In this systematic review, we present a comprehensive overview of the temporal person environment (PE) fit literature. To this end, we organize and integrate extant temporal fit research and discuss research trends and developments in the temporal domain. Our analysis reveals that temporal conceptualizations of fit vary in terms of change process (transitional, developmental, transformational), level of aggregation (situational vs. baseline level), and temporal frame (clock time vs. psychological time), all of which divide the temporal fit literature in significant ways. Furthermore, our analysis shows that progress in the temporal fit domain has been confined by five major obstacles: An emphasis on selection and socialization processes, a narrow focus on the between-person level of analysis, preoccupation with linear change, a strong interest in normal causation questions, and a lack of attention to misfit. We conclude with a discussion of the research challenges that lie ahead and provide suggestions to tackle these challenges and expand temporal PE fit research in new directions.
