Researchers from the University of Basel in Switzerland have published a new study in the international academic journalneuron, which demonstrates how memory affects people’s choice of food through magnetic resonance imaging.
When choosing food, the more we remember about a food, even if it doesn’t have anything special, we might still choose it. Scientists from the University of Basel have answered the question of how memory affects food choices. They conduct scientific research by providing different foods combined with brain activity scans. They found that the effect of memory on food choices was achieved by increasing the exchange of information between different parts of the brain.
In the study, the researchers selected 3,000 young people to rate 48 small snacks, including potato chips, chocolate bars, pretzels, and soft-flavored foods to satisfy different tastes. demand. The researchers showed a variety of small snacks on the computer, each of which had a specific location, and then they scanned the subjects for MRI and asked them to repeat between the two snacks, and only In this way, the researchers showed the subjects to associate the snacks with the location for recall. The results showed that volunteers were more inclined to choose a snack that they could remember more clearly, only a small number of extremely unattractive foods, and volunteers would not choose even if they remember clearly. In the control group, the researchers directly displayed the food pictures on the screen, and the subjects’ selection of various foods was basically the same as the initial score.
The research team used magnetic resonance functional imaging to study the neurobiological mechanisms based on memory selection, and developed a computational model that presents the decision process and the impact of memory on decisions. This study links psychology to neurobiology and is important for interdisciplinary research in psychology and neurobiology.
