This experiment was performed to find out if memory retention can be improved by reading words out loud as compared to just looking at, and reading flash cards. It is intended to show that students who are actively involved in the classroom discussions learn and retain more information as compared to their passive, non-participating peers.
Reading words on flash cards out loud will help a person remember the word better, as compared to just looking and reading the cards silently.
Memory is defined as the ability of a person to remember and recall information. There are two types of memory - short term and long term memory.
Short term memory is one's ability to remember something that happened recently, like what we had for lunch, or recognizing someone we met yesterday. This memory will be retained for a short period.
Long term memories such as scenes from our childhood days or our job skills, are retained for a very long time.
Having enough sleep helps to improve our memory. Although we are resting, our brains are consolidating the information, making meaningful connections between the information that we have gathered. This way, we are able to recall what we have learnt better.
Another memory enhancing factor is emotion. Extremely good/happy emotions, such as the joy that we would experience if we were to win a lottery or extremely bad emotions, like a traumatic accident are not easily forgotten. Emotion-related events are hard to forget, especially so when the emotions you experience are strong.
The materials required for the experiment:
- 20 boys and 20 girls age between 12 to 15 years
- 20 flash cards
- 40 recall sheets
The result shows that reading the words out loud help a person retain the memory better than just looking and reading silently.
After viewing the flash cards for 5 seconds, boys were able to recall an average of 54.5% of all of the flash cards and the girls were able to recall 45.5% of the flash cards. Reading the cards out loud has helped the boys to improve the percentage of cards remembered to 81.5% and the girls were able to remember 80.0% of the cards.
The hypothesis that reading words out loud helps a person remember better as compared to reading the words on flash cards silently, is proven to be true. The act of speaking the words out loud involves active participation and results in improved memory retention of the participants.
An good memory is beneficial to the process of learning. In addition, it also helps us recognize and recall facts, such as facts about our friends and family. There are many techniques available for memory improvement. For example repeating a person's name many times will help you to remember the names of new people that you meet, or creating stories, sentences or jokes to create linkages between items/people or things that we want to remember. Visualizing (creating a picture in our mind about the things we want to remember) is another technique that you can try.
The experiment can also be done using 10 different three dimensional objects instead of flash cards.
Repeat this experiment with more rest time in between. Is there an ideal rest period for optimal recollection?
How about long-term memory? Ask participants to recall information after a few days. How will the results differ?
