Abstract: One-hundred and thirty-six univeristy students were administered the Launay-Slade Hallucination Scale (LSHS). Low and high scorers then completed a visual and an auditory task that utilized non-hypnotic suggestion and ambiguous stimuli. The high LSHS group reported a significantly greater number of meaningful visual and auditory experiences in response to the ambiguous stimulation. It is argued that these phenomena are hallucinations and demonstrate the possibility of researching hallucinations in non-psychotic populations in a laboratory setting.
