Joey asks the group to help think about what drives children's seemingly mindless tapping and hitting of objects. Does it provide sensory input or an energy release? Is it just a form of fidgeting? Does it help children focus or regulate? Perhaps it helps them figure out who they are in relation to their environment? Along the way, Tom and Ross engage in a friendly debate about whether children are "always moving." Mike cautions to watch out for bias against so-called mindless activities.
