PARALLEL PROCESSING
|
THE PROCESS OF SEVERAL ASPECTS OF A PROBLEM SIMULTANEOSLY; THE BRAIN'S NATURAL MODE OF INFO PROCESSING FOR MANY FUNCTIONS INCLUDING VISION
EX:the brain divides and conquers what it sees. It breaks up a scene into four components: color, motion, form, and depth. These are individually analysed and then compared to stored memories, which helps the brain identify what you are viewing. The brain then combines all of these into one image that you see and comprehend |
|
|
DIFFERENCE THRESHOLD
|
THE MINIMUM DIFFERENCE BETWEEN 2 STIMULI REQUIRED FOR DETECTION 50% OF THE TIME; JUST NOTICEABLE DIFFERENCE
EX: ADDING SAND TO YOUR HANDS |
|
|
SUBLIMINAL MESSAGES
|
BELOW ONE'S ABSOLUTE THRESHOLD FOR CONSCIOUS AWARENESS
EX: AS IN ADVERTISING |
|
|
WEBER'S LAW
|
2 STIMULI MUST DIFFER BY A CONSTANT MINIMUM PERCENTAGE INSTEAD OF CONSTANT AMOUNT
|
|
|
SENSORY ADAPTATION
|
DIMINISHED SENSITIVITY AS A CONSEQUENCE OF CONSTANT STIMULATION
EX: GETTING USE TO THE SMELL OF SMOKE AFTER SMELLING IT FOR 30 MINUTES OR SO |
|
|
OPPONENT PROCESS THEORY
|
where emotional reactions to a stimulus are followed by opposite emotional reactions.
EX:may explain why stunt people enjoy their work. First the individual will feel intense anxiety before performing a stunt and then the person will receive an opposite reaction of relief after the stunt is completed. |
|
|
BOTTOM UP PROCESSING
|
ANALYSIS THAT BEGINS WITH THE SENSE RECEPTORS AND WORKS UP TO THE BRAIN'S INTEGRATION OF SENSORY INFORMATOIN
|
|
|
TOP DOWN PROCESSING
|
INFO PROCESSING GUIDED BY HIGHER-LEVEL MENTAL PROCESSES, AS WHEN WE CONSTRUCT PERCEPTIONS DRAWING ON OUR OWN EXPERIENCES AND EXPECTATIONS
|
|
|
SELECTIVE ATTENTION
|
THE FOCUSING OF CONSCIOUS AWARENESS ON A PARTICULAR STIMULUS
EX: WHEN READING A BOOK, YOU CHOOSE TO FOCUS ON THE WORDS INSTEAD OF THE DESK OR THE NOISES AROUND YOU |
|
|
INTERPOSITION
