“…The general endeavor seems to be to establish a correlation between "respiratory arhythmias" and different niveaux of consciousness, but the paper is condensed to obscurity. Kiippers' (11) paper reporting plethysmographic work with dementia prsecox cases begins with a critical review of the previous studies, including the names of Brahn, Gent, Zoneff and Meumann, Lombard and Pillsbury, Shepard, and others, psychological rather than technical, and on the whole favorable to the method. In his experiments, respiration was recorded with a pneumograph of ordinary pattern.…”

Among the studies in psychopathology involving general experimental series, Rowland (17) contributes a brief, condensed note on her observations with normal subjects and delinquent girls. In simple reaction time as measured by Vernier chronoscope, more of these subjects gave slow times than would be expected in normal individuals. Another test was of formal memory, noting the number of repetitions necessary for learning by heart a series of nonsense syllables, with both visual and auditory presentation. Of the 35 subjects, 17 failed to memorize the auditory list in 25 trials, 11 failed in the visual test after trial, 7 without trial. 19 failed to reach the standard of normality in remembering what had been seen on cards exposed for three seconds. Burnett's test of distraction (simple maze and maze with distracting pictures) gave a performance regarded as subnormal in 14 cases. 16 failed to reach the normal standard in counting the number of times a letter occurred in a given passage. There were also three simple tests of suggestibility. Failure in six of the nine tests was deemed a subnormal record, and these records corresponded well with the official estimate of the capacities of the subjects. A comparative table at the close gives the number of cases in which the tests were "passed" by the Bedford group, 35 Mt. Holyoke students, and 35 Amherst students. The difference in favor of the college students is marked throughout, least in simple reaction time, and greatest in the auditory memory and "attention" tests. E. K. Strong (19) adds another to the much needed researches
