Increasingly, scientists in various fields are using multimedia, such as publicly-available videos, blogs, and tweets for research purposes. A neurobiologist who noticed that people posted videos of dancing animals conducted groundbreaking research on the relationship between vocal mimicking, language acquisition, and the ability to move to rhythm. Sociologists study the posted videos, blogs, and e-mails of convicted sex offenders to identify patterns of sociopathy. Years of home videos posted to the web revealed that subjects who developed schizophrenia in their late teens displayed certain key behaviors, such as lack of eye contact, weak responsiveness, and uneven motor development in infancy and childhood.
