Forgetting Flashcards
What can be impacted by interference?
Accuracy,
Peterson and Peterson 1959 found only 50% accuracy when did tractor- 6 seconds long,
Close to 0% when duration- 18 seconds.
What did Nairne eat al 1999 find?
Minimised overlap between stimuli, used different words.
Accuracy is very high up to durations of over 1.5 minutes.
When interference is limited= little decay.
Why are some memories forgotten?
Often don’t encode the necessary info to remember the event or object
What is proactive interference?
Old me memories interfere with the ability to remember bee memories
What is retroactive interference?
New memories interfere with old memories
What is amnesia caused by?
Brain damage and sever impairment to LTM
What is Karsakoff syndrome?
Leads to damage of hippocampus and diecephalon
What is retrograde amnesia?
Affects episodic memories, damage to cortical and neocortical structures.
Inability to recall info and events
What is anterograde amnesia?
Problem with consolidation of memories,
Inability to form new memories,
Failure to encode info,
Damage to subcortical areas
What is ribots law?
Temporal gradient of amnesia
Recent memories more likely to be lost than more remote memories
What is consolidation?
Makes memory for an event enduring.
Process of info being transferred from Ken region to another and gradual reorganisation of brain regions to support memory.
What is hippocampal consolidation?
Coding of bee info into hippocampus. Rapid processes, cellular and subcellular level
What is systems consolidation?
Transferring info from hippocampus to other regions for Long term storage
What’s the process of consolidation?
LTM stored in cortex,
Forming trace takes time,
Interactions between hippocampus and (neo) cortical regions crucial in formation of memories,
Continued activation, cortical sites communicate,
Consolidation continues.
What is the multiple trace theory?
Nasal and mosoevith 1997-1998
Consolidation creates multiple traces of memory in brain,
Damage to hippocampus removes some traces
