SENSORY MEMORY Flashcards
FIRST STAGE OF MEMORY
SENSORY MEMORY
THE POINT AT WHICH INFORMATION ENTERS THE NERVOUS SYSTEM THROUGH THE SENSORY SYSTEMS
SENSORY MEMORY
EYES, EARS, NOSE, SKIN, TOUNGE
SENSORY SYSTEMS
INFORMATION IS ENCODED INTO _ MEMORY AS NEURAL MESSAGES IN THE NERVOUS SYSTEM
SENSORY MEMORY
AS LONG AS THE INFORMATION FROM THE NERVOUS SYSTEM THAT TURN INTO NEURAL MESSAGES ARE TRAVELLING THROUGH THE SYSTEM, IT CAN BE SAID THAT PEOPLE HAVE A _ FOR THAT INFORMATION THAT CAN BE ACCESSED IF NEEDED
MEMORY
- ICONIC SENSORY MEMORY
- ECHOIC SENSORY MEMORY
2 KINDS OF SENSORY MEMORY
ICONIC
VISUAL
ECHOIC
AUDITORY
VISUAL SENSORY MEMORY AND LAST FOR A FRACTION OF A SECOND
ICONIC SENSORY MEMORY
GREEK WORD FOR IMAGE
ICONIC
ICONIC MEMORY WAS STUDIED IN SEVERAL CLASSIC EXPERIMENTS BY?
GEORGE SPERLING
SPERLING FOUND OUT IN HIS STUDIES THAT A PRESENTATION OF A GRID OF LETTERS USING A MACHINE THAT ALLOWED VERY FAST PRESENTATION, HIS SUBJECTS COULD ONLY REMEMBER ABOUT _ OR _ NUMBERS OF THE LETTERS
4 or 5
WHAT IS THE SECOND METHOD SPERLING DEVELOPED AFTER THE FIRST STUDY
PARTIAL REPORT METHOD
IN THIS METHOD SPERLING SHOWED A GRID OF LETTER SIMILAR TO THE FIRST ONE BUT IMMEDIATELY SOUNDED A HIGH,MEDIUM OR LOW TONE JUST AFTER THE GRID WAS SHOWN, HE FOUND OUT THAT SUBJECTS COULD ACCURATELY REPORT ANY OF THE THREE ROWS
PARTIAL REPORT METHOD (CAPACITY OF ICONIC MEMORY)
MEANT THAT THE ENTIRE GRID WAS IN ICONIC MEMORY AVAILABLE TO THE SUBJECTS
RESULT OF PARTIAL REPORT METHOD (CAPACITY OF ICONIC MEMORY)
THE CAPACITY OF _ MEMORY IS EVERYTHING THAT CAN BE SEEN AT ONE TIME
CAPACITY OF ICONIC MEMORY
SPERLING FOUND THAT IF HE DELAYED THE TONE FOR A BRIEF PERIOD OF TIME, AFTER SECOND SUBJECTS COULD NO LONGER RECALL LETTERS FROM THE GRID ANY BETTER THAN THEY HAD DURING THE WHOLE REPORT SCHEDULE
DURATION OF ICONIC MEMORY
THE ICONIC INFORMATION HAD COMPLETELY FADED OUT OF SENSORY MEMORY IN THAT BRIEF TIME (DELAYED TO THE TONE)
DURATION OF ICONIC MEMORY
A PROCESS IN WHICH THE INFORMATION THAT JUST ENTERED ICONIC MEMORY WILL BE PUSHED OUT QUICKLY BY NEW INFORMATION
MASKING (COWAN, 1988)
RESEARCH SUGGEST THAT AFTER ONLY A QUARTER OF A _, OLD INFORMATION IS REPLACE BY NEW INFORMATION
QUARTER OF A SECOND
ALSO KNOWS AS PHOTOGRAPHIC MEMORY
EIDETIC IMAGERY
THE RARE ABILITY TO ACCESS A VISUAL MEMORY OVER A LONG PERIOD OF TIME
EIDETIC IMAGERY
HAVING A VERY GOOD MEMORY AND HAVING _ IMAGERY ARE TWO DIFFERENT THINGS
EIDETIC IMAGERY
SOME CLAIMING THAT THEY HAVE A PHOTOGRAPHIC MEMORY ACTUALLY MEAN THAT THEY HAVE AN EXTREMELY _
EXTREMELY GOOD MEMORY
_ MEMORY HELPS THE VISUAL SYSTEM TO VIEW SURROUNDINGS AS CONTINUOUS AND STABLE IN SPITE OF THESE SACCADIC MOVEMENTS
ICONIC MEMORY
the quick movement of the eyes by which the gaze is transferred from one fixation point to another
SACCADIC MOVEMENTS
_ MEMORY ALLOWS ENOUGH TIME FOR THE BRAIN STEM TO DECIDE IF THE INFORMATION IS IMPORTANT ENOUGH TO BE BROUGHT INTO CONSCIOUSNESS
ICONIC MEMORY
THE BRIEF MEMORY OF SOMETHING A PERSON HAS HEARD
ECHOIC SENSORY MEMORY
LIMITED TO WHAT CAN BE HEARD AT ANY ONE MOMENT AND SMALLER THAN THE CAPACITY OF ICONIC MEMORY
CAPACITY OF ECHOIC SENSORY MEMORY
LAST LONGER THAN THE CAPACITY OF ICONIC MEMORY FOR ABOUT 2 -4 SECONDS
CAPACITY OF ECHOIC SENSORY MEMORY
_ MEMORY IS VERY USEFUL WHEN A PERSON WANTS TO HAVE MEANINGFUL CONVERSATIONS WITH OTHERS
ECHOIC MEMORY
_ MEMORY ALLOWS THE PERSON TO REMEMBER WHAT SOMEONE SAID JUST LONG ENOUGH FOR THE LOWER BRAIN CENTERS TO DETERMINE WHETHER OR NOT PROCESSING BY HIGHER BRAIN CENTERS IS NEEDED
ECHOIC MEMORY
