One variant of the dopamine receptor gene, called 7R, is particularly associated with impulsive, novelty-seeking behavior
; perhaps early humans with this gene were more likely to migrate to new areas.

predicts vulnerability in a rodent model of depression," Physiology and Behavior, vol.
Specifically, it uses cluster analysis to identify and profile particular segment groups of travelers to major Mediterranean sun-and-sand destinations based on their novelty-seeking behavior
. The aim is to examine whether travelers' novelty-seeking behavior
affects their likelihood to return to the destination.
ADHD is characterized primarily by impulsivity, risk taking, and novelty-seeking behavior
. "In contrast, the behavioral manifestations of OCD seem to lie on the opposite end of an impulsive-compulsive spectrum," typified by inhibited temperament, avoidance of novel stimuli, increased risk avoidance, and lower than normal impulsivity.
"People are trying to understand what is the basis of novelty-seeking behavior
in humans and in animals," who Robinson, who also is affiliated with the Neuroscience Program at Illinois.
Previous research suggests that a person may engage in exploration of the environment (e.g., variety-seeking or novelty-seeking behavior
) to achieve a satisfactory cognitive level, or when feeling that the amount of stimulation is below an optimal stimulation level (Menon & Kahn, 1995; Steenkamp & Baumgartner).
The dopaminergic system is particularly important for the expression of novelty-seeking behavior
(Bardo et al.
For instance, a preteen's tendency to seek out new experiences (i.e., high novelty-seeking behavior
) was found to be predictive of alcohol abuse at age 27 (Cloninger et al.
A version of the D4 dopamine receptor gene, or D4DR, cited as a key factor in producing novelty-seeking behavior
(SN: 1/6/96, p.
One human gene that personality researchers have focused on is called DRD4, which encodes a dopamine receptor and is thought to play a role in exploration and novelty-seeking behavior
The longer gene may endow a person with receptors that respond to dopamine by promoting novelty-seeking behavior
, Ebstein and his colleagues theorize.
HONOLULU -- People who engage in novelty-seeking behavior
or activities that involve the integration of ideas appear to have a decreased risk of developing Alzheimer's disease, Thomas Fritsch, Ph.D., reported at the annual meeting of the American Academy of Neurology.
