A dual-process model is suggested for the processing of words with emotional meaning in the cerebral hemispheres. While the right hemisphere and valence hypotheses have long been used to explain the results of research on emotional stimulus processing, including nonverbal and verbal stimuli, data on emotional word processing are mostly inconsistent with both hypotheses. Three complementary lines of research data from behavioral, electrophysiological, and neuroimaging studies seem to suggest that both hemispheres have access to the meanings of emotional words, although their time course of activation may be different. The left hemisphere activates these words automatically early in processing, whereas the right hemisphere gains access to emotional words slowly when attention is recruited by the meaning of these words in a controlled manner. This processing dichotomy probably corroborates the complementary roles the two hemispheres play in data processing.

“…Thus, for this experiment, response measures seemed to be driven by the VF of the test stimulus. However, the LH advantage for word reading makes it difficult to determine the extent to which this pattern might have been dominated by perceptual-processing asymmetries, which, in some cases, can mask more subtle effects of memory (Nagae & Moscovitch, 2002).…”

Hemispheric asymmetries in the time course of recognition memory

Hemispheric specialization has been studied extensively within subfields ranging from perception to language comprehension. However, the study of asymmetries for basic memory functions-an area that holds promise for bridging these low-and high-level cognitive domains-has been sporadic at best. We examined each hemisphere's tendency to retain verbal information over time, using a continuous recognition memory task with lateralized study items and central test probes. We found that the ubiquitous advantage of the left hemisphere for the processing and retention of verbal information is attenuated and perhaps even reversed over long retention intervals. This result is consistent with theories that propose differences in the degree to which the hemispheres maintain veridical versus semantically transformed representations of the input they receive.

“…Reuter-Lorenz and Davidson, 1981). However, lexical decision experiments have often failed to find such an interaction between the valence of a stimulus word and the processing hemisphere (Graves et al, 1981;Nagae & Moscovitch, 2002). Based on known effects of an individual's hemispatial bias on cognitive processing (Mohr et al, 2003;Taylor et al, 2002) and emotional attitudes (Drake and Ulrich, 1992), we assessed our subjects' inclination to bisect a line to the left or right of its veridical midpoint.…”

“…In some studies, emotional words were better recognized in the left visual field (LVF) / RH, irrespective of valence (Graves et al, 1981). Other authors have found a perceptual identification advantage for the right visual field (RVF), reflecting the dominance of the LH for linguistic processing (Nagae & Moscovitch, 2002). Because of these inconsistencies, valence theories are usually discussed as only one of several alternatives in the conceptual analysis of hemispheric differences in emotional processing (see Demaree et al, for a comprehensive overview).…”

Emotion and space: lateralized emotional word detection depends on line bisection bias

Emotion and space: lateralized emotional word detection depends on line bisection bias Tamagni, C; Mantei, T; Brugger, P There is converging evidence, from various independent areas of neuroscience, for a functional specialization of the left and right cerebral hemispheres for positive and negative emotions, respectively ("valence theory" of emotional processing). One subfield, however, has produced mixed results, i.e. work on the detection of parafoveally presented positively or negatively emotional words by healthy subjects. Right or left visual field advantages were described and interpreted as reflecting the superiority of either the left hemisphere (LH) for linguistic material, or of the right hemisphere (RH) for highly emotional stimuli. Here we show that 48 healthy, right-handed participants' performance on a lateralized lexical decision task depends on their individual inclination to bisect a line to the left or right of the objective center. Only those with a bisection bias to the right showed the LH advantage for word detection known from the neuropsychological literature. Negative emotional words were processed with comparable accuracy in the two visual fields. However, a recognition advantage for negative over positive emotional words was found exclusively for those participants with a leftward line bisection bias. These results suggest that in work on functional hemispheric differences state variables like stimulus lateralization and word emotionality may be less decisive than the trait variable of lateral hemispatial attention. We propose a cautious reconsideration of the concept of "hemisphericity," which once emphasized individual differences in baseline hemispheric arousal, but was later dismissed in a reaction to oversimplifications in popular science accounts.
