This paper presents an approach to artificial intelligence planning based on linear temporal logic (LTL). A simple and easy-to-use planning language is described, Planning Domain Description Language with control Knowledge (PDDL-K), which allows one to specify a planning problem together with heuristic information that can be of help for both pruning the search space and finding better quality plans. The semantics of the language is given in terms of a translation into a set of LTL formulae. Planning (...) is then reduced to “executing” the LTL encoding, i.e. to model search in LTL. The feasibility of the approach has been successfully tested by means of the system Pdk, an implementation of the proposed method. (shrink)

This paper is concerned with those elements of planning knowledge that are common to both understanding someone else's plan and creating a plan for one's own use. This planning knowledge can be divided into two bodies: Knowledge about the world, and knowledge about the planning process itself. Our interest here is primarily with the latter corpus. The central thesis is that much of the knowledge about the planning process itself can be formulated in terms of higher‐level goals and plans called (...) meta‐goals and meta‐plans. These entities can then be used by the same understanding and planning mechanisms that process ordinary goals and plans. However, the meta‐planning knowledge now enables these mechanisms to handle much more complicated situations in a uniform manner.Systems based on meta‐planning would have a number of advantages over existing problem solving and understanding systems. The same knowledge could be shared by both a planner and understander, and both would be able to handle complex situations elegantly. In addition, in planning, the use of meta‐planning has several advantages over more traditional methods involving constraints or critics. Meta‐planning allows the full power of a problem solver to be applied to situations that are generally amenable only to special purpose processing. In addition, meta‐planning facilitates the representation of some situations that are difficult to express otherwise. We have begun to introduce meta‐planning knowledge into two systems: PAM, a story understanding program, and PANDORA, a problem solving and plannin̈g system. (shrink)

Mirror systems must be supplemented by a planning capability to allow language to evolve. A capability for creating, storing, and executing plans for sequences of actions, having evolved in primates, was applied to sequences of communicatory acts. Language could exploit this already-existing capability. Further steps in language evolution may parallel steps seen in the development of modern children.

The human person has been analyzed from several points of view throughout the history. Great theologians, philosophers, anthropologists and sociologists and other specialists have written extensively on the subject. The philosophical contribution centered on the human person has been significant throughout history. In the last century, Romano Guardini, who received the Erasmus Prize for Best European Humanist and called "Master of Life" offers a view of reality man-centered, through a thin, deep and coherent approach on the individual. His work has (...) been labeled by some philosophers within the personalist current, and although his contributions were many, we want to highlight the elements of the meeting, the language and the self-acceptance. In this paper we propose how this approach to the human person can become an intinerary embodied in reality, that can help today to seek clarification and start delving into own personal knowledge enlightened by faith. -/- La persona humana ha sido analizada desde varios puntos de vista a lo largo de la historia.

There is much in Bridgeman's account that I find congenial and compelling, especially appealing is Bridgeman's application of his thesis to the tie between consciousness and language. Nonetheless, I want to raise some questions about whether the tie he finds between plans and consciousness actually does hold. Not all memory and attention is conscious. Although attention and accessing of memories are required to execute plans, we need not be at all conscious of the relevant states of memory and attention. (...) Nor need we be conscious of the objects that those acts of attention and accessed memories are about. We need not necessarily appeal to the executing of plans to explain the important tie between language and consciousness. (shrink)

In this article we propose that executive functions play a key role in the origin of language. Our proposal is based on the methodological assumption that some of the cognitive systems involved in language functioning are also involved in its phylogenetic origin. In this regard, we demonstrate that a key property of language functioning is discourse coherence. Such property is not dependent on grammatical elements but rather is processed by cognitive systems that are not specific for (...) class='Hi'>language, namely the executive functions systems of action planning, control and organization. Data from cognitive archaeology on the making of stone tools show that the processes requested to produce Prehistoric tools imply action organization operations similar to those involved in the processing of coherence. Based on these considerations, we propose that executive functions represent the link between stone tool making and language origins and suggest that they allowed our ancestors to develop forms of proto-discourse governed by coherence.

