Facilitative
CAREGIVER TECHNIQUES
yes-and-ing a child’s interest
Elaborative
CAREGIVER TECHNIQUES
pointing and checking to see if the kid has latched to the idea
Initiating
CAREGIVER TECHNIQUES
instructing (ie, telling kid to eat)
control
4 types of modifications caregivers do to prime child for communication time

When it comes to priming a child for communication, what is state-setting?
manipulate infant’s environment to optimize interaction (ie gaining attention by coming to kid, making noises)
