Chapter 5 Chapter Summary Flashcards
(40 cards)
Memory is the process involved in…
Retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original information is no longer present
Five different types of memory
Sensory, short-term, episodic, semantic, and procedural
Three structural features of modal model of memory
Sensory memory, short-term memory, and long-term memory
Additional feature of the modal model
Control processes, such as rehearsal and attentional strategies
What methods did Sperling use?
Whole report and partial report
What did Sperling aim to measure?
The capacity and time course of visual sensory memory
Visual sensory memory is also known as
Iconic memory
What is the duration of iconic memory?
Less than 1 second
Auditory sensory memory is also known as
Echoic memory
What is the duration of echoic memory?
About 2-4 seconds
STM is our window on the…
Present
Duration of STM
About 15-20 seconds
Digit span
A measure of the capacity of STM
The capacity of STM according to Miller
5-9 items
What have recent experiments determined about STM capacity?
Closer to 4 items
How can we expand the amount of information held in STM?
Chunking
Chunking
Small units are combined into larger, more meaningful units
Rather than describing STM capacity in terms of number of items, it has been suggested to describe STM in terms of…
Amount of information
Experiment by Alvarez and Cavanagh
Includes stimuli ranging from simple to complex, and findings support the idea that STM should be described in terms of amount of information rather than number of items
Why did Baddeley revise the STM component of the modal model?
To deal with dynamic processes that unfold over time and can’t be explained by a single short-term process
What is the main difference in Baddeley’s revision of the modal model?
Working memory replaces STM
Working memory
A limited-capacity system for storage and manipulation of information in complex tasks
What are the three components of working memory?
The phonological loop, the visuospatial sketchpad, and the central executive
Phonological loop
Holds auditory or verbal information
