MEMORY
WHAT IS MEMORY ???
THERE ARE CERTAIN DEFINITIONS OF MEMORY:
1. A PERSON’S POWER OF REMEMBER THINGS.
2. MEMORY IS A LEARNING THAT PERSISTED OVER TIME.
3. MEMORY IS A PROCESS OF ENCODING , STORAGE AND RETRIEVAL OF INFORMATION
TYPES OF MEMORY
• SENSORY MEMORY
• SHORT TERM MEMORY • LONG TERM MEMORY
TYPES OF MEMORY
• SENSORY MEMORY:SENSORY MEMORY IS THE EARLIEST STAGE OF THE MEMORY.SENSORY MEMORY HOLDS THE SENSORY INFORMATION FOR A
VERY BRIEF PERIOD OF TIME.
HALF SECOND FOR VISUAL INFORMATION3 – 4 SECONDS FOR AUDITORY INFORMATION
TYPES OF MEMORY
Iconic Memory Echoic Memory Haptic Memory
Examples:
TYPES OF MEMORY
• SHORT TERM MEMORY:SHORT TERM MEMORY, ALSO KNOWN AS ACTIVE MEMORY, IS THE INFORMATION WE ARE CURRENTLY AWARE OF.
SHORT TERM MEMORY REMAIN FOR 20 – 30 SECONDS.
Sensory Memory Pay Attention Short Term
Memory
TYPES OF MEMORY
• EXAMPLES:
TYPES OF MEMORY
• LONG TERM MEMORY:CONTINUING STORAGE OF INFORMATION.MOSTLY UNAWARE OF LONG TERM MEMORY.LONG TERM MEMORY CALL IS REFERRED AS
PRECONSCIOUS AND UNCONSCIOUS.
TYPES OF MEMORY
Implicit MemoryExplicit Memory
TYPES OF MEMORY
• EXPLICIT MEMORY:THE CONSCIOUS , INTENTIONAL RECOLLECTION OF PREVIOUS
EXPERIENCES AND INFORMATION.ALSO KNOWN AS DECLARATIVE MEMORY.THESE MEMORIES ARE FORMED THROUGH EFFORTFUL PROCESSING.
Episodic MemoriesSpecific life Events
Semantic MemoriesFacts , Words , Concept
TYPES OF MEMORY
• IMPLICIT MEMORY:
PREVIOUS EXPERIENCES AID IN THE PERFORMANCE OF A TASK WITHOUT CONSCIOUS AWARENESS OF THESE PREVIOUS EXPERIENCES.
Procedural MemoriesRide a bike
Conditional MemoriesThe real reason of Pavlov’s dog

INTELLIGENCE
WHAT IS INTELLIGENCE ?INTELLIGENCE IS THE ABILITY TO UNDERSTAND COMPLEX IDEAS, TO ADOPT EFFECTIVELY
TO THE ENVIRONMENT, TO LEARN FROM EXPERIENCE, TO ENGAGE TO VARIOUS FORMS OF REASONING, TO OVERCOME OBSTACLES BY TAKING THOUGHT.
-ACCORDING TO AMERICAN PSYCHOLOGICAL
ASSOCIATION IN 1995.
THEORIES OF INTELLIGENCE
THEORIES OF INTELLIGENCE HOLD THAT INTELLIGENCE CAN BE MEASURED BY INTELLIGENCE TESTS.
BUT SOME RESEARCHERS ARE DISSATISFIED WITH THAT NOTION AND ARGUE THAT INTELLIGENCE TEST IS NOT ENOUGH TO DEFINE INTELLIGENCE
THEORIES OF INTELLIGENCE
1. HOWARD GARDNER’S THEORY OF MULTIPLE INTELLIGENCES
• INTERPERSONAL INTELLIGENCE :- ABILITY TO UNDERSTAND THE FEELINGS AND INTENTIONS OF OTHERS.• INTRAPERSONAL INTELLIGENCE :- ABILITY TO UNDERSTAND ONE’S OWN FEELINGS AND MOTIVATIONS• LINGUISTIC INTELLIGENCE :- ABILITY TO EFFECTIVELY MANIPULATE LANGUAGE TO EXPRESS ONESELF RHETORICALLY OR POETICALLY.