Speech planning is a sophisticated process. In dialog, it regularly starts in overlap with an incoming turn by a conversation partner. We show that planning spoken responses in overlap with incoming turns is associated with higher processing load than planning in silence. In a dialogic experiment, participants took turns with a confederate describing lists of objects. The confederate’s utterances (to which participants responded) were pre‐recorded and varied in whether they ended in a verb or an object noun and whether this (...) ending was predictable or not. We found that response planning in overlap with sentence‐final verbs evokes larger task‐evoked pupillary responses, while end predictability had no effect. This finding indicates that planning in overlap leads to higher processing load for next speakers in dialog and that next speakers do not proactively modulate the time course of their response planning based on their predictions of turn endings. The turn‐taking system exerts pressure on the language processing system by pushing speakers to plan in overlap despite the ensuing increase in processing load. (shrink)

The idea that natural language grammar and planned action are relatedsystems has been implicit in psychological theory for more than acentury. However, formal theories in the two domains have tendedto look very different. This article argues that both faculties sharethe formal character of applicative systems based on operationscorresponding to the same two combinatory operations, namely functional composition and type-raising. Viewing them in thisway suggests simpler and more cognitively plausible accounts of bothsystems, and suggests that the language faculty (...) evolved in the speciesand develops in children by a rather direct adaptation of a moreprimitive apparatus for planning purposive action in the world bycomposing affordances of objects or tools. Theknowledge representation that underlies such planning is alsoreflected in the natural language semantics of tense, mood, andaspect, which the paper begins by arguing provides the key tounderstanding both systems.

A new theory of problem solving is presented, which embeds problem solving in the theory of action; in this theory, a problem is just a difficult action. Making this work requires a sophisticated language for‐talking about plans and their execution. This language allows a broad range of types of action, and can also be used to express rules for choosing and scheduling plans. To ensure flexibility, the problem solver consists of an interpreter driven by a theorem prover which (...) actually manipulates formulas of the language. Many examples of the use of the system six given. including an extended treatment of the world of blocks. Limitations and extensions of the system are discussed at length. It is concluded that a rule‐based problem solver is necessary and feasible, but that much more work remains to be done on the underlying theory of planning and acting. (shrink)

This paper analyzes the skilled performance of rock climbing through the framework of Embodied and Enacted Cognitive Science. It introduces a notion of enactive planning that is part of one mindful activity of ongoing responsiveness to the affordances of the wall. The paper takes two distinct planning activities involved in rock climbing—route-reading and visualizing—and clarifies them through the enactivist and ecological concepts of nested affordances, prospecting, recalibrating, marking, and corporeal imaginings, as well as Rylean concept of heeding. The paper shows (...) that an enactive approach to planning can make sense of both the planning done in preparation of the climb, and re-planning done during the mindful performance, without invoking additional cognitive architectures.

The term “time-plan” is introduced in the article to sum up the diversity of temporal processes described by Jakob von Uexküll (1864–1944) in the frameworkof the general Planmässigkeit of nature. Although Uexküll hardly had any connections with his contemporary philosophies of time, the theme of the subjectivetimes and timing of the organisms forms an essential part of his umwelt theory. As an alternative to the dominance of evolutionary time in biological discussions, Uexküll took perceptual and developmental times of organisms as (...) his natural scientific priorities. While discussing the characteristics of the latter, Uexküll departs from an epigenetic position. Discussion about perceptual time entails detecting the primary units of time (moments) as well as how the succession of moments results in the perception of movement. The last part of the article will explicate the significance of the “time plan” concept for biophilosophical discussions. It is suggested that the bioethical question rising from Uexküll’s works may take the following form: do other biological subjects besides humans have a right to their own timing? (shrink)

English in Indonesia has foreign language status. Nevertheless, the language is greatly significant to the country due to its numerous regional and global appeals. The current language policy of Indonesia ensures that the language is taught to children from junior high school level. However, as a reflection of a language that has not been prioritised in school curriculum, school leavers largely have limited grasp of the language by the time they enrol into university programmes. (...) This study attempts to highlight institutional practices in student enrolment into and graduation from English programmes. It is also concerned with issues that are perceived to have derived from the policy. Based on interviews with 23 academics from five universities in Central Java, the majority of whom are administrators, policy-related issues of the English language are identified in this paper. Findings include communication skill difficulties faced by English majors and the juxtaposition of state and private universities in terms of student recruitment. The findings are significant in informing stakeholders such as policy makers, administrators, language instructors, and other practitioners about the impact of language policy and planning on practices in higher education institutions in Central Java and in assisting future decision-making processes whereby the consequences are far-reaching.

