Hemispheric differences in split-brain monkeys viewing and responding to videotape recordings.
Eight split-brain monkeys were tested for hemispheric differences in their viewing of and responses to colored videotape recordings of monkeys, people, animals, and scenery. The number of facial expressions elicited from the right hemisphere was significantly greater than the number made when using the left hemisphere. Monkeys also tended to look longer when viewing with their right hemispheres than when viewing with the left.