THEORIES OF INTELLIGENCE• LOGICAL-MATHEMATICAL INTELLIGENCE :- ABILITY TO DETECT PATTERNS, REASON PERSUASIVELY AND THINK LOGICALLY.• E. MUSICAL INTELLIGENCE :- CAPACITY TO RECOGNIZE AND COMPOSE MUSICAL PITCHES, TONES AND RHYTHMS.• NATURALIST INTELLIGENCE :- ENABLES HUMAN BEING TO RECOGNIZE, CATEGORIZE AND DRAW UPON CERTAIN FEATURES OF THE ENVIRONMENT.• SPATIAL INTELLIGENCE :- ABILITY TO MANIPULATE AND CREATE MENTAL IMAGES IN ORDER TO SOLVE PROBLEMS• BODILY-KINESTHETIC INTELLIGENCE :- ABILITY TO USE ONE’S MENTAL ABILITIES TO COORDINATE ONE’S OWN BODILY MOVEMENT.
TRIARCHIC THEORY OF INTELLIGENCE
2. TRIARCHIC THEORY OF INTELLIGENCE BY ROBET STERNBERG’S
INTELLIGENCE HAS THREE FUNDAMENTAL ASPECTS, THE ANALYTIC, CREATIVE AND PRACTICAL (GOOD AT PROBLEM SOLVING) HE SUGGESTED THAT THERE MUST BE A BALANCE OF THE THREE MENTIONED ASPECTS.
THURSTONE’S MULTIFACTOR THEORY
3. THURSTONE’S MULTIFACTOR THEORY
THIS THEORY WAS FORMULATED BY AN AMERICAN PSYCHOLOGIST LOUIS L. THURTONE. HE STRESSED THAT INDIVIDUAL HAVE AT LEAST SEVEN PRIMARY MENTAL ABILITIES NAMELY: VERBAL ABILITY, NUMBER, SPATIAL, MEMORY, REASONING AND WORD FLUENCY.
MEASUREMENT AND EVALUATION OF INTELLIGENCE
• ONE OF THE MOST WIDELY USED INSTRUMENTS TO MEASURE AND EVALUATE INTELLIGENCE IS BY MEANS OF INTELLIGENCE TEST.
• STANFORD-BINET INTELLIGENCE SCALE (SBIS) :-THIS TEST WAS ORIGINALLY DESIGNED TO MEASURE THE MENTAL ABILITIES OF SCHOOL CHILDREN.
MEASUREMENT AND EVALUATION OF INTELLIGENCE
THE FORMULA FOR INTELLIGENCE QUOTIENT IS
WHEREAS :
IQ = INTELLIGENCE QUOTIENT
MA = MENTAL AGE
CA = CHRONOLOGICAL OR ACTUAL AGE
FORMULA IQ=MA/CA X 100
STANFORD - BINET CLASSIFICATION OF INTELLIGENCE
140 ABOVE--------------------VERY SUPERIOR120-140-----------------------SUPERIOR110-120-----------------------HIGH AVERAGE90 – 110-----------------------NORMAL OR AVERAGE80-90 ---------------------------BELOW AVERAGE70-80 ---------------------------BORDERLINE50-70 ---------------------------MORON25-50 ---------------------------IMBECILE25 BELOW----------------------IDIOT
WECHSLER ADULT INTELLIGENCE SCALE (WAIS)
THIS TEST WAS DESIGNED TO MEASURE THE GENERAL INTELLIGENCE OF ADULT.
WECHSLER CLASSIFICATION OF INTELLIGENCE128 AND OVER--------------VERY SUPERIOR120-127---------------------SUPERIOR111-119---------------------BRIGHT NORMAL91-110-----------------------AVERAGE80-90-------------------------DULL NORMAL66-79-------------------------BORDERLINE65 AND BELOW---------------DEFECTIVE
MENTALLY RETARDEDACCORDING TO THE DIAGNOSTIC AND STATISTICAL MANUAL OF MENTAL DISORDERS( DSM-IV),THE CHARACTERISTICS OF A MENTALLY RETARDED ARE AS FOLLOWS:
BELOW 70 IQ DIFFICULTY IN PERFORMING ADAPTIVE BEHAVIOR DIFFICULTY IN PERFORMING ADAPTIVE BEHAVIOR BECAME
APPARENT BEFORE THE AGE OF 18
ADAPTIVE BEHAVIOR REFERS TO THE SKILLS NEEDED TO IVE INDEPENDENTLY THAT ARE
MINIMALLY ACCEPTABLE LEVEL FOR ONE’S AGE.
THREE LEVELS OF MENTALLY RETARDED
• MORON :- EDUCABLE MENTALLY RETARDED WITH A MENTAL AGE OF 12 YEARS AND AN IQ LEVEL OF 50-70• IMBECILE :- TRAINABLE MENTALLY RETARDED WITH A MENTAL AGE OF 7 YEARS AND AN IQ LEVEL OF 25-50• IDIOT :- CUSTODIAL MENTALLY RETARDED WITH A MENTAL AGE OF 3 YEAR OLD AND AN IQ LEVEL OF BELOW 25
THE MENTALLY GIFTED• IN 1972, MARLAD DESCRIBES GIFTED STUDENTS AS THOSE
WHO GIVE EVIDENCE OF HIGH ACHIEVEMENT CAPABILITY IN AREAS SUCH AS INTELLECTUAL, CREATIVE, ARTISTIC OR LEADERSHIP CAPACITY, OR IN SPECIFIC ACADEMIC FIELDS.
