Background Introduction: Emotion facilitates word recognition under adverse acoustic conditions. We use an auditory emotional paradigm to evaluate the ability to distinguish words from irrelevant random stimuli, elucidating its neural correlates. Secondarily, we evaluate the impact of schizotypy traits on this capacity.Methods Methods: 25 participants, undertook an fMRI task, indicating whether they recognized words, through a response box. 20 audio files of emotionally negative words and 20 neutral words were presented. Word intelligibility was manipulated merging the audio files with white noise, resulting in 3 levels (pure words, degraded words, and noise). We measured schizotypy with the O-LIFE scale.Results Results: A 2x3 factorial ANOVA was performed with emotion (neutral or negative) and intelligibility (pure word, degraded word and noise) as factors. There was an interaction between emotion and intelligibility [F(2,44)=23,89,p
