Abstract

Media, as one of the most significant mechanisms influencing the human mind, behavior, and emotions, has become a central subject of extensive interdisciplinary research in recent decades. This study, employing a meta-analytic and exploratory approach, examines the role of three key neural mediators—serotonin, dopamine, and norepinephrine—in the development of emotion, motivation, addiction, and media dependency. The theoretical framework of the article is grounded in the bidirectional interaction between the central nervous system and media experiences, striving to establish a connection between findings in neuroscience and classical communication theories.

A comparative analysis of three decades of research in neuroscience, psychology, communication, and media studies reveals that media, through mechanisms such as instant rewards, dopaminergic stimulation, alterations in serotonin levels, and activation of the sympathetic nervous system, create a quasi-reality of pleasure and excitement. This state fosters the continuation of media consumption and, in some cases, leads to cognitive and behavioral dependency.

The meta-analytic approach utilizes three empirical studies conducted by the author and collaborators:

A qualitative-experimental study on television removal within families, investigating changes in lifestyle, order, calmness, and aggression in the absence of media. Data were collected from ten families through in-depth interviews and daily journaling, and analyzed using thematic analysis.

A semi-experimental study involving media stimulation through the presentation of violent and non-violent films to 60 students aged 18-25, measuring physiological indicators (heart rate, muscle tension, skin perspiration, respiration, and skin temperature) and aggressive emotions via a standard 35-item questionnaire and statistical tests (t-test, Kolmogorov-Smirnov).

A content analysis of the most popular Instagram pages, analyzing 150 top pages based on followers, likes, and comments. Using Mayring's eight-stage method and NVivo software, 512 codes were identified to explore the behavioral consequences, couple relationships, and lifestyle of users.

The synthesis of these findings presents a multifaceted view of the impact of media on the brain and human behavior. Media influence audiences through three primary pathways: changes in lifestyle and leisure activities, transformations in social and familial relationships, and physiological and emotional stimulation. Moreover, moderating factors such as real-world interaction, physical activity, and enhanced media literacy can help mitigate potential negative effects. This study offers an innovative interdisciplinary approach, integrating behavioral, social, and neuro-physiological perspectives, opening new avenues for future research in cognitive neuroscience and media literacy.
