TPO43L2 Approximate Number Sense (Psychology)



1.What is the main purpose of the lecture?

A. To explain a mechanism behind the ability to approximate numbers

B. To explore the connection between ability in symbolic mathematics and the ability to approximate numbers

C. To show the importance of new research into the ability to solve complex mathematical problems

D. To demonstrate that children, adults, and animals have a similar ability to approximate numbers


2.Why does the professor mention six-month-old infants?

A. To emphasize that ANS is largely innate

B. To refute the claim that symbolic mathematics is learned

C. To point out the difficulty of testing mathematics ability in very young children

D. To contrast the way infants learn with how older children learn


3.Why does the professor stress that the dots in the experiment flashed on the computer screen for only a fraction of a second?

A. To emphasize that humans’ ANS ability is more developed than that of animals

B. To point out that it was not possible to complete the task using formal mathematics

C. To show a contrast between the dot experiment and the color-naming experiment

D. To explain, in part, how subjects were chosen for the experiment


4.What did researchers observe in the study of fourteen-year-old children?

A. The children with strong ANS skills also scored well on color-naming tests

B. The children were more likely to make mistakes when there were small numbers of blue and yellow dots 

C. The ANS skills of the children had improved over time.

D. There were large differences in the ANS skills of the children tested.


5.Why does the professor mention that the subjects of the experiment were also tested in reading and word knowledge?

A. To show that ANS skills are not linked with abilities in those areas

B. To emphasize the thoroughness of the researchers

C. To point out that ANS and other skills are learned in a similar way

D. To contrast learned skills with innate abilities


6.What is the professor’s opinion of using instruction in ANS to improve children’s performance in formal mathematics?

A. It is likely that instruction in ANS would lead to improvement in areas other than formal mathematics.

B. It would be important for the instruction in ANS to begin when children are very young.

C. It is unclear whether instruction in ANS would improve performance in formal mathematics.

D. it is more likely that instruction in formal mathematics would improve children’s ANS ability.
