Here I explore the prospects for fictionalism about the mental, modeled after fictionalism about possible worlds. Mental fictionalism holds that the mental states posited by folk psychology do not exist, yet that some sentences of folk psychological discourse are true. This is accomplished by construing truths of folk psychology as “truths according to the mentalistic fiction.” After formulating the view, I identify five ways that the view appears self-refuting. Moreover, I argue that this cannot be fixed by semantic ascent (...) or by a kind of primitivism. Even so, I also show that the “self-refutation” charges are subtly question-begging. Nevertheless, the reply reveals that a mental fictionalist ought to be a kind of quietist. (shrink)

Articles on sentence in Sanskrit grammar according to Mimamsa philosophy.

Functionalism has become one of the predominant theories in the philosophy of mind, with its many merits supposedly including its capacity for precise formulation. The most common method to express this precise formulation is by means of the modified Ramsey sentence. In this article, I will apply work from the field of the philosophy of science to functionalism for the first time, examining how Newman’s objection undermines the Ramsey sentence as a means of formalising functionalism. I will also present a (...) formal variation on Newman’s objection through mathematical induction. Together, these proofs suggest that functionalism formalised by the Ramsey sentence trivially reduces to a kind of behaviourism plus a cardinality constraint on the number of relations holding between mental-relevant behaviours. As most functionalists see functionalism as a distinct theory of mind from behaviourism, this suggests that the modified Ramsey sentence cannot form a satisfactory formalism for functionalism.

In principle, there seem to be three main ways in which society can react when people commit crimes under influence of mental illness.(1) The standard model. We excuse them. If they are dangerous they are detained in the interest of safety of the rest of the citizens.(2) The Swedish model. We hold them responsible for their criminal offence, we convict them, but we do not sentence them to jail. Instead, we sentence them to psychiatric treatment.(3) My model. We sentence them (...) to jail, but offer them (voluntary) psychiatric treatment.The advantages of my model are obvious. We get a clear delineation of roles. We allow the psychiatrist to be just a doctor, not a warden. We liberate psychiatry of the objective of deciding whether people who were mentally ill when they committed criminal offences ‘could have acted otherwise’— a hopeless task. We allow that psychiatrists live up to their professional ethical code (the Hawaii Declaration). We treat psychically ill persons as ‘normal’, we allow them to repent their crimes, which renders easier their recovery.However, two objections to my model come to mind. First of all, is it not unfair to sentence people to jail who could not help doing what they did? And, secondly, the question of fairness set to one side, is it not inhumane to sentence mentally ill persons to jail? Is it not inhumane to the mentally ill persons themselves, and does it not mean that they will be a burden to other prisoners?In my paper I show that, if our system of criminal punishment takes a civilised form, neither of these objections carries any weight.

There is now considerable evidence that human sentence processing is expectation based: As people read a sentence, they use their statistical experience with their language to generate predictions about upcoming syntactic structure. This study examines how sentence processing is affected by readers' uncertainty about those expectations. In a self-paced reading study, we use lexical subcategorization distributions to factorially manipulate both the strength of expectations and the uncertainty about them. We compare two types of uncertainty: uncertainty about the verb's complement, reflecting (...) the next prediction step; and uncertainty about the full sentence, reflecting an unbounded number of prediction steps. We find that uncertainty about the full structure, but not about the next step, was a significant predictor of processing difficulty: Greater reduction in uncertainty was correlated with increased reading times. We additionally replicated previously observed effects of expectation violation, orthogonal to the effect of uncertainty. This suggests that both surprisal and uncertainty affect human RTs. We discuss the consequences for theories of sentence comprehension. (shrink)

This paper begins with a problem stemming from Hume regarding credences about credences. Suppose one has a credence of .95 in p, and suppose one assesses the credence to be such. But suppose one’s second-order credence in this assessment is less than 1. Then, by a standard conditionalization rule, one’s credence in p becomes less than .95. Moreover, such “erosion” can iterate by considering one’s, third-, fourth-, fifth-order credences, etc. (In light of this, some have rejected higher-order credences; however, it (...) is argued that Lewis’ “Principal Principle” forbids this.) The paper then offers a partial solution by describing circumstances under which a person has reason to assign credence 1 to a first-order credence. The solution takes the form of a “transparency” view of self-knowledge from Parent (2017, chapter 8). Briefly, it is argued that when one “reflex-like” utters a sentence “The probability of p is n”, then as a matter of psychological law, the utterance is an expression of one’s own judgment. The Principal Principle then necessitates that one’s credence in p is n, assuming one is being rational. Thus, upon perceiving such an utterance, one can thereby have a reason to assign a second-order credence of 1. (shrink)

