Inverse number in dagaare

This chapter examines the inverse number system in Dagaare (Gur; Niger–Congo). Inverse number systems possess a number morpheme which for some nouns encodes the plural interpretation while for others it encodes the singular interpretation. This chapter argues that a principled lexical semantic classification underlies the inverse number strategy in Dagaare, guiding whether for a particular noun the inverse morpheme codes the singular or the plural interpretation. The chapter further explores the functional grounding of inverse number, in terms of frequency and individuation, and presents a formal semantic account of the inverse number system.

Looking further! The importance of embedding visual search in action

A unified account of visual search in complex everyday environments requires additional deliberations on the functional grounding of Hulleman & Olivers' (H&O's) functional viewing field (FVF) model. Their model can accommodate exploitation of information that is distributed across the immediate environment. Yet the differences in search between genuinely interacting in the environment and merely watching it should challenge researchers to look further.

Konstruktionen im Spracherwerb

The concept of ‘constructions’ covers the range from fully unanalyzed or “frozen” units to abstract and productive schemas that can be used to form new utterances, even with verbs that usually have a different valency (coercion). The dynamic nature of the construction as well as its functional grounding makes the construction particularly suitable for describing and explaining the course of language acquisition. Distributional analyses of the linguistic structures used across development as well as experimental tests on the productivity of these structures are the methodological means to assess the degree of freedom of constructions used at each point in development. In the earliest stages of development children rely heavily on bottom up processes and generalize only slowly. But with growing productivity they are able to generate new utterances top down.

On the evolution of consonant harmony: the case of secondary articulation agreement

Consonant harmony involves long-distance featural assimilation, or agreement, of consonants across intervening segments. Current correspondence-based analyses of such sound patterns assume that they originate in the cognitive exigencies of articulatory planning, either synchronically, through the functional grounding of the constraints responsible, or diachronically, whereby processing factors incrementally shape the lexicon over time. This paper challenges the validity of this assumption as an all-purpose functional explanation for the full range of long-distance consonant agreement patterns by demonstrating that a variety of diachronic trajectories underlies their emergence and evolution. Focusing on the comparatively rare phenomenon ofsecondary articulation agreement, the evolutionary histories of three cases are examined: (labio)velarisation agreement in Pohnpeian (Oceanic), palatalisation agreement in Karaim (Turkic) and pharyngealisation agreement in Tsilhqot'in (Athabaskan). These histories provide explanations for a range of synchronic properties of the systems in question, some of which are problematic for restrictive typologies of consonant harmony.
