Situations, environmental niches and people could be measured using the same characteristics

Rauthmann et al. offer a welcome attempt to put situation-sensitive personality research on a firmer conceptual and empirical basis. We suggest a clearer distinction between momentary or current or unique situations and more stable or typical components of situations, and describe a methodology that we are developing that would represent within-individual processes and individual differences as well as interactions between individuals and interactions between individuals and their non-social environments in a single framework. We believe that this can optimally be accomplished by measuring situations and people using the same characteristics. Copyright (C) 2015 European Association of Personality Psychology.
