UNASSIGNED: @entity161 is a @entity74 characterized by numerous diverse signs and symptoms. Individuals with prominent, persistent, and @entity191 are thought to encompass a distinct subtype of @entity161 . Previous work, including studies involving neuropsychological evaluations, has supported this position. The present study sought to further examine whether @entity51 @entity1 are cognitively distinct from @entity51 @entity1 with @entity161 . @entity149 including tests of verbal memory, vigilance, processing speed, reasoning, and working memory was administered to 657 @entity1 with @entity161 . Of these, 144 (22  %) @entity1 were classified as @entity51 @entity1 using a proxy identification method based on severity, persistence over time, and possible secondary sources (e.g., @entity308 ) of negative symptoms. @entity51 @entity1 with @entity161 performed worse on all tests of cognition relative to @entity51 @entity1 . These @entity1 were characterized by a generalized @entity73 on the order of about 0.4 standard deviations below that of @entity51 @entity1 . However, when comparing @entity51 @entity1 to @entity51 @entity1 who also present with negative symptoms, albeit not enduring or primary, no group differences in cognitive performance were found. Furthermore, a discriminant function analysis classifying @entity1 into @entity51 / @entity51 groups based on cognitive scores demonstrated only 62.3  % accuracy, meaning over one-third of individuals were misclassified. The @entity51 subtype of @entity161 is not markedly distinct from @entity51 @entity161 in terms of neurocognitive performance. While @entity51 @entity1 tend to have poorer performance on cognitive tests, the magnitude of this effect is relatively modest, translating to over 70  % overlap in scores between groups.
