In this project, we aim to understand how people switch between different aspects of the self that are related to important groups (“social identity switches”), whether these switches incur cognitive costs, and whether they can be initiated or avoided successfully.

While self-categorisation theory suggests that we perform frequent social identity switches in our everyday lives (Turner et al., 1987), little is known about how effective this process is. For instance, an employee might switch from an organisational identity to a parent identity in response to a phone call from their child, or a customer might switch to an activist identity in response to a contentious ad.

Our research addresses this gap in knowledge by:

(1) assessing whether social identity switches are effortless or incur “switch costs” similar to the costs reported for task switches

(2) examining how much control we have over such switches

Are identity switches effortless?

Based on paradigms used in task-switching research          (e.g., Rogers & Monsell, 1995; Meiran, 1996), the first two laboratory studies prompted and assessed several social identity switches in a within-subject design.

A study using IATs supports effective and relatively quick switches between identities by showing no effect of switching on the congruency effect:

Future studies will firstly aim to:

(a) replicate this finding


(b) test whether switches remain as effective when switching away from a novel as compared to an established identity


Can we control identity switches?

Self-categorisation theory, specifically meta-contrast theory, suggests that the social context determines which identity is salient at any given moment. Here, we examine whether salience is indeed entirely dependent on exogenous factors, or whether endogenous processes also play a role in inhibiting but also creating identity switches.


These questions are considered by Anna Zinn as part of her PhD project, supervised by Miriam Koschate-Reis, Aureliu Lavric and Mark Levine.
