Images aren’t just worth a thousand words, they shape what we believe. In our increasingly visual world, the images we see aren’t just decoration, they’re powerful engines of perception. Studies across disciplines reveal that visuals don’t simply illustrate reality, they interpret it.
Research in pictorial perception has shown that purely visual cues embedded in pictures can alter how we interpret size and depth. For example, one study found that adding pictorial depth cues (such as linear perspective or texture gradients) affected people’s size judgments in images (Farran, Whitaker, & Patel, 2009). Meanwhile, contextual imagery in newsfeeds or media can shift perceptions of bias and credibility simply by the types of visuals used.
Consider: one study found that when a photograph includes a smaller image of a person within the image, viewers tend to see that depicted person as less “real” or less capable of feelings or agency compared to someone pictured directly.
When a Picture Becomes a Teacher
Visuals have long been known to boost understanding and recall, a phenomenon sometimes called the “picture superiority effect.” But as Kennedy et al. (2011) observed in adolescent health education, thetypeof imagery matters. Pictorial materials used in reproductive health campaigns influenced how young people perceived their own agency and risks. Clear, respectful visuals helped adolescents relate information to their lives while overly clinical or fear-based imagery often alienated them. The study shows that pictures can empower, but only when designed with empathy and context.
Enochsson et al. (2024) explored the use of digital visuals in preschool science learning. Teachers who integrated videos, diagrams, and photographs found that children engaged more deeply with abstract scientific concepts like movement or growth, when supported by images. However, the study warned that without guidance, visuals could mislead. Meaning children might interpret animations as literal reality rather than symbolic representations. Here again, perception is powerful but it needs thoughtful scaffolding.
Playing It Smart: Tips for Navigating Pictorial Influence
1. Pause and question: When you see a photo accompanying a claim or headline, ask: What is the picture doing? Is it simply illustrating, or is it framing the message?
2. Notice visual cues: Depth, size, proximity, cropping, all of these influence your perception.
3. Check for consistency: If the image suggests something emotionally strong (shock, outrage, awe) ask whether the text supports that tone or whether the picture is doing extra heavy lifting.
Ultimately, images do far more than capture moments, they construct meaning. Every photograph, film frame, and digital graphic subtly influences how we understand people, events, and ideas. As consumers of a constant visual stream, we must recognize that images are not neutral reflections but active participants in shaping truth and belief. To see critically, then, is to question not only what an image shows but what it wants us to see.
