Abstract

Five high school students, who had no knowledge of German, learned the English equivalents of 850 German words in one sitting of about four hours. Each pair of words was presented four times. Two days later recognition, recall and retention tests were given to determine the persistence of the associations. The curve of learning efficiency remains practically level. There is a slight drop in the middle, followed by a slight rise at the end. Of the material learned in the latter part of the experiment eighteen per cent. less is retained than of that learned in the first part. Recognition of the material used in the early part of the learning period is much superior to that of material used in the latter part. This indicates that adaptation to fatigue involves a narrowing of neural activity to the specific process demanding adaptation. From Psych Bulletin 18:06:00347.
