Left hemisphere specialization for response to positive emotional expressions: a divided output methodology.

Results support the view that response preparation to positive emotional stimuli is left lateralized and weaken the case for left hemisphere dominance for positive emotions.

Right hemisphere lateralization for emotion in the human brain: interactions with cognition

The data support the hypothesis that the right hemisphere has a special role in emotion in the intact brain, and that predictable patterning of hemispheric activity can occur when specific combinations of cognitive and affective processes interact.

Differing emotional response from right and left hemispheres

The basis of this research is that the two hemispheres can differ in their vision of the world and that each in some respects formulates its own separate and distinct emotional vision of what it sees.

Laterlized facial muscle response to positive and negative emotional stimuli.

The results are consistent with the hypothesized specialization of the left and right cerebral hemispheres for the mediation of positive and negative emotions, respectively.

Emotions are expressed more intensely on the left side of the face.

Hemispheric asymmetry in the control over emotional expression in the face is indicated in the form of left-side and right-side composites.

Ear differences in evaluating emotional tones of voice and verbal content.

Two experiments are presented in which lateralization of monaural, auditory input affected the evaluation of verbal passages, and subjects who listened on the right ear were more accurate in rating both cues.
