How five-year-olds learn to fear snakes - and how easily that fear can be interrupted

Snakes trigger anxiety in roughly 54% of people, and surveys suggest the average American holds a negative attitude toward them. Drivers have been documented swerving to hit snakes on roads. At least 450 of the more than 4,000 known snake species face elevated extinction risk, and public support for their conservation remains weak - a pattern that researchers at Oregon State University and the University of Regina trace, in part, to what happens in the first five years of life.

A study published in Anthrozoös used more than 100 kindergarten-age children to investigate how early attitudes toward snakes form and whether they can be redirected. The findings point to language as a key mechanism - and to early childhood as an unusually responsive window for intervention.

How the study worked

Lead researcher Denee Buchko of the University of Regina and co-author Jeff Loucks, a professor of teaching at OSU's College of Liberal Arts, designed a three-part experiment. Children were assessed using an induction task - a standard technique for measuring how similar kids believe an animal to be to humans, to other non-human animals, and to non-living objects. The results were compared across conditions that varied what children had been exposed to before the task.

In the first condition, parents looked through a picture book about snakes with their child. A researcher also read the child a storybook about a snake's daily life. That storybook existed in two versions: one that referred to the snake with object-like language ("it" pronouns, no references to feelings or inner states) and one that used personifying language ("she" pronouns, references to the snake's thoughts and feelings).

Children who were read the objectifying version - along with any children whose parents used negative language during the picture-book session - showed a tendency to categorize snakes as unlike other animals. The personifying language had the opposite effect, pushing children to treat snakes as more similar to other creatures.

A baseline that surprised the researchers

Something unexpected emerged when Loucks and Buchko ran a simpler condition: they removed the picture book and storybook entirely and gave children only the induction task, with no prior snake exposure.

"Something unexpected was that kids generally thought that snakes were similar to other non-human animals," Loucks said. But when the picture book and positive storybook were removed, children no longer categorized snakes similarly to other animals. The implication is that without any specific snake content, the default five-year-old categorization places snakes outside the typical animal category.

A third condition replicated the first - picture book, storybook, both versions - and confirmed the initial findings. The pattern was consistent: positive framing or basic educational content about snakes was enough to shift how children classified them; objectifying or negative language moved classification in the other direction.

Why snake attitudes matter for conservation

"Childhood is a critical time for shaping someone's attitudes and behaviors toward animals," Loucks said. "Snakes have a very negative reputation in Western societies and are commonly misunderstood."

The conservation stakes are real. Snakes are predators that regulate rodent and insect populations, and their loss from ecosystems disrupts food webs. Cultural hatred of snakes - reflected in everything from casual road killings to opposition to habitat protection - limits the social and political support needed for conservation programs.

"Some exposure to snakes and learning about their biological needs can act as an inoculation against negative attitudes toward snakes, which can help to engender care and respect for these animals," Loucks said.

The study's sample was drawn from Western, primarily North American cultural contexts, which limits how broadly the findings can be generalized. Attitudes toward snakes vary across cultures - some traditions treat snakes positively or reverently - and the mechanisms shaping childhood attitudes may differ in those settings. The sample size, while sufficient for the study design, is also modest, and effects detected in it warrant replication in larger and more diverse groups.

What the study demonstrates is that snake antipathy is not simply innate. It is built - through parental language, through the books children encounter, through the framing of animals as things rather than beings. And it can be rebuilt in the opposite direction with modest educational intervention, provided that intervention happens early enough.
