Answer:
- Symbolic function; language
Step-by-step explanation:
Piaget states that 'symbolic function' lies at the center of 'language.' Symbolic function is characterized as the ability that allows the children to use symbols to signify objects or events. In the age of 2-4(preschool kids), the children develop this ability and they are able to develop mental images representing distinct objects. This is the beginning of the use of language as they learn to use words to represent ideas or objects that are a major advancement for the preschool children and takes them towards the Intuitive thought substage.
