摘要:Using the method and materials described in earlier work with C. P. Seitz (same Jour. 30(2): 1946), 12 subjects were tested for their ability to perceive speech sounds at 4 intervals during an 8-hr. exposure to mild anoxia in a nitrogen dilution chamber at simulated altitude of 10,000 ft. These subjects listened to recorded speech sounds played at a low level of intensity, and checked off the stimulus words on 4 separate tests containing check rows for 11 vowels and 24 conso1nants. The testing...

摘要:In this study, a multiple-choice checker test was used to test visual acuity of 400 subjects in an age range of 17-36 yrs. The subjects were required to locate a checkered test square by indicating its position relative to 4 other control squares. The apparatus was set up so that 8 levels of visual acuity could be obtained at distances of .20, .25, .33, .40, .50, 1.00, 5.00, and 10.00 meters. Illumination in the vicinity of the apparatus was under 1 foot candle, and on the target it was 8 foot...

摘要:Certain types of brain injuries are apt to be unaccompanied by appreciable symptoms of sensory and motor loss. Rather there will be subtle changes of intellectual deterioration, and alterations in the emotional life and personality of the individual. It is pointed out that the standard tech- niques used by physicians in the diagnosis of brain injury often fail to yield the crucial information needed for the vocational management of such individuals. There is a critical review of the best clini...

摘要:Twelve visual tests were administered to 3 employee groups. The groups, equated on amt. of schooling but differing in first aid records, were an accident-free group, a high-frequency-of-minor-accident group, and a serious-injury group. The complete set of tests given are incorporated in the Bausch and Lomb ortho-rater. Judging from critical ratios, the accident-free group was superior to the other 2 groups in 7 of the 12 tests. Not a single critical ratio met the criterion (2.03) for significa...

摘要:This inventory is a fresh attempt at the measurement of maladjusted trends in personality. Most tests of this type are cast in the form of questions, and are often difficult for a candidate to answer. In this list, brief descriptions of worry symptoms are set out in very simple, unambiguous terms. Subjects do 2 things: (1) underline all items which cause them to worry; (2) ring those items which are present worries. The 63-item list was given to 100 university students of both sexes ranging in...

摘要:The author surveys the literature to indicate that individuals express a wide range of preference for intensities of illumination as best for comfortable reading under general lighting. Failure to allow for adaptation between changes in intensities has been a common fault in many a previous study. Visual adaptation at the time of choice seems to play a large role in determining individual intensity preferences. The scope of the present report is narrow, being concerned with the effect of visua...

摘要:The belief is widespread that mixed eye-hand dominance, i.e., the tendency for eye and hand preference to be opposite sided, is a cause of reading disability, nervousness and behavior problems in children. A number of published studies report conflicting results. Further evidence bearing on this question was obtained through a survey of an elementary school population of 101 boys and 90 girls from kindergarten to Grade VI. Age ranged from 6 to 11 yrs. The population ranged above average in gen...

摘要:A group of 176 private school boys, between the ages of 13 yrs. and 17 yrs., 5 months, was somatotyped according to Sheldon''s procedure for the classification of physiques; e.g., Ectomorphy, Mesomorphy and Endomorphy. The typing was done by Sheldon by inspection of photographs, and the boys were grouped on the basis of similarity of physique into 9 to 22 groups. The analysis of variance (F values) was used to test whether the variables studied were related to the somatotype groups. Scholastic...

摘要:At the time of writing, the Hunt-Minnesota Test for Organic Brain Damage had been used routinely for 9 mos. on 68 neuropsychiatric patients. The great majority of these cases were diagnostic problems without clinically obvious deterioration but with suggestive histories or equivocal neuralogic signs of brain damage. In many instances, however, the psychologic examiner was unaware of the neurologic status of the patient. Performance on the test is expressed in terms of a T-Score (a standard sco...
