Visual Imagery and Improv: memory, recall, and the phantasia spectrum

Most improvisers use visual imagination in some way without thinking much about it. You picture the space you’re in. You see your character. You look at something your scene partner has described and you see it too. What varies between people is how vivid that experience is, how automatically it happens, and what it does when it kicks in.

This episode series is about that variation and what it means for your practice.

This page covers episodes 10 and 14 of the Your Improv Brain podcast. Episode 10 covers what hyperphantasia and aphantasia are and how visual processing shows up in improv. Episode 14 focuses on how to use visual imagery specifically for memory and recall in scenes and sets. You can find both of these embedded below.

The spectrum: hyperphantasia to aphantasia

Visual imagination exists on a spectrum. At the vivid end is hyperphantasia: photorealistic mental imagery, connected to other sensory details like sound, emotion, humidity, and light. At the other end is aphantasia, where the mind doesn’t form visual representations at all.

About 2 to 3 percent of people are at each extreme. Everyone else is somewhere in the middle.

Hyperphantasia is not the same as photographic memory. Photographic memory is short-term and highly precise recall of something recently seen. Hyperphantasia is more about constructing and reconstructing environments with vivid detail, including completely fictional ones. Someone with hyperphantasia can put themselves in a location they’ve never been to, look around, and describe what they see.

Someone with aphantasia doesn’t form a visual picture. That doesn’t mean memory is weaker or that improv is harder. Other forms of memory and recall are doing the same work. It’s basically having different tools, not fewer or broken tools.

Both hyperphantasia and aphantasia have been described as forms of neurodivergence, or neurocognitive variation. Neither is considered a disorder. Like a lot of things in the neurodivergent space, there’s overlap with other conditions, and the experience varies significantly between individuals.

What hyperphantasia actually feels like in improv

For a long time it seemed normal to assume everyone experienced visual imagination the same way. This is a fairly common neurodivergent experience: discovering that something you just assumed was universal is actually quite specific to how your brain works.

In a scene, hyperphantasia means stepping into an environment mentally before describing it. You put yourself there first, look around, and then describe what you see rather than inventing details as you talk. The environment updates in real time as scene partners add to it. If someone says there’s a rug in the center of the room and you had a table there, the table just disappears. The space adjusts itself.

Scenes with strong visual environments tend to stick in memory for a long time afterward. Specific moments from scenes done years ago can still be recalled in detail, including what the character looked like, where the light was, what the space felt like. This is the same memory mechanism being used, just applied to imagined spaces.

One aspect of this worth noting: remembered scenes often appear from a third-person perspective, more like watching a film than replaying a first-person experience. That camera angle view also shows up when seeing your own character, which turns out to be one of the more useful applications of hyperphantasia in improv.

Character creation

Visualizing your character at the top of a scene, before you’ve said a word, before you’ve even started, can set up physicality, voice, posture, and point of view almost automatically. Seeing what the character looks like, treating it like a costume you’re putting on, lets a lot of character work happen at a level you don’t have to consciously manage during the scene.

Even if you’re playing someone close to yourself, you can still look at what that version of you looks like right now. Are you tired? Shoulders back? Hunched? All of those things are already giving you something to work from. This is one of the techniques that was in use from the very earliest scenes, before there was any improv training to back it up, because it’s just wired in.

Emotions and alexithymia

One area where visual processing connects to something that doesn’t often come up in improv training is the use of flash memory to access emotions.

When asked to perform an emotion, or given an emotion word to work with, the approach that works is to find a memory where something close to that feeling was present. Using hyperphantasia, you can return to that moment, see it, feel what was there, and then bring that into the scene. The label becomes almost irrelevant. You’re not trying to perform “anxious.” You’re returning to a specific afternoon and using whatever was actually there.

This came out in a class moment worth describing. A teacher asked what emotion a scene had been playing. The answer that came out was a paragraph describing a physical experience, not a word. The teacher’s response was: if that’s how you access an emotion, just keep doing that. Both routes are valid.

This connection between visual imagination and emotion access is part of why hyperphantasia and alexithymia ended up being discussed in the same breath. They interact. If you have difficulty attaching words to feelings, visual memory can be one of the ways around that. The episodes on alexithymia (episodes 18 and 19) go into this in much more depth. You can find those episodes and an article here.

Using visual memory for recall in scenes

The more detailed the visual environment you build at the top of a scene, the easier it is to retrieve things from it later.

This works the same way as a memory technique used outside of improv for years: to remember choreography mid-class, you’d mentally return to the room where it was practiced, see the paper, and use that visual return trip to retrieve the information. Not reading anything, just going back to the experience of being there. The same mechanism works in scenes.

If you need to call back to something specific from earlier in a set, you can rewind mentally to that moment, see what was established, and pull the detail you need. It takes a fraction of a second. And the stronger the visual you built at the time, the more reliably you can return to it.

This is also why it helps to keep checking back in on your visual environment throughout a scene rather than dropping it once the scene gets going. You establish the space at the top and then forget about it. Periodic check-ins keep the space alive and accessible.

Forms that work well for this

Some improv forms are naturally more visual than others. Monoscenes, macroscenes, and the close quarters form all involve staying in one environment for an extended period. That consistency makes it much easier to build and hold a strong visual, because you aren’t constantly resetting to new spaces.

For second beats and analogous scenes, this becomes particularly useful. If you build the first beat with a strong visual progression throughout, with specific objects and details accumulating as the scene moves, those become the anchors for the second beat. You see the first beat, find the equivalent element, and carry it across. The mapping is fast because you’re working from what you can see rather than what you can remember verbally.

On forcing it

Visual imagination is wired in. You can’t train your way to more of it than you have. What changes with experience is the improv skill around it: listening better, relaxing more in scenes, building stronger base realities. When those things improve, the visual processing you already have gets easier to access because you aren’t splitting attention across so many other demands at once.

Trying to force visual elements into scenes, spraying details into your mind’s eye, willing information to appear, tends not to work well and takes the enjoyment out of it. The more useful approach is to set yourself up and let it do what it does. Pause at the top of a scene. Take a beat. Put yourself somewhere visually before you start talking. Then let the scene move.

The downsides

Strong visual imagination is a tool, and like most tools it has a less useful side. Photorealistic recall applies to negative memories as well as positive ones. PTSD and similar conditions interact with hyperphantasia in real ways. Certain kinds of content in films and shows can be hard to watch for this reason. Distraction, over-analysis, getting too deep into a constructed scenario when you’re supposed to be doing something else, these are all real costs that come alongside the benefits.

It’s worth knowing that about yourself if it applies to you.

Listen to both episodes

Episode 10 covers what hyperphantasia and aphantasia are, how visual processing shows up across different areas of improv, and what the experience is like from the inside.

Episode 14 picks up from there with a specific focus on memory and recall: flash memory, setting up scenes for recall, second beats, and forms that reward strong visual environments.
