Final answer:
Interleaved practice is a study technique that involves mixing up different types of study content to improve memory retention and make learning more effective.
Step-by-step explanation:
The study technique that involves mixing up different types of study content is known as interleaved practice. This technique has been shown to improve memory retention and learning efficiency. By varying the type of material studied, the brain is encouraged to make more connections and to remember information more effectively, as opposed to focusing on a single topic for an extended period, commonly referred to as blocked practice. Interleaved practice aligns with several key memory consolidation strategies, such as distributed practice and elaborative rehearsal, which involve spreading out study sessions over time and linking new information to existing knowledge respectively. Additionally, this approach can help to build a network of retrieval cues for more easily recalling the information later on.
