Abstract
The purpose of the present experiment is to study the cues, which will give some light upon the condition of learning in details. I carried out the investigation of the latent learning under the condition of a drive, which is weaker and more powerful than that of TOLMANS' group, that is, 12 hours drive by food deprivation. Then I used TOLMAN & GLEITMAN maze (13) and a method similar to that.
1. 16 rats were given equal reinforcement in both end boxes. But both end sections were very different in perceptual natures. After equal training on the two sides, the rats. were shocked in either of the end boxes of the sections.
2. Half of the rats were motivated 22 hours of food deprivation and the other half, 8 hours of the same deprivation.
3. In the test trial, one group which was given 22 hours of food deprivation, all avoided the goal boxes, in which they had been shocked, and this fact corresponded to the TOLMAN & GLEITMAN results, showing “latent learning” But the other group, which was given 8 hours of food deprivation, did not show distinctly the sign of avoiding the goal boxes, in which they had been shocked.
4. The results are discussed in connection with the TOLMAN & GLETTMAN (13) MINTURN (7), SEWARD (9), experiments.
5. I suppose that latent learning is difficult to find under such a weak condition of drive.
