Innovative Method for Measuring Memory Using Eye Movements

A recent study conducted by Tel Aviv University has introduced an innovative method for measuring memory through eye movement tracking. This technique can reveal stored memories even when individuals claim they do not remember. It has proven effective in assessing memory in people unable to communicate verbally, such as infants and patients with brain injuries.

Using Eye Movements to Detect Hidden Memories

The study involved 145 participants who watched videos containing unexpected events, like a mouse suddenly appearing in a corner of the frame. By tracking eye movements during a rewatch, it was found that participants subconsciously looked towards the location of the surprising event from the first viewing.

This discovery suggests that memory can be stored in unconscious ways, as the direction of gaze can indicate the presence of a memory even when the person cannot verbally recall the event.

Clinical Potential of Eye Movement Tracking

One of the most significant aspects of this study is its clinical potential. This method can be used to assess memory in groups with verbal communication difficulties, such as infants and patients with Alzheimer’s or brain injuries. Eye movements can provide an accurate indicator of memory status without the need for verbal interaction.

This method could also be beneficial in future research on how sleep or other factors affect memory, opening new avenues for a deeper understanding of memory mechanisms in the brain.

Modern Technologies and AI Applications

The study utilized artificial intelligence technologies to analyze eye movement data with high precision. These technologies can predict the presence of memory by analyzing gaze patterns in just a few seconds, enhancing the ability to detect stored memories.

Moreover, the use of simple cameras integrated into smart devices makes this technology more accessible, allowing it to be easily used in clinical settings or even at home.

Conclusion

The study represents a significant advancement in understanding human memory, offering a novel and unconventional method for measuring memory without the need for verbal interaction. With the continuous development of artificial intelligence technologies, it is likely that we will see broader applications of this method in the future, both in scientific research and clinical applications.
