Author information

  • 1Psychology Department, John Carroll University, University Heights, OH 44118.


32 undergraduates viewed 10 photographs of faces for 3 sec. each in a brightly or dimly illuminated room. Then they viewed 40 photographs in the same light, including the original 10, and identified each photograph as new or old. Subjects recognized significantly more photographs in the bright illumination condition, possibly because that condition allowed for more processing of information.
