Synonymy and the epistemology of linguistics

In Word and Object, Quine argues from the observation that ‘there is no justification for collating linguistic meanings, unless in terms of men's dispositions to respond overtly to socially observable stimulations’ to the conclusion that ‘the enterprise of translation is found to be involved in a certain systematic indeterminacy’. In this paper, I propose to show (1) that Quine's thesis, when properly understood, reveals in the situation of translation no peculiar indeterminacy but merely the ordinary indeterminacy present in any case of empirical investigation; (2) that it is plausible that, because the subject of inquiry is language, we are in a better position with respect to such empirical indeterminacies than we are in other areas of investigation; (3) that, in any case, Quine's arguments are impotent, for they are either contradictory or incoherent; and (4) that Quine is led to his radical conclusions because he confuses a trivial and unexciting indeterminacy, which does obtain, with the striking indeterminacy for which he argues, which does not obtain.

Synonymy and Intra-Theoretical Pluralism

The starting point of this paper is a version of intra-theoretical (logical) pluralism that was recently proposed by Hjortland [2013]. In a first move, I use synonymy-relations to formulate an intuitively compelling objection against Hjortland's claim that, if one uses a single calculus to characterise the consequence relations of the paraconsistent logic LP and the paracomplete logic K3, one immediately obtains multiple consequence relations for a single language and hence a reply to the Quinean charge of meaning variance. In a second move, I explain how a natural generalisation of the notion of synonymy (adapted to the 3-sided sequent-calculus used by Hjortland) can be used to counter this objection, but I also show how the solution can be turned into an equally devastating ‘one logic after all’ type of objection. Finally, I propose the general diagnosis that these problems could only arise in the presence of conceptual distinctions that are too coarse to accommodate coherent pluralist theses. The latter leads to the general methodological recommendation that the conceptual resources used to think and talk about logic should be kept in line with the formal resources that are used to define and describe a logical theory.     

语境同义性逻辑(英文)

众所周知,基于可能世界语义的内涵逻辑由于对意义的刻画过于粗粝而导致了所谓的"超内涵问题"。为了解决超内涵问题,出现了各种超内涵逻辑,其中由Suszko提出的带等词的命题逻辑(SCI)是超内涵逻辑中最基本的一种。本文是对SCI的精炼,其动机是语境同义性论题(CST)。该论题认为,同义性标准具有语境依赖性。基于认知语境主义,我们给出了CST的一个论证。通过将SCI中的二元等词修改为一个三元结构,用来表示两个陈述相对某个语境表达同一命题,我们给出了CST的希尔伯特式公理系统。我们证明了该系统相对一个代数模型类是可靠的和完全的。该代数模型的论域由命题构成,同时附带一组命题上的全等关系,用以刻画相对于语境的命题同一性。我们运用该逻辑部分解决了分析悖论这一困扰逻辑学家多年的问题。与我们之前的基于相同动机的论文[17]相比,本文给出的形式语言更加丰富,从而能够表达不同语境之间以及不同语境的同义性之间的关系。     

Zipf's Law and Avoidance of Excessive Synonymy

Zipf's law states that if words of language are ranked in the order of decreasing frequency in texts, the frequency of a word is inversely proportional to its rank. It is very reliably observed in the data, but to date it escaped satisfactory theoretical explanation. This article suggests that Zipf's law may result from a hierarchical organization of word meanings over the semantic space, which in turn is generated by the evolution of word semantics dominated by expansion of meanings and competition of synonyms. A study of the frequency of partial synonyms in Russian provides experimental evidence for the hypothesis that word frequency is determined by semantics.     

A Quinean Definition Of Synonymy

The main purpose of this paper is to propose and defend anew definition of synonymy. Roughly (and slightly misleadingly), theidea is that two expressions are synonymous iff intersubstitutions insentences preserve the degree of doxastic revisability. In Section 1 Iargue that Quine's attacks on analyticity leave room for such adefinition. The definition is presented in Section 2, and Section 3elaborates on the concept of revisability. The definition is defendedin Sections 4 and 5. It is, inter alia, shown that the definition hasdesired formal properties. In Sections 6 and 7 I briefly comment on,first, the relation of the definition to Quine's later ideas about (stimulus)synonymy, and, second, its relation to a general, interlinguistic, conceptof meaning.     

