Final answer:
Short-term memory (STM) in the Atkinson-Shiffrin model corresponds to what is currently recognized as working memory, serving as a temporary storage system for processing information.
Step-by-step explanation:
The component of the Atkinson-Shiffrin model that is most similar to what is nowadays referred to as working memory is c) Short-term memory (STM). The Atkinson-Shiffrin model suggests that memory processes operate in a linear fashion, with information passing through sensory memory, then to short-term memory, and eventually transferred to long-term memory if effectively rehearsed.Short-term memory is where information from our sensory memory is processed and temporarily stored. Sensory memory is considered a very brief storage of sensory events, whereas long-term memory is a more permanent storage system. However, it is the short-term memory that serves a similar function to working memory, acting as a temporary holding area for information that is being processed. Our current understanding of working memory, substantially influenced by Baddeley and Hitch's model, describes it as more complex, involving a central executive that controls information flow and connects to various subsystems like the phonological loop, episodic buffer, and visuospatial sketchpad.In conclusion, the short-term memory corresponds to working memory in the Atkinson-Shiffrin model. While short-term memory was originally depicted as a single storage unit, it has since been elaborated upon by later models and is now understood to have a more complex structure and function akin to what we consider working memory.
