Three approaches to the study of infant temperament

Abstract

In temperament research, the sensitive quantification of individual differences is critical, and biases affecting temperament measures differ somewhat from those affecting normative studies of development. In this paper, we attempt to specify major biases and strengths of the three methods most widely used in the assessment of infant temperament: parent report, home observation, and laboratory observation. We also describe an ongoing research program in order to illustrate how potential biases may be negotiated. We conclude that choice of temperament measure or measures depends upon (a) the purpose of the assessment, (b) knowledge of empirical relations among methods, and (c) evaluations of the seriousness of potential measurement biases.
