Rapid-fire TV news bulletins or getting updates via social-networking tools such as Twitter could numb our sense of morality and make us indifferent to human suffering, CNN says.
New findings show that the streams of information provided by social networking sites are too fast for the brain’s “moral compass” to process and could harm young people’s emotional development.
Before the brain can fully digest the anguish and suffering of a story, it is being bombarded by the next news bulletin or the latest Twitter update, according to a University of Southern California study.
“If things are happening too fast, you may not ever fully experience emotions about other people’s psychological states and that would have implications for your morality,” said researcher Mary Helen Immordino-Yang.
The report, published next week in Proceedings of the National Academy of Sciences Online Early Edition, studied how volunteers responded to real-life stories chosen to stimulate admiration for virtue or skill, or compassion for physical or social pain. iReport.com: Growing pains for Twitter, Facebook?
Brain scans showed humans can process and respond very quickly to signs of physical pain in others, but took longer to show admiration of compassion.
“For some kinds of thought, especially moral decision-making about other people’s social and psychological situations, we need to allow for adequate time and refection,” said Immordio-Yang.
She said the study raises questions about the emotional cost, particularly for young people, of heavy reliance on a torrent of news snippets delivered via TV and online feeds such as Twitter.
