Okay, so this one is asking us, which of the following is not a critique of Piaget's theory of cognitive development? We will just run through them, we will note all of the critiques, and we will find the one that is not a critique. So a says the theory places inaccurate age boundaries on many of the proposed milestones, and that is a critique of Piaget's theory. Some of the ages that he proposed were just kind of wildly inaccurate based on what we know now. So that is indeed a critique of his theory.

B says that the theory fails to account for social influences on development and that is also a critique of Piaget's theory. He really did not take into account how individual differences, social factors, and cultural factors can potentially speed up or slow down some of these milestones. So that is a critique of his theory. C is that stage theories are now considered outdated due to their overly rigid nature. That is also true and that is a critique of this theory.

We no longer really like stage theories. They're way too rigid. They place very strict boundaries and, like, age limits on things, and that's just not how development works. We now take a more continuous model approach to development, more commonly. And then we're left with D, which is that concepts like conservation and egocentrism are not supported by modern research, and that is not true.

Concepts like conservation and egocentrism are actually very well supported by modern research, and we actually research those topics all the time to this day. So he was kind of spot on with those. Alright. So our answer here is D, that is not a critique of Piaget's theory, and I will see you guys in our next one. Bye bye.
