Memory Flashcards
relearning
a measure of memory that assesses the amount of time saved when learning material for a second time.
retrograde amnesia
an inability to retrieve information from one’s past.
anterograde amnesia
an inability to form new memories.
hippocampus
a neural center located in the limbic system; helps process explicit memories for storage.
mnemonics
memory aids, especially those techniques that use vivid imagery and organizational devices.
implicit memory
retention independent of conscious recollection. (Also called nondeclarative memory.)
retroactive interference
the disruptive effect of new learning on the recall of old information.
long-term potentiation
an increase in a cell’s firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory.
automatic processing
unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings.
explicit memory
memory of facts and experiences that one can consciously know and “declare.” (Also called declarative memory.)
retrieval
the process of getting information out of memory storage.
chunking
organizing items into familiar, manageable units; often occurs automatically.
recall
a measure of memory in which the person must retrieve information learned earlier, as on a fill-in-the-blank test.
source amnesia
attributing to the wrong source an event we have experienced, heard about, read about, or imagined. (Also called source misattribution.) Source amnesia, along with the misinformation effect, is at the heart of many false memories.
serial position effect
our tendency to recall best the last and first items in a list.
spacing effect
the tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice.
long-term memory
the relatively permanent and limitless storehouse of the memory system. Includes knowledge, skills, and experiences.
shallow processing
encoding on a basic level based on structure or appearance of words.
proactive interference
the disruptive effect of prior learning on the recall of new information.
deep processing
encoding semantically, based on the meaning of the words; tends to yield the best retention.
testing effect
enhanced memory after retrieving, rather than simply reading, information. Also sometimes referred to as a retrieval practice effect or test-enhanced learning.
sensory memory
the immediate, very brief recording of sensory information in the memory system.
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.
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 longterm memory.
