Today’s talkUniting two strands of research in sociolinguistics:
1. Usage-based models
2. Intra-speaker longitudinal change

I Raumolin-Brunberg (2005): individual speakers of Early ModernEnglish follow community shift from 3rd singular -th to -s

I The participation of individual speakers in ongoing communitychanges in progress
Connecting lifespan change to usage-based models of grammarI Individual hears high-frequency words from these community members
more often than other words

A testing groundLifespan change (Sanko�, 2005)
I The participation of individual speakers in ongoing communitychanges in progress
Connecting lifespan change to usage-based models of grammarI Individual’s mental representations of high-frequency words pick up
the change before words he hears less often

The question that prompted this study
Does individual participation in community-level change show frequencye�ects as predicted under a theory in which input gradually shapes
production?

The community changeThe decline of [R]
I In traditional RP, [R] found intervocalically after a stressed vowel(Wells, 1982; Cruttenden, 2014)
I word-internally, e.g. squirrels
I in hiatus (‘linking’) position, e.g. all our equipment
I ‘Among the changes almost complete in British English [is that] /r/ isrealized as a post-alveolar approximant in all positions’
(Cruttenden, 2014, 83)
Research questions:
I Does Attenborough participate in this community change over time?I If so, is his change frequency-driven?

Who serves as the model in longitudinal change?
‘In their middle years, do people look to the models from older speakersthat they neglected when they were young? To what extent does inputfrom older speakers provide conservative forms to language learners?’
(Wagner and Sanko�, 2011, 305)
Laurel MacKenzie (U of Manchester) NWAV 43 20 / 24
How much of a role does community input play?I ‘. . . virtually all of the evidence for ongoing linguistic change in
adulthood derives from an increase in frequency of forms’(Tagliamonte and D’Arcy, 2009, 62–63)
I In other words, longitudinal change tends to take the shape ofindividuals manipulating their rate of use of variants they alreadycommand, rather than learning (or unlearning) a variant entirely.
I e.g. Nahkola and Saanilahti (2004); Raumolin-Brunberg (2005);Sanko� and Blondeau (2007)
I A theory in which community usage shapes individual languageproduction needs to account for the fact that individuals don’t(can’t?) simply pick up whatever they hear
Laurel MacKenzie (U of Manchester) NWAV 43 21 / 24
In sum. . .I Usage-based models raise important questions about individual
language production vis-à-vis community usageI Such theories need to make provisions for the fact that individuals can
change away from their received input. . .I (though it’s worth acknowledging that we don’t always have a firm
grasp on what that input necessarily is)I . . . and that there appear to be limits on the extent to which
individuals can be influenced by community inputI Though the community has (with good reason) been the prime focus
of many sociolinguistic studies, a focus on the individual can elucidatequestions about our capacity to learn and our capacity to change, andthe nature of human language more generally
