“…Overall, right hemisphere advantage in the processing of EFE seems well established (Adolphs et al, 2000;Bowers et al, 1991;Nakamura et al, 1999;Streit et al, 1999Streit et al, , 2000. The right hemisphere seems especially implicated in the processing of negative emotions (Adolphs et al, 2000;Davidson, 1992;Davidson and Fox, 1982;Grafman et al, 1986;Ley and Bryden, 1979;Mandal and Singh, 1990;McDowell et al, 1994;Natale et al, 1983;Sackeim et al, 1978;Suberi and McKeever, 1977), whereas positive emotions seem to be prefrentially processed by the left hemisphere (Harrison and Gorelczenko, 1990;Reuter-Lorenz et al, 1983;Suberi and McKeever, 1977).…”

Objective: Emotional facial expression (EFE) decoding skills play a key role in interpersonal relationships. Decoding errors have been described in several pathological conditions, including alcoholism. The aim of this study was to investigate whether EFE decoding skill deficits persist after abstention from alcohol of at least 2 months. Method: Alcoholic patients abstinent for at least 2 months (n = 25) were compared with 25 recently detoxified patients and with 25 normal controls matched for age, gender and educational level. Subjects were presented with 40 photographs of facial expressions portraying happiness, anger, sadness, disgust and fear. Each emotion was displayed with neutral, mild, moderate and strong emotional intensity. Each facial expression was judged successively on eight scales labeled happiness, sadness, fear, anger, disgust, surprise, shame and contempt. For each scale, subjects rated the estimated intensity level. A complementary scale assessed the selfestimated difficulty in performing the task. Results: Recently detoxified alcoholics were significantly less accurate than controls, making more EFE labeling errors and overestimating the intensity of the portrayed emotions. Deficits in decoding accuracy for anger and disgust were present in mid-to long-term abstinent patients; intensity overestimation was present in the former and absent in the latter. Conclusions: Deficits in decoding accuracy for anger and disgust, and to a lesser degree sadness, persist with an abstinence of 2 months and beyond. Right frontotemporal regions and cingulate could be implicated. These deficits may contribute to the social skills deficits frequently encountered in alcoholic patients. (J. Stud.

“…In accordance with this notion, a number of investigations have suggested an RH bias in the perception of negative facial expressions (e.g., Fox, 2002;Mogg & Bradley, 2002;Adolphs, Damasio, Tranel, & Damsio, 1996;Johnsen & Hugdahl, 1991;Mandal & Singh, 1990); and negative relative to positive facial expressions (Nicholls, Ellis, Clements, & Yoshino, 2004;Jansari, Tranel, & Adolphs, 2000;Workman, Peters, & Tayler, 2000;Davidson, Mednick, Moss, & Saron, 1987;Reuter-Lorenz & Davidson, 1981).…”

Unattended Facial Expressions Asymmetrically Bias the Concurrent Processing of Nonemotional Information

Planned and reflexive behaviors often occur in the presence of emotional stimuli and within the context of an individual's acute emotional state. Therefore, determining the manner in which emotion and attention interact is an important step toward understanding how we function in the real world. Participants in the current investigation viewed centrally displayed, task-irrelevant, face distractors (angry, neutral, happy) while performing a lateralized go/no-go continuous performance task. Lateralized go targets and no-go lures that did not spatially overlap with the faces were employed to differentially probe processing in the left (LH) and right (RH) cerebral hemispheres. There was a significant interaction between expression and hemisphere, with an overall pattern such that angry distractors were associated with relatively more RH inhibitory errors than neutral or happy distractors and happy distractors with relatively more LH inhibitory errors than angry or neutral distractors. Simple effects analyses confirmed that angry faces differentially interfered with RH relative to LH inhibition and with inhibition in the RH relative to happy faces. A significant three-way interaction further revealed that state anxiety moderated relations between emotional expression and hemisphere. Under conditions of low cognitive load, more intense anxiety was associated with relatively greater RH than LH impairment in the presence of both happy and threatening distractors. By contrast, under high load, only angry distractors produced greater RH than LH interference as a function of anxiety.

“…Left and right brain lesioned deaf signers have revealed unique patterns of spared and impaired functions relating to linguistic and affective face processing (Corina et al, 1999). Results suggest, among other things, that a neural dissociation exists between linguistic and nonlinguistic cognitive processing (i.e., grammaticized and affective face processing respectively) (Corina, 1989;Corina et al, 1999;Kubota et al, 2003;Mandal and Singh 1990).…”

Linguistic Ability and Mental Health Outcomes Among Deaf People With Schizophrenia

Cognition has become prominent in the study of schizophrenia because of its importance for understanding the etiology of the illness and its consequences for living independently. For people with schizophrenia who are also deaf, investigations of cognition and schizophrenia are infrequent. This study examines the role of linguistic ability in relation to cognition, social cognition, and functional outcome among deaf adults with schizophrenia or schizoaffective disorder. The primary finding is that linguistic ability is positively and significantly associated with functional outcome above and beyond the contribution of cognition and social cognition. A younger age of sign language acquisition is significantly associated with superior linguistic ability, but did not moderate the effect of linguistic ability on other domains. Opportunities for deaf mental health consumers to participate in sign language enrichment programs and communicate with other skilled signers may be useful additions to standard psychiatric rehabilitation programming. More research is needed to clarify the consequences of deafness with regards to schizophrenia especially as it relates to language, vision, and symptoms.
