Parisian Laboratory of Social Psychology (LAPPS in French)

Created in 2009, the Parisian Laboratory of Social Psychology (LAPPS in French) is a Francilien research unit under the double tutelage of the Paris Nanterre University and the Paris 8 University.

The LAPPS aims to understand how individuals mobilize, more or less consciously, cognitive, affective and motivational resources to accomplish their activities in a normative context. The unit has a dual fundamental and applied orientation. On the one hand, a fundamental orientation oriented towards the modeling of socio-cognitive processes (stereotypes, intergroup relations, organizational justice, etc.), processes associated with behavioral change (habits, cognitive dissonance, etc.) and processes associated with transitions and professional adjustments throughout life. On the other hand, applied research contributes to individual and collective issues in the framework of strategic partnerships beyond academia (health, environment, consumption, organizations, work, etc.).

The LAPPS is divided in 3 research teams:
