Abstract: Dual-route theories of reading posit that a sublexical reading mechanism that operates serially and from left to right is involved in the orthography-to-phonology computation. These theories attribute the masked onset priming effect (MOPE) and the phonological Stroop effect (PSE) to the serial left-to-right operation of this mechanism. However, both effects may arise during speech planning, in the phonological encoding process, which also occurs serially and from left to right. In the present paper, we sought to determine the locus of serial processing in reading aloud by testing the contrasting predictions that the dual-route and speech planning accounts make in relation to the MOPE and the PSE. The results from three experiments that used the MOPE and the PSE paradigms in English are inconsistent with the idea that these effects arise during speech planning, and consistent with the claim that a sublexical serially operating reading mechanism is involved in the print-to-sound translation. Simulations of the empirical data on the MOPE with the dual route cascaded (DRC) and connectionist dual process (CDP++) models, which are computational implementations of the dual-route theory of reading, provide further support for the dual-route account.

Abstract: Theories of reading aloud are silent about the role of subphonemic/subsegmental representations in translating print to sound. However, there is empirical evidence suggesting that feature representations are activated in speech production and visual word recognition. In the present study, we sought to determine whether masked primes activate feature representations in reading aloud using a variation of the masked onset priming effect (MOPE). We found that target nonwords (e.g., BAF) were read aloud faster when preceded by masked nonword primes that shared their initial phoneme with the target (e.g., bez), or primes whose initial phoneme shared all features except voicing with the first phoneme of the target (e.g., piz), compared with unrelated primes (e.g., suz). We obtained the same result in 2 experiments that used different participants and prime durations (around 60 ms in Experiment 1 and 50 ms in Experiment 2). The significant masked feature priming effect that was observed in both experiments converges with the empirical evidence in the speech production and visual word recognition domains indicating a functional role for features in reading aloud. Our findings motivate the further development of current theories of reading aloud and have important implications for extant theories of speech production.

Abstract: In this study, we investigated effects of morphological processing on handwriting production in beginning writers of German. Children from Grades 3 and 4 were asked to copy words from a computer screen onto a pen tablet, while we recorded their handwriting with high spatiotemporal resolution. Words involved a syllable-congruent visual disruption (e.g., “Gol fer ”), a morpheme-congruent visual disruption (e.g., “Golf er ”), or had no disruption (e.g., “Golfer”). We analyzed productions in terms of Writing Onset Duration and Letter Duration at the onset of the second syllable (“f” in “Gol.fer”) and the onset of the suffix (“e” in “Golf_er”). Results showed that durations were longer at word-writing onset only for words with a morpheme-congruent visual disruption. Also, letter durations were longer at the onset of the second syllable (i.e., “-fer”) and shorter at the onset of the suffix (i.e., “-er”) only for words with a syllable-congruent visual disruption. We interpret these findings within extant theories of handwriting production and offer an explanation for the observed effects before and during trajectory formation.

Abstract: Research on morphological processing has been mainly conducted in the single-word reading domain using the lexical-decision task. Similar research in the sentence reading domain has been conducted using eye-tracking techniques, yet the experimental paradigms used in each domain are not directly comparable. In the present study, we investigated morphological processing in single-word reading using the masked priming paradigm (Experiments 1a, 1b, 3), and in sentence reading using the fast priming paradigm in eye tracking (Experiment 2). The study was conducted in German using the same prefixed and suffixed items in both tasks. All experiments yielded an identical pattern of results, indicating early processing of the embedded stems, independently of whether these stems were combined with a prefix, a suffix, or a nonmorphological letter sequence. We interpret our findings in relation to previous results in the literature and discuss their implications for reading research both in the single-word and sentence-reading domains.

Abstract: Indicators of letter visual similarity have been used for controlling the design of empirical and neuropsychological studies and for rigorously determining the factors that underlie reading ability and literacy acquisition. Additionally, these letter similarity/confusability matrices have been useful for studies examining more general aspects of human cognition, such as perception. Despite many letter visual-similarity matrices being available, they all have two serious limitations if they are to be used by researchers in the reading domain: (1) They have been constructed using atypical reading data obtained from speeded reading-aloud tasks and/or under degraded presentation conditions (2) they only include letters from the English alphabet. Although some letter visual-similarity matrices have been constructed using data gathered from normal reading conditions, these either are based on old fonts, which may not resemble the letters found in modern print, or were never published. For the first time, this article presents a comprehensive letter visual-similarity/confusability matrix that has been constructed based on untimed responses to clearly presented upper- and lowercase letters that are present in many languages that use Latin-based alphabets, including Catalan, Dutch, English, French, Galician, German, Italian, Portuguese, and Spanish. Such a matrix will be useful for researchers interested in the processes underpinning reading and literacy acquisition.

Abstract: Two main theories of visual word recognition have been developed regarding the way orthographic units in printed words map onto phonological units in spoken words. One theory suggests that a string of single letters or letter clusters corresponds to a string of phonemes (Coltheart, 1978 Venezky, 1970), while the other suggests that a string of single letters or letter clusters corresponds to coarser phonological units, for ex le, onsets and rimes (Treiman & Chafetz, 1987). These theoretical assumptions were critical for the development of coding schemes in prominent computational models of word recognition and reading aloud. In a reading-aloud study, we tested whether the human reading system represents the orthographic honological onset of printed words and nonwords as single units or as separate letters honemes. Our results, which favored a letter and not an onset-coding scheme, were successfully simulated by the dual-route cascaded (DRC) model (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001). A separate experiment was carried out to further adjudicate between 2 versions of the DRC model.

