REALITY MONITORING IN A HYPOTHETICALLY HA LLUCINATION-PRONE POPULATION

The aim of this work was to analyze the performance of hypothetically hallucination-prone subjects in source discrimination tasks. Two exper iments were carried out with external source (pictorial and verbal) di scrimination tasks. In Experiment 1, material and encoding task (namin g, function, and mental imagery) were manipulated. In Experiment 2, th e variables were material, encoding task and delay of memory test. Res ults showed that hypothetically hallucination-prone subjects encode ex ternal information and make use of information about prototypical feat ures of memory traces in a similar way to non-prone subjects. These fi ndings, discussed within Johnson and Raye's reality monitoring model, may serve to define the conditions under which normal and abnormal sou rce discrimination failures occur.
