Hierarchy is a defining feature of groups (Berger et al., 1972; Fiske, 2010; Sidanius & Pratto, 1999). In this thesis I examined what it takes to climb up this hierarchy in face-to-face groups. I did so from three angles: what people need to do in order to attain status, what kind of person people need to be in order to attain status, and what people may need to sacrifice in order to attain status. Moreover, I assessed the moderating effect on these relations of two fundamental processes underlying group hierarchies: dominance (i.e., assertively claiming status) and prestige (i.e., willingly being granted status). Before addressing the main questions of this thesis, I examined the impact of dominance and prestige processes on perceptions of group hierarchy types (Chapter 2). A vignette study found that assertively claiming status for oneself and willingly being granted status both emerged as viable ways of enhancing perceived status, above and beyond formal status. It also found that, at the group level, each type of process worked against the other: perceptions of each were undermined by mixing it with the other. This finding implies that groups can be classed along a hierarchy type continuum, ranging from highly dominance-based to highly prestige-based.

Having empirically established how dominance and prestige processes jointly shape the types of hierarchies that exist in groups, I addressed the main questions of this thesis in a series of experimental and naturalistic studies. In Chapter 3, I examined the interpersonal behaviours that promote status in different types of group hierarchies. I found that agentic behaviour promoted status both in dominance …
