Well, Columbus never actually came to America. His ship made land in the Bahamas and Cuba. He thought these islands were Asian islands because the people of Spain were unaware of the Americas, and so he wanted gold. He returned to his country and came back with more men. And killed a lot of people.
Anyway, for the sake of the American education system, I'm assuming the word the teacher is wanting is something like "recognized".
Their research shows that: people can easily develop superstitious behaviors without<span> even being aware of it
In the experiments, the students were given 5 cent if they pressed correct number of key from 4 buttons (the only button that matter is number 3)
But instead just pressing the one correct number, the students keep pressing all buttons because they develop superstition that pressing all buttons are necessary.</span>
