Word recognition and syntactic attachment in reading: evidence for a staged architecture

In 3 experiments, the author examined how readers' eye movements are influenced by joint manipulations of a word's frequency and the syntactic fit of the word in its context. In the critical conditions of the first 2 experiments, a high- or low-frequency verb was used to disambiguate a garden-path sentence, while in the last experiment, a high- or low-frequency verb constituted a phrase structure violation. The frequency manipulation always influenced the early eye movement measures of first-fixation duration and gaze duration. The context manipulation had a delayed effect in Experiment 1, influencing only the probability of a regressive eye movement from later in the sentence. However, the context manipulation influenced the same early eye movement measures as the frequency effect in Experiments 2 and 3, though there was no statistical interaction between the effects of these variables. The context manipulation also influenced the probability of a regressive eye movement from the verb, though the frequency manipulation did not. These results are shown to confirm predictions emerging from the serial, staged architecture for lexical and integrative processing of the E-Z Reader 10 model of eye movement control in reading (Reichle, Warren, & McConnell, 2009). It is argued, more generally, that the results provide an important constraint on how the relationship between visual word recognition and syntactic attachment is treated in processing models.     

Word form access dyslexia: Understanding the basis of visual reading errors

We report the case of a patient V.E.M. who exhibits the infrequently described syndrome of visual dyslexia. V.E.M. read many single words accurately and rapidly; however, when words were read inaccurately, the majority of responses were alternate real words bearing a strong visual relationship to the target items. A series of observational and experimental investigations of her reading skills revealed that response accuracy was strongly affected by word frequency and mildly affected by concreteness but not influenced by word length, orthographic neighbourhood size, or semantic priming. It is argued that V.E.M.'s visual dyslexia results from a deficit of the visual word form system. More specifically, we propose that this deficit has an “access” quality, with visual word form representations remaining relatively intact despite an impairment in the processes by which these representations are activated. Taking the results of this study together with previous reports of dyslexic patients who make a high proportion of visual paralexic errors, we also suggest that visual dyslexia represents a multicomponent dyslexic syndrome for which phonological impairment and not semantic impairment may be a necessary condition.

Word recognition during reading: The interaction between lexical repetition and frequency

Memory studies utilizing long-term repetition priming have generally demonstrated that priming is greater for low-frequency than for high-frequency words and that this effect persists if words intervene between the prime and the target. In contrast, word-recognition studies utilizing masked short-term repetition priming have typically shown that the magnitude of repetition priming does not differ as a function of word frequency and does not persist across intervening words. We conducted an eyetracking-while-reading experiment to determine which of these patterns more closely resembles the relationship between frequency and repetition during the natural reading of a text. Frequency was manipulated using proper names that were either high-frequency (e.g., Stephen) or low-frequency (e.g., Dominic). The critical name was later repeated in the sentence, or a new name was introduced. First-pass reading times and skipping rates on the critical name revealed robust repetition-by-frequency interactions, such that the magnitude of the repetition-priming effect was greater for low-frequency than for high-frequency names. In contrast, measures of later processing showed effects of repetition that did not depend on lexical frequency. These results are interpreted within a framework that conceptualizes eye-movement control as being influenced in different ways by lexical- and discourse-level factors.     

Word length effect in early reading and in developmental dyslexia

Vocal reaction times were measured in Italian dyslexics and in proficient readers while they read single words. Three groups of control participants (for a total of 79) were tested. All were in the first, second or third grade of elementary school. Nine third graders with a low level of reading ability when assessed by standard reading procedures were also tested. Results indicated that vocal RTs of control participants were faster and less sensitive to word length as a function of age; also, there was a particularly marked change between first and second graders. Dyslexics' vocal RTs and errors were much worse than those of peer control participants and resembled those of first grade controls. It is suggested that normal readers in an orthographically transparent language (Italian) adopt a lexical strategy quite early in their learning. On the contrary, dyslexics seem unable to learn this mode of processing and continue to use a sub-lexical reading procedure.     

