BADDELEY Medical Research Council‚ Applied Psychology Unit AND NElL THOMSONAND MARY BUCHANAN University of Stifling‚ Scotland A number of experiments explored the hypothesis that immediate memory span is not constant‚ but varies with the length of the words to be recalled. Results showed: (1) Memory span is inverselyrelated to word length across a wide range of materials;

Effects of Background Music on Phonological Short-term Memory In this research article‚ written by Pierre Salame and Alan Baddeley‚ a series of tests were conducted to observe if a person’s short term memory was affected by listening to instrumental music versus vocal music. It is noted that immediate memory is verbally disrupted by concurrent- occurring simultaneously- speech. In Pierre’s experiment‚ he tested subjects to recall a sequence of nine digits that were visually presented. In separate

The nature of memory: STM‚ LTM and Duration Duration of STM One of the key differences between the concepts of STM and LTM is duration. “Duration” refers to how long a memory lasts before it is no longer available. Short term memories don’t last very long. An example of STM in action would be trying to remember a seven-digit phone number that you have just been given. This is maintained in the short-term memory by REPETITION until the number is dialled‚ and then fades once the conversation

*Evaluate a model or a theory of one cognitive process (e.g. memory‚ perception‚ language)‚ with reference to research studies (22)* The Multi Store Model of Memory (also known as the Atkinson and Shiffrin Model of Memory) is a simplified cognitive model of the memorial structure of the human mind. It was first proposed by Richards Atkinson and Shiffrin‚ in 1968. It was one of the first models of memory to show a clear and systematic approach to the store and retrieval of memory‚ and although now

Short Term Memory and Long Term Memory Short term memory (STM) is stored in the brain for approximately 3- 18 seconds‚ whereas long term memories (LTM) can be stored in the brain from up to a few minutes to a lifetime. STM and LTM have different encoding processes. STM is encoded into the brain mainly by sound (acoustic)‚ the way LTM is encoded into the brain in terms of the word or situations meaning rather than sound (semantically). The capacity of LTM seems unlimited‚ though research has shown

ATTENTION: -Lab Stroop Effect’s Theory: During the experiment‚ it was more difficult to indicate the color ink that the word was shown in when the word itself indicated a non-corresponding color. This is the Stroop Effect: the finding that people identify the color of a word more slowly when color and word are incongruent (for example‚ the word BLUE printed in a red color) than when color and word are congruent (for example the word BLUE printed in blue). But why is identifying the color of

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

Memory can be defined as the process of acquiring information through encoding by changing it to a usable form‚ storage for later use and retrieval by bringing stored memories into conscious awareness state (Sternberg‚ 1999). The flow of information from the sensory input into the short term working memory (STM) and the long term permanent memory (LTM) is based on the subject’s control (Atkinson & Shiffrin). The subject controls the flow of information with the aid of control processes that act within