Analyticity Without Synonymy In Simple Comparative Logic

In this paper I provide some formal schemas for theanalysis of vague predicatesin terms of a set of semantic relations other thanclassical synonymy, includingweak synonymy (as between ``large' and ``huge'),antonymy (as between ``large'and ``small'), relativity (as between ``large'and ``large for a dog'), and a kind ofsupervenience (as between ``large' and ``wide'or ``long'). All of these relationsare representable in the simple comparativelogic CL, in accordance with the basicformula: the more something is F, the more(or less) it is G. I use Carnapianmeaning postulates to define these relationsas constraints on interpretations of theformal language of CL.     

A parallel-process model of mental rotation

It is argued that some of the phenomena identified with analog processes by Shepard can be understood as resulting from a parallel-process algorithm running on a processor having many individual processing elements and a restricted communication structure. In particular, an algorithm has been developed and implemented which models human behavior on Shepard's object rotation and comparison task. The algorithm exhibits computation times which increase linearly with the angle of rotation. Shepard found a similar linear function in his experiments with human subjects. In addition, the intermediate states of the computation are such that if the rotation process were to be interrupted at any point, the object representation would correspond to that of the actual object at a position along the rotation trajectory. The computational model presented here is governed by three constraining assumptions: (a) that it be parallel: (b) that the communication between processors be restricted to immediate neighbors: (c) that the object representation be distributed across a large fraction of the available processors. A method of diagnosing the correct axis of rotation is also presented.     

Synonymy in sentential languages: a pragmatic view

In this note two notions of meaning are considered and accordingly two versions of synonymy are defined, weaker and stronger ones. A new semantic device is introduced: a matrix is said to be pragmatic iff its algebra is in fact an algebra of meanings in the stronger sense. The new semantics is proved to be universal enough (Theorem 1), and it turns out to be in some sense a generalization of Wójcicki's referential semantics (Theorem 3).     

Examining the convergent validity of shared mental model measures

Despite widespread interest in shared mental models (SMMs) within teams and groups and an extensive empirical literature examining SMM?Cperformance links, very little is known about the convergent validity of commonly used measures of SMMs. In this study, two-person teams (n = 96) engaged in a complex flight task and completed three SMM measures: concept mapping, paired ratings, and causal mapping. Task-based sharedness scores were compared across the measures. Analyses were conducted in two ways: using SMMs of actual team members (n = 96 pairs) and using the SMMs of pairs of participants who worked separately but for whom similarity indices were calculated after the study (n = 18,240). The purpose of the latter pairs, coined pseudo-partners, was to create a sample with considerable power to test the convergent validity of the SMM measures. The results call into some question the convergent validity of these task-based SMM measures.     

A componential model for mental addition

A componential model capable of representing simple and complex forms of mental addition was proposed and then tested by using chronometric techniques. A sample of 23 undergraduate students responded to 800 addition problems in a true-false reaction time paradigm. The 800 problems comprised 200 problems of each of four types: two single-digit addends, one single- and one double-digit addend, two double-digit addends, and three single-digit addends. The results revealed that the columnwise product of addends, a structural variable consistent with a memory network retrieval process, was the best predictor of mental addition for each of the four types of problem. Importantly, the componential model allowed estimation of effects of several other structural variables, e.g., carrying to the next column and speed of encoding of digits. High levels of explained variance verified the power of the model to represent the reaction time data, and the stability of estimates across types of problem implied consistent component use by subjects. Implications for research on mental addition are discussed.     

Comprehension strategies in the development of a mental model.

It is generally assumed that the comprehension strategy used in the development of a mental model for narrative texts focuses on information that is relevant to the protagonist. Experiments 1a and 1b confirmed that readers remain sensitive to the location of the protagonist even when strategies based on text-base level representations predict this information should not be active. Experiments 2 and 3 tested the stronger claim that readers adopt the perspective of the protagonist. Ss did not notice information that was contradictory from the perspective of the protagonist unless explicitly instructed to adopt that perspective. It was concluded that, at the level of the mental model, readers focus on information relevant to the protagonist but that they do not adopt the perspective of the protagonist unless characteristics of the text induce such a strategy.     

Migrant mental health: a model for indicators of mental health and health care consumption.

