Can CANISO activate CASINO? Transposed-letter similarity effects with nonadjacent letter positions
2004
Nonwords created by transposing two adjacent letters (i.e., transposed-letter (TL) nonwords like jugde) are very effective at activating the lexical representation of their base words. This fact poses problems for most computational models of word recognition (e.g., the interactive-activation model and its extensions), which assume that exact letter positions are rapidly coded during the word recognition process. To examine the scope of TL similarity effects further, we asked whether TL similarity effects occur for nonwords created by exchanging two nonadjacent letters (e.g., canisoCASINO) in three masked form priming experiments using the lexical decision task. The two nonadjacent transpos…
On the nature of consonant/vowel differences in letter position coding: Evidence from developing and adult readers
2016
In skilled adult readers, transposed-letter effects (jugde-JUDGE) are greater for consonant than for vowel transpositions. These differences are often attributed to phonological rather than orthographic processing. To examine this issue, we employed a scenario in which phonological involvement varies as a function of reading experience: a masked priming lexical decision task with 50-ms primes in adult and developing readers. Indeed, masked phonological priming at this prime duration has been consistently reported in adults, but not in developing readers (Davis, Castles, & Iakovidis, 1998). Thus, if consonant/vowel asymmetries in letter position coding with adults are due to phonological inf…
Are Vowels and Consonants Processed Differently? Event-related Potential Evidence with a Delayed Letter Paradigm
2008
Abstract To investigate the neural bases of consonant and vowel processing, event-related potentials (ERPs) were recorded while participants read words and pseudowords in a lexical decision task. The stimuli were displayed in three different conditions: (i) simultaneous presentation of all letters (baseline condition); (ii) presentation of all letters, except that two internal consonants were delayed for 50 msec (consonants-delayed condition); and (iii) presentation of all letters, except that two internal vowels were delayed for 50 msec (vowels-delayed condition). The behavioral results showed that, for words, response times in the consonants-delayed condition were longer than in the vowel…
Does conal prime CANAL more than cinal? Masked phonological priming effects in Spanish with the lexical decision task.
2005
Evidence for an early involvement of phonology in word identification usually relies on the comparison between a target word preceded by a homophonic prime and an orthographic control (rait-RATE vs. raut-RATE). This comparison rests on the assumption that the two control primes are equally orthographically similar to the target. Here, we tested for phonological effects with a masked priming paradigm in which orthographic similarity between priming conditions was perfectly controlled at the letter level and in which identification of the prime was virtually at chance for both stimulus onset asynchronies (SOAs) (66 and 50 msec). In the key prime-target pairs, each prime differed from the targ…
Does consonant–vowel skeletal structure play a role early in lexical processing? Evidence from masked priming
2017
Published online: 02 November 2017 Is the specific consonant–vowel (CV) letter combination of a word a basic source of information for lexical access in the early stages of processing? We designed two masked priming lexical decision experiments to respond to this question by directly examining the role of CV skeletal structure in written-word recognition. To that aim, each target word was preceded by a one-letter different nonword prime that kept the same CV skeletal structure or not. We also included an identity prime as a control. Results showed faster word identification times in the CV congruent condition than in the CV incongruent condition when a consonant was replaced from the target…
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.
The effects of associative and semantic priming in the lexical decision task.
2001
Four lexical decision experiments were conducted to examine under which conditions automatic semantic priming effects can be obtained. Experiments 1 and 2 analyzed associative/semantic effects at several very short stimulus-onset asynchronies (SOAs), whereas Experiments 3 and 4 used a single-presentation paradigm at two response-stimulus intervals (RSIs). Experiment 1 tested associatively related pairs from three semantic categories (synonyms, antonyms, and category coordinates). The results showed reliable associative priming effects at all SOAs. In addition, the correlation between associative strength and magnitude of priming was significant only at the shortest SOA (66 ms). When prime-t…
Exposure to Androstenes Influences Processing of Emotional Words
2018
This article is part of the Research Topic 'The Importance of Olfaction in Intra- and Interspecific Communication'; International audience; There is evidence that human-produced androstenes affect attitudinal, emotional, and physiological states in a context-dependent manner, suggesting that they could be involved in modulating social interactions. For instance, androstadienone appears to increase attention specifically to emotional information. Most of the previous work focused on one or two androstenes. Here, we tested whether androstenes affect linguistic processing, using three different androstene compounds. Participants (90 women and 77 men) performed a lexical decision task after bei…
A diffusion model account of normal and impaired readers.
2004
Acquired aphasics and dyslexics with even very profound word reading impairments have been shown to perform relatively well on the lexical decision task (e.g., Buchanan, Hildebrandt, & MacKinnon, 1999), but direct contrasts with unimpaired participants data is often complicated by extremely long reaction times for patient data. The dissociation between lexical decision and word naming performance shown by these patients is of theoretical importance, and here we present an analysis of processing underlying the lexical decision task. We are able to determine what aspects of performance are affected by acquired aphasics in the lexical decision task. We fit lexical decision data from aphasic pa…
Letter Position Coding Across Modalities: The Case of Braille Readers
2012
BackgroundThe question of how the brain encodes letter position in written words has attracted increasing attention in recent years. A number of models have recently been proposed to accommodate the fact that transposed-letter stimuli like jugde or caniso are perceptually very close to their base words.MethodologyHere we examined how letter position coding is attained in the tactile modality via Braille reading. The idea is that Braille word recognition may provide more serial processing than the visual modality, and this may produce differences in the input coding schemes employed to encode letters in written words. To that end, we conducted a lexical decision experiment with adult Braille…
