Blue Light and Emotional Response

Medium
Blue Light and Emotional Response | Science Fair Projects | STEM Projects
Can the color of light in a room change how strongly you react to an emotional scene? Studies show that different parts of the light spectrum affect mood and well-being in different ways. You divide 20 participants into two groups. One group watches a sad movie scene in a room lit by blue light. The other watches the same scene under normal white light. Before and after viewing, each person rates their emotional state on a 1 to 3 scale. Compare the before-and-after ratings to see whether blue light amplifies or dulls the emotional response.

Hypothesis

The hypothesis is that blue light has an effect on how our brains process emotions.

Method & Materials

You will divide participants into two groups, one that will be tested with blue light and one with regular white light. You will then replace the light bulbs in the room with blue light bulbs and have the participants view emotional scenes from a movie. After viewing the scenes, the participants will rate their emotional well-being on a scale of 1-3.
You will need 20 participants, a room with adequate indoor lighting, a supply of blue light bulbs, emotional scenes from a movie, and a data sheet.

Results

The experiment showed that blue light had an effect on how the participants processed emotions. The results showed that the participants who were exposed to blue light had a higher emotional rating than those who were exposed to regular white light.

Why do this project?

This science project is interesting because it explores the potential effects of blue light on the human brain, which has not been studied in depth before.

Also Consider

Variations of this experiment could include testing different colors of light or testing different types of emotional scenes.
