The Science of Procrastination
Transcript of The Science of Procrastination
Timothy Pychyl of Carleton University clarifies "all procrastination is delay, but not all delay is procrastination."
In other words, procrastination is irrational delay.
Example: Not doing dishes during finals week. What I will cover today: What is Procrastination?
A short history of procrastination
The causes of procrastination
The underlying neuroscience
References Vincent T. Foss once said, “One of the greatest labor-saving inventions of today is tomorrow.” A short history of procrastination
For most of human existence, resources were scarce and unpredictable
Conservation of energy was crucial for survival.
Immediate needs, immediate results A short history of procrastination Many Centuries Ago Facts about Procrastination 95 percent of students procrastinate at least occasionally (Ellis and Knaus 1977) and close to 50 percent do so with some consistently (Solomon and Rothblum 1984).
Dr. Ferrari (DePaul University) identifies three basic types of procrastinators:
Arousal types, or thrill-seekers, who wait to the last minute for the euphoric rush.
Avoiders, who may be avoiding fear of failure/success. They would rather have others think they lack effort than ability.
Decisional procrastinators, who experience decision paralysis. Bryce Johnson Procrastination Why do we Procrastinate? Hyperbolic discounting: Present has greater value
Task Aversion: Pleasant in Present
Fear of Failure The McCrea Experiment The Neuroscience Behind Procrastination The Mesolimbic Pathway is key to motivation Neuroscience, Continued Our Early Ancestors Sources: Dr. Bill Knaus, Ed.D, Nando Pelusi, Ph.D., Frank Partnoy Sources: Dr. Bill Knaus, Ed.D, Nando Pelusi, Ph.D., Frank Partnoy The Greeks and Romans generally valued procrastination.
Jesus taught that reconciling with our adversaries should be done immediately (Matthew 5:23-24)
Procrastination is a good thing for French:
Under the absolute monarchy of Louis XIV and his successors, nobility became a leisure class, demonstrated by courtly manners and consumption.
In the 1800s and 1900s, French Marxists, Romantics, and Anarchists publicly denounced the discipline of the industrial revolution. The aristocratic disdain for work became the radical's hostility to economic exploitation.

Two different questionnaires were sent to two groups of students and they were asked to respond by e-mail within three weeks. Students would be paid upon completion
One questionnaire had very basic questions: "How do you open a bank account?"
The other questionnaire had very abstract questions: "What type of person opens a bank account?"
Those who thought about the questions abstractly were much more likely to procrastinate and some didn't complete the assignment
Those who answered basic, mundane questions e-mailed their responses much sooner.
Conclusion: Concrete tasks reduce procrastination Areas affected:
ventral tegmental area of the midbrain
Target: Frontal cortex
Neurotransmitters like glutamate and GABA also moderate the action of the pathway, but its primary functions are affected by neurons that respond to dopamine.
In rodents, destruction of the mesolimbic circuit results in loss of cravings, motivation, and lethargy. Limitations:
Just as Dr. Hedges said, the brain is multi-variable, interconnected, and complex
There is even controversy over the Mesolimbic pathway function, especially in learning
Rats with damaged system did not lose ability to learn

Challenge Yourself. Take the long-term perspective. you CAN do it!
Write out your goals daily. (get my physics hw done)
Don't keep it to yourself. Make a public commitment to complete a task.
