Corsi's Block-Tapping Test: Standardization and Concurrent Validity with WISC—R for Children Aged 11 to 16

Corsi's block-tapping test and WISC-R were given to 1122 children from 11 to 16 years of age. Corsi's raw scores were transformed into standard scores like those for the WISC-R subtests. Reliabilities, standard score equivalents of raw scores, correlations with scores on WISC-R subtests, scales and factor scores are presented. A Principal Factor analysis of intercorrelations for Corsi's test and WISC-R subtests shows a three-factor solution with Corsi's test loading on the Third Factor. Results agree with Wielkiewicz's (1990) hypothesis about the construct underlying WISC-R Third Factor as "executive" and short-term memory processes.
