Automatic Processes and Implicit Cognition

My first research area deals with automatic processes. For instance, we showed that alcohol related primes automatically induces aggressive thoughts and aggressive behavior (Subra, Muller, Bègue, Bushman, & Delmas, 2011). Together with François Ric, we also showed that one can perform additions totally unconsciously, that is without knowing he/she does and without even seeing consciously the to be added-digits (Ric & Muller, 2012). We also revisited the cocktail party effect by studying systematically the 3 remaining (Bargh, 1982 having convincingly demonstrated one of them) features of automaticity (Alexopoulos, Muller, Ric, & Marendaz, 2012). I now study a grounded cognition approach to memory processes. We showed that it is possible to mask auditive information with a visual mask and possible to mask visual information with a sound (Rey, Riou, Muller, Dabic, & Versace, 2015). In addition, we applied a grounded cognition framework to the development of an approach/avoidance measure, the Visual Approach/Avoidance by the Self Task (VAAST; Rougier et al., 2018). We also showed that this task replicated very well, even online (Aubé et al., 2019). Finally, we started to investigate whether this task could be used as a measure of intergroup attitudes (Rougier et al., 2020) and as an approach/avoidance manipulation (Batailler et al., 2021).

Social Comparison Processes

My second research area dealt with social comparison processes. More precisely, my major theoretical interest is on the study of social factors' impact on cognitive processes. Hence, we study notably the impact of coaction and social comparison (at an interindividual level and at an intergroup level) on visual processing and attention (Muller, Atzeni, & Butera, 2004; Muller & Butera, 2007). The aim of these researches is on the one hand to study how and when social context can help information processing and on the other hand to understand better the way social context moderates cognitive functioning. More recently, we studied the impact of grounded cognition on how social comparison influences self-evaluation (Fayant, Muller, Nurra, Alexopoulos, & Palluel-Germain, 2011) as well as the impact of social comparison on aggressive behavior (Muller, Bushman, Subra, & Ceaux, 2012).

Data Analysis

My third area of research interest is about data analysis methods. Our current research deals with the adjustment function within regression models. This function is notably implied in what is known as ANCOVA models (Yzerbyt, Muller, & Judd, 2004) and mediation analyses (Muller, Judd, & Yzerbyt, 2005; Muller, Yzerbyt, & Judd, 2008; Yzerbyt, Muller, Batailler, & Judd, 2018).
