Abstract
A simplex process model of the cross-lagged correlation
paradigm was applied to 16 tests administered
to samples of black and white males and
black and white females in Grades 5, 7, 9, and 11.
Listening, a measure of aural comprehension, consistently
anticipated individual differences on an intellectual
composite in all four groups. The other
achievement test of the STEP series anticipated individual
differences on the so-called aptitude tests
of SCAT, which in turn anticipated individual differences
on the narrow information scores obtained
from the Test of General Information (TGI). This
model may be more powerful in revealing lags than
the traditional methods of analyzing cross-lagged
differences in longitudinal data. The model does
not require stationarity and can produce a
meaningful outcome in its absence.
