Abstract
Apple Picker, a software package for the Apple II microcomputer, is described. Subjects respond by searching for “apples” in two “orchards.” “Attempted pickings” may be reinforced according to random ratio or interval schedules. “Search” responses are recorded and may be examined either as rates of responding in the two orchards or visually as paths the subject has traced during the session.
