Procrastination is a common human behavior that involves delaying the initiation or completion of important tasks. In spite of its ubiquity, behavioral scientists have paid only modest attention to procrastination, with the result that the behavior has been not been explored in very many contexts. In this essay, the conceptual underpinnings of procrastination are first explored, with special attention paid to the link between procrastination and self-efficacy for self-regulation, particularly in the context of internet use. Next, adolescent procrastination is examined in diverse contexts with a focus on cross-cultural contexts, and on students with special needs. In the final section, treatment for academic procrastination is considered, and avenues for future research are presented.
