Understanding the Core Concept of Accommodation
Accommodation is the cognitive process of altering one's existing ideas or schemas to include new information that conflicts with what was previously known. This is different from assimilation, where new information is incorporated into existing schemas without altering them. Accommodation forces a fundamental change in how we understand the world. This principle was first described by Swiss psychologist Jean Piaget and is a cornerstone of his theory of cognitive development.
The Classic Piagetian Example: Dogs and Cats
A child has an existing schema that all four-legged, furry animals are "dogs." This is a simple, broad category. The child sees a new four-legged, furry animal—a cat—and initially calls it a "dog." When corrected by a parent, who explains that this animal is a "cat," the child must accommodate this new information.
- Original Schema: Furry, four-legged creature = Dog.
- New Information: A cat is also a four-legged, furry creature, but it's different from a dog.
- Accommodation: The child modifies their schema. Instead of all four-legged, furry animals being dogs, the child now has a more complex understanding. They might create a separate schema for "cats," or create a broader schema for "pets" that includes different animals with their own distinct characteristics. The child's mental model of the world has been permanently altered to fit this new experience.
Accommodation Beyond Psychology: Eye Focus and Visual Health
In the realm of general health, one of the most direct and biological examples of accommodation is how the eye functions. Ocular accommodation is the eye's ability to adjust its focus for objects at varying distances, ensuring a clear image is formed on the retina.
- Looking at a Distant Object: The ciliary muscles relax, and the suspensory ligaments pull, causing the lens of the eye to flatten. This decreases the lens's refractive power, allowing it to focus on far-away objects.
- Looking at a Nearby Object: The ciliary muscles contract, and the suspensory ligaments slacken. This causes the lens to become thicker and more curved. The increased curvature gives the lens more refractive power, allowing it to focus on close-up objects. This is why reading a book requires a different physical adjustment than looking at a billboard across the street.
Cognitive Accommodation in Adults: A Mental Health Perspective
Accommodation isn't just for children. Adults also constantly adjust their mental schemas, particularly in areas related to mental health, stereotypes, and personal growth.
A Person Adjusts Their Prejudice
Someone raised with a prejudiced schema about a particular social or cultural group might enter college and, through direct interaction and new experiences, realize their existing beliefs are fundamentally wrong. The individual must then accommodate this new, conflicting information, leading to a profound change in their understanding of the world and the people in it. This requires more than just adding a new fact; it demands a restructuring of deeply held beliefs.
A Patient Changes Their Health Habits
A person has a lifelong schema that they are generally healthy and their habits have no major consequences. They are diagnosed with a chronic illness, such as diabetes. To manage their health, they must accommodate this new reality, which involves changing their framework of how they view food, exercise, and lifestyle choices. This isn't a small adjustment but a significant re-shaping of their entire health-related schema.
Accommodation vs. Assimilation: A Comparative Analysis
To fully grasp the power of accommodation, it's helpful to compare it directly with assimilation.
| Feature | Accommodation | Assimilation |
|---|---|---|
| Mechanism | Modifies or creates a new schema. | Incorporates new information into existing schema. |
| Effect | Causes a fundamental change in understanding. | Reinforces or expands existing knowledge. |
| Example (Piaget) | A child learns a cat is not a dog and creates a new "cat" schema. | A child sees a new breed of dog and calls it a "dog". |
| Analogy | Buying a new, larger bookshelf because your new book doesn't fit on the old one. | Finding an empty spot on your existing bookshelf for a new book. |
| Outcome | Leads to a more complex and nuanced understanding. | Maintains a state of cognitive equilibrium. |
How Accommodation Fuels Learning and Personal Growth
Accommodation is not just a passive process; it's a driving force for growth. When we encounter information that doesn't fit our existing worldview, it creates cognitive disequilibrium. This mental discomfort motivates us to resolve the conflict by adjusting our understanding. This constant push-and-pull between assimilation and accommodation is how we progress from simple, broad schemas to complex, detailed ones. Whether it's a child learning about different animals, an adult overcoming prejudice, or our eyes adapting to shifting visual demands, accommodation is an essential mechanism for adapting and thriving in a complex world.

Conclusion: Accommodation is an Action of Change
The definitive answer to "Which example shows accommodation?" is any instance where an individual fundamentally alters an existing mental framework to incorporate new, conflicting information. From a toddler creating a new category for a cat to an adult revising a prejudice, accommodation is the engine of change and growth. It's a continuous process that allows us to adapt our understanding of the world, making our mental schemas more sophisticated and accurate over time. Understanding this process, both psychologically and physically, is key to comprehending human development and health.
