Final answer:
To remember information more effectively, the technique of elaborative rehearsal should be used, which involves deep processing and linking new information to existing knowledge and memories.
Step-by-step explanation:
The idea that suggests that to remember a piece of information better, you should think about it more deeply and link it to other information is called elaborative rehearsal. This technique is based on the levels of processing model proposed by Craik and Lockhart. By engaging in elaborative rehearsal, you link new information to existing knowledge, thus embedding it more firmly in your memory. Examples include visualizing a hippocampus as a hippopotamus to remember its association with memory, or linking a new acquaintance's phone area code with a relative's area code to better recall it. Implementing this technique, along with practices like distributed practice and using mnemonic devices, enhances memory consolidation and retrieval.
