In this address, I consider the realized and potential contributions of sociological social psychology to research on inequality based on invisible disabilities and the challenges that invisible disabilities pose to current social psychological theories. Drawing from the social structure and personality framework, I advance the general notion of invisible disability as a dimension of inequality, consider how four basic social psychological processes (social categorization, identity, status, and stigmatization) have and can help us understand how invisible disabilities shape outcomes over the life course, and suggest new lines of research social psychologists could pursue. I close with brief comments about the benefits of such an agenda for sociological social psychology as well as how these lines of research can inform theories of stratification.
