The study of personality requires that we understand what we mean by the te
rms personality and development. Whereas the concept of personality-includi
ng individual characteristics that are consistent over concert and time-is
appealing, serious issues in regard to consistency of characteristics over
different contexts and over time remain, suggesting to me that although cor
relations may be significant, there is relatively little variance accounted
for. As such, there is little consistency. The study of human development
also has difficulties, especially the idea that earlier events lead to or c
an predict later events. In this article, these 2 classes of difficulties a
re addressed. The data suggest that individual characteristics, especially
in children, are not consistent over context and time, and that earlier eve
nts do not predict later ones. This leads to the conclusion that an analysi
s of behavior in context may be the best way to understand the changing nat
ure of personality growth and development.
