Sociology and Psychology Flashcards
What are visual cues? What do they do?
Visual cues are depth, form, motion, constancy. They allow us to perceptually organize. Human cues are binocular because we have two eyes causing the retinal disparity.
What is the relevance of retinal disparity?
Human eyes are 2.5 inches apart causing retinal disparity (different views) giving us a perception of depth.
Binocular vs monocular cues
Binocular cues require two eyes monocular cues require one
Convergence
Binocular cue: gives us an idea of depth based on how much the eyeballs are turned. If the eye muscles are contracted item is close if items are far muscles are relaxed
Relative Size
Monocular cue: the closer an object is the bigger it is perceived.
Interposition
Monocular cue: overlap, idea that if one item is in front of the other it is the closer item
Relative height
Monocular cue: things that are higher are perceived as farther away than things that are lower.
Shading and Contour
Monocular Cue: lights and shadows create depth and contours
Motion Parallax
Monocular Cue: The further things are the slower they move
Constancy
Monocular Cue: Our perception of an object doesn’t change even if the image cast on the retina is different. Different types of constancy include size constancy, shape constancy, color constancy.
Sensory Adaption
Our senses change sensitivity based on stimuli
Hearing Adaption
Inner ear muscle contracts in response to louder noise to dampen sound
Touch Adaption
Temperature receptors desensitize over time
Smell Adaption
Receptors desensitize over time
Proprioception Adaption
Sense of position resets after being altered
