Mila and Mommy High-5
In this video, Mila’s mother asks her for a high-5. Notice that first the mother calls her name and waits for her to turn towards her. She then gives the instruction “give me a high-5” and holds her hand up as a model, which could be considered a prompt —or it could be considered the sD (discriminative stimulus). Either way, notice how Mila’s mother holds her hand still and Mila is the one to reach out to give the high-5. After the high-5, Mila’s mother offers praise (and I imagine a smile). Mila coos at the end, seemingly approving of their interaction.
