St. Joseph News-Press: Some people believe that the rise in the use of social networking sites, texting and the Internet has led to an increase in the number of people becoming introverted or less social, while others do not. “I certainly think the age of electronics is something that could contribute to and maintain a person’s anxiety,” said Amy Przeworski, assistant professor of psychology. “I don’t think it necessarily breeds anxiety. When we think of extrovert-ism and introvert-ism, there is a big component that’s genetic.”
