When WORDS with Higher-frequency Neighbours Become Words with No Higher-frequency Neighbour (Or How to Undress the Neighbourhood Frequency Effect)
2000
Abstract “SATOR AREPO TENET OPERA ROTAS” (The ploughman, with his plough, manages the work) The influence of lexical similarity on word recognition has been discussed not only because of its theoretical impact but also because it is difficult to replicate. Among the multiplicity of the causes of this inconsistency one reason can be that different words were used in comparing words with higher-frequency neighbours (HFN) and words without HFN. In this experiment we chose French words for which the neighbourhood changes when they are written in UPPER case or in lower case. For example ‘DEFI’ has one HFN (‘DEMI’) but when it is displayed in lower case ‘defi’ has no HFN because ‘demi’ has no acc…
The effects of inter-letter spacing in visual-word recognition: Evidence with young normal readers and developmental dyslexics
2012
Abstract Recent research has demonstrated that slight increases of inter-letter spacing have a positive impact on skilled readers' recognition of visually presented words. In the present study, we examined whether this effect generalises to young normal readers and readers with developmental dyslexia, and whether increased inter-letter spacing affects the reading times and comprehension of a short text. To that end, we conducted a series of lexical decision and continuous reading experiments in which words were presented with the default settings or with a small increase in inter-letter spacing. Increased spacing produced shorter word identification times not only with adult skilled readers…
Where is the syllable priming effect in visual word recognition?
2003
Recent studies using the masked priming paradigm have reported facilitating effects of syllable primes in French and English word naming (Ferrand, Segui, & Grainger, 1996; Ferrand, Segui, & Humphreys, 1997). However, other studies have not been able to replicate these effects in Dutch and English (Schiller, 1998, 1999, 2000). In Experiment 1, using the same stimuli and procedure as Ferrand et al. (1996), we did not replicate the syllable priming effect in French. In Experiments 2a and 2b, when prime duration was increased (from 30 to 45 and 60 ms), we did not obtain a syllable priming effect. In Experiment 3, with 60 participants and exactly the same procedure as Ferrand et al. (1996), we a…
How Literacy Shapes Orthographic Processing
2022
La lectura es una habilidad indispensable en nuestra sociedad. Sin ella, no podríamos acceder a la historia, o aprender de nuestros avances y retrocesos. Resulta casi milagroso que el Homo sapiens hiciera unas marcas en una piedra para aumentar drásticamente su capacidad de memoria. Estas marcas en la piedra, que serían lo que ahora llamamos letras, se convirtieron en herramientas. Herramientas que alteran la maquinaria cerebral para conectar las formas visuales con un significado, es decir, para sustentar la lectura. Hoy en día, la lectura es parte de nuestra vida cotidiana hasta tal punto que no nos damos cuenta de su complejidad. Cuando leemos, nuestros ojos saltan de palabra a palabra, …
Drifting through Basic Subprocesses of Reading: A Hierarchical Diffusion Model Analysis of Age Effects on Visual Word Recognition
2016
International audience; Reading is one of the most popular leisure activities and it is routinely performed by most individuals even in old age. Successful reading enables older people to master and actively participate in everyday life and maintain functional independence. Yet, reading comprises a multitude of subprocesses and it is undoubtedly one of the most complex accomplishments of the human brain. Not surprisingly, findings of age-related effects on word recognition and reading have been partly contradictory and are often confined to only one of four central reading subprocesses, i.e., sublexical, orthographic, phonological and lexico-semantic processing. The aim of the present study…
Are go/no-go tasks preferable to two-choice tasks in response time experiments with older adults?
2015
Epub ahead of print 02/11/2015 Recent research has shown that, in response time (RT) tasks, the go/no-go response procedure produces faster (and less noisy) RTs and fewer errors than the two-choice response procedure in children, although these differences are substantially smaller in college-aged adults. Here we examined whether the go/no-go procedure can be preferred to the two-choice procedure in RT experiments with older adults (i.e. another population with slower and more error-prone responding than college-aged individuals). To that end, we compared these response procedures in two experiments with older adults (Mage = 83 years): a visual word recognition task (lexical decision) and a…
The nature of the syllabic neighbourhood effect in French
2006
International audience; We investigated whether and how sublexical units such as phonological syllables mediate access to the lexicon in French visual word recognition. To do so, two lexical decision task (LDT) experiments examined the nature of the syllabic neighbourhood effect. In Experiments 1a and b, the number of higher frequency syllabic neighbours was manipulated while controlling for the first bigram. The results failed to show a pure syllabic neighbourhood effect. In Experiments 2a and b, syllabic neighbourhood and bigram frequency were factorially manipulated. The interaction showed that the syllabic neighbourhood effect was inhibitory when bigram frequency was high, whereas it wa…
