When extensive, the person has attempted to make the to-be-remembered information meaningful and has engaged in detailed processing. This means that the individual tries to connect the new information with existing knowledge, making it more relevant and easier to recall. Extensive processing involves elaboration, visualization, self-referencing, and organizing the information, which leads to better encoding and long-term retention in memory. This detailed semantic processing is considered "deep" processing and generally results in stronger and more durable memory traces compared to shallow processing, which focuses on superficial features.
