Eye movements reveal readers’ lexical quality and reading experience

Two experiments demonstrate that individual differences among normal adult readers, including lexical quality, are expressed in silent reading at the word level. In the first of two studies we identified major dimensions of variability among college readers and among words using factor analysis. We then examined the effects of these dimensions of variability on eye movements during paragraph reading. More experienced readers (who also were higher in reading speed) read words more quickly, especially less frequent words, while readers with higher lexical knowledge showed shorter early fixations, especially for more frequent words. These results suggest that individual differences in reading may reflect differences in the quality of lexical representations and in reading experience, which is a source of lexical quality. In a second study, we controlled the lexical knowledge readers obtained from new words through a training paradigm that varied exposure to a word’s orthographic, phonological, and meaning constituents. Training exposure to orthographic and phonological constituents affected first pass reading measures, and phonological and meaning training affected second pass measures. Incomplete knowledge of word components slowed first pass reading times, compared to both more complete knowledge and no knowledge. Training effects were mediated by individual differences, pointing to lexical quality and reading experience—which, combined reflect reading expertise—as important in word reading as part of text reading.     

Effects of induced orthographic and semantic knowledge on subsequent learning: a test of the partial knowledge hypothesis

Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, also known as “frontier words” (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar. However, studies investigating this question have produced mixed findings, and individual differences in baseline knowledge have complicated results both within and across studies. We present two studies that took a different approach, controlling both familiarity and the nature of the familiarizing episode. We controlled familiarity with novel words through pre-exposure (“pre-familiarization”) in isolation, to induce form-based familiarity, or in sentences that provided few clues to meaning, to induce partial semantic knowledge. The number of pre-exposures varied (0, 1, or 4). After the pre-familiarization phase, we presented the words in several highly informative sentences to support meaning acquisition. Participants included both adults and typically developing children, ages 9–12. Participants’ self-rated familiarity with target words, and their knowledge of the words’ meanings and orthography were each measured at baseline, immediately after learning, and 1 week later. Orthographic and semantic word learning showed contrasting effects of pre-familiarization. For orthographic learning, it was the number, rather than the type, of pre-familiarizations that mattered most. By contrast, the number of pre-familiarizations had little impact on word semantic learning; further, pre-familiarization in low-constraint sentences did not consistently boost subsequent learning. These findings suggest that familiarity with a word prior to instruction does not necessarily improve word-learning outcomes, and they highlight the importance of repeated exposures to high quality contexts for robust word learning.

Reading optimally builds on spoken language: implications for deaf readers

Reading is not merely "language by eye." Rather, it builds fundamentally on primary language processes. For hearing readers, this means that spoken language processes, including phonological processes, are critical to high achievement in reading. We examine the implications of this fact for deaf readers by considering the relationship between language and reading and by reviewing the research on the use of phonology by deaf readers. The research, although mixed in its results, suggests that the use of phonology is associated with higher levels of reading skill among deaf readers. We examine related questions, including the additional semantic and visual strategies available to deaf readers, how some deaf readers gain access to the spoken structure of language, and implications for how to improve reading achievement.     

Phonological codes as early sources of constraint in Chinese word identification: A review of current discoveries and theoretical accounts

A written Chinese character has a more direct connection with its meaning than a written word in English does. Moreover, because there is no unit in the writing system that encodes single phonemes, grapheme-phoneme mappings are impossible. These unique features have led some researchers to speculate that phonological processing does not occur in visual identification of Chinese words or that meaning is activated earlier than phonology. This hypothesis, however, has been challenged by more recent discoveries that suggest that phonology in Chinese, just as in English, is central to the visual recognition system. The present paper reviews the literature on phonological codes as early sources of constraint in Chinese word identification and considers the specific aspects of phonological and orthographic processing in Chinese that may differ from those in English. It emphasizes that early phonological processes and phonological mediation are two different questions in the identification-with-phonology hypothesis. Mediation and prelexical phonology, two very important concepts in the literature on phonological computation in reading English, are both misleading in Chinese.     

Reading Ability: Lexical Quality to Comprehension

The lexical quality hypothesis (LQH) claims that variation in the quality of word representations has consequences for reading skill, including comprehension. High lexical quality includes well-specified and partly redundant representations of form (orthography and phonology) and flexible representations of meaning, allowing for rapid and reliable meaning retrieval. Low-quality representations lead to specific word-related problems in comprehension. Six lines of research on adult readers demonstrate some of the implications of the LQH. First, large-scale correlational results show the general interdependence of comprehension and lexical skill while identifying disassociations that allow focus on comprehension-specific skill. Second, word-level semantic processing studies show comprehension skill differences in the time course of form-meaning confusions. Studies of rare vocabulary learning using event-related potentials (ERPs) show that, third, skilled comprehenders learn new words more effectively and show stronger ERP indicators for memory of the word learning event and, fourth, suggest skill differences in the stability of orthographic representations. Fifth, ERP markers show comprehension skill differences in meaning processing of ordinary words. Finally, in text reading, ERP results demonstrate momentary difficulties for low-skill comprehenders in integrating a word with the prior text. The studies provide evidence that word-level knowledge has consequences for word meaning processes in comprehension.     

Word learning: An ERP investigation of word experience effects on recognition and word processing

Adults of varying reading comprehension skill learned a set of previously unknown rare English words (e.g., gloaming) in three different learning conditions in which the type of word knowledge was manipulated. The words were presented in one of three conditions: (1) orthography-to-meaning (no phonology); (2) orthography-to-phonology (no meaning); and (3) phonology-to-meaning (no orthography). Following learning, participants made meaning judgments on the learned words, familiar known words, and unpresented (unlearned) rare words while their ERPs were recorded. The behavioral results showed no significant effects of comprehension skill on meaning judgment performance. Contrastingly, the ERP results indicated comprehension skill differences in P600 amplitude; high-skilled readers showed stronger familiarity effects for learned words, whereas less-skilled readers did not distinguish between learned words, familiar words, and unlearned words. Evidence from the P600 and N400 illustrated superior learning of meaning when meaning information was coupled with orthography rather than phonology. These results suggest that the availability of word knowledge (orthography, phonology, and meaning) at learning affects subsequent word identification processes when the words are encountered in a new context.
