Abstract
The reliability of saccades was studied in young healthy persons. Reflexive saccades, antisaccades as well as remembered saccades were evaluated. The results show a large interperson variation and a small intraperson variation of the latency times. This indicates that subjects can act as their own controls in a repeated measures design. The reliability of the error rate must be considered with caution because of the very small number of errors made by normal youth. Our findings may have implications for experimental and clinical studies.
