In the three-layer model of information processing, which are the components?

• A. Sensory register, long-term memory, and executive functions.
• B. Working memory, short-term memory, and procedural memory.
• C. Perceptual store, episodic memory, and recall.
• D. Sensory memory, semantic memory, and cognitive control.

Answer: (A)

Information moves through three stages: a sensory register that captures incoming stimuli, a working memory system where attention and mental operations happen under the guidance of executive functions, and a long-term memory store for enduring retention. The best answer lists those components—sensory register, long-term memory, and executive functions—which together describe the flow from initial perception, through controlled processing, to durable storage. Executive functions act as the control processes within working memory—planning, updating, shifting, and inhibiting—that organize and encode information for transfer into long-term memory. That alignment with how processing unfolds makes this option the most accurate representation of the three-layer model. The other choices mix different memory types or focus on contents rather than the processing stages, so they don’t fit as the structural layers.
