Infant cognition is a fascinating field that explores how babies understand the world long before they can talk. While infants don’t use words, research reveals that they think in ways we’re only beginning to understand. These insights can be helpful for parents wanting to connect with their babies and for scientists studying human thought and development.
Can Babies Really Think Without Words?
It’s natural to think that language and thought go hand-in-hand. After all, adults often rely on words to explain things. However, babies show signs of infant cognition long before they say their first word. For example, studies reveal that babies can recognise shapes, sounds, and even simple human actions. Without needing words, infants make associations that seem almost intuitive, suggesting that they possess an early form of understanding.

Research shows that infants connect sounds with shapes even before they know words like “round” or “sharp.” For instance, babies tend to link round shapes with softer sounds, a natural association that may be built into our biology. This discovery hints that babies might have some understanding of the world that isn’t based on language.
Understanding Actions: Babies and Social Cues
Infant cognition goes beyond recognising shapes and sounds. Babies also seem to pick up on simple social cues and actions. A recent study found that infants can distinguish between people helping or harming each other. In these experiments, babies responded differently when a person helped another versus when someone appeared to harm them. This response suggests that babies can assign simple roles to people, like “helper” and “harmful person.”
Interestingly, babies also react when these roles are reversed in a scenario, almost as if they can tell that something isn’t right. For instance, they may look longer or show signs of confusion. This indicates that infants understand simple actions and relationships even without words, which can help parents better engage with their little ones.
What the A-Not-B Task Tells Us About Infant Cognition
One way researchers test infant cognition is through the “A-not-B” task. In this task, a toy is repeatedly hidden in the same place, called location A, and the baby finds it each time. Then, the researcher moves the toy to location B while the baby is watching. Despite seeing this, most babies under a year old still look for the toy in location A.
This behaviour, known as “perseveration,” shows that babies are still learning about object permanence, or the idea that objects exist even when unseen. This simple but fascinating task shows that babies are processing the world around them, even if their understanding is still developing.
Sound and Shape Connections: A Glimpse into the Infant Mind
One of the more surprising findings in infant cognition is that babies naturally associate certain sounds with specific shapes. For instance, babies seem to link round shapes with “soft” sounds, like “bouba,” and jagged shapes with “sharp” sounds, like “kiki.” What’s remarkable is that this association appears before any language learning, suggesting it may be a natural part of human understanding.
This innate connection between sounds and shapes reveals that babies start forming mental connections early on. Parents might notice how babies respond differently to certain sounds or shapes, indicating a deeper cognitive process at play.
Why Does Infant Cognition Matter?
Studying infant cognition is about more than understanding babies; it’s about exploring the origins of human thought. For parents, understanding these early cognitive skills can help in connecting with their babies through nonverbal cues, gestures, and sounds. For scientists, it raises exciting questions about the nature of thought and language. If babies can think without words, it may challenge ideas about how human understanding develops and could even impact our understanding of artificial intelligence.
Final Thoughts: Babies Think More Than We Realise
The mind of an infant is more active than most people realise. Babies are busy making sense of the world around them, from recognising social cues to connecting shapes and sounds. While they may not speak, they’re still learning, thinking, and exploring their surroundings in remarkable ways. The study of infant cognition not only changes how we see our youngest family members but also sheds light on how human intelligence begins.
