- Description: Despite increased research interest in recent years in the metalinguistic skills underpinning reading in the Southern Bantu languages, little work has been done on the underlying microlinguistic layer. This refers to the actual mechanical underpinnings of linguistic skills; zooming in on micro-language structures so as to explicate our understanding of how reading works. One such microlinguistic phenomenon is the effect of orthographic neighbours on reading and writing. Research has found predominantly faciliatory neighbourhood effects for English word reading (Andrews, 1997; Siakaluk, Sears & Lupker, 2002; Yarkoni, Balota & Yap, 2008). Specifically, words with more orthographic neighbours have faster response times in lexical decision and naming tasks. However, in languages such as Spanish and French, inhibitory neighbourhood effects are reported (Grainger & Jacobs, 1996; Carreiras, Perea & Grainger, 1997). These findings highlight the language-specific nature of orthographic neighbourhood effects (Andrews, 1997), and the necessity for language- specific investigations of these effects. This thesis investigates the linguistic properties of orthographic neighbours in isiXhosa, thereby developing a database of orthographic neighbourhoods in isiXhosa. Further, this research explores the interaction between orthographic neighbourhood density and neighbourhood frequency with three literacy skills: lexical decision response time, word reading accuracy, and spelling accuracy. Data were collected from 97 isiXhosa grade three learners from five schools in KwaNobuhle Township in the Eastern Cape. A corpus of 170 000 tokens of isiXhosa words (Rees & Randera, 2017) was used to compile a database of orthographic neighbourhoods for 30 real, and 30 pseudowords which ranged in orthographic neighbourhood density and neighbourhood frequency, whilst controlling for word length and word frequency. Using this database, lexical decision, word reading, and spelling tasks were designed and administered to the participants. Findings indicate a significant inhibitory effect of orthographic neighbourhood frequency on spelling accuracy. Words with high neighbourhood frequencies are more likely to be spelt incorrectly. There was no observed effect of orthographic neighbourhoods on lexical decision response time and word reading accuracy. These results are interpreted within connectionist and search models of orthographic processing. Specifically, the findings indicate a partial reliance on lexical processing strategies when spelling. That is, orthographic neighbours compete for lexical access when spelling. Education practitioners may wish to present learners with lists of orthographic neighbours when introducing novel words so as to make explicit the fine grain differences between words in the language. This also means that future research will need to develop a larger repository of orthographic neighbours in isiXhosa that can be made available for pedagogical purposes. , Thesis (MA) -- Faculty of Humanities, Linguistics and Applied Language Studies, 2023

- Description: Despite international research confirming its importance, writing and related metalinguistic skills have often been neglected in comparison to reading in literacy research (Cunningham et al., 2001; Castles & Coltheart, 2004; Nag, 2007; Roman et al., 2009; Zhao et al., 2017). On a national level there are very few studies that have explored the writing aspect of literacy in South Africa, and none that has investigated orthographic knowledge in a Southern Bantu language, such as isiXhosa. In an attempt to address this gap, this thesis explores orthographic knowledge and its components in isiXhosa. In particular, it seeks to investigate the unique predictors of word specific and general orthographic knowledge as well as their role for reading and spelling in isiXhosa while controlling for phonological awareness (PA), rapid automatized naming (RAN), and letter-sound knowledge. Furthermore, the thesis attempts to situate its findings within the main premises of the self-teaching hypothesis and dual route approach to orthographic processing in order to contribute to linguistic theories of reading with cross-linguistic evidence (Jorm & Share, 1983; Share & Jorm, 1987; Share, 1995; Grainger & Ziegler, 2011). A quantitative cross-sectional study was conducted with 140 isiXhosa home language third grade learners in which word specific and general orthographic knowledge tasks were specifically designed. These tasks were administered along with oral reading fluency (ORF), spelling, PA, RAN, and letter-sound knowledge. The findings revealed that letter-sound knowledge and PA contributed the largest variance towards both word specific and general orthographic knowledge. Further, word specific orthographic knowledge and letter-sound knowledge were the only significant predictors of spelling. Similarly, both word specific and letter-sound knowledge were significant predictors of reading, along with RAN and general orthographic knowledge. Quantile linear regression analyses revealed that word specific orthographic knowledge was a robust predictor of spelling and letter-sound knowledge was a robust predictor of reading across ability levels confirming the importance for word specific orthographic knowledge for spelling and letter-sound knowledge for reading in isiXhosa. In relation to the two reading theories considered in this thesis, the findings reflect similarities between the assertions of the self-teaching hypothesis and current thesis with suggestions made for further inquiry. The dual route approach to orthographic processing provides insights into the potential processing of orthographic information while reading in isiXhosa. The findings of this study confirm the importance of orthographic knowledge for reading and spelling for languages with transparent orthographies such as isiXhosa. , Thesis (MA) -- Faculty of Humanities, Linguistics and Applied Language Studies, 2022
