[Study of disorders of speech and thinking in schizophrenia by recording eye movements during reading].

Eye movements (EM) were recorded during reading in 16 patients with continuous schizophrenia of long (9 to 35 years) standing. EM in patients were found to differ materially from those in normals. Two pathological forms (strategies) of successive text review were revealed. As far as the first strategy is concerned, it is characterized by the predominance of disorganization of perceptive motor reading automatism. As to the second one, the reading automatism is on the whole retained but demonstrates the signs of stereotypy, loss of motivation to realization of the operations of control and adequate adaptive rearrangement. It is concluded that speech and thinking disorders formed as a result of long schizophrenia are pathogenetically non-uniform and reflect nonspecific regularities of psychotic responsiveness.
