About this Lecture


In this lecture, we think about theory as a psychological model which argues that our social connections are an important aspect of who we are, focusing in particular on: (i) how the dynamics between the ‘ingroups’ to which we belong and the ‘outgroups’ from which we distance ourselves can lead to prejudice in an intergroup context; (ii) the common ingroup identity model as a way of reducing prejudice between groups; (iii) a study which underlines the importance of maintaining subgroup distinctiveness in order to avoid prejudice.


In this course, Dr Juliet Wakefield (Nottingham Trent University) discusses prejudice, stereotyping and discrimination. In the first lecture, we look at a definition of these three concepts. In the second lecture, we explore some social psychological explanations for prejudice, focusing in particular on the ‘authoritarian personality’ and realistic conflict theory. In the third lecture, we think about a classic study exploring the latter – Sherif’s Robbers Cave study. Next, we focus on social identity theory as a way of explaining how ingroup-outgroup dynamics can serve to fuel prejudice. In the fifth lecture, we think about a specific target of prejudice by considering sexism or gender discrimination. In the sixth and final lecture, we look at the potential effects of stereotyping, prejudice and discrimination on those targeted and their wider communities.
