Procrastination is a common self-regulation failure that has been studied mainly in the educational context, but has been largely neglected in life-span psychology. Adopting a life-span motivational perspective, we focus on adult development and maintain that, historically seen, adults nowadays have to take on a more active role in pursuing their goals due to the deregulation of the life course and increased life expectancy. This requires higher self-regulatory skills, particularly with increasing age. When self-regulation fails, people may postpone developmental goals and experience negative consequences. We propose research questions that might foster the understanding of procrastination from a life-span perspective.
