mindful body awareness with healthier ways of handling emotion.

How MindDrop puts it into practice

  • Mood check-ins help you name what you feel before you write — the same idea studied as affect labelling.
  • Free writing or speaking follows the expressive writing approach: honest, unedited, and private.
  • Somatically aware reflections gently invite you to notice where a feeling lives in your body.
  • Cumulative reflections and Mind History encourage the cause-and-insight thinking linked with clearer processing.

    Putting feelings into words: Affect labeling disrupts amygdala activity

    Lieberman, M. D., et al.

    An fMRI study showing that labelling emotions reduced the amygdala's response to negative images and increased activity in a prefrontal region linked to emotional regulation.

    Expressive writing can increase working memory capacity

    Klein, K., & Boals, A.

    In two semester-long experiments, students who wrote about their thoughts and feelings showed larger working-memory gains and fewer intrusive thoughts. More use of cause and insight words predicted bigger gains.

    Online positive affect journaling in the improvement of mental distress and well-being

    Smyth, J. M., et al.

    A randomized trial of 70 adults with elevated anxiety. Twelve weeks of 15-minute online journaling sessions was associated with less distress and greater wellbeing, with lower anxiety and depressive symptoms after one month versus usual care.
