Overview
• “Gamification”• Using game elements in non-game contexts
• Psychological foundations• Punishment and reinforcement
• And when to punish or reinforce
• Examples in highway safety
Gamification
• “Game design elements in non-game contexts” (Deterding, 2011)• Ex: Fitness, Education, Apps
• Make it FUN!!
• Game design elements• Pyramid (Werbach, 2012)
• Game Dynamics
• Game Mechanics
• Game Components
“Grammar”
• Create implicit structure
• Ex: general narrative,
constraints to force
decision-making
“Verbs”
• Drive action forward
• Ex: challenges, chance,
feedback, rewards
“Nouns”
• Instantiations of elements
higher in the pyramid
• Ex: points, badges,
leaderboards
Wait a second…I took Psychology 100 in undergrad and this doesn’t
sound all that special.
Operant Conditioning
• E.L. Thorndike - Law of Effect (1898)• Followed by B.F. Skinner
• Stimulus -> Response -> Outcome• Reinforcement – satisfying outcome that strengthens
association• Increase responding
• Punishment – aversive outcome that weakens association• Decrease responding
• Positive – Added to the environment
• Negative – Removed from the environment

When to Punish or Reinforce
• Immediate• Outcome needs to be associated with response
• Schedule• Interval – amount of time
• Ratio – number of responses
• Fixed – fixed (predictable)
• Variable – varies (unpredictable)
Is reinforcement based on a number of
responses or an amount of time
passed?
Is the number of responses fixed or
does it vary?
Fixed Ratio Schedule
Reinforce after fixed number of responses
Ex: FR3 = reinforce after every three responses
Predictability creates a break-and-
run pattern of responses
Variable Ratio Schedule
Reinforce after variable number of responses
Ex: VR3 = reinforce after 2 responses, then 4, etc.
Unpredictability creates high and steady rate of
responding
Is the amount of time fixed or does
it vary?
Fixed Interval Schedule
Reinforce after fixed amount of time has
passed
Ex: FI3 = reinforce the first response after 3 minutes
Predictability creates a scalloping pattern of responses
Variable Interval Schedule
Reinforce after variable amount of time has
passed
Ex: VI3 = reinforce after 2 minutes, then 4, etc.
Unpredictability creates high and steady rate of
responding

Continuous vs. Partial
• Continuous – every response reinforced
• Partial – some responses reinforced• Longer to build association, but it lasts longer (resistant to
extinction)
• “partial reinforcement effect” – huge motivation• Ex: gambling
Examples in Highway Safety (speeding)
• Accident• Positive punishment
• Add adverse outcome to reduce future responding
• Outcome Broken car/human
• Ticket• Positive punishment
• Add adverse outcome to reduce future responding
• Outcome Loss of money/time
• Cop vs. Camera
Examples in Highway Safety (driving the speed limit)
• Loss avoidance• Negative reinforcement (remove adverse outcome(s) to reduce future
responding)
• Outcome -> No accident or ticket
• Tickets (and avoiding them) are lame.• Make driving the speed limit FUN!!
Speed Camera Lottery

Speed Camera Lottery
• Speed camera• Speeders pay fines into a pot
• Non-speeders entered into a drawing to win the money from the pot
• Lead to 22% decrease in traffic speed
• Positive reinforcement• Add satisfying outcome (money)
• Lottery = partial reinforcement effect• Huge motivation from being reinforced only some of the time
In conclusion
• “Gamification” (or the use basic psychological principles) can be seen in highway safety.
• Make being safe…
FUN!!!
