Method and apparatus for the analysis of thought states in a subject. The voice of the subject is recorded during his speech into a memory. The recorded voice is digitized and the gain of the electrical signals representing the subject's voice is controlled. The digitized voice is transformed into a digital data representation and the interword time intervals (ITIs) are measured from the digital data. Parameters representative of the subject's ITI behavior are extracted from the measured ITI data and the subject is then characterized by processing and analyzing his ITI data using the extracted parameters. The characterization of the subject is carried out by calculating the correlation dimension based on his ITI data.
