Does exposure to media violence make us more violent? Do stereotypes in the media affect the way we see different social groups? Do media institutions play any role in social change? Media Effects is a concise introduction which studies the ways in which media use affects society. James Shanahan explores how researchers and society became interested in media effects, outlines the important developments in the field, and looks at how research on narrative is playing a progressively important role in revealing what we know. The book also provides a timely interweaving of different perspectives, ranging from concerned and critical voices within media studies to quantitative psychological approaches which tend to be more sceptical about powerful media effects. Concise and authoritative, Media Effects is the go-to text for students and scholars getting to grips with this fascinating and important topic.
