Dual Route Model

There has been a lot of attention for the idea that the reading of a single word (visual word recognition) involves a single mechanism only. This mechanism first maps the orthographic input onto a sublexical phonological code via which, in a second step, the lexicon is accessed. This mechanism is called a single route phonological model, and it should be contrasted with a dual route model, which also assumes an orthographic route. This orthographic route maps the orthographic input onto a lexical orthographic code without phonological recoding. In this paper, both the single route phonological and the dual route models were formulated as multinomial processing tree (MPT) models. These two MPT models were applied to the data of two experiments in which the participants (children in Grades 1 and 2) had to give a combined naming and lexical decision response to four types of stimuli (words and three types of nonwords). The dual route model gave a much better explanation of these data than the single route phonological model.

The Relationship

This article examines the relationship between eye movements and word recognition, moving from what we know about isolated word recognition to the reading of text. There are clear points of contact between behaviour in laboratory tasks with isolated words and word recognition in text; for instance, Schilling et al. (1998) have shown consistent word frequency effects in naming, lexical decision, and fixation times in silent reading. However, there are also major differences between these two domains. Radach and Kennedy (2004) cite “integration with work on single word recognition” as an issue for future reading research. Equally, though, research on isolated visual word recognition can benefit from a consideration of normal reading; when a word is processed in isolation, its normal context has been replaced by a “null” context. The article concentrates on some of the anatomical and computational principles governing access to the mental lexicon. First, it considers eye movements in reading isolated words and then explores how fixation in word recognition is controlled. Finally, the article discusses the issues raised by binocularity.

Interlingual Homographs

Abstract Previous studies on bilingual visual word recognition have been mainly based on European participants, while less is understood about Asian populations. In this study, the recognition of German-English cognates and interlingual homographs in lexical decision tasks was examined in the two non-native languages of Cantonese-English-German trilinguals. In the L2 English task, cognates were reacted to faster and more accurately than their matched non-cognates, while in the equivalent L3 German task, no cognate facilitation effect was found. However, cognate facilitation effects on response time and accuracy were observed in another L3 German task including cognates and interlingual homographs. The study suggests that Asian trilinguals access L2 and L3 in a language non-selective manner, despite their low proficiency in the recently acquired L3. Meanwhile, lexical processing in a non-proficient L3 is to a great extent affected by multiple contextual factors.

Dual Route Model

Abstract Two lexical decision experiments were conducted to study the recognition of two-character Chinese monomorphemic and compound words by adult native Chinese readers. In Experiment 1, the words appeared non-spaced, whereas in Experiment 2 a space was inserted between the two characters. An interaction between word type and spacing reflects a trend for spacing to slow down the recognition of monomorphemic words and speed up that of compound words. The word frequency effect was steeper for monomorphemic than compound words. The number of strokes in the first and the second character influenced the recognition time for compound words, but not for monomorphemic words. The results are interpreted in the light of the parallel dual route model of morphological processing. The holistic route is more prevalent in recognizing Chinese monomorphemic, while the morphological decomposition route is more prevalent in processing Chinese compound words.

We evaluated the dual route cascaded (DRC) model of visual word recognition using Greek behavioural data on word and nonword naming and lexical decision, focusing on the effects of syllable and bigram frequency. DRC was modified to process polysyllabic Greek words and nonwords. The Greek DRC and native speakers of Greek were presented with the same sets of word and nonword stimuli, spanning a wide range on several psycholinguistic variables, and the sensitivity of the model to lexical and sublexical variables was compared to the effects of these factors on the behavioural data. DRC pronounced correctly all the stimuli and successfully simulated the effects of frequency in words, and of length and bigram frequency in nonwords. However, unlike native speakers of Greek, DRC failed to demonstrate sensitivity to word length and syllabic frequency. We discuss the significance of these findings in constraining models of visual word recognition.

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.
