Influence of mass media

In media studies, mass communication, media psychology, communication theory, and sociology, media influence and the media effect are topics relating to mass media and media culture's effects on individuals' or audiences' thoughts, attitudes, and behaviors. Through written, televised, or spoken channels, mass media reach large audiences. Mass media's role in shaping modern culture is a central issue for the study of culture. Media influence is the actual force exerted by a media message, resulting in either a change or reinforcement in audience or individual beliefs. Whether a media message has an effect on any of its audience members is contingent on many factors, including audience demographics and psychological characteristics. These effects can be positive or negative, abrupt or gradual, short-term or long-lasting. Not all effects result in change; some media messages reinforce an existing belief. Researchers examine an audience after media exposure for changes in cognition, belief systems, and attitudes, as well as emotional, physiological and behavioral effects. The influences of mass media (or 'media effects') are observed in various aspects of human life, from voting behaviors to perceptions of violence, from evaluations of scientists to our understanding of others' opinions. The overall influence of mass media has changed drastically over the years, and will continue to do so as the media itself develops. In the new media environment, we have dual identities - consumers and creators. We not only obtain information through new media, but also disseminate information to wide audiences. Further, the influence of the media on the psychosocial development of children is profound. Thus, it is important for physicians to discuss with parents their child's exposure to media and to provide guidance on age-appropriate use of any media, including television, radio, music, video games and the Internet. There are several scholarly studies which addresses media and its effects.
