De Lauretis's account of subjectivity as a product of "being subject/ed to semiosis" (i.e., making meanings and being made by them) helps to theoretically resolve and overcome the tension between human action (agency) and structure. She made use of
Umberto Eco's reading of
C.S. Peirce to establish her notion of the semiotics of experience. She brought corporeality back to the discourse on the constitution of subjectivity, which has been conceived mainly in linguistic terms. Her semiotics is not just the semiotics of language but also the semiotics of visual images and non-verbal practices. Her (Peircean) "habit" or "habit-change" is often compared to
Bourdieu's notion of
habitus.
Michel Foucault's analysis of the body excludes the consideration of the specificity of the female body that many feminists have criticized. Supplementing the failure, gender should be one of the effects of technology, which renders the basic intelligibility of the body, and that turns to De Lauretis's "technology of gender". De Lauretis coined the term "
queer theory" although how it is used today differs from what she originally suggested by the term. She coined the term in February 1990 at a conference at the University of California, Santa Cruz, whose proceedings were collected in a 1991 special issue of
Differences: A Journal of Feminist Cultural Studies. She suggested that queer studies should be studied separately from lesbian and gay studies. De Lauretis stated that "queer theory challenged norms" that enforce inequalities regarding "social identities" such as gender, sexuality, class, and race. ==Honours, awards and grants==
