Photos taken during a trip or a snapshot with loved ones can linger in memory for a long time. But have you ever wondered why?
We unravel how photos are etched into our memory from a scientific perspective using keywords like 'surprise', 'complexity', and 'the role of emotions'.
Images with Surprise Trigger Alertness
One reason photos remain memorable is the surprise or unpredictability when viewing the image. According to research from Yale University, our brains have evolved to recognize and remember surprises or anomalies.
For instance, a photo of a fire hydrant in the mountains leaves a strong impression due to its unexpectedness. Unfamiliar scenes in daily life are particularly memorable. It's believed that our brains evolved this way to increase survival chances by being alert to unpredictable events.

Complex Information Processing Engages the Brain
Next, the complexity of information is deeply related to memory. The more complex the information, the more the brain tries to understand it, making it easier to remember.
Simple photos are understood at a glance, so the brain doesn't process them further and quickly forgets. However, complex images contain a lot of information, requiring the brain to work actively to interpret them. As a result, such photos remain in memory longer.
For example, compare a street scene photo with an art piece photo. The street scene is simple and contains many familiar elements, so the brain processes it instantly. In contrast, an art piece photo with complex colors, composition, and themes requires the brain to use more resources to understand it, making it more memorable.

Context that Evokes Emotions
Finally, the importance of emotional evocation and context is also cited as reasons why photos remain memorable. Images strongly tied to emotions are easier to remember.
Photos that stir emotions, such as sad news photos or moving landscape photos, are remembered along with those strong emotions. Emotions are elements that enhance memory, and emotional experiences tend to be remembered for a long time.

Furthermore, the background and context are important for making photos memorable. If a photo symbolizes something or is tied to a specific event or experience, it is more likely to be remembered.
For example, photos taken during a special trip or a snapshot with loved ones hold more meaning than just an image, and that context strengthens memory. When capturing memories with family or friends, considering the emotions and context of the moment can help take more memorable photos. In business scenes, creating visual content with awareness of emotions and context is important to leave a strong impression on customers.
Utilize visual information that considers surprise, emotions, and complexity to create memorable moments and convey important messages effectively. By leveraging visual impact, you can engrave your message more deeply in the hearts of others.
