Baddeley And Hitch Model Of Working Memory

448 Words2 Pages
In 1974, Baddeley and Hitch proposed a new model of working memory to expound upon the existing model of short term memory. Their initial framework was modular, with the temporary storage system components separate from long term memory. Recent research explores, both theoretically and experimentally, the connection of long-term language production knowledge on verbal working memory, specifically with immediate serial recall tasks. In section 2, I will first briefly introduce relevant aspects of Baddeley and Hitch’s influential model and also provide an overview of recent research articles exploring the connection of language production to verbal working memory. In section 3, I will discuss the details of the experiment for this proposal. Lastly,…show more content…
Baddeley (2012) discusses this model and how it has evolved over the years. He introduces the basic components of their initial framework, which consist of the central executive that controlled information flow to and from two separate temporary storage systems: the phonological loop and the visuo-spatial sketchpad. He explains that the phonological loop refers to a temporary store of verbal information that can be maintained through rehearsal. He found an improved memory span for words that produce a sentence over unrelated words indicating that the phonological loop interacts with outside systems. To account for this interaction, he added another component to his model that interacts with long term memory, which he called the episodic…show more content…
She argues that the divide in research between the language production and temporary verbal memory stems from serial recall tasks because recalling random words from a list is seen by researchers as separate from the long term knowledge needed to order words in a sentence, which she views as an immediate verbal memory task. To support her theory that there is a connection, she discusses several effects that occur in immediate serial recall tasks that also occur in speaking, such as the similarity effect, primacy effect, and list-length effect. This idea of behavioral similarity is also argued in another article. Acheson and MacDonald (2009) argue against verbal working memory being an isolated system and that the maintenance aspect of the phonological loop can be attributed to the serial ordering process of phonological encoding, which they define as “the process by which a word is specified as a sequence of phonemes for the purposes of articulation” (p.
