It can be fun to hold a conversation with a young child. One second you're talking about breakfast cereals and the next you're talking about a cartoon.

An inability to reconcile inferences with another person's perspective is what seems like a limited vocabulary.

The two critical cognitive skills that make it impossible for kids around five years old or younger to read between the lines of a simple conversation are being discovered by researchers.

According to University of Cambridge linguist Elspeth Wilson, when children fail to get what adults mean, that may not just be because they don't understand the words.

The context of a conversation can be too complicated for children to understand.

A variety of skills that allow us to see the world through someone else's eyes is what we take for granted.

Ask the question, "What are you eating?". The questioner can assume that the person isn't eating bananas, toast, and a muffin. Even if not stated it is implied.

The skill of ad hoc implicature allows us to share information without the need for context. There is a lot of psychology in this basic unit of communication.

The person answering the question needs to be aware of the amount of relevant information they are giving. The spoken and missing details are equally important.

Interpersonal communication is underpinned by pragmatic language skills. It's hard to see how much detail is provided in a given context because of the condition.

It is assumed that both individuals can see what the other has experienced. A bowl of cereals on the table is not a list of items in the fridge.

These two skills are easy to integrate as adults. Is it possible that the dual components of inquiry emerge in tandem or are they only to be woven together in time?

Children can develop pragmatic communication strategies of providing relevant information while they are still limited to an egocentric view of their world. They don't need to take into account another's perspective to give a response.

There is a theory of mind where the tiny human tries to read into the wording of your request even if they don't understand it.

Researchers gathered 33 children aged five and six and used a puppet to talk to them.

The child was told to pick cards based on what they saw. The card was clear to both the puppet and the child in some instances. There was a card that the puppet could see that was relevant to the child.

The puppet can see two cards, one with bananas and an apple, the other with apples and oranges, and ask for the card with bananas on it. In addition to the two cards seen by the puppet, there is also a card with bananas.

Four children understood that the puppet was talking about a card with bananas and apples. Only nine people failed to understand that the puppet was implying a card to them.

Most children aren't effectively integrating the different skills together into ad hoc implicature according to the results.

Some of the tests conducted by the researchers with older children show that pragmatic and epistemic reasoning can be practiced on their own. Children can combine them into a single act.

This is an important hurdle for children just starting out in school. Not all new students can reconcile the right response from their perspective with a relevant response from someone else.

It's a good thing you know what the cartoon is about.

The research was published in language learning and development.
