The effect of laughter expression modulation on emotional experience in 4 to 10 year-old children

Abstract

According to the literature, in adulthood, facial expression control unconsciously generates a congruent change in emotional experience (facial feedback). Although only a few studies have been conducted on this phenomenon with children, it is to be expected that the strength of the link between facial expression and emotional experience will diminish with age, and consequently, that the facial feedback effect will decrease with age. In order to test this hypothesis, we used an emotional induction paradigm (based on funny video-clips) with an expressive change paradigm (i.e., free expression vs. laughter restriction vs. laughter exaggeration). The emotional experience of 4–10-year-old children was assessed a posteriori based on analyses of their narratives about the video-clips. Results indicated that the children benefited from a facial feedback effect on their emotional experiences without an age effect. They are discussed in the light of the literature on emotional regulation and emotional development.
