A pseudo concept appears to have validity, sometimes.
Pseudo Concept: This is very commonly encountered among young children. In Pseudo Concepts there is a central theme, like in the Associative Complex, but the bond(s) between its members is consistent.
There are, however, typically just a single or a few rather obvious (palpable) bonds. This makes for a situation where the child may appear to have a valid concept, but in reality is still confused.
For me, personally, as a six year old, I recognized a policeman by the visor he wore. And when my Dad pointed to one and asked, "What is that Edward," I appeared to respond knowledgeably. But unfortunately, the milk man, taxi drivers, doormen, soldiers, and half the populous in Hawaii whho had sensitive eyes, wore some kind of visor. I was convinced, unknown to my Dad, that we lived in a police state.
