Encoding memories: mnemonics, chunking, spacing and serial position

What the exam asks

• Concept application (MCQ): Identifying which encoding strategy (such as the method of loci, chunking, or distributed practice) a person is using in a scenario.
• Data interpretation (MCQ & AAQ): Reading line graphs or tables of word-recall experiments to identify the serial position effect, primacy effect, or recency effect, and explaining what happens when a delay or distractor task is added.
• Argumentation (EBQ): Using encoding principles (like the spacing effect or hierarchies) as your outside psychological concept in Part B(ii) or C(ii) to explain why a specific study intervention improved test scores.

Core ideas

How encoding shapes storage and retrieval

Encoding is the process of getting information into the memory system. How deeply and systematically you encode material determines how durably it is stored in long-term memory (LTM) and how easily you can retrieve it later. Effortful encoding strategies build rich retrieval cues and connect new items to existing knowledge.

Mnemonic devices and the method of loci

Mnemonic devices are memory aids, especially techniques that use vivid imagery and organizational frameworks to help encode information into working and long-term memory.

• Method of loci (memory palace): A spatial mnemonic in which you mentally walk through a familiar route or building (such as rooms in your home) and visually associate each item you need to remember with a specific location along the path. When retrieving the list, you mentally re-walk the route.
• Other mnemonics include acronyms, acrostics, and peg-word systems, which pair concrete mental images with abstract words.

Grouping information: chunking, categories, and hierarchies

Working memory has a limited capacity, so organizing individual bits of information into larger, meaningful units makes encoding far more efficient:
