What is the dual task technique?
A dual-task paradigm is a procedure in experimental neuropsychology that requires an individual to perform two tasks simultaneously, in order to compare performance with single-task conditions.
What are the main components of Baddeley’s multiple component model of working memory?
The Working Memory model comprises a control system, the central executive, and two storage systems – the visuospatial sketchpad and the phonological loop.
How do dual tasks support the working memory model?
It is more difficult to perform two visual tasks at the same time because they interfere with each other and performance is reduced. The same applies to performing two verbal tasks at the same time. This supports the view that the phonological loop and the sketchpad are separate systems within working memory.
What are the three main components of the Baddeley model?
The three main components of Baddeley’s working memory are the central executive, the phonological loop, and the visuospatial sketchpad.
What is dual-task performance?
Definition. Dual-task performance requires an individual to perform two tasks (i.e., Task A and Task B) simultaneously. Typically this type of performance is contrasted with single-task performance in which the individual only has to perform one task at a time (Task A or B).
What are the factors in determining dual-task performance?
Conclusion: The present study indicated that dual-task performance was related to motor function, balance, and fatigue, whereas gross motor function was the unique determinant of dual-task performance.
What is dual-task performance psychology?
What is Baddeley’s view of working memory?
Baddeley’s model argues that working memory is like a multi-part system, and each system is responsible for a different function. Each part is only able to processes so much and the components of this system, according to Baddeley, function more or less independently of one another.
What did Baddeley and Hitch do?
Baddeley and Hitch (1974) set out to test the hypothesis that the short-term store also functioned as a working memory. They did so by requiring participants to perform reasoning, comprehension or learning tasks at the same time as they were holding in STM between 0 and 8 digits for immediate recall.
Which of the following are components of Baddeley’s working memory theory Select all that apply?
True or False: According to Baddeley’s conceptualization of working memory, there are three components: the phonological loop, visuospatial working memory, and the central executive.
What is Alan Baddeley’s model of working memory?
What are the components of Baddeley’s working memory model quizlet?
An active 3 part memory system that temporarily holds information & consists of: phonological loop, visuospatial working memory, & the central executive.
What are the components of Baddeley’s model of working memory?
Baddeley’s model of working memory. The original model of Baddeley & Hitch was composed of three main components; the central executive which acts as supervisory system and controls the flow of information from and to its slave systems: the phonological loop and the visuo-spatial sketchpad.
Are there any studies on dual task performance?
Two fMRI studies failed to provide support for this view. In tasks involving verbal and face working memory, no new brain area was activated for dual-task performance. Instead, activation increased with dual-task performance but in the same regions active during the performance of each task individually.
What was the fourth component of the Baddeley model?
In 2000 Baddeley added a fourth component to the model, called the ‘episodic buffer’. This component is a third slave system, dedicated to linking information across domains to form integrated units of visual, spatial, and verbal information with time sequencing (or chronological ordering), such as the memory of a story or a movie scene.
Why was the episodic buffer added to the Baddeley model?
Both the slave systems only function as short-term storage centers. In 2000 Baddeley added a third slave system to his model, the episodic buffer. Baddeley & Hitch’s argument for the distinction of two domain-specific slave systems in the older model was derived from experimental findings with dual-task paradigms.
