Atkinson-Shiffrin Model
A model for describing memory in which there are three distinguishable kinds of memory (sensory, short term, long term) through which info passes in a sequential way as it is processed.
Executes memory rehearsal.
Central Executive
Suppresses irrelevant information from being processed
Central Executive
Which working memory component would be most active if you are trying to ignore a distracting conversation in the library while studying for your next exam?
Central Executive
Component where information from other working memory parts is combined.
Episodic Buffer
What advantage does working memory present in our lives?
It allows us to process multiple sources of information within a short period of time.
What does the episodic buffer in Baddeley's working memory model do?
It briefly holds material coming from the phonological loop, the visuospatial sketchpad, and long-term memory.
Which of the following is a true statement about the neuroscience research on the central executive?
It is primarily controlled by portions of the frontal lobe.
Semantics
Meaning of words and sentences
Active during subvocalization.
Phonological Loop
Part of this component may be located in the left temporal lobe.
Phonological Loop
While studying the vocabulary in your cognitive psychology class, you find it harder and harder to learn and remember new terms encounter. This could be an example of what type of memory problem?
Proactive interference
information-processing approach
The approach to psychology, developed beginning in the 1950s, in which the mind is described as processing information through a sequence of stages.
According to the research, people with ADHD are especially likely to have difficulty with which of the following components of working memory?
The central executive
What is the serial position effect in memory research?
The finding that people are best at remembering the first few and last few items on a list.
In Baddeley's working memory model, which component would you expect to be most active when auditory task like trying to remember the lines to a play?
The phonological loop
While building some furniture, you try to remember each necessary step in the instructions. You can easily remember the first three steps but then struggle to remember what to do next.
The primacy effect.
How does the earlier view of short-term memory differ from the current view of working memory?
Unlike short-term memory, working memory is continuously manipulating information, not just storing it.
Active during mental imagery.
