Abstract

Schizophrenia and depression have an overlap in symptomatology, namely a slowing in both motor and mental activities, denoted in depression as 'psychomotor retardation' and in schizophrenia as 'psychomotor poverty'. By means of a new technique that allows the measurement of psychomotor speed and the computerized analysis of writing movements recorded during the performance of the Digit Symbol Test, it indeed proved to be possible to observe a slowing in both disorders. In addition, a different structure of slowing in the two patient groups could be identified.
