Chunking in seven-month-old infants
Previous research shows that the mechanism of chunking is available in seven-month-old infants. This means that chunking can occur even before the working memory capacity has completely developed. Knowing that the working memory has a very limited capacity, it can be beneficial to utilize chunking. In infants, whose working memory capacity is not completely developed, it can be even more helpful to chunk memories. These studies were done using the violation-of-expectation method and recording the amount of time the infants watched the objects in front of them. Although the experiment showed that infants can use chunking, researchers also concluded that an infant's ability to chunk memories will continue to develop over the next year of their lives.

Working memory appears to store no more than three objects at a time in newborns and early toddlers. However, In research has shown that 14-month-old infants, like adults, can chunk using their knowledge of object categories: they remembered four total objects when an array contained two tokens of two different types (e.g., two cats and two cars), but not when the array contained four tokens of the same type (e.g., four different cats). It demonstrates that newborns may employ spatial closeness to tie representations of particular items into chunks, benefiting memory performance as a result. Despite the fact that newborns' working memory capacity is restricted, they may employ numerous forms of information to tie representations of individual things into chunks, enhancing memory efficiency.
