Question

Conduct the following experiment and find out whether the color of text has any impact on memory:

1. Randomly assign participants to two groups. (See to it that age, gender, cultural background, etc. of all participants is same.)
2. Ask one group to read a list of 20 words written in black ink for 5 minutes.
3. Ask the second group to read a list of the same 20 words for the same amount of time, but instead written in green ink.
4. After 5 minutes, ask participants from both the group to write down as many words as they can recall on a plain paper.
5. Compare the recall scores and conclude.

Answer 1

Experiment: Effect of Text Colour on Memory

Aim:

To find out whether the colour of text has any impact on memory.

Procedure:

1. Randomly divide the participants into two groups while keeping factors such as age, gender and cultural background similar.
2. Give the first group a list of 20 words written in black ink and ask them to study it for 5 minutes.
3. Give the second group the same 20 words written in green ink and allow them the same 5 minutes to study.
4. After 5 minutes, ask participants in both groups to write down as many words as they can remember on a plain sheet of paper.
5. Count the number of correctly recalled words for each participant.
6. Compare the average recall scores of the two groups.

Conclusion:

If the green-ink group recalls significantly more or fewer words than the black-ink group, it suggests that text colour may have an impact on memory. If the scores are similar, text colour may have little or no significant effect on memory.
