The influence of mood on working memory capacity has been investigated in adults,
albeit with conflicting results, but remains relatively unexplored in children.
The present study examined the effect of a mood induction procedure on
phonological working memory capacity in fourth and fifth graders. An initial
working memory span test was followed first by a collective mood induction
procedure, then by a second working memory span test. Results showed an effect
of mood induction procedure on phonological working memory performances, with
decreasing scores in the case of negative mood. These results suggest that, in
certain contexts and situations, negative emotion has an impact on children’s
cognitive abilities.
