Correction by contrastive focus
'Correction' is the name of a sentence with contrastive focus' the phonological/phonetic realization of which is a single contrastive pitch accent. These sentences predominantly appear in (fictional) dialogues. The first speaker uses grammatical entities against which the next speaker protests with a sentence nearly identical except that it contains a prosodically marked corrective element. This paper makes contrastive focus visible by means of 'KF' (contrastive focus)
Understanding Focus: Pitch, Placement and Coherence
This paper presents a novel account of focal stress and pitch contour in English dialogue. We argue that one should analyse and treat focus and pitch contour jointly, since (i) some pragmatic interpretations vary with contour (e.g., whether an utterance accepts or rejects; or whether it implicates a positive or negative answer); and (ii) there are utterances with identical prosodic focus that in the same context are infelicitous with one contour, but felicitous with another. We offer an account of two distinct pitch contours that predicts the correct felicity judgements and implicatures, outclassing other models in empirical coverage or formality. Prosodic focus triggers a presupposition, where what is presupposed and how the presupposition is resolved depends on prosodic contour. If resolving the presupposition entails the proffered content, then the proffered content is uninteresting and hence the utterance is in-felicitous. Otherwise, resolving the presupposition may lead to an implicature. We regiment this account in SDRT
Quantum Structure of Negation and Conjunction in Human Thought
We analyse in this paper the data collected in a set of experiments performed
on human subjects on the combination of natural concepts. We investigate the
mutual influence of conceptual conjunction and negation by measuring the
membership weights of a list of exemplars with respect to two concepts, e.g.,
'Fruits' and 'Vegetables', and their conjunction 'Fruits And Vegetables', but
also their conjunction when one or both concepts are negated, namely, 'Fruits
And Not Vegetables', 'Not Fruits And Vegetables' and 'Not Fruits And Not
Vegetables'. Our findings sharpen existing analysis on conceptual combinations,
revealing systematic and remarkable deviations from classical (fuzzy set) logic
and probability theory. And, more important, our results give further
considerable evidence to the validity of our quantum-theoretic framework for
the combination of two concepts. Indeed, the representation of conceptual
negation naturally arises from the general assumptions of our two-sector Fock
space model, and this representation faithfully agrees with the collected data.
In addition, we find a further significant deviation and a priori unexpected
from classicality, which can exactly be explained by assuming that human
reasoning is the superposition of an 'emergent reasoning' and a 'logical
reasoning', and that these two processes can be successfully represented in a
Fock space algebraic structure.Comment: 44 pages. arXiv admin note: text overlap with arXiv:1406.235
Grip Force Reveals the Context Sensitivity of Language-Induced Motor Activity during “Action Words
Studies demonstrating the involvement of motor brain structures in language processing typically focus on \ud
time windows beyond the latencies of lexical-semantic access. Consequently, such studies remain inconclusive regarding whether motor brain structures are recruited directly in language processing or through post-linguistic conceptual imagery. In the present study, we introduce a grip-force sensor that allows online measurements of language-induced motor activity during sentence listening. We use this tool to investigate whether language-induced motor activity remains constant or is modulated in negative, as opposed to affirmative, linguistic contexts. Our findings demonstrate that this simple experimental paradigm can be used to study the online crosstalk between language and the motor systems in an ecological and economical manner. Our data further confirm that the motor brain structures that can be called upon during action word processing are not mandatorily involved; the crosstalk is asymmetrically\ud
governed by the linguistic context and not vice versa
