It was just called to my attention that in the “check” I gave you initially in the CHILDES lab description, I suggested that I found 18 of the first verb, and 24 of the second verb (for Part 2). It’s actually 24 for each of them (I missed 6 initially when I wrote that up).
In the CHILDES lab, one of the early steps is to pick a verb that is used a lot (as reported by freq). The idea was to pick the most common verb, except have, go, want, and see. Although it’s maybe giving away something that I wanted to you answer, just to keep us on …
In response to a question I got about part 6 of the CHILDES lab (where you are to count up the wh-questions): What we’re counting here should be just the cases where the child utters a wh-question (not cases where the child is responding to a wh-question).
