Predicting persuasion-induced behavior change from the brain.

ABSTRACT: Although persuasive messages often alter people's self-reported attitudes and intentions to perform behaviors, these self-reports do not necessarily predict behavior change. We demonstrate that neural responses to persuasive messages can predict variability in behavior change in the subsequent week. Specifically, an a priori region of interest (ROI) in medial prefrontal cortex (MPFC) was reliably associated with behavior change (r = 0.49, p < 0.05). Additionally, an iterative cross-validation approach using activity in this MPFC ROI predicted an average 23% of the variance in behavior change beyond the variance predicted by self-reported attitudes and intentions. Thus, neural signals can predict behavioral changes that are not predicted from self-reported attitudes and intentions alone. Additionally, this is the first functional magnetic resonance imaging study to demonstrate that a neural signal can predict complex real world behavior days in advance.

Project description:RationaleBehaviors such as hand-washing and vaccination save human lives during the COVID-19 pandemic and beyond. Yet, people differ widely in their willingness to engage in them. This investigation examines whether people's willingness to protect themselves physically from contracting coronavirus depends on their self-esteem. Based on self-verification theory, we propose that people who hold negative self-views are less motivated to protect their health which reduces their willingness to engage in recommended preventive measures such as mask-wearing and social-distancing.ObjectiveWe set out to test (i) whether self-esteem predicts people's willingness to engage in COVID-19 prevention behaviors, (ii) whether this relationship is due to variance in motivation to protect one's health (as well as alternative mechanisms), and (iii) whether health messages can more successfully persuade low self-esteem people to follow preventive measures by framing those behaviors around protecting the health of others (vs. oneself).MethodsFour studies were conducted with U.S. and German residents. In Study 1, we examine the association between self-esteem, willingness to engage in self-protection behavior, health motivation, and several alternative accounts. In Study 2, we manipulate state self-esteem, and in Studies 3 and 4, we vary the target of COVID-19 prevention behaviors (self vs. other).ResultsPeople with chronic or temporarily induced low self-esteem report a lower willingness to engage in COVID-19 prevention behaviors because they lack motivation to protect their health. Varying the protection target of preventive behaviors (self vs. others) interacts with self-esteem: Low self-esteem people are more willing to follow preventive measures (e.g., vaccination) when they are framed as protecting others (vs. oneself).ConclusionsSelf-esteem impacts people's behavior during a global pandemic and needs to be considered when designing health communications. Public health messages can increase compliance among individuals with lower self-esteem by framing prevention behaviors as a way to protect the health of others.
