Exploratory behavior, or Novelty Seeking, is one of 4 temperaments according to the Cloninger’s model of personality. The other three are Harm Avoidance, Reward Dependence, and Persistence. Exploratory behavior reflects the tendency to respond strongly to novelty and cues for reward. Explorers have the tendency to crave stimulation and thrills; they tend to be attracted by large crowds and bright colors. Interestingly, exploratory behavior is influenced by specific neurotransmitter pathways in the brain and it has a heritable genetic component.
