What this dot point is asking
AQA wants you to explain encoding (how information is stored as acoustic or semantic), describe the reconstructive nature of memory using Bartlett's War of the Ghosts study, and explain how context and cues affect retrieval. This is part of the Memory topic in Paper 1, and Bartlett is a named study you must be able to describe and evaluate.
Encoding: acoustic and semantic
Short-term memory mainly uses acoustic encoding (which is why we tend to confuse similar-sounding items, like the letters B and P, in the short term), while long-term memory mainly uses semantic encoding (which is why we remember the gist of what we read rather than the exact words). Knowing which store uses which form of encoding links this dot point directly to the multi-store model.
The reconstructive nature of memory: Bartlett
Retrieval, cues and context
Retrieval is the process of getting stored information back out of memory, and it depends heavily on cues. A cue is anything associated with the original memory that helps trigger it. Context-dependent retrieval means recall is better when the external environment matches the one at learning (a classic demonstration is divers recalling word lists better in the same environment, land or underwater, where they learned them). Providing the right cue can restore a memory that seemed forgotten, which links to retrieval failure as an explanation of forgetting.
Try this
Q1. Explain the difference between acoustic and semantic encoding. [2 marks]
- Cue. Acoustic encodes by sound (mainly short-term memory); semantic encodes by meaning (mainly long-term memory).
Q2. State what Bartlett's study showed about memory. [2 marks]
- Cue. That memory is reconstructive, rebuilt using schemas, and can be distorted.
Q3. Identify one factor that improves retrieval. [1 mark]
- Cue. Cues (or matching the context at learning).

AQA 20184 marksDescribe Bartlett's War of the Ghosts study and what it showed about memory. (Paper 1, Section B)Show worked answer →
A 4-mark item that rewards the method, the findings and the conclusion.
Bartlett asked British participants to read an unfamiliar Native American folk story (War of the Ghosts) and then to recall it repeatedly over time. He found that recall became shorter and was distorted: participants changed unfamiliar details to fit their own cultural expectations (for example, changing "canoes" to "boats" and dropping references to ghosts that made little sense to them). This showed that memory is reconstructive: we do not store an exact copy but rebuild memories using our existing schemas, which can distort them.
Markers reward the method (reading and repeatedly recalling an unfamiliar story), the finding (recall shortened and altered to fit expectations), and the conclusion (memory is reconstructive and shaped by schemas).
AQA 20223 marksExplain the difference between acoustic and semantic encoding. (Paper 1, Section B)Show worked answer →
A 3-mark Explain item rewards a definition of each plus where each is mainly used.
Acoustic encoding is storing information by its sound (how it sounds when spoken or heard); it is the main way short-term memory encodes information. Semantic encoding is storing information by its meaning; it is the main way long-term memory encodes information. The contrast is sound versus meaning, and the link to the multi-store model (short-term acoustic, long-term semantic) shows understanding.
Markers reward both definitions and ideally the link to which store mainly uses each. Saying both are "just remembering" without the sound-versus-meaning contrast caps the marks.