OBJECTIVE: This study explores the relationship between mental health and health care consumption among migrants in the Netherlands. DESIGN: Samples of the Turkish (n = 648), Moroccan (n = 102), and Surinamese (n = 311) populations in Amsterdam were examined. The study tested a hypothesized model of risk factors for psychiatric morbidity, indicators of well-being, and indicators of health care consumption. The model was specified on the basis of information from earlier research on the sample and literature on the topic. The model was tested and refined using structural equation modeling. MAIN OUTCOME MEASURES: Psychiatric morbidity and well-being measures were assessed with the CIDI 1.1 and MOS-sf-36 subscales, respectively. Health care consumption was assessed by the question "Have you ever consulted one or more of these professionals or health care facilities with respect to mental health problems or problems related to alcohol or drugs usage?" RESULTS: The primary result of this study was the confirmation that health care consumption among migrants is predicted by need and predisposition factors, such as health condition and sociodemographic characteristics. In addition, mental health care consumption of migrants is predicted by acculturation characteristics. This result suggests an effect of cultural and migrant-specific factors in help-seeking behavior and barriers to mental health care facilities. CONCLUSIONS: Findings confirm the existence of migrant-specific mechanisms in health care consumption. Mental health care professionals should be aware of these. However, ignoring common ground for interventions unnecessarily creates distance between migrant groups and between migrant and indigenous Dutch groups.     

The stochastic model of mental testing theory and an application

An axiomatization of mental test theory is presented. The presentation deals explicitly with the following concepts: true score, parallel forms, reliability, validity, and combined test score.This project was supported by the Office of Naval Research under Contract N6onr 270-(20) and by the National Science Foundation, Grant NSF G-642. Work now continued under Nonr 1858-(150) and NSF G-22889.     

Working memory components and imagery instructions in the elaboration of a spatial mental model

The paper investigates the involvement of verbal and visuo-spatial working memory during the processing of spatial texts via a dual-task paradigm. Subjects were presented with three texts describing locations from a route perspective, and had either to imagine themselves moving along a route in surroundings or to rehearse verbal information. Concurrently they had to perform a spatial tapping task, an articulatory task, or no secondary task. Performance on a verification test used to assess the product of comprehension showed that the concurrent tapping task impaired performance in the imagery instructions group but not in the repetition instructions group, and caused the beneficial effect of imagery instructions to vanish. This result was not observed with the articulatory task, where interference effects were similar in both instructions groups. Performance on the concurrent tasks confirmed the pattern obtained with the verification test. In addition, results seem partly dependent on the capacity of spatial working memory as measured by the Corsi Blocks Test. We argue that these results clarify the processes of the construction of a spatial mental model, and confirm that the visuo-spatial working memory is involved in mental imagery.     

An empirical study of a logistic mental test model

A logistic model developed by Birnbaum was tested in two ways. First, plots of proportions of subjects in different score categories were examined for consistency with the assumption of a logistic trace line, and especially for departures from the logistic which seemed due to guessing in multiple choice items. The results showed that guessing seemed to have little effect. Second, an attempt was made to predict the obtained score distributions of samples of subjects on six tests from item parameters estimated on independent samples. The fits were good in all cases, despite considerable differences between the tests, and some extremely odd distributions.Thanks are due to the Educational Testing Service for the generous provision of the data upon which Part I of this study and the analysis of the two set I tests was based and to J. Lumsden for the data of the four set II tests. I would also like to thank F. M. Lord and A. Birnbaum for valuable help in the formulation and conduct of the study.At the University of Michigan 1964–65.     

The Michigan infant mental health home visiting model

Selma Fraiberg's pioneering work with infants, toddlers, and families over 40 years ago led to the development of a field in which professionals from multiple disciplines learned to work with or on behalf of infants, very young children, their parents, and the relationships that bind them together. The intent was to promote social and emotional health through enhancing the security of early developing parent–child relationships in the first years of life (Fraiberg, 2018). Called infant mental health (IMH), practitioners from fields of health, education, social work, psychology, human development, nursing, pediatrics, and psychiatry specialize in supporting the optimal development of infants and the developing relationship between infants and their caregivers. When a baby is born into optimal circumstances, to parents free of undue economic and psychological stressors and who are emotionally ready to provide care and nurturing for an infant's needs, an IMH approach may be offered as promotion or prevention, with the goal of supporting new parent(s) in developing confidence in their capacity to understand and meet the needs of the tiny human they are coming to know and care for. However, when parental history is fraught with abandonment, loss, abuse or neglect, or the current environment is replete with economic insecurity, threats to survival due to interpersonal or community violence, social isolation, mental illness, or substance abuse, the work of the IMH therapist may require intervention or intensive treatment and becomes more psychotherapeutic in nature. The underlying therapeutic goal is to create a context in which the baby develops within the environment of a parent's nurturing care without the psychological impingement that parental history of trauma or loss or current stressors such as isolation, poverty, or the birth of a child with special needs, can incur.
