Facial approach signals in speechreading were studied in three experiments. Experiment 1 investigated effects on speechreading performance of different emotional content (sad and happy) in sentences combined with facial expression. The experiment also investigated the effect of script information on speechreading of emotionally charged sentences. In Experiment 2 the effect of emotional sentences on speechreading performance was investigated when no or very limited script information was given. Happy sentences were superior to sad sentences, except in the sad script where no difference between sad and happy was found. Experient 3 investigated the effect of articulation (overarticulation vs. underarticulation) on speechreading of emotional sentences. Happy sentences were again generally superior to sad sentences. As happy sentences were superior to sad sentences both when overarticulated and underarticulated the superiority of the happy sentences was explained in light of the approach hypothesis.
