• HM by Milner’s case was a Longitudinal case study that used Method Triangulation
• HM was hit by a cyclist when he was 7, 3 years later, when he was 10, he began to have epileptic attacks, and 17 years later by age 27, his quality of life was incapacitated by his seizures
• Medication did not help with his epilepsy
• Desperate, he and his family agreed to an ablation surgery by William Scoville that removed scar tissue from the medial temporal lobe of HM milner’s brain
• This surgery caused HM to develop anterograde amnesia - Or a type of memory loss that hinders short term memory, meaning you can’t form new memories or retain any new information.
• HM was able to remember details of his childhood, and everything that happened before the surgery, and even his personality was largely unchanged, but he was not able to develop new memories
• The aim of the case study was to understand the effects the surgery had on HM
• Milner used METHOD TRIANGULATION

→ IQ testing (Psychometric) → Interviews with HM and his family → Memory recall tests and learning tasks like reverse mirror drawing

→ An MRI of his brain to determine the extent of damage done

• HM could not acquire new episodic knowledge - Knowledge of new events, and new semantic memory (general knowledge)
• In 1992, and 2003 after, An MRI was carried out on HM’s brain to visualise the damage done to his brain
• After the MRI, it was possible to see that part of HM’s temporal lobe, which was what was operated on were damaged - Especially the hippocampus in the temporal lobe
• The damage was less extensive than originally estimated by Scoville though
• CANNOT BE REPLICATED
• Utilised a lot of method triangulation
• EXTREMELY HIGH ECOLOGICAL VALIDITY
• All ethical standards were met - Milner's research met high ethical standards of consent, confidentiality, and protection from harm.