Purpose: So far, the work of Josef Mitterer has not been widely recognized in philosophy of education, even though it offers many points of contact not only for epistemological and methodological questions but also for empirical and educational issues. Among these points of contact there is an outstanding sentence (see motto), which can be taken as a starting point for conceptual considerations in philosophy of education. The article takes this sentence as a hub for some corresponding investigations. Method: The article (...) seeks to make progress in these investigations through reflecting on Mitterer's sentence in ten steps, beginning with translational aspects and ending with questions of power relations and inconsistency. The arguments are made through (a) reference to concepts that are currently being discussed in philosophy of education and constructivist discourses, (b) through contrasting various conceptualizations, and (c) through discussion of selected examples. Findings: The article proposes a translation of Mitterer's sentence that may be from Mitterer. It points out several similarities with and differences to positions related to (presumed) positions of Mitterer. Furthermore, it shows innovative options for argumentations in educational philosophy on that basis. Benefits: The contribution sounds out some interfaces between Mitterer's philosophy and current debates in philosophy of education. It contributes to differentiated understandings of Mitterer's sentence and it opens up a new field of discourse. (shrink)

Jc Beall is known for defending modest dialetheism; this is the view that there are dialetheia, but only in the form of “spandrels” arising otherwise reasonable semantic terminology (e.g., the Liar paradox). Beall also regards his view as modest in partaking of a deflationary view of truth, a view where ‘true’ is a device of disquotational inference which expresses no “substantive property.” Beall supports deflationism by an appeal to Ockham’s razor; however, the premise that ‘true’ is fundamentally disquotational is found (...) dubious. Nonetheless, we can craft an ultra-modest dialetheism which assumes only that at least one utterance of ‘This sentence is not true’ uses ‘true’ as a disquotational device, and maintains neturality on whether it expresses a substantive property. The limited scope of the ultra-modest view will be disappointing to formal semanticists hoping to capture the behavior of ‘true’ throughout the language. But its modest basis gives dialetheism the best hope for wider acceptance in the discipline. (shrink)

Mental fictionalism holds that folk psychology should be regarded as a kind of fiction. The present version gives a Lewisian prefix semantics for mentalistic discourse, where roughly, a mentalistic sentence “p” is true iff “p” is deducible from the folk psychological fiction. An eliminativist version of the view can seem self-refuting, but this charge is neutralized. Yet a different kind of “self-effacing” emerges: Mental fictionalism appears to be a mere “parasite” on a future science of cognition, without contributing anything substantial. (...) The paper then rebuts the objection, illustrating that prefix semantics resolves a lingering problem for eliminativism from Boghossian. The problem is that eliminativists seem unable to adopt realism about neuroscience, for such realism implies that neuroscientific statements *represent* reality accurately. However, a deflationary version of prefix semantics allows the eliminativist to draw an ontologically relevant distinction (roughly) between truths that have a story-telling prefix and those that do not. (Deflationism means there is no implication that the unprefixed sentences robustly represent reality.) The overarching lesson is that eliminativists need to approach to ontology carefully so to avoid self-refutation; however, prefix semantical mental fictionalism provides the resources for them to do so.

We identify a number of principles with respect to prediction that, we argue, underpin adult language comprehension: (a) comprehension consists in realizing a mapping between the unfolding sentence and the event representation corresponding to the real‐world event being described; (b) the realization of this mapping manifests as the ability to predict both how the language will unfold, and how the real‐world event would unfold if it were being experienced directly; (c) concurrent linguistic and nonlinguistic inputs, and the prior internal states (...) of the system, each drive the predictive process; (d) the representation of prior internal states across a representational substrate common to the linguistic and nonlinguistic domains enables the predictive process to operate over variable time frames and variable levels of representational abstraction. We review empirical data exemplifying the operation of these principles and discuss the relationship between prediction, event structure, thematic role assignment, and incrementality. (shrink)

Roy T Cook examines the Yablo paradox--a paradoxical, infinite sequence of sentences, each of which entails the falsity of all others that follow it. He focuses on questions of characterization, circularity, and generalizability, and pays special attention to the idea that it provides us with a semantic paradox that involves no circularity.

