Lauren Slater (born March 21, 1963) is an American psychologist and writer. She is the author of seven books, including Welcome To My Country (1996), Prozac Diary (1998), and Lying: A Metaphorical Memoir (2000). Her 2004 Opening Skinner's Box: Great Psychology Experiments of the Twentieth Century, a description of psychology experiments "narrated as stories", has drawn both praise and criticism. It was nominated for a Los Angeles Times Kirsch award for science and technology writing, and was named as a 2005 Bild Der Wissenschaft book of the year in Germany. Criticism has focused on Slater's research methods and on the extent to which some of the experiences she describes may have been fictionalized.
