Memory - WMM Flashcards
Name a study that supports the Central executive
HUNT - investigated evidence do limited capacity of the CE
[both were competing for the same limited capacity available.]
Pts performed a psychomotor task - gliding a lever between two posts with only the use of thumb and index finger and at the same time completed an intelligence test consisting of spatial patterns.
✖️repeated measures/order effects/ pats could be tired/ lacks validity
✖️display demand characteristics/les valid
What is the role of the phonological loop?
Phonological store: hold words for 1.5-2 seconds
Articulately control processes: rehearses information from the phonological store.
Name a study supporting the phonological loop.
BADDELEY ET AL - recall long and short words; recalled short words more than long.
Found that the phonological loop can hold items that can be said in 2 seconds. Known as the word length effect
What is the role of the Visio spatial sketchpad
It has limited capacity and is a temporary memory system for holding visual and/or spatial information (shapes and colours)
Name a study supporting the Visio spatial sketchpad
TODD AND MAROIS - used brain imaging
Found more activity in the left half of the brain for visual task and more activity in the right side of the brain for spatial.
What is the role of the episodic buffer
It’s responsible for integrating and manipulating material in working memory
Name a study supporting the episodic buffer
ALKHALIFA - numbers on a screen, either as a sequence or in a parallel fashion and was required to answer a number of problem solving questions.
Found pts given numbers in a sequence got more problem solving questions right than those in a parallel fashion.
What is the role of the central executive?
It decides which systems are needed and monitors and coordinates the operations of these slave systems.
It directs attention and gives priority to particular tasks.
Modality free and has limited capacity.
