Definition
Interference with retention of old information due to acquisition of new information

The span of short-term memory, according to George Miller: Seven plus or minus two pieces of information
Term
Chunking
Definition
organizing information into meaningful groupings allowing us to extend the span of short-term memory

Recall
Definition
Generating previously remembered information
Term
Recognition

Term
Relearning
Definition
Reacquiring knowledge that we'd previously learned but largely forgotten over time
Term
Encoding specificity
Definition
Phenomenon of remembering something better when the conditions under which we retrieve information are similar to the conditions under which we encoded it
Term
Context-dependent Learning
Definition
Superior retrieval of memories when the external context of the original memories matches the retrieval context
Term
State-Dependent Learning
Definition
Superior retrieval of memories when the organism is in the same physiological or psychological state as it was during encoding
