Temperament – a psychobiological approach to Harm Avoidance and Novelty Seeking
Ray, J. (2005). Temperamental development in the rat. Department of Psychology, Göteborg University, Sweden. This thesis explores if rats can be said to have a temperament, and if that is the case, how it changes with age and how it is related to brain neurochemistry. Using the hole board and canopy tests (considered to measure exploration and anxiety respectively), behaviour was studied in Wis...
متن کاملNovelty Seeking, Harm Avoidance, and Cerebral Responses to Conflict Anticipation: An Exploratory Study
Proactive control allows us to maneuver a changing environment and individuals are distinct in how they anticipate and approach such changes. Here, we examined how individual differences in personality traits influence cerebral responses to conflict anticipation, a critical process of proactive control. We explored this issue in an fMRI study of the stop signal task, in which the probability of...
متن کاملNovelty seeking and harm avoidance in Parkinson's disease: effects of asymmetric dopamine deficiency.
OBJECTIVES Although changes in novelty seeking and harm avoidance have been reported among patients with Parkinson's disease (PD), the findings regarding the neurochemical correlates of such changes are inconsistent. This study was designed to examine the hypothesis that different patterns of motor and neurochemical asymmetry in PD may have contributed to the conflicting results. METHODS Fort...
متن کامل[Dopamine system genes and personality traits of extraversion and novelty seeking].
Dopamine neurotransmissin is thought to play a relevant role in behavioral reinforcement system. Polymorphism of the genes involved in dopamine system has been reported for association with psychological traits related to impulsive and sensation seeking behaviors. The study was aimed at a search for association of catechol-O-metyltransferase (COMT) and dopamine receptor D4 (DRD4) gene polymorph...
متن کاملThe Biogeographic Origins of Novelty-Seeking Traits
This paper empirically investigates the biogeographic determinants of the human DRD4 exon III locus, a particular gene variant associated with the human personality trait of novelty-seeking behavior. Providing a novel compilation of worldwide DRD4 exon III allele frequencies in a large sample of indigenous populations around the world, this study employs population-specific biogeographic charac...
