title: Neurotransmitters, temperament and social functioning.
abstract: Dimensional models can be usefully employed to describe both normal and disordered personality. Studies in molecular genetics, receptor binding, peripheral monoamines and pharmacological challenges have investigated the neurochemical basis of personality. Substantial evidence now exists to support a psychobiological model but the specificity of Cloninger's theory has not always been confirmed. Clinical studies have shown both temperament and character dimensions to improve with pharmacological treatment especially in treatment responders. Some personality changes are found to be independent of clinical effects and even to occur in normal subjects. Models of personality can help in predicting treatment outcome but individual dimensions may not be useful. It is hypothesised that social adaptation is related to the character dimensions and different sources of evidence link these to serotonergic actions. However, recent clinical studies have shown a specific effect of noradrenaline on self-perception and social motivation. Drugs with specific actions on different neurotransmitters may exert a distinctive pattern of effects on personality and social behaviour.
