The visual-gestural modality affords its users simultaneous movement of several independent articulators and thus lends itself to simultaneous encoding of information. Much research has focused on the fact that sign languages coordinate two manual articulators in addition to a range of non-manual articulators to present different types of linguisti...

Speech motor processes and phonological forms influence one another because speech and language are acquired and used together. This hypothesis underpins the Computational Core (CC) model, which provides a framework for understanding the limitations of perceptually-driven changes to production. The model assumes a lexicon of motor and perceptual wo...

... Unlike vocal-auditory channels, signed language does allow for a certain degree of simultaneous expression (see e.g.Loos et al. (2022) for a recent overview), but not in ways that matter to the point at hand.14 See e.g.Baker (2002Baker ( , 2010 for an argument that it is a linguistic universal that verbs and their objects combine prior to the incorporation of a subject, entailing that there is some underlying shared structure in languages with superficially different word orders. While Baker proposes a syntactic difference, in terms of movement after initial structure-generation, to account for cross-linguistic differences in word-ordering, rather than a post-syntactic difference in terms of externalization, the general point is consistent with the argument I am making. ...
This Element tries to discern the known unknowns in the field of Pragmatics, the 'Dark Matter' of the title. The authors can identify a key bottleneck in human communication, the sheer limitation on the speed of speech encoding: Pragmatics occupies the niche nestled between slow speech encoding and fast comprehension. Pragmatic strategies are tricks for evading this tight encoding bottleneck by meaning more than you say. Five such tricks are reviewed, which are all domains where the authors have made considerable progress. The authors can then ask for each of these areas, where have the authors neglected to push the frontier forward? These are the known unknowns of pragmatics, key areas, and topics for future research. The Element thus offers a brief review of some central areas of pragmatics, and a survey of targets for future research. This title is also available as Open Access on Cambridge Core.
One structural dimension that varies across languages is the simultaneous or sequential expression of meaning. Complex predicates can layer meanings together simultaneously in a single-verb predicate (SVP) or distribute them sequentially in a multiple-verb predicate (MVP). We ask whether typological variability in this dimension might be a consequence of systematic patterns of diachronic change. We examine the distribution of markers of agency and number within the verb phrase (the predicate) in the earliest stages of a young, emerging sign language in Nicaragua, Lengua de Señas Nicaragüense (LSN), beginning with homesign systems like those from which LSN originated, and progressing through two decades of transmission to new learners. We find that: (i) LSN2 signers are more likely to produce MVPs than homesigners or LSN1 signers; (ii) in the MVPs they do produce, homesigners and LSN1 signers are more likely to produce predicates that mark both agency and number simultaneously on at least one of the verbs; LSN2 signers are just as likely to produce sequences with verbs that mark agency and number in sequentially separate verbs. We discuss how language acquisition, modality, and structure, as well as specific social factors associated with each of the groups, play a role in driving these changes, and how, over time, these patterns of change might yield the diversity of forms observed across spoken and signed languages today.
This study traces the development of discrete, combinatorial structure in Zinacantec Family Homesign (‘Z Sign’), a sign language developed since the 1970s by several deaf siblings in Mexico ( Haviland 2020b ), focusing on the expression of motion. The results reveal that the first signer, who generated a homesign system without access to language models, represents motion events holistically. Later-born signers, who acquired this homesign system from infancy, distribute the components of motion events over sequences of discrete signs. Furthermore, later-born signers exhibit greater regularity of form-meaning mappings and increased articulatory efficiency. Importantly, these changes occur abruptly between the first- and second-born signers, rather than incrementally across signers. This study extends previous findings for Nicaraguan Sign Language ( Senghas et al. 2004 ) to a social group of a much smaller scale, suggesting that the parallel processes of cultural transmission and language acquisition drive language emergence, regardless of community size.
