Overall Cognitive Memory Model
What is the capacity and duration of sensory memory?
Capacity: large Duration: 3 secs or less
The phonological loop is responsible for ______ processing?
Language
What is the span for visual working memory?
About 4 or 5 items
What are DPA trials?
Delayed paired associate trials
What are the states of consciousness for each type of memory?
Sensory: Subconscious
Working/Short term: Active, conscious thinking
Long term: Subconscious
What are the 4 parts under working memory?
Central executive, visuo-spatial sketchpad, episodic buffer, phonological loop
What does the parahippocampal place area do?
Keeps track of locations
The main finding depicted in the DPA trials is related to the bain activity during the ______?
Memory delay
What is the primary goal of elaborative rehearsal versus maintenance?
Keep in STM longer versus consolidate to LTM
What are the 3 parts under LTM?
Visual semantics, episodic LTM, Language
All _____ play a role in vision. Half of ______ in the _____ are visual
lobes; neurons; cortex
What is articulatory suppression?
Making a participant perform a distracting verbal task during a retention period.
What is encoding? What is consolidation? What is retrieval?
Encoding: Sensory - STM
Consolidation: STM-LTM
Retrieval: LTM-STM
What is the main difference with the contemporary view?
No STM; just conscious awareness. There is only the ability to call up LTM's into one's conscious awareness.
What does the fusiform face area do?
Keeps track of faces
What is the main idea of the trial studies?
STM involves the temporary activation of the LTM extending to perceptual features
What are the capacities/durations of STM and LTM?
STM: Capacity is 7+-2, duration is 2 mins or less
LTM: Capacity is gigantic, lasts a lifetime
What types of information does visual semantics, episodic LTM and language fall under?
Visual semantics: perceptual representation system (implicit)
Episodic LTM: episodic and semantic system (explicit)
Language: episodic and semantic system (explicit)
What is a DMS trial?
Delayed matching-to-sample trial; participants view two images separated by a time delay and have to decide if they were identical or not
What were the results of the main study?
When a house was shown, the PPA activated above base level and during the delay period, the activation would switch to the FFA before the face was even shown and vice versa. The stimulus was still active during the time delay, showing that it was still activating the ventral streams.
