It was hypothesized that (a) if attending and correct responses were followed by approving attention from the staff, then the rates of attending and giving correct responses would significantly increase; (b) if yelling, rocking, and hitting were immediately followed by a command to stop, or by placement in a time-out room, then the rates of those behaviors would significantly decrease; and (c) if the above conditioning procedures were dropped, then the rates of all behaviors under study would return toward their operant levels.
