Eyes Tracking

When people talk about eye tracking behavior, they're usually referring to what is called smooth pursuit eye movement, or the eyes' ability to follow a moving object. A number of regions in different parts of the brain work together to accomplish smooth pursuit eye movement, which means that this skill can be disrupted by a variety of disorders affecting the brain. Eye tracking studies have found a correlation between smooth pursuit eye movement and conditions like schizophrenia, autism, post-traumatic stress disorder, and drug and alcohol intoxication.

Researchers have found evidence that eye tracking behavior is deficient in people with schizophrenia and their relatives. Specifically, schizophrenic patients seem to have difficulty tracking fast-moving targets and those that move in a predictable way. Object that move unexpectedly seem to be easier for schizophrenic people to track.

In addition to having potential as a diagnostic aid, looking at eye tracking behavior can help identify people who may be at a risk for developing schizophrenia. A study published in 2007, by professor Mark F. Lenzenweger, outlined what appeared to be a successful way to predict the probability a person will develop schizophrenia by looking at the person's eye tracking behavior and ability to sustain attention. Eye tracking studies continue to be used frequently in research conducted into schizophrenia and other mental conditions, offering additional insight into the brain’s behavior and providing a way to classify individuals into at risk and not at risk groups.
