Perception Flashcards
Perception
The process of organizing and interpreting sensory information
Selective Attention
focus of conscious
awareness on a
particular stimulus.
Perceptual visual capture
tendency for vision to dominate the other senses
Perceptual organization
Gestalt
Gestalt
An organized whole
tendency to integrate pieces of –
information into meaningful wholes
Grouping
The perceptual tendency to organize stimuli into coherent groups
proximity
group nearby figures together
Similarity
group figures that are similar
Continuity
perceive continuous patterns
Closure
fill in gaps
connectedness
spots, lines, and areas are seen as unit when connected
Figure and Ground
organization of the visual field into objects (figures) that stand out from their surroundings (ground)
Depth Perception
ability to see objects in three dimensions
allows us to judge distance
Binocular cues
Retinal disparity and convergence
Retinal Disparity
images from the two eyes differ
closer the object, the larger the disparity
Convergence
two eyes move inward for near objects
Visual Cliff Experiment
(Eleanor Gibson) If you are old enough to crawl, you are old enough to see depth perception
Monocular cues types
-relative size, clarity, height and motion
-interposition
-linear perspective
Relative size
smaller image is more distant
interposition
closer objects block distant objects
Relative clarity
Hazy objects seen as more distant
Relative height
higher objects seen as more distant
Relative motion
closer objects seem to move faster
Linear perspective
parallel lines converge with distance
Monocular cues
You only need one eye
perceptual constancy
perceiving objects as unchanging even as illumination and retinal image change
Perceptual Adaptation
(vision) ability to adjust to an artificially displaced visual field
prism glasses
Perceptual Set
a mental predisposition to perceive one thing and not another
How does our sense of smell work with our sense of taste?
Extrasensory Perception
controversial claim that perception can occur apart from sensory input
ex. Telepathy, clairvoyance etc
Parapsychology
the study of paranormal phenomena
Ex. ESP and psychokinesis
