Questionnaire data were gathered from 82 investigators who had published comparative studies of Negro and white intelligence. The sample represented 64% of the population of researchers. 7 biographical items discriminated between 6 categories of conclusions drawn from research on racial intelligence (R = .4S), which included the following: There are no differences between Negroes and whites in intelligence; differences are due to environment; differences arc due to innate inferiority of Negroes. The 7 biographical variables were: age when research was published; birth order; whether grandparents were American or foreign born; mother's educational level; father's educational level; childhood in rural or urban community; and undergraduate scholastic standing.'Respondents as a percentage of 104 potential subjects to whom Questionnaires were sent: Category 1 (82%); 2 (82%) • 3;(60%)"; 4 (88%); S (0%); 6 (0%); 7 (100%); 8 (86%).
Four Air Force pilots were used as subjects to assess a battery of subjective and physiological workload measures in a flight simulation environment in which two computer-generated primary flight display configurations were evaluated. A high- and low-workload task was created by manipulating flight path complexity. Both SWAT and the NASA-TLX were shown to be effective in differentiating the high and low workload path conditions. Physiological measures were inconclusive. A battery of workload measures continues to be necessary for an understanding of the data. Based on workload, opinion, and performance data, it is fruitful to pursue research with a primary flight display and a horizontal situation display integrated into a single display.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
