Q. What is Working Memory?
Working Memory: It has often been suggested that memory does not always work in three stage sequence and the model of memory system comprising of sensory, short-term and long-term memory is too simplistic.
Therefore another concept has been introduced by Alan Baddeley i.e. Working Memory. It is a system that temporarily holds information as people perform cognitive tasks. It is a kind of mental workbench on which information in manipulated and assembled to help us comprehend language, make decisions and solve problems. It is an active memory system.
Retrieval: This is the process of gaining access to stored, coded information when it is needed.
Neurochemistry of Memory: Memory is the result of certain neural mechanism and biochemical responses in the brain following sensory input. First the neural mechanism will be discussed followed with the role of various neurotransmitters.
