Revival of local masking traditions in Latvia as the result of cooperation between performers and researchers:

2012

At a time when it is possible to identify oneself with the global and universal, an opposite process is also occurring: an increase in interest in the local. This article describes the process of renewing three previously interrupted traditions. Is it possible to reconstruct a tradition at all, and what are the general conditions of cooperation between the researchers and participants to ensure a successful process? *** V casu, ko se je mogoce poistovetiti z globalnim in univerzalnim, se pojavlja tudi nasprotni proces – porast zanimanja za lokalno. V razpravi avtorica opise proces obnavljanja treh predhodno prekinjenih tradicij in se sprasuje, ali je mogoce rekonstruirati tradicijo in v kat…

Sequential Effects of Phonological Priming in Visual Word Recognition

2005

International audience; Two masked priming experiments were conducted to examine phonological priming of bisyllabic words in French, and in particular, whether it operates sequentially or in parallel. Bisyllabic target words were primed by pseudowords that shared either the first or the second phonological syllable of the target. Overlap of the first syllable only-not the second-produced facilitation in both the lexical decision and the naming tasks. These findings suggest that, for polysyllabic words, phonological codes are computed sequentially during silent reading and reading aloud.

Influence of water sample storage protocols in chemiluminescence detection of trace elements.

2002

This paper shows the influence of different sample storage protocols, on the chemiluminescence signal of some metal ions. The storage protocols studied were: acid addition (HCl or HNO(3)) and no reagent addition to filtered and refrigerated (T=4 degrees C) samples. Light emission was produced for the chemiluminescence reaction between luminol and hydrogen peroxide in buffer carbonate conditions (pH 10.8) catalysed by Cr(III), Co(II) and Cu(II). Batch and/or flow modes in different conditions were tested. Fe(II), Fe(III), Ni(II) and Mn(II) did not give chemiluminescence in the studied conditions. A parallel study of sensitivity and selectivity was performed. Then the presence or absence of t…

Diffractive optics for quasi-direct space-to-time pulse shaping.

2008

The strong chromatic behavior associated with a conventional diffractive lens is fully exploited to propose a novel optical device for pulse shaping in the femtosecond regime. This device consists of two optical elements: a spatially patterned circularly symmetric mask and a kinoform diffractive lens, which are facing each other. The system performs a mapping between the spatial position of the masking function expressed in the squared radial coordinate and the temporal position in the output waveform. This space-to-time conversion occurs at the chromatic focus of the diffractive lens, and makes it possible to tailor the output central wavelength along the axial location of the output point…

No-Reference 3D Mesh Quality Assessment Based on Dihedral Angles Model and Support Vector Regression

2016

International audience; 3D meshes are subject to various visual distortions during their transmission and geometrical processing. Several works have tried to evaluate the visual quality using either full reference or reduced reference approaches. However, these approaches require the presence of the reference mesh which is not available in such practical situations. In this paper, the main contribution lies in the design of a computational method to automatically predict the perceived mesh quality without reference and without knowing beforehand the distortion type. Following the no-reference (NR) quality assessment principle, the proposed method focuses only on the distorted mesh. Specific…

Online assessment of strategic reading literacy skills

2015

This study investigates the possibility of assessing strategic reading literacy skills with computers. The critical value of this assessment is the recording of online indices of the reader's behavior that can be interpreted in terms of strategies. The study uses materials of a standardized paper-and-pencil reading literacy test called CompLEC (Llorens et?al., 2011) and a technology called Read&Answer (Vidal-Abarca et?al., 2011) that presents texts and questions with a masking procedure that allows the recording of reading time and readers' actions to develop a computer-based version called e-CompLEC. We found that reliability and validity of the two versions are largely equivalent, and tha…

Breaking down the word length effect on readers’ eye movements

2015

Previous research on the effect of word length on reading confounded the number of letters (NrL) in a word with its spatial width. Consequently, the extent to which visuospatial and attentional-linguistic processes contribute to the word length effect on parafoveal and foveal vision in reading and dyslexia is unknown. Scholars recently suggested that visual crowding is an important factor for determining an individual’s reading speed in fluent and dyslexic reading. We studied whether the NrL or the spatial width of target words affects fixation duration and saccadic measures in natural reading in fluent and dysfluent readers of a transparent orthography. Participants read natural sentences …

Saccadic eye movements: what do they tell us about aging cognition?

2016

ABSTRACTAlthough the relationship between age-related cognitive decline and saccadic eye movement (SEM) deficits has been outlined, specific cognitive alterations underlying age-related changes in saccadic performance remain unclear. This study attempted to better understand the nature of aging effects on SEMs. We compared SEMs in younger and older adults in prosaccade (PS) and antisaccade (AS) tasks under gap, step, and overlap conditions. We also examined relationships between these performances and several neuropsychological scores. Twenty-eight younger adults (YA), 24 older adults under 65 years (OA 65) of age completed a neuropsychological evaluation, PS and AS tasks. Our results showe…

Does Tonal Information Affect the Early Stages of Visual-Word Processing in Thai?

2014

Thai offers a unique opportunity to investigate the role of lexical tone processing during visual-word recognition, as tone is explicitly expressed in its script. In order to investigate the contribution of tone at the orthographic/phonological level during the early stages of word processing in Thai, we conducted a masked priming experiment—using both lexical decision and word naming tasks. For a given target word (e.g., ห้อง/hᴐ:ŋ2/, room), five priming conditions were created: (a) identity (e.g., ห้อง/hᴐ:ŋ2/), (b) same initial consonant, but with a different tone marker (e.g., ห่อง/hᴐ:ŋ1/), (c) different initial consonant, but with the same tone marker (e.g., ศ้อง/sᴐ:ŋ2/), (d) orthograph…
