Investigating the influence of expressive writing exercises on the working memory of middle adolescents and young adults in South Africa

This study investigated the influence of expressive writing on the working memory capacity of middle adolescents (learners 15–17 years old) and young adults (students 18–24 years old) in the South African context. The assumption underlying the research was that expressive writing about a stressful event would reduce unwanted thoughts and the resultant demand on cognitive resources, thereby increasing working memory capacity. Two experiments were conducted involving a sample of 28 school learners and a sample of 38 university students. In each experiment, the participants were assigned to three writing conditions: a factual event for the control group and either just a stressful event, or a solution to a stressful event, for the two experimental groups. It was postulated that the solution-focused group would gain the most from the expressive writing tasks. Working memory capacity assessments were conducted before and after the expressive writing intervention and again about 14 weeks later to test for a long-term effect on working memory capacity. A positive effect was found regarding the working memory capacity of the students, but there was no statistically significant improvement in the working memory capacity of the learners. Furthermore, although the results of the student groups did indicate that an expressive writing intervention may enhance working memory capacity, this effect was not mostly restricted to the solution-focused experimental groups as was hypothesised. Instead, the results suggested that expressive writing exercises may have had a positive effect on the memory performance of all three groups.

Giving words to emotions: the use of linguistic analysis to explore the role of alexithymia in an expressive writing intervention

Expressive writing techniques are methods focusing on written emotional expression that require people to write about traumatic or difficult experiences, with the objective of promoting an elaboration of these events. The general aim of the study is to investigate the influence of alexithymia, a deficit in emotional regulation processes, on the effects of an expressive writing intervention, analyzing the writing protocols through the use of the Linguistic Inquiry and Word Count (LIWIC) and Referential Process (RP) linguistic measures via IDAAP software. Thirty-five women undergoing an assisted reproductive treatment participated in the study and filled out a sociodemographic questionnaire, the 20-item Toronto Alexithymia Scale. They also underwent three session of writing, following a request that they write about their emotions regarding their current situation. The women enrolled were divided into two groups: low alexithymia and high alexithymia, comprising individuals with a TAS-20 total score lower or higher than the mean, respectively. Analyses within the groups during the three writing sessions revealed that the women with low alexithymia reported a greater number of words expressing affectivity, sadness and future perspective, whereas no significances in the high alexithymia group emerged. Moreover, when analysing differences between the groups, high-alexithymia women reported lower scores in RP indexes and fewer words expressing sadness, future perspectives and we verbal. In conclusion, these preliminary findings may confirm the hypothesis that alexithymia affects the effectiveness of expressive writing through a difficulty in becoming involved in the writing process and a lack of symbolizing processes.