Traditional document clustering algorithms consider text-based features such as unique word count, concept count, etc. to cluster documents. Meanwhile, event mining is the extraction of specific events, their related sub-events, and the associated semantic relations from documents. This work discusses an approach to event mining through clustering. The Universal Networking Language -based subgraph, a semantic representation of the document, is used as the input for clustering. Our research focuses on exploring the use of three different feature sets for event clustering (...) and comparing the approaches used for specific event mining. In our previous work, the clustering algorithm used UNL-based event semantics to represent event context for clustering. However, this approach resulted in different events with similar semantics being clustered together. Hence, instead of considering only UNL event semantics, we considered assigning additional weights to similarity between event contexts with event-related attributes such as time, place, and persons. Although we get specific events in a single cluster, sub-events related to the specific events are not necessarily in a single cluster. Therefore, to improve our cluster efficiency, connective terms between two sentences and their representation as UNL subgraphs were also considered for similarity determination. By combining UNL semantics, event-specific arguments similarity, and connective term concepts between sentences, we were able to obtain clusters for specific events and their sub-events. We have used 112 000 Tamil documents from the Forum for Information Retrieval Evaluation data corpus and achieved good results. We have also compared our approach with the previous state-of-the-art approach for Router-RCV1 corpus and achieved 30% improvements in precision. (shrink)

It is shown that the logical truth of instances of the T-schema is incompatible with the formal nature of logical truth. In particular, since the formality of logical truth entails that the set of logical truths is closed under substitution, the logical truth of T-schema instances entails that all sentences are logical truths.

The Siddhāntaleśasaṅgraha written by Appayyadīkshitar in the seventeenth century is one of the rare texts where the author brings together the different views of Advaita present at his time. The book itself starts with the controversy surrounding whether the sentence “śrotavyaḥ…” is a vidhi-vākya or not. This paper attempts to summarize the various approaches to this question in the SLS and gives us a glimpse as to how the debate was conducted. Even though the SLS was translated by Suryanarayana Sastri (...) in 1933 the vocabulary and the style is so out-dated that it was not of much use. I then decided to do a fresh translation of the SLS and have succeeded only in translating the first uddeśa. I have condensed the arguments presented in the SLS under some broad headings and thus tried to recreate the arguments presented in the text. (shrink)

We begin with a prepositional languageLpcontaining conjunction (Λ), a class of sentence names {Sα}αϵA, and a falsity predicateF. We (only) allow unrestricted infinite conjunctions, i.e., given any non-empty class of sentence names {Sβ}βϵB,is a well-formed formula (we will useWFFto denote the set of well-formed formulae).The language, as it stands, is unproblematic. Whether various paradoxes are produced depends on which names are assigned to which sentences. What is needed is a denotation function:For example, theLPsentence “F(S1)” (i.e.,Λ{F(S1)}), combined with a denotation (...) functionδsuch thatδ(S1)“F(S1)”, provides the (or, in this context, a)Liar Paradox.To give a more interesting example,Yablo's Paradox[4] can be reconstructed within this framework.Yablo's Paradoxconsists of an ω-sequence of sentences {Sk}kϵωwhere, for eachnϵω:WithinLPan equivalent construction can be obtained using infinite conjunction in place of universal quantification - the sentence names are {Si}iϵωand the denotation function is given by:We can express this in more familiar terms as:etc. (shrink)

We begin with the idea that lines of reasoning are continuous mental processes and develop a notion of continuity in proof. This requires abstracting the notion of a proof as a set of sentences ordered by provability. We can then distinguish between discrete steps of a proof and possibly continuous stages, defining indexing functions to pick these out. Proof stages can be associated with the application of continuously variable rules, connecting continuity in lines of reasoning with continuously variable reasons. (...) Some examples of continuous proofs are provided. We conclude by presenting some fundamental facts about continuous proofs, analogous to continuous structural rules and composition. We take this to be a development on its own, as well as lending support to non-finitistic constructionism. (shrink)

I propose to examine what I take to be the point at issue between subjectivist and objectivist theories of ethics and to explain that the controversy between them is unreal. It springs from a misunderstanding of the nature of appraisal sentences. What I hope to show is that if such sentences were really analysable in the way in which the critics and many of the supporters of subjectivist theories suppose, then those theories would indeed, as it is sometimes (...) put “fail to do justice to the facts of moral experience.” But it seems to me that objectivist theories are no better off. They make exactly the same mistake though in a more sophisticated way. I therefore propose to see whether any useful results can be achieved by construing appraisal sentences on rather different lines. By appraisal sentences I mean sentences of the form “I approve of …, I think well of …, I commend …, etc.” I shall call these simple appraisals, sentences of the form “… is good, … is meritorious, … is praiseworthy, etc.” I shall call these moral appraisals. In these terms, subjectivist theories assert that moral appraisals can always be expressed without change of meaning by simple appraisals, though perhaps the addition of an imperative sentence of some kind is required to complete the translation. Objectivist theories deny this possibility and claim that moral appraisals assert truths about the independent world and not psychological facts about the speaker. (shrink)

