Abstract

The ability to remember past experiences and imagine future scenarios is thought to be closely tied to visual imagery. People can differ greatly in their ability to form mental images, with some having difficulty doing so altogether (aphantasia). This study aimed to explore the impact of aphantasia on memory recall and future thinking. Participants with aphantasia and a control group were evaluated on a form of the Autobiographical Interview, which measures the specific and rich details of episodic memories. The results showed that individuals with aphantasia produced fewer details for both past and future events compared to the control group, particularly for novel future events. This effect was mainly due to reduced visual detail retrieval, lower richness of simulated events, and reduced language use in aphantasia participants. This study provides evidence that visual imagery plays a crucial role in memory recall and future thinking.

What This Study Is About

This study explores how the absence of a "mind's eye" affects the way people remember their past and imagine their future. Researchers wanted to know if people with aphantasia—who cannot voluntarily create mental images—experience memories and future scenarios with less detail or a different emotional quality than those with typical imagery.

How They Studied It

The researchers compared 30 people with aphantasia to 30 people with typical visual imagery. Participants completed the Autobiographical Interview, a task where they described personal memories from different life stages (childhood, early adulthood, and the recent past) and imagined possible future events. Researchers then analyzed these stories, counting "internal" details (specific happenings, time, and place) and "external" details (general facts or unrelated information).

What They Found

People with aphantasia reported significantly fewer sensory details in both their past memories and their imagined future scenarios. While they were just as good at describing the "who, what, and where" of an event, they struggled to describe the visual or "episodic" specifics that make a memory feel like re-living a moment. Interestingly, while their memories were less vivid, people with aphantasia did not show significant differences in their spatial memory—the ability to understand where objects are located in a layout.

What This Might Mean

The findings suggest that mental imagery—the ability to picture things in your mind—acts as a "scaffold" for episodic memory. Without this visual tool, memories may feel more like a list of facts rather than a mental movie. However, the study also shows that the brain has different ways of storing information; aphantasic individuals likely rely more on factual (semantic) and spatial systems to navigate their personal histories.

One Interesting Detail

When describing their memories, people with aphantasia used significantly fewer words related to emotion. This suggests that being able to "see" a past event in the mind's eye may be closely linked to how strongly we feel the emotions associated with that memory.
