CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -After the surgery, which was partially successful in controlling his seizures, Molaison developed severe anterograde amnesia: although his working memory and procedural memory were intact, he could not commit new events to his explicit memory.

Detailed explanation-2: -H.M. suffered a dense and persistent anterograde amnesia following bilateral medial temporal lobectomy in 1953 to treat intractable epilepsy (Scoville & Milner, 1957). His scientific fame derives from the dramatic demonstration of the critical role that the mesial temporal lobe structures play in learning and memory.

Detailed explanation-3: -In contrast, H. M’s inability to form new memories after his operation, known as anterograde amnesia, was the result of his loss of hippocampus. This meant that H.M could not learn new words, facts, or faces after his surgery, and he would even forget who he was talking to the moment he walked away.

Detailed explanation-4: -Results: H.M. lost the ability to form new memories. This is called anterograde amnesia. He could do a task, and even comment that it seemed easier than he expected, without realising that he had done it hundreds of times before. His anterograde procedural memory was totally affected.

Detailed explanation-5: -Subsequently, the terms declarative and nondeclarative were introduced with the idea that declarative memory refers to the kind of memory that is impaired in H.M. and is dependent on the medial temporal lobe. Nondeclarative memory is an umbrella term referring to additional memory systems.
