Randomized trial examines latent inhibition and conditioned inhibition in participants with varying schizotypy levels, suggesting implications for understanding schizophrenia symptoms.
Key Points
To investigate how symptoms of schizophrenia and hallucination proneness affect latent and conditioned inhibition through a perceptual learning paradigm.
260 participants completed symptom questionnaires before a perceptual learning task.
Participants were pre-exposed to similar checkerboards in separate or intermixed formats.
Reaction times and accuracy were measured in distinguishing checkerboard differences.
Participants showed quicker discrimination of similar checkerboards after pre-exposure.
Higher unusual beliefs and lower hallucination proneness were linked to poorer accuracy after blocked pre-exposure.
Greater unusual beliefs and lower cognitive disorganisation were associated with slower reaction times after mixed pre-exposure.
