Self-perception theory and cognitive dissonance theory have depended
on both explicit memory and conscious processing to differing degrees in their explanations of attitude change. Although the current
data do not address either theory’s general viability, they do suggest
that the processing components of these theories need clearer speciﬁcation. Future research integrating the methods of neuroscience into
social cognition should yield clearer speciﬁcation of these processes
