12 years separate these two pictures, and in the meantime we moved from Maître de Conférences (assistant professor) to Professor. The big difference? We lost the French style! ^^

Was looking into what Cognitive Scientists mean by ‘domain-general’ cognition, and then hit upon this. This is definitely NOT how we use that term. Tip: read the last sentence to understand what went wrong here. Sigh.
Domain-General Cognitive Ability
In subject area: Psychology
Domain-general cognitive abilities refer to cognitive skills that are not unique to humans but are present across various primate species and potentially other mammals and birds, indicating a general factor underlying cognitive performance that correlates with brain size and is associated with selective attention and working memory capacity.

A badge designed for Registered Reports, following the same style as the OSF badges. It features a clean design with a green color scheme, consistent with OSF's visual identity. The badge includes the text 'Registered Report' prominently, framed within a circular or rectangular border for a cohesive and recognizable look. It is a picture PNG with transparency (not a vector).
