-
Memory
the persistence of learning over time through the storage and retrieval of information
-
Encoding
the processing of information in the memory system, getting information into our brain
-
Storage
the retention of encoded information over time, retaining information
-
Retrieval
the process of getting information out of memory storage, getting information out of the head
-
Connectionism
modern model of memory which views memory as emerging from 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
-
Parallel Processing
the processing of many aspects of a problem simultaneously; the brain’s natural mode of information processing for many functions. Contrasts with the step-by-step serial processing of most computer and of conscious problem solving
-
Rehearsal
the conscious repetition of information, either yo maintain it in consciousness or to encode it for storage
-
Spacing Effect
the tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice
-
Testing Effect
testing is good at helping you learn, not just assessing
-
Serial-Position Effect
our tendency to recall best the last and first items in a list
-
Recency Effect
recalling more recent events better
-
Primacy Effect
remembering the first in a list better
-
Visual Encoding
the encoding of picture images
-
Acoustic Encoding
the encoding of sound, especially the sound of words
-
Semantic Encoding
the encoding of meaning, including the meaning of words
-
Self-reference effect
remembering descriptions given about yourself
-
Imagery
mental pictures; a powerful aid to effortful processing, especially when combined with semantic encoding
-
Rosy Retrospection
forgetting the non-important parts and remembering the semantic/strong feeling parts of a memory
-
Mnemonic
memory aids, especially those techniques that use vivid imagery and organizational devices
-
Peg-Word System
associating two words together
-
Chunking
organizing items into familiar, manageable units; often occurs automatically
-
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 to 4 seconds
-
Long-Term Potentiation
an increase in a synapse’s firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory.
-
CREB
a neural protein that can switch genes off or on
-
Glutamate
a neurotransmitter that enhances synaptic communication
-
Deja vu
the eerie sense that “I’ve experienced this before.” Cues from the current situation may subconsciously trigger retrieval of an earlier experience or parallel processing is not in sync
-
State-Dependent Memory
When experiencing a situation associated with a certain emotion, we are more likely to remember the memory when feeling the same emotion
-
Mood-Congruent
the tendency to recall experiences that are consistent with one’s current good or bad mood
-
Absent-mindedness
inattention to details leads to encoding failure
-
Transience
storage decay over time
-
Blocking
inaccessibility of stored information (it’s on the tip of my tongue)
-
Misattribution
confusing the source of information (remembering a dream as real life)
-
Suggestibility
the lingering effects of misinformation (an outside source creates false memories)
-
Bias
belief colored recollections/ viewing events by the way you feel now
-
Persistence
unwanted memories
-
Proactive Interference
the disruptive effect of prior learning on the recall of new information
-
Retroactive Interference
the disruptive effect of new learning on the recall of old information
-
Repression
in psychoanalytic theory (Freud), the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings and memories
-
Misinformation Effect
incorporating misleading information into one;s memory of an event
-
Imagination Inflation
imagining nonexistent actions and events that create false memories
-
Source Amnesia
attributing to the wrong source an event we have experienced, heard about, read about, or imagined. Source amnesia, along with the misinformation effect is at the heart of many false memories. We retain the memory of the event, but not the context in which we required it.
