What This Study Is About
This study explores how common aphantasia (the inability to visualize) and hyperphantasia (having extremely vivid mental images) are among elementary school children. Researchers also wanted to see if a simple, one-question test could accurately identify these conditions in children compared to longer, traditional surveys.
How They Studied It
The researchers worked with 94 fourth-grade students (ages 9 to 10) at a school in the western United States. The children completed two different assessments:
- A single-question test: Students were asked if they could see an actual image in their mind when told to picture a tree, answering with a simple "yes" or "no."
- The VVIQ (Vividness of Visual Imagery Questionnaire): A standard 16-item survey where people rate the clarity of their mental images on a scale from 1 ("no image at all") to 5 ("perfectly clear"). The researchers simplified the wording to make it easier for children to understand.
What They Found
The study found that aphantasia and hyperphantasia might be more common in children than previously thought. About 13.8% of the students scored in the aphantasia range, and 27.7% scored in the hyperphantasia range—both higher percentages than typically seen in studies of adults. Importantly, the one-question test was very accurate: every student who said "no" to seeing a tree also had a low score on the longer survey, and every student with the highest imagery scores answered "yes."
What This Might Mean
These findings suggest that the ability to create mental images is already well-established by age nine. It also suggests that a single, clear question might be a reliable way for teachers to quickly identify students who cannot visualize. This is important because many classroom activities ask children to "picture the story," which may be frustrating or impossible for a child with aphantasia. However, because this study only looked at one group of students in one school, more research is needed to see if these high percentages are the same for children everywhere.
One Interesting Detail
While 13.8% of students were classified as having aphantasia based on the full survey, only 6.5% reported a "total" absence of imagery (scoring the lowest possible 16 points), showing that there is a wide spectrum of how clearly children see things in their mind's eye.
