While both pragmatic theory and experimental investigations of language using psycholinguistic methods have been well-established subfields in the language sciences for a long time, the field of Experimental Pragmatics, where such methods are applied to pragmatic phenomena, has only fully taken shape since the early 2000s. By now, however, it has become a major and lively area of ongoing research, with dedicated conferences, workshops, and collaborative grant projects, bringing together researchers with linguistic, psychological, and computational approaches across disciplines. Its scope includes virtually all meaning-related phenomena in natural language comprehension and production, with a particular focus on what inferences utterances give rise to that go beyond what is literally expressed by the linguistic material.
One general area that has been explored in great depth consists of investigations of various ‘ingredients’ of meaning. A major aim has been to develop experimental methodologies to help classify various aspects of meaning, such as implicatures and presuppositions as compared to basic truth-conditional meaning, and to capture their properties more thoroughly using more extensive empirical data. The study of scalar implicatures (e.g., the inference that some but not all students left based on the sentence Some students left) has served as a catalyst of sorts in this area, and they constitute one of the most well-studied phenomena in Experimental Pragmatics to date. But much recent work has expanded the general approach to other aspects of meaning, including presuppositions and conventional implicatures, but also other aspects of nonliteral meaning, such as irony, metonymy, and metaphors.
The study of reference constitutes another core area of research in Experimental Pragmatics, and has a more extensive history of precursors in psycholinguistics proper. Reference resolution commonly requires drawing inferences beyond what is conventionally conveyed by the linguistic material at issue as well; the key concern is how comprehenders grasp the referential intentions of a speaker based on the referential expressions used in a given context, as well as how the speaker chooses an appropriate expression in the first place. Pronouns, demonstratives, and definite descriptions are crucial expressions of interest, with special attention to their relation to both intra- and extralinguistic context. Furthermore, one key line of research is concerned with speakers’ and listeners’ capacity to keep track of both their own private perspective and the shared perspective of the interlocutors in actual interaction.
Given the rapid ongoing growth in the field, there is a large number of additional topical areas that cannot all be mentioned here, but the final section of the article briefly mentions further current and future areas of research.
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.
