A) Cognitive Variability

Question 1

what did andermane et al (2019) say about short term memory

Answer 1

individuals that have strong, stable visual short term memory representations and the ability to resist distraction are more successful incorporating unexpected changes into the contents of visual awareness

Question 2

usability and rule complexity (Nielson, 2016) (4)

Answer 2

level 0 - few steps are required and no sub-goal has to be generated
level 1 - only simple forms of reasoning, such as assigning items to categories, no need to contrast or integrate information
level 2 - may require evaluating relevance and discarding distractors. some integration and inferential reasoning may be needed
level 3 - may require evaluating relevance and reliability of information in order to discard distractors. integration and inferential reasoning may be needed to a large extent

Question 3

neurodiversity meaning

Answer 3

the diversity of human brains and minds, the infinite variation in neurocognitive functioning within our species

Question 4

Answer 4

• partial sightedness
  -refractive errors
  -macular degeneration
  -cataracts
  -diabetic retinopathy
  -hemainopia
  -sensory overload

Question 5

two types of colour blindness

Answer 5

• deuteranopia - (deuteranomaly - green) and protanopia (protanomaly - red)
• tritanopia (tritanomaly)

Question 6

usability and colour blindness (4)

Answer 6

• avoid problematic colour combinations
• use high contrast and modulate brightness, saturation and hue
• use thicker lines
• use both colours and symbols

Question 7

parkinsons disease

Answer 7

this slow progressive, neurogenerative disorder causing tremor, stiffness and slowed movement (bradykinesia)

Question 8

fine motor skills in usability

Answer 8

• don’t have short time-out windows
• provide shortcuts
• design for keyboard or speech-only use
• give content and form fields space
• make large clickable actions

Question 9

individual differences in age (3)

Answer 9

• early life - optimal growth and development
• adult life - enduring highest possible level of function
• older age - maintaining highest possible of function/preventing disease
