Abstract

Both cognitive fatigue and group membership impact how individuals respond to persuasive messaging. Cognitively demanding tasks cause mental fatigue, lessening the ability to effortfully consider persuasive messaging and increasing the likelihood of making automatic decisions based on heuristics (Schmeichel et al., 2003). Additionally, self-perception of prototypicality (i.e., level of group membership) impacts motivation to identify with and engage in group normative behavior (Hohman et al., 2017). This research project aimed to further the understanding of how prototypicality and cognitive fatigue interact and come to impact attitude and the effortful elaboration of persuasive messaging.
