The effects of training in letter-sound correspondences and phonemic decoding (segmenting and blending skills) on three kindergartners' word recognition abilities were examined using a single-subject multiple-baseline design across behaviors and subjects. Whereas CVC pseudowords were trained, generalization to untrained CVC pseudowords, untrained CVC real words, untrained CV and VC pseudowords, and untrained CV and VC real words were assessed. Generalization occurred to all of the untrained constructions for two of the three subjects. The third subject did not show the same degree of generalization to VC pseudowords and real words; however, after three training sessions, this subject read all VC constructions with 100% accuracy. Findings are consistent with group training studies that have shown the benefits of decoding training on word recognition and spelling skills and with studies that have demonstrated the effects of generalization to less complex structures when more complex structures are trained.

Abstract This study investigates the productive use of semantic and phonetic radicals for Chinese character decoding by Chinese as a foreign language (CFL) learners at different levels of L2 proficiency, focusing on the application of radical knowledge according to the learners’ L1 language families. Using a pseudo-word test developed by Williams, Clay. 2014. The development of intra-character radical awareness in L1 Chinese children: Changing strategies. Journal of the Chinese Language Teachers Association 49(2). 1–26 to measure subject preference for semantic versus phonological decoding processes, subjects are asked to match a provided definition and pronunciation with a character in a multiple choice format which included two pseudo characters designed with radicals which corresponded with the provided definition or pronunciation, respectively. The results demonstrate that reliance on semantic or phonological radicals for character identification varies according to the L1 of the CFL learners; subjects whose L1 is relatively orthographically transparent predominantly make use of phonological processing strategies at all levels of proficiency, whereas those whose L1 are more orthographically opaque demonstrate more malleable processing preferences, with relatively strong semantic radical reliance in the early stage of their language learning, and considerable variability between semantic and phonological processing at intermediate and advanced proficiency levels. The findings suggest that developmental trends of using radical decoding strategies differ among CFL learner groups with varying L1 literacy strategy preferences.

Deficit Theory

Although the dominant approach posits that developmental dyslexia arises from deficits in systems that are exclusively linguistic in nature (i.e., phonological deficit theory), dyslexics show a variety of lower level deficits in sensory and attentional processing. Although their link to the reading disorder remains contentious, recent empirical and computational studies suggest that spatial attention plays an important role in phonological decoding. The present behavioral study investigated exogenous spatial attention in dyslexic children and matched controls by measuring RTs to visual and auditory stimuli in cued-detection tasks. Dyslexics with poor nonword decoding accuracy showed a slower time course of visual and auditory (multisensory) spatial attention compared with both chronological age and reading level controls as well as compared with dyslexics with slow but accurate nonword decoding. Individual differences in the time course of multisensory spatial attention accounted for 31% of unique variance in the nonword reading performance of the entire dyslexic sample after controlling for age, IQ, and phonological skills. The present study suggests that multisensory “sluggish attention shifting”—related to a temporoparietal dysfunction—selectively impairs the sublexical mechanisms that are critical for reading development. These findings may offer a new approach for early identification and remediation of developmental dyslexia.
