The analysis that begins with the sense of receptors and works its way up to the brain's integration portions
Raw interpretation
Bottom-up processing
When we construct images and feelings based on mental conceptions and experiences
When we are told to perceive something
Top-down processing
The minimum stimulation necessary to detect one particular stimulus 50% of the time
Absolute Threshold
Theory predicting how and when we detect the presence that is almost unnoticeable
Signal Detection Theory
Below threshold
Subliminal Stimulation
The minimum amount necessary between two stimuli required for detection 50% of the time
Difference Threshold
The principle that, to be perceived as different, two stimuli must differ by a constant percentage
Weber's Law
Diminished sensitivity as a consequence of a constant stimulation
Sensory Adaptation
One sense may influence another
Sensory Interaction
Mental predisposition to see something else before choosing to see another
Perceptual Set
Perceiving objects that are not really there
Form Perception
Object that we are trying to perceive
Figure
Everything else in our field of vision
Ground
Tending to group objects together in a organized fashion
Grouping
4 types of Grouping
Proximity
Similarity
Continuity
Connectedness
Grouping items that are nearby to each other together
Proximity
Figures of similar shapes we group together
Similarity
We perceive smooth continuous patterns instead of discontinuous ones
Continuity
When linked together we perceive objects and stimuli as one individual unit
Connectedness
Ability to sense depth in an object
Depth Perception
Experiment by Gidson and Walk is an example of
Dpeth Perception
Objects that look farther away than other objects are considered to be more distant
Relative Size
3 Types of Binocular CUes
Retinal Disparity
Convergence
4 types of Monocular Cues
Linear perspective
Texture gradient
Interposition
Relative Size
Keeping your vision on one specific point and watching it pass you by while moving; as the object appear to get closer it is moving faster and as an object moves farther away it moves slower
Relative Motion (Motion Parallax)
When two objects move together by help of two eyes to help create a 3D image
Convergence
Perceiving images as unchanging so that all aspects of the picture remain the same
