INTERPELLATION In Althusser's theory of ideology, interpellation is the mechanism that produces subjects in such a way that they recognize their own existence in terms of the dominant ideology of the society in which they live. (1970).
According to Althusser, the idea of interpellation demonstrates that subjects are always and already the products of ideology, and thus subverts the idealist thesis that subjectivity is primary or self-founding.
Confronted by the flow of signs and images that cosntitute Debord's 'society of the spectacle', individuals are constantly interpellated by posters, advertisements and stereotypes offering universal images in which they are invited to recognize themselves.
Whether or not there is any direct connection between the two notions of interpellation remains unclear.
