N2 - An experiment is described which investigated cognitive inhibition in schizophrenia. It is noted that both the abnormal and cognitive literatures use the concept of inhibition. Frith (1979) suggests that the more cognitive symptoms of schizophrenia may be due to the failure to limit the current contents of consciousness due to a failure adequately to inhibit the output of preconscious processes.Current thinking in cognitive psychology suggests that in the process of selective attention there is active inhibition of distractor information.
