✦ Synopsis

In 40 normal subjects and in 21 patients with anomic, Wernicke's, and Broca's aphasia, eye movements were registered with DC-EOG during reading of two standardized texts and analysed with respect to the number of fixations and regressions and reading time. Patients with these aphasic syndromes developed different internal strategies of their saccadic construction: Patients with Wernicke's aphasia showed increasing difficulty in overcoming the text with a tendency to make smaller leaps over the line, with almost a complete disintegration of the saccadic structure ("strategy of small and smallest steps"). The saccadic pattern in Broca's aphasics was clearly better preserved. During oral reading there was a characteristic increase in fixation times and number of regressions ("motor waiting and searching behaviour"). Patients with anomic aphasia showed alterations most similar to the reading behaviour of unskilled normal readers.
