Head-turn Preference Procedure

We use a 3-side booth, with side lights close to loudspeakers and a central light. The child looks at the central light. Then one of the side lights starts blinking and as soon as the child looks at it a sound sequence starts to play. We measure the time the child is oriented to the side light, and is listening to the sound, as an indication of preference for a given type of sound sequence.
