Term
Storage
Definition
Retention of information over time and how this info is represented in memory

Term
Short Term Memory
Definition
Limited capacity memory system in which info is usually retained for only as long as 30 sec. unless we use strategies to retain it longer
Term
Working Memory
Definition
Three part system that allows us to hold info temporarily as we perform cognitive tasks. Mental workbench on which the brain manipulates and assembles info to help us understand make decisions and solve problems
Term
Phonological loop
Definition
briefly stores speech based info about language
Term
Visuospatial working memory
Definition
Stores visual and spatial info including visual imagery
Term
Central Executive
Definition
Integrates info not only from the phonological loop and visuospatial working memory but also from long term memory

Connectionism
Definition

Term
Interference Theory
Definition
Theory that people forget not because memories are lost from storage but because other info gets in the way!
Term
Proactive Interference
Definition
Situation in which material that was learned earlier disrupts the recall of material that was learned later
Term
Retroactive interference
Definition
Situation in which material that was learned later disrupts the retrieval of info that was learned earlier
Term
Decay Theory
Definition
Theory Stating that when we learn something new a memory trace forms. Over time the trace disintegrates increasing forgetting
Term
