These students arc doing psychological experiments with rats in conditioning boxes. In two of the boxes the rats have been for twenty-four hours, hence, a drink water will bo a 'reward'. To receive ttiis, the rat must step on a bar in the box The rats in each of these boxes have been conditioned; that is, they realize the consequence of stepping on the bar. The students are trying tu determine what will happen il the rat is only rewarded every second time he stops on the bar, then every third time and so on. Will the rat persist, and in the human situation will an individual work hard lor rewards not seen? In the third box (at the left, closest to the camera) students arc trying to condition tire rat so that he will stand on the bar to stop the electric current from giving him a shock. There was a smart rat in that box; he just sat on the bar. The aljovc was constructed by some of tlic students in the class. Ilic rat receives awards when lie has threaded his way tUrough the complex of passage- ways.
