Cognition & Perception Flashcards
Human cognition is often thought of in terms of…?
Computational Analogies
What is ‘Proprioception’?
Sense of knowing where your body is
While focused on the YouTube video, the student reaches out for the coffee cup. Successfully picking up the cup depends on…?
a. Peripheral vision and proprioception
b. Binaural cues
c. Foveal vision and stereo cues
a. Peripheral vision and proprioception
What are the five senses?
- Sight
- Sound
- Smell
- Touch
- Taste
Exteroception
Sensing the outside • Sight • Sound • Smell • Touch • Taste
Interoception
Sensing the inside
• Headaches
• Hunger
• Proprioception (self-movement/body position)
What is the most used sense in interfaces?
sight. Around half the brain is dedicated to vision.
What is the blind spot caused by?
A bundle of nerves connecting to the retina.
Peripheral vision is less clear because…?
You have less cones at the edges of your retina
You are very sensitive to movement at the edge of your vision at night because…?
The cells at the edge are relatively more active in low light conditions.
Fovea
- Centre of vision
- Mainly cones
- Pretty small => need saccades
Peripheral vision
- mainly rods
- detect movement => catch attention
- Catches things that move
Approximately how much of the human brain is dedicated to vision?
50%
How do sounds vary?
- Pitch (frequency)
- Volume
- Timbre… the ‘shape’
- Violin vs. big bass drum
Sound is often used in user interfaces to…?
Attract the user’s attention and provide important feedback following an action or event.
