Memory Flashcards
Retrograde Amnesia
Difficulty retrieving memories formed before the onset of amnesia
Anterograde Amnesia
The inability to form new memories beginning with the onset of a disorder
Declarative Memory
Facts and information acquired by learning
Procedural Memory
Memory about perceptual or motor procedures
Confabulate
Fill a gap in memory with a falsification that they seem to accept as true
Episodic Memory
Memory of a particular incident or a particular time and place
Semantic Memory
Generalized memory- knowing the meaning of a word without knowing where or when you learned that word.
Priming
Exposure to a stimuli facilitates subsequent responses to the same or a similar stimulus
Conditioning
A form of learning in which an organism comes to associate two stimuli or a stimulus and a response
Iconic Memories
A brief type of memory that stores the sensory impression of a scene
Working Memory
Holds memories available for ready access during performance of a task
Primacy Effect
The superior performance seen in a memory task for items at the start of a list; usually attributed to long-term memory
Recency Effect
Superior performance seen in a memory task for items at the end of a list; attributed to short term memory
Stages of Memory Formation
Encoding: Information is passed into short-term memory
Consolidation: Information in STM or ITM is transferred to LTM
Retrieval: A stored memory is used by an organism
Engram
The physical basis of a memory in the brain
Hippocampus is important for…
Memory consolidation
Permanent storage of information tends to be in…
The regions of the cortex where the information was first processed and held in short-term memory
Latent Learning
Learning that has taken place but has not (yet) been demonstrated by performance
Neuroplasticity
The ability of the nervous system to change in response to experience or environment
Non-associative Learning
Presentation of a particular stimulus alters the strength or probability of a response according to the strength and temporal spacing of that stimulus; includes habituation and sensitization
Habituation
An organism becomes less responsive following repeated presentations of a stimulus
Dishabituation
The restoration of response amplitude following habituation
Sensitization
The response is greater than the baseline level because of prior stimulation
Hebb
Proposed that when a presynaptic neuron repeatedly activates a postsynaptic neuron, the synaptic connection between them will become stronger and more stable
