Navigating the normativity of behaviour settings: an observational case study.

Traditionally, sensitivity to situational norms is understood as deriving from internal cognitive states that represent the rules for appropriate conduct. On an alternative view, norms are 'out there', in the practices and situations themselves, without being duplicated in the head. However, what does normativity look like when it is performed by people engaging with a concrete situation? A 'behaviour setting' offers a window onto these dynamics. This article presents an observational case study of normative coordination within a behaviour setting. Immersed in a scientific laboratory setting, the observations show how the normative demands of the overall behaviour setting can give shape to various places of action, or 'synomorphs', which invite the participants' activities. Responding to the different needs of each synomorph, in turn, maintains the behaviour setting. What connects these two reciprocal timescales of activity are the situationally sensitive activities of the participants. We end with several examples that bring such sensitivity to the interdependence of the norms of a behaviour setting to the fore. This article is part of the theme issue 'People, places, things, and communities: expanding behaviour settings theory in the twenty-first century'.
