rMEA: An R package to assess nonverbal synchronization in motion energy analysis time-series

摘要

Recent studies used MEA to investigate nonverbal synchrony, i.e., the occurrence of simultaneous movement, suggesting the existence of an association with relationship quality. In patient-therapist dyads, synchrony predicted therapeutic alliance, empathy, as well as treatment outcome. Package description
