Atkinson-Shiffrin’s Three Stage Processing Model of Memory Sensory – Short term (working memory RAM) – Long term
Encoding: Getting Information In Exploring in Modules, Module 18 Automatic Processing Effortful Processing
Exploring in Modules, Module 18 Automatic vs. Effortful Processing Rehearsal
Rehearsal Issues Exploring in Modules, Module 18 Next-in-line-effect – poorest memories of those just in-front of us. Spacing effect – best for retention is to spread rehearsal out. Serial position effect – Best memories for first and last items on a list.

Encoding Strategies: Improving memory performance Exploring in Modules, Module 18 Encoding Meaning (semantic encoding) – meaning is remembered not so much the exact words Encoding Imagery: i.e. mnemonic devices and story telling Organizing Information for Encoding Chunking Hierarchies

Long-Term Memory Limitless Exploring in Modules, Module 18
Storing Memories in the Brain Exploring in Modules, Module 18 Synaptic Changes

Stress Hormones and Memory Stress hormones – more glucose in blood stream results in more fuel for brain activity. Attach emotion to event. Exploring in Modules, Module 18
Memory Subsystems Amnesic patients still have nondeclarative memory means that memory is not a unified system.
