In addition to potential heredity, novelty-seeking behaviors are seen with the modulation of dopamine. The overall effect of dopamine when exposed to a novel stimulus is a mass release of the neurotransmitter in reward systems of the brain including the mesolimbic pathway. [10]
Results are consistent with novelty-seeking behavior being a complex trait associated with many genes, and the variance attributable to DRD4 by itself being very small. The meta-analysis of 11 studies did find that another polymorphism in the gene, the -521C/T , showed an association with novelty seeking. [ 21 ]
Impulsive sensation-seeking: measures low socialisation, and high psychoticism, impulsivity, and sensation-seeking. The impulsivity items assess lack of planfulness and a tendency to act without thinking. The sensation seeking items describe a liking for thrills and excitement, novelty and variety, and unpredictable situations and friends. [3]
According to some publications, SNPs in DRD4 are associated with extraversion and novelty seeking. [6] Also variations in 5HTT are associated with neuroticism and harm avoidance. [7] Family and twins studies: The studies of genomics of personality traits involves families and specifically twins, because they have a high heritability of the traits.
Sensation-seeking has a strong correlation with the novelty seeking scale of Cloninger's Temperament and Character Inventory. [1] Furthermore, he presents evidence [11] [12] that this characteristic is influenced by genes. So, sensation-seeking parents are likely to have sensation-seeking children. [citation needed]
In her experience, one of the most common reasons men cheat is “the desire for sexual variety or novelty”, a need for something new or different, even if they’re in a committed relationship.
Sag is the free-spirited fire sign that loves adventure, novelty, and independence. Taurus, on the other hand, is the grounded bull that craves stability, routine, and comfort.
Novelty seeking is related to Impulsive sensation seeking in Zuckerman's alternative five model and to psychoticism in Eysenck's model. Zuckerman and Cloninger have contended that Harm Avoidance is a composite dimension comprising neurotic introversion at one end and stable extraversion at the other end.
