forgetting in short term memory Flashcards
brown-Peterson paradigm
The task aims to test the number of objects that can be held in working memory
but as the time passes the information are just gone
keppel and underwood
-interference theory -
Displacement of information from memory due to competing information
+proactive interference: reduction in memory performance for recently learned information resulting from the prior learning of related materials
—– learn task A and task B BUT failing in recalling the task B
+retroactive interference: reduce the memory performance for the task learned in the first resulting from the recently learned information
—— learn task A and task B BUT failing to recall the task A
spontaneous recovery
by the time passes the recall for the first list increases
characteristics of the short-term memory
Ø Limited capacity (7 ± 2 items/chunks)
Ø Short duration
Ø Primarily verbal in nature
Ø Maintains information through rehearsal
Ø Forgetting- decay vs. interference
Ø Codes information acoustically
working memory
the small amount of information that can be held in mind and used in the execution of cognitive tasks
central executive
The central executive system is considered to be primarily responsible for coordinating activity within the cognitive system,
-episodic buffer
-phonological buffer
-Visuospatial Sketchpad
episodic buffer
Ø Unifies the different codes from the subsystems and combines them into a single representation
Ø WM’s tie with Long Term Memory
phonological buffer
a short-term storage, responsible for the short-term maintenance of phonological units until their articulation, as well as for phonological and morphological composition.
visuospatial sketchpad
our ability temporarily to hold visual and spatial information
working memory findings
Ø Phonological similarity effect
Ø Articulatory Suppression
Ø Word Length Effect
phonological similarity effect
poor serial recall performance for lists composed of similar‐sounding words compared to lists of dissimilar‐sounding items.
articulatory suppression
a method used to inhibit subvocal rehearsal of items in a memory test or experiment by requiring the participant to perform a distracting verbal task, such as counting or naming, during the retention period.
word length effect
refers to the fact that lists of words that take more time to articulate—longer words—are more poorly remembered than words that take less time to articulate
