Zero-Order Correlations of RVC and an Alternative Possible Index of Child Vocal Reciprocity^† with the Probabilities of Their Component Behaviors and Consonant Inventory in Study 2

	Probability of AV	Probability of CV	Probability of CV→AV sequence	Consonant inventory
RVC	−.13	.51**	.24	.60**
Probability of occurrence of CV→AV→CV sequence†	.53**	.75**	.86**	.43

Note.

^**p < .01.

AV = adult vocalization. CV = child vocalization. → = followed by. RVC = reciprocal vocal contingency.

^†The alternative index does not control for chance sequencing of events.
