Abstract: Comprehensive and accurate measurement of individual differences is important for the optimal development of individuals and societies. With the advancement of psychometric theories and methods, the context-dependence of individual differences is getting increasing attention. More and more researchers have begun to emphasize the quantitative description of individual differences in rich and diverse daily situations and to achieve a more comprehensive and adequate measurement of individual differences than the traditional laboratory measurements through individual performance in multiple situations. Based on the trend and frontier of individual differences research in daily situations, this paper reviews the progress of daily multi-situational individual difference measurement based on subjective reports, behavioral performance, and physiological responses. This paper focuses on the person-center perspective analysis for high-dimensional data in daily multi-situations. The combination of daily multi-situational measurement and profile perspective analysis methods is expected to promote an in-depth understanding of individual difference mechanisms and the deepening and development of individual difference theories.

Key words: Individual differences, everyday situation, dynamics, person-center perspective, physiological profile
