The major aspect of human cognitive architecture is the size of long-term memory. , ability to learn and solve problems) stem from quantitative differences in long-term memory (Sweller, 2003; 2004). As mentioned previously, if no knowledge structures are available in long-term memory to organize new information, learners try random combinations followed by the test of their effectiveness. As the number of elements increases, the number of possible combinations increases exponentially (a combinatorial explosion).
Higher-level cognitive processes are used to direct and sequence lower-level processes. Long-term memory structures and levels of their acquisition define the characteristics of working memory: its content, capacity, and duration. Accordingly, the characteristics of learning and performance alter significantly with the development of learners’ expertise in a specific domain. In the absence of relevant prior knowledge, novices are dealing with many new elements of information that may easily overload their working memories.
On the other hand, mechanical apprentices may see only some individual familiar elements without understanding how they work together. Detailed multimedia instructions (for example, an animation of the engine operation with appropriately placed and synchronized narrated auditory explanations) would certainly help the novice learners to understand the operation of the engine. However, when the same detailed instructions are presented to the experienced technicians, they may find them unnecessary and frustrating, especially if they have to attend to the instructional details.
