Representation
2020
Representation is a primitive notion of many philosophical theories and of cognitive science. It is assumed as an intuitively understandable label assigned to the functions by which a biological or an artificial agent takes part in the world in an epistemological or a behavioral manner. It is employed to define the conditions for the semantic individuation of the states of the agent. The notion of representation was introduced systematically in the Scholastics’ view of cognition. In modern philosophy, the term is often used as a verb. Representation becomes the function of a class of mental states. In contemporary philosophy, the debate over the semantic individuation of states is intertwin…
Jason Intentional Learning: An Operational Semantics
2013
This paper introduces an operational semantics for defining Intentional Learning on Jason, the well known Java-based implementation of AgentSpeak(L). This semantics enables Jason to define agents capable of learning the reasons for adopting intentions based on their own experience. In this work, the use of the term Intentional Learning is strictly circumscribed to the practical rationality theory where plans are predefined and the target of the learning processes is to learn the reasons to adopt them as intentions. Top-Down Induction of Logical Decision Trees (TILDE) has proved to be a suitable mechanism for supporting learning on Jason: the first-order representation of TILDE is adequate t…
Lexical and conceptual components of stem completion priming in patients with Alzheimer's disease
1999
This study evaluated the hypothesis of dissociation between normal lexical but deficient conceptual repetition priming in patients with Alzheimer's disease (AD). For this purpose, we administered to patients with AD and age-matched normal controls the Stem Completion task. In Experiment 1, the level of word processing during study was manipulated by requiring subjects to count vowels (graphemic condition) or generate meanings (semantic condition) of target words. In Experiment 2, the presentation modality was varied during the study to obtain an intramodal and crossmodal repetition priming. Probably due to a floor effect of performance in the graphemic condition, in Experiment 1, AD patient…
A constructive semantics for non-deducibility
2008
This paper provides a constructive topological semantics for non-deducibility of a first order intuitionistic formula. Formal topology theory, in particular the recently introduced notion of a binary positivity predicate, and co-induction are two needful tools. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
Crossing Modalities: A Cognitive Semantics Perspective on Quoting
2015
Elaborating on Talmy (2007a, forthcoming) and Lampert (2013, 2014), this follow- up study probes into quoting as an attention-and modality-sensitive phenomenon at the interface of speech and writing, taking inaugural addresses from Kennedy to Obama as cases in point. Lexicalized to redirect some attention from a quotation’s referential content to concomitants closely associated with it, quotatives medium-specifically prime speech-internal properties of their targets, animating the ‘other voice’ through prosodic and gestural prompts in face-to-face interactions, while figural prompts demarcate verbatim citations in print. Quotations from pre-scripted videotaped presidential inaugurals reveal…
An introduction to the cognitive therapy of evaluation-[1]
1991
Abstract This paper introduces a new cognitive therapy which is evolving from the theoretical background of general semantics theory. This therapy is being tested since 1985 with several samples, the results being favorable and promising. Nevertheless, only its theoretical rational and clinical background will be introduced. Subsequently, the cognitive therapy of evaluation will be defined, and its main therapeutic ingredients described; finally, its differences and similarities with current cognitive therapies will be highlighted.
A word prediction methodology for automatic sentence completion
2015
Word prediction generally relies on n-grams occurrence statistics, which may have huge data storage requirements and does not take into account the general meaning of the text. We propose an alternative methodology, based on Latent Semantic Analysis, to address these issues. An asymmetric Word-Word frequency matrix is employed to achieve higher scalability with large training datasets than the classic Word-Document approach. We propose a function for scoring candidate terms for the missing word in a sentence. We show how this function approximates the probability of occurrence of a given candidate word. Experimental results show that the proposed approach outperforms non neural network lang…
Defectivitat morfològica i variació sintàctica
2021
This paper discusses a case of parametric variation between Catalan and Spanish that concerns the fronting possibilities within the CP domain (the so-called ÇLeft PeripheryÈ). In particular, attention is paid to Catalan’s weak left peripheral activity, which prevents it from generating sentences that involve a Çmild focalizationÈ pattern very common in Spanish (e.g., «Mucha tontería dice el Gobierno» vs. *«Molta ximpleria diuel Govern»), first noted by Torrego (1980) and further explored by Uriagereka (1988). Interestingly, the same behavior is observed in the v*P domain, which accounts for the fact that VSO sentences (generated through movement of the subject to a specifier position, as Or…
The influence of rTMS over prefrontal and motor areas in a morphological task: grammatical vs. semantic effects
2008
We investigated the differential role of two frontal regions in the processing of grammatical and semantic knowledge. Given the documented specificity of the prefrontal cortex for the grammatical class of verbs, and of the primary motor cortex for the semantic class of action words, we sought to investigate whether the prefrontal cortex is also sensitive to semantic effects, and whether the motor cortex is also sensitive to grammatical class effects. We used repetitive transcranial magnetic stimulation (rTMS) to suppress the excitability of a portion of left prefontal cortex (first experiment) and of the motor area (second experiment). In the first experiment we found that rTMS applied to t…