Context: It is beyond doubt that RC has received a great deal of attention in educational studies and learning theory. But overall, the current situation seems to be rather ambivalent in view of the blurring of the various strands in constructivist discourses and the different ways of distinguishing and foregrounding constructivist positions. Correspondingly, there is a wide range of claims, from the claim that (radical) constructivism represents a mainstream endeavor to attributions of its being outdated, self-refuting or irrelevant. Purpose: The (...) paper seeks to sound out the ambivalent situation of (radical) constructivism between “all” and “nothing” by examples of attributions of meaning to constructivist positions in academic everyday life and by challenging both prevalent criticisms of systemic-constructivist pedagogy and widespread broad classifications in learning theory. Method: The article critically reflects on (1) one-sentence “destructions” of constructivist positions, (2) Pongratz’s criticism of systemic-constructivist pedagogy, and (3) the threefold classification of the world of learning, i.e., behaviorism, cognitivism, and constructivism. Results: Both the current criticism of constructivism as a mainstream endeavor and evolutionary suggestions provided by the threefold classification are criticized. Although some constructivist concepts and distinctions are widely accepted today, often these achievements are not recognized as being rooted in constructivist discourses. Implications: As far as mainstreaming constructivism might be related to power politics, selling the “real thing,” and joining the ranks of truth-oriented Isms, it would not appear to be a desirable endeavor for those who rely on viability, circular foundations, relativist philosophy, and relationalist approaches. Nevertheless, clarifications of power relations and the interplay between constructivist analyses of politics and the politics of constructivism might contribute to overcoming the diffuse popularity of constructivist thought towards a better understanding of constructivist contributions to solution oriented, meaningful ways of dealing with urgent problems.

How could the kinds of grammars that linguists write actually be used in models of perceptual processing? This book relates grammars to cognitive architecture. It shows how incremental parsing works, step-by-step, and how specific learning rules might lead to frequency-sensitive preferences.

This chapter introduces several versions of mental fictionalism, along with the main lines of objection and reply. It begins by considering the debate between eliminative materialism (“eliminativism”) versus realism about mental states as conceived in “folk psychology” (i.e., beliefs, desires, intentions, etc.). Mental fictionalism offers a way to transcend the debate by allowing talk of mental states without a commitment to realism. The idea is to treat folk psychology as a “story” and three different elaborations of this are reviewed. First, (...) prefix semantics paraphrases a sentence like ‘Biden believes that Trump lost’ as ‘According to folk psychology, Biden believes that Trump lost’, whereby ontological commitment to belief is avoided. Similarly, pretense theory suggests that we do not assert ‘Biden believes that Trump lost’, but only pretend to assert it. Third, affective theory proposes that such discourse is used in a metaphorical way to understand a person’s affective and dispositional states vis-a-vis the community. The main objections concern whether folk psychology has the features of storytelling, and whether mental fictionalism ends up being self-refuting. The chapter also recaps a less discussed fictionalist view about “qualia” or phenomenal states, and closes by summarizing the papers contained in the volume. (shrink)

A course of dialogical reasoning involving the atheist and the theist reveals a connection between the Curry phenomenon and the step-wise construction of a sound version of the modal ontological argument. The exercise is both adversarial and cooperative as the participants are committed to the norms of shared truth-seeking, respect for one's opponents and a desire to continue the dialectic for as long as possible. The theist relies on the interaction between the properties of a Curry-style sentence and the structure (...) of implication in order to show that the atheist's own commitments imply Anselm's principle (God necessarily exists if He actually exists at all). As Anselm's principle and the possibility premise are the only assumptions required for the modal ontological argument it follows that the theist has, given the norms of the dialogue, a winning strategy against the atheist. This follows since the possibility premise is granted by the atheist as part of their commitment to the norms governing the dialectic though the theist in virtue of those same norms must accept that God is at best maximally perfect in the light of the argument from evil and the Stone paradox.

