Language and life history: a new perspective on the development and evolution of human language

It has long been claimed that Homo sapiens is the only species that has language, but only recently has it been recognized that humans also have an unusual pattern of growth and development. Social mammals have two stages of pre-adult development: infancy and juvenility. Humans have two additional prolonged and pronounced life history stages: childhood, an interval of four years extending between infancy and the juvenile period that follows, and adolescence, a stage of about eight years that stretches from juvenility to adulthood. We begin by reviewing the primary biological and linguistic changes occurring in each of the four pre-adult ontogenetic stages in human life history. Then we attempt to trace the evolution of childhood and juvenility in our hominin ancestors. We propose that several different forms of selection applied in infancy and childhood; and that, in adolescence, elaborated vocal behaviors played a role in courtship and intrasexual competition, enhancing fitness and ultimately integrating performative and pragmatic skills with linguistic knowledge in a broad faculty of language. A theoretical consequence of our proposal is that fossil evidence of the uniquely human stages may be used, with other findings, to date the emergence of language. If important aspects of language cannot appear until sexual maturity, as we propose, then a second consequence is that the development of language requires the whole of modern human ontogeny. Our life history model thus offers new ways of investigating, and thinking about, the evolution, development, and ultimately the nature of human language.     

Coreferential Relations in Basque: The Annotation Process

In this paper we present the coreferential tagging of part of the EPEC Corpus of Basque. Although coreference is a pragmatic linguistic phenomenon highly dependent on the situational context, it shows some language-specific patterns that vary according to the features of each language. Due to the fact that Basque is not an Indo-European language, it differs considerably in grammar from the languages spoken in surrounding areas. We will explain these features and the decisions made in each case. After describing the criteria defined for coreferential tagging in Basque, the annotation process will be explained. Our annotation is based on a morphologically and syntactically annotated corpus that provides us with a manageable environment, in which the specific structures that are part of a reference chain can be more easily identified. A part of the corpus was tagged by two annotators who marked up the same text independently, and by another annotator that acted as judge, solving problems in case of disagreement. All this process has been automatized as a result of previous studies carried out in this field. The automatic detection of mentions (Soraluze et al., in: Proceedings of Konvens, 2012) has provided us with a better working environment, and given us the possibility to build a first significant corpus for a later computational treatment of automatic coreferential resolution.     

Knowledge,conservatism, and pragmatics

The apparent contextual variability exhibited by ‘knows’ and its cognates—brought to attention in examples like Keith DeRose’s Bank Case—poses familiar problems for conservative forms of invariantism about ‘knows’. The paper examines and criticises a popular response to those problems, one that involves appeal to so-called ‘pragmatic’ features of language. It is first argued, contrary to what seems to have been generally assumed, that any pragmatic defence faces serious problems with regard to our judgments about retraction. Second, the familiar objection that the pragmatic effects at issue do not seem to be cancellable is considered. Advocates of the pragmatic defence have suggested that cancellability concerns can be dealt with fairly readily. It is shown both that their recent attempts to respond to those concerns, and some other possible attempts, are unsuccessful. Finally, it is argued that the popular relevance-based accounts, found in the work of Jessica Brown, Alan Hazlett, and Patrick Rysiew, fail to provide a satisfactory explanation of our judgments.

The effect of lexical, pragmatic, and morphological violations on reading time and deviance ratings of English and German sentences

Effects on reading time and deviance ratings of word-choice violations were studied at the surface code, propositional textbase, and situation model levels of representation in German and English sentences. Lexical violations (propositional textbase level) such as The housewife massaged the bread dough were rated as more deviant from normal language than were pragmatic violations (situation model level) such as The police officer shot the parking violator, although the pragmatic violations took longer to comprehend. The addition of a morphological (surface code) violation through the wrong form of an article (e.g., a ugly car) decreased reading time but only in cases where that material was deeply processed and where the morphology carried substantial syntactic information (e.g., in German, the definite article carries case, gender, and number information). The results thus confirmed the operation of comprehension strategies at multiple levels of representation and identified some cross-linguistic generality in comprehension and some language differences.     

Online interpretation of scalar quantifiers: insight into the semantics-pragmatics interface

Scalar implicature has served as a test case for exploring the relations between semantic and pragmatic processes during language comprehension. Most studies have used reaction time methods and the results have been variable. In these studies, we use the visual-world paradigm to investigate implicature. We recorded participants’ eye movements during commands like “Point to the girl that has some of the socks” in the presence of a display in which one girl had two of four socks and another had three of three soccer balls. These utterances contained an initial period of ambiguity in which the semantics of some was compatible with both characters. This ambiguity could be immediately resolved by a pragmatic implicature which would restrict some to a proper subset. Instead in Experiments 1 and 2, we found that participants were substantially delayed, suggesting a lag between semantic and pragmatic processing. In Experiment 3, we examined interpretations of some when competitors were inconsistent with the semantics (girl with socks vs. girl with no socks). We found quick resolution of the target, suggesting that previous delays were specifically linked to pragmatic analysis.     

