Summary
Summary
It is clear that the concept of latent inhibition (LI) and the notion that it might be abnormal in schizophrenia (SZ) patients have been powerful heuristic tools for cross-species studies. Less clear has been the evidence that LI is actually abnormal in SZ, and if so, what the nature of such an abnormality might be, and which types of SZ patients might manifest it. We previously reported in two studies our ability to detect normal LI in a total of 88 SZ patients who successfully learned the non-preexposure task. Normal LI in these subjects could not be easily explained by peculiarities of the design of the LI task, or the characteristics of the study sample. Since submission of the last of these reports in 2004, we identified a total of three Medline papers in which LI was tested in SZ patients: one reported reduced LI only in unmedicated patients with predominant positive symptoms, another found elevated LI in only 6 out of 30 predominantly medicated patients who had the combination of low positive symptoms and high negative symptoms, and the third reported that LI was both reduced and elevated at different times within a single test, among medicated patients, unrelated to positive or negative symptoms. The belief that LI is abnormal in SZ persists, despite a paucity of clear, replicated, direct supportive evidence, and despite the presence of substantial relevant information that might lead us to conclude otherwise.
