The follo~ing work is an experi~ontal inv8stiQation of adult/child interaction in some psychiatric disorders of childhood. The study centres upon the analysis of the effects of verbal stimuli of a therapist upon a child's body movements, and vice versa, in a situation conceived as one of 'the interaction of time series with weak feedback'. A non time series pilot project wos carried out with a young catatonic patient exhibiting marked and persistent stereotyped rocking movements of the body when seated. The time series study was carried-out with three groups of chilrlren diagnosed "Down's syndrome", childhood "psychosis", and "unclassified encephalopathy". In the pilot project the movement patterns of the patient was monitored by the use of strain gauges in a chair. In the main study however Cl sandal was adapted for a radio telemetry device placed in the heel. A series of signals correlatin~ with body movoment was picked-up using a v.h.f. receivor. Auditory series of the therapist speech responses were obtained using Cl Speech Operated Rel~a. Autospectra were computed for movements and speech at various bands and for various degrees of freedom by spectral analysis. Croos spectra for sppech/movement relationship for original and demodulated forms of the series were obtained. Series from 17 out of 63 recordings were used. The results show the psychotic group to have peaks in the low as well as in the high part of the movement spectrum. The group of Down's children also had peaks in the low part of the spectrum but these children showed a general incoherence over the whole speech/movement cross spectrum. We conclude that the low frequencies in the body movement behaviours of the psychotic group result from some aspect of therapist communication, but for the Down's group from an organic lethargy. The results for the unclassified are similar to those for the psychotic group but are different in some respects. The cross spectra are not highly significant, although mobility/speech coherence is greater for the psychotic than for the other two groups using the coherence of nonsense pairings as a base line. The number of subjects are low and do not allow of any firm generalizations.
