Teacher training wouldn't get you anywhere near Steven Pinker,
revel. He is a Psycholinguist (what is that?...a linguist who is psycho?) who specializes in how children acquire language. He has written several popular books (which may be why our friend JuanTwoThree looks askance at him, but he is an acknowledged first-rate scientist) on a variety of related subjects, including language and how the brain works. He also is an active participant in the "nature/nurture" debate, taking neither side exclusively, but delighting in debunking bogus arguments, sometimes from famous scientists.
At any rate, your exercise is not what Pinker calls a "wug test." The
wug test is something Pinker points to which was invented by the psychologist, Jean Berko Gleason, who worked with children in the late 1950's to show one example of how they intuitively grasp the grammatical concepts of (English, in this example, but any native language, according to Pinker) without being told or trained in any way.
Nouns, in English, have two forms: singular and plural; and verbs have two tenses: present and past. Many nouns have an irregular plural just as we have irregular verbs: tooth

teeth, child

children, and so on. Pinker explained in his book,
Words and Rules, that our brains apparently first check an internal list, when the necessity arises for us to produce a plural form, to see if the word in question has an irregular form. The rule is: "If the word is on the list, use the irregular form from the list. If not, add -
s (or its equivalent)." Children, of course, are not taught this rule, but they know it anyway, apparently from observation of how the language works. If you ask a child (and Berko Gleason did ask many) to complete the following:
This is a wug.
Here is another one.
Now there are two ___.
...they invariably complete the sentence with "
wugs". This may seem simple to you and me, but it shows quite a lot. The children (4-7 year olds) might have refused to answer on the grounds that they've never heard of a wug, and so didn't know how to talk about more than one of them. Instead, they confidently, and insistently gave the answer "
wugs". Similarly, they also knew how to make a past tense of verbs they had never heard of because the rule is the same (check the list for irregulars, otherwise add -
ed). So, for children, if you
bling something today, and you did it yesterday too, then you
blinged it. This is not something they could have heard from their parents or other people, but they were confident their answers were right. Somehow, they figured out how to make plurals and past tenses and internalized a rule to guide them. It also explains why children, when they are learning English, so often overapply the rule and come up with, "
Johnny builded a tower from blocks", or "
My daddy flied home from New York last night."
Anyway, that is what a "
wug test" is about.
