obsolete novelty seeking personality trait (obsolete MONDO:0044269)
OBSOLETE. Human personality traits that can be reliably measured by rating scales show a considerable heritable component. One such instrument is the tridimensional personality questionnaire (TPQ), which was designed by {6:Cloninger et al. (1993)} to measure 4 distinct domains of temperament--novelty seeking, harm avoidance, reward dependence, and persistence--that are hypothesized to be based on distinct neurochemical and genetic substrates.nnRisk-taking is a characteristic of behaviors that occur under conditions of uncertainty and involves a tradeoff between beneficial versus detrimental outcomes, perceived or real. Risk-taking may or may not involve conscious evaluation of the probability and magnitude of possible outcomes ({1:Anokhin et al., 2009}).nnSee also harm avoidance (OMIM:607834) and pathologic gambling (OMIM:606349), which may be related.
