DNA
a molecule containing genetic information
Genes

long - term memory
permanent information that is stored in the memory system
working memory
memory that focuses on incoming auditory and visual information
automatic processing
unconscious encoding of incidental information
effortful processing
encoding that requires attention
rehearsal

retention independent of conscious recollection
explicit memory
memory of facts and experiences
hippocampus
a neural center that is located in the limbic system
recall
a measure of memory where a person retrieve earlier information

priming
the activation of particular associations in memory

the sense of experiencing something before
mood-congruent memory
able to recall experiences that are consistent with one’s mood
proactive interference
disruptive effect of prior learning new information
retroactive interference
disruptive effect of new learning on the recall of old information
