Chapter 15: Problem 5

Measure a friend's heart rate. Then have the person think of a terrifying situation. Did the heart rate increase? Choose another person and measure his or her heart rate. Have the person think of a peaceful, calming situation. Did the heart rate decrease? Summarize your findings.

Short Answer

Expert verified
In general, heart rates tend to increase when an individual is experiencing fear or excitement, and decrease when the individual is calm or at peace. However, results may vary from individual to individual.

Step by step solution

01

Measuring Heart Rate

Begin by measuring the resting heart rate of the individual. This can be done by checking their pulse either on the wrist or neck for 60 seconds.
02

Inducing Fear or Excitement

Have the individual think of a terrifying situation. Allow them to sit in this state for a few minutes and then measure their heart rate again in the same manner as in Step 1.
03

Comparing Heart Rates

Compare the heart rate measured in Step 1 to that of Step 2. This will show if the heart rate has increased due to the terrifying situation.
04

Measuring Heart Rate of another Individual

Repeat Step 1 with a second individual, recording the resting heart rate.
05

Inducing Peaceful Emotions

Have this second individual think of a calming, peaceful situation. After a few minutes, measure their heart rate again.
06

Comparing Heart Rates

Compare the resting heart rate measured in Step 4 to the heart rate after thinking of the peaceful situation. This will show if the heart rate has decreased.
