Summary: This study is an attempt to examine the role of suggestion in perceiving satanic messages in rock-and-roll recordings presented backward. Ss (N = 65) were placed in one of three groups: 1. no suggestion regarding message; 2. suggestion that words could be distinguished in the record; 3. suggestion that satanic messages could be distinguished in the record. A significantly greater proportion of Ss in the second group reported hearing more words than the members of the other groups. A significantly greater proportion of Ss in the third group reported hearing more messages with satanic content than the members of the other groups.
