For better or for worse: differential effects of the emotional valence of words on children's recall.

Recent research has revealed the widespread effects of emotion on cognitive functions and memory. However, the influence of emotional valence on verbal short-term memory remains largely unexplored, especially in children. This study measured the effect of emotional valence on word immediate serial recall in 4-6-year-old French children (N = 124). Results show a robust effect of emotional valence on recall performances and recall errors. More precisely, we observed a facilitating effect of the positive valence of words: it allows better performance and causes few recall errors. On the contrary, the data indicated a disruptive impact of negative word valence: the latter causes very low recall performance and is associated with a high proportion of recall errors. These findings add new evidence of the influence of emotion on children's verbal short-term memory. Our results are discussed in relation to current semantic and attentional explanations of the emotional enhancement of memory.
