In an experiment, 44 undergraduate students were asked to listen to white noise and instructed to press a button when they believed that they were hearing a recording of Bing Crosby’s White Christmas without this recording actually being presented.
Fourteen participants (32%) pressed the button at least once. These participants had higher scores on fantasy proneness and the Launay–Slade Hallucination Scale (LSHS) compared to participants without hallucinatory reports. Both groups did not differ in terms of imagery vividness or sensitivity to social demands.
Logistic regression suggested that fantasy proneness is a better predictor of hallucinatory reports than are LSHS scores. This might imply that hallucinatory reports obtained during the White Christmas test reflect a non-specific preference for odd items rather than schizophrenia-like internal experiences.
This according to “Another White Christmas: Fantasy proneness and reports of hallucinatory experiences in undergraduate students” by Harald Merckelbach and Vincent van de Ven (Journal of behavior therapy and experimental psychiatry XXXII/3 [September 2001] pp. 137–44).
