摘要: Abstract Rats received runway training under alternating reward and nonreward in which rewarded (R) trials provided 32 or 4% sucrose concentration from a drinking tube nonrewarded (N) dry or, for half of the rats 32% condition, plain water. Both concentrations yielded faster running on R than N trials; but this effect was reliable only condition. Compared to sucrose, reliably slower unreliably trials.
