In this response to McCartney and Black (1995), the point is made that
our purpose in presenting the two-tiered approach to classifying the
acts and conditions of caregiving was to offer a framework that was mo
re in keeping with current ecological developmental theories than most
other approaches to measuring or classifying the elements of caregivi
ng. Their idea of constructing a system that could reliably capture al
l the dynamic features of transactions, including a child's subjective
responses, although laudatory, seems very difficult to achieve. Thus,
the proposed approach focuses on an objective system of classificatio
n that moves in the direction of capturing the dynamics of transaction
s while still meeting scientific criteria for reliable placement into
categories. The argument is made that scientifically useful descriptio
ns of caregiving environments can be attained using a systematic, obje
ctive approach to classifying acts and conditions of the environment e
ven while recognizing that all children do not respond the same to tho
se acts and conditions. (C) 1995 Academic Press, Inc.
