Abstract Synopsis

  • Expressive writing involving emotional disclosure can boost working memory (WM) capacity, as shown in two semester-long studies.
  • Students who wrote about personal experiences or feelings about college or negative events experienced greater increases in WM and fewer intrusive thoughts compared to those who wrote about trivial topics.
  • The improvement in WM is explained by the idea that expressive writing helps reduce distracting, avoidant thoughts, freeing up mental resources for better working memory functioning.]
