Language development

    In the previous chapter, on infant language development, you learned about the stages of language development, theories about the genetic basis of  language, and the importance of the environment. (Click here if you would like to go back to those pages and review that information.) There are other common characteristics of children's language development, in addition to the stages. These include:
 

The preoperational stage and characteristics thereof:
(Very briefly, since this is covered in your textbook)

What are operations? What is he talking about? Maybe Piaget is more easily comprehended in the original French. Unfortunately, I don't read French, do you? Fortunately, you have me, your humble instructor here at your service to (hopefully) make this somewhat clearer than mud.

An example might help...
 
 
 
AN EXAMPLE OF A CHILD AT THE PREOPERATIONAL STAGE, 
I.E., ONE WHO DOES NOT  ENGAGE IN MENTAL OPERATIONS
This is Maria at age five, a very bright little girl. I tried the pennies exercise with her (you know, the one in your textbook). Here is what happened. First, I took a row of ten pennies and evenly spaced them apart.

O  O  O  O  O  O  O  O  O  O 

ME: Now, Maria, look carefully at the row of pennies. There are ten pennies here, right?
MARIA: I don't know, let me see. One, two, three, four, five, six, seven, eight, nine, ten! Yes.
ME: All right, very good counting. Now I am going to do something with them. I am going to spread them out. Then I am going to ask you a question. If you get the right answer, you can keep all ten pennies.

(Notice my clever use of positive reinforcement, in keeping with what theorist - that's right, Skinner.)
Now, I moved the pennies apart further so that they looked like this.

O      O      O       O       O  O      O  O      O       O 

ME: Now, Maria, are there more pennies than there were before, less, or just the same?
MARIA: One, two, three, four, five, six, seven, eight, nine, ten -- there are the same. There were ten before and there are still ten.

Maria takes all the pennies.
 

Why is this preoperational? She got the right answer. Because Maria had to count the pennies to know that they were the same. She could not perform logical operations to come to the right answer.
 


 
 
 
AN EXAMPLE OF A CHILD WHO DOES  ENGAGE IN MENTAL OPERATIONS




The next year, we did the exact same task and the conversation went like this.
 

Again, I took a row of ten pennies and evenly spaced them apart.

O  O  O  O  O  O  O  O  O  O

ME: Now, Maria, look carefully at the row of pennies. There are ten pennies here, right?
MARIA: Okay.
ME: Now I am going to do something with them. I am going to spread them out. Then I am going to ask you a question. If you get the right answer, you can keep all ten pennies.

O      O      O       O       O  O      O  O      O       O

ME: Now, Maria, are there more pennies than there were before, less, or just the same?
MARIA: The same.
ME: How do you know that?
MARIA: Because you didn't take any away and you didn't add any, so there must be the same. Besides,all you did was spread them apart and you could just squish them back up together again.

PAY ATTENTION TO THAT LAST STATEMENT. Although it may not sound so profound, it demonstrates an understanding of the concept of reversibility --- Unlike the year before, she did not need to count the pennies or do anything physical to know that there were the same number of pennies. While a preoperational child could get the correct answer by pushing the pennies back together, a child who has achieved the concrete operational stage can perform this IN HER MIND. That, is, she can know something - in this case, that you can push the pennies back together and have the same appearance as before-  without actually doing it.

Developmental psychologists are in almost universal agreement that Piaget underestimated the cognitive capabilities of young children. As has been pointed out in much of this chapter, children are better than Piaget had thought at understanding causality, other people's points of view and numbers. Your textbook author spends quite a bit of this chapter discussing Wellman's research on theory of the mind, and other studies which seem to document children's ability to understand the world. I am assuming that there is a point to this, rather than just trying to fill up space, and I think the point is that preschool children are quite aware of what is going on around them. SO ... we should:
