title: Generalizability Of Free-Recall Measurements.
abstract: This study investigated the generalizability of free-recall measurements. Subjects were 55 fifth-grade pupils, who completed ten trials of recalling familiar nouns plus two summary trials. The observation conditions included two list lengths (20 and 30 words), two rates of presentation (1 1/2 and 2 1/4 seconds per word), and two occasions (two weeks apart). Alpha factor analysis indicated that (1) the measurement procedures may be conceived of as derived from a single domain; (2) the homogeneity of the domain is estimated to be .64 for experienced subjects; (3) generalizability is greater with experienced subjects; and (4) the use of a summary trial is a simple way to increase the generalizability of a particular measurement procedure. The generalizability achieved by totaling performance over selected number of trials is estimated separately for naive and for experienced subjects.
