UX Pschology

Question 1

Perceptual Psychology

Answer 1

• Visibility (principle of proximity, principle of similiarity
• Audio
• Haptics (causal relationship)

Question 2

Information Processing

Answer 2

= This is a cognitive approach which views the mind as a computer.

Input –> perceptual encoding –> translation process –> response selection and execution –> observed response

Distributed Cognition: analysis of cognition should not be limted tot he thinking indivudal, cognition could include mechanism outside the individuals brain

External cognition: how representations can perform computational offloading

Embodied cognition: mind & body, body & physical word are central in shaping our cognition

Question 3

Memory & Learning

Answer 3

Memory: Input –> sensory memory (attention –>) short term memory (rehearsal –>) long term memory
(emotions influence memory)

Magic Number 7: adults can only keep five to nine objects in short-term memory

–> preferring recognition over recall

Learning: intentional and incidental (by product of interaction)

Question 4

Desicion Making

Answer 4

= reflective cognition, which is deliberate thinking resulting in conscious beliefs (effortful, slow)

• -> expected utility hypothesis (weighting pros and cons to maximize ulity of a decision) or heuristics (igonoring some informations)
• -> avoid buyers remorse or analysis paralysis
• -> limit options, make them comparable and categorize them

= Intuitive cognition, immediate

Question 5

Situation Awareness

Answer 5

selective attention = irecting awareness to important stimuli while blocking out unimportant stimuli
The gulf of evaluation and the gulf of execution = describe the gap that can exist between mental and physical states

gulf of evaluation: sytem to user, gap between what the system exhibits and the user’s ability to interpret it.
gulf of execution: user to system, gap between what the system offers and the intention of the user.

Question 6

Errors

Answer 6

Human errors

1. slips (inadvertently performs a wrong action), inattention/memory-loss
2. mistakes (conscious errors that occur when there is a mismatch between a user’s mental model and the reality), misinformation

• -> principle of forgiveness (prevents users from making errors and minimizes the repercussions of the error)
• -> affordance (physical characteristics of an object which hint at correct use)

System errors (Informative messages, how to handle the error, friendly distraction)
