What is the first phase of memory processing according to the Two-Store Model?

The first phase of memory processing according to the Two-Store Model is the Sensory Register. This stage involves the initial intake of information through our senses, where sensory stimuli are briefly held in their raw form. The Sensory Register serves as a buffer for stimuli received through sight, sound, touch, taste, and smell, for a very short duration—typically only lasting a fraction of a second to a few seconds.

In this phase, information is not yet processed or organized; it is merely retained long enough for further processing to occur. If the information is attended to, it can then move into the Working Memory, where it is actively manipulated and used. Only after further processing might information be encoded into Long-Term Memory for more permanent storage. Thus, the Sensory Register is fundamental in laying the groundwork for the subsequent stages of memory, making it the correct choice in this context.
