Religious and mystical experiences might correlate with the interaction between the two brain hemispheres. This study aimed to determine whether there is any hemispheric specialization in processing religious stimuli and any difference in hemispheric asymmetry patterns between participants with high and low religious attitudes. Visual half-field presentation was used to measure the response of the hemispheres behaviorally. Religious and neutral photographs were presented either into the right visual field/left hemisphere (RVF/LH) or left visual field/right hemisphere (LVF/RH). The participants were asked to rate the feeling evoked by each photograph on a 7-point Likert scale (1 = very negative, 7 = very positive). The response time results indicated a right hemispheric superiority in processing speed of the stimuli; however, no hemispheric specialization was found for evaluation of the religious stimuli. The low religious participants showed LVF/RH advantage in reaction time (RT) for both religious and neutral stimuli, while the high religious participants showed an RVF/LH advantage for the religious stimuli. The findings are discussed in the context of approach-withdrawal and valence hypothesis.
