Visual Lexical Decision

The present study discusses psycholinguistic evidence for a difference between paradigmatic and extraparadigmatic morphology by investigating the processing of Finnish inflected and cliticized words. The data are derived from three sources of Finnish: from single-word reading performance in an agrammatic deep dyslectic speaker, as well as from visual lexical decision and wordness/learnability ratings of cliticized vs. inflected items by normal Finnish speakers. The agrammatic speaker showed awareness of the suffixes in multimorphemic words, including clitics, since he attempted to fill in this slot with morphological material. However, he never produced a clitic — either as the correct response or as an error — in any morphological configuration (simplex, derived, inflected, compound). Moreover, he produced more nominative singular errors for case-inflected nouns than he did for the cliticized words, a pattern that is expected if case-inflected forms were closely associated with their lexical heads, i.e., if they were paradigmatic and cliticized words were not. Furthermore, a visual lexical decision task with normal speakers of Finnish, showed an additional processing cost (longer latencies and more errors on cliticized than on case-inflected noun forms). Finally, a rating task indicated no difference in relative wordness between these two types of words. However, the same cliticized words were judged harder to learn as L2 items than the inflected words, most probably due to their conceptual/semantic properties, in other words due to their lack of word-level translation equivalents in SAVE languages. Taken together, the present results suggest that the distinction between paradigmatic and extraparadigmatic morphology is psychologically real.

Identity Priming

This study investigates the processing consequences of letter connectedness during Arabic visual word recognition. Specifically, this study examined (a) whether there is a processing cost associated with letter connectedness during word-level reading and (b) whether this factor modulates form-level activation among words during lexical access. Experiment 1 tested one-, two-, and three-chunk Arabic words and nonwords in a lexical decision task with masked identity priming. Experiment 2 tested the same stimuli in a lexical decision task with masked form priming, in which prime–target pairs differed by a letter associated with the morphological root. In both experiments, there was a clear processing cost for letter connectedness—one-chunk words had longer processing times than two-chunk words, which had longer processing times than three-chunk words. Comparable processing time differences were also found for nonwords, suggesting that letter connectedness influences Arabic word recognition at a prelexical orthographic processing stage. Furthermore, although reliable priming was found in both the experiments, there was a suggestion that letter connectedness modulated form priming effects (Experiment 2), with the strongest effect for three-chunk word targets. These findings are taken to indicate that letter connectedness is an important factor that should be considered—and controlled for—in examinations of Arabic visual word recognition.

ABSTRACTThis study examined to what extent advanced and beginning readers, including dyslexic readers of Dutch, make use of morphological access units in the reading of polymorphemic words. Therefore, experiments were carried out in which the role of singular root form frequency in reading plural word forms was investigated in a lexical decision task with both adults and children. Twenty-three adult readers, 37 8-year-old children from Grade 3, 43 11-year-old children from Grade 6, and 33 11-year-old dyslexic readers were presented with a lexical decision task in which we contrasted plural word forms with a high versus low frequency of the singular root form. For the adults, it was found that the accuracy and speed of lexical decision is determined by the surface frequency of the plural word form. The frequency of the constituent root form played a role as well, but in the low-frequency plural words only. Furthermore, a strong developmental effect regarding the accuracy and speed of reading plural word forms was found. An effect of plural word form frequency on word identification was evidenced in all groups. The singular root form frequency also had an impact of the reading of the plural word forms. In the normal reading and dyslexic children, plurals with a high-frequency singular root form were read more accurately and faster than plurals with a low singular root frequency. It can be concluded that constituent morphemes have an impact on the reading of polymorphemic words. The results can be explained in the light of a word experience model leaving room for morphological constituency to play a role in the lexical access of complex words as a function of reading skill and experience and word and morpheme frequency.

Henry gave Elsa a kiss give kiss give a kiss We test two approaches to light verb constructions: (1) joint predication in light verb constructions is stored as pre-specified, and their high frequency predicts less processing cost. (2) Joint predication in light verb constructions is built in real-time. The entailed extra-syntactic composition predicts greater cost. Results from a cross-modal lexical decision task show delayed, higher reaction times for light verb constructions, supporting (2), which is consistent with a linguistic architecture that has partly autonomous lexico-semantic storage and processing.

Case mixing is a technique that is used to investigate the perceptual processes involved in visual word recognition. Two experiments examined the effect of case mixing on lexical decision latencies. The aim of these experiments was to establish whether different case mixing patterns would interact with the process of appropriate visual segmentation and phonological assembly in word reading. In the first experiment, case mixing had a greater effect on response times to words when it led to visual disruption of the multi-letter graphemes (MLGs) as well as the overall word shape (e.g. pLeAd), compared to when it disrupted overall word shape only (e.g. plEAd). A second experiment replicated this finding with words in which MLGs represent either the vowel (e.g. bOaST vs. bOAst) or the consonant sound (e.g. sNaCK vs. sNAcK). These results confirm that case mixing can have different effect depending on the type of orthographic unit that is broken up by the manipulation. They demonstrate that graphemes are units that play an important role in visual word recognition, and that manipulation of their presentation by case mixing will have a significant effect on response latencies to words in a lexical decision task. As such these findings need to be taken into account by the models of visual word recognition.

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.

Semantic Properties

Deadjectival nominals with –sa and –mi in Japanese are both phonologically transparent and morphologically decomposable. However, whilst –sa essentially serves to form nouns out of adjectives, –mi forms function as semantic labels with specific meanings. We examined –sa and –mi nominals in three experiments, an eye-movement experiment presenting –sa and –mi forms in sentence contexts and in two word recognition experiments using (primed and unprimed) lexical decision, to investigate the nature of their form-level representations. Whilst the word recognition experiments produced the same pattern of results for –sa and –mi forms, the eye-movement experiment demonstrated clear differences: –mi forms elicited longer reading times compared to –sa forms, except when the particular meanings of –mi forms were contextually licensed. These results show how different semantic properties affect the performance of derived words that have the same type of word level representation.

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).
