Transcript of The Chemistry of Procrastination

The Chemistry of...
PROCRASTINATION
WHAT IS PROCRASTINATION?
procrastinate (verb) - to put off or defer (an action) until a later time; delay
- procrastination is a mental decision
distractions
preference
laziness
WHAT CAUSES
PROCRASTINATION?

- this (sometimes involuntary) decision occurs in the brain
WORK
- dopamine, a
neurotransmitter,
is directly related to procrastination
WHAT IS DOPAMINE?
- dopamine is a neurotransmitter
- it helps control the brain's pleasure and reward centers
- it enables the brain to realize the presence of rewards
and guides the
decisions needed to
reach them
CHEMICAL MAKE-UP OF DOPAMINE
- the chemical formula of dopamine is C H NO
8

2
- it is a covalent compound
WHAT DOES DOPAMINE DO?
- it is a monoamine
-in the frontal lobe, dopamine regulates motivation and emotional response
-in the nucleus accumbens, dopamine regulates the sense of reward
HOW DOPAMINE REACTS
synapatic cleft
nerve ending

THE MONOAMINE NEUROTRANSMITTER
neurotransmitter - a chemical substance that transports nerve impulses
monoamine neurotransmitter - a neurotransmitter that contains one amine group connected to a hydrocarbon by a two-carbon chain

DOPAMINE RECEPTORS
- once the dopamine reaches the receptors, it can then send signals to the body to act upon the task ahead
DOPAMINE AND PROCRASTINATION:
RECAP
- levels of dopamine have a direct relationship with levels of motivation
- chronic procrastinators have fewer dopamine receptors, so there is less likely that they will be motivated
WHY I CHOSE PROCRASTINATION
- I wanted to do something that no one had probably ever done
- I've had a lot of personal experience with procrastination
- I became interested in the functions in the brain that caused this habit

Period 2
-dopamine is a monoamine neurotransmitter
- reacts with a Calcium ion to reach the receptors
- once at the receptors, the body is signaled to take action
- the lack of dopamine is what causes procrastination
- the lack of dopamine in the brain causes procrastination
