Auditory-oral matching behavior in newborns

Twenty-five newborn infants were tested for auditory-oral matching behavior when presented with the consonant sound /m/ and the vowel sound /a/ - a precursor behavior to vocal imitation. Auditory-oral matching behavior by the infant was operationally defined as showing the mouth movement appropriate for producing the model sound just heard (mouth opening for /a/ and mouth clutching for /m/), even when the infant produced no sound herself. With this new dependent measure, the current study is the first to show matching behavior to consonant sounds in newborns: infants showed significantly more instances of mouth opening after /a/ models than after /m/ models, and more instances of mouth clutching after /m/ models than after /a/ models. The results are discussed in the context of theories of active intermodal mapping and innate releasing mechanisms.

Young Children Know That Trying Is Not Pretending: A Test of the "Behaving-As-If" Construal of Children's Early Concept of Pretense

In 3 studies, young children were tested for their understanding of pretend actions. In Studies 1 and 2, pairs of superficially similar behaviors were presented to 26- and 36-month-old children in an imitation game. In one case the behavior was marked as trying (signs of effort), and in the other case as pretending (signs of playfulness). Three-year-olds, and to some degree 2-year-olds, performed the real action themselves (or tried to really perform it) after the trying model, whereas after the pretense model, they only pretended. Study 3 ruled out a simple mimicking explanation by showing that children not only imitated differentially but responded differentially with appropriate productive pretending to pretense models and with appropriate productive tool use to trying models. The findings of the 3 studies demonstrate that by 2 to 3 years of age, children have a concept of pretense as a specific type of intentional activity.