Recent advances in natural language processing have given rise to a new kind of AI architecture: the language agent. By repeatedly calling an LLM to perform a variety of cognitive tasks, language agents are able to function autonomously to pursue goals specified in natural language and stored in a human-readable format. Because of their architecture, language agents exhibit behavior that is predictable according to the laws of folk psychology: they function as though they have desires (...) and beliefs, and then make and update plans to pursue their desires given their beliefs. We argue that the rise of language agents significantly reduces the probability of an existential catastrophe due to loss of control over an AGI. This is because the probability of such an existential catastrophe is proportional to the difficulty of aligning AGI systems, and language agents significantly reduce that difficulty. In particular, language agents help to resolve three important issues related to aligning AIs: reward misspecification, goal misgeneralization, and uninterpretability. (shrink)

Planning with incomplete knowledge becomes a very active research area since late 1990s. Many logical formalisms introduce sensing actions and conditional plans to address the problem. The action language $\mathcal{A}_{K}$ invented by Son and Baral is a well-known framework for this purpose. In this paper, we propose so-called cautious and weakly cautious semantics for $\mathcal{A}_{K}$ , in order to allow an agent to generate and execute reliable plans in safety-critical environments. Intuitively speaking, cautious and weakly cautious semantics enable the (...) agent to know exactly what happens after the execution of an action. Computational complexity analysis shows that cautious semantics reduces the reasoning complexity of $\mathcal{A}_{K}$ , it is also worth to point out that many useful domains could still be expressed with this setting. Another important contribution of our work is the development of Hoare style proof systems. These proof systems are served as inference mechanisms for the verification of conditional plans, and proved to be sound and complete. In addition, they could also be used for plan generation, in the sense that constructing a derivation is indeed a procedure to finding a plan. We point out that the proof systems posses a nice property for off-line planning, that is, the agent could generate and store short proofs in her spare time, and perform quick plan query by easily constructing a long proof from the stored shorter ones (under the assumption that sufficient proofs are stored).

We describe how Intuitionistic Linear Logic can be used to provide a unified logical account for agents to find and execute plans. This account supports the modelling of agent interaction, including dialogue; allows agents to be robust to unexpected events and failures; and supports significant reuse of agent specifications. The framework has been implemented and several case studies have been considered. Further applications include human–computer interfaces as well as agent interaction in the semantic web.

Recent studies on mind‐wandering reveal its potential role in goal exploration and planning future actions. How to understand these explorative functions and their impact on planning remains unclear. Given certain conceptions of intentions and beliefs, the explorative functions of mind‐wandering could lead to regular reconsideration of one's intentions. However, this would be in tension with the stability of intentions central to rational planning agency. We analyze the potential issue of excessive reconsideration caused by mind‐wandering. Our response resolves this tension, presenting (...) a model that aligns the roles of mind‐wandering in planning with empirical evidence and the sustained stability of intentions. (shrink)

We introduce a computational theory of situated language understanding in which the meaning of words and utterances depends on the physical environment and the goals and plans of communication partners. According to the theory, concepts that ground linguistic meaning are neither internal nor external to language users, but instead span the objective‐subjective boundary. To model the possible interactions between subject and object, the theory relies on the notion of perceived affordances: structured units of interaction that can be used (...) for prediction at multiple levels of abstraction. Language understanding is treated as a process of filtering perceived affordances. The theory accounts for many aspects of the situated nature of human language use and provides a unified solution to a number of demands on any theory of language understanding including conceptual combination, prototypicality effects, and the generative nature of lexical items.To support the theory, we describe an implemented system that understands verbal commands situated in a virtual gaming environment. The implementation uses probabilistic hierarchical plan recognition to generate perceived affordances. The system has been evaluated on its ability to correctly interpret free‐form spontaneous verbal commands recorded from unrehearsed game play between human players. The system is able to “step into the shoes” of human players and correctly respond to a broad range of verbal commands in which linguistic meaning depends on social and physical context. We quantitatively compare the system's predictions in response to direct player commands with the actions taken by human players and show generalization to unseen data across a range of situations and verbal constructions.

