We used facial EMG to examine reactions to the attractiveness of natural (faces) and artificial (abstract patterns) stimuli under long and short presentation durations. Attractive stimuli produced strong activations of the M. zygomaticus major muscle, indicating positive affective reactions; and unattractive stimuli produced strong activations of the M. corrugator supercili muscle, indicating negative affective reactions. Fluency effects, indicated by stronger activations of the M. zygomaticus major under the longer presentation duration were, however, only found for the abstract patterns. Moreover, the abstract patterns also were associated with more consistent activations over time than the faces, suggesting differences in the processes …
