For example, the infant may deliberately communicate with the adult by giving her an object and vocalizing, while the infant's gaze remains directed towards the object.

Vocalizing is a low-cost activity compared to engaging in agonistic encounters with other hummingbirds.
Communication/language behaviors consisted of vocalizing, babbling, and gesture (measured in rate of occurrence).
Occurrences of vocalizing were coded as distinct when they were separated by a pause.

In addition, in order to further characterize infants' reactions, we also coded their looking and vocalizing in relation to their pointing.
Led by neo-avant-garde stars, the students remained firmly in the audience, some of them vocalizing their frustrations.
