Fractal property of eye movements in schizophrenia.
On the basis of a temporal model of animal behavior we conducted temporal analysis of eye movements in schizophrenic subjects (n = 10) and normal controls (n = 10). We found a fractal property in schizophrenic subjects, the fixation time of eye movement during reading ambiguous and difficult sentences showing a clear inverse power law distribution. An exponential distribution of a nonfractal nature was found in normal controls.
