CH 8 Memory (TERMS) Flashcards
Encoding (1,1)
Translation of the physical stimulation into a cognitive code that is used by the memory system (usually requires conscious attention)
Storage
Maintenance of cognitive codes in memory over time
Retrieval
Recovery of cognitive codes from memory (remembering)
Free-recall task
Report as many items from a list of words in any order (that have been rehearsed aloud)
Serial-position effect
Consistent curve (U-shaped) for list recall
Primacy effect
Items near the beginning of the list recalled better than other items (long-term)
Recency effect
Items near the end of the list are recalled better than other items (short-term)
Sensory memory (+ Encoding, Storage, Retrieval, Forgetting)
Temporary storage of perceptual input for initial memory encoding
- Encoding: Modality specific
- Storage: High capacity, Short duration depending on modality (0.5-4 seconds)
- Retrieval: Attentional
- Forgetting: Decay/interference
Working / Short-term memory (+ Encoding, Storage, Retrieval, Forgetting)
Current processing and manipulation of cognitive codes (conscious processing)
- Encoding: Phonological, visual, spatial storage
- Storage: 5-9 items, less than 30 seconds without rehearsal
- Retrieval: Elaborative rehearsal
- Forgetting: Interference and decay
Long-term memory (+ Encoding, Storage, Retrieval, Forgetting)
- Encoding: Several forms
- Storage: Episodic, Semantic, Procedural; Unlimited capacity, Permanent duration
- Retrieval: Reconstructive
- Forgetting: Retrieval failure
Iconic memory
Vision
Echoic memory
Auditory
Whole report (WR)
Experiment that showed how long memories last in your central memory system (iconic) which we don’t have conscious access to
- People were told to fixate on a point, letters would flash for 15 milliseconds that would be followed by a blank screen. They would then hear a tone
- People could recall 3-4 letters but claimed they remembered more letters than they did
Partial Report (PR)
Part 2 of WR
- Experiment changed so different pitches of tone would indicate which row of letters participants should memorize (remembered 70-76% of material)
- Bad report because participants had already forgotten the letters after hearing the tone
- Concluded information lasted for 0.5 seconds
