Influence of Environmental Light on Reaction Time

Overview

Objectives/Goals Daytime driving is generally safer than driving at night due to an abundance of light. The purpose of this project is to test if there is a relationship between the intensity of light and the reaction time of drivers. Methods/Materials 1. 1 meter stick 2. Lux meter 3. Night light 4. Volunteers 5. Notebook 6. Computer 7. Pencil Results Based on the graph, fifty-five percent had faster reaction time in sunlight and thirty-five percent had faster reaction time in dim light. Meanwhile, the intensity of light did not affect the reaction time for ten percent of the subjects. Conclusions/Discussion My hypothesis was correct. I was not surprised that fifty-five percent of my test subjects had faster reaction time in sunlight. Due to the lack of visibility, the test subjects had a slower reaction in dim light then sunlight. Based on the results, it would be advisable for car manufacturers to consider the findings of this project to modify existing headlights.
