Term
Encoding
Definition
Refers to getting information into the system by translating it into a neural code that your brain processes.
Term
Retrieval
Definition
A process where you can pull information out of storage when you want to use it
Term
Sensory Memory
Definition
Holds incoming sensory information just long enough for it to be recognized
Term
Short term / Working Memory
Definition
Holds the information that we are conscious of at any given time. Constantly processes codes and works on information.
Term
Memory Codes
Definition
Visual, phonological, semantic, or motor encoding that stores information so it can be retained in short-term and long-term memory.
Term
Iconic Store / Iconic Memory
Definition
Sensory storage mechanism in which a purely visual representation of a stimulus array is held as a trace memory
Term
Echoic store
Definition
Sensory storage mechanism in which a purely audible representation of a stimulus array is held as a trace memory
Term
Chunking
Definition
Combining individual items into larger units of meaning. This can greatly aid recall. Example: chunking all the planets into a sentence, "So My Very Eloquent Mother Just Served Us Noodle Pie."
Term
Maintenance Rehearsal
Definition
The simple repetition of information in an attempt to remember it
Term
Elaborative Rehearsal
Definition
Focusing on the meaning of information or relating it to other things you already know in attempt to remember it. (Most effective way to transfer information to long-term memory.)
Term
Serial Position Effect
Definition
Recall is influenced by a word's position in a series of items. Two components: Primacy effect, easy to remember early information. Recency effect, easy to remember recent information.
Term
Levels of Processing
Definition
Listed shallowest to deepest.
Visual or structural: processing only structure properties.
Phonological: processing the sound.
Semantic: processing the meaning.
Term
Mnemonics
Definition
The art of improving memory. Refers to the greek god, Mnemosyne.
Term
Dual Coding Theory
Definition
The theory that, if we encode information by using both verbal and imagery codes, the chances improve that at least one of the two codes will be available later to support recall.
Term
Schema
Definition
A mental framework, an organized pattern of thought about some aspects of the world, such as a class of people, events, situations, or objects.
Term
Associative Network
Definition
A massive network of associated ideas and concepts
Term
Neural Network
Definition
Each concept stored within the memory is represented by a particular pattern or set of nodes that becomes activated simultaneously.
Term
Declarative Memory
Definition
Involves factual knowledge. Demonstrated by reciting facts or information. Includes two subcategories: knowledge pertaining to personal experience (episodic), and knowledge of general facts and language (semantic).
Term
Episodic Memory
Definition
Our store of factual knowledge concerning personal experiences, like when and where and what happened at different times of our lives. Example, I remember I went hiking last week
Term
Semantic Memory
Definition
Represents general factual knowledge about the world and language, including memory for words and concepts.
Term
Procedural Memory
Definition
Memory that is reflected in skills and actions. The type of memory associated with classical conditioning. This kind of memory is non-declaritive.
Term
Explicit Memory
Definition
Involves conscious or intentional memory retrieval, as when you consciously recall or recognize something.
Term
Implicit Memory
Definition
Occurs when memory influences our behaviour without conscious awareness.
Term
Retrieval Cue
Definition
Any stimulus, whether internal or external, that stimulates the activation of information stored in long term memory
Term
Flashbulb Memories
Definition
Recollections that seem so vivid, so clear, that we can picture them as if they were a snapshot of a moment in time
Term
Encoding Specificity Principal
Definition
States that memory is enhanced when conditions present during retrieval match those that were present during encoding. Includes context-dependent memory and state-dependent memory.
Term
Context-Dependant Memory
Definition
The idea that it is typically easier to remember something in the same environment in which it was acquired.
Term
State-Dependent Memory
Definition
Proposes that our ability to retrieve information is greater when out internal state at the time of retrieval matches our original state during learning.
Term
Mood Congruent Recall
Definition
We tend to recall information or events that are congruent (in agreement) with our current mood
Term
Decay Theory
Definition
Proposes that with time and disuse the physical memory trace in the nervous system fades away. This concept, idea, theory, is still under debate by psychologists.
Term
Proactive Interference
Definition
Occurs when material learned in the past interferes with the recall of newer material.
Term
Retroactive Interference
Definition
Occurs when newly acquired information interferes with the ability to recall information learned in the past.
Term
Repression
Definition
The idea that one's sub-conscience may protect oneself by blocking the recall of anxiety-arousing memories.
Term
Retrograde Amnesia
Definition
Represents memory loss for events that occurred prior to the onset of amnesia
Term
Anterograde Amnesia
Definition
Refers to the memory loss for events that occur after the initial onset of amnesia.
Term
Dementia
Definition
Refers to impaired memory and other cognitive deficits that accompany brain degeneration and interfere with normal functioning.
Term
Alzheimer's Disease (AD)
Definition
A progressive brain disorder that is the most common cause of dementia among adults over the age of 65
Term
Prospective Memory
Definition
Concerns remembering to perform an activity in the future
Term
Infantile Amnesia
Definition
The inability to remember the first few years of one's life.
Term
Misinformation Effect
Definition
The distortion of a memory by misleading post-event information
Term
Source Confusion
Definition
Our tendency to recall something or recognize it as familiar, but to forget where we encountered it
Term
Memory Consolidation
Definition
The creation and binding together of neural codes that allow information to be transferred from short-term to long-term memory
Term
Long-Term Potentiation (LTP)
Definition
An encoding increase in synaptic strength that occurs after a neural circuit is rapidly stimulated.
