Altered upright face recognition and presence of face inversion effect in temporal lobe epilepsy: An event-related potential study.

Aim: Facial recognition can be assessed by examining an event-related potential component, namely the N170. The amplitude of the N170 is larger in response to inverted faces than to upright faces. To examine facial processing in patients with temporal lobe epilepsy (TLE), we investigated the amplitude of the N170, the face inversion effect, and the association between social functioning and face-specific configuration processing.

Affective temperaments play an important role in the relationship between childhood abuse and depressive symptoms in major depressive disorder.

Previous studies have shown that various factors, such as genetic and environmental factors, contribute to the development of major depressive disorder (MDD). The aim of this study is to clarify how multiple factors, including affective temperaments, childhood abuse and adult life events, are involved in the severity of depressive symptoms in MDD. A total of 98 participants with MDD were studied using the following self-administered questionnaire surveys: Patient Health Questionnaire-9 measuring the severity of depressive symptoms; Life Experiences Survey (LES) measuring negative and positive adult life events; Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego auto-questionnaire (TEMPS-A) measuring affective temperaments; and the Child Abuse and Trauma Scale (CATS) measuring childhood abuse.

Psychological effects of disaster relief activities on Japan ground self-defense force personnel following the 2011 great east Japan earthquake.

Objective: Disaster relief workers are potentially exposed to severe stressors on the job, resulting in a variety of psychological responses. This study aims to clarify the psychological effects of disaster relief activities on Japan Ground Self-Defense Force (JGSDF) personnel following the 2011 Great East Japan Earthquake.

Method: A self-report questionnaire was administered to 606 JGSDF personnel one month after completing the disaster relief mission.

Altered face inversion effect and association between face N170 reduction and social dysfunction in patients with schizophrenia.

Objective: There is accumulating evidence that schizophrenics may have deficits in facial recognition, which has been related to disease-specific disturbances in normal social interaction. Neurophysiologically, face inversion results in an amplitude increase of the event-related potential (ERP) component N170. This face inversion effect (FIE) presumably reflects a disruption of face-specific configuration processing.

Mental health in Japanese members of the United Nations peacekeeping contingent in the Golan Heights: effects of deployment and the Middle East situation.

This study evaluates the mental health of Japan Self-Defense Force (JSDF) members of the peacekeeping contingent in the Golan Heights before and since the Second Gulf War between 1998 and 2003. Before the war, the General Health Questionnaire 30 (GHQ30) scores during and after duty tended to be lower than those before duty; all scores were lower than those of adult Japanese men in general. After the war, GHQ30 scores did not significantly change between before, during, and after duty.

Social anxiety predicts unconsciously provoked emotional responses to facial expression.

Previous psychometric studies using a visual search task suggested that interpersonal fear in individuals with social anxiety disorder (SAD) may be processed by unconscious preattentive mechanisms. However, little is known about relationships between social anxiety and preattentive emotional responses. We explored whether social anxiety is associated with preattentive emotional responses to facial expression.

Effect of paroxetine on a model of posttraumatic stress disorder in rats.

To better understand neurochemical and psychopharmacological aspects of post-traumatic stress disorder (PTSD), it is necessary to establish an animal model of PTSD in which behavioral changes persist after the initial traumatization. We administered inescapable electric foot-shock (IS) to male Wistar rats in a shuttle-box with the gate closed. With or without paroxetine (PRX; belonging to selective serotonin reuptake inhibitors) treatment for 2 weeks after IS, we performed an avoidance/escape task session in the shuttle-box using signal lights as non-specific anxiogenic stimulants.
