<p>Although most models of reading development present orthographic knowledge as a more advanced and later developing form of knowledge than phonological knowledge, this dissertation presents a model of the development of orthographic knowledge in which generalized orthographic knowledge, the knowledge of symbol patterns within and across words, develops early, at the same time as phonological knowledge and before lexicalized representations of a whole word. However, because phonological and generalized orthographic knowledge are not fully integrated, phonological knowledge masks orthographic knowledge in typical measures of literacy. </p><p>In study 1 pre-readers' knowledge of the elements that make up words was tested using eye-tracking as a measure of implicit knowledge. We find that pre-reading children as young as 3 have implicit orthographic knowledge regarding the elements that make up words. This supports the prediction that generalized orthographic knowledge develops before lexicalized knowledge. </p><p>In study 2, children's creative spellings were used to gauge children's implicit knowledge of letter patterns in a naturalistic setting. We find that kindergarteners in particular tend to rely on phonology over orthography when the two are in conflict. This supports the hypothesis that phonological knowledge can mask orthographic knowledge.</p><p>In study 3, children were asked to decode non-words and their implicit knowledge of letter patterns was measured using eye tracking. I found that early readers show some implicit knowledge when decoding, This supports the hypothesis that generalized orthographic knowledge can be measured in literacy tasks under certain testing conditions. </p><p>In study 4, children's phonological and orthographic knowledge was tested directly by asking children to sound out and select the best word. Results show that sensitivity to orthographic violations is decreased when phonology is introduced. This is a direct test of the hypothesis that phonological knowledge can mask orthographic knowledge, and findings support this hypothesis. </p><p>These results suggest that pre-readers show generalized orthographic knowledge before lexicalized knowledge and concurrently with phonological knowledge. Furthermore, this generalized orthographic knowledge initially presents itself implicitly, and in many early literacy tasks the orthographic domain is dominated by phonological concerns. Essentially, orthographic and phonological knowledge develop at the same time; however, until children learn to integrate the two dimensions of written language, they rely on one source over the other.</p> / Dissertation

Given the importance of the role of spelling in literacy, it is important to have knowledge of the linguistic features that allow students to be successful spellers. Having phonological, morphological, and orthographic knowledge is essentially important to spell conventionally. In the United States, the standard language is Academic English (AE). African American Vernacular English (AAVE) is considered a deviation from AE, with its own sound system. AAVE is the most widely used form of dialect in the United States. Many students who speak AAVE may have difficulties in producing the correct spelling of AE words. The overall purpose of this study was to provide sixth-grade students, who are speakers of AAVE, with an eight-week intervention in the principles of phonology, morphology, and orthography that would assist them in improving their spelling performance. Students had similar scores on all spelling and dialect pretest measures before the intervention began. The research design was a pretest/posttest/posttest design using waitlist- control. This study included 142 students divided into 14 class sections taught by two teachers. The two teachers provided the intervention to the students. The experimental group consisted of seven classes, and the control group consisted of seven classes. After the first implementation of the intervention, the study was replicated with the control group of students. MANOVA was utilized to determine the effect of the intervention. The intervention produced large effects for the students who received the spelling instruction. The results from the criterion-referenced spelling assessments and a sentence writing task revealed that students who received explicit instruction from the intervention made gains in their spelling performance from pretest/posttest 1/posttest 2 and maintained these gains after being tested eight weeks later. Practical and theoretical recommendations are provided for teachers and researchers. Suggested recommendations include: providing teacher training that will enable teachers to be more linguistically aware of AAVE and its features, making students aware of the difference in the AAVE and the AE sound system, and conducting more research-based studies that will assist speakers of AAVE in literacy and spelling.

