Abstract | Working memory is a vital executive function that predicts a wide range of life
outcomes. Over the years, researchers have been identifying ways to improve working
memory capacity. With the rising popularity of mindfulness apps, empirical studies began in
the area to examine their efficacies on both psychological and cognitive outcomes. The
current study examined whether a 10-day smartphone-based mindfulness intervention
provided by Headspace effectively improves working memory capacity in a randomized
controlled trial. The result was compared against a 10-day relaxation music program. The
current study also explored the mediation role of rumination as the underlying mechanism.
The final sample consists of 51 participants, 28 in the experimental (Headspace) group and
23 in the active control (relaxation music) group. Results suggest that the working memory
capacity in the Headspace group was marginally significantly improved upon completion of
the intervention. However, the increase was not significantly higher than that of the
relaxation music group. Mediation analysis revealed that the indirect effect of decreased
rumination was not significant. Implications and limitations of the study were discussed.
