Self-regulation and performance in high-fidelity simulations: An extension of ego-depletion research

Abstract

This article extends the research literature related to "ego-depletion." Although numerous studies have focused on the self-regulatory failure associated with ego-depletion, the extant literature is generally characterized by relatively simple behavioral manipulations and dependent measures. Two studies are described that extend previous ego-depletion findings by employing a high-fidelity, customer service simulation as an ego-depleting manipulation (Study 1) and by using performance on a cognitively demanding naval combat simulator as a dependent measure (Study 2). Results of both studies show the generalizability of the effects of ego-depletion; the implications for self-regulatory failure in more naturalistic settings are discussed.
