A dynamic network approach to bilingual child data
Usage-based approaches to language acquisition emphasize the central role of input–output relationships in the gradual emergence of linguistic knowledge. Recent computational work has provided empirical support for this view by showing how network-based analyses can capture constructional patterns in child language. One such method is the Dynamic Network Model (DNM). However, it remains unclear whether these findings extend to bilingual acquisiti…
Frequency, redundancy, and context in bilingual acquisition
We report findings from a corpus-based investigation of three young children growing up in German-English bilingual environments ( M = 3;0, Range = 2;3–3;11). Based on 2,146,179 single words and two-word combinations in naturalistic child speech (CS) and child-directed speech (CDS), we assessed the degree to which the frequency distribution of CDS predicted CS usage over time, and systematically identified CS that was over- or underrepresented in…
A dynamic network analysis of emergent grammar
For languages to survive as complex cultural systems, they need to be learnable. According to traditional approaches, learning is made possible by constraining the degrees of freedom in advance of experience and by the construction of complex structure during development. This article explores a third contributor to complexity: namely, the extent to which syntactic structure can be an emergent property of how simpler entities – words – interact w…
The communicative contexts of grammatical aspect use in English
In many of the world's languages grammatical aspect is used to indicate how events unfold over time. In English, activities that are ongoing can be distinguished from those that are completed using the morphological marker - ing . Using naturalistic observations of two children in their third year of life, we quantify the availability and reliability of the imperfective form in the communicative context of the child performing actions. On average…
Little Dictators
Using the dictator game as a measure of prosocial behavior, we combined data from developmental studies from 14 different sites around the world (N = 1,601). We fitted several growth models to the developmental trajectories that varied in their complexity and levels of prosociality. The rationale we used here assumes we can infer something about where all children start on a generous-selfish continuum by looking at the shape of developmental chan…
The attention-grammar interface
We investigated whether children (3- and 4-year-olds) and adults can use the active passive alternation – essentially a choice of subject – in a way that is consistent with the eye-gaze of the speaker. Previous work suggests the function of the subject position can be grounded in attentional mechanisms (Tomlin 1995, 1997). Eye-gaze is one powerful source of directing attention that we know adults and young children are sensitive to; furthermore, …

Urbanization in Southern Rhodesia
When addressing the Congress of the Southern Rhodesia Municipal Association at the Victoria Falls in May 1944, Sir Evelyn Baring, then Governor of Southern Rhodesia, expressed the view that the historian of the future, when he came to write the story of Southern Rhodesia during the present period, would conclude his survey by remarking that the problem of the urban Native was one of the most vital of those which faced the colony during the 1940's…