Recent studies in the acquisition of a second language (L2) phonology have revealed that orthography can influence, both positively and negatively, the way L2 learners come to establish target-like lexical representations. The majority of these studies, however, involve language pairs relying on a Roman-based script. In comparison, the influence of a foreign or unfamiliar written representation on L2 phonolexical acquisition remains understudied. This dissertation aims to fill this gap. CHAPTER 2 considers the effects of multiple scripts (e.g. Arabic, Cyrillic, Roman-Maltese, etc.) on the acquisition of the Arabic voiceless pharyngeal fricative /ħ/ and the voiceless uvular fricative /χ/ word-initially. Monolingual native speakers of English participated in a set of five word-learning experiments where they were instructed to learn six pairs of minimally contrastive words, each associated with a unique visual referent. In each experiment, a different script configuration was manipulated. After an initial learning phase, participants were then tested on their phonological acquisition of these L2 minimal pairs. Results show significant differences in phonological accuracy between groups of learners exposed to varying degrees of script unfamiliarity. Specifically, complete script foreignness exerted an inhibitory effect on L2 phonolexical acquisition, while semi-foreign scripts exercised differential inhibitory effects based on whether grapheme-phoneme correspondences (GPCs) also activated L1 phonological units. Two follow-up spelling experiments were also conducted in an attempt to find a more intuitive, symbolic representation of these L2 phonemes. While spellers managed to find various ways to symbolically encode /χ/-words from /ħ/-words, when presented in minimal pairs (but not when presented randomly), no form-consistent pattern emerged from their spelling renditions. These spelling experiments nevertheless support the interpretation that L1 GPCs are likely activated in the course of L2 phonological processing. CHAPTER 3 examines the acquisition of another nonnative phonological contrast, that of Japanese singleton/geminate consonants word-medially. In another set of five word-learning experiments manipulating various aspects of unfamiliar scripts (e.g. Hiragana, Roman/Cyrillic blended), it was found that the acquisition of such a length-based contrast was significantly affected by the foreign written input only when the unfamiliar characters encoding the contrast were graphically highlighted (by way of font coloring and underline) or when they did not convey any information about the durational dimension of the L2 contrast (i.e. when both singletons and geminates were represented with a single character, instead of two for the geminates). These inhibitory effects show that learners are susceptible to be confused by small details featured in unfamiliar written representations presented to them in the course of L2 phonoloxical acquisition. Similar to Chapter 2, two follow-up spelling experiments were conducted. Here, spellers failed to symbolically mark a difference between singleton and geminate auditory items, whether they were presented randomly or in minimal pairs. This lack of differentiation in writing suggests that a consonantal singleton/geminate contrast is a priori not so intuitive to native English speakers. The contributions of this dissertation are manifold. First, the present results provide strong evidence that, aside from recognized acoustic and phonological features influencing the acquisition of a second language sound system, extra-linguistic elements such as written representations also contribute to the acquisitional experience of L2 learners. Furthermore, such findings show that exposure to unfamiliar written representations can significantly inhibit the successful creation of target-like phonological representations, an outcome that has thus far not been attested. Second, it provides additional and complementary research in the subfield of L2 acquisition dealing with the interaction of phonological and orthographic knowledge. The work presented here indeed expands the scope of L2 contrasts and script treatments thus far investigated. Third, implications for second language teaching and loanword phonology can be envisaged. Methods geared towards the acquisition of L2 sounds for instance could be designed taking into account the results obtained here, namely, the fact that a foreign written support may not always be beneficial to learners, depending on the degree of familiarity with the L2 writing system.

The aim of this thesis is to investigate the effect of parafoveal information on central word processing. This topic impacts on two controversial areas of research: the allocation of attention during reading, and letter processing during word recognition. Researchers into the role of attention during reading are split into two camps, with some believing that attention is allocated serially to consecutive words and others that it is spread across multiple words in parallel. This debate has been informed by the results of recent experiments that test a key prediction of the parallel processing theory that parafoveal and foveal processing occur concurrently. However, there is a gap in the literature for tightly-controlled experiments to further test this prediction. In contrast, the study of the processing that letters undergo during word recognition has a long history, with many researchers concluding that letter identity is processed only conjointly with letter ‘slot’ position within a word, known as ‘slot-based’ coding. However, recent innovative studies have demonstrated that more word priming is produced from prime letter strings containing letter transpositions than from primes containing letter substitutions, although this work has not been extended to parafoveal letter prime presentations. This thesis will also discuss the neglected subject of how research into these separate topics of text reading and isolated word recognition can be integrated via parafoveal processing. It presents six experiments designed to investigate how our responses to a central word are affected by varying its relationship with simultaneously presented parafoveal information. Experiment 1 introduced the Flanking Letters Lexical Decision task in which a lexical decision was made to words flanked by bigrams either orthographically related or unrelated to the response word; the results indicated that there is parafoveal orthographic priming but did not support the ‘slot-based’ coding theory as letter order was unimportant. Experiments 2-4 involved eye-tracking of participants who read sentences containing a boundary change that allowed the presentation of an orthographically related word in parafoveal vision. Experiment 2 demonstrated that an orthographically related word at position n+1 reduces first-pass fixations on word n, indicating parallel processing of these words. Experiment 4 replicated this result, and also showed that altering the letter identity of word n+1 reduced orthographic priming whereas altering letter order did not, indicating that slot-based coding of letters does not occur during reading. However, Experiment 3 found that an orthographically related word presented at position n-1 did not prime word n, signifying the influence of reading direction on parafoveal processing. Experiment 5 investigated whether the parallel processing that words undergo during text reading conditions our representations of isolated words; lexical decision times to words flanked by bigrams that formed plausible or implausible contexts did not differ. Lastly, one possible cause of the reading disorder dyslexia is under- or over- processing of parafoveal information. Experiment 6 therefore replicated Experiment 1 including a sample of dyslexia sufferers but found no interaction between reading ability and parafoveal processing. Overall, the results of this thesis lead to the conclusion that there is extensive processing of parafoveal information during both reading (indicating parallel processing) and word recognition (contraindicating slot-based coding), and that underpinning both our reading and word recognition processes is the flexibility of our information-gathering mechanisms.

