Third, as individuals get older and come to have more control over their lives, they tend to select environments that are comfortable for their temperament and personality. For example, individual differences in sensation seeking influence career choices (Nicholson, Soane, Fenton-O'Creevy, & Willman, 2005). By choosing environments that “fit” their personalities, individuals choose environments in which actions based on their personalities are more likely to be reinforced. Researchers have contended that these processes contribute to the stability of personality: individuals’ perspectives tend to be confirmed and reinforced (Caspi & Roberts, 2001).
