Unit 3 Sensation And Perception Flashcards
Taking sensory information and then assembling and integrating it
Bottom up processing
What am I seeing
Using models ideas and expectations to interpret sensory information
Top down processing
Is that something I’ve seen before?
Visual
Auditory
Hearing
Taste
Touch
5 senses
Refers to the physical stimulation of the sensory receptors
Sensation
Involves interpreting this sensory information
Perception
Senses driven
Rely on information from senses
Lower level cognition
Organizing info
Bottom up
Schema driven
Rely on knowledge and experiences
High level cognition
Interpreting info
Top down
Light waves strike the eye
Rode and cones in the retina
Visual
Sound waves striking the outer ear
Cochlear hair cells in the inner ear
Hearing
Chemical molecules breathing in through the the nose
Millions of receptors at top of nasal cavity
Smell
Any change in positions of the body part, interaction with visions
Kinesthetic sensors in joints tendons and muscles
Position/ movement of body parts kinesthesis
Movement of fluids in the inner ear caused by head/body movement
Hairlike receptors in the semi circular canals and vestibular sacs
Position/ movement of head vestibular sense
We perceive objects higher in our field of vision as farther away because we perceive the lower part of a figure ground
Relative hight
If we assume two objects are similar in size most people perceive the one that casts the smaller retinal image as farther away
Relative hight
If one object partially blocks our view of another we perceive it as closer
Interpersonal
Parallel lines such as railroad tracks appear to converge in distance the more they converge the greater their perceived distance
Linear perspective
As we move objects that are actually stable may appear to move
Relative motion
An organized whole, these psychologists emphasized our tendency to integrate pieces of information into meaningful wholes
Gestalt
The organization of the visual field into objects that stand out from their surroundings
Figure ground
Th perceptual tendency to organize stimuli into coherent groups
Grouping
We group nearby figures together
Proximity
We group similar figures together
Similarity
We perceive smooth continued patterns rathe than discontinuous ones
Continuity
Because they are uniform and linked, we perceive each set of two dots and the line between them as a single unit
Connectedness
We fill in gaps to create a complete whole object
Closure
The ability to see objects in three dimensions although the images that strike the retina are two dimensional allows us to judge distance
Depth perception
A laboratory device for testing depth perception in infants and young animals used for Eleanor Gibson and Richard walk to determine whether crawling infants could perceive depth
