Dear Editor,rnWhen two stimuli such as a tone and a visual stimulus are repeatedly presented together, individuals diagnosed with hallucinations tend to report hearing the tone subsequently in response to the visual stimulus alone [1].Such conditioned hallucinations involved evoked sensory representations as evidenced by increased neural activation in tone-responsive brain regions during the conditioned hallucinations.These and other observations underscore the importance of prior associative experiences in driving hallucinatory perception, and reflect new efforts to conceptualize and understand psychosis from a cognitive perspective.
