Cognition Flashcards
Storage
Retention of encoded info over time aka keeping it in
Retrieval
Process of getting info out of storage
Sensory memory
Our senses register infinitely more info than we actually process
*holds info from the senses for a max of a few seconds
Iconic memory
Memory of visual stimuli
Echoic memory
Memory of auditory stimuli
Short term memory
Retains 7 +/- bits of info
Retains info for 30 seconds
If we don’t do anything with the info we lose it
(George Miller)
Rehearsal
Conscious repetition of info to maintain info in stm or encode it for storage
Elaborative reversal
Repetition that creates associations (with something we already know) between the new memory and existing memories stored in LTM
Long term memory
Relatively permanent storage
Unlimited capacity
Subdivided into explicit and implicit memory
Explicit memory (declarative memory)
Location: Frontal lobes and hippocampus
(knowledge, facts, personal experiences)
that one consciously knows and can verbalize
Subdivided into semantic and episodic memory
Semantic memory
Memory of general knowledge or objective facts (math, history)
Episodic memory
Memory of personally experienced events (Kukuk getting shot when young)
Implicit memory (non-declarative memory)
Memory of skill and procedures
Learned from experience without having to refer to the experience
Ex. How to shoot a bball
Concepts
Mental representations of related things
Ex. Vertebrates and non vertebrates
Prototypes
The most typical examples of a concept
Schemas
Framework of basic ideas and preconceptions about *pepole *objects *events (Ex. Beak, wings, tail) Based on past experiences
Thalamus
Encodes sensory memory into STM
Hippocampus, frontal and temporal lobes
Establishing of explicit LTM
Amygdala
Processes strong emotionally charged memories
Cerebellum
Processes implicit memory of skills
Retrieval
Process of getting info out of storage; putting together the “pieces” of our memory puzzle
Retrieval cue
A trigger to get info from storage (a hint to resemble that info)
Recognition
Identification of something as familiar (multiple choice/ matching)
Recall
Retrieval of info from LTM without any other info or cues (ex. Fill-in-the-blank/ free response) passive memory
Serial position effect
Stronger recollection of info at the beginning and the end of a list of words
Primacy effect
Stronger recollection of the beginning
Recency effect
Stronger recollection of the end
Context-dependent memory
Memory Recall is stronger if u are in the room you learned the info
Mood-dependent memory
Tendency to recall info based on mood u learned it and if u the same mood when taking the test
State-dependent memory
Tendency to recall info if u in the same internal state in which u encoded the I for (ex. Drunk when learning= better on the test of drunk)
