TL;DR
The data support the hypothesis of differential hemispheric specialization for positive and negative emotion and demonstrate opposite patterns of asymmetry in affect perception for inverted and non-inverted left-handers.
Abstract
Right-handers and inverted and non-inverted left-handers viewed emotional expressions in one hemifield and, simultaneously, a neutral expression of the same poser in the other hemifield. Subjects were required to identify the side containing the affective face. Happy faces with open (i.e. salient) and closed mouth smiles and sad faces were used as stimuli. For right-handers and inverters reaction time was faster to right hemifield presentations for happy faces and to left hemifield presentations for sad faces. Non-inverters showed the reverse pattern. The saliency of the happy expressions had no effect on the magnitude and direction of asymmetry for any group. The data support the hypothesis of differential hemispheric specialization for positive and negative emotion and demonstrate opposite patterns of asymmetry in affect perception for inverted and non-inverted left-handers.

The depressivecatastrophic reactions of the left brain-damaged patients were found chiefly in subjects with severe aphasia, and appeared generally after repeated failures in verbal communication, and seemed due, as Goldstein argued, to the desperate reaction of the organism, confronted with a task that it cannot face.

A general model of hemispheric asymmetry in the regulation of emotion is presented, and the findings are congruent with studies of the effects of unilateral brain insult on mood.

ificant left visual field superiorities for both character and emotional expression recognition were found and are consistent with experimental and clinical literature which has indicated a right hemispheric superiority for face recognition and for processing emotional stimuli.

The pattern of latencies for the different visual field-response hand conditions supported a model of lateral specialization in which the specialized hemisphere normally processes both directly-received and interhemispherically- transferred stimuli.

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.

This author made the important observation that it is possible to interfere with the functional activity of only the dominant hemisphere, and the only technique specifically elaborated for establishing the side of cerebral dominance seems to be that of Wada.

It is concluded that the right hemisphere acts as the dominant trigger to unpleasant emotional experience and that probably a division of labour for the production of different types of emotion exists between the two hemispheres.

The perception of emotion in verbal and facial expression, and the spontaneous production of conversational speech were studied in patients with unilateral focal excisions of frontal, temporal, or parieto-occipital cortex, suggesting the nature of the behavioral stimulus as well as the locus and side of damage must be considered in the study of the neural basis of affective behavior.

The observations seem to answer many questions concerning the issue of whether the mechanisms of consciousness can be split and doubled by split‐brain surgery and suggest that the special nature of human conscious experience is closely tied to linguistic processes.

It is proposed that both writing postures are directly controlled by the language-dominant hemisphere via Levy and Reid (1978), which demonstrated that the hemisphere (left or right) which is dominant for verbal and spatial functions in a given individual can reliably be predicted by knowledge of that person's hand preference and posture for writing.
