Stress depletes cognitive resources and narrows how people perceive their in-groups

Evidence

Roccas and Brewer (2002) have suggested that individual variations in social identity complexity may depend on a range of additional antecedents, such as values, mood, or stress. For example, they argue that since stress is known to deplete cognitive resources and lead to a narrowed focus of attention (Easterbrook, 1959), it may also lead to less complex and less differentiated multiple in-group perceptions. — Roderick M.
