ERP correlates of transposed-letter priming effects: The role of vowels versus consonants
2008
One key issue for any computational model of visual-word recognition is the choice of an input coding scheme for assigning letter position. Recent research has shown that pseudowords created by transposing two letters are very effective at activating the lexical representation of their base words (e.g., relovution activates REVOLUTION). We report a masked priming lexical decision experiment in which the pseudoword primes were created by transposing/replacing two consonants or two vowels while event-related potentials were recorded. The results showed a modulation of the amplitude at an early window (150-250 ms) and at the N400 component for vowels but not for consonant transpositions. In ad…
ERP correlates of transposed-letter similarity effects: Are consonants processed differently from vowels?
2007
Recent research has shown that pseudowords created by transposing letters are very effective for activating the lexical representation of their base words (e.g., relovution activates REVOLUTION). Furthermore, pseudoword transpositions of consonants are more similar to their corresponding base words than the transposition of vowels. We report one experiment using pseudowords created by the transposition of two consonants, two vowels, and their corresponding control conditions (i.e., the replacement of two consonants or two vowels) in a lexical decision task while Event Related Potentials (ERPs) were recorded. The results showed a modulation of the amplitude of the N400 component as a functio…
Morphological priming involves more than orthographic priming
2007
Los resultados de investigaciones recientes en reconocimiento visual de palabras apoyan cierta autonomía de las unidades morfológicas. Con el fin de investigar si los efectos de priming morfológico están producidos más por el solapamiento de forma que por las relaciones morfológicas de las palabras, se presenta un experimento de decisión léxica con priming enmascarado. Se comparan, mediante la utilización de las mismas palabras test (NUEVO), dos condiciones experimentales relativas a relaciones netamente ortográficas (nueve) y a relaciones morfológicas basadas en la marca de género (nueva). Los resultados de este estudio muestran que las palabras precedidas por otras con las que comparten u…
Bengali nasal vowels: Lexical representation and listener perception
2022
This paper focuses on the question of the representation of nasality as well as speakers’ awareness and perceptual use of phonetic nasalisation by examining surface nasalisation in two types of vowels in Bengali: underlying nasal vowels (CṼC) and nasalised vowels before a nasal consonant (CVN). A series of three cross-modal forced-choice experiments was used to investigate the hypothesis that only unpredictable nasalisation is stored and that this sparse representation governs how listeners interpret vowel nasality. Visual full-word targets were preceded by auditory primes consisting of CV segments of CVC words with nasal vowels ([tʃɑ̃] for [tʃɑ̃d] ‘moon’), oral vowels ([tʃɑ] for [tʃɑl] ‘un…
Is VIRTU4L larger than VIR7UAL? Automatic processing of number quantity and lexical representations in leet words.
2015
Recent research has shown that leet words (i.e., words in which some of the letters are replaced by visually similar digits; e.g., VIRTU4L) can be processed as their base words without much cost. However, it remains unclear whether the digits inserted in leet words are simply processed as letters or whether they are simultaneously processed as numbers (i.e., in terms of access to their quantity representation). To address this question, we conducted two experiments that examined the size congruity effect (i.e., when comparisons of the physical size of numbers are affected by their numerical magnitudes) in a physical-size judgment task. Participants were presented with pairs of leet words th…
Spoken Word Production
2018
This chapter examines two distinct stages of the production of spoken words: the retrieval of semantic and lexical representations, followed by morphological and phonological processing. In both cases, it summarizes models of lexical representation and lexical selection that have focused on the retrieval of single words. These models agree that different lexical information becomes available at different points in time, with access to semantic and syntactic information preceding access to information about lexical form. The structure of this review reflects this dichotomy. Comprehensive production models must also account for the sequencing and timing of lexical processing in multiword utte…
L2-L1 Translation Priming Effects in a Lexical Decision Task: Evidence From Low Proficient Korean-English Bilinguals
2018
One of the key issues in bilingual lexical representation is whether L1 processing is facilitated by L2 words. In this study, we conducted two experiments using the masked priming paradigm to examine how L2-L1 translation priming effects emerge when unbalanced, low proficiency, Korean-English bilinguals performed a lexical decision task. In Experiment 1, we used a 150 ms SOA (50 ms prime duration followed by a blank interval of 100 ms) and found a significant L2-L1 translation priming effect. In contrast, in Experiment 2, we used a 60 ms SOA (50 ms prime duration followed by a blank interval of 10 ms) and found a null effect of L2-L1 translation priming. This finding is the first demonstrat…
