Understanding Primate Research and Human Cognition

Laura Santos, a psychology professor at Yale, studies primates to understand human behavior. She focuses on capuchin monkeys to explore cognitive capacities like theory of mind, comparing them to human infants. Her research also examines economic biases in monkeys, revealing similarities with human financial behavior. Santos highlights the unique human motivation to share information, contrasting it with primate communication.

Why does Laura Santos prefer studying primates over humans to understand human behavior?

• Humans have too many cultural and educational influences.

• Primates are easier to control in experiments.

• Primates are more intelligent than humans.

• Humans and primates have identical behaviors.

What is a key reason for comparing primates with human infants in research?

• Infants lack experience with human-specific technologies.

• Primates can learn languages like infants.

• Infants and primates have similar physical abilities.

• Infants and primates have the same lifespan.

What is the 'theory of mind' as discussed in the research?

• The talent for solving complex puzzles.

• The skill of communicating through language.

• The ability to use tools effectively.

• The capacity to understand others' mental states.

How do researchers test if primates have a theory of mind?

• By observing their tool-making skills.

• By setting up scenarios to test their ability to deceive.

• By comparing their social structures to humans.

• By teaching them to use smartphones.

What is considered a uniquely human trait according to the research?

• The capacity to live in large social groups.

• The skill of hunting in packs.

• The ability to use complex tools.

• The motivation to share information with others.

Why do primates lack the same communication abilities as humans?

• They lack the motivation to share information.

• They do not have the physical ability to speak.

• They are not exposed to human languages.

• They have smaller brains than humans.

What economic concept was tested on primates in the research?

• Market competition.

• Inflation rates.

• Supply and demand.

• Loss aversion.

How did researchers introduce a currency system to the monkeys?

• By using colored stones as currency.

• By using digital tokens on a screen.

• By giving them metal washers to trade for food.

• By teaching them to recognize paper money.

What behavior did monkeys exhibit that showed loss aversion?

• They preferred traders who gave them more than expected.

• They avoided traders who gave them less than expected.

• They ignored all traders and kept their tokens.

• They chose traders based on the color of their clothes.

What does the research suggest about the age of economic biases like loss aversion?

• They are unique to modern humans.

• They are a recent development in human history.

• They might be as old as 35 million years.

• They only developed after the invention of money.