The research reported in this thesis aimed to investigate potential cognitive-linguistic predictors of reading comprehension levels amongst Persian monolingual and Persian-English bilingual primary school children. The Persian orthography, unlike English, is written from right to left. It is cursive and most of the letters change their shape when connecting to letters on one or both sides. The orthography also has the feature of using marks to represent sounds within the language. These marks are not always included in written text, particularly when the text is targeted at more experienced readers. Over 200 school-children in Iran from grades 2 to 5 were given measures of text reading comprehension involving Cloze completion or passages followed by questions. Comprehension levels were compared to scores on measures of language competence, phonological ability, orthographic processing and speed of processing. Analyses indicated that Persian reading comprehension levels, consistent with English models of reading, were predicted by measures of linguistic competence and word decoding, with the latter being predicted by phonological and orthographic processing skills. However, orthographic skills and speed of processing showed predictions of Persian reading comprehension independent of word decoding processes, findings that differed to those predicted from the English-language derived models. These findings were examined among over 150 Persian-English bilingual children in Persian grades 2 to 5 who attending mainstream schools in New Zealand or Australia. These children were being educated in an English medium context, but with Persian as their home language. Analyses of predictors of reading levels verified the findings reported from the monolingual data. In addition, comparisons of good and poor reading comprehenders argued for deficits in either language or word decoding skills to potentially produce different sub-groups of poor readers, with the findings also being consistent with deficits in phonological decoding and/or orthographic processing skills consistent with dual-route or triangle models of literacy learning disabilities. The thesis findings were used to derive a model of Persian reading comprehension similar to the simple view of reading. The findings can also inform the development of cross-language models of reading and global theories of reading comprehension.

This study provides a thorough examination of the role of orthography in promoting first language-based phonological transfer. Specifically, it analyzes the role of auditory-orthographic condition, type of grapheme-to-phoneme correspondence and aspects of phonological memory on shaping transfer. Although, there has been previous work on the role of orthography in the acquisition of second language phonology, not much is known about the factors that shape orthography-induced transfer. In addition, the role of orthography remains to be formalized in the future models of the acquisition of second language phonology. In this experiment, data was elicited via a primary Spanish-based picture-naming task and a secondary Farsi-based non-word repetition phonological memory task. In the picture-naming task, participants were divided into four groups and assigned to four conditions, three with different degrees of exposure to orthography and one auditory condition. The data based on the productions of 40 novice adult English-speaking learners of Spanish, reveal a robust effect of orthography on phonological transfer leading to non-target-like productions at the very beginning stages of second language acquisition. There is also strong evidence that individual grapheme-to-phoneme correspondences differ in the extent to which they trigger phonological transfer. In addition, the findings show that while the presence of orthography at learning or at production induces transfer, the presence of orthography at learning has a stronger effect. The results also indicate some effect for the different aspects of phonological memory, namely, primacy and repetition effects. However, there was no correlation between individual phonological memory and the quantity of transfer. Based on the findings, I argue that when a shared grapheme corresponds to two different phonemes in the learners’ first language and the second language, the less salient the acoustic/phonetic difference between the target language and the first language phonemes, the higher the probability of first language transfer. I also argue for an effect of first language grapheme-to-phoneme frequency on transfer, suggesting that when there is variability in the realization of a particular grapheme in the first language, transfer will be based on the most frequent first language realization. Moreover, based on the findings in this study and previous research on the effect of orthography on second language production, I propose that exposure to orthography may interfere with the establishment of second language phonological categories.

This thesis presents orthographic analyses of selected works of Musorgsky. The thesis argues that more traditional methods, such as voice-leading analysis or set-theory analysis, are, because of their particular historical and stylistic origins, limited in their application to Musorgsky's music and, on this basis, it sets out to demonstrate the value of an orthographic approach. The thesis takes existing orthographic analyses of the music of later transitional, or post-tonal, figures such as Skriabin and Bartók, and extends the application of this approach to an earlier transitional notation and attempts by composers to give cogent articulation to an increasing number of non-traditional pitch structures. The thesis falls into six chapters. The first chapter reviews common perceptions of Musorgsky, especially the notion that his music is somehow technically deficient or limited by a self-didactic eccentricity. It concludes by surveying analytical approaches to Musorgsky's music, and orthographic analyses of Bartók and Skriabin. The second chapter expounds the methodological principles of orthographic analysis. It examines common-practice conventions of orthography and then takes typical orthographic "problems" found in post-common-practice styles in order to show how novel structures are illuminated by the notational friction described above. The chapter concludes with a case study of Brahms's Intermezzo op.118, no 6, which demonstrates how conventions of common-practice notation are sustained in a piece from the central tradition. Chapters Three and Five are dedicated to the analysis of Musorgsky's music. Each takes a work, or selections from a work, leading to a discussion of several related orthographic and tonal issues. The music examined includes selected passages from Boris Godunov and Pictures at an Exhibition, and the entire song cycle Sunless. Several issues arise from these analyses, notably Musorgsky's use of octave symmetry and polymodalism, and his radical conception of relationships between individual chords and prevailing keys. The sixth chapter synthesises these findings and presents a revised view of Musorgsky's tonal thinking and practice, based on his orthography. At the centre of these findings lie key observations concerning the fusion in his music of "functional" and "non-functional" elements. This concluding chapter also speculates on the further potential role of orthographic analytical methods for musics of a traditional nature, especially those of Eastern European traditions.
