Short-Term Memory: The Working Memory Model

786 Words 4 Pages
Memory is a fundamental factor in psychology that has been found difficult to explain and measure as it is not tangible or measurable. Three main memory models have been devised which attempt to explain the different aspects of memory, one of which is the Working Memory Model. This model is used to explain short-term memory and its components and is constantly working to encode information we receive and pass it to our Long-term memory. We will be discussing how we use the working memory and its components in an everyday activity such as learning the moves in kickboxing to show how this aspect of memory works to support us.

Baddeley and Hitch (1974) devised the Working Memory Model (WM) which explained the Short-term memory (STM) as being made up of different storage units. The WM defined STM as

Two of these units allow for sensory encoding of Verbal and Visio-spatial information, these are called the phonological loop and the Visio sketchpad. The central executive performs many roles from retrieval of information in each sensory component, further processing and encoding of the information to ensure understanding, preparing information for transfer to the third slave unit; the episodic buffer. The role of the central executive is complex and varied, but our understanding is limited due to lack of research (Lieberman, 2004). The episodic buffer, which, was added later due to criticism (Lieberman, 2004) ) is described as a temporary storage space used to integrate information to and from the central executive from the LTM.
To put this into perspective, imagine you have just joined a kickboxing class, and the trainer asks you to perform a ‘jab cross’ move. You hear the words and your phonological loop encodes them, you understand them, but you don’t know what that particular move involves. The
