q2 i? Taken as a whole, psychological methods (esthesiometry, computation, memory-span, cancellation, completion, continuous-work methods) can afford useful average values and reliable information concerning the course and effect of fatigue. → G. M. W 1910

q2 · i? · review · r2

The review reports Offner's conclusion (p. 35) about psychological measurement methods, including the continuous-work method favored by Kraepelin and followers, that they can "assist us directly in the regulation of our work." No effect sizes are printed.

"the psychological methods can afford useful average values and reliable information concerning the course and effect of fatigue, and can. accordingly, assist us directly in the regulation of our work"

Discussion¶

Related Claims¶

• Fatigue depends on age, sex, lesson length and number, time of day, weekday, recesses, holidays, rest, sleep, nature of work, school program, and teacher personality (Offner's laws of fatigue) — related
• Subjective symptoms are an unreliable measure of fatigue, and physiological tests have not yet yielded a reliable measurement method (Offner) — related
• Improvement by practice continues in both morning and afternoon groups, but the morning group improves faster across weeks — a narrower finding that bears on this claim
• In one class of 13-year-old boys, memory scores were kept to a steady rank order by repeated practice (successive tests correlating +.87 to +.90) before fatigue testing began — related
• Efficiency in the work curve is conditioned by factors beyond fatigue proper: practice, adaptation, preparedness, warming up, spurts, voluntary effort, ennui, and diurnal rhythms (Offner) — related
• Test-retest correlations of memory span are low, questioning the validity of a single memory span test — reports the opposite
• Late-afternoon memory work shows relative inefficiency of about 5-6 per cent compared with early-morning work in 13-year-old boys — a narrower finding that bears on this claim
• Across repeated digit tests pupils improved with practice, with large uniform increases attributed to unconscious memory of the previous day's digits, and no fatigue effect on recall was found — related
• Studies on the mental fatigue of school children assist in arranging the daily program, including order of subjects and recess periods — related
• Subjective fatigue states under prolonged mental work included failure to hold and banish partial products, lethargy, and labored breathing — a narrower finding that bears on this claim
• During the final fatigue test, time per problem rose gradually, then markedly, with no obvious correlation between time and accuracy — a narrower finding that bears on this claim
