Some methodological problems in the study of the relationships between emotions and cerebral dominance

The findings of studies involving brain-damaged patients and those with normal subjects are considered separately in a review of the most important investigations that have led to the hypothesis that the right hemisphere is dominant for various aspects of emotional behavior. This paper examines some of the methodological problems encountered in studies of laterality of emotions, again looking at investigations of brain-damaged patients and of normal subjects. Future directions for research into emotional lateralization are suggested.
