Traditionally, linguistic variation within different time scales has
been the province of different disciplines, each with a distinctive
suite of techniques for obtaining and analyzing data. For example,
historical linguistics, sociolinguistics and corpus linguistics study
variation between different speaker groups over historical time and
across space, while psycholinguistics, phonetics, and computational
speech recognition and synthesis study the dynamics of producing and
comprehending language in the individual on a scale of milliseconds.
Yet there is evidence that linguistic variation at these different
time scales is linked, even in the domain of higher-level syntactic
choices. This is a primary finding in the present study of dative
constructions, illustrated by (1a,b), in Australian and American English.
1a) Who gave you that wonderful watch? (V NP NP)
b) Who gave that wonderful watch to you? (V NP PP)
We use a very accurate multilevel probabilistic model of corpus dative
productions (Bresnan, Cueni, Nikitina, and Baayen 2007) to measure the
predictive capacities of both American and Australian subjects in
three pairs of parallel psycholinguistic experiments involving
sentence ratings (Bresnan 2007), decision latencies during reading
(Ford 1983), and sentence completion. The experimental items were all
sampled together with their contexts from the database of corpus
datives, stratified by corpus model probabilities.
We find that the Australian subjects share with the American subjects
a sensitivity to corpus probabilities. But they also show covarying
differences, notably a stronger end-weight effect of the recipient in
the ratings task and the absence of a dependency-length effect of the
theme argument in the decision latency task (cf. Grodner and Gibson
2005). A unifying explanation for these differences is that decision
latencies for `to' are reduced and naturalness ratings are increased
when a PP is consistent with expectation. The Australian group would
then be predicted to have a higher expectation of PP than the US
group. This prediction is borne out by the sentence completion tasks,
which showed that the Australians produced NP PP completions more than
the American subjects in the same contexts. These findings suggest
that subtle variations in the experiences of the dative construction
by historically and spatially divergent speaker groups can create
measurable differences in internalized expectations in individuals
at the millisecond level.