Impaired Interpretation of Others’ Behavior is Associated with Difficulties in Recognizing Pragmatic Language in Patients with Schizophrenia

Much attention has been paid to the pragmatic language function in schizophrenia. This study of Japanese patients with schizophrenia examined the relationship between impaired interpretation of the behaviors of other people in social contexts and the ability to recognize metaphor and irony. We assessed 34 patients with schizophrenia and 34 normal subjects using first- and second-order theory of mind tasks, the Metaphor and Sarcasm Scenario Test, and the Dewey Story Test (which tests the ability to judge others’ social behaviors). We compared the performance between the groups and analyzed correlations between the tasks. All tasks revealed significant deficits in the patients compared with the controls. In the patient group, metaphor comprehension was correlated with the ability to judge normal behaviors, and irony comprehension was correlated with the ability to judge abnormal behaviors, suggesting that deficits of social cognition in schizophrenia include these two types of factors associated with pragmatic language.     

The kindergarten-path effect: studying on-line sentence processing in young children

A great deal of psycholinguistic research has focused on the question of how adults interpret language in real time. This work has revealed a complex and interactive language processing system capable of rapidly coordinating linguistic properties of the message with information from the context or situation (e.g. Altmann & Steedman, 1988; Britt, 1994; Tanenhaus, Spivey-Knowlton, Eberhard & Sedivy, 1995; Trueswell & Tanenhaus, 1991). In the study of language acquisition, however, surprisingly little is known about how children process language in real time and whether they coordinate multiple sources of information during interpretation. The lack of child research is due in part to the fact that most existing techniques for studying language processing have relied upon the skill of reading, an ability that young children do not have or are only beginning to acquire. We present here results from a new method for studying children's moment-by-moment language processing abilities, in which a head-mounted eye-tracking system was used to monitor eye movements as participants responded to spoken instructions. The results revealed systematic differences in how children and adults process spoken language: Five Year Olds did not take into account relevant discourse/pragmatic principles when resolving temporary syntactic ambiguities, and showed little or no ability to revise initial parsing commitments. Adults showed sensitivity to these discourse constraints at the earliest possible stages of processing, and were capable of revising incorrect parsing commitments. Implications for current models of sentence processing are discussed.     

Belief,Credence, and Pragmatic Encroachment1

This paper compares two alternative explanations of pragmatic encroachment on knowledge (i.e., the claim that whether an agent knows that p can depend on pragmatic factors). After reviewing the evidence for such pragmatic encroachment, we ask how it is best explained, assuming it obtains. Several authors have recently argued that the best explanation is provided by a particular account of belief, which we call pragmatic credal reductivism. On this view, what it is for an agent to believe a proposition is for her credence in this proposition to be above a certain threshold, a threshold that varies depending on pragmatic factors. We show that while this account of belief can provide an elegant explanation of pragmatic encroachment on knowledge, it is not alone in doing so, for an alternative account of belief, which we call the reasoning disposition account, can do so as well. And the latter account, we argue, is far more plausible than pragmatic credal reductivism, since it accords far better with a number of claims about belief that are very hard to deny.     

Religious language and the task of theology in a scientific and eco-sensitive age

In this paper I shall evaluate a trend in theology; an attempt to naturalize and reinterpret the task of theology and the nature and function of religious language. I propose that religious naturalists adopt a pragmatic view of religious language, and I also introduce the notion of Ecologically Mindful Attitude (EMA). I reach the conclusion that this pragmatic understanding of religion is not successful and that it can be challenged on several levels.     

Theoretical influences on research on language development and intervention in individuals with mental retardation

In this article, we consider the theoretical debates and frameworks that have shaped research on language development and intervention in persons with mental retardation over the past four decades. Our starting point is the nativist theory, which has been espoused most forcefully by Chomsky. We also consider more recent alternatives to the nativist approach, including the social-interactionist and emergentist approaches, which have been developed largely within the field of child language research. We also consider the implications for language development and intervention of the genetic syndrome-based approach to behavioral research advocated by Dykens and others. We briefly review the impact and status of the debates spurred by the nativist approach in research on the course of language development in individuals with mental retardation. In addition, we characterize some of the achievements in language intervention that have been made possible by the debates spurred by nativism and the various alternatives to it. The evidence we consider provides support for all three alternatives to the nativist approach. Moreover, successful interventions appear to embody elements of several of these approaches as well as other theoretical approaches (e.g., behaviorism). We conclude that language intervention must be theoretically eclectic in its approach, with different strategies appropriate for teaching different features of language, at different points in development, and for children displaying different characteristics or learning histories.     

