Moment-to-moment cascades: Infants' real-time locomotor posture structures opportunities for joint object play with caregivers.

-the view that development in one domain can induce change in another-provide unique flexibility for researchers to examine relations among multiple behaviors. Research using this theoretical framework has demonstrated that changes in infant locomotor development are met with concomitant changes in infants' interactions with objects and caregivers. However, little is known about how infants' real-time locomotor actions organize these larger associations across developmental time.
