Agentic extraversion as a predictor of effort-related cardiovascular response
چکیده انگلیسی

The present study examined an extraversion-based extension of the integrative model of cardiovascular effort regulation by Wright and Kirby [Wright, R.A., Kirby, L.D., 2001. Effort determination of cardiovascular response: an integrative analysis with applications in social psychology. In: Zanna, M.P. (Ed.), Advances in Experimental Social Psychology, Academic Press, San Diego, CA, pp. 255–307.]. This model explains cardiovascular effort reactivity in terms of task difficulty, ability appraisal, and success importance. Aggregate measures of cardiovascular variables (alpha-adrenergic, beta-adrenergic, and cholinergic activation components) were used to measure extraversion-based differences in effort. Subjects performed a sequential letter task (n-back verbal working memory task) with four levels of difficulty. Agentic extraverts (n = 10) appraised their ability and happiness as significantly higher than introverts (n = 10). Introverts showed the expected shark-fin shaped pattern of effort-related cardiovascular reactivity for the alpha-adrenergic and cholinergic activation components. Effort decreased after the moderately difficult 2-back task. Results provide first evidence for an extraversion-based extension of the model and are discussed with regard to mood and resource allocation as possible mechanisms.
