...that is not entirely understood. Hence, the relevant conceptual, theoretical, and empirical work is reviewed, drawing upon correlational, experimental, and qualitative findings. A meta-analysis of procrastination’s possible causes and effects, based on 691 correlations, reveals that neuroticism, rebelliousness, and sensation seeking show only a weak connection. Strong and consistent predictors of procrastination were task aversiveness, task delay, selfefficacy, and impulsiveness, as well as conscientiousness and its facets of self-control, distractibility, organization, and achievement motivation. These effects prove consistent with temporal motivation theory, an integrative hybrid of expectancy theory and hyperbolic discounting. Continued research into procrastination should not be delayed, especially because its prevalence appears to be growing. Keywords: procrastination, irrational delay, pathological decision making, meta-analysis Procrastination is extremely prevalent. Although virtually all of us have at least dallied with dallying, some have made it a way of life. Estimates indicate that 80%–95% of college students engage in procrastination (Ellis & Knaus, 1977; O’Brien, 2002), approximately 75% consider themselves procrastinators (Potts, 1987), and almost 50% procrastinate consistently and problematically (Day, Mensink, & O’Sullivan, 2000; Haycock, 1993; Micek, 1982; Onwuegbuzie, 2000a; Solomon & Rothblum, 1984). The absolute amount of procrastination is considerable,...

...MORE ADVANCE NOISE FOR QUIET “An intriguing and potentially lifealtering examination of the human psyche that is sure to benefit both introverts and extroverts alike.” —Kirkus Reviews (starred review) “Gentle is powerful … Solitude is socially productive … These important counterintuitive ideas are among the many reasons to take Quiet to a quiet corner and absorb its brilliant, thought-provoking message.” —ROSABETH MOSS KANTER, professor at Harvard Business School, author of Confidence and SuperCorp “An informative, well-researched book on the power of quietness and the 3/929 virtues of having a rich inner life. It dispels the myth that you have to be extroverted to be happy and successful.” —JUDITH ORLOFF, M.D., author of Emotional Freedom “In this engaging and beautifully written book, Susan Cain makes a powerful case for the wisdom of introspection. She also warns us ably about the downside to our culture’s noisiness, including all that it risks drowning out. Above the din, Susan’s own voice remains a compelling presence—thoughtful, generous, calm, and eloquent. Quiet deserves a very large readership.” —CHRISTOPHER LANE, author of Shyness: How Normal Behavior Became a Sickness 4/929 “Susan Cain’s quest to understand introversion, a beautifully wrought journey from the lab bench to the motivational speaker’s hall, offers convincing evidence for valuing substance over style, steak over sizzle, and qualities that are, in America, often derided. This book is brilliant...
