Encoding Failure
Failure to store sufficient information to form a useful memory
Herman Ebbinghaus
Tested his own memory at different intervals of learning by using nonsense syllables. He plotted a forgetting curve (forgetting is rapid at first and is followed by a slow decline
Memory Traces
Physical changes in nerve cells or brain activity that take place when memories are stored
Memory Decay
The fading or weakening of memories assumed to occur when memory traces become weaker
Disuse
Theory that memory traces weaken when memories are not periodically used or retrieved
Retrieval Cues
Stimuli associated with a memory. Retrieval cues usually enhance memory
State-dependent Learning
Memory influenced by one's physical state at the time of learning and at the time of retrieval. Improved memory occurs when the physical states match
Interference
The tendency for new memories to interfere with the retrieval of older memories, and the reverse
Retroactive Interference
The tendency for new memories to interfere with the retrieval of old memories
Proactive Interference
The tendency for old memories to interfere with the retrieval of newer memories
Positive Transfer
Mastery of one task aids in the learning or performing of another
Negative Transfer
Mastery of one task conflicts with learning or performing another
Repression
Unconsciously pushing unwanted memories out of awareness
Suppression
An active conscious effort to put something out of mind or to keep it form awareness
Retrograde Amnesia
Loss of memory for events that preceded a head injury or amnesia-causing event
Anterograde Amnesia
Loss of the ability to form or retrieve memories for events that occur after an injury or trauma
Consolidation
Process by which relatively permanent memories are formed in the brain
Hippocampus
A brain structure associated with emotion and the transfer of information from the short-term memory to long-term memory
Flashbulb Memory
Especially vivid memory created at a time of high emotion. Have the tendency to not always be accurate
Stressful situations activate what system?
The limbic system.

Heightened activity in the limbic system intensifies memory consolidation

Memories are stored in these two parts of the brain:
The basal ganglia and the cerebellum
An Aplysia
The sea animal that allows scientists to study memory as it occurs in single nerve cells
Edectic Imagery
The ability to retain a "projected" mental image long enough to use it as a source of information (they are seen on a plain surface and are more common in children)
Mental images
Mental pictures or visual depictions used in memory
Exceptional Memorizers
Have naturally superior memory often using mental images, they don't have superior intellectual abilities, they have specialized interests and knowledge that make it easier to encode and recall certain information
Mnemonics
Any kind of memory system or aid
The ability to __________________________________________________________ underlies expertise in many fields
organize memories into chunks
Spaced Practice
a practice schedule that alternates study periods with brief rests
Massed Practice
A practice schedule in which studying continues for long periods, without interruption
