The process of acquiring information and transferring it into LTM
Retrieval
Transferring information from LTM into working memory
Maintenance rehearsal
Repeating information without considering its meaning or making connections with other information, helps maintain information in STM but is not an effective way of transferring information into LTM
Elaborative rehearsal
Finding a way to relate information to something meaningful, such as connecting it to something you already know, is a better way to establish long-term memories
Levels of processing theory
Memory depends on how information is encoded or programmed into the mind
Shallow processing
Involves little attention to meaning
Deep processing
Involves close attention and elaborative rehearsal
Memory was better following deep processing than following shallow processing (Craik and Tulving experiment)
Evidence that encoding influences retrieval
Forming visual images
Linking words to yourself
Generating information (the generation effect)
Organizing information
Relating words to survival value
Practicing retrieval (the retrieval practice effect or the testing effect)
Five memory principles that can be applied to studying
Elaborate
Generate and test
Organize
Take breaks
Avoid "illusions of learning"
Note taking by hand results in better test performance than note taking by laptop, due to deeper encoding for handwritten note taking
Retrieval cues
Aids in retrieving long-term memories
Retrieval can be increased by matching conditions at retrieval to conditions that existed at encoding (encoding specificity, state-dependent learning, and matching type of processing)
Encoding specificity
We learn information along with its context
Godden and Baddeley's diving experiment and Grant's studying experiment illustrate the effectiveness of encoding and retrieving information under the same conditions
State-dependent learning
A person's memory will be better when his or her internal state during retrieval matches the state during encoding
Eich's mood experiment supports the idea of state-dependent learning
Matching types of processing
Memory performance is enhanced when the type of coding that occurs during acquisition matches the type of retrieval that occurs during a memory test
The results of an experiment by Morris support the idea of transfer-appropriate processing
Consolidation
The process that transforms new memories from a fragile state into a more permanent state
Müller and Pilzecker's experiment illustrated how memory is decreased when consolidation is disrupted
Synaptic consolidation
Involves structural changes at synapses
Systems consolidation
Involves the gradual recognition of neural circuits
Hebb's idea
The formation of memories is associated with structural changes at the synapse, which are then translated into enhanced nerve firing, as indicated by long-term potentiation
Standard model of consolidation
Memory retrieval depends on the hippocampus during consolidation but that after consolidation is complete, retrieval involves the cortex, with the hippocampus no longer being involved
Consolidation is facilitated by sleep, and material people expect they will be asked to remember later is more likely to be consolidated during sleep
Reconsolidation
When a memory is retrieved (remembered) it becomes fragile, like it was when it was originally formed, and that when it is in this fragile state, it needs to be consolidated again
Alain Brunet & coworkers (2008) tested the idea that reactivation of a memory followed by reconciliation can help alleviate the symptoms of Post Traumatic Stress Disorder
Hupbach emphasizes that memory updating is influenced by the strength of the memory, with strong memories being more resistant to change, and the extent of memory reactivation during new learning predicts the amount of memory updating
Long-term memory (LTM)
A system that is responsible for storing information for long periods of time, described as an "archive" of information about past events in our lives and knowledge we have learned
Serial position curve
Created by presenting a list of words to a participant, one after another, and then having the participant write down all the words he or she remembers, in any order
Primary effect
Participants are more likely to remember words presented at the beginning of a sequence
Recency effect
Better memory for the stimuli presented at the end of a sequence
Coding
The form in which stimuli are represented
Visual coding
Coding in the mind in the form of a visual image
Auditory coding
Coding in the mind in the form of a sound
Semantic coding
Coding in the mind in terms of meaning
Visual coding in STM is illustrated by remembering a pattern by representing it visually in your mind, and visual coding in LTM occurs when you visualise a person or place from the past
Auditory coding in STM is illustrated by Conrad's demonstration of the phonological similarity effect, and auditory coding in LTM occurs when you "play" a song in your head
Wickens' experiment provides an example of semantic coding in STM, and Sachs' study demonstrated semantic coding in LTM
