• The effects of sucrose concentration incentive and its shift upon runway performance and tongue pressure were investigated using 31 rats. The <I>S</I>s were first trained to run down an alley for either 20% (Group H) or 2% (Group L) of sucrose solution and then the concentrations were switched for half of the <I>S</I>s in each group. For the nonshift groups, the shift was introduced at the later stage of training. The following results were obtained, 1) Group H ran significantly faster and showed consistently stronger tongue pressure, though not significantly, than Group L. 2) The running speed significantly decreased and increased with decrement and increment of reward concentration, respectively. The tongue pressure also showed approximate parallelism with the running speed. 3) The changes in runway performance were significantly more rapid when the upward shift in concentration was introduced after 99 trials than after 60 trials.
