Unit Six: Cognition Flashcards
Memory
the persistence of learning over time through the encoding, storage, and retrieval of information
Encoding
the processing of information into the memory system—for example, by extracting meaning
Storage
the process of retaining encoded information over time
Retrieval
the process of getting information out of memory storage
Parallel processing
the processing of many aspects of a problem simultaneously; the brain’s natural mode of information processing for many functions, including vision. Contrasts with the step-by-step (serial) processing of most computers and of conscious problem solving
Connectionism
views memories as products of interconnected neural networks
Sensory memory
the immediate, very brief recording of sensory information in the memory system
Short-term memory
activated memory that holds a few items briefly, such as the seven digits of a phone number while dialing, before the information is stored or forgotten.
Long-term memory
the relatively permanent and limitless storehouse of the memory system. Includes knowledge, skills, and experiences
Working memory
a newer understanding of short-term memory that focuses on conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory
Information processing models
analogies that compare human memory to a computer’s operations
Explicit memories
memory of facts and experiences that one can consciously know and “declare.” (Also called declarative memory.)
Effortful processing
encoding that requires attention and conscious effort
Automatic processing
unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings
Implicit memories
retention independent of conscious recollection. (Also called nondeclarative memory.)
Iconic memory
a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second
Echoic memory
a momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds and words can still be recalled within 3 or 4 seconds
Chunking
organizing items into familiar, manageable units; often occurs automatically
Mnemonics
memory aids, especially those techniques that use vivid imagery and organizational devices
Spacing effects
the tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice
Testing effects
enhanced memory after retrieving, rather than simply rereading, information. Also sometimes referred to as a retrieval practice effect or test-enhanced learning
Shallow processing
encoding on a basic level based on the structure or appearance of words
Deep processng
encoding semantically, based on the meaning of the words; tends to yield the best retention
Hippocampus and side for visual vs verbal
a neural center located in the limbic system; helps process explicit memories for storage-> storage is elsewhere
Visual is right, verbal is left
Role of cerebellum in memory
implicit memories created by classical conditioning
Role of basal ganglia in memory
procedural memories for skills
Infantile amnesia
we do not have conscious memories of our first three years of life (we retain implicit while removing explicit)
Flashbulb memories
a clear memory of an emotionally significant moment or event
Long-term potentiation (LTP)
an increase in a cell’s firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory
Recall
a measure of memory in which the person must retrieve information learned earlier, as on a fill-in-the-blank test
Recognition
measure of memory in which the person need only identify items previously learned, as on a multiple-choice test
Relearning
a measure of memory that assesses the amount of time saved when learning material again
Priming
the activation, often unconsciously, of particular associations in memory
Mood-congruent memory
the tendency to recall experiences that are consistent with one’s current good or bad mood
Serial position effect
our tendency to recall best the last (a recency effect) and first (a primacy effect) items in a list
Atkinson and Shriffrin Theory
three types of memory- sensory, short-term, long-term
Central executive
handles focus, what we are trying to remember
Anterograde amnesia
an inability to form new memories
Retrograde amnesia
an inability to retrieve information from one’s past
