perception
The process by which individuals become aware of, organize, and interpret information received through their senses
Steps in perception
Select available data
organizing data into usable form
interpreting data by adding meaning and making predictions
selection
The conscious effort of choosing which stimulus from all those present in the environment to attend to
We selectively attend to a small amount of available stimuli in any situation
Stimuli we do select may be limited and/or distorted by sensory and psychological factors
influence on selection
intensive stimuli change in stimuli novelty of stimuli our present needs attention limits personal filters
Mental filter
When you pick out a single negative detail and dwell on it exclusively so that your vision of all reality becomes darkened
-David D. Burns,
organization
Discovering the recognizable patterns in the stimulus and recoding them in a form that is simple enough to remember and useIn order to make sense out of our environment it is important for humans to organize and group stimuli into usable patterns.
_________________________________________________________
Typically, the brain automatically initiates the organization perceptual stimuli into patterns
Laws of Organization
closure ,proximity, similarity
closure
incomplete figures tend to be closed or filled into represent a while object
proximity
objects that are closed together tend to be grouped together
similarities
objects that look similar tend to be grouped together
Figure-ground contrast allows figures to be viewed in more than one way
Ambiguous Figures
What your senses tell you is true is not always real
Visual Illusions
Interpretation
The process of attaching meaning to words, acts, or events in our environment and using the meaning to make predictions about future events or behaviors
