While assisting other individuals in a class, adult high ability learners improve:

The correct choice indicates that when adult high ability learners assist others in a class, they significantly enhance their own retention of the material. This phenomenon occurs due to several cognitive and psychological factors. When an individual teaches or assists others, they actively engage with the content at a deeper level, which requires them to consolidate their knowledge and relate concepts in ways that make sense to others.

As they explain ideas or demonstrate skills, high ability learners process the information differently, reinforcing their understanding and helping to encode the material into their long-term memory. This active involvement not only aids their comprehension but also encourages critical thinking, as they must anticipate questions, clarify doubts, and adapt their explanations to the needs of their peers.

This outcome is particularly beneficial in a learning environment where collaboration is valued, as it cultivates a community of learners where knowledge is shared and deepened collectively.
