OBJECTIVE Norepinephrine is an important chemical messenger that is involved in mood and stress in humans, and is reabsorbed by the norepinephrine transporter (NET). According to Cloninger's theory, the noradrenergic system mediates the personality trait of reward dependence. Thus far, although association studies on NET gene polymorphisms and Cloninger's personality traits have been reported, ...

BACKGROUND The Levels of Emotional Awareness Scale (LEAS) was developed to assess five levels of emotional awareness: bodily sensations, action tendencies, single emotions, blends of emotion, and combinations of blends. It is a paper and pencil performance questionnaire that presents 20 emotion-evoking scenes. We developed a Japanese version of the LEAS (LEAS-J), and its reliability and validit...

Throughout the development of psychology the delineation of personality has played a central role. Together with the NEO-PI-R, a questionnaire derived from the Five Factor Model of Personality, and recent advances in research technology it is now possible to investigate the relationship between personality features and neurophysiological brain processes. The NEO-FFI, the short version of the NE...

BACKGROUND Research demonstrates that most of the menopausal symptoms and problems are the reflection of individual and social circumstances rather than the endocrine events of the menopause. As majority of women live 30 years or more through postmenopausal period, treatment and following up their problems during this period is among the main duties of a midwife. The aim of this study is to det...

Personality neuroscience is a rapidly expanding field of study fueled by a growing interest in understanding the structural brain correlates of individual differences in personality. Data on the structural brain correlates of personality are especially lacking from large-scale studies, and are nearly nonexistent in the adolescent age group. Furthermore, the role of sex differences in structural...

OBJECTIVE To examine the association between Five Factor Model personality traits (Neuroticism, Extraversion, Openness to experience, Agreeableness, Conscientiousness) and physician-quantified aggregate morbidity in a sample of older adults in primary care. METHODS A total of 449 primary care patients, ranging in age from 65 to 97 years (75 +/- 6.9 (mean +/- standard deviation)), completed th...

BACKGROUND Psychological abnormalities, including anxiety, have been observed in patients with musician's dystonia (MD). It is unclear if these conditions develop prior to MD or if they are psychoreactive phenomena. METHODS Psychological conditions were studied in 44 professional musicians with MD, 45 healthy musicians, and 44 healthy nonmusicians using the State-Trait Anxiety Inventory (STAI...

In two German samples we investigated whether three major personality prototypes (resilient, overcontrolled, and undercontrolled) can be replicated across different Big Five instruments (NEO-FFI and NEO-PI-R), and whether they can be differentiated into replicable subtypes. For prototypes and subtypes, replicability within and consistency across samples was quantitatively measured. Three replic...
