Your Brain Treats Images Like Reality

Mental Imagery and Emotion: A Special Relationship?

Emily A. Holmes and Andrew Mathews. Emotion. American Psychological Association. 2005.

This paper was published ten years before aphantasia had a name. Holmes and Mathews were the first to prove with hard data what therapists had assumed for decades, that imagining something and thinking about it verbally are not the same thing emotionally. If you want to understand why a person with aphantasia responds differently to fear, to music, to therapy, to scary stories, this is where the explanation starts.

The Question

It has long been assumed that mental imagery has a special and powerful relationship with emotion. But very little research had actually put that assumption to a direct test. These researchers wanted to know whether imagining an unpleasant event produces more anxiety than simply thinking about the same event using words. The hypothesis was that imagery would win. But did it?

The Discovery

Participants were randomly assigned to either imagine frightening scenarios as they heard them or to process the same scenarios by focusing on their verbal meaning. Both groups heard identical content. The imagery group showed a significant increase in anxiety by the end. The verbal group showed only a weak trend with no significant change. The effect was specific to unpleasant content. Benign imagery did not produce the same anxiety spike. The researchers also found that after the imagery training, participants rated new ambiguous scenarios as more emotionally threatening overall, suggesting that imagery does not just produce anxiety in the moment but shifts how the whole emotional system interprets incoming information.

The Insight

When you imagine something, your brain does not treat it as hypothetical. It treats it as something closer to real, and your emotional system responds accordingly. Verbal thought about the same content does not produce the same effect. The format of the thought, not just the content, shapes the emotional outcome.

If you remember one thing

How a thought is packaged matters as much as what the thought contains. An image creates a different emotional reality than a sentence about the same thing.

The Connection

The No Picture Needed paper makes the case that students with aphantasia process the world through a system that runs on facts and language rather than images. This study helps explain why that difference has real emotional consequences. Talk therapy, visualization exercises, and coping strategies built around imagining a peaceful place all rely on the very pathway that works differently in aphantasic individuals. Knowing that imagery is the active ingredient in many emotional interventions points directly at why those tools may need to be adapted.

For the teacher: Most engaging strategies assume that imagining something makes it feel more real and more motivating. This research shows that is literally true for most students. It also means that for students with aphantasia, those same strategies produce nothing, not because the student is disengaged but because the emotional ignition switch those strategies rely on works differently.

For the parent: When you tell your kid to imagine how proud they will feel when they finish, or how fun the trip will be, you are trying to generate an emotional preview. This research shows that preview only works if imagery is available. For a kid with aphantasia, you are not being ignored. You are speaking a language that does not produce the feeling you are trying to create.

For the therapist: This paper is the foundation for understanding why visualization-based interventions, safe place imagery, imaginal exposure, future self exercises, may not land the same way with aphantasic clients. It is not resistance. It is not avoidance. The mechanism those tools depend on simply operates differently. Knowing that changes where you start and what you try instead.
