abstract="A continuation of work reported in this journal, 1925, 8, 363-380, to determine &quot;the effects of fatigue induced through loss of sleep on the learning process.&quot; 5 subjects worked, 3 as an experimental and 2 as a control group, tossing balls into a basket 12 feet distant, transcription on paper of a text into the Morse code, and mental multiplication of two two-place numbers. There was an 18-day pre-insomnia series, followed by 3 days of reduced sleep, and then 6 days post-insomnia. No sleep was taken on the 3 days by the experimental group (66 hours). The main differences noted were: inability to maintain attention for a period; decreased speed with little or no effect on accuracy; effect of sleep loss is immediate; time needed for recovery varies with individual--generally a single night; &quot;fatigue does not lessen ability, but affects… motivation, interests, initiative, attention and concentration, which are necessary to the learning process.&quot; No mention is made of Laslett's more extensive investigation reported previously in this journal.
