Memory Chapter Flashcards
(26 cards)
Coding
The format in which the information is stored in various methods.
Capaicity
The amount of info that a memory store can hold.
Duration
The length of time information can be held in memory.
STM
Limited capacity, coding is mainly acoustic, capacity between 5-9 items on average. Duration about 18-30 seconds.
LTM
Permanent memory store. Coding is semantic, unlimited capacity, up to a lifetime.
MSM
Representation where memory is in 3 stores:sensory register, STM, LTM. Describes how info is transferred from one store to another and how it’s forgotten.
Sensory Register
Stores memory in each of our 5 senses. Iconic is visual and Echoic is acoustic. Massive capacity, info lasts for less than 1/2 a second.
Episodic Memory
LTM for personal events. Have to be retrieved consciously with effort.
Semantic Memory
LTM for knowledge of the world. Need to be recalled deliberately.
Procedural Memory
LTM how to do things, unconscious.
WMM
Representation of STM, suggesting that it’s a dynamic processor processed by different sub-units coordinated by the central executive.
Central Executive
Co-ordinates activites of the 3 subsystems of memory, controls slave systems.
Phonological Loop
Processes information in terms of sound (written and spoken) divided into phonological store and the articulatory process.
Visuo-spatial Sketchpad
Processes visual and spatial information in a mental space often called our ‘inner eye’.
Episodic Buffer
Brings together material from the other subsystems into a single memory (compared to just strands). Provides a bring between working memory and LTM.
Interference
Forgetting because one memory blocks another, causing memories to be distorted or forgotten.
Proactive Interference
Forgetting when an older memory disrupts the recall of newer memories, even more so when the memories are similar.
Retroactive Interference
Forgetting when an newer memory disrupts recall of an older on, again more so when it’s similar.
Retrieval Failure
Forgetting when we don’t have any cues to access the memory.
Cue
A trigger for information to access a memory. They may be meaningful or indirectly encoded.
EWT
People remembering the details of accidentsand crimes, they’ve observed. The accuracy can be affected by many factors like: misleading information, leading questions and anxiety.
Misleading Informaton
Incorrect information given to the eyewitness called ‘post-event dicussion’.
Leading Question
Phrased in a many that suggests a certain answer.
Post-Event Dicussion
When there is more than 1 witness they talk about what they have seen. This might influence the accuracy of each witnesses recall.
