INTEFERENCE THEORY

2 PIECES INFO CONFLICT LEAD FORGETTING 

EXPLAIN FORGETTING LTM

INFO AVALIABLE JUST CANT ACCESS IT 

INTEFERENCE MEMORIES HARDER ACCESS

OLD INTEFERE NEW 

'PRO' MEANNIG FORWARDS 

TEACHER LEARNED NEW NAMES IN PAST HARD REMEMBERING NAMES CURRENT CLASS

NEW INTEFRE OLD 

'RETRO' MEANING BACKWARDS 

TEACHER LEARNT NEW NAMES CANT REMEMBER OLD NAMES

MCGEOH & MCDONALD STUDY RETROACTIVE BY CHANGING SIMILARITY OF WORDS

PARTICIPANTS LEARN 10 WORDS TILL 100% ACCURACY - THEN NEW LIST

• 1 - SIMILAIR MEANINGS
• 2 - ANTONYMS 
• 3 - WORDS UNRELATED 
• 4 - NONSENSE SYLABLES 
• 5 - 3 DIGIT NUMBER
• 6 - NO NEW LIST

RECOLLECTION FIRST LIST DEPENDED ON SECOND LIST 

SIMILAIR MATERIAL PRODUCED WORST RECALL

SHOWS INTEFERENCE STRONGER - MEMORIES ARE SIMILAIR 

MAJORITY INTEFERENCE LAB EXPERIMENTS DESIGNED SO POSSIBILITY INTEFERENCE MAXIMISED 

PRACTICAL REASONS TIME IS SHORT 

PARTICIPANT MAY LEARN ONE LIST OF WORDS WAIT 20 MINUTES THEN ANOTHER THEN RECALL IN A FEW 

WHOLE EXPERIENCE LAST OVER 1 HOUR 

TULVING & POSTKA GAVE PARTICIPANTS 5 LIST OF 24 WORDS IN 6 CATEGORIES 

CATEGORIES NOT EXPLICIT ASSUMED OBVIOUS 

RECALL 70% FISRT MEMORY FELL AS LIST GOT BIGGER

END GOT CUED RECALL TEST - RECALL ROSE 70% 

THOUSANDS STUDIES - INTEFERENCE RESULTS MOST CONSISTENT

V. LIKELY COMMON WAYS FORGET INFO FROM LTM

LAB EXPERIMENTS CONTROL EFFECTS 

CONFIDENCE VAID EXPLANATION 

STIMULUS DISTANT TO REALITY 

BETTER USE FACE, BIRTHDAY ETC.

ARTIFICIAL TASK IN LAB MAKES INTEFERENCE MORE LIKELY 

NOT AS LIKELY IN EVERYDAY LIFE

BADDELEY & HITCH RUGBY PLAYERS REMEMBER NAMES TEAMS PLAYED SO FAR IN SEASON

SOME PLAYERS MISSED - LAST GAME OVER 3 WEEKS AGO

RESULTS ACCURATE RECALL DIDNT DEPEND WHEN MATCH WAS BUT WHEN THEY PLAYED IN MEANTIME

INTEFERENCE APPLY SOME SITUATIONS
