Information learnt through mnemonics makes use of a form of deep processing, elaborative encoding. This elaborative processing can be autobiographical or semantic. Another type of rehearsal is elaborative rehearsal. Moreover, extraversion and openness were proportional to elaborative processing. An elaborative style yields more detailed memories of events. Thus, they concluded that retrieval techniques aid learning more than elaborative studying.

Nelson (1992) describes two different parenting styles&colon; pragmatic and elaborative. Better retention was shown with information that had greater cohesion and more elaborative elements. Another method of elaborative encoding is sometimes referred to as the link system. The criterion is whether the objects in question look simple or are elaborative. A list of highly related stimulus words would be better encoded using the elaborative method. Elaborative encoding is a beneficial tool to save and recall information. Instead, the other information gained through elaborative processing would be more beneficial. The courting repertoire of the male is very complex and elaborative.
