Tridimensional Personality Questionnaire (TPQ) is a personality test.
It was devised by C. Robert Cloninger.
A newer version of the questionnaire is called Temperament and Character Inventory.
Neurobiology
Cloninger suggested that the three dimensions, novelty seeking, harm avoidance, and reward dependence, were correlated with low basal dopaminergic activity, high serotonergic activity, and low basal noradrenergic activity, respectively. Much research has gone into examining these links, e.g., with personality genetics. == References ==
