Short-term memory
A memory storage system that records information from the senses for up to three seconds
Long-term memory (LTM)
A relatively permanent memory storage system that can hold vast amounts of information for many years
Iconic memory
A fleeting sensory memory for visual images that lasts only a fraction of a second
echoic memory
A brief sensory memory for auditory input that lasts only two to three seconds
The process of grouping distinct bits of information into larger wholes or chunks to increase short-term memory capacity
maintenance rehearsal
The use of sheer repetition to keep information in short-term memory
Working memory
Term used to described short-term memory as an active workspace where information is accessible for current use
serial-position curve
A U-shape pattern indicating the tendency to recall more items from the beginning and end of a list than from the middle
Elaborative rehearsal
A technique for transferring information into long-term memory by thinking about it in a deeper way
Procedural memory
Stored long-term knowledge of learned habits and skills

A form of explicit-memory retrieval in which items are represented to a person who must determine if they were previously encountered.
Encoding specificity
The principle that any stimulus encoded along with an experience can later jog one's memory of that experience.
Forgetting curve
A consistent pattern in which the rate of memory loss for input is steepest right after input is received and levels off after time
proactive interference
The tendency for previously learned material to disrupt the recall of new information
Retroactive interference
The tendency for new information to disrupt the memory of previously learned material
Memory aids designed to facilitate the recall of new information
Preconceptions about persons, objects, or events that bias the way new information is interpreted and recalled.
Autobiographical memory
The recollections people have of their own personal experiences and observations
flashbulb memories
