Deictic expressions, like English ‘this, that, here, and there’ occur in all known human languages. They are typically used to individuate objects in the immediate context in which they are uttered, by pointing at them so as to direct attention to them. The object, or demonstratum is singled out as a focus, and a successful act of deictic reference is one that results in the Speaker (Spr) and Addressee (Adr) attending to the same referential object. Thus,
(1)A:Oh, there’sthat guy again (pointing)B:Oh yeah, now I see him (fixing gaze on the guy)
(2)A:I’ll have that one over there (pointing to a dessert on a tray)B:This? (touching pastry with tongs)A:yeah, that looks greatB:Here ya’ go (handing pastry to customer)
In an exchange like (1), A’s utterance spotlights the individual guy, directing B’s attention to him, and B’s response (both verbal and ocular) displays that he has recognized him. In (2) A’s utterance individuates one pastry among several, B’s response makes sure he’s attending to the right one, A reconfirms and B completes by presenting the pastry to him. If we compare the two examples, it is clear that the underscored deictics can pick out or present individuals without describing them. In a similar way, “I, you, he/she, we, now, (back) then,” and their analogues are all used to pick out individuals (persons, objects, or time frames), apparently without describing them. As a corollary of this semantic paucity, individual deictics vary extremely widely in the kinds of object they may properly denote: ‘here’ can denote anything from the tip of your nose to planet Earth, and ‘this’ can denote anything from a pastry to an upcoming day (this Tuesday). Under the same circumstance, ‘this’ and ‘that’ can refer appropriately to the same object, depending upon who is speaking, as in (2). How can forms that are so abstract and variable over contexts be so specific and rigid in a given context? On what parameters do deictics and deictic systems in human languages vary, and how do they relate to grammar and semantics more generally?

The concept of innateness (innate is first recorded in the period 1375–1425; from Latin innātus “inborn”) relates to types of behavior and knowledge that are present in the organism since birth (in fact, since fertilization), prior to any sensory experience with the environment. The term has been applied to two general types of qualities. The first consists of instinctive and inflexible reflexes and behaviors, which are apparent in survival, mating, and rearing activities. The other relates to cognition, with certain concepts, ideas, propositions, and particular ways of mental computation suggested to be part of one’s biological makeup. While both types of innatism have a long history in human philosophy and science (e.g., Plato and Descartes), some bias appears to exist in favor of claims for inherent behavioral traits, which are typically accepted when satisfactory empirical evidence is provided. One famous example is Lorenz’s demonstration of imprinting, a natural phenomenon that obeys a predetermined mechanism and schedule (Lorenz’s incubator-hatched goslings imprinted on his boots, the first moving object they encountered). Likewise, there seems to be little controversy in regard to predetermined ways of organizing sensory information, as is the case with the detection and classification of shapes and colors by the mind. In contrast, the idea that certain types of abstract knowledge may be part of an organism’s biological endowment (i.e., not learned) is typically faced with a greater sense of skepticism, and touches on a fundamental question in epistemological philosophy: Can reason be based (to a certain extent) on a priori knowledge—that is, knowledge that precedes and is independent of experience? The most influential and controversial claim for such innate knowledge in modern science is Chomsky’s breakthrough nativist theory of Universal Grammar in language and the famous “Argument from the Poverty of the Stimulus.” The main Chomskyan hypothesis is that all human beings share a preprogrammed linguistic infrastructure consisting of a finite collection of rules that, in principle, may generate (through combination or transformation) an infinite number of (only) grammatical sentences. Thus, the innate grammatical system constrains and structures the acquisition and use of all natural languages.
Computational models of human sentence comprehension help researchers reason about how grammar might actually be used in the understanding process. Taking a cognitivist approach, this article relates computational psycholinguistics to neighboring fields (such as linguistics), surveys important precedents, and catalogs open problems.
Throughout the 20th century, structuralist and generative linguists have argued that the study of the language system (langue, competence) must be separated from the study of language use (parole, performance), but this view of language has been called into question by usage-based linguists who have argued that the structure and organization of a speaker’s linguistic knowledge is the product of language use or performance. On this account, language is seen as a dynamic system of fluid categories and flexible constraints that are constantly restructured and reorganized under the pressure of domain-general cognitive processes that are not only involved in the use of language but also in other cognitive phenomena such as vision and (joint) attention. The general goal of usage-based linguistics is to develop a framework for the analysis of the emergence of linguistic structure and meaning.
In order to understand the dynamics of the language system, usage-based linguists study how languages evolve, both in history and language acquisition. One aspect that plays an important role in this approach is frequency of occurrence. As frequency strengthens the representation of linguistic elements in memory, it facilitates the activation and processing of words, categories, and constructions, which in turn can have long-lasting effects on the development and organization of the linguistic system. A second aspect that has been very prominent in the usage-based study of grammar concerns the relationship between lexical and structural knowledge. Since abstract representations of linguistic structure are derived from language users’ experience with concrete linguistic tokens, grammatical patterns are generally associated with particular lexical expressions.
