In the present study,we designed an experiment to investigate the influence of the valence of the text in the influence of the emoticons to disambiguate messages on the inference of sender’s mood. Using an emotional decision task in an affective congruence paradigm, we presented text-based messages with positive and negative valence,followed by typographic emoticons which could have positive and negative valence. Our aim was to analyze the influence of emoticon valence on the capacity to infer the interlocutor’s mood and on the reaction time(RT)in order to observe if the emoticon is the prioritized source of information, or if it depends on the affective contextual information in which it appears.