• SPECIFICALLY, THE CHARACTERISTICS OF MENTALLY GIFTED ARE AS FOLLOWS
1. 130 IQ AND ABOVE;2. USUALLY TALENTED OR GIFTED; AND,3. ACADEMICALLY SUPERIOR
Computer based Intellegence?
THE HISTORY OF AI
AFTER WWII, A NUMBER OF PEOPLE INDEPENDENTLY STARTED TO WORK ON INTELLIGENT MACHINES. THE ENGLISH MATHEMATICIAN ALAN TURING MAY HAVE BEEN THE FIRST. HE GAVE A LECTURE ON IT IN 1947. HE ALSO MAY HAVE BEEN THE FIRST TO DECIDE THAT AI WAS BEST RESEARCHED BY PROGRAMMING COMPUTERS RATHER THAN BY BUILDING MACHINES. BY THE LATE 1950S, THERE WERE MANY RESEARCHERS ON AI, AND MOST OF THEM WERE BASING THEIR WORK ON PROGRAMMING COMPUTERS.
IN THE NEWS
‘EUGENE’ BECOMES FIRST COMPUTER TO PASS THE TURING TEST ' - THESTAR.COM
THAT COMPUTER ACTUALLY GOT AN F ON THE TURING TEST – WIRED.COM IBM'S WATSON STARTED TALKING LIKE HUMANS AFTER LEARNING THE URBAN
DICTIONARY - HTTP://WWW.IBTIMES.COM
ARTIFICIAL INTELLIGENCE:• ARTIFICIAL INTELLIGENCE (AI) IS THE INTELLIGENCE OF
MACHINES AND ROBOTS AND THE BRANCH OF COMPUTER SCIENCE THAT AIMS TO CREATE IT• THE ABILITY TO SOLVE PROBLEM• THE ABILITY TO ACT LIKE HUMANS
•HOW COMPLICATED IS OUR BRAIN?• NEURON• 10 12 NEURONS IN A HUMAN BRAIN• MANY MORE SYNAPSES (10 14) CONNECTING THESE NEURONS• CYCLE TIME: 10 -3 SECONDS (1 MILLISECOND)
•HOW COMPLEX CAN WE MAKE COMPUTERS?• 108 OR MORE TRANSISTORS PER CPU • SUPERCOMPUTER: HUNDREDS OF CPUS, 1012 BITS OF RAM • CYCLE TIMES: ORDER OF 10 - 9 SECONDS
•CONCLUSIONYES• LESS INTERCONNECTIONS (WIRES OR SYNAPSES) • FASTER
APPLICATIONS OF AI:•NATURAL LANGUAGE UNDERSTANDING
AND SPEECH RECOGNITION•COMPUTER VISION• INTELLIGENT ROBOT•EXPERT SYSTEMS•PERSONAL ASSISTANTS
NATURAL LANGUAGE PROCESSING• TO DESIGN AND BUILD SOFTWARE THAT WILL ANALYZE
UNDERSTAND AND GENERATE LANGUAGES THAT HUMAN USE NATURALLY.
SPEECH RECOGNITION• PROCESS OF CONVERTING SOUND SIGNAL CAPTURED
BY MICROPHONE OR MOBILE/TELEPHONE TO A SET OF WORDS.
• 70-100 WORDS / MIN WITH ACCURACY OF 90%
COMPUTER VISION• ABILITY OF A MACHINE TO EXTRACT INFORMATION
FROM AN IMAGE THAT IS NECESSARY TO SOLVE A TASK
IMAGE ACQUISITION IMAGE PROCESSING IMAGE ANALYSIS IMAGE UNDERSTANDING
INTELLIGENT ROBOT• TEND TO MIMIC HUMAN
SENSING AND DECISION MAKING ABILITIES SO THAT THEY CAN ADOPT THEMSELVES TO CERTAIN CONDITIONS AND MODIFY THEIR ACTIONS.
EXPERT SYSTEMS
• A PIECE OF SOFTWARE WHICH USES DATABASES OF EXPERT KNOWLEDGE TO OFFER ADVICE OR MAKE DECISIONS IN SUCH AREAS AS MEDICAL DIAGNOSIS.
