Three types of eye movements, saccadic, reading, and pursuit, were recorded from 6 college subjects, two in each by the electrooculographic and photoelectric methods simultaneously. A deviation index (DI), which is the standard deviation divided by the mean, was devised to compare the precision of recording amplitude deflection, and a proportion index (PI),(More)
Relationships between Memory-for-Designs test, Wechsler Intelligence Scale for Children (WISC), and Wide Range Achievement Test (WRAT) were determined for classes of 12 and 14 educable mentally retarded children. Rank-difference rs showed that Memory-for-Designs errors correlated significantly with WISC Verbal IQs (-0.78), WISC Performance IQs (-0.85), and(More)
A Beckman Type RM Dynograph was used to record the eye movements of 26 professional college men, once without spectacle corrections and then with plano lenses on a trial frame, during reading equivalent print at a distance of 33 cm. Amplitudes of the return-sweep velocity on these two trials were used to calculate an equivalent form reliability coefficient.(More)
The onset and terminal stages of presbyopia, the loss of amplitude of accommodation of the eye associated with old age, of the Southeastern Asian refugees were investigated. Subjects examined in a 6-mo. period in an optometric practice are included. A +1.00 D add was used to define onset of presbyopia, and +2.00 to 2.50 D, the terminal stage. Only those age(More)
A Beckman Type RM Dynograph was used to record eye movements of 31 college students, 23 of whom had never worn contact lenses and 8 who had worn contact lenses for at least five years and 12 hours a day, while reading equivalent print at a distance of 33 cm. Analysis showed that the deviation indexes of .28 and .26 were comparable, meaning that these two(More)
