Resistance to persuasion as self-regulation: Ego-depletion and its effects on attitude change processes

Counterarguing persuasive messages requires active control processes (e.g., generation and application of contradictory information) similar to those involved in other forms of self-regulation. Prior research has indicated that self-regulation ability is a finite resource subject to temporary depletion with use, and so engaging in self-regulatory tasks could impair individuals’ ability to subsequently counterargue. Participants completed an initial task designed to deplete or not deplete their regulatory resources. Following the manipulation, participants read a message supporting a counterattitudinal policy. Results indicated that prior self-regulation reduced subsequent resistance, primarily when the message arguments were specious. Counterargument appears to be a self-regulatory process that can be undermined when self-regulatory resources have previously been diminished.
