Some distinctions can be crucial to explain the differences between both studies. Stimuli used by Lo (2008) were presented during 1 min, while in our study emoticons were presented during 500ms. This implies that when participants have less time to respond to select the mood of the message,they do it with less deliberated inference processing. Longer times to select responses could facilitate a reflexive analysis for judging the mood; while we obtained results of earliest stages of mood detection process. Additionally, Lo (2008) instructed the participants to indicate the degree of sadness or happiness perceived on each messages. Our responses were dichotomic alternatives, where participants had to indicate only if they perceived a good or bad mood. This difference is related with the previous point (i.e., the deliberation),because,to indicate the degree of a specific emotion intensity, implies analyzing the stimuli which is a more complex process. In our experiment,we did not take the level of perceived emotional intensity, but, with the previous validation of stimuli, we controlled that the observed valence effects in ambiguous messages,were not due to differenceson emotional intensity.
