See a replica of famed psychoanalyst Sigmund Freud’s couch, a vintage straight jacket, artifacts from the notorious Stanford Prison Experiment and more at the new National Museum of Psychology at a free grand opening event from 4 to 7 p.m. Wednesday.

The museum, on the University of Akron campus at the corner of Mill and College streets, is the only one of its kind in the country and the largest collection in the world of artifacts, photographs, film and papers dealing with the history of psychology.

“Psychology is all around us... part of everyday life” and the museum aims to allow visitors to explore that idea, said Cathy Faye, assistant director of the Cummings Center for the History of Psychology, which houses the museum.

For the grand opening, visitors can park at metered spots on the street or flat lots at the corner of College and Exchange streets.

Private donations paid for the museum.
