Children remember nothing but happy times?

(parents can take time to play and chat with their 5-month-old baby may wonder, can they remember anything the next day?

According to a new BYU study, at least children can remember happy times. This study is presented in the journal Infant Behavior and Development, which shows that children tend to remember what it is if it comes with an emotion or a positive impact. pole.

"Scientists study children's memory, they study the difference in emotional impact , but we are the first scientists to study whether those emotions affect memory like that. " , BYU psychology professor Ross Flom, the study's lead author said.

Although 5-month children are unable to speak, there are many different ways for researchers to analyze how babies respond to test methods. In this study, they observed the movements of their eyes and how long they looked at the test image.

Babies are seated in front of a flat screen in a closed room and then exposed to a person on the screen talking to them in a cheerful, normal or angry voice. Immediately after being exposed to emotions, the children showed two types of charts.

To test their memory, the researchers performed the test 5 minutes later and repeated it one day later. In the next test, the children showed two types of charts: a new form and an initial form from the study.

Researchers were then able to record how many times babies looked from one image to the next and how long they spent looking at each image.Children's memory does not improve if the shape is accompanied by a negative voice, but they can remember significantly better when the image appears with a happy and happy voice.

"We think that what's going on has affected the nervous system, increasing the concentration and excitement of babies," Flom said. "By enhancing these systems, we can improve processing capabilities and perhaps remember this geometric model."

The study was conducted by co-authors with Professor Brock Kirwan, as well as graduate students and master's students Rebecca B. Janis and Darren J. Garcia. This study follows Flom's series of important studies on the ability to understand each other's mood in babies, the mood of dogs, monkeys, and their ability to understand classical music.
