Combining Recurrence Analysis and Automatic Movement Extraction from Video Recordings to Study Behavioral Coupling in Face-to-Face Parent-Child Interactions.

The test showed that the full model is highly significant for both analyses compared to the additive only model [detailed coordinate system: χ ( 50 ) 2 = 234.54, p < 0.001, V = 0.52; simple coordinate system: χ ( 50 ) 2 = 287.39; p < 0.001, V = 0.47], which in turn is also highly significant compared to the null model [detailed coordinate system: χ ( 51 ) 2 = 220.14, p < 0.001, V = 0.45; simple coordinate system: χ ( 51 ) 2 = 6832.17, p < 0.001, V = 2.55].