This paper explores the truism that people think about what they say. It proposes that, to satisfy their own goals, people often plan their speech acts to affect their listeners' beliefs, goals, and emotional states. Such language use can be modelled by viewing speech acts as operators in a planning system, thus allowing both physical and speech acts to be integrated into plans. Methodological issues of how speech acts should be defined in a planbased theory are illustrated by defining (...) operators for requesting and informing. Plans containing those operators are presented and comparisons are drawn with Searle's formulation. The operators are shown to be inadequate since they cannot be composed to form questions (requests to inform) and multiparty requests (requests to request). By refining the operator definitions and by identifying some of the side effects of requesting, compositional adequacy is achieved.The solution leads to a metatheoretical principle for modelling speech acts as planning operators.

The idea of man in José Gaos could be explained taking in account two essential axes that make an inter-relationship between them and define man substantially: 1) antinomy love-hate-emotions and motions-expression and 2) reason-thought-language. The first is “the condition of possibility” of the second, being the element more suitable and radical that allows man to think concepts. The emotions and motions impose conditions over his will and determine the moral being that is. The man is a unity, but at (...) the same time, is an oscillation between opposites that make him take consciousness of his individuality, from the others, his historicity and intersubjectivity. The Gaos proposal is an important contribution to the anthropological reflection of the moment, because of the analysis categories that offers, of undeniable value, to the better understanding of suitable aspects of the being and acting of the Latino American man.

‘Language and End Time’ is a translation of Sections I, IV and V of ‘Sprache und Endzeit’, a substantial essay by Günther Anders that was published in eight instalments in the Austrian journal FORVM from 1989 to 1991. The original essay was planned for inclusion in the third volume of The Obsolescence of Human Beings. ‘Language and End Time’ builds on the diagnosis of ‘our blindness toward the apocalypse’ that was advanced in the first volume of The (...) Obsolescence in 1956. The essay asks if there is a language that is capable of making us fully comprehend the looming ‘man-made apocalypse’. In response to this, it offers a critique of philosophical jargon and of the putatively ‘objective’ language of science, which are both dismissed as unsuitable. Sections I, IV and V introduce this core problematic. The selection of this text for inclusion in this special journal issue responds to present-day realities that inscribe Anders’s reflections on nuclear science and the nuclear situation into new contexts. The critique that ‘Language and End Time’ advances resonates with the way in which the decisions of a few companies and individuals are shaping the future of life on earth. At the same time, the wider stakes of Anders’s turn against the language employed by scientists are newly laid bare by the realities and politics of climate change and fake news. In this new context, the language of science is all too readily dismissed as if it were a mere idiom that can be ignored without consequence. It is against the backdrop of a future that is, if anything, more uncertain than at the time of Anders’s writing, that the essay’s reflections on popularisation, the limits of language and the nature of truth gain added significance.

Language isn't the only way to cross modules, nor is it the only module with access to both input and output. Minds don't generally work across modules because this leads to combinatorial explosion in search and planning. Language is special in being a good vector for mimetics, so it becomes associated with useful cross-module concepts we acquire culturally. Further, language is indexical, so it facilitates computationally expensive operations.

I demonstrate that a "speech act" theory of meaning for imperatives is—contra a dominant position in philosophy and linguistics—theoretically desirable. A speech act-theoretic account of the meaning of an imperative !φ is characterized, broadly, by the following claims. -/- LINGUISTIC MEANING AS USE !φ’s meaning is a matter of the speech act an utterance of it conventionally functions to express—what a speaker conventionally uses it to do (its conventional discourse function, CDF). -/- IMPERATIVE USE AS PRACTICAL !φ's CDF is to (...) express a practical (non-representational) state of mind—one concerning an agent's preferences and plans, rather than her beliefs. -/- Opposed to speech act accounts is a preponderance of views which deny that a sentence's linguistic meaning is a matter of what speech act it is used to perform, or its CDF. On such accounts, meaning is, instead, a matter of "static" properties of the sentence—e.g., how it depicts the world as being (or, more neutrally, the properties of a model-theoretic object with which the semantic value of the sentence co-varies). On one version of a static account, an imperative 'shut the window!' might, for instance, depict the world as being such that the window must be shut. -/- Static accounts are traditionally motivated against speech act-theoretic accounts by appeal to supposedly irremediable explanatory deficiencies in the latter. Whatever a static account loses in saying (prima facie counterintuitively) that an imperative conventionally represents, or expresses a picture of the world, is said to be offset by its ability to explain a variety of phenomena for which speech act-theoretic accounts are said to lack good explanations (even, in many cases, the bare ability to offer something that might meet basic criteria on what a good explanation should be like). -/- I aim to turn the tables on static accounts. I do this by showing that speech act accounts are capable of giving explanations of phenomena which fans of static accounts have alleged them unable to give. Indeed, for a variety of absolutely fundamental phenomena having to do with the conventional meaning of imperatives (and other types of practical language), speech act accounts provide natural and theoretically satisfying explanations, where a representational account provides none.

