The use theory of meaning and semantic stipulation

According to Horwich’s use theory of meaning, the meaning of a word W is engendered by the underived acceptance of certain sentences containing W. Horwich applies this theory to provide an account of semantic stipulation: Semantic stipulation proceeds by deciding to accept sentences containing an as yet meaningless word W. Thereby one brings it about that W gets an underived acceptance property. Since a word’s meaning is constituted by its (basic) underived acceptance property, this decision endows the word with a meaning. The use-theoretic account of semantic stipulation contrasts with the standard view that semantic stipulation proceeds by assigning the meaning (reference) to W that makes a certain set of sentences express true propositions. In this paper I will argue that the use-theoretic account does not work. I take Frege to have already made the crucial point: "a definition does not assert anything but lays down something ["etwas festsetzt"]” (Frege 1899, 36). A semantic stipulation for W cannot be the decision to accept a sentence containing W or be explained in terms of such an acceptance. Semantic stipulation constitutes a problem for Horwich's use theory of meaning, especially his basic notion of acceptance.

Perception of speech reflects optimal use of probabilistic speech cues

Listeners are exquisitely sensitive to fine-grained acoustic detail within phonetic categories for sounds and words. Here we show that this sensitivity is optimal given the probabilistic nature of speech cues. We manipulated the probability distribution of one probabilistic cue, voice onset time (VOT), which differentiates word initial labial stops in English (e.g., "beach" and "peach"). Participants categorized words from distributions of VOT with wide or narrow variances. Uncertainty about word identity was measured by four-alternative forced-choice judgments and by the probability of looks to pictures. Both measures closely reflected the posterior probability of the word given the likelihood distributions of VOT, suggesting that listeners are sensitive to these distributions.     

What is conscience and why is respect for it so important?

The literature on conscience in medicine has paid little attention to what is meant by the word ‘conscience.’ This article distinguishes between retrospective and prospective conscience, distinguishes synderesis from conscience, and argues against intuitionist views of conscience. Conscience is defined as having two interrelated parts: (1) a commitment to morality itself; to acting and choosing morally according to the best of one’s ability, and (2) the activity of judging that an act one has done or about which one is deliberating would violate that commitment. Tolerance is defined as mutual respect for conscience. A set of boundary conditions for justifiable respect for conscientious objection in medicine is proposed.

Closed- and open-class lexical access in agrammatic and fluent aphasics

Bradley, Garrett, and Zurif (Bradley, Computational distinctions of vocabulary type. Unpublished doctoral dissertation, MIT Press; Cambridge, MA, 1978; Biological studies of mental processes, MIT Press, Cambridge, MA, 1980) have suggested that closed-class word access is normally mediated by a different route than the open-class one, and that the loss of this closed-class route might account for agrammatism. However, in an earlier study ( Gordon & Caramazza, Brain and Language, 15, 143–160, 1982) we were not able to confirm a meaningful difference between closed- and open-class word frequency responsiveness of the type Bradley (unpublished dissertation, 1978) had seemed to find in normal subjects. We have now done a direct comparison of closed-class frequency sensitivity in agrammatic and nonagrammatic aphasics, to directly test Bradley and colleagues' hypotheses and to avoid some of the experimental problems with between-class frequency comparisons. We find that closed-class words behave similarly whether or not the subject is agrammatic. Therefore, the differences between agrammatic and nonagrammatic aphasics must arise at a deeper level (or levels) of lexical processing than the one probed by the frequency sensitivity effect.     

Gradient effects of within-category phonetic variation on lexical access

In order to determine whether small within-category differences in voice onset time (VOT) affect lexical access, eye movements were monitored as participants indicated which of four pictures was named by spoken stimuli that varied along a 0-40 ms VOT continuum. Within-category differences in VOT resulted in gradient increases in fixations to cross-boundary lexical competitors as VOT approached the category boundary. Thus, fine-grained acoustic/phonetic differences are preserved in patterns of lexical activation for competing lexical candidates and could be used to maximize the efficiency of on-line word recognition.     

Voice onset time production and perception in apraxic subjects

This study explored the relationship between the perception and production of voice onset time (VOT) in apraxic subjects. Spectrograms of the words, “bees” and “peas” spoken by apraxic subjects were acoustically analyzed to obtain a measure of VOT. The subjects also identified the initial cognate (“b” or “p”) from synthetically generated speech spanning a voiced to voiceless time continuum. The results suggest that apraxic subjects have production as well as perceptual errors in the voicing feature but no significant relationship was found between the two measures.     