Kant's Pragmatism

This article offers a definition of the term ‘pragmatic’, as it is used in Kant's Critique of Pure Reason. The definition offered does not make any reference to the affinities between Kant's pragmatism and the philosophies of the American or other pragmatists but draws its definiens entirely from the Kantian conceptual framework. It states that the term ‘pragmatic’ denotes imperatives, laws and beliefs of a specific type: an imperative is pragmatic if and only if it is concerned with the choice of means to individual or universal happiness; a law is pragmatic if and only if our willingness to presuppose it results from our obedience to a pragmatic imperative; and a belief is pragmatic if and only if it relates to the objective validity of pragmatic laws. This article also discusses two rival definitions of the term ‘pragmatic’ (as used by Kant) that have been brought forward by Sidney Axinn and Nicholas Rescher.     

Informal pragmatics and linguistic creativity

Examples of successful linguistic communication give rise to two important insights: (1) it should be understood most fundamentally in terms of the pragmatic success of each individual utterance, and (2) linguistic conventions need to be understood as on a par with the non-linguistic regularities that competent language users rely upon to refer. Syntax and semantics are part of what Barwise and Perry call the context of the utterance, contributing to the pragmatics of the utterance. This full and distributed multichannel context determines meaning if anything does. On the standard account of context, context disambiguates the meaning of language, but it is at least as apt in many situations to say that language disambiguates context. In practice, the two work together, sometimes with more emphasis on one than the other. Reference should be understood in pragmatic terms (it is an act) and, since success is often achieved in non-standard, creative ways, any formalisation of pragmatics can only be partial. The need for such an inventive approach to referring traces back to the need for language to be highly efficient, with expressions underdetermining their interpretation. Next, the shared semantic and syntactic regularities, which might seem to be independent of the context of an utterance, should be understood as also being part of that context. Past usage underdetermines how terms can be used since it allows for multiple projections. Successful reference with novel uses that are disambiguated by context can become the ground for new conventions.     

Children's understanding of ambiguous idioms and conversational perspective-taking

The aim of this study was to test the hypothesis that conversational perspective-taking is a determinant of unfamiliar ambiguous idiom comprehension. We investigated two types of ambiguous idiom, decomposable and nondecomposable expressions, which differ in the degree to which the literal meanings of the individual words contribute to the overall idiomatic meaning. We designed an experiment to assess the relationship between the acquisition of figurative comprehension and conversational perspective-taking. Our sample of children aged 5-7 years performed three conversational perspective-taking tasks (language acts, shared/unshared information, and conversational maxims). They then listened to decomposable and nondecomposable idiomatic expressions presented in context before performing a multiple-choice task (figurative, literal, and contextual responses). Results indicated that decomposable idiom comprehension was predicted by conversational perspective-taking scores and language skills, whereas nondecomposable idiom comprehension was predicted solely by language skills. We discuss our findings with respect to verbal and pragmatic skills.     

Neuropragmatics: Extralinguistic pragmatic ability is better preserved in left-hemisphere-damaged patients than in right-hemisphere-damaged patients

The aim of the present study is to compare the pragmatic ability of right- and left-hemisphere-damaged patients excluding the possible interference of linguistic deficits. To this aim, we study extralinguistic communication, that is communication performed only through gestures. The Cognitive Pragmatics Theory provides the theoretical framework: it predicts a gradient of difficulty in the comprehension of different pragmatic phenomena, that should be valid independently of the use of language or gestures as communicative means. An experiment involving 10 healthy individuals, 10 right- and 9 left-hemisphere-damaged patients, shows that pragmatic performance is better preserved in left-hemisphere-damaged (LHD) patients than in right-hemisphere-damaged (RHD) patients.     

Gricean Expectations in Online Sentence Comprehension: An ERP Study on the Processing of Scalar Inferences

There is substantial support for the general idea that a formalization of comprehenders' expectations about the likely next word in a sentence helps explaining data related to online sentence processing. While much research has focused on syntactic, semantic, and discourse expectations, the present event‐related potentials (ERPs) study investigates neurolinguistic correlates of pragmatic expectations, which arise when comprehenders expect a sentence to conform to Gricean Maxims of Conversation. For predicting brain responses associated with pragmatic processing, we introduce a formal model of such Gricean pragmatic expectations, using an idealized incremental interpreter. We examine whether pragmatic expectancies derived from this model modulate the amplitude of the N400, a component that has been associated with predictive processing. As part of its parameterization, the model distinguishes genuine pragmatic interpreters, who expect maximally informative true utterances, from literal interpreters, who only expect truthfulness. We explore the model's non‐trivial predictions for an experimental setup which uses picture‐sentence verification with ERPs recorded at several critical positions in sentences containing the scalar implicature trigger some. We find that Gricean expectations indeed affect the N400, largely in line with the predictions of our model, but also discuss discrepancies between model predictions and observations critically.