It can be a great challenge for second language learners to comprehend meanings that are implied in utterances rather than the surface meaning of what was said. Moreover, L2 learners’ attitudes toward pragmatic learning are unknown. This mixed-methods study investigates L2 learners’ ability to comprehend conversational implicatures. It also explores their beliefs about and intentions to develop this ability using Ajzen’s theory of planned behavior. A total of 498 freshmen from a public university in China participated in the (...) study. Data were collected using a web-based test, stimulated recall tasks and semi-structured interviews. Results show that the participants differed in recognizing the intended meanings. Complicated factors account for the variations. In addition to the types of implicature, learners’ beliefs about developing pragmatic comprehension also influence their learning intention, and subsequent performance. These beliefs include learners’ multi-layered, complex attitudes toward the outcomes of pragmatic learning, perceived self-efficacy beliefs regarding language proficiency and L2 cultural knowledge, actual behavioral control over opportunities and resources for pragmatic learning, and perceptions of less social pressure on pragmatic learning. The use of TPB may help language teachers and test designers to understand learners’ beliefs about L2 pragmatic learning in the English as a foreign language context. Understanding the factors influencing learners’ intention will help design more effective teaching curricula that may integrate pragmatic instruction and testing in the future. (shrink)

What is the role of language in social interaction? What does language bring to social encounters? We argue that language can be conceived of as a tool for interacting minds, enabling especially effective and flexible forms of social coordination, perspective-taking and joint action. In a review of evidence from a broad range of disciplines, we pursue elaborations of the language-as-a-tool metaphor, exploring four ways in which language is employed in facilitation of social interaction. We argue (...) that language dramatically extends the possibility-space for interaction, facilitates the profiling and navigation of joint attentional scenes, enables the sharing of situation models and action plans, and mediates the cultural shaping of interacting minds.

How is it that many schizophrenics identify certain instances of verbal imagery as hallucinatory? Most investigators have assumed that alterations in sensory features of imagery explain this. This approach, however, has not yielded a definitive picture of the nature of verbal hallucinations. An alternative perspective suggests itself if one allows the possibility that the nonself quality of hallucinations is inferred on the basis of the experience of unintendedness that accompanies imagery production. Information-processing models of “intentional” cognitive processes call for abstract (...) planning representations that are linked to goals and beliefs. Unintended actions - and imagery - can reflect planning disruptions whereby cognitive products do not cohere with concurrent goals. A model of schizophrenic speech disorganization is presented that postulates a disturbance of discourse planning. Insofar as verbal imagery can be viewed as inwardly directed speech, a consequence of such planning disturbances could be the production of unintended imagery. This link between the outward disorganization of schizophrenic speech and unintended verbal imagery is statistically supported by comparing the speech behavior of hallucinating and nonhallucinating schizophrenics. Studies of “borderline” hallucinations during normal, “goal-less” relaxation and drowsiness suggest that experiential unintendedness leads to a nonpathological variant of hallucinatory otherness that is correctable upon emerging from such passive cognitive states. This contrasts with the schizophrenic case, where nonconcordance with cognitive goals reinforces the unintendedness of verbal images and sustains the conviction of an external source. This model compares favorably with earlier models of verbal hallucinations and provides further evidence for a language production disorder in many schizophrenics.Short Abstract: How is it that many schizophrenics identify certain instances of verbal imagery as hallucinatory? This paper proposes that the critical feature identifying hallucinations is the experience of unintendedness. This experience is nonpathological during passive conscious states but pathological if occurring during goal-directed cognitive processing. A model of schizophrenic speech disorganization is presented that postulates a disturbance of discourse planning that specifies communicative intentions. These alterations could generate unintended verbal imagery as well. Statistical data are offered to support the model, and relevant empirical studies are reviewed. (shrink)