False recognition of objects in visual scenes: Findings from a combined direct and indirect memory test

We report an extension of the procedure devised by Weinstein and Shanks (Memory & Cognition 36:1415–1428, 2008) to study false recognition and priming of pictures. Participants viewed scenes with multiple embedded objects (seen items), then studied the names of these objects and the names of other objects (read items). Finally, participants completed a combined direct (recognition) and indirect (identification) memory test that included seen items, read items, and new items. In the direct test, participants recognized pictures of seen and read items more often than new pictures. In the indirect test, participants’ speed at identifying those same pictures was improved for pictures that they had actually studied, and also for falsely recognized pictures whose names they had read. These data provide new evidence that a false-memory induction procedure can elicit memory-like representations that are difficult to distinguish from “true” memories of studied pictures.     

Contextual modulation of reading rate for direct versus indirect speech quotations

In human communication, direct speech (e.g., Mary said: “I’m hungry”) is perceived to be more vivid than indirect speech (e.g., Mary said [that] she was hungry). However, the processing consequences of this distinction are largely unclear. In two experiments, participants were asked to either orally (Experiment 1) or silently (Experiment 2, eye-tracking) read written stories that contained either a direct speech or an indirect speech quotation. The context preceding those quotations described a situation that implied either a fast-speaking or a slow-speaking quoted protagonist. It was found that this context manipulation affected reading rates (in both oral and silent reading) for direct speech quotations, but not for indirect speech quotations. This suggests that readers are more likely to engage in perceptual simulations of the reported speech act when reading direct speech as opposed to meaning-equivalent indirect speech quotations, as part of a more vivid representation of the former.     

Phonology, lexical access in reading, and articulatory suppression: A critical review

Considerable confusion exists in the literature on visual word recognition and reading with respect to the effects of articulatory suppression upon phonological recoding. The authors of a large number of journal articles, chapters, cognitive psychology textbooks, and books devoted to reading processes have concluded that suppression interferes with phonological receding of print and have used this supposed fact as a basis for determining when phonology is involved in various reading tasks. Others have concluded that suppression need not interfere with phonological recoding (e.g. Besner, Davies and Daniels, 1981; Besner and Davelaar, 1982). The present review concludes that a phonological code can be derived from printed English and used for lexical access without interference from suppression. However, operations performed upon a phonological code—e.g. post-assembly phonemic segmentation and deletion, maintenance in working memory—are disrupted by suppression. A review of the literature supports this distinction; some implications of these views are noted.     

Word association and the acquisition of reading

Two studies relating reading ability to word association responses were carried out. The first involved early readers and matched control children from pre-first-grade classes. There were 29 early readers and 29 nonreading controls matched for age, sex, and IQ. The early readers were found to give significantly more paradigmatic, or same-form-class, responses than the controls. The second study related reading ability, mental age, and word association responses in developmentally delayed teen-agers and young adults, and pre-first-grade children who varied in reading ability. With partial correlation reading ability was found to be related to paradigmatic responding, while mental age was not significantly related. These results indicate that reading acquisition may change word association responses in children through a reorganizing process in the lexicon.The authors would like to thank the Halifax and Dartmouth School Boards for their cooperation. We would also like to thank Paul Cable of Special Education, and the principals and teachers: Beth Conrad, Karen Duerdan, Elaine Fram, Peter Montgomery, Wayne Serebrin, and Bill Schipilow. Their help was greatly appreciated. An earlier version of study 1 was presented at the American Psychological Association meeting in Los Angeles, August 1981.     

Word age-of-acquisition effects: a review

This paper reviews research concerned with word age-of-acquisition (AOA) effects in adult word recognition and production. Methodological issues, including the use of multiple regression techniques, are considered first. The pattern of substantive results is presented and is interpreted as indicating that AOA effects are most marked in word production as against word recognition. Possible theoretical interpretations are discussed and future research possibilities are outlined.     

