Experimental analyses of human sexual arousal have been decidedly spar
se. Recent developments in the analysis of derived relational respondi
ng, however, have opened the way for a modern behavior-analytic treatm
ent of complex or ''novel'' human behavior, including specific instanc
es of human sexual arousal. The current article examines some of these
developments and their relevance to the analysis of emotional behavio
r, with a focus on sexual arousal. Recent research that has examined t
he acquisition of sexual stimulus functions within a relational frame
paradigm is then outlined. Finally, a series of relational frame inter
pretations of a variety of human sexual arousal phenomena is offered.
