Types of Long Term Memory

Cards (9)

  • what are the three types of long term memory
    ->semantic
    ->procedural
    ->episodic
  • describe the episodic LTM
    ->it refers to any events that can be reported from a person's life
    ->e.g, times, places involved-for example, riding a camel for the first time in Dubai
    ->it is a type of declarative memory, i.e it can be explicitly inspected and recalled consciously.
  • give the other features of the episodic LTM
    ->split into; autobiographical episodic memory (memories of specific episodes of one's life)
    ->experimental episodic memory (where learning a fact (a semantic memory) has been associated with memory of the specific life episode where it was learned
    ->flashbulb memories; they are detailed autobiographical episodic memories that are stored permanently in LTM when they are first learned, often because they were of emotional or historical importance in that person's life
  • describe the semantic LTM
    ->it is a type of declarative (explicit, consciously recalled) memory
    ->the conscious recall here is facts that have meaning
    ->e.g capital of France is Paris
  • describe the procedural memory
    ->describes our implicit knowledge of tasks that usually do not require conscious recall to perform them
    ->e.g, riding a bike- we can perform this with ease but struggle to consciously recall how to manage the task
  • in what brain region are the three types of LTM associated with?
    ->episodic- hippocampus
    ->semantic-temporal lobe
    ->procedural-cerebellum and motor cortex
  • supporting evidence for the different types of LTM
    ->Tulving (1994) did PET scans whilst asking participants to perform memory tasks and found that episodic and semantic memories were recalled from the pre-frontal cortex and stores it in the hippocampus, whereas procedural memories are stored in the cerebellum
    ->this is supporting evidence for Tulving's theory as it suggest that the LTM has more than one store
  • case study, patient HM
    ->Patient HM had his hippocampus surgically removed to cure his epilepsy; the surgery was a success, but was left unable to permanently store new info and could only form episodic memories that lasted a matter of a minute
    ->this case also supports the theory, because patient HM showed that despite one store being damaged, but the other stores weren't
  • case study of Clive Wearing
    ->while he doesn't have the episodic and semantic LTM, his procedural LTM is still intact.
    ->as he can presumably write, and play the piano, this shows that after the illness, his skills haven't left him
    ->this increases the validity of this theory
