The Proteus Effect: Impact of embodied avatar representations on cognitive and motor performances

The Proteus effect is a phenomenon by which an individual's behavior and attitudes are influenced by the characteristics of the embodied avatar (Ratan et al., 2019). Assimilation effect to the characteristics of the avatar have been observed in various contexts of incorporation and in different types of avatars (e.g. elderly avatar, black avatar, tall avatar, attractive avatar, Peck et al., 2013; Reinhard et al., 2019; Yoo et al., 2015).
Several theoretical explanations for this phenomenon have been proposed (Ratan et al. 2019). Proteus effect can be explained by modifications in self-perception (Yee & Bailenson, 2007), by a priming effect (Peña et al., 2009) or by the implication of both self-perception and priming effect (Ratan et al., 2019).
The objective of the thesis is to continue the investigation of the Proteus effect on motor and cognitive skills by focusing on the identification of the components of performance most impacted by the Proteus effect. This new data would provide a better understanding of the mechanisms and an integrated explanation of the Proteus effect.
The different theoretical interpretations of the Proteus effect proposed in the literature will be examined by varying and measuring the involvement of the assumed processes and variables (e.g., priming effect due to exposure to stereotype, self-perception).
