Dark Adaptation Studies with Adults and Children, Using the Biophotometer

Date: 1942
Creator: Collins, Mary Margaret
Description: The present study is a part of a long-time cooperative study of the Home Economics Department of the North Texas State Teachers College, begun in 1940. The purpose is to compare the dark adaptations of second and third-grade children made in 1940 with those made of the same children in 1941 and in 1942. Also included in this study is the comparison of a group of freshmen college men made in 1940 with a group of twenty-five men made in 1942. An attempt is also made to determine whether an individual has higher dark adaptation on sunshiny days than on cloudy days.
