Along with his simple recognition memory, motor memory helped smooth challenges Henry faced as he aged, such as learning to use a walker.

What did Clive Wearing teach us about the function of the hippocampus? Answer: Clive Wearing taught us about hippocampal dependent formation of long term memory. Because the hippocampus is important for the creation of long term memories, his injury resulted in an inability to form new explicit memories following the injury, also called anterograde amnesia.

What did researchers learn about the role of the hippocampus and memory from HM quizlet? Cognitive psychologists have categorized memories into different types.
