Reviews development and first two years' experiences of a laboratory course of inquiry into the nature and processes of American civilization through examination of local history as symptomatic history. Faculty, graduate fellows, and advanced undergraduates collaborated on research and analysis of the relationship of culture, environment, and…

Three studies are described in which choice reaction time (RT) was related to such psychometric ability measures as verbal comprehension, numerical reasoning, hidden figures, and progressive matrices tests. Fairly consistent negative correlations were found between these tests and choice RT when high school samples were used. (Author/CTM)
