Children’s negation is not similar to adults especially in the first years of life.
Topics, as Pea calls them, are not represented in the same manner.
He describes an example by Volterra and Antinucci (1978): Child looks at hospital tower and says “Look, there is no bell”
Adults know that church towers have bells, not hospital towers and are not surprised when it is not there.
In their view, the child aligns their representation of the topic with the adult’s or listener’s. How???
