Show Summary Details


This chapter describes the pilot studies that led to the selection and validation of the measures used in the Seattle Longitudinal Study. The 1956 baseline study is presented and its findings are compared with the six cross-sectional replications. For purposes of an orderly presentation, the basic cognitive battery that is common to all study cycles is analyzed. Data for the fifth, sixth, and seventh cycles for the extended cognitive battery and the practical intelligence measures are then presented. Finally, the cross-sectional findings for the measures of cognitive style (Test of Behavioral Rigidity, TBR) are discussed.
