Mushroom ketchup footage and commentary

In this clip my objective is to set up our interaction so that P checks in with me (references) to make sure that his actions are synchronised with mine, and takes corrective action if they aren't. Here is where he checks in:
0.15 secs; 0.26 secs; 0.36 secs;
0.40 secs
0.58 secs
1.03
1.24
1.46
As you can see, we need some new light bulbs!
We are using the intervention Relationship Development Intervention (RDI) to help P develop flexible, adaptive thinking, addressing the rigidity that is at the heart of autism.
