Which technique is helpful in improving memory retention during training?

Chunking information is a highly effective technique for improving memory retention during training because it organizes information into manageable units, making it easier for the brain to process and recall. When learners encounter a large volume of information, it can be overwhelming, which may hinder retention. By breaking down complex information into smaller, more digestible chunks, learners can create associations and patterns in their minds, facilitating better understanding and recall.

For example, instead of trying to memorize a long string of unrelated numbers, learners can group them into sets (like phone numbers) which helps in improving cognitive processing and memory retention. This technique leverages the brain's natural ability to remember grouped information more efficiently than isolated facts.

While repetition of facts and immediate testing after instruction can also promote retention, chunking provides a foundational strategy that enhances comprehension before these other techniques are applied. Long lectures may lead to disengagement and decreased retention, as they can overwhelm learners without facilitating active processing of the information.
