Copying alpha and numeric codes by hand: An experimental study

Abstract

DIFFERENT GROUPS OF HOUSEWIVES COPIED ALPHABETIC AND NUMERIC CODES BY HAND UNDER 5 DIFFERENT CONDITIONS. FACTORS SUBSTANTIALLY AFFECTING SPEED OR ACCURACY OF COPYING OR BOTH WERE: CODE LENGTH, DISTANCE BETWEEN ORIGINAL AND COPIED CODE, WHETHER THE CODE WAS ALPHABETIC OR NUMERIC, AND, FOR 12-DIGIT CODES, GROUPING OF DIGITS. ANALYSIS OF COPYING ERRORS POINTED TO A MARKED SHORT-TERM MEMORY COMPONENT, AND THIS CONCLUSION IS SUPPORTED BY THE SIMILARITY BETWEEN THE PRESENT RESULTS AND THOSE REPORTED FROM CONVENTIONAL SHORT-TERM MEMORY STUDIES.
