A developmental researcher creates a special apparatus that makes it appear to 4-month-old Violet that two different objects are in exactly the same spot at exactly the same time. Violet seems to be quite surprised by what she sees. Given what you have learned about children's early knowledge of scientific phenomena, you would be most likely to conclude that Violet's reaction is:
a. Quite typical for her age-group
b. A bit unusual, as children are usually at least 15 months old before they understand that two objects cannot occupy the same space at the same time
c. Quite unusual, as children are usually at least 5 years old before they understand that two objects cannot occupy the same space at the same time
d. Probably a fluke, as most 4-month-olds have poor visual perception
Question 2
The finding that children whose first language is Chinese learn to count at a younger age than children whose first language is English suggests that:
a. more children in China come from middle-income families than children in the United States.
b. the way that numbers are encoded as words has an effect on certain mathematical skills.
c. mathematical skills are primarily influenced by environment, rather than genetics.
d. children in China are born superior with neurological networks that process mathematical thinking than are children in the United States.