The natural name theory, recently discussed by Johnson (2018), is proposed as an explanation of pure quotation where the quoted term(s) refers to a linguistic object such as in the sentence ‘In the above, ‘bank’ is ambiguous’. After outlining the theory, I raise a problem for the natural name theory. I argue that positing a resemblance relation between the name and the linguistic object it names does not allow us to rule out cases where the natural name fails to resemble (...) the linguistic object it names. I argue that to avoid this problem, we can combine the natural name theory with a type-realist metaphysics of language, and hold that the name is natural because the name is an instance of the kind that it names. I conclude by reflecting on the importance of the metaphysics of language for questions in the philosophy of language. (shrink)

The Embracing Revenge account of semantic paradox avoids the expressive limitations of previous approaches based on the Kripkean fixed point construction by replacing a single language with an indefinitely extensible sequence of languages, each of which contains the resources to fully characterize the semantics of the previous languages. In this paper we extend the account developed in Cook, Cook, Schlenker, and Tourville and Cook via the addition of intensional operators such as ``is paradoxical''. In this extended framework we are able (...) to characterize the difference between sentences, such as the Liar and the Truth-teller, that receive the same semantic value in minimal fixed points yet seem to involve distinct semantic phenomena.

This article examines cognitive process models of human sentence comprehension based on the idea of informed search. These models are rational in the sense that they strive to find a good syntactic analysis quickly. Informed search derives a new account of garden pathing that handles traditional counterexamples. It supports a symbolic explanation for local coherence as well as an algorithmic account of entropy reduction. The models are expressed in a broad framework for theories of human sentence comprehension.

The author is critical of russell's theory in that his "analysis of sentences containing definite descriptions is very defective" and has too many complications to serve as a "convention for a symbolic language.".

Compiled in the twelfth century A.D. by Chu Hsi, leading exponent of Neo-Confucianism, with the assistance of Lü Tsu-Ch'ien, Chin-ssu Lu serves as a summary of, and introduction to, the vast literature of Neo-Confucian philosophy. Adding a more rational theoretical foundation and new methods of moral cultivation and study to traditional thought and practice, Neo-Confucianism has exercised great influence upon thought and social life in East Asia in the past six hundred years. As the classical statement of this philosophy, this (...) anthology brings together passages from Chou Tun-i, Ch'eng Hao and Ch'eng I, and Chang Tsai on the Way, Learning, and Self-improvement, as well as assessments of the character of Sages and Worthies; also included is a chapter on the doctrines of Buddhism and Taoism, pointing out ways in which they deviated from the Confucian Way. It is a very stimulating work; indeed almost every sentence has spark and substance. Although it has been widely studied by East Asian scholars, so far in the West there has been only the translation into German by Father Olaf Graf, now virtually unobtainable. With his mastery of Chinese philosophical literature, his industriousness in research and his augmentation of the text by generous quotations from the Chinese, Japanese, and Korean commentaries, the translator has achieved extraordinary success in making the English version even more comprehensible than the original Chinese.--T.

This presentation of a system of propositional logic is a foundational paper for systems of illocutionary logic. The language contains the illocutionary force operators '' for assertion and ' ' for supposition. Sentences occurring in proofs of the deductive system must be prefixed with one of these operators, and rules of take account of the forces of the sentences. Two kinds of semantic conditions are investigated; familiar truth conditions and commitment conditions. Accepting a statement A or rejecting A (...) commits a person to accepting some statements (the symbol '' marks this value), to rejecting some statements (), and will leave the person uncommitted with respect to others (). Commitment valuations assign the values to sentences of ; such a valuation is conceived as reflecting the beliefs/knowledge of a particular person. This paper explores the relations between truth conditions and commitment conditions, and between semantic concepts defined in terms of these conditions. (shrink)

There is an apparent problem stemming from the factivity of knowledge that seems to afflict both contextualism and subject-sensitive invariantism . 1 In this article, we will first explain how the problem arises for each theory, and then we will propose a uniform resolution.1.

Let O (...) be such a context. So we have ‘K t’ is true in O.Consider a demanding conversational context D . Let S* be a participant in D.

