An experimental study of maze learning ability after varying periods of wakefulness.

Abstract

A 14-unit multiple-T water maze was used to measure the learning ability of white rats after 8, 16, 24 and 48 hrs. of wakefulness. The animals were kept awake by being picked up, handled or transferred between cages. Group comparisons are given. Following wakefulness there was an increase in learning efficiency of from 10 to 21%, varying with the interval of wakefulness and the method of measuring efficiency (errors, time, and trials). There was only a slight positive relation between the efficiency of learning and the amt. of wakefulness. By use of Vincent-Kjerstad curves the 16 hr. wakefulness group was compared to a normal group. In the early stages of learning the wakeful group took a higher % of their total time but made a lower % of their total errors than did the normal group.
