A server repeats a six-digit table number silently while walking across a restaurant. When another customer asks a question, the server loses the number before entering it. Which memory system was most directly overloaded?
- AImplicit memory, because the number was stored as an unconscious skill.
- BLong-term potentiation, because synapses permanently stopped changing.
- CWorking memory: active maintenance was interrupted.correct
- DFlashbulb memory, because the event was emotionally shocking and durable.
Why C is correct
The interruption disrupts temporary active maintenance.
working memory is the mechanism that makes "A server repeats a six-digit table number silently while walking across a restaurant." coherent. The credited option, "Working memory, because brief active maintenance was interrupted by a competing task", is supported because The server was actively maintaining information briefly, which fits working memory. "Long-term potentiation, because synapses permanently stopped changing" is a real-looking alternative, but Long-term potentiation concerns neural strengthening, not losing a just-repeated number; "Flashbulb memory, because the event was emotionally shocking and durable" also fails because The situation is ordinary and temporary, not a vivid durable event. The aim is to connect the concrete evidence to the psychological mechanism, then reject choices that shift the process, time frame, or research logic away from the scenario pattern.
