Abstract
A computer system has been developed for the evaluation and rehabilitation of neuropsychological disorders, especially, language disorders. This system is based on a computer driven videodisc. The videodisc can contain up to 54 000 pictures per side (36 min played at 25 pictures per second) and offers an interactive control and fast retrieval of pictures and sounds. To illustrate the use of the system, we give the example of an oral confrontation naming task. A computer program monitors the presentation of pictures to the patient and measures naming response times. The program allows a quantitative evaluation of the patient's disorders, gives a profile with printed results, and helps to monitor progress. It can also supply different cues to help the patient in oral production of words such as oral and/or written (superimposed on the picture displayed) first sound letter of the word or oral prerecorded contextual sentences to complete. The videodisc-computer association allows excellent testing reproductibility. It is efficient, simple to use for the therapist, makes self-training possible for the patient and is amenable to development.