Language policies are increasingly acknowledged as being a necessary component of many decisions taken in the areas of the labor market, education, minority languages, mobility, and social inclusion of migrants. They can affect the democratic control of political organizations, and they can either entrench or reduce inequalities. These are the central topics of this book. Economists, philosophers, political scientists, and sociolinguists discuss – from an interdisciplinary perspective – the distributive socio-economic effects of language policies, their impact on justice (...) and inequality at the national or international level, as well as the connection between language choices and an inclusive access to public services. The range of social and economic issues raised by linguistic diversity in contemporary societies is large, and this requires new approaches to tackle them. This book provides new input to design better, more efficient, and fair language policies in order to manage linguistic diversity in different areas. Topics covered include: theoretical models of linguistic justice and linguistic disadvantage; the assessment of the socio-economic consequences of language policies; the evaluation of the costs, benefits, and degree of inclusion of language planning measures; the politics of migrants’ linguistic integration; as well as multilingualism and economic activities. These topics are discussed in different contexts, including the areas inhabited by linguistic minorities, cities receiving migrants, and supranational organizations. (shrink)

An examination of the ways human movement can be represented as a formal language and how this language can be mediated technologically. In Motion and Representation, Nicolás Salazar Sutil considers the representation of human motion through languages of movement and technological mediation. He argues that technology transforms the representation of movement and that representation in turn transforms the way we move and what we understand to be movement. Humans communicate through movement, physically and mentally. To record and capture (...) integrated movement (both bodily and mental), by means of formal language and technological media, produces a material record and cultural expression of our evolving kinetic minds and identities. Salazar Sutil considers three forms of movement inscription: a written record (notation), a visual record (animation), and a computational record (motion capture). He focuses on what he calls kinetic formalism—formalized movement in such pursuits as dance, sports, live animation, and kinetic art, as well as abstract definitions of movement in mathematics and computer science. He explores the representation of kinetic space and spatiotemporality; the representation of mental plans of movement; movement notation, including stave notation (Labanotation) and such contemporary forms of notation as Choreographic Language Agent; and the impact of digital technology on contemporary representations of movement—in particular motion capture technology and Internet transfer protocols. Motion and Representation offers a unique cultural theory of movement and of the ever-changing ways of representing movement. (shrink)

Among philosophers, there are at least two prevalent views about the core concept of intentional action. View I (Adams 1986, 1997; McCann 1986) holds that an agent S intentionally does an action A only if S intends to do A. View II (Bratman 1987; Harman 1976; and Mele 1992) holds that there are cases where S intentionally does A without intending to do A, as long as doing A is foreseen and S is willing to accept A as a consequence (...) of S’s action. Joshua Knobe (2003a) presents intriguing data that may be taken to support the second view.1 Knobe’s data show an asymmetry in folk judgements. People are more inclined to judge that S did A intentionally, even when not intended, if A was perceived as causing a harm (e.g. harming the environment). There is an asymmetry because people are not inclined to see S’s action as intentional, when not intended, if A is perceived as causing a benefit (e.g. helping the environment). In this paper we will discuss Knobe’s results in detail. We will raise the question of whether his ordinary language surveys of folk judgments have accessed core concepts of intentional action. We suspect that instead Knobe’s surveys are tapping into pragmatic aspects of intentional language and its role in moral praise and blame. We will suggest alternative surveys that we plan to conduct to get at this difference, and we will attempt to explain the pragmatic usage of intentional language. (shrink)

Imagine a telephone conversation between a presidential aide and a wealthy supporter, shortly after news breaks that the president plans to veto a bill that the supporter strongly favors. The nervous aide opens with “I'm calling to let you know that the president regrets his, uh, his decision…” The supporter's hopes rise at the intimation that the president changed his mind. But when the aide continues: “… did not meet with your apparel, I mean, your approval,” the crestfallen (and, perhaps, (...) former) supporter realizes that the president is sorry merely about the impact of his decision, not the decision itself. The aide's utterance seems to mean one thing at first, but something entirely different in the end. Unintentional verbal about‐faces of this kind are common in everyday language use – the outspoken owner of an American baseball team recently said that she regretted her remarks offended many people – yet listeners rarely notice the miscues, the wealthy supporter notwithstanding. This is one of the chief motivations behind the psycholinguistic study of language use. (shrink)
