Childhood trauma is associated with perceived stress and hair cortisol levels characterized by the BDNF Val66Met genotype and sex Open
Introduction Childhood trauma increases the risk of mental disorders by affecting both psychological and physiological stress responses in adulthood, including perceived stress and long-term hypothalamic-pituitary-adrenal (HPA) axis activi…

Eye tracking based clustering using the Korean version of the reading the mind in the eyes test Open
This study applies eye-tracking paradigms to cluster data based on participants' gaze patterns, while performing the Korean version of the Reading the Mind in Eyes Test, and to investigate whether there were differences in the neurocogniti…

Epigenetic modulation of social cognition: exploring the impact of methylation in brain-derived neurotrophic factor and oxytocin receptor genes across sex Open
Social cognition, which ranges from recognizing social cues to intricate inferential reasoning, is influenced by environmental factors and epigenetic mechanisms. Notably, methylation variations in stress-related genes like brain-derived ne…

Epigenetic Modulation of Social Cognition: Exploring the Impact of Methylation in Brain-Derived Neurotrophic Factor and Oxytocin Receptor Genes Across Sex Open
Background: Social cognition, which ranges from recognizing social cues to intricate inferential reasoning, is influenced by environmental factors and epigenetic mechanisms. Notably, methylation variations in stress-related genes like brai…

Association of hair cortisol concentration with brain‐derived neurotrophic factor gene methylation: The role of sex as a moderator Open
Hair cortisol concentration (HCC) reflects the long‐term activity of the hypothalamus‐pituitary‐adrenal (HPA) axis in response to stress. Brain‐derived neurotrophic factor DNA methylation (BDNF DNA M ) may affect HCC, and sex and Val66Met …

Relationship of neurocognitive ability, perspective taking, and psychoticism with hostile attribution bias in non-clinical participants: Theory of mind as a mediator Open
Objectives Hostile attribution bias is reportedly common from non-clinical population to those with serious mental illness, such as schizophrenia, and is known to be closely related to theory of mind (ToM). This study aimed to investigate …

Empathy and Theory of Mind in Ultra-High Risk for Psychosis: Relations With Schizotypy and Executive Function Open
Objective While recent studies have found deficits in theory of mind (ToM) skills in individuals at ultra-high risk (UHR) for psychosis, empathic tendencies in these subjects remain unclear. The presence of high schizotypy and compromised …

Empathic Tendency and Theory of Mind Skills in Young Individuals with Schizophrenia: Its’ Associations with Self-Reported Schizotypy and Executive Function Open
Objectives\nSocial function deficit is known as a core feature of schizophrenia. This study aimed to investigate differences in empathic tendencies and theory of mind (ToM) skills between healthy controls and young individuals with schizop…

“Reading the Mind in the Eyes Test”: Translated and Korean Versions Open
Objective The Reading the Mind in the Eyes Test (RMET) was developed by using Caucasian eyes, which may not be appropriate to be used in Korean. The aims of the present study were 1) to develop a Korean version of the RMET (K-RMET) by usin…

Reading the Mind in the Eyes Test: Relationship with Neurocognition and Facial Emotion Recognition in Non-Clinical Youths Open
Objective The Reading the Mind in the Eyes Test (RMET) is a common measure of the Theory of Mind. Previous studies found a correlation between RMET performance and neurocognition, especially reasoning by analogy; however, the nature of thi…

Impaired Facial Emotion Recognition in Individuals at Ultra-High Risk for Psychosis and Associations With Schizotypy and Paranoia Level Open
UHR individuals exhibited inaccuracy and negative bias of facial emotion recognition. Furthermore, schizotypy scores were associated with inaccuracy but not with negative bias of facial emotion recognition. Paranoia level was correlated wi…
