Abstract
The present study is an exploratory study of the applicability of motion energy analysis (MEA) in a
naturalistic therapeutic setting where we follow 6 children with communication problem during their
treatment sessions. The therapy under scrutiny is based on the principle that if children fail to learn to
synchronize in a healthy manner, by either being almost always out- or almost always in-sync, behavioural
problems arise. MEA is a recently developed observer-independent procedure, that uses differences in
grey-scale pixels for detecting frame-by-frame changes in pre-defined regions. MAE was used to collect
data on the movement intensity of the client and the therapist. The MEA data was further analyzed with
cross recurrence quantification analyses (CRQA). CRQA measures were compared to global treatment
goals and we found that MEA is a viable instrumental tool in measuring the synchronization of nonverbal
communication in a naturalistic therapeutic setting.
