Where Is the Individual? Comments on Nesselroade, Gerstorf, Hardy and Ram
Schaie, K. Warner
Measurement: Interdisciplinary Research and Perspectives, v5 n4 p243-245 Dec 2007
Nesselroade, Gerstorf, Hardy, and Ram have done a marvelous job in discussing the methodological issues for a meaningful revival of the idiographic versus nomothetic debate that has flared up periodically over the past seven decades. Nesselroade et al. have previously attempted to resolve the paradox that all behavior occurs at the individual level but that scientific generalizations can only be made for populations of individuals by emphasizing the important role of P-technique factor analysis (e.g., Nesselroade, 2006; Nesselroade & Ford, 1985). In their present article Nesselroade et al. show more explicitly how concepts of intra- and interindividual variance can be utilized to treat the generalizability of sets of individual factor patterns at the second-order level. In this commentary, the author's major concern is that while the idiopathic characteristics of the individual may be filtered appropriately with respect to a single psychological domain, other possibly more important individual characteristics are likely to be obscured. Nevertheless, Nesselroade et al. make an important step forward and are likely to revive interest in the idiopathic/nomothetic debate.
