The topic of time has long been of interest to psychologists. To date, thousands of studies have, in some fashion or another, addressed temporal issues such as how people perceive and experience time, which temporal domain people emphasize, and whether people will discount the value of future outcomes or delay gratification. In fact, we know a good deal about these basic temporal issues. What we need to better understand is the extent to which such temporal processes impact behavior across a wide range of settings. In this book, we took a domain-driven approach to this question by identifying broad categories of behavior that past theory and research have suggested involve temporal concerns. The contributors to this book have clearly demonstrated the many different domains in which time plays a role in behavior. The range of perspectives and applications our authors have highlighted suggest that the future is bright for research aimed at understanding behavior in the context of time. In this final chapter, we outline several directions for future research based on the chapters in this book.