Word recognition in a phonemic dyslexic patient

The systems underlying word recognition were investigated in a single case study of a patient (K.F.) with an acquired dyslexia. His reading performance was related to parts of speech, word frequency and word concreteness, and his reading errors were analysed. There was a very striking difference between his ability to read concrete and abstract words. Furthermore visual errors, which could not be attributed to a deficit at a peripheral level, predominated; phonemic errors did not occur. It is argued that these findings support a dual encoding model of word recognition, the present case illustrating the impairment of the phonemic route, a direct graphemic-semantic route being relatively spared. These findings and interpretation are for the most part consistent with Marshall and Newcombe's (1973) studies of acquired dyslexia. The present findings are discussed in terms of more general theories of word recognition.     

Attachment and early reading: a longitudinal study

The relationship between quality of attachment in infancy and preschooler's reading interests and skills was explored. At 24 months, 77 children and their mothers were tested using the Strange Situation procedure. In a follow-up study 3 years later, 65 mothers completed a questionnaire about the reading interests and skills of their children. Preschool teachers completed a questionnaire about preparatory reading instruction, and the children's intelligence was measured with the Leiden Diagnostic Test. After 3 years, the securely attached children showed more interest in written material than did the insecurely attached children, regardless of their intelligence and the amount of preparatory reading instruction.     

Word reading and picture naming in Italian

Results from two separate norming studies of lexical access in Italian were merged, permitting a comparison of word-reading and picture-naming latencies and the factors that predict each one for an overlapping subsample of 128 common nouns. Factor analysis of shared lexical predictors yielded four latent variables: a frequency factor, a semantic factor, a length factor, and a final factor dominated by frication on the initial phoneme. Age of acquisition (AoA) loaded highly on the first two factors, suggesting that it can be split into separate sources of variance. Regression analyses using factor scores as predictors showed that word reading and picture naming are both influenced by the frequency/AoA factor. The semantics/AoA factor influenced only picture naming, whereas the length and frication factors influenced only word reading. Generalizability of these results to other languages is discussed, including potential effects of cross-language differences in orthographic transparency.     

Word identification in reading and the promise of subsymbolic psycholinguistics

The vast literature concerning printed word identification either contradicts or provides ambiguous support for each of the central hypotheses of dual-process theory, the most widely accepted theory of printed word identification. In contrast, clear, positive support exists for an alternative subsymbolic approach that includes a central role for the process of phonologic coding. This subsymbolic account is developed around a covariant learning hypothesis, derived from a design principle common to current learning algorithms within the subsymbolic paradigm. Where this hypothesis applies, and it may apply broadly, it predicts a common empirical profile of development.     

Word skipping in reading: On the interplay of linguistic and visual factors

An eye movement experiment is reported in which target words of two and four letters were presented in sentences that strongly raised the expectation of a particular word. There were three possible conditions: The expected word was present in the sentence, an unexpected word of the same length was present, or an unexpected word of a different length was present (all continuations were acceptable, but the latter two were difficult to predict). Our first purpose was to test one of the core assumptions of the Extended Optimal Viewing Position model of eye guidance in reading (Brysbaert & Vitu, 1998). This model states that word skipping is primarily a function of the length of the upcoming word. It leads to the prediction that an unpredicted two‐letter word will be skipped more often than a predicted four‐letter word, which is indeed what we observed. Our second aim was to determine if we could obtain an interaction between context predictability and parafoveal word length, by looking at what happens when the length of the parafoveal word does not agree with the length of the expected word. No such interaction was observed although the effects of both word length and predictability were substantial. These findings are interpreted as evidence for the hypothesis that visual and language‐related factors independently affect word skipping.     

Word recognition in a foreign language: A study of speech perception

Models of speech perception have stressed the importance of investigating recognition of words in fluent speech. The effects of word length and the initial phonemes of words on the speech perception of foreign language learners were investigated. English-speaking subjects were asked to listen for target words in repeated presentations of a prose passage read in French by a native speaker. The four target words were either one or four syllables in length and began with either an initial stop or fricative consonant. Each of the four words was substituted 60 times in identical sentence contexts in place of nouns deleted from the original story. The results indicated that four-syllable words were more easily detected than one-syllable words. Contrary to expectation, stop-initial words were not more accurately detected than fricative-initial words. Based on these findings additional considerations that seem needed in order to apply current models of word recognition to naive listeners are discussed.
