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)
Ontario, and Economist, OECD Development Centre. They wish to acknowledge their intellectual debt to the numerous Ghanaian academics, business leaders, officials, and others who gave so generously of their time in providing information. The assistance of Julie Ong in preparing some of the charts is also appreciated. The authors are very grateful to(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)
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)
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)
Test-retest reliability and sex differences when viewed in a distorted room were investigated. The presence of the Honi phenomenon, which is less change in apparent size of a spouse than of a stranger, was examined. A reliability coefficient was obtained by testing 27 college men twice. Judgments of size from 25 of the men and 25 women who viewed black disc(More)
