- Provides results of a longitudinal study which examined language acquisition in the second year of life in the context of developments in cognition, affect, and social connectedness
- Results of lag sequential analyses are reported to show how different behaviors--words, sentences, emotional expressions, conversational interactions, and construction thematic relations between objects in play--converged, both in the stream of children's actions in everyday events, in real time, an in developmental time between the emergence of words at about 13 months and the transition to simple sentences at about 2 years of age
