Jean Plagets 2nd theory is Pre- operational between ages 2.7 where children learn proper grammar and syntax True False

False.Jean Piaget's second stage of cognitive development is the Preoperational Stage, but it occurs between the ages of approximately **2 and 7**, not 2.7. While children do develop language skills during this stage, including grammar and syntax, the hallmark of the preoperational stage is the development of **symbolic thought**, which allows children to represent objects and events mentally. This is evident in their increasing use of language, make-believe play, and drawing. However, their thinking is still limited by egocentrism (difficulty seeing things from another's perspective) and a lack of understanding of conservation (the principle that quantity remains the same despite changes in appearance).
