Randomized Controlled Trial Clinical Trial
The effects of varying information content and speaking aloud on auditory hallucinations.
The aim of this study was to investigate why requiring hallucinating schizophrenic subjects to read aloud produces large reductions in reports of auditory hallucinations. In Expt 1 hallucinating subjects (N = 9) were required to sort cards quietly into one, two, four, 13 and 26 piles. ⋯ Sorting cards into two piles whilst saying the colour of the card produced the largest reductions in the reports of hallucinations. It was concluded that it was the requirement to make overt motor and verbal response that produced the large reductions in reports of auditory hallucinations in the reading-aloud task.
