| **Central executive** |It is still unclear weather it is a single system or more systems working together. Central executive's functions include **attention** and focusing, **active inhibition** of stimuli, planing and decision-making, sequencing, **updating**, **maintenance** and **integration of information** from phonological loop and visuospatial sketchpad. These functions also include communication with long-term memory and connections to language understanding and production centers. | | | **Central executive** |It is still unclear weather it is a single system or more systems working together.

Just like in Atkinson and Shiffrin model, the ingoing information is first stored in the sensory memory. Sensory information then activates certain elements inside the long-term memory. In his model, Cowan does not address the issue of processing information of different modality like Baddeley. | Just like in Atkinson and Shiffrin model, the ingoing information is first stored in the sensory memory.
