Here is a description of the study: In the listening task, Kira was seated on my lap in front of a TV monitor at a distance of about 3 feet on which various displays were presented. First, Kira’s attention was drawn to the screen with a visual display (e.g. a flashing red light). Once she was watching the TV monitor, a visual display (e.g. a picture of a boy with five balloons) was presented on the video monitor accompanied by audio speech stimuli (e.g. Look, he has balloons!). A video camera recorded Kira’s face to determine how much time her gaze was fixated on combinations of video and audio displays. All Kira needed to do was listen to the sounds while watching the display on the TV monitor. These looking time measures provide information about children’s sensitivity to speech stimuli.*
