Peer Influence on Risk-Taking Behavior

The video discusses a study on peer effects in risk-taking and decision-making. Participants, including teenagers, college students, and adults, were tested alone and with friends watching. Results showed that peer presence increased risk-taking in adolescents and college students but not adults. An FMRI experiment revealed that peers activate reward circuits in teenagers' brains, influencing their decisions. A delay discounting task showed that 19-year-olds with peers made decisions like 14-year-olds. The study highlights the significant impact of peers on adolescent behavior and brain activity.

What was the main finding regarding adolescents' risk-taking behavior when peers were present?

• Adolescents took fewer risks.

• Adolescents' risk-taking doubled.

• Adolescents took no risks at all.

• Adolescents' risk-taking remained the same.

How did the presence of peers affect college students' risk-taking behavior?

• It doubled their risk-taking.

• It had no effect.

• It increased risk-taking by 50%.

• It decreased their risk-taking.

What did the fMRI experiment reveal about adolescents' brain activity?

• Peers had no effect on brain activity.

• Peers decreased brain activity in adolescents.

• Peers activated reward circuits in adults.

• Peers activated reward circuits in adolescents.

Why do researchers believe adolescents take more risks with peers?

• Peers have no influence on decision-making.

• Peers decrease the salience of risks.

• Peers increase the salience of rewards.

• Peers encourage risk-taking directly.

What task was used to measure preferences for immediate versus delayed rewards?

• Memory recall task

• Risk assessment task

• Delay discounting task

• Problem-solving task

How did 19-year-olds behave in the delay discounting task with peers watching?

• Like adults

• Like 14-year-olds

• Like college students

• Like 10-year-olds

What was the behavior of 19-year-olds in the delay discounting task without peers?

• They behaved like 14-year-olds.

• They preferred immediate rewards.

• They behaved like adults.

• They took more risks.

What was the researchers' reaction to the initial brain scan results?

• They were skeptical.

• They were disappointed.

• They were indifferent.

• They were excited.

What did the researchers find amazing about their experiment?

• The results were inconsistent.

• The results were too good to be true.

• The results were inconclusive.

• The results were disappointing.

What is the significance of the research findings?

• They have no practical implications.

• They help understand adult risk-taking.

• They provide insights into adolescent risk-taking.

• They suggest peers have no influence.
