“…They perform as if they do not detect the negative emotional expressions, since they mistake them for positive or neu tral expressions. These data are in agreement with those obtained on normal subjects by Dimond and Farrington [ 15]. Using a special optical system of contact lenses which allows involvement of either one or the other hemi sphere, they presented to their subjects dif ferent film sequences (pleasant, humorous, unpleasant, horrific and control) and found an increased arousal (as measured by cardiac responsiveness) when horrific and unpleas ant scenes were processed by the right hemi sphere and concluded: 'The right hemi sphere adds its own emotional dimension which represents the thing perceived as more unpleasant and horrible, and this aligns itself more with the characteristic perception of the depressive patient than with that of the normal individual.…”

The present study investigates the relationship between affective mood state as assessed by self- and hetero-rating scales and information processing of negative versus positive emotional stimuli in unilateral brain-damaged patients. Results show a high positive correlation between depressive mood scores and rating of self-awareness. Left brain-damaged (LBD) patients do not differ significantly from right brain-damaged (RBD) patients on both rating scales. RBD patients mismatch negative emotional stimuli in the nonverbal matching task. Results are discussed with reference to interaction between expression of emotion and cognition. The selective neglect of negative information is interpreted as a more basic emotional impairment.

“…Hemispheric asymmetry has been found for various states of emotion and for the perception of affectively positive or negative stimuli (Davidson, 1984;Dimond & Farrington, 1977). It is not clear whether motivation also displays a lateralized bias similar to that reported for emotion.…”

“…Controversy exists regarding whether the left (Levy, 1983;Tucker, 1981) or the right (Davidson, 1984;Dimond & Farrington, 1977) hemisphere is biased for negative emotion (the reverse bias existing for the opposite hemisphere). If affective word categories significantly alter word recognition, is that effect lateralized?…”

The effects of motivation and affective word content on tachistoscopic recognition were assessed in two experiments. Even with arousal heightened by white noise and with the word exposure slowed (15 vs. 10 msec) per trial, the earlier finding (Ferguson, 1988) was replicated, that under parafoveal viewing hunger, compared to satiation, fails to have a significant effect. Hemispheric asymmetry in affective bias for pleasant and unpleasant words was not found. However, strong evidence was found for significant affective word coding at the lexical stage: for categories with comparable interletter and word frequencies, food words required fewer trials for word recognition, and negatively emotional words required the most trials. In contrast, the reaction times, which likely are more representative of postlexical processing, were fastest for animal words.Previous work by Ferguson (1983Ferguson ( , 1988 has revealed that hunger as an approach motivation facilitates word recognition, but only under foveal, not parafoveal, viewing. Moreover, in two of the foveal-viewing experiments, under separate motivation manipulations of hunger and anxiety, affective word content had a significant effect. When food words, animal words, and negatively emotional words were equated across affective categories for word frequency and interletter associations, food words were most easily recognized, whereas negatively emotional words were least readily recognized. No needrelevance effects were evident, and affective word content had a comparable and significant effect regardless of which type of motivation was examined. Affective word content had less effect with laterally presented stimuli, for both foveal and parafoveal viewing (Ferguson, 1988), possibly due to differential recognition difficulty of left and right off-center word presentation.In the above studies, the stimuli were presented very rapidly (for 10 msec) and repeated until correct word recognition occurred. The task differs in crucial ways from lexical decisions and word-naming studies. This task is akin to the purchasing of information until no more information is needed for correct recognition. Each trial consists of a stimulus exposure that provides a small amount of information. The dependent variable consists of trials to word recognition rather than reaction time (RT), with the two measures yielding somewhat disparate effects. For example, under foveal viewing, hungry subjects required less information purchasing (fewer trials to correct recognition) than did satiated subjects, but the recognized words were not named faster (Ferguson, 1988 In following up the above research concerning motivational influences on word recognition, the present investigation additionally addresses itself to questions concerning affective word content. One question is whether affective word content provides a code for lexical processing (see Chiarello, 1988, on the differentiation of prelexical, lexical, and postlexical processes). If recognition difficulty for off-center parafoveal present...
