Abstract

To examine the possibility that position cues are temporal and
therefore ineffective early in serial runway training, rats were runway
trained on a three-trial series of different rewards. The series was
SNP', where Sand P' refer to series trials that concluded with four
sucrose or eight plain Noyes pellets, respectively. The middle trial
was never rewarded (N). Early in training, a significant pattern of
running slowly on the middle trial and rapidly on the initial and
terminal trials had emerged. Transfer tests to series of trials (NNN)
never rewarded after this limited training (on Day 19) and later after
extended training (Day 39), each gave evidence that the rats relied
upon position cues in the tests. The three-trial patterns established
before the tests were retained on the three trials of the NNN series.
The results suggest the prevalence of position learning, but they work
against the idea that position cues are temporal and effective only
with extended training.
