Learning and remembering Flashcards
What are 2 key cognitive processes?
Learning and memory
What is learning?
A process by which information is acquired and which is observable in an organism’s behaviour
What is memory?
Encoding, storage, and retrieval of the learned information or, more broadly, previous experiences
What are neurobiological bases of learning and memory?
Changes in molecular, cellular and broader brain areas
What happened to patient K.F. (Shallice & Warrington, 1969) + how did this affect his short term and long term stores?
Left parieto-occipital lesion due to
a motorcycle accident
- Short-term storage impairment indicated by digit span of 2
- Long-term recall of words / stories was unimpaired
In what way was K.Fs damage to his short-term storage not general?
- short-term memory for visual stimuli was much better than for auditory letters or digits (Warrington & Shallice, 1972)
His deficit was limited to verbal stimuli and he performed at typical levels for non-verbal stimuli (Shallice & Warrington, 1974)
How did K.Fs brain damage challenge the modal model?
Suggested that the STS is not unitary, therefore supporting the working memory model (phonological loop and visuo-spatial sketchpad)
What are the 3 types of long term memory?
Declarative
Non-declarative
Emotional (conscious and unconscious)
What are 2 types of declarative memory?
episodic and semantic
What is episodic memory?
personal/autobiographical memory of events eg. going to school
What is semantic memory?
Facts/Knowledge eg. Paris is the capital of France
What is an example of non-declarative memory
Procedural memory
What is procedural memory?
Skills
Habits
Priming
Conditioning
What happened to patient H.M? (Scoville & Milner, 1957)
Bilateral hippocampus removed for treatment for epilepsy caused anterograde amnesia (inability to form new memories)
What did Maguire et al (1997) find in their experiment with 11 London Taxi Drivers?
Ppts recalled under PET:
- shortest legal route between 2 places
- famous London landmarks
- famous film sequences
Significant activation of the right hippocampus with legal routes
