Final answer:
Redundancy in learning increases memory retention and establishes stronger connections with existing knowledge through techniques such as elaborative rehearsal, distributed practice and the self-reference effect.
Step-by-step explanation:
Redundancy increases learning by enhancing memory retention and making connections between new information and what is already known. Utilizing techniques like elaborative rehearsal encourages engagement with the material by thinking about its meaning and relating it to previous knowledge. Practicing distributed practice rather than cramming allows more efficient memory consolidation over time. The self-reference effect makes learning personal and thus more memorable by relating the material to one's own experience and integrating it with existing knowledge webs. Furthermore, repeated exposure and rehearsal of material can lead to a deeper understanding, greater recall, and more persistent memory over time.
