PSY E111 Chapter Notes - Chapter 1: Flashbulb Memory, Long-Term Potentiation, Perirhinal Cortex
Document Summary
Memory is any indication that learning as persisted over time. It is our ability to store and retrieve information. The atkinson/schiffrin three stage model of memory includes sensory memory, short-term memory, and long-term memory. Working memory is typically limited to a capacity of 7 plus/minus 2 but the duration is only around 20 seconds. Chunking numbers together helps you remember them (puts them in familiar, manageable units) Primacy effect early items receive more rehearsal and are more likely to be. Recency effect just heard items can be retrieved directly from working memory transferred to long-term stage. Retrieval from long-term memory specifically activated the hippocampus. Retrieval from working memory specifically activated the perirhinal cortex. Long term potentiation (ltp) refers to synaptic enhancement after learning. An increase in neurotransmitter release or receptors on the receiving neuron indicates strengthening of synapses. Rehearsal: effortful learning usually requires rehearsal or conscious repetition. Ebbinghaus studied rehearsal by using nonsense syllables.
