Amnesia (PSYC1011)


Damage to the hippocampus and temporal lobes results in amnesia

  • Retrograde; Inability to remember things that happened before the damage
  • Anterograde; Inability to remember things that happen after the damage (more permanent)

Memento is an example of anterograde amnesia, as is Clive Wearing, a man who's missing his temporal lobe and hence has only a maximum of 30 seconds of memory.

Amnesic patients were tested against a control group for the following:

  • Recall
  • Recognition
  • Word fragment completion

With the results such that patients with amnesia can't consciously remember their past, but their performance on "implicit" tasks is affected by their past. (Makes sense, as priming is procedural, not declarative, so doesn't need to be consciously accessible).
