Can eye tracking be used on infants?
Eye tracking data can help explore infants’ ability to categorize visual, linguistic, and auditory events, and scan dynamic human faces. Among older children and adolescents, researchers study cognitive processes like executive function and social interaction.
When should my baby start tracking with his eyes?
Eye Coordination and Tracking A baby should begin to follow moving objects with the eyes and reach for things at around four months of age.
How does eye tracking relate to attention?
Most importantly, visual eye tracking facilitates the study of visual attention. Due to the limited nature of image processing resources, the brain selectively chooses relevant visual information based on: Interest – the conscious or unconscious decision to look at an object.
How do scientists measure attention in infants?
Research Context Infant attention is measured in the laboratory using looking time, heart rate, and the electroencephalogram (EEG). Infant heart rate shows a sustained decrease during periods of attention, triggered by activity within the brain stem.
When do babies start tracking faces?
By the end of 3 months, they can follow a moving object, are more interested in shapes and patterns, and can spot familiar faces, even at a distance. Human faces are one of their favorite things to look at, especially their own or a parent’s face.
What is normal eye movement for a newborn?
At birth, a newborn’s eyesight is between 20/200 and 20/400. Their eyes are sensitive to bright light, so they’re more likely to open their eyes in low light. Don’t worry if your baby’s eyes sometimes cross or drift outward (go “wall-eyed”). This is normal until your baby’s vision improves and eye muscles strengthen.
When do babies start recognizing faces?
Studies have shown that even newborns, with their eyesight limited to about 12 inches, prefer to look at familiar faces — especially yours. Months 2 to 4: Your baby will start to recognize her primary caregivers’ faces, and by the 4-month mark, she’ll recognize familiar faces and objects from a distance.
What is infant attention?
Infants pay attention by turning to sounds or by looking at things. Younger infants look longer than older infants because it takes them longer to “encode” the object mentally.
What are the stages of infant attention development?
During the course of a single look, infants will cycle through four phases of attention—stimulus orienting, sustained attention, pre-attention termination, and attention termination.
