The most prominent features of alexithymic people are a demonstrated reduction in the ability to identify and to describe their own feelings. In recent years, these characteristics have been related to a functional disturbance of the right cerebral hemisphere. This should result in a number of other observable effects. The present study investigated whether high and low alexithymics from a nonclinical population differed in the degree of leftward perceptual bias on chimeric tasks. The chimeras… 

Specific brain processing of facial expressions in people with alexithymia: an H2 15O-PET study.

It is suggested that people with alexithymia process facial expressions differently from people without alexITHymia, and that this difference may account for the disorder of affect regulation and consequent peculiar behaviour in people with the disease.

An investigation of facial emotion recognition impairments in alexithymia and its neural correlates

Alexithymia Is Related to the Need for More Emotional Intensity to Identify Static Fearful Facial Expressions

Results showed that HA needed more emotional intensity than LA to identify static fearful – but not happy or disgusted – faces, and no evidence was found that alexithymia affected the identification of dynamic EFEs.

Facial emotion recognition and alexithymia in adults with somatoform disorders

The deficit in facial emotion recognition observed in the patients with SFD was most likely a consequence of concurrent alexithymia, which could plausibly have a negative influence on these individuals' social functioning.

Alexithymia, Not Autism, Predicts Poor Recognition of Emotional Facial Expressions

Findings accord with the hypothesis that the emotional symptoms of autism are in fact due to co-occurring alexithymia and that existing diagnostic criteria may need to be revised.

Facial emotion recognition and alexithymia in adults with somatoform disorders

It is suggested that the deficit in FER observed in the patients with SFD was most likely a consequence of concurrent alexithymia, and neither depression nor anxiety was significantly related to emotion recognition accuracy, suggesting that these variables did not contribute the emotion recognition deficit.

Alexithymia is associated with attenuated automatic brain response to facial emotion in clinical depression

Alexithymia, gender, and hemispheric functioning.

It is concluded that deficiencies in right hemisphere function and interhemispheric transfer may contribute to alexithymia in men, but not in women.

The physiological response to implicit and explicit fear faces in alexithymia

Alexithymia is a form of disordered emotional processing associated with psychiatric illness and poor treatment outcomes. Its hallmarks are difficulty identifying, representing and evaluating

Alexithymia and impaired facial affect recognition in multiple sclerosis

Data from a dedicated neuropsychological assessment of emotion processing in multiple sclerosis patients provide evidence for deficits in the recognition of emotional face expressions and emotional introspection.

Results show that alexithymics were comparable to controls in judgments of the impact of provocative slides and in their ability to label posed expressions and suggest that deficits in nonverbal expression are central to the phenomenon.

Alexithymia and the recognition of facial expressions of emotion.

The results suggest the presence of deficits in the perception of nonverbal emotion in alexithymia, which was significantly less able to recognize facial expressions of emotions than the low alexithsymia group.

Abstract This study examined the relationship between alexithymia and (a) hemis-patial bias; (b) the accuracy of interpreting emotion-relevant information; and (c) the style of interpreting

The role of the right hemisphere in emotional communication.

It is found that RHD subjects performed normally in their ability to infer the emotion conveyed by sentences describing situations, but RHD patients were impaired in relation to both LHD and NC in the capacity to judge the emotional content of sentences depicting facial, prosodic, and gestural expressions.

Relationship between conjugate lateral eye movements and alexithymia.

It is suggested that alexithymia is associated with left cerebral lateralization, and the hypothesis that a lexithymic characteristics reflect a variation in brain organization is supported.
