Layout attributes and recall
2003
The spatial arrangement of elements such as icons in a computer interface may influence learning the interface. However, the effects of layout organization on users' information processing is relatively little studied so far. The three experiments of this paper examined two attributes of layouts: spatial grouping by proximity and semantic coherence. Learning was assessed by tasks in which 30 participants recalled icon-like items' labels, locations, or both as a series of study-recall trials. The results show that layout organization interacts with task demands. Semantic organization improves recall of labels, and spatial grouping supports recall of locations. When both labels and locations …
Event-related brain potentials of masked repetition and semantic priming while listening to sentences.
2012
We combined for the first time electrophysiological measures and masked priming technique in sentential context, by setting up a cross-modal masked priming paradigm involving the auditory presentation of sentences. ERPs were time-locked to an auditorily presented word that was preceded by a repeated, related or unrelated pattern masked prime. We registered a two-way N400-difference between unrelated and related/repeated primes, followed by a late positive component (LPC) for repetition priming. Related primes appear to facilitate the lexical-semantic processing of the target to the same extent repeated primes do (equally attenuated N400). Repetition priming exerts additional demands (LPC), …
Are coffee and toffee served in a cup? Ortho-phonologically mediated associative priming.
2008
We report three masked associative priming experiments with the lexical decision task that explore whether the initial activation flow of a visually presented word activates the semantic representations of that word's orthographic/phonological neighbours. The predictions of cascades and serial/modular models of lexical processing differ widely in this respect. Using a masked priming paradigm (stimulus onset asynchrony, SOA = 50 ms), words preceded by ortho-phonologically mediated associated “neighbours” ( oveja–MIEL, the Spanish for sheep–HONEY; note that oveja is a phonological neighbour of abeja, the Spanish for bee) were recognized more rapidly than words preceded by an unrelated word p…
A challenging dissociation in masked identity priming with the lexical decision task.
2013
Abstract The masked priming technique has been used extensively to explore the early stages of visual-word recognition. One key phenomenon in masked priming lexical decision is that identity priming is robust for words, whereas it is small/unreliable for nonwords. This dissociation has usually been explained on the basis that masked priming effects are lexical in nature, and hence there should not be an identity prime facilitation for nonwords. We present two experiments whose results are at odds with the assumption made by models that postulate that identity priming is purely lexical, and also challenge the assumption that word and nonword responses are based on the same information. Our e…
A probabilistic approach to learning a visually grounded language model through human-robot interaction
2010
A Language is among the most fascinating and complex cognitive activities that develops rapidly since the early months of infants' life. The aim of the present work is to provide a humanoid robot with cognitive, perceptual and motor skills fundamental for the acquisition of a rudimentary form of language. We present a novel probabilistic model, inspired by the findings in cognitive sciences, able to associate spoken words with their perceptually grounded meanings. The main focus is set on acquiring the meaning of various perceptual categories (e. g. red, blue, circle, above, etc.), rather than specific world entities (e. g. an apple, a toy, etc.). Our probabilistic model is based on a varia…
Le «sentiment» comme facteur sémantique : la «sémantique représentationnelle» entre la «linguistique psychologique» et le formalisme
2016
Psychological linguistics - Heymann Steinthal in Germany (1823-1899) and Aleksandr Potebnia in Russia (1835-1891) - has borrowed from the psychology of its time the model of “representative semantics” according to which meanings are representations (Vorstellungen) connected to words. Within this frame, “feeling” (Gefühl) or “feeling tonality” belongs to the verbal representation, in particular to the semantic mechanism. This is also the case of Karl Otto Erdmann’s (1858-1931) semantics which distinguishes within the meaning a “secondary meaning” (Nebensinn) and a “value of feeling” (Gefühlswert). Within the formalist approach (it deals with the “Russian formalism”, 1914-1929), the analysis …
RDB2OWL
2010
RDB2OWL is a simple approach of mapping relational databases into independently developed OWL ontologies. The approach is based on creating a mapping RDB schema, filling it with mapping information from which SQL scripts are generated that perform the instance-level transformation. We describe the RDB2OWL mapping schema and report on successful application of the technology to the migration of Latvian medical registries data.
Lexico-semantic change: salpuscar ‘to splash’ and variants, a small enigma
2018
Aquest article mostra quin degué ser l’origen del verb salpuscar i la variant salbuscar, sinònim de l’actual esquitar o esquitxar . Subratlla les possibilitats que ofereixen els corpus textuals digitals i la necessitat de tenir present l’estudi contrastiu de llengües (especialment d’atendre l’occità) i la història de la cultura quan es fa semàntica i lexicologia diacròniques del català. Així mateix, s’hi apliquen nocions bàsiques de la semàntica cognitiva en l’estudi del canvi lingüístic. This article shows what must have been the origin of the Catalan verb salpuscar and its variant salbuscar, synonym of the current verb esquitar o esquitxar (‘to splash’). It highlights the possibilities of…

Tarski’s t-scheme as an alleged basis of Montague semantics
2007
My point in this paper is to focus on some details of Alfred Tarski’s writing that in my opinion have not been aptly represented — or aptly rejected — in Richard Montague’s grammar and to agree with those who share Tarski’s view that human language is something uncapturable. The paper consists of two parts, concerning 1) some attempts to formalize the non-declarative utterances, and 2) the limitations of T-scheme and of Montague grammar.
