Cognitive science and instructional design principles consistently demonstrate that human memory systems operate under capacity-limited working memory and processing constraints.

The analysis

The retrieved literature extensively documents human cognitive architecture, specifically highlighting working memory capacity limits, information processing constraints, and cognitive load theory. While long-term memory has vast capacity, working memory limits and processing constraints impose a practical bottleneck on active knowledge acquisition and learning at any given time, directly supporting the claim.
