Mothers' Contingent Imitation Increases Infant Vocalizations.
Pelaez-Nogueras, Martha; Gewirtz, Jacob L.
This study compared the reinforcement effects of imitation to the elicitation effects of noncontingent maternal vocal stimulation. Subjects were 17 three- to six-month-old infants and their mothers. Infants received three successive experimental conditions: contingent imitation B1, noncontingent elicitations, and contingent imitation B2. Under the contingent imitation conditions mothers imitated the topography of their infants' vocal responses immediately after their emission. Under the noncontingent yoked-control condition, mothers responded in a pattern of duration and topography identical to the previous pattern (B1), but with a pause following the infant vocalization. Analysis showed that 15 of the 17 infants emitted higher vocalization frequencies under the contingent imitation conditions than under the yoked-control condition. It is concluded that mothers' imitative vocal responses can function as effective reinforcers for infant vocalizations. (MM)
