Multidimensional schizotypy and embodied emotions.

Background: Disembodiment and socio-emotional deficits are core features of the schizophrenia spectrum from the prodromal stages to chronic illness. A recent study documented anomalous emotional embodiment in individuals with schizophrenia. Although bodily self disturbances have been shown to precede and predict psychosis onset in at-risk populations, the etiology of anomalous emotional embodiment remains largely unexplored.

Quadratic Relationship Between Alexithymia and Interoceptive Accuracy, and Results From a Pilot Mindfulness Intervention.

Alexithymia, or a reduced ability to label and describe one's emotions, is a transdiagnostic construct associated with poor psychosocial outcomes. Currently, the mechanisms underlying affective deficits associated with alexithymia are unclear, hindering targeted treatment delivery. Recent research suggests deficient interoceptive awareness, or reduced awareness of one's internal bodily state, may be key in the etiology of alexithymia.

Exploring individual and group differences in latent brain networks using cross-validated simultaneous component analysis.

Component models such as PCA and ICA are often used to reduce neuroimaging data into a smaller number of components, which are thought to reflect latent brain networks. When data from multiple subjects are available, the components are typically estimated simultaneously (i.e.

Anomalous Bodily Maps of Emotions in Schizophrenia.

Objective: Embodied emotions arise from interoceptive and somatosensory processes, and are essential to the development of a stable sense of self. Emotional embodiment is therefore inherently interwoven with our sense of bodily self-awareness, and allows us to navigate complex social situations. Given that the core feature of schizophrenia (SZ) is characterized by the presence of bodily self-disturbances and social-emotional deficits, we hypothesized that embodiment of emotion would be disrupted in SZ.

Affect labeling and other aspects of emotional experiences in relation to alexithymia following standardized emotion inductions.

Alexithymia is associated with increased risk for mental and physical health disorders but available assessments rely exclusively on self-report. The major aim of the current study was to develop and implement a performance-based task designed to characterize and quantify the relationship between one's description of emotional experience and self-reported alexithymia. Specifically, we examined performance-based measures of affect labeling of one's own emotions, emotional granularity and dialecticism.
