How Do Memory Athletes Study Differently? The Science of Memory, Imagination, and Thought

ResearchJuly 14, 2026By MemorySports9 min read

Memory athletes select important information from what they understand, organize it with trained structures, and retrieve it again. Accessible memory then supplies material for review, simulation, and discovering new relationships.

A student once asked a perceptive question: after one or two years of mnemonic training, might a skilled learner take in a book almost immediately and then do the understanding and restructuring inside the mind?

The intuition captures something important. When mnemonic techniques become familiar, it becomes easier to close the book, bring concepts and cues back, compare them, change their relationships, generate examples, and run mental simulations. The change, however, is less a reversal from “understand then store” to “store then understand” than a major improvement in how selected information is organized and retrieved.

The short answer: encoding and retrieval change

Both an untrained reader and a skilled mnemonist pay attention to a text and understand its meaning. A memory athlete's advantage is a set of prepared structures available as information arrives. Those structures help select key ideas and connect them to images, locations, and order, creating a route for later retrieval.

Memory athletes turn digits, cards, and words into familiar images, then connect those images to a well-known place or sequence. Each item is stored together with a route for finding it again.

In a study of world-class memory performers, Maguire and colleagues linked exceptional performance to spatial learning strategies rather than extraordinary general intelligence or photographic memory. Their advantage looked less like a storage device that absorbs everything and more like a trained system of routes for holding and finding information.

What actually changed in studies of memory athletes?

Dresler et al. (2017) compared 23 top-ranked memory athletes with untrained controls and also gave novices six weeks of method-of-loci training. After training, the novices' functional connectivity patterns became more similar to those of the athletes, and those changes were associated with memory gains months later.

In related work, Wagner et al. (2021) recruited 51 male university students and analyzed 50. The loci group completed forty 30-minute sessions across six weeks and improved on word recall and 24-hour word-recall performance. At four months, 45 participants encoded the same word list used at the initial test. The study directly shows continued use of a trained strategy on a word-list task four months later.

A 2025 systematic review and meta-analysis pooling 3,006 adults found a large advantage for immediate serial recall over rehearsal (Ondřej, 2025). However, none of the assessed experiments was rated low risk of bias, 68.24% were rated high risk, and heterogeneity, publication bias, and small-study effects contributed to a GRADE certainty rating of low to very low. The large pooled estimate should therefore be interpreted cautiously and within the narrow task of linking ordered information to a spatial scaffold for immediate recall.

These findings show a stronger ability to encode selected information with a practiced structure and later retrieve it by following that structure. The research tasks focused mainly on word lists and ordered recall.

So how does the real study workflow change?

Synthesizing these findings with retrieval-practice and self-explanation research and training experience, MemorySports proposes the following practical sequence:

First pass — build the map: read quickly to identify the topic, chapter structure, key questions, familiar ideas, and unknown ideas.
Close the source and recall: explain what you just read in your own words and see how much of the large structure remains.
Second pass — select the anchors: choose the concepts and keywords that matter for the exam, project, or understanding.
Stabilize them with mnemonics: connect those selected ideas to images, locations, stories, or a number system.
Retrieve after a delay: recall without the source, then compare with it to repair details and relationships.

A major strength of a skilled mnemonist is keeping useful concepts available after the source is closed and summoning them reliably when needed.

If you are new to spatial encoding, start with how to build a memory palace. For a digit-image system, continue with how to memorize numbers fast.

Why does remembered knowledge expand the range of thought?

Working memory actively handles a small amount at once. Modern work that separates rehearsal and chunking from the underlying central store estimates its capacity in young adults at about 3–5 meaningful items; the exact number depends on the task and on how an item or chunk is defined (Cowan, 2010). Experts work within that capacity by rapidly activating organized knowledge from long-term memory through retrieval cues. Ericsson and Kintsch's long-term working-memory theory is a classic account of this skill.

The mind retrieves a relevant concept, connects it to the current thought, and moves to the next. Accessible memory becomes an internal workspace that can be searched.

Learning research repeatedly confirms the value of retrieving and explaining:

A classroom retrieval-practice meta-analysis covering 222 studies and 48,478 students found that quizzes and recall improved learning.
A meta-analysis of retrieval transfer found that recalled knowledge can carry into new problems and inference.
A self-explanation meta-analysis found stronger learning when students explained causal and conceptual relationships in their own words.

