Human development approaches to time perspective that are life-span and include multiple developmental periods are largely lacking in the literature even though the topic has received wide attention from many scholars. Extant studies have focused on specific age groups or have compared younger and older adults. This introduction addresses these issues and provides on overview of the multidimensional, developmental, and modifiable qualities of time perspective. The four contributions focus on distinct age groups including adolescents, young adults, middle-aged adults, and older adults. The papers included several conceptualizations of time perspective, diverse participants, and age-specific outcomes. Collectively, this work sets the stage for the next era of age-related research on time perspective.
