Unit 2 Flashcards
sensation
detaching, converting and transmitting raw sensory info from the environment
perception
selecting, organizing and interpreting sensory info
top down processing
higher level mental process, conduct perceptions on our experiments and expectations
bottom up processing
analysis that begins with sensory receptors
schema
collection of basic knowledge about a concept that serves as a guide to perception, interpretation and imaginations
perceptual set
mental predisposition (schema) influence how we perceive sensory info
selective attention
the ability to focus on a particular object or activity while ignoring competing stimuli
divided attention
the ability to focus on multiple tasks
- multitasking
- complex executive function
cocktail party effect
ability to focus on one voice with a mix of conversations and background noise
gestalt
process of interpreting and organizing visual info
- take different perceptions to make a whole (filling in holes)
- top down processing
law of prognanz
people will interpret ambiguous or complex images in the simplest form
closure
the tendency to fill in gaps in figures and to see incomplete figures as complete
Ex: dnt wry abt it
proximity
tendency to perceive objects that are close to one another as being grouped together in a meaningful way
similarity
elements that are similar are perceived to be more related than elements that are not similar
continuity
tendency to perceive each of two or more objects as a different, singular and uninterrupted even when intersect
- lines are the smoothest path
connectedness
elements that are connected by uniform visual properties are perceived as connected
figure group
in most visual scenes, we pick out objects that stand out against their surroundings
depth perception
the ability to perceive the relative distance of objects in the visual field
binocular cues
images captured by both eyes to create an image
- retinal disparity
- convergence
retinal disparity
the slight different between the images projected onto each retina
Ex: closing and opening each eye the objects move slightly
convergence
cues that rely on the way your eye muscles work
accommodation
cues that came from muscles attached to the lens
monocular depth cues
depth cues that can be determined with one eye
interposition
distance determined based on the fact that objects overlaps or partially covers another
relative clarity
objects that appear sharper and more clear are closer than hazy objects
relative size
closer object appear larger than distant objects
texture gradient
smaller objects are more thickly clustered appearing further than objects spread out in space
linear perspective
two parallel lines converge, we perceive that vanishing point being further away
brightness constancy
tendency to perceive an objects brightness as the same under different lighting conditions
color constancy
perceive a familiar object as having the same color under different lights
perceptual adaptations
a temporary change in how a person sees or perceives something after being exposed to a new/intense stimuli
apparent movement
perception of movement created by rapidly displaying still images
Ex: flip book
- stroboscopic movement
stroboscopic movement
we perceive movement
Ex: flip book of picture to create the perception of movement
cognition
mental activities associated with thinking, knowing, remembering and communicating
metacognition
thinking about how you think
- evaluating your mental process
- plan, reflect, adjust
concept
mental grouping of similar ideas, objects, events or people
prototype
most typical member in a conceptual category
- stereotype or first thing you think of when given a category
schema
cluster of related concepts; mental frameworks that help us organize and interpret data
assimilation
interpreting new experiences in terms of our existing schema
accommodation
adjusting our schemas to incorporate info provided by new experiences
divergent thinking
coming up with as many possible situations
