1. Psychology & Human Behavior
âA great design is a blend of pixels, meaning & emotionsâ
Presented By I Nishant Singh - Usability Professional TCS
2. WHAT ARE WE GOING
TO LEARN
†Why Psychology/Human Behaviour in UX?
†Activity 1: Principles of Psychology
†Other Psychological Methods to apply in UX
†Areas of Human Behaviour
†Emotional Advantage
†Psychology behind CTAs
†How to approach a Good Design
†Resources to Learn
†Activity 2: Improve a product (Base your solutions
on psychology)
3. WHY PSYCHOLOGY &
BEHAVIOUR IN
USER HUMANEXPERIENCES
Why donât the user get it?
or
Why does the user like this?
or
Why some designs work and others donât?
4. RE-DESIGN IS A
SERIOUS LOSS
TIME - MONEY - RESOURCES
DO WE REALLY WANT TO BUILD SOMETHING THAT
DOESNâT WORK?
OR
SOMETHING THAT PEOPLE HATE?
10. 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
âGIVE YOUR USERS SOMETHING BEFORE YOU
ASK FOR ANYTHING IN RETURN.â

20. 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 âDecision Making Processâ
†Shopping Experiences(window shopping, YouTube views, LinkedIn endorsements, movie reviews)
†My Shoes - A result of influenced behaviour
âMAKE YOUR USERS BELIEVE THAT YOUR
PRODUCT IS WORTH BUYINGâ
21.
22. PRINCIPLE OF LIKING
†Canât resist the feeling and ultimately saying âyesâ
†E.g. - âearning credits/cash backs/coinsâ - 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?
âMAKE PEOPLE BUILD YOUR
BUSINESSâ

26. PRINCIPLE OF AUTHORITY
†Being confident with CTAs
†Commanding tone instead of asking
âCOMMANDS ALWAYS WORK,
ASKING DOESNâTâ
27.
28.
29. 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
âSCARCITY, USED IN MODERATION AND WITH TRUE INFORMATION,
CAN ENCOURAGE USERS TO MOVE MORE SWIFTLY TOWARDS
CONVERTING ON OUR SITEâ
32. 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

39. 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
âDONâT CONFUSE YOUR USERS. HELP THEM PROCEED TOWARDS
THEIR GOALS & ALWAYS ASK IN CHUNKSâ

43. FITTâS LAW
†Descriptive model of human movement primarily used in humanâcomputer interaction.
†âThis 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.â
†ID - Index of Difficulty, D - Distance & W - Width
†CTAs for touch based devices
44. 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 :)
âIF YOU WANT SOMEONE TO DO SOMETHING, SHOW
SOMEONE ELSE DOING ITâ
45.

47. 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
âMOTIVATE, EXCITE AND LET USER HAVE THE PLEASURE
OF USING YOUR PRODUCTâ
48. 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
49. EMOTIONAL ADVANTAGE
†Frustration
†Rush
†Age Groups/Generations

†Genuineness
†Change Blindness
†Distraction
†Extra Effort

†Recall/Relearn
