How infants retain information! NSF Science Now 55

The video covers four NSF-funded studies. The first study, led by Lisa Scott, shows that reading books with specific names enhances infant cognition. The second study reveals that noise pollution causes stress in birds, affecting their survival and reproduction. The third study explores rectilinear locomotion in snakes, which could inspire advancements in robotics. The final study uncovers a previously unknown ancient Native American population through DNA analysis, providing insights into their history and heritage.

What was the main finding of the study led by Lisa Scott regarding infant cognitive development?

• Reading books with specific names and labels enhances cognitive development.

• Infants prefer listening to music over reading books.

• Books with animal characters are more engaging for infants.

• Infants learn better with books that have colorful pictures.

What was the unexpected finding regarding corticosterone levels in birds exposed to noise?

• Corticosterone levels were unaffected by noise.

• Corticosterone levels were higher than expected.

• Corticosterone levels were lower than expected.

• Corticosterone levels increased with noise exposure.

How do snakes achieve rectilinear locomotion?

• By jumping short distances.

• By using their belly scales for traction.

• By moving in a zigzag pattern.

• By sliding on their sides.

What potential application does the study of snake locomotion have?

• Designing better snake-proof fences.

• Developing snake-like robots for search and rescue.

• Creating new types of snake enclosures.

• Improving snake habitats in the wild.

What did the DNA analysis of the ancient Native American remains reveal?

• The remains were from a group that migrated from Europe.

• The remains belonged to a previously known population.

• The remains were from a previously unknown population.

• The remains were unrelated to any known Native American groups.

What is the significance of the discovery of the Ancient Virinians?

• They were the first humans to reach South America.

• They were known for their advanced architectural skills.

• They were the first to domesticate animals in North America.

• They provide insight into the migration patterns of Native Americans.

What was the relationship between the two Ice Age infants discovered at the Upward Sun River site?

• They were parent and child.

• They were likely cousins.

• They were unrelated.

• They were siblings.
