1. Perceptual organization
- ANS - depth, form, motion, constantly
2. binocular cues
- ANS - depth
3. retinal disparity
- ANS - eyes are 2.5 inches apart
4. convergence
- ANS - depth based on how much eyes are turned, far away eyes
are relaxed, close up eyes contract
5. monocular cues
- ANS - form of object, relative size, interpositoin (overlap), relative
height, shading and contour
,6. motion parallax
- ANS - relative motion, things farther move slower, things closer
move faster
7. constancy
- ANS - perception of object doesnt change despite image on retina
changing, we are smarter, size/shape/color constancy
8. size constancy
- ANS - if object is closer we dont perceive it as bigger just because
its close, we know its the same size
9. sensory adaptation
- ANS - inner ear muscle (higher noise contract, to dampen
vibration in inner ear, protect ear drum)
10. sight: down regulation of light adaptation, when bright
constrict pupils and desensitize rods and cones, or up regulatoin,
when dark dilate pupils and rods and cones synthesize light
sensitive molecules
11. Weber's law
- ANS - JND= just noticeable difference
- threshold at which youre able to notice any change in
sensation
- 2 vs. 2.2 weight is noticeable
12. dI= .1 (noticeable intensity difference)
,13. linear relationship betwen threshold and intensity
14. I vs. dI= linear
15. absolute threshold of sensation
- ANS - differences based on the individual
16. minimum intensity of stimulus needed to detect a particular
stimulus 50% of the time
17. influenced by expectations, experience, motivation, alertness
18. subliminal stimuli
- ANS - stimuli below the absolute threshold of sensation
19. somatosensation
- ANS - intensity, timing, location
20. temp, pressure, pain, position
21. intensity
- ANS - how quickly the neurons fire
22. timing
- ANS - non-adapting= constant firing rate, temp
, 23. slow-adapting= neuron fires in beginning and calms down
after a while, pressure/pain
24. fast-adapting= fires as soon as stimulus starts then stops
firing then starts again when the simulus stops, proprioception,
and some pain
25. vestibular system
- ANS - balance and orientation
26. inner ear= semicircular canals (posterior, lateral, anterior)
27. filled with endolymph to detect motion of the fluid with
rotation
28. otolithic organs= utricle and saccule, detect linear
acceleration and head positioning, calcium carbonate crystals
attached to hair cells in viscous gel, when we move they pull on
hair cells and trigger AP, depend on gravity!
29. dizziness and vertigo
30. Signal Detection Theory
- ANS - how we make decision under conditions of uncertainty,
discern between importnat stimuli and unimportant "noise"
