The Roles of Time and Change in Situations.

Rauthmann, Sherman and Funder have made a landmark contribution to situation research in the target article of this issue. However, we propose that their work overlooks the need to incorporate a developmental perspective. This includes the separate but related issues of time and change. Situations often unfold over long periods of time, can bleed together, and are not time-delimited in the way traditional laboratory experiments define them. Moreover, individuals systematically change over time (lifespan development) and their reactions to situations, as well as their personality-situation transactions, develop in tandem.
