BIOL 1F25 Lecture Notes - Lecture 9: Short-Term Memory, Memory Span
Document Summary
Bio 1f25 notes -> human learning and memory. H. m. (henry) is a 27 year old assembly line worker. Suffered from untreatable seizures for more than 10 years. Removal of the medial portion of temporal lobes greatly reduced seizures. Two different ways of learning: what the world is about e. g. knowledge of people, places and things available to consciousness. Explicit or declarative memory: how to do things e. g. motor skills, and things not available to consciousness. H. m. = no ability to form new explicit memories. Hippocampus: area of brain involved in learning that requires a conscious record e. g. faces, names (explicit/declarative memory) Involved in process of acquiring and storing long-term memories. How does hippocampus contribute to memory: develops map of stored memories, maintains a temporary storage, may be used to recall memories - recently made memories are sensitive to disruption. Memory - short term vs long term. Short term memory (stm): lasting only minutes. Thought to have a severely limited capacity.