Inhibitory processes in young and older adults in a picture-word task

Abstract

The present study examines changes in healthy young and healthy older adults in the ability to inhibit partially activated information in a picture/word interference paradigm. On each trial, subjects received a cue (i.e., the word PICTURE or WORD) indicating which of two stimuli the subject should attend to in an upcoming picture/word display. the display always contained a superimposed picture and word (e.g., a picture of a DEER with the word TEA printed on it). Following display offset, and depending upon the initial precue, either a test picture (e.g., KETTLE) or a test word (e.g., MOOSE) was presented. the subject's task was to determine as quickly and as accurately as possible whether the test stimulus was related to the cued dimension of the earlier picture/word display. the speed to reject an unrelated test item (e.g., picture of a KETTLE when the precue was PICTURE) that was related to the ignored dimension of the picture/word display (e.g., the word TEA in the picture/word display) was used as an index of the efficiency of the inhibitory system. the results indicated that older adults had more difficulty than younger adults inhibiting a to-be-ignored word when it was related to a picture test item, but did not have more difficulty inhibiting a to-be-ignored picture when it was related to a word test item. the results indicate that an age-related deficit in the control of interfering information is dependent upon the fluency of the processing routes.     

Temporal coordination of phonation and articulation in a case of verbal apraxia: A voice onset time study

A study of voice onset time (VOT) in stop production was undertaken in order to investigate the hypothesis that the voicing feature errors in the speech of an apraxic patient (Sands, E. S., Freeman, F. J., & Harris, K. S. 1978. Brain and Language, 6, 97–105) were related to deficits in temporal coordination of phonation and articulation. Results demonstrated that the VOTs of the apraxic subject differed markedly from those of normal subjects. The apraxic productions did not include voicing lead for voiced stops. Lag times for voiced stops were longer than normal, while those for voiceless stops were shorter than normal, yielding a compression of the two categories and a marked overlap.     

The Role of Speech-Gesture Synchrony in Clipping Words From the Speech Stream: Evidence From Infant Pupil Responses

How do young infants discover that a segment of the sound stream refers to a particular aspect of the visual world around them? Speakers do not enunciate each word separately, even to infants; rather, whattheysayrunstogether. To relate an object (say, an apple) to its referent, infants must notice the interactant's target of attention (the apple) and at the same time single out the word that refers to it as the other person speaks (Lookattheapple!). We contend that caregivers through their actions assist by directing and educating an infant's attention, particularly through the use of a show gesture. The onset/offset, rhythm, tempo, and duration of these show gestures are synchronous with the saying of the words referring to the target objects. Our prior research using eye tracking found that show gestures lead an infant to look at the object presented as the word for it is uttered and that show gestures facilitate word learning. In this research we tested the hypothesis that show gestures also lead to enhanced attentional processing as measured through pupil dilation. Comparing pupil diameters while words were introduced with a show, static, or asynchronous dynamic gesture, we found that pupil dilation occurred for the show gesture condition and was positively correlated with word learning.     

HISTORICAL ASPECTS OF MINDFULNESS AND SELF-ACCEPTANCE IN PSYCHOTHERAPY

We describe some of the historical conditions that made possible Kabat-Zinn’s [(1990). Full catastrophe living: Using the wisdom of your body and mind to face stress, pain, and illness. New York: Delacorte] very successful use of mindfulness in his stress management program. The ground had been prepared by the nonjudgmental acceptance of people and symptoms by Humanistic psychotherapists, and by the increasing assimilation of Buddhist ideas into Western psychology and psychotherapy. In addition the word “mindfulness,” as the translation of the Pali sati, came to refer to both the manualized practice that provides the evidence for its efficacy in the hands of Kabat-Zinn and others, and the more complex process of clear comprehension and recollection that is described in his more discursive writings, and is similar to Ellen Langer’s use of “mindfulness” in her book of that name.

Serial and parallel processing in reading: Investigating the effects of parafoveal orthographic information on nonisolated word recognition

We present a novel lexical decision task and three boundary paradigm eye-tracking experiments that clarify the picture of parallel processing in word recognition in context. First, we show that lexical decision is facilitated by associated letter information to the left and right of the word, with no apparent hemispheric specificity. Second, we show that parafoveal preview of a repeat of word n at word n + 1 facilitates reading of word n relative to a control condition with an unrelated word at word n + 1. Third, using a version of the boundary paradigm that allowed for a regressive eye movement, we show no parafoveal “postview” effect on reading word n of repeating word n at word n – 1. Fourth, we repeat the second experiment but compare the effects of parafoveal previews consisting of a repeated word n with a transposed central bigram (e.g., caot for coat) and a substituted central bigram (e.g., ceit for coat), showing the latter to have a deleterious effect on processing word n, thereby demonstrating that the parafoveal preview effect is at least orthographic and not purely visual.     

The phenomenological role of affect in the Capgras delusion

This paper draws on studies of the Capgras delusion in order to illuminate the phenomenological role of affect in interpersonal recognition. People with this delusion maintain that familiars, such as spouses, have been replaced by impostors. It is generally agreed that the delusion involves an anomalous experience, arising due to loss of affect. However, quite what this experience consists of remains unclear. I argue that recent accounts of the Capgras delusion incorporate an impoverished conception of experience, which fails to accommodate the role played by ‘affective relatedness’ in constituting (a) a sense of who a particular person is and (b) a sense of others as people rather than impersonal objects. I draw on the phenomenological concept of horizon to offer an interpretation of the Capgras experience that shows how the content ‘this entity is not my spouse but an impostor’ can be part of the experience, rather than something that is inferred from a strange experience.

