In the information processing model, which component holds incoming sensory information briefly before processing?

• A. Sensory register.
• B. Long-term memory.
• C. Executive functions.
• D. Working memory.

Answer: (A)

Incoming sensory information is briefly stored in the sensory register. This stage acts as a temporary buffer right after perception, giving the brain a moment to decide what to attend to next. The storage is very brief—visual input can stay as iconic memory for a fraction of a second, while auditory input can linger a bit longer as echoic memory—long enough for attention to shift into further processing. From there, attended information moves into working memory for active processing and manipulation, and, with enough effort, into long-term memory for lasting storage. Long-term memory holds information over extended periods, not the immediate, fleeting reserve this stage provides. Working memory is the space where ongoing cognitive work happens, and executive functions govern control processes like attention and planning rather than serving as a storage spot.
