Table 2 1, Excerpt of an M/R training session, 1/20/81. The aim of the
session was to review and improve pronunciation of the label "five."
B refers to Bruce Rosen, one of the secondary trainers, I to the principal
trainer (me), and A to the parrot Alex. This portion of the session lasted
approximately 5 minutes. (After Pepperberg 1988a)

I:	That's right, five wood. Here you are ... Five wood. (hands over five
	wooden craft sticks. B begins to break one apart, much as Alex would.)
A:	'ii wood.
B:	(Now acting as trainer, quickly replaces broken stick and presents the
	five sticks to Alex): Better ... (briefly turns away, then repositions
	himself in visual contact with Alex) ... how many?
