Term
2 qualitatively different systems of information storage in humans
Definition
declarative memory & nondeclarative memory
Term
declarative memory
Definition
the storage & retrieval of material that is available to consciousness & can in principle be expressed by language (i.e. "declared")
Term
nondeclarative memory (AKA procedural memory)
Definition
not available to the consciousness, at least not in any detail
Term
Would the words to a song be in your declarative or nondeclarative memory?
Definition
declarative
Term
Would the physical memory of how to sing a song be in your declarative or nondeclarative memory?
Definition
nondeclarative
Term
In addition to the types of memory defined by the nature of what is remembered, memory can also be categorized according to the _____
Definition
time over which it is effective
Term
immediate memory
Definition
the first class of temporal classes of memory; the routine ability to hold ongoing experiences in mind for fractions of a second
Term
Is the capacity for the immediate memory very large or very small?
Definition
very large!
Term
working memory (AKA short-term memory)
Definition
the second temporal category; the ability to hold & manipulate information in mind for seconds to minutes while it is used to achieve a particular goal
Term
How long is the normal digit-memory span?
Definition
7 - 9 numbers
Term
long-term memory
Definition
the third temporal category; entails retaining information in a more permanent form of storage for days, weeks, or even a lifetime
Term
engram
Definition
the physical embodiment of any memory in neuronal machinery; depends on changes in the efficacy of synaptic connections and/or the actual growth & reordering of such connections
Term
memory consolidation
Definition
the way in which immediate & short-term memories are gradually encoded as long-term memories
Term
priming
Definition
one approach to exploring the continual transfer of information from immediate to short-term memory to long-term memory; a change in the processing of a stimulus due to a previous encounter with the same or a related stimulus with or without conscious awareness of the original encounter
Term
To what three factors is priming resistant?
Definition
brain injury, aging, & dementia
Term
How reliable is information stored in priming?
Definition
not particularly reliable
Term
The strategy of _____ is used by professional "mnemonists" who amaze audiences by prodigious feat of memory
Definition
association
Term
The capacity to remember something can be increased if the information being remembered is given _____
Definition
significance/meaning
Term
conditioned learning
Definition
the generation of a novel response that is gradually elicited by repeatedly pairing a novel stimulus with a stimulus that normally elicits the response being studied
Term
classical conditioning
Definition
occurs when an innate reflex is modified by associating its normal triggering stimulus with an unrelated stimulus; by virtue of the repeated association, the unrelated stimulus eventually triggers the original response
Term
What is the most famous example of classical conditioning?
Definition
Pavlov's dogs (bell & food used to have bell alone elicit salivation)
Term
operant conditioning
Definition
the altered probability of a behavioral response engendered by associating the response with a reward or punishment
Term
extinction
Definition
if the conditioned animal performs the desired response but the reward is no longer provided, the conditioning gradually disappears
Term
What happens to unused or unrehearsed memories?
Definition
they are forgotten over time
Term
superior autobiographical memory
Definition
inability to forget
Term
What did the psychological subject "S" & Marilu Henner have?
Definition
superior autobiographical memory
Term
amnesia
Definition
a pathological cause of memory loss
Term
anterograde amnesia
Definition
an inability to establish new memories following neurological insult
Term
retrograde amnesia
Definition
difficulty retrieving memories established prior to the precipitating neuropathology
Term
Is long-term storage of declarative information in the brain stored in the midline diencephalic & medial temporal lobe structures that are affected in anterograde amnesia?
Definition
no!
Term
mass action principle
Definition
any degradation in learning & memory depends on the amount of cortex destroyed; Lashley
Term
Where are long-term declarative memories widely stored?
Definition
in the cerebral cortex
Term
Are declarative & non-declarative memories stored together?
Definition
no!
Term
What decreases in human brains as we age?
Definition
the connections (synapses) between neurons
