The phonological loop processes sounds and is responsible for speech based information. This includes sounds that are processed in one’s mind. For example, the phonological loop is used in learning new vocabulary, problem-solving, math problems, and remembering instructions. In all these tasks, sounds are being processed through the phonological loop. The two components of the phonological loop are the phonological store and the articulatory control process. The phonological store holds the information for 1.5-2 seconds. The articulatory control process refreshes the information in the phonological store. It also converts written material into phonological code so that it can be registered by the phonological store
