7. Gain/loss framing moderates the VMPFC’s response to persuasive messages when behaviors have personal outcomes

Author

Kriss, Lauren and Minich, Matt

Abstract

Activity within the ventral medial prefrontal cortex (VMPFC) during encoding of persuasive messages has been shown to predict message-consistent behaviors both within scanner samples and at the population level. This suggests that neuroimaging can aid in the development of better persuasive messages, but little is known about how the brain responds to different message features. Building on past findings, the current study found that gain-framed persuasive messages elicited more VMPFC activation than loss-framed messages, but only when messages addressed outcomes that would be experienced by participants directly. Participants also perceived gain-framed messages as more effective than loss-framed messages, and self-reported perceptions of message effectiveness were positively correlated with VMPFC activation. These results support theories that VMPFC activity during message encoding indexes perceptions of value and self-relevance and demonstrate that established theories of persuasion can improve the understanding of the neural correlates of persuasion.

Abstract

Rates of adolescent mood disorders and adolescent smartphone use have risen in parallel, leading some to suggest that smartphone use might have detrimental effects on adolescents' moods. Alternatively, it is possible that adolescents turn to smartphone use when experiencing negative mood. Past experimental study suggests that certain smartphone activities can reduce adolescents' negative moods or induce more positive moods, but little is known about the effects of real-world smartphone use, which can involve many different activities. A sample of N = 253 adolescents participated in an Ecological Momentary Assessment (EMA) procedure, which assessed which smartphone activities they were engaged in at random moments throughout the day. This procedure also prompted adolescents to rate their moods before and during smartphone use. Adolescents reported mood improvements during almost all smartphone activities and did not report that moods became more negative during any smartphone activity. Mood improvements were the largest when adolescents said they were listening to music, podcasts, or audiobooks. This may suggest some adolescent smartphone use is driven by a desire to alleviate negative mood. [ABSTRACT FROM AUTHOR]
