Abstract: Internal patterns in the PRL autoganzfeld database may shed some light on the plausibility of that hypothesis. This hypothesis would predict stronger effects for sessions where the subject is not sure about his ratings, because in those sessions the experimenter may be able to influence him or her into another direction. A secondary analysis where the scoring in sessions with an extreme rating is compared with the scoring in sessions with a lower rating shows the opposite trend. Therefore it can be concluded that this pattern does not support the auditory sound leakage hypothesis.
