These were trimmed to the score 3 S.

After observing the faces of people for a long time, I see them differently. In addition, hallucination predisposition was associated with increased clinical symptoms. Finally, hallucinatory experiences were described as more pleasant than unpleasant: These analyses suggest that the factors identified with the PCA were fairly robust and that three separate factors may be identified.

Despite variability in the prevalence and frequency ratings of hallucinatory experiences in the current sample, intrusive or vivid thoughts and hypnagogic and hypnopompic hallucinations i. Despite the wide empirical evidence that a substantial proportion of the healthy general population has psychosis-like experiences, virtually no studies have addressed whether the experiences reported by non-clinical samples are indeed similar to the experiences of clinical samples.

An important argument for the validity of this solution is that repeated factor analyses with dif- ferent rotations yielded practically identical solutions. Hence, differences between males and females in hallucinatory experiences were examined using independent samples t -tests, whereas Pearson correlation coefficients were used to probe the relationship between the affective content of the hallucinatory experiences and the perceived degree of control over the experiences means for the items tapping into the perceived control over the beginning vs.


Parametric statistical tests were used as the normality assumption was verified. The omnipotence of voices. Individuals with higher hallucination predisposition presented more anxious-depressive and schizotypal symptomatology.
