What they found out was that the participants were able to apply their interpretation of the rule to other words they were not trained to know only several days after their training. The researchers determined that the participants were not able to show any ability right after training.
In the experiments that they conducted later, wherein they introduced exceptions to the rule that they have set, meaning that –lomb is some kind of tool or gadget, the participants were able to grasp the idea that the newly introduced words were exceptions to the rule only after they have slept overnight.
The findings, according to the researchers neatly fit into the theories that memory has two mechanisms. The theories contend that an individual episode of rapid learning is followed by a slower process for knowledge integration into the long-term memory of an individual. This means that the learning processes depend on separate brain structures optimized for slow and fast learning and suggest that sleep is a critical part of the slower learning process.
There had been many researches showing that the brain continues to process new information even while a person is asleep. It is a period when the process is stronger and resistive to interference thus the information is integrated more fully into the person’s existing knowledge.
The results of the experiments also show better methods for the literacy and teaching of language. The researchers believe that for teachers to be able to convey linguistic principles, they should have a better plan for the introduction of information in such a way that would encourage learning.
The new research results add to the growing list of previous researches indicating that overnight sleep is crucial in learning a language. They suggest that the primary aspects of learning come from instructions from the classroom but the long-term retention of the knowledge is boosted by the proper sleeping behavior of learners.
