Cognition Flashcards
Information Processing Model
(Of Memory) encoding, storage, and retrieval.
Encoding
The process of putting info into the memory system.
Storage
The retention of encoded info over time.
Retrieval
The process of getting info out of memory storage.
Shallow Processing
Structural encoding emphasizes structure of incoming sensory info.
Deep processing
Semantic encoding involves forming an association or attaching meaning to a sensory impression and results in longer lasting memories.
Self reference effect/encoding
Processing info deemed important or relevant more deeply, making it easier to recall.
Sensory Memory
Memory system that holds external events from senses for up to a few secs.
Visual encoding
The encoding of pics.
Iconic memory
A momentary sensory memory of a visual stimuli.
Acoustic Encoding
The encoding of sound. Especially words.
Echoic Memory
A momentary sensory memory of auditory stimuli.
Automatic Processing
Unconscious encoding of info about space, time, and frequency that occurs without interfering with our thinking about other things.
Parallel Processing
A natural mode of info processing that involves several info streams simultaneously.
Effortful Processing
Encoding that requires our attention and effort.
Feature Extraction
(Pattern Recognition) finding a match for new raw info in sensory storage by actively searching through long term memory.
Short term memory
(Working memory) 20 secs before its forgotten. Usually for 7 items.
Maintenance Rehearsal
Repetition that keeps info in STM about 20 secs.
Elaborative Rehearsal
Repetition that creates associations between the new memory and existing memories stored in LTM.
Method of Loci
Uses visualization with familiar objects on a path to recall info in a list.
Peg word system
Uses association of terms to be remembered with a memorized scheme.
Explicit Memory
Memory of facts and experiences that one consciously knows and can verbalize.
Semantic Memory
Memory of general knowledge and objective facts. Part of explicit memory.
Episodic memory
Memory of personally experienced events. Part of explicit memory.
Implicit memory
Retention without conscious recollection of learning the skills and dispositions.
Procedural Memory
Memories of perceptual, motor, and cognitive skills. Part of implicit memory.
Hierarchies
Systems in which concepts are arranged from more general to more specific classes.
Concepts
Mental representations of related things.
Prototypes
The most typical examples of a concept.
Semantic Networks
More irregular and distorted systems than strict hierarchies, with multiple links from one concept to another.
Script
A scheme for an event.
Connectionism
Theory that memory is stored throughout the brain in connections between neurons, many of which can work together to process a single memory.
Artificial Intelligence
A field of study in which computer programs are designed to simulate human cognitive abilities such as: reasoning, learning, and understanding language.
Parallel processing model
Clusters of neurons that are interconnected and process info simultaneously, automatically, and without our awareness.
