Memory_Flashcards_Updated
What type of encoding is used in the short-term memory (STM)?
Acoustic encoding, as shown by Baddeley’s study.
What type of encoding is used in long-term memory (LTM)?
Semantic encoding, according to Baddeley’s study.
What is the capacity of STM according to Jacobs and Miller?
Jacobs found it to be about 7 +/- 2 items, supporting Miller’s magic number 7.
How long does STM last according to Peterson and Peterson?
About 18–30 seconds without rehearsal.
How long can LTM last according to Bahrick’s study?
Up to a lifetime; people could recall classmates after 48 years.
What are the three components of the Multi-Store Model of memory?
Sensory register, short-term memory, long-term memory.
What is a strength of the MSM?
Supported by studies like Baddeley and Peterson & Peterson showing different stores.
What is a limitation of the MSM?
Oversimplifies memory; KF study shows STM is not unitary.
What are the three types of long-term memory?
Episodic, semantic, and procedural.
What type of LTM involves remembering personal experiences?
Episodic memory.
What type of LTM involves knowledge of facts?
Semantic memory.
What type of LTM involves knowing how to do things?
Procedural memory.
What evidence supports different types of LTM?
Tulving’s brain scans show different areas active for episodic and semantic memory.
What are the four components of the Working Memory Model?
Central executive, phonological loop, visuo-spatial sketchpad, episodic buffer.
What is the role of the central executive?
To direct attention and allocate resources to tasks.
What does the phonological loop process?
Auditory information and preserves order of information.
What does the visuo-spatial sketchpad do?
Processes visual and spatial information.
What is the episodic buffer?
Integrates information from other stores and links to LTM.
What is a strength of the WMM?
Supported by dual-task studies showing separate systems.
What is a limitation of the WMM?
The central executive is vague and not well explained.
What is proactive interference?
Old information interferes with the new.
What is retroactive interference?
New information interferes with the old.
What study supports interference theory?
McGeoch & McDonald – similar material leads to more forgetting.
What is retrieval failure due to absence of cues?
Inability to access memory because of missing external or internal cues.