This makes the sequence “retain it → recall it without the source → rearrange it → change the relationships → discover a new structure” a realistic learning process. Memory preserves the materials; retrieval and self-explanation set them in motion.

A change experienced in training: the code editor in the mind

This section is a first-person account from the lead trainer at MemorySports, who has trained and taught mnemonic techniques.

One change I have experienced through training and teaching mnemonics is the ability to continue a detailed mental simulation after the source is closed.

During a period when I was studying programming intensively, I would first look up the concepts and syntax needed for a feature, then resist the urge to type immediately. Instead, I would open a code editor in my mind, place lines of pseudocode, and follow the execution flow. The real code usually behaved as expected. When an error appeared, I could recall earlier code and search for likely points of conflict.

The concepts, syntax, and structure of earlier code remained available enough for me to recombine and run through them mentally. In my experience, when memory held the materials, I could try them in different orders.

A second change I experienced concerned mental imagery itself. As I repeatedly turned what I saw into images and reconstructed those scenes during retrieval, I felt my imagination become richer and my mental images increasingly clear. In my own practice, both encoding and retrieval worked as exercises in actively moving imagination.

What does “memory is imagination” mean scientifically?

Episodic memory reconstructs experience from cues, sensations, places, and semantic knowledge. When imagining the future, the mind draws people, settings, actions, and emotions from past experience and combines them into a new scene.

A neuroimaging meta-analysis by Benoit and Schacter (2015) found that remembering past events and simulating future events recruit a shared core network including the hippocampus. Schacter and Thakral (2024) describe flexible recombination as a process connecting memory, planning, and imagination.

In the language of mnemonics:

In visual or scene-based mnemonics, unfamiliar information is imagined as a scene during encoding.
During retrieval, the scene and its relationships are reconstructed.
During review, the same scene becomes faster and more stable to summon.
During application, elements of the scene are changed or connected to other memories.

“Memory is imagination” is therefore a practical way to say that imagination becomes a central working tool for making, retrieving, and using memory.

Can mnemonics work without a vivid picture in the mind?

Imagination works through several channels: vivid visual scenes, position and direction, language and rhythm, sound, movement, and bodily sensation. The channel that fits you best can become a strong retrieval cue.

Aphantasia research illustrates this range. In a drawing task, participants with aphantasia recalled fewer visual object details but preserved spatial placement as accurately as controls (Bainbridge et al., 2021). Reeder et al. (2024) showed that nonvisual spatial and sensorimotor strategies could support precise visual working-memory performance.

The goal is to find the imaginative channel that works for you. Use scenes when visual imagery comes easily, locations and routes when spatial sense is stronger, or sentences, rhythm, and narrative when language is stronger. A memory palace provides an ordered relational structure for those cues.

Memory and creativity: retrieving materials and rearranging them

A 2026 individual-differences study found that details retrieved from episodic memory and semantic knowledge were both associated with future imagination and divergent thinking, with semantic memory the strongest predictor of divergent thinking (Thakral et al., 2026). When knowledge is rich and accessible, more material is available for comparison and combination.

This individual-differences study shows associations between accessible episodic and semantic material, simulation, and divergent thinking. Evaluating the effect of mnemonic training on general creativity requires a separate intervention study that applies the training directly.

Creativity often looks less like something appearing from an empty space and more like remembered elements entering a new relationship. Placing a concept in a different context, reversing cause and effect, or applying an old code structure to a current problem are all forms of rearrangement.

The role of mnemonics here is to organize material for thought in an accessible form. New relationships emerge as the thinker compares, transforms, and tests that material.

A five-step routine to try today

Read one page or section quickly and choose one central question.
Close the source and recall its structure and keywords in your own words.
Read again to correct missing points and misunderstood relationships.
Connect only the essential concepts to images, locations, stories, or another cue system that fits you.
Recall without the source one day and several days later, then compare at the end.

For concrete timing and recall settings, continue with training short-, medium-, and long-term memory. For the underlying capacity, forgetting, and spacing effects, see how memory is stored and why we forget.

The answer in one sentence

A skilled mnemonist selects important information from an understood structure, builds strong retrieval routes, and keeps using that knowledge after the book is closed—to review, simulate, and create new relationships.

When memory remains available, imagination retains materials. When imagination has materials, thought can keep moving even after the source is out of sight.
