PSYCH 2010 Lecture Notes - Lecture 13: Sensitivity And Specificity, Sensory Memory, Limbic System
Document Summary
Studying memory: information processing models: memory, encoding, storage, retrieval. Sensory memory: the longer the delay, the greater the memory loss. Sensory memories: the duration of sensory memory varies for the different senses, different types, iconic, echoic, hepatic. Storing memories in the brain: memories are written into the brain, electrical stimulation during brain surgery causes memory recall, but not stored in a specific place, even after removing parts of the brain, animals retain partial memory. Synaptic changes: long-term potentiation (ltp, synaptic enhancement after learning, an increase in neurotransmitter release of receptors on the receiving neuron, writing of memories = synapse changes. Hippocampus: a neural center in the limbic system that processes explicit memories, explicit memories. Implicit memory: patient hm is unable to make new memories that are declarative (explicit), but he can form new memories that are procedural (implicit) Cerebellum: a neural center in the hindbrain that processes implicit memories.
