WHY PSYCHOLOGY & BEHAVIOUR IN

USER HUMAN EXPERIENCES

Why don’t the user get it?orWhy does the user like this?orWhy some designs work and others don’t?

RE-DESIGN IS A SERIOUS LOSS

TIME - MONEY - RESOURCESDO WE REALLY WANT TO BUILD SOMETHING THAT

DOESN’T WORK?OR

SOMETHING THAT PEOPLE HATE?

PRINCIPLES THAT AFFECT HUMAN BEHAVIOUR

HOW TO USE THEM AS WEAPONS OF INFLUENCE

ACTIVITY TIME GUESS THE PSYCHOLOGY PRINCIPLE USED IN THE

IMAGES

PRINCIPLE OF RECIPROCITY➤ Sense of obligation➤ Morally bound by the rule to do something➤ Something like a favour/act of kindness/a service➤ More likely to return the favour➤ Increases the probability of making business➤ Nielsen Norman Group(NN/g) - https://www.nngroup.com➤ In case of vice-versa, people are more likely to abandon the site

“GIVE YOUR USERS SOMETHING BEFORE YOU ASK FOR ANYTHING IN RETURN.”

COMMITMENT➤ Promise to provide a value➤ Instills a sense of responsibility➤ Telling users to trust your business➤ Being loyal to the end users➤ Building long term relationships

“PROMISE, DELIVER AND MAKE BUSINESS”

CONSISTENCY➤ Providing value as promised➤ Being specific tells users when to expect what they need➤ Feeling of satisfaction➤ Avoids false expectations at wrong times➤ Meeting the increased expectations➤ Stronger relationship which builds over time

“DELIVER WHAT IS PROMISED AT THE RIGHT TIME”

SOCIAL PROOFING (RATINGS, REVIEWS, TESTIMONIALS & RECOMMENDATIONS)➤ Human behaviour is guided by others behaviour➤ Natural human tendency - to behave correctly - how its gets validated➤ More likely to buy a product➤ Builds trust on the product➤ Influences the “Decision Making Process”➤ Shopping Experiences(window shopping, YouTube views, LinkedIn endorsements, movie

reviews)➤ My Shoes - A result of influenced behaviour

“MAKE YOUR USERS BELIEVE THAT YOUR PRODUCT IS WORTH BUYING”

PRINCIPLE OF LIKING➤ Can’t resist the feeling and ultimately saying “yes”➤ E.g. - “earning credits/cash backs/coins” - many apps use this - receive

credits when others install apps on their references➤ Candy Crush(Principle of reciprocity also acting seamlessly here)➤ CrownIt➤ Why are we here?

“MAKE PEOPLE BUILD YOUR BUSINESS”

PRINCIPLE OF AUTHORITY➤ Being confident with CTAs➤ Commanding tone instead of asking

“COMMANDS ALWAYS WORK, ASKING DOESN’T”

PRINCIPLE OF SCARCITY➤ Causes people to assign high value to things they perceive as being less available➤ Human nature: Putting more subjective value on loss than on the gain➤ Sense of loosing something valuable➤ Things to play with in terms of the scarcity rule

➤ Number of goods➤ Limited Time➤ Making information scarce via newsletters

➤ What is so important that everyone is buying it➤ Sense of high quality➤ E.g. - Black Friday Sale(Day before thanksgiving in US), railway tickets, loosing $100 than gaining

“SCARCITY, USED IN MODERATION AND WITH TRUE INFORMATION, CAN ENCOURAGE USERS TO MOVE MORE SWIFTLY TOWARDS CONVERTING ON OUR SITE”

LET’S HAVE A LOOK AT THEM AGAIN

SOME OTHER METHODS/RULES

TO APPLY

RULE OF THIRDS➤ Aligning a subject with these points

creates more tension, energy and interest in the composition than simply centering the subject

➤ Dull if centered➤ Tension between the object & negative

space➤ More like a guideline than a rule➤ Makes composition more dynamic➤ Contrast in objects

MAGIC NUMBER 7+/-2 ➤ Number of objects an average human mind can hold in working memory is

7+/-2➤ More choices -> Less satisfaction➤ More choices -> More confusion➤ Decreases the efficiency and hence effects decision making➤ Can be implemented where user details are required➤ Filtering out the options

“DON’T CONFUSE YOUR USERS. HELP THEM PROCEED TOWARDS THEIR GOALS & ALWAYS ASK IN CHUNKS”

FITT’S LAW➤ Descriptive model of human movement primarily used in human–computer

interaction.➤ “This scientific law predicts that the time required to rapidly move to a target

area is a function of the ratio between the distance to the target and the width of the target.”

➤ ID - Index of Difficulty, D - Distance & W - Width

➤ CTAs for touch based devices

MIRROR NEURONS➤ Neurons that mirror the behaviour of other as though the observer were

itself acting➤ Instigates copying mechanism➤ Implemented in Learning Mechanisms➤ E.g. - Movies, cookies :)

“IF YOU WANT SOMEONE TO DO SOMETHING, SHOW SOMEONE ELSE DOING IT”

DOPAMINE➤ Body compound➤ Precursor of substances like adrenalin➤ Pleasure seeking chemical➤ Gaming - pleasure people experience and the desire to continue➤ Motivation, mindset, attention & retention➤ Spikes during high stress➤ Eliminate the unnecessary stress not all

“MOTIVATE, EXCITE AND LET USER HAVE THE PLEASURE OF USING YOUR PRODUCT”

AREAS OF HUMAN BEHAVIOUR➤ Abilities and Limitations

➤ Specific user goals➤ Multitasking & Business Goals➤ Least work possible

➤ Patterns➤ Scanning➤ Mistakes - Anticipate, Predict & Prevent - Undo➤ Confirmation through states➤ Inline Validation➤ Modularity - Dividing tasks into chunks - forms➤ Interaction, User Feedback and Testing

➤ Human Cognition/Cognitive Psychology➤ Mental Models (Shapes/Conventions/Past Experiences)➤ Problem Solving and Decision Making➤ Emotion Driven Behaviour

EMOTIONAL ADVANTAGE➤ Frustration➤ Rush➤ Age Groups/Generations➤ Memory & Knowledge➤ Genuineness➤ Change Blindness➤ Distraction➤ Extra Effort➤ Past Experience➤ Recall/Relearn➤ Mistakes - Anticipate, Predict and Prevent - Undo Mistakes

CALLS TO ACTIONS(CTAs)- BUSINESS DRIVER

PSYCHOLOGY BEHIND CTAs & HOW TO IMPLEMENT➤ Gifts (Reciprocity/Scarcity Principle) - To add value➤ Size and Placement (Fitt’s Law and Rule of Thirds)➤ Feedback➤ Progress State➤ Enticing Calls to Actions

1. Double Diamond Design Model - British Design Council - 20052. User Research - Observation & Usability Testing3. Psychology of Color, Type and Shapes (Things that can be taken advantage of)4. Affordances5. Feedback - Beeps/Tones/Clicks6. Stand out(Rule of Thirds) - Visual Perception & Appeal - Eye-tracking studies7. Make things obvious8. Defaults9. Improve CTAs10. Current State11. Confirmation for severe things12. Minimal Design(Avoid Featuritis/Creeping Featurism)13. Dopamine: Grab and hold attention of end-user/human
