C. Tinajero et al., Comparative analysis of different correction methods for measuring Rod-and-Frame Test performance, PERC MOT SK, 90(1), 2000, pp. 93-101
A comparative analysis was conducted of five different methods for scoring
the Rod-and-Frame Test to examine the convergent validities of each of the
five methods with performance on the Embedded Figures Test for a sample of
408 13- to 16-yr.-olds. The scoring methods included the absolute error, th
e algebraic error, the absolute value of the algebraic error, the frame eff
ect, and an assessment of relative field dependence. Correlations obtained
among the five methods and the Embedded Figures Test indicated different pa
tterns for boys and girls. In general, the method which employed the absolu
te Value of the algebraic error yielded the strongest convergent validity c
oefficients with scores on the Embedded Figures Test and Group Embedded Fig
ures Test for boys (.62 and -.54, respectively), although, for girls, the a
bsolute algebraic error and absolute error both yielded coefficients of .50
with Embedded Figures Test scores and -.46 with Group Embedded Figures Tes
t scores.
