Transcript of The Effect of Distractions on Reaction Time

This lab tested whether reaction time is affected by distractions. Our hypothesis is if distractions are present in a task, then reaction time is slowed. Participants were high school students whose ages ranged from 17-18. Ten students participated in the test. Each participant did a Reaction Time Test online with a distraction and did the test without any distractions. 80% of participants showed a slowed time of completing the test with distractions present. 20% of participants showed an increased time of completing the test with distractions present. Therefore, the majority of the results (80%) supported the hypothesis. There were students whose results refuted the hypothesis and this may have occurred because the students may have a natural or learned ability to block out distractions when given a task (demonstrate control). The majority of our data supported our claim (80%). The hypothesis, if distractions are present, the the reaction time is slowed is therefore supported.
Do distractions affect a person's reaction time?
In order to test if distractions affect reaction time, we had participants take an online reaction time test using the website, http://getyourwebsitehere.com/jswb/rttest01.html.
The experiment was conducted with 10 students that each participated and took the same test twice. First they took the test without distraction then they took the test with distractions.
Distractions consisted of: playing loud music, yelling, questioning them, clapping, snapping, throwing objects at them and poking.
