Language abnormalities called Formal Thought Disorder may be present in patients with
schizophrenia. Disorganized speech is one of these abnormalities, and it may be studied by
examining the semantic relationships between parts of the text. Two such approaches are
lexical cohesion and LSA coherence. Previous studies have found apparently contradictory
evidence, with lexical cohesion being increased in the discourse of patients with Formal
Thought Disorder and LSA coherence being decreased. In this study, we tested the idea that
these findings are not contradictory, and that one may find both these disturbances in the
same sample of patients, with both explaining relevant clinical variables independently of
each other. Results didn’t provide strong support for our hypotheses. We attempt to provide
explanations for this failure to find the expected results. Methodological differences with
previous literature, low subject number and lack of control of certain symptomatology
variables may explain our null findings.
