Affect identification bias demonstrated with individual chimeric faces.
The current study extends previous findings of a left visual-field bias in chimeric face tasks, by using a new procedure which incorporates chimeric stimuli depicting both positive and negative target affects and requires the identification of affect in individually presented faces. This new procedure is more representative of the types of judgements made in daily social interaction. Results with this new procedure are consistent with previous findings, indicating a significant left visual-field bias for both positive and negative affects in the majority of subjects. Handedness was significantly related to lateralization scores, with dextrals showing greater left visual-field biases than sinistrals. Among sinistrals, a left visual-field bias was noted only for happy chimera.
