- A study on students from Brazil, China, Sweden, and the United States was completed.
The basis of the study was to compare how each of the students responded to a two-stage probability problem.
- In each culture, there was a significant tendency for the students to stick with their initial
decision, and they were right. However, there was also a significant tendency for the students to keep their first answer,
even when they should have switched.
- With this type of problem, the four cultures did not differ significantly. Therefore, this
research implies universality in language acquisition, due to the fact that each culture in itself is greatly different from
one another, yet when it comes to problem-solving, and deciding on an answer, the majority of the students all thought alike.
This research also goes along with the idea of the Universal Grammar theory.
