. The effect of length of blind alleys on maze learning: an experiment on twenty-four white rates. Rats; Animal intelligence. 24 JOSEPH PETERSON Three important features of the results are to be noted. The first is the rapid decrease in the proportion of the returns to forward runs, on the rat's emergence from blind alleys. With the exception of blind alleys 2 and 5 in the B-mazes few such returns were made after the 15th trial, though the animals continued to enter some of the blind alleys beyond the 75th, some even beyond the 100th. These cul de sacs, noted as AVERAGE PER TRIAL PERIOD. t-5 6
