Each practic movement was assessed for accuracy and motor execution. Left-brain-damaged patients were significantly impaired on these tasks relative to right-damaged patients and controls. When emotional context was provided, apractic performance improved significantly.

In this preliminary investigation, emotionally laden slides were used to elicit discourse from right brain-damaged (RBD), left brain-damaged (LBD), and normal control (NC) subjects. New techniques were developed to examine the ability of these subjects to express emotion in words; formalistic and pragmatic analyses of the discourse were conducted. RBDs, relative to NCs and LBDs, were less successful in using words to convey emotion and produced words of lower emotional intensity. LBD aphasics, despite their linguistic deficits, were comparable to NCs in conveying emotional valence. The data tend to support the speculation that the right hemisphere is dominant for lexical expression of emotion. This study has implications for the neuropsychological investigation of language, emotion, and the brain.

This question was addressed by testing 40 patients with unilateral stroke (20 with left-brain and 20 with right-brain damage) and 20 healthy control participants for recall and recognition of 48 target words. During encoding, emotional and nonemotional words were either presented in sentences (read condition) or used to form sentences (generate condition). Both word emotionality and generative processing improved memory performance in all groups. The authors suggest that a similar influence (i.e., cognitive activation) underlies both of these memory-enhancing effects, although the putative origins of the 2 effects are quite different. Neuropsychological underpinnings and clinical implications of these phenomena are discussed.

Hypotheses pertaining to laterality and emotion were tested. More specifically, we were interested in whether the right hemisphere is dominant for verbally-presented emotion. In addition, we examined whether emotional content improves the performance of patients with left brain damage (LBD) and language deficits. Subjects were 11 patients with right brain damage (RBD), 10 patients with LBD, and 15 normal control adults. The subject groups did not differ significantly on demographic or basic cognitive variables; the patient groups were similar on neurologic variables. Parallel emotional experimental and nonemotional control tasks included word identification (or recognition), sentence identification, and word discrimination. There were eight emotional categories (e.g., happiness) and eight nonemotional categories (e.g., vision). A significant interaction among Group, Condition, and Task revealed that patients with RBD were significantly impaired relative to patients with LBD and normals within the emotional condition, particularly for the identification tasks. Furthermore, the performance of patients with LBD and language deficits was improved by emotional content for the sentence identification task. These findings suggest that the right hemisphere has a unique contribution in the identification of lexical emotional stimuli. Implications for rehabilitation of patients with LBD and language deficits and patients with RBD by means of emotion-based strategies are discussed.
