Abstract

In this study, we combined approaches from media psychology and neuroscience to ask whether brain activity in response to online antismoking messages can predict smoking behavior change. In particular, we examined activity in subregions of the medial prefrontal cortex linked to self- and value-related processing, to test whether these neurocognitive processes play a role in message-consistent behavior change. We observed significant relationships between activity in both brain regions of interest and behavior change (such that higher activity predicted a larger reduction in smoking). Furthermore, activity in these brain regions predicted variance independent of traditional, theory-driven self-report metrics such as intention, self-efficacy, and risk perceptions. We propose that valuation is an additional cognitive process that should be investigated further as we search for a mechanistic explanation of the relationship between brain activity and media effects relevant to health behavior change.

自我和价值相关区域的大脑活动对网上反吸烟信息的反应可预测行为改变。

在这项研究中，我们结合了媒体心理学和神经科学的研究方法，探究大脑对在线反吸烟信息的反应是否能预测吸烟行为的改变。特别是，我们检测了与自我和价值相关处理有关的内侧前额叶皮层亚区的活动，以检验这些神经认知过程是否在与信息一致的行为改变中发挥作用。我们观察到，这两个相关脑区的活动与行为改变之间存在明显的关系（例如，活动越多，吸烟量减少的幅度就越大）。此外，这些脑区的活动对行为变化的预测独立于传统的、理论驱动的自我报告指标，如意向、自我效能感和风险认知。我们建议，在寻找大脑活动与健康行为改变相关的媒体效应之间关系的机理解释时，应进一步研究估价这一额外的认知过程。

期刊介绍： Journal of Media Psychology (JMP) is committed to publishing original, high-quality papers which cover the broad range of media psychological research. This peer-reviewed journal focuses on how human beings select, use, and experience various media as well as how media (use) can affect their cognitions, emotions, and behaviors. Submissions must substantially advance the current state-of the art on a theoretical and/or an empirical level. To name just a few typical fields and domains of inquiry, the Journal of Media Psychology considers manuscripts dealing with research on entertainment, computer-mediated communication (including social media), human-computer interaction, e-learning, computer and video games, virtual environments, or advertising. The journal is also open to research from neighboring disciplines as far as this work ties in with psychological concepts of the uses and effects of the media. Submissions of comparative work, e.g., crossmedia, cross-gender, or cross-cultural, are encouraged. Moreover, submissions including alternative analysis procedures such as the Bayesian approach are welcome. Starting in 2015, the pre-registration of research plans will also be possible. To ensure short turn-around cycles for manuscript review and fast publication, the Journal of Media Psychology relies heavily upon electronic communication and information exchange, starting from electronic submission and continuing throughout the entire review and production process.
