Abstract
The ability to discover and learn about the consequences of own vocalizations is currently being studied in three groups of infants, 3–5-, 6–8-, and 9–11-month olds, exploring a situation that resembles an audiovisual memory game. The infants are tested individually, in a quiet and dimmed studio. They sit in front of a black computer monitor connected to an eye-tracking system. At randomly selected intervals, a circle appears in the center of the screen and expands and shrinks rapidly to a bright circle to signal that an observation trial is in progress. If the infant vocalizes during the trial, an animated actor emerges after about 200-ms delay at screen coordinates that are contingent on spectral characteristics of the initial part of the infant’s vocalization. The actors brightness and time on display is controlled by the vocalizations overall intensity. By analyzing the changes in predictive looking behavior that probably occur during the session, we expect to gather valuable information on the infant’s capacity to learn about consequences of their vocalizations at different ages.
