Alexithymia, a personality construct marked by difficulties in processing one's emotions, has been linked to the altered activity in the anterior cingulate cortex (ACC). Although longitudinal studies reported sex differences in alexithymia, what mediates them is not known. To investigate sex-specific associations of alexithymia and neuronal markers, we mapped metabolites in four brain regions i...

Objective: Depression is common among adult survivors of child sexual abuse (CSA), but the intervening processes responsible for this outcome have not yet been fully delineated. The present study investigated the mediating role of perceived parental emotion socialization and alexithymia (difficulties identifying and describing feelings) in explaining the link between CSA and adult depressive sy...

Relationships among alexithymia, personality disorders, and higher-order psychopathological and interpersonal dimensions were examined in 199 college students and a close relative of each. Alexithymia, the difficulty to express and identify emotions, was measured by the Observer Alexithymia Scale (OAS; [Haviland, M. G., Warren, W. L., & Riggs, M. L. (2000). An observer scale to measure alexithy...

While alexithymia, or difficulties identifying and describing affect, has been commonly observed in schizophrenia, little is known about its causes and correlates. To test the hypothesis that deficits in emotion identification and expression result from, or are at least related to, deficits in neurocognition and affective symptoms, we assessed alexithymia using the Toronto Alexithymia Scale (TA...

We investigated the moderating impact of the personality construct alexithymia on the ability of younger and older adults to control the recall of negative and neutral material. We conducted two experiments using the directed forgetting paradigm with younger and older adults. Participants studied negative (Experiment 1) or neutral (Experiment 2) words. Participants were instructed to forget the...

Alexithymia is characterized by deficits in emotional self-awareness. A number of previous studies have revealed impaired emotional self-awareness in schizophrenia. Although the pathology of schizophrenia is thought to involve disrupted white matter integrity, its relationship with alexithymia remains unclear. The present study investigated associations between alexithymia and white matter inte...

The ability to represent mental states (theory of mind [ToM]) is crucial in understanding individual differences in social ability and social impairments evident in conditions such as autism spectrum disorder (ASD). The Reading the Mind in the Eyes Test (RMET) is a popular measure of ToM ability, validated in part by the poor performance of those with ASD. However, the RMET requires recognition...

Objective: Alexithymia is increasingly recognized in a number of psychiatric disorders, but a possible relationship between alexithymia and adult attention-deficit/hyperactivity disorder (ADHD) has not been studied. It is not known if psychostimulants decrease symptoms of both ADHD and alexithymia. This relationship is examined in a small naturalistic and longitudinal study. Participants: Ten c...

Background: Previous studies have reported the high rate of alexithymia in medical and psychological disorders along with the role of emotional expressiveness practices in terms of different aspects of health. The aim of this study was to compare the alexithymia and emotional expressiveness in patients with coronary heart disease and healthy people. Materials and Methods: In this ex post facto ...

BACKGROUND Alexithymia is a personality trait characterized by difficulties in the cognitive processing of emotions (cognitive dimension) and in the experience of emotions (affective dimension). Previous research focused mainly on visual emotional processing in the cognitive alexithymia dimension. We investigated the impact of both alexithymia dimensions on electrophysiological responses to emo...
