We focus our awareness on only a limited aspect of all that we experience. Consciously process about 40 bits out of 11 million.
Cocktail Party effect
Hearing someone at a loud concert next to you. The ability to attend one voice among many. Ex. texting and driving.
When we fail to see changes in the environment.
Ex: Change in pattern on a poster in room.
Background noise effect
Don't realize there's background music in the house and you don't know why you like it besides it being familiar.
the tendency for vision to dominate the other senses
An organized whole; whole picture.
Figure and Ground
the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground).
grouping figures bases on closeness (6 lines as 3 tubes)
grouping figures on similar figures ( u W u )
perceiving smooth, continuous patterns (lines w waves as gumdrops)
objects are seen as connected rather than separate (dots on a line)
we fill in gaps to create a whole image (panda w black legs and white body)
ability to see objects in 3-D although images strike the retina in 2-D. We have depth perception due to our two eyes. Allows us to JUDGE DISTANCE.
lab device that tests depth perception in baby's and animals. Animals come prepared to perceive depth and babies learn over time, through a profess of cues. (Mom telling baby to go over edge)
Depth perception of objects that depend on the use of two eyes. (only right eye open shows different image than when only left eye open)
the difference between the 2 different images created w binocular cues. 3-D movies exaggerate retinal disparity. (extra 3-d)
cues that are available to either eye or alone. Influence our everyday perceptions.
We tend to perceive vertical dimensions as longer than identical horizontal dimensions (We are as tall as our wing span)
further away objects seem smaller
We perceive objects that are higher in our field of vision as farther away.
Parallel lines appear to converge with distance - the more they come together, the greater the perceived distance (rail road tracks seem forever)
Light and Shadow
Dimmer objects are perceived as farther away while brighter objects seem closer
If an object blocks our view of another object, we perceive it as closer
Course distinct texture is perceived as closer than fine, indistinct objects far away appear smaller and more densely packed. (We can see every pine needle on close trees, we see blurry green on far away trees)
Relative Motion (motion parallax)
When in motion, objects that are stable seem to be moving backwards. Objects farther away seem to move slower than the things closer.
We perceive hazy objects are farther away and more clear objects as closer
Light and Shadow
Dimmer objects seem farther away while brighter objects seem closer
We predict that things getting bigger are coming toward us, and visa versa. We are easily tricked by perceptual allusions however.
when lights blink really fast so they looks like it is moving.
even when something is totally the same, because of the context ( shape size brightness ) around it we are able to perceive such objects.
angles and views change our perception of an object. Same sized lines on a parallel railroad tracks.
Perceived lightness depends on the amount of light an object reflects relative to its surrounding
Perceiving objects that are familiar to have consistent color, even if changing illumination alters the wavelengths reflected by the object.
W/ vision we're able to adjust to an artificially displaced or even inverted visual field. Ex: upside down or 30 degree glasses.
Perceptual Set - Schemas
How we perceive one thing, and not the other, based on our assumptions, experiences and expectations (Top-down processing). How we organize unfamiliar objects or information.
We perceive things based on the context. Ex: listening to music and hearing the word "Mourning", happy music would be "morning" sad music would be "mourning"
Human Factors Psychologists
A field dedicated to helping design appliances, work settings and machines fit into our normal perceptions. Ex: person wondering why stoves don't have their buttons like the stove top figure
Extrasensory Perception (ESP)
The controversial claim that perceptions can occur apart from sensory input
Those who study the paranormal - 96% of scientists are skeptical.
mind to mind communication
perceiving remote events Ex: i think my homies' burnt
perceiving future events
mind over matter - being able to move or change physical things w our mind.
