In their paper‚ Baddeley and Hitch (1974) proposed a working memory model comprised of three basic components. The central executive was the system that dealt with decision making‚ reasoning and coordination of the other two subsidiary systems. The two subsidiary systems that were initially proposed included the visuospatial sketchpad and articulatory loop. The visuospatial sketchpad was thought to be involved in the transitory storage and manipulation of visual and spatial information‚ while a similar

Evaluate the Working Memory Introduction Human memory is a complex cognitive structure‚ which can be defined in many ways. One would argue that memory is 1.) The mental function of retaining information about stimuli‚ event‚ images‚ ideas‚ etc. after the original stimuli is no longer present. 2.) The hypothesized storage system in the mind that holds this information is so retained. A clear distinction is made between different types of memory systems and can be divided into subclasses. The

The Working memory model‚ proposed by Baddeley and Hitch in 1974 has great significance as it developed the multi-store model of Atkinson and Shiffrin which proposed that information was stored in specific locations; the short-term store‚ long-term store and the sensory store‚ along with suggesting the new idea of central executive and its slave systems. The Central executive is the element which is involved in a higher mental process such as decision making‚ as it can co-ordinate performances
Premium Working memory Short-term memory Memory
The working model of memory is a model of short term memory which was developed from experimentation and observation by Baddeley and Hitch in 1974. They developed this as they didn’tt believe that short-term memory was as simple as being only one store. The WMM consists of 3 main stores‚ the central executive‚ the phonological loop and visuo-spatial sketchpad. The central executive can store information for a brief period of time and has limited capacity‚ it is needed to perform a number of tasks

Outline and evaluate the working memory model (12 marks) Baddeley and Hitch proposed that memory has 4 components. The central executive‚ phonological loop‚ visuospatial sketchpad and the episodic buffer. The central executive decides how to share out and direct attention to incoming information. The phonological loop can be thought of as a maintenance rehearsal mechanism for retaining verbal information. It is sub-divided into two other components‚ the phonological store (inner ear)‚ which holds

Outline and Evaluate the Working Memory Model The working memory model is a theory for how short-term memory works‚ and an expansion of the views expressed in the MSM theory. Baddeley and Hitch in 1974 felt that STM was not just one store but a collection of different stores. These concepts lead them to form a model which consists of three slave systems; the central executive‚ the phonological loop and the visuo-spatial sketchpad. They used the phrase ‘working memory’ to refer to the division of

the researchers Baddeley and Hitch argued that the picture of short-term memory (STM) provided by the Multi-Store Model was far too simple. Following the Multi-Store Model‚ it is believed that STM holds limited amounts of information for short periods of time with relatively little processing‚ it is believed to be a unitary store. This means that due to its single store it has no subsystems‚ unlike the Working Memory Model which has many subsystems. This proves that the Working Memory is not a unitary

Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called the working memory model. The working memory model consists of four components. The central executive which controls and co-ordinates the operation of two subsystems‚ the phonological loop and the visuo-spatial sketchpad. The central executive controls attention and coordinates the actions of the other components‚ it can briefly store information‚ but has a limited capacity. The phonological loop consists

The Working Memory Model (WMM) is a theory by Baddeley and Hitch in 1974. The theory replaces the idea that there is a single Short Term Memory (STM) from Atkinson and Shiffrin (1968)‚ it suggests that the STM is a flexible multi-component system. The WMM suggests that the STM is controlled by the Central Executive (CE) which controls attention‚ planning and synthesising information. The Central Executive is a flexible system which means it can process audio‚ visual and sound information‚ it also
