ABSTRACT
When male adolescents were unknowingly placed in an isolated environment with an attractive woman, there wasn’t enough viable data to determine whether or not their blood pressure increased. Based on our limited and unreliable data there is no significant increase in the heart rate or blood pressure of male adolescents when placed in this situation.
INTRODUCTION
As blood flows through all parts of the body, it exerts a pressure on the walls of the arteries carrying it. Blood pressure reflects this force through two numbers, the systolic and the diastolic.

METHODS AND PROCEDURES
We began this lab by setting up a testing area in the back room of the laboratory. This was necessary in order to isolate the test subjects from the rest of the class and any other possible distractions. We then took freshman and sophomore boys one by one into the testing area to take their blood pressure and heart rate. This was done while they were asked a series of questions, however we were careful to stay professional and uninvolved with conversation. Next we left the room under the pretense of having other matters to attend to, and an attractive woman came in to take their blood pressure and heart rate while asking the exact same questions as well as acting flirtatious. We then compared the blood pressures and heart rates of the students that were taken by us with those taken by Shaylyn.

RESULTS
Even though there was no statistically significant (P<0.05) difference between the blood pressures and heart rates of underclass males when talking to us, and when talking to Shaylyn, there were minor increases in the blood pressure of all the test subjects. There was a 16% increase in the systolic and a 10% increase in the diastolic blood pressures of the test subjects when Shaylyn took their blood pressure. However, there was also a 43% decrease in the heart rates of the 3 students.
