Various mental puzzles and memory tasks can seem difficult until a heuristic or generalizable problem-solving technique is discovered or invented. A mnemonic (memory device) can help learners remember information. A heuristic or mnemonic can make an underlying pattern discernable or make a task more meaningful by relating it to prior knowledge. The four experiments in this activity are not so much analogies as they are direct probes into and models of the processes involved in human memory capacity associated with words and numbers.
