Children with Rett Syndrome (RS) are supposed to present progressive regression of psychomotor development and speech abilities as well as spontaneous hand movement loss, resulting in severe difficulties for their communication. Several studies have been reporting that RS girls use the eyes with intentional purpose for communicating or expressing desires, and these findings make possible the use of eyes movements as a tool for assessing other RS aspects, such as the cognitive aspects. Ten girls aged 4y8m to 12y10m with RS were assessed for this investigation with a computer system for visual tracking regarding their ability of recognizing concepts of color (red, yellow and blue), shape (circle, square and triangle), size (big and small) and spatial position (over and under). Results from comparing the time of eyes fixation on required and not required concepts did not differ significantly. Correlation between age advancement and ability for recognizing the concept of the color "blue" could be observed. Children did not show to recognize the most part of the required concepts when assessed with eye tracking system.
