We all know that hysterical feeling when someone tickles us, but it's a whole different story if you try to do it yourself. Why is it so hard to tickle yourself?

  1. There is no unease or tension

  2. Our cerebellums automatically distinguish expected versus unexpected sensations

  3. Both are correct.

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The inability to tickle yourself is due to the cerebellum's predictive function - it anticipates the sensory consequences of your own movements and dampens the response. This means when you try to tickle yourself, your brain predicts exactly what will happen, eliminating the element of surprise that causes tickling. The absence of unease or tension is also relevant since tickling often involves surprise from unexpected touch.

B Correct answer
Explanation

Research studies have found that the average adult laughs approximately 15-20 times per day, with 17 being a commonly cited statistic in psychological research. Children laugh much more frequently (up to 400 times daily), while adults laugh less frequently. Laughter frequency decreases with age, making this a notable difference between adults and children.

B Correct answer
Explanation

Laughter has multiple beneficial effects on the body including increased blood flow, increased antibody production, and stress reduction. However, difficulty sleeping is NOT a normal result of hearty laughter - in fact, laughter tends to promote relaxation and better sleep quality by reducing stress hormones. The other three options are all documented positive physiological effects of laughter.

Which of the following is a fair representation of the relationship between laughing and exercise?

  1. laughing once = 15 minutes of exercise on a bike

  2. laughing 10 times = 15 minutes of exercise on a bike

  3. laughing 100 times = 15 minutes of exercise on a bike

  4. laughing 125 times = 15 minutes of exercise on a bike

C Correct answer
Explanation

Research in gelotology suggests that laughing 100 times provides cardiovascular benefits roughly equivalent to 15 minutes of exercise on a stationary bicycle. This comparison is based on heart rate and oxygen consumption studies during laughter.

  1. It depends on the strength of your immune system.

  2. yes

  3. no

  4. your will power decides it

This is different from contagious laughter (everyone laughing simultaneously) or laughter that interrupts speech flow.

Scientists have successfully pinpointed laughter in which region of the brain?

  1. the frontal lobe

  2. the limbic system

  3. Research has found that brain activity during laughter expands across multiple regions of the brain.

  4. the temporal lobe
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Laughter is a complex neural activity involving multiple brain regions, not localized to a single area. Research shows that laughter activates areas throughout the brain including the frontal lobe, limbic system, and temporal lobe, working together in a coordinated network. The frontal lobe processes the humorous stimulus, the limbic system generates the emotional response, and various motor regions control the physical act of laughing.
