Eye Tracking Could be Biomarker for Brain Function and Brain Injury
The location and impact of a brain injury can be assessed merely by tracking eye movements of patients as they watch music videos for less than four minutes. This is possible with a new technology.

‘Eye tracking (ET) could now be used to measure receptive vocabulary in children with motor delays, according to a new study.’

In conducting the study, a Tobii Pro X3-120 eye tracker was used with Tobii studio software to present stimuli and collect data on recruited patients, aged 18 months to six years. Participants first completed calibration to measure participant-specific gaze data. Participants were then presented with a stimulus of a target image alongside a distracter, accompanied by audio instructions to direct their gaze at the target. Stimuli were derived from standardized developmental assessments. Word comprehension was measured as accuracy and fixation proportion.The study found that ET is feasible in young TD pediatric patients and those with marked ELDs. Word comprehension as measured by accuracy significantly increases as a function for normal development. Accuracy in children with expressive language delay (ELD) is significantly lower compared to TD children of the same age, suggesting a more diffuse cognitive impairment.
"The goal of the study was to evaluate eye tracking as a tool for measuring receptive language ability in pediatric patients," said Dr. Mary Vernov, one of the authors of the study. "Findings show that eye tracking can be explored as a modality for assessing receptive language in children. This has important implications for evaluating children with developmental delays and may be used as an alternative form of communication in those with expressive language delays."
Concussions can be Detected Accurately by Eye Tracking
A new eye tracking technique was presented by researchers at the NYU Langone Medical Center which has better potential than CT scan.

Motherese: Early Conversations of Mother to Child
Motherese, a special speech and language pattern adopted by people when talking to infants and small children, helps the child in language acquisition. Other terms used are child-directed speech, parentese and caregiver speech.
