In 1975, Michael Halliday identified that childrens langauge in their early years has 7 key functions. He believed that children are motivated to learn language as they believe it enables them to serve certain functions for them, such as to express their needs. This is ultimately named 'learning how to mean'.
4 of the 7 functions are labelled as helping the child satisfy physical, social and emotional needs.
Instrumental: When the child uses language to express their needs - Example - " I Want milk"
Regulatory: Where language is used to tell others what to do - Example - "Come here"
Interactional: Where language is used to form a relationship/ socially interact with others - Example "Love you mum"
Personal: Use of language to express the speaker's identity or/and feelings - Example - "I've been good today"
The other 3 functions are heuristic, imaginative, and representational. These help learning children understand the environment they are in.
Heuristic: When language is used to gain knowledge about the environment - Example - a running commentary of a child's activities "look at the fox"
Imaginative: Language is used to create expand the child's imagination, usually by telling stories
Representational: Using language to convey facts and information - Example "I have long hair".

John Dore's infant language functions
These are much more simple and basic to understand compared to Halliday's slightly more in-depth theory. Still similar to Halliday in the fact that children still learn language to develop necessary functions, they are just a lot more basic.
Labelling - Naming or identifying a person, object or experienceRepeating - echoing language spoken by a more accomplished speaker
Answering - Directly responding to an interrogative or declarative (or any utterance) by another speaker
Requesting action - demanding something e.g. food or drink
Calling - shouting/ loudly talking to attract attention
Greeting - simply saying "hi" or "hello"
Protesting - Objecting to a request
Practising - Repeating language that the child speaks when no adults are assisting, trying to independently develop their language.
In the transcript, relating to John Dore's infant language functions, it is actually the accomplished speaker who does the repeating of words or phrases, acting as interrogatives; this may be used to enhance the learning of the young speaker and encourage them to keep talking which will inevitably enhance their language skills and ability.
Furthermore, just 1 of the 4 functions used to satisfy physical, social and emotional needs (Halliday) was used "i got food on the floor". The reason that the other 3 from that category such as instrumental function were not used was because Zach was mainly talking about what he was doing at that moment, not needing to request for things. Because of this, many heuristic and representational functions were used because the interrogatives being asked allowed for a running commentary style conversation to occur, where Zach was detailing what he was doing throughout the conversation, also showing the simple 'labelling' occuring from John Dore's theory, such as "here's the skins".
