"The Psychological Roots of Disgusting Memories Unveiled by Scientists"

Psychologists have found that our most disgusting memories are often associated with smells, tastes, and touches, as these sensory cues elicit disgust more intensely than what we see or hear. This is believed to help protect us from disease by motivating avoidance of potential sources of infection. The emotion of disgust is thought to support our physiological immune system, and the universality of disgust is reflected in widely recognizable facial expressions. The study's findings were published in Royal Society Open Science and suggest that sensory cues of smell, taste, and touch are more intense elicitors of disgust because pathogens and toxins tend to enter the body at these surfaces.
