The Effects of “Media Tech Neck”: The Impact of Spinal Flexion on Cognitive and Emotional Processing of Videos
Adoption of mobile devices (e.g., smart phones and tablets) has popularized a neck-down posture during media consumption that is different from the traditional upright body posture for video viewing. A neck-down posture exerts substantial pressure upon the spine, and this posture has been previously linked to psychological effects. This study advances the literature by studying the impact of posture effects on processing audiovisual information. In a mixed design experiment (N = 87), the effect of neck posture when viewing 24 video PSAs was tested using physiological and self-report measures. Multilevel modeling analyses of heart rate and corrugator data showed that spinal flexion lowered attentional engagement and caused incongruent emotional responses to the messages compared to a neutral spine posture. However, spinal-flexion participants exhibited greater skin conductance, counter to the predicted emotional disengagement. The impact of neck posture on message processing was largest at the beginning of the experiment and faded over time.
期刊介绍：
Empirical research in communication began in the 20th century, and there are more researchers pursuing answers to communication questions today than at any other time. The editorial goal of Communication Research is to offer a special opportunity for reflection and change in the new millennium. To qualify for publication, research should, first, be explicitly tied to some form of communication; second, be theoretically driven with results that inform theory; third, use the most rigorous empirical methods; and fourth, be directly linked to the most important problems and issues facing humankind. Critieria do not privilege any particular context; indeed, we believe that the key problems facing humankind occur in close relationships, groups, organiations, and cultures.
