MEMORY REFERS TO ENCODING STORAGE AND RETRIEVAL OF INFORMATION MEMORY IS A COGNITIVE OR MENTAL PROCESSES. COGNITION=INTERNAL PROCESSING OF INFORMATION.
3
THREE COGNITIVE PROCESSES OF MEMORY ENCODING PROCESS OF RECEIVING SENSORY INPUT AND TRANSFORMING IT INTO A CODE THAT CAN BE STORED
4
STORAGE IS THE PROCESS OF ACTUALLY PUTTING THE CODED INFORMATION INTO MEMORY.
5
RETRIEVAL IS THE PROCESS OF GAINING ACCES TO THE ENCODED, STORED INFORMATION WHEN IT IS TO BE USED.
6
ATKINSON-SHIFFRIN THEORY BRIEF STORAGE OF INCOMING INFORMATION IN A SENSORY REGISTER TRANSFER OF SOME OF THIS INFORMATION TO SHORT TERM MEMORY(STM). INFORMATIN TRANSFER BY MEANS OF REHEARSAL, FROM STM TO LONG TERM MEMORY(LTM)
7
SENSORY REGISTER STAGE INFORMATION HOLD FOR E FEW SECONDS. HAS RELATIVELY LARGE CAPACITY. STORES A COPY OF THE SENSORY INPUT. LOSES INFORMATION THROUGH A PROCESS INVOLVING THE DECAY OF THE MEMORY TRACE.
8
SHORT TERM MEMORY HOLDS RELATIVELY SMALL AMOUNT OF INFORMATION ABOUT SEVEN ITEM OR CHUNK FOR 30 SECONDS OR SO. SOUNDS, IMAGES, WORDS AND SENTENCES CAN BE STORED. INFORMATION IS LOST BY BEING DISPLACED BY NEW INPUTS. INFORMATION TRANSFER TO LTM THROUGH MAINTENANCE OR ELABORATIVE REHEARSAL.
9
LONG TERM MEMORY INFORMATION IN LTM LASTS FOR DAYS, MONTHS, YEARS OR EVEN A LIFETIME. CAPACITY OF LTM HAS NO LIMIT. SEMANTIC MEMORY ARE STORED IN LTM. INFORMATION LOSE BEACAUSE OF DIFFICULTY WITH THE SEARCH PROCESS OR INTERFERENCE BY OTHER LTMs.
10
LEVEL OF PROCESSING BASED ON DEPTH OF ANALYSIS AND ELABORATION OF INFORMATION: 1/ PERCEPTION: MOST SUPERFICIAL DEPTH. 2/ STRUCTURAL LEVEL: DEEPER LEVEL. 3/ MEANING LEVEL: DEEPEST LEVEL THAT GIVING MEANING TO THE INPUT.
11
LONG TERM MEMORY SEMANTIC MEMORY: KNOWLEDGE OF WORDS MEANINGS AND THE RULES FOR USING LANGUAGE. EPISODIC MEMORY: OUR REMEMBERANCES OF EVENTS.
12
LTM ORGANIZATION FACILITATE ENCODING AND STORAGE(FORMING IMAGES, CONSTRUCTIVE PROCESSE). RETRIEVAL CUES AID RITRIEVING INFORMATION.
13
FORGETTING FORGETTING REFERS TO LOSS OF INFORMATION ALREADY ENCODED AND STORED IN LTM. DEPEND ON: INTERFERENCE DIFFICULTY OF RETIEVAL MOTIVATED FORGETTING
14
AMNESIA AMNESIA IS A PROFOUND MEMORY DEFICIT DUE TO LOSS OF WHAT HAS BEEN STORED OR THE INABILITY TO FORM NEW MEMORIES. AMNESIA MEY BE DUE TO BRAIN MULFUNCTION(ALCOHOL-INDUCED AMNESIA) OR PSYCHOLOGICAL AMNESIA.(DREAM AMNESIA)
15
DEMENTIA DEMENTIA IS A BIOLOGICAL AMNESIA. DUE TO DEGENERATIVE OF MYELINE. ALZHEIMER ’ S DISEASE IS AN EXAMPLE OD DEMENTIA.
