Abstract
|
"From the data reported the following points may be made: 1. A previously neutral token which had been a manipulandum in a token-reward sequence was overestimated more often than it was before it was placed in that sequence. 2. Experimental extinction tended to reduce significantly such overestimation. 3. When two previously neutral tokens were placed in the sequence so that they were at different distances from the reinforcement, the token closer to the goal tended to become overestimated as a result of such placement but the one farther from the goal tended to remain neutral."
