• Encoding is the process of converting information into a memory format, not specifically for boosting short-term memory retention.
• A schema is a mental framework for organizing knowledge, unrelated to enhancing short-term memory capacity/retention.
• Free recall is a memory retrieval method, not a tool to increase short-term memory.
