Types of LTM

• LTM - Procedural (skills learnt)

  Non - Declarative and implicit ( difficult to access consciously). Its knowing how - no conscious effort or attention. Memories for motor movement. Automatic like riding a bike
• Types of LTM - Episodic

  Declarative as can be explained verbally and can be consciously inspected. Knowing that - refers to memories relating to specifically to you. e.g. going on a memorable holiday with family
• Types of LTM - Semantic

  Are declarative and explicit can be easily put into words. - Relates' to meaning and fact based memonies for meaninful information. - knowledge as can be shared with others. - e.g. 2+2 and that capital of England is London - Semantic memones are said to begin as episodic which is personal.
• Evaluation - Strengths

  Case Study support- HM had poor semantic and episodic memory but through practice he learned motor skills which is procedural memory. He became better at tracing a star in a mirror with practice. but he had no recollection of doing the task. Dementia supports that LTM is separated into 3 types.
• Evaluation - Weakness

  Methodological issues - small samples, bias as just male, researcher bias in presentation and interpretation of data. No evidence of memory before accident and impossible to replicate.
• Low generalisability

  -only one individual who has lived this event as personal and unique and would be unethical if someone was to replicate it.

  -This means findings about LTM can't be generalised to other people in the population.
