Unlike Thorndike’s procedure that involved the use of ________, Skinner’s procedure allowed the subject the continual opportunity to respond. In Sniffy’s case, the ________ is the response device this is continually available.
a. trials; magazine
b. trials; bar
c. stages; magazine
d. stages; bar
b. trials; bar
Answer feedback: Skinner dispensed with trials procedures like those Thorndike used in favor of a continuously-available opportunity to respond. In the virtual chamber that Sniffy is exposed to, the response device is the bar. The magazine is located behind the rear wall (and is therefore unseen) and dispenses the food pellets.
