title: Individual differences in vigor and deliberation: development of two new measures from an evolutionary psychology theory of human motivation.
abstract: Three studies (total N=403 participants; M age = 31.1 yr.; SD = 13.8) are reported on the development, psychometric properties, and convergent and discriminant validities of two individual differences dimensions of Vigor (constructive arousal and energy that drives the general intensity of behavior) and Deliberation (prudence in the delay of immediate action and consideration of competing motives, emotions, and consequences of action that promote convergence of behavior toward socially desirable outcomes). These dimensions are part of Bernard, Mills, Swenson, and Walsh's evolutionary psychology theory of human motivation. Analysis suggests Vigor and Deliberation scales have reasonably good psychometric properties and may aid research on motivation from an evolutionary perspective.