The presumption of movement

The conceptualisation of movement has always been problematical for Western thought, ever since Parmenides declared our incapacity to conceptualise the plurality of change because our self-identical thought can only know an identical being. Exploiting this peculiar feature and constraint on our thought, Zeno of Elea devised his famous paradoxes of movement in which he shows that the passage from a position to movement cannot be conceptualised. In this paper, I argue that this same constraint is at the root of our incapacity to conceptualise the unseen movement at the micro-level and that the aporetic idea of super-position far from opening the gate on a deeper reality is a symptomatic word for this lack of understanding.

Faith Alone: Reflections on an Adverb

In response to critics of his New Testament translation, Luther points out that they simply do not understand the grammar restrictions of language that requires the addition of the word alone in his translation of Paul's letter to the Romans. Luther also points out that they do not understand that alone in this passage is an adverb and not an adjective. This article explores the significance of the word alone (in “faith alone”) when it is considered an adverb as opposed to an adjective. As an adverb, alone resists attempts to manipulate it into a metaphysical principle. Alone as an adverb keeps faith as a living, dynamic relationship that God established and which comes to expression in the celebration of the sacrament.     

Manoeuvring Strategically with Praeteritio

This paper investigates the role that the stylistic device of praeteritio (or paralipsis) can play in arguers’ attempts to reconcile their rhetorical with their dialectical aims by manoeuvring strategically when carrying out particular discussion moves of the dialectical procedure for resolving a dispute. First, attention will be paid to the ways in which praeteritio can be realized in discourse. Next, an analysis is given of the effects the use of praeteritio may have as a result of the presentational means that are employed. This analysis will be used to establish the possibilities for strategic manoeuvring with this device in the different stages of an argumentative discussion. Finally, an indication is given of how the types of strategic manoeuvring that a praeteritio can be instrumental in may derail, and in which violations of the rules for critical discussion such derailed manoeuvrings may result.

The Communicative Experience: Between Inexpressibile and Elusive

This is a commentary on Cornejo’s Intersubjectivity as co-phenomenology: from the holism to the being-in-the-world-with-others, co-phenomenology, in which meaning is defined as a construal of phenomenological experience, not an individual creation, but rather an intersubjective one. In this paper the basic question is how language expresses the world and things and, consequently, what vision of the world is expressed by language and what relationship it creates with the real. Language lives for and by this constant aspiration to say the inexpressible and it tries to express the driving inner movement of the real through references and interlacing, by multiplying the relational threads of meanings. For example, the phonetic gesture performs for the speaker and his listener a certain structuring of experience, a certain modulation of existence. This is a communicative dimension in which meaning is always a process. It is the situation of co-feeling between subjects, in which understanding is achieved, as defined by Cornejo in his essay. Words, vowels, phonemes from this analysis are not only the conceptual and the final sense of words, but also their emotional sense, are ways to sing the world and they represent the emotional essence.

Effects of subphonetic and syllable structure variation on word recognition

This study explored whether natural acoustic variations as exemplified by either subphonetic changes or syllable structure changes affect word recognition processes. Subphonetic variations were realized by differences in the voice-onset time (VOT) value of initial voiceless stop consonants, and syllable structure variations were realized by vowel deletion in initial unstressed syllables in multisyllable words. An auditory identity priming paradigm was used to determine whether the amount of facilitation obtained to a target stimulus in a lexical decision task was affected by the presence of these acoustic variations in a prime stimulus. Results revealed different patterns for the two types of variability as a function of lexical status. In the case of subphonetic variations, shortening of VOT resulted in reduced facilitation for words but not for nonwords, whereas in the case of syllable structure variation, vowel deletion in an unstressed syllable resulted in reduced facilitation for nonwords and increased facilitation for words. These findings indicate that subphonetic variability interferes with word recognition, whereas syllable structure variability does not, and that this effect is independent of the magnitude of the acoustic difference between a citation form and its variant. Furthermore, the results suggest that the lexical status of the target item plays a crucial role in the processing of both types of variability. Results are considered in relation to current models of word recognition.     

Reliability as a virtue

This paper explores what constitutes reliability in persons, particularly intellectual reliability. It considers global reliability, the overall reliability of persons, encompassing both the theoretical and practical realms; sectorial reliability, that of a person in a subject-matter (or behavioral) domain; and focal reliability, that of a particular element, such as a belief. The paper compares reliability with predictability of the kind most akin to it and distinguishes reliability as an intellectual virtue from reliability as an intellectual power. The paper also connects reliability with insight, reasoning, knowledge, and trust. It is argued that insofar as reliability is an intellectual virtue, it must meet both external standards of correctitude and internal standards of justification.
