Join us below at noon Eastern on Thursday (July 26) for a live 30-minute online chat with psychology graduate student Maria Konnikova of Columbia University in New York, who will discuss the social and literary roots of anxiety. Her "Literally Psyched" blog with the Scientific American network investigates tests of psychology as conceived in literature. Her July 23 post "Warning: This Story Might Make You Anxious," was one of the most popular  on this week. In the post, she discusses Daniel Smith's new book, Monkey Mind, and what it reveals about the causes of anxiety. 

Anxiety disorders are the most prevalent psychiatric disease category. Clinical anxiety also increases one's risk for major depression and substance abuse. 

Konnikova currently is working on her book, Mastermind: How to Think Like Sherlock Holmes (Viking Adult, 2013).

We invite you to post chat questions in advance in the comments below. We have already turned on the capacity to log-in to the chat box below if visitors would like to chat amongst themselves until Konnikova joins in at noon on Thursday, July 26.