Abstract: Syllables are thought to be processing units in handwritten word production. Yet, little is known about whether the orthographic characteristics of different languages influence syllabic processing during handwriting, which is critical for the evaluation and further development of extant models of handwritten language production. In the present study, we manipulated syllabic ambiguity, a characteristic of the German language, to investigate the role of syllables in handwritten word production in German. Forty-four 10 to 12-year-old children and fourteen adults were asked to write on pen tablets five-letter disyllabic words that varied in terms of their syllabic ambiguity, while their handwriting was recorded with high spatiotemporal resolution. Productions were analyzed in terms of Mean Stroke Duration (MSD) and Writing Onset Duration (WOD). Increased MSD at syllable boundaries was observed across conditions for both children and adults. There was no difference in WOD across conditions. Our findings offer support for the idea that syllables are functional units in handwriting production in German and motivate the further development of the spelling module in models of handwritten language production.

Abstract: The present study investigated whether morphological processing in reading is influenced by the orthographic consistency of a language or its morphological complexity. Developing readers in Grade 3 and skilled adult readers participated in a reading aloud task in four alphabetic orthographies (English, French, German, Italian), which differ in terms of both orthographic consistency and morphological complexity. English is the least consistent, in terms of its spelling‐to‐sound relationships, as well as the most morphologically sparse, compared to the other three. Two opposing hypotheses were formulated. If orthographic consistency modulated the use of morphology in reading, readers of English should show more robust morphological processing than readers of the other three languages, because morphological units increase the reliability of spelling‐to‐sound mappings in the English language. In contrast, if the use of morphology in reading depended on the morphological complexity of a language, readers of French, German, and Italian should process morphological units in printed letter strings more efficiently than readers of English. Both developing and skilled readers of English showed greater morphological processing than readers of the other three languages. These results support the idea that the orthographic consistency of a language, rather than its morphological complexity, influences the extent to which morphology is used during reading. We explain our findings within the remit of extant theories of reading acquisition and outline their theoretical and educational implications.

Abstract: A masked nonword prime generated by transposing adjacent inner letters in a word (e.g., jugde) facilitates the recognition of the target word (JUDGE) more than a prime in which the relevant letters are replaced by different letters (e.g., junpe). This transposed-letter (TL) priming effect has been widely interpreted as evidence that the coding of letter position is flexible, rather than precise. Although the TL priming effect has been extensively investigated in the domain of visual word recognition using the lexical decision task, very few studies have investigated this empirical phenomenon in reading aloud. In the present study, we investigated TL priming effects in reading aloud words and nonwords and found that these effects are of equal magnitude for the two types of items. We take this result as support for the view that the TL priming effect arises from noisy perception of letter order within the prime prior to the mapping of orthography to phonology.

Abstract: In this study, we investigated the effects of double-letter processing on handwriting production in beginning and skilled writers of German. One hundred and thirty-seven children from Grades 2 and 3 and 31 adult participants were asked to copy words with double consonants (e.g., “Kanne”) and matched words without double consonants (e.g., “Kante”) from a computer screen onto a pen tablet, while their handwriting was recorded with high spatio-temporal resolution. Handwriting productions were analysed in terms of Reading Duration, Writing Onset Duration, and Letter Duration at the letter positions preceding or forming the onset of the corresponding consonant clusters. Our results showed that second graders take less time to initiate writing words with double consonants than words without double consonants, while both second and third graders take less time to read words with double consonants than words without double consonants. Critically, although second and third graders write down a letter faster when it corresponds to the first letter of a double-letter unit than a consonant cluster, it is the other way around for adults. We interpret these findings within extant theories of handwriting production and offer an explanation for the different nature of the effects observed in beginning and skilled writers.

Abstract: Reading aloud is faster when target words/nonwords are preceded by masked prime words/nonwords that share their first sound with the target (e.g., s ave-SINK) compared to when primes and targets are unrelated to each other (e.g., farm-SINK). This empirical phenomenon is the masked onset priming effect (MOPE) and is known to be due to serial left-to-right processing of the prime by a sublexical reading mechanism. However, the literature in this domain lacks a critical experiment. It is possible that when primes are real words their orthographic honological representations are activated in parallel and holistically during prime presentation, so any phoneme overlap between primes and targets (and not just initial-phoneme overlap) could facilitate target reading aloud. This is the prediction made by the only computational models of reading aloud that are able to simulate the MOPE, namely the DRC1.2.1, CDP+, and CDP++ models. We tested this prediction in the present study and found that initial-phoneme overlap ( b lip-BEST), but not end-phoneme overlap ( flat-BEST), facilitated target reading aloud compared to no phoneme overlap ( junk-BEST). These results provide support for a reading mechanism that operates serially and from left to right, yet are inconsistent with all existing computational models of single-word reading aloud.

Abstract: The masked onset priming effect (MOPE) refers to the empirical finding that target naming is faster when the target (SIB) is preceded by a briefly presented masked prime that starts with the same letter honeme ( suf) than when it does not ( mof Kinoshita, 2000, Experiment 1). The dual-route cascaded (DRC) computational model of reading (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001) has offered an explanation for how the MOPE might occur in humans. However, there has been some empirical discrepancy regarding whether for nonword items the effect is limited to the first-letter honeme overlap between primes and targets or whether orthographic honological priming effects occur beyond the first letter honeme. Experiment 1 tested these two possibilities. The human results, which were successfully simulated by the DRC model, showed priming beyond the first letter honeme. Nevertheless, two recent versions of the DRC model made different predictions regarding the nature of these priming effects. Experiment 2 examined whether it is facilitatory, inhibitory, or both, in order to adjudicate between the two versions of the model. The human results showed that primes exert both facilitatory and inhibitory effects.