• THESE ARE SOFTWARES USED FOR DECISION MAKING
PERSONNAL ASSISTANTS
CORTANA SIRI GOOGLE NOW
MY POINT OF VIEW
I THINK AI WOULD BE GOOD FOR US. IT WILL ALLOW THE AI TO DO OUR BAD JOBS AND OTHER HARMFUL THINGS THAT AFFECT THE HUMAN BODY. FOR EXAMPLE LIKE MINING FOR DIAMONDS OR COAL.
MEMORY MANIPULATION
IN WEB & INTERNET
TO COME UNDER THE LIMELIGHT OF “SHORT TERM”
MEMORY OF TARGETED USER SHIP.ALSO CALLED GOOGLE EFFECT.
PRIMING TECHNIQUE• TO HIGHLIGHT SOME PART IN SUCH A WAY THAT USER’S
SUBCONSCIOUS MIND PONDERS OVER IT.
PRIMING AS A WAY TO HIGHLIGHT YOUR MESSAGE
PRIMING GONE WRONG
WEBSITE RE-DESIGN• DISRUPTS MEMORY PROCESSING OF USERS• CAN BE SUICIDAL IF GONE WRONG• HAS TO DO IN BITS
THE “WISH LIST” PHENOMENON• PEOPLE USED TO FORGET IN LATER VISITS WHAT THEY
HAVE LIKED IN PREVIOUS VISIT• THAN AMAZON.COM INTRODUCED “WISH LIST” FEATURE• SALES INCREASED BY 42%
SOCIAL MEDIA ANXIETY DISORDER• SOCIAL MEDIA ANXIETY DISORDER IS A MENTAL ILLNESS THAT IS RELATED
TO THE GENERALIZED SOCIAL ANXIETY, WHICH ACQUIRES WHEN THE SOCIAL MEDIA INTERFERES WITH MENTAL AND PHYSICAL HEALTH OF A HUMAN BEING .
• INDIVIDUALS WHO CAN RELATE THEMSELVES TO THE SOCIAL MEDIA ANXIETY DISORDER FEAR THAT INTERACTING WITHPEOPLE WILL GIVE RISE TO THE FEELINGS LIKE EVALUATION, JUDGMENTS, INFERIORITY AND SELF CONSCIOUSNESS.
• IT OFTEN LEADS TO THE FEELINGS LIKE DEPRESSION, INADEQUACY AND EMBARRASSMENT. AFTER DEPRESSION AND ALCOHOLISM, SOCIAL ANXIETY DISORDER IS CONSIDERED AS THE THIRD LEADING PSYCHOLOGICAL DISORDER IN W ORLD.
SYMPTOMS• BEING IN A GROUP OF FRIENDS AND INTERRUPTING THE CONVERSATION JUST TO SPEAK ABOUT THE
LATEST COMMENT ON THEIR FACEBOOK UPDATE.
• STAY AWAY FROM SOCIAL SITUATIONS WITH FAMILY AND FRIENDS JUST TO KEEP UP WITH THE NEWS ON TWITTER.
• CHECKING THE SOCIAL MEDIA SITES LIKE FACEBOOK AND TWITTER AMIDST AN IMPORTANT CHORE TO SEE IF SOMEONE HAS LEFT A COMMENT OR NOT.

HOW TO OVERCOME??1.ADMITTANCE OF HAVING A PROBLEM AND STAYING AWAY FROM DENIALS.
2. SPECULATE THE AMOUNT OF TIME YOU ARE SPENDING ON SOCIAL SITES. USE A TIMER AND RESTRICT THE USE OFTHE INTERNET FOR LONG HOURS.
3. TURN OFF ALL SOCIAL NOTIFICATIONS.
4. FORM A SCHEDULE FOR CHECKING THE FACEBOOK STATUS AND STICK TO IT AT ALL TIMES.
5. ASK OTHERS OR LEARN THROUGH YOUR BEHAVIOR IF YOU ARE RUNNING AWAY FROM A PROBLEM ON FACEBOOK OR OTHER SITES. LEARN TO DEAL WITH THE SITUATION RATHER THAN RUNNING AWAY.
6. TAKE A BREAK FOR A MONTH FROM FACEBOOK AND SEE HOW YOU FEEL DURING THE COURSE. TRY TO COPE UP WITH YOUR OFFLINE ACTIVITIES AT WORK, SCHOOL OR HOME AS WELL. YOU MAY BE SURPRISED WITH SOME REWARDING RESULTS.
7. MAKE A LIST OF ALL THE THINGS THAT YOU WOULD LOVE DOING OTHER THAN SPENDING SOME TIME ON SOCIAL MEDIA SITE LIKE FACEBOOK. START PLANNING AND STICK TO THE PLAN FOR CARRYING OUT THESE ACTIVITIES.
