ABSTRACTWord production difficulties are well documented in dyslexia, whereas the results are mixed for receptive phonological processing. This asymmetry raises the possibility that the core phonological deficit of dyslexia is restricted to output processing stages. The present study investigated whether a group of dyslexics had word level receptive difficulties using an auditory lexical decision task with long words and nonsense words. The dyslexics were slower and less accurate than chronological age controls in an auditory lexical decision task, with disproportionate low performance on nonsense words. The finding suggests that input processing difficulties are associated with the phonological deficit, but that these difficulties may be stronger above the level of phoneme perception.

Lexical Decisions

This study explores the hypothesis that children identified as having phonological processing problems may have particular difficulty in processing a different accent. Children with speech difficulties (n = 18) were compared with matched controls on four measures of auditory processing. First, an accent auditory lexical decision task was administered. In one condition, the children made lexical decisions about stimuli presented in their own accent (London). In the second condition, the stimuli were spoken in an unfamiliar accent (Glaswegian). The results showed that the children with speech difficulties had a specific deficit on the unfamiliar accent. Performance on the other auditory discrimination tasks revealed additional deficits at lower levels of input processing. The wider clinical implications of the findings are considered.

Abstract This article reports the results of an auditory lexical decision task, testing the processing of phonetic detail of English noun/verb conversion pairs. The article builds on recent findings showing that the frequent occurrence in certain prosodic environments may lead to the storage of prosody-induced phonetic detail as part of the lexical representation. To investigate this question with noun/verb conversion pairs, ambicategorical stimuli were used that exhibit systematic occurrence differences with regard to prosodic environment, as indicated by either a strong verb-bias, e.g., talk (N/V) or a strong noun-bias, e.g., voice (N/V). The auditory lexical decision task tests whether acoustic properties reflecting either the typical or the atypical prosodic environment impact the processing of recordings of the stimuli. In doing so assumptions about the storage of prosody-induced phonetic detail are tested that distinguish competing model architectures. The results are most straightforwardly accounted for within an abstractionist architecture, in which the acoustic signal is mapped onto a representation that is based on the canonical pronunciation of the word.

AbstractTheoretical accounts of Greek compounds argue for a close relation between their stress properties and their underlying structure. Compounds that preserve and receive stress at the same position as their second constituent are analyzed as stem-word constructions, while those that receive antepenultimate stress are viewed as belonging to the stem-stem category. Using an auditory lexical decision task, we examine the effect of stress change on the processing of compounds in the light of existing theoretical linguistic accounts. Although our experimental results do not reach statistical significance, we believe that they are informative of the cognitive status and role of stress in compound processing. Finally, they relate to existing theories of compounding in Greek and reflect the complex interaction of the psycholinguistic effects of stress and the structural properties of these constructions.

Do So

There has been much debate about the role of phonology in reading. This debate has been fuelled, in part, by mixed findings for phonological effects in lexical decision tasks. In the present research we investigated the impact of reader skill on three phonological effects (homophone, homograph, and regularity effects) in a lexical decision task and in a phonological lexical decision task. In both tasks, the more skilled readers showed different patterns of phonological effects from those of the less skilled readers; in particular, less skilled readers showed regularity effects in both tasks whereas more skilled readers did not. We concluded that more skilled readers activate phonology in these tasks but do so more efficiently, with less spurious phonological activation.

Four Blocks

The current research utilizes lexical decision within an oddball ERP paradigm to study early lexical processing. Nineteen undergraduate students completed four blocks of the oddball lexical decision task (Nonword targets among Words, Word targets among Nonwords, Word targets among Pseudowords, and Pseudoword targets among Words). We observed a reliable P3 ERP component in conditions where the distinction between rare and frequent trials could be made solely based on lexical status (Words among Nonwords and Nonwords among Words). We saw a reliable P3 to rare words among frequent pseudowords, but no P3 was observed when participants were asked to detect pseudowords in the context of frequent word stimuli. We argue that this observed modulation of the P3 results is consistent with psycholinguistic literature that suggests that two criteria are available during lexical access when performing a lexicality judgement, a non-lexical criterion that relies on global activation at the word level and a lexical criterion that relies on activation of a lexical representation (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001; Grainger & Jacobs, 1996).
