Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of emotion. Both words and pictures were used to account for hemispheric differences in language and visuospatial dominance. Response time was faster to emotional pictures than words. Reaction time and speeded accuracy data did not support right hemisphere hypothesis (RHH) or valence hypothesis (VH) in the expected manner. Data suggested emotion caused greater interference under speeded conditions in the right hemisphere (RH) than in the left hemisphere (LH) for strongly right handed individuals. The RH and LH responded differently to language based than to visuospatial information based on handedness. Under unspeeded conditions accuracy data, indicated the RH was more accurate, which supported RHH as hypothesized. SCR had no significant findings.
