content: This apparatus tested the ability of children to generalize. Paper tapes of pairs of pictures were shown to the child being tested, who then selected the "correct" member of each pair. There were twenty pairs altogether. The tapes were mounted on a drum operated by two response keys, one for pictures on the left, one for those on the right. Pressing the "correct" response caused the drum to go forward and a green light to flash. "Incorrect" responses caused a flash of red light.
