Why do some kids -- but not all kids -- develop imaginary friends? And how exactly do kids benefit from their relationships with imaginary companions? What do they acquire from these relationships? Our guest is Tracy Gleason, a developmental psychologist and professor of psychology at Wellesley College. She will speak about her interesting research on young children's imaginary companions at 7pm on Thursday the 27th in TU's Tyrrell Hall. More info on this gathering is posted here.
