Why Is Yawning Contagious?

The video explores contagious yawning, a phenomenon where yawning spreads among individuals. It discusses various hypotheses, including empathy and mirror neurons, as potential explanations. Studies show that social animals like humans and chimpanzees exhibit contagious yawning, possibly linked to empathy. However, recent research suggests motor neuron excitability might also play a role. The video concludes by highlighting the complexity of this behavior and suggests further exploration of related topics.

What is one hypothesis about why contagious yawning occurs?

• It is a sign of hunger.

• It is related to empathy and social bonding.

• It is a way to cool the brain.

• It is a response to boredom.

Which group of people is less likely to experience contagious yawning?

• Elderly individuals

• Teenagers

• People with impaired social skills

• Athletes

What role do mirror neurons potentially play in contagious yawning?

• They are responsible for memory recall.

• They help regulate sleep patterns.

• They control facial expressions.

• They mirror actions and may aid in mimicry and empathy.

What technique was used to measure motor neuron excitability in the study?

• Electroencephalography (EEG)

• Transcranial Magnetic Stimulation (TMS)

• Functional Magnetic Resonance Imaging (fMRI)

• Positron Emission Tomography (PET)

According to the research, what factor is more related to the likelihood of yawning?

• Time of day

• Amount of sleep

• Age of the individual

• Empathy levels
