DNA polymorphism in the FKBP5 gene affects impulsivity in intertemporal choice.

Introduction: Impulsivity in intertemporal choice has been operationalized as "delay discounting", referring to the preference for a sooner, smaller reward. FK506 binding protein 5 (FKBP5) is a co-chaperone of the glucocorticoid receptor (GR). FKBP5 overexpression causes GR resistance, resulting in increased plasma cortisol levels.

Six-year stability of affective temperaments as measured by TEMPS-A.

Background: A number of psychopathological and neurobiological studies on affective temperament have been conducted based on the assumption that temperament is a stable trait. However, few studies have actually assessed the long-term stability of affective temperament. The objective of this study is to evaluate the 6-year stability of affective temperaments as measured by the Temperament Evaluation of Memphis, Pisa, Paris and San Diego--Autoquestionnaire version (TEMPS-A) in a non-clinical adult population.
