“…17 Recall that in contrast with cold cognitions, affective responses are effortless, inescapable, irrevocable, holistic, more difficult to verbalize, yet easy to communicate and to understand. Consider also that the processing of affect is probably an even stronger candidate for the right hemisphere than the processing of pictures (Carmon & Nachson, 1973: Dimond, Farrington, & Johnson, 1976Ley & Bryden, 1979;Milner, 1968;Safer & Leventhal, 1977;Schwartz, Davidson, & Maer, 1975). In the context of this review it is especially interesting (a) that face recognition is superior when the stimuli are pre- 18 Another area of research • in which affect may be implicated (although it had not been so suspected) is the frequency-judgment paradigm.…”

Affect is considered by most contemporary theories to be postcognitive, that is, to occur only after considerable cognitive operations have been accomplished. Yet a number of experimental results on preferences, attitudes, impression formation, and de-_ cision making, as well as some clinical phenomena, suggest that affective judgments may be fairly independent of, and precede in time, the sorts of perceptual and cognitive operations commonly assumed to be the basis of these affective judgments. Affective reactions to stimuli are often the very first reactions of the organism, and for lower organisms they are the dominant reactions. Affective reactions can occur without extensive perceptual and cognitive encoding, are made with greater confidence than cognitive judgments, and can be made sooner. Experimental evidence is presented demonstrating that reliable affective discriminations (like-dislike ratings) can be made in the total absence of recognition memory (old-new judgments).Various differences between judgments based on affect and those based on perceptual and cognitive processes are examined. It is concluded that affect and cognition are under the control of separate and partially independent systems that can influence each other in a variety of ways, and that both constitute independent sources of effects in information processing.

“…Dozens of experiments have investigated the hemispheric laterality of emotional valence and of approach and avoidance behavior. Approach-related behavior (correlated with positive valence) has been lateralized to the left hemisphere, and avoidancerelated behavior (correlated with negative valence) to the right hemisphere, particularly in the frontal lobes (e.g., Ahern & Schwartz, 1979;Cretenet & Dru, 2004;Davidson, 1992;Davidson et al, 1990;Davidson & Fox, 1982;Dimond, Farrington, & Johnson, 1976;Killgore & Yurgelun-Todd, 2007;Maxwell & Davidson, 2007;Natale, Gur, & Gur, 1983;Schiff & Bassel, 1996). 4 This pattern of hemispheric specialization has achieved the status of scientific fact.…”

Do people with different kinds of bodies think differently? According to the body-specificity hypothesis, people who interact with their physical environments in systematically different ways should form correspondingly different mental representations. In a test of this hypothesis, 5 experiments investigated links between handedness and the mental representation of abstract concepts with positive or negative valence (e.g., honesty, sadness, intelligence). Mappings from spatial location to emotional valence differed between rightand left-handed participants. Right-handers tended to associate rightward space with positive ideas and leftward space with negative ideas, but left-handers showed the opposite pattern, associating rightward space with negative ideas and leftward with positive ideas. These contrasting mental metaphors for valence cannot be attributed to linguistic experience, because idioms in English associate good with right but not with left. Rather, right-and left-handers implicitly associated positive valence more strongly with the side of space on which they could act more fluently with their dominant hands. These results support the body-specificity hypothesis and provide evidence for the perceptuomotor basis of even the most abstract ideas.

“…Turning the eyes to the left suggests activity of mechanisms tending supply visual information to the right cerebral hemisphere, indicating a relationship between the right brain and emotion [7,8]. Furthermore, in terms of brain function, one study of emotional perception used eye movements across a screen to demonstrate that the right hemisphere plays a dominant role in retention and recall of emotionally related facial expressions, with a higher frequency of eye movements to the left during such tasks [9].…”

Effects of Emotionally Affect Adult and Baby’ Photographs in Healthy Controls and Schizophrenic Patients Evaluating by Exploratory Eye Movements

Humans obtain a particularly large amount of information for adapting to their environment visually as opposed to other types of sensory input. Specific information is selected from a wide variety of visual stimuli, and then processed to guide behavior. Affection and emotion are critical elements of human relationships: generally, negative emotions impair quality of life, while positive emotions make life pleasurable. Affective stimuli have been shown to influence event-related potentials such as P300 components [1,2] and potentials related to eye movements [3][4][5]. The relationship between mother and baby, in particular, is of fundamental importance in the development of cognitive function and emotion [6]. Schwartz et al. [7] compared responses of healthy adults between emotional and none-motional figure Kurume Medical Journal, 58, 27-33, 2011 Summary: The relationship between mother and baby is of fundamental importance in the development of cognitive function and emotion. In this study we investigated the effects of affective photographs of a mother and baby (crying or smiling faces) and other stimuli (neutral mother or baby faces) on visual cognitive function in schizophrenic patents. We recorded exploratory eye movements in 22 healthy controls and 22 age-matched schizophrenic patients. Total number of right and left field gaze points (right TNGP, left TNGP) in the visual fields were determined using an eye-mark recorder as subjects viewed affectively charged or neutral photographs (crying, smiling or neutral faces). Left TNGP for all mother photographs (crying, smiling or neutral) were significantly larger in controls than patients, and right TNGP for neutral mother photographs were significantly larger in controls than in patients. Right TNGP for photographs of smiling babies were significantly larger in controls than patients, and left TNGP for photographs of both smiling and crying babies were significantly larger in controls than patients. Within the patient group, right TNGP were significantly larger than left TNGP for all mother photographs (crying, smiling or neutral). Left TNGP for photographs of mothers and babies correlated negatively with negative symptom scores. These results suggest that exploratory eye movements when viewing emotionally laded twin stimuli such as photographs of a mother and baby are a useful marker of visual cognitive function in both healthy controls and schizophrenic patients.
