Background: the existence of specific effects of emotion on text comprehension in adults has been experimentally verified. However, there is no information regarding adolescents, which is relevant for the design of interventions. Objective: this research study aims to assess whether dimensionallyconceptualized emotional states (valence, arousal and dominance) affect the comprehension and retrieval of written texts in adolescents. Method: following instrument validation, three experiments (n = 468) were performed. They consisted in inducing emotions which differed in one dimension (valence, arousal or dominance) and kept others the same, in order to assess the role of each dimension on comprehension and retrieval processes (i.e., positive vs. negative valence; stable arousal and dominance in experiment 1). Results: the results indicate that valence has an impact on text comprehension and ...
