A central proposition of Gottfredson and Hirschi's (1990) General Theory of Crime is the relative stability of low self-control, however research on "self-control strength" suggests that it may vary across contexts. The current study examines these differing conceptions by randomly assigning participants to one of two sexual arousal conditions or to a no-arousal condition. Group differences in the six components of self-control, as captured on the Grasmick et al. (1993) scale were then examined. Unexpectedly, individuals in the most intense arousal condition actually reported higher self-control than those in the other conditions (both in absolute value and in changes in relative rank within the sample). Such findings provide additional empirical support for the recent conceptualization of self-control strength as a personal characteristic that can be both exercised and potentially depleted when overused.
