Law of Behaviour

We really just want two things

More good feelings = rewards
5
Fewer bad feelings = costs
6
Most actions are choices (conscious or not)
Nothing

action choice value =
rewards - costs

Law of Behavioural Choice
• Actions with higher values are chosen
• Values change over time and context
• Immediate rewards and costs dominate
value of action = rewards - costs
11
Costs:
Effort
Pain
Discomfort
Bad emotions
Embarrassment
Rewards:
Recognition
Pleasure
Comfort
Good emotions
Internal rewards and costs
12
To increase a behaviour
• Increase rewards
• Decrease costs

Fogg's behaviour design model
Rewards-Cost
Reducing cost of effort

Designing for needs and motivation
Maslow's Hierarchy
Physiology (hunger, thirst, sleep, etc.)
Safety/Security/Shelter/Health
Belongingness/Love/Friendship
Self-esteem/Recognition/Achievement
Self actualization
15
Self Determination Theory (Deci)
Mastery
Autonomy
Connection

Behavioural Design Considerations
What is the motivational context of my technology?
-Rewards and Costs • Life context• Technology context• Different users (segmentation)• As a function of time

Example: Travel sitePossible Rewards:

User testing very important!

-Clarity and simplicity of user actions
-Incremental steps in behaviour
-Onboarding in game design
Minimize effort
