ABSTRACT The Chimeric Face Test (CFT) is a widely used behavioral measure of degree of lateralization for emotion processing. The Pictures of Facial Affect (Ekman, 1976 [ Pictures of facial affect . Consulting Psychologists Press.]) have often been used to create chimeras for this task but have widely been critiqued due to lack of ethnic diversity and small stimuli numbers. In this brief study participants ( N = 45) completed two Chimeric Face Tests, one using the Pictures of Facial Affect and one using the NimStim facial stimuli (Tottenham et al., 2009 [The NimStim set of facial expressions: Judgments from untrained research participants. Psychiatry Research , 168 (3), 242-249]). The laterality scores were compared across measures. The results show the two measures are related; laterality quotients showed a strong correlation between the two tasks. Participants showed a left-visual field bias on both tasks, indicative of a right-hemisphere bias for the processing of emotions. The NimStim Chimeric Face Test however was found to give a more conservative estimate of degree of lateralization. The NimStim Chimeric Face Test is discussed as a valid measure for examining lateralization for emotion processing, The extent to which different versions of the Chimeric Face Test are comparable is discussed.
