Early Communicative Gestures in Infancy
Infants use gestures to communicate long before they can speak, demonstrating emerging cognitive and communicative abilities. For example, infants typically shake their head "no" around 6–9 months of age. By 9–12 months, they respond to verbal requests to perform actions such as "wave bye-bye" or "blow a kiss". Furthermore, research suggests that the use and development of these early gestures in infancy can predict the timeline and course of subsequent language development.

Interactionist View of Language Acquisition
A developmental psychologist observes that children from vastly different cultural and linguistic backgrounds (e.g., urban Japan, rural Peru, and suburban Canada) all begin to babble, use single words, and then combine words into simple sentences at roughly the same ages. This cross-cultural consistency, despite significant differences in their environments and the specific languages they are exposed to, provides the strongest support for which of the following perspectives on language acquisition?