That sentence in turn concerns S's epistemic status at t with respect to the proposition that S has hands. Got it? 4The factivity of ‘knows’ yields the following consequence : ‘K t’ is true in O → hThis metalinguistic factivity claim is licensed by the fact that any sentence of the …. (shrink)

One construal of convergent realism is that for each clear question, scientific inquiry eventually answers it. In this paper we adapt the techniques of formal learning theory to determine in a precise manner the circumstances under which this ideal is achievable. In particular, we define two criteria of convergence to the truth on the basis of evidence. The first, which we call EA convergence, demands that the theorist converge to the complete truth "all at once". The second, which we call (...) AE convergence, demands only that for every sentence in the theorist's language, there is a time at which the theorist settles the status of the sentence. The relative difficulties of these criteria are compared for effective and ineffective agents. We then examine in detail how the enrichment of an agent's hypothesis language makes the task of converging to the truth more difficult. In particular, we parametrize first-order languages by predicate and function symbol arity, presence or absence of identity, and quantifier prefix complexity. For nearly each choice of values of these parameters, we determine the senses in which effective and ineffective agents can converge to the complete truth on an arbitrary structure for the language. Finally, we sketch directions in which our learning theoretic setting can be generalized or made more realistic. (shrink)

Providing empirically supportable instances of ontological emergence is notoriously difficult. Typically, the literature has focused on two possible sources. The first is the mind and consciousness; the second is within physics, and more specifically certain quantum effects. In this paper, I wish to suggest that the literature has overlooked a further possible instance of emergence, taken from the special science of linguistics. In particular, I will focus on the property of truth-evaluability, taken to be a property of sentences as (...) created by the language faculty within human minds (or brains). The claim will not be as strong as to suggest that the linguistic data and theories prove emergence. Rather the dialectical aim here is to say that we have some good reasons (even if not conclusive reasons) to think that the property is emergent. (shrink)

The semantics of tense has received a great deal of attention in the contemporary linguistics, philosophy and logic literatures. This is probably due partly to a renewed appreciation for the fact that issues involving tense touch on certain issues of philosophical importance (viz., determinism, causality, and the nature of events, of time and of change). It may also be due partly to neglect. Tense was noticeably omitted from the theories of meaning advanced in previous generations. In the writings of both (...) Russell and Frege there is the suggestion that tense would be absent altogether from an ideal or scientifically adequate language. (Tense was not the only blemish of natural language to be removed, of course, but tense is a more serious omission than, say, pronouns because it is present in every sentence of the language.) Finally, in recent years there has been a greater recognition of the important role that all of the so-called “indexical” expressions must play in an explanation of mental states and human behavior. Tense is no exception. Knowing that our friend died is cause for mourning, knowing that he dies is just another confirmation of a familiar syllogism. (shrink)

Information‐theoretic complexity metrics, such as Surprisal (Hale, 2001; Levy, 2008) and Entropy Reduction (Hale, 2003), are linking hypotheses that bridge theorized expectations about sentences and observed processing difficulty in comprehension. These expectations can be viewed as syntactic derivations constrained by a grammar. However, this expectation‐based view is not limited to syntactic information alone. The present study combines structural and non‐structural information in unified models of word‐by‐word sentence processing difficulty. Using probabilistic minimalist grammars (Stabler, 1997), we extend expectation‐based models to (...) include frequency information about noun phrase animacy. Entropy reductions derived from these grammars faithfully reflect the asymmetry between subject and object relatives (Staub, 2010; Staub, Dillon, & Clifton, 2017), as well as the effect of animacy on the measured difficulty profile (Lowder & Gordon, 2012; Traxler, Morris, & Seely, 2002). Visualizing probability distributions on the remaining alternatives at particular parser states allows us to explore new, linguistically plausible interpretations for the observed processing asymmetries, including the way that expectations about the relativized argument influence the processing of particular types of relative clauses (Wagers & Pendleton, 2016).

Recent years have seen a surge in accounts motivated by information theory that consider language production to be partially driven by a preference for communicative efficiency. Evidence from discourse production (i.e., production beyond the sentence level) has been argued to suggest that speakers distribute information across discourse so as to hold the conditional per-word entropy associated with each word constant, which would facilitate efficient information transfer (Genzel & Charniak, 2002). This hypothesis implies that the conditional (contextualized) probabilities of linguistic units (...) affect speakers’ preferences during production. Here, we extend this work in two ways. First, we explore how preceding cues are integrated into contextualized probabilities, a question which so far has received little to no attention. Specifically, we investigate how a cue's maximal informativity about upcoming words (the cue's effectiveness) decays as a function of the cue's recency. Based on properties of linguistic discourses as well as properties of human memory, we analytically derive a model of cue effectiveness decay and evaluate it against cross-linguistic data from 12 languages. Second, we relate the information theoretic accounts of discourse production to well-established mechanistic (activation-based) accounts: We relate contextualized probability distributions over words to their relative activation in a lexical network given preceding discourse.
