Background: The role of morphological awareness for literacy development is non-controversial, but it is likely to depend on the characteristics of a specific orthography. Previous studies analysing the role of morphological awareness are mainly based on English samples; thus, it is unclear how generalisable these results are. In the current study, we evaluated the predictive pattern of morphological awareness on reading and spelling in German, which is characterised by high consistency between morphology and orthography. While many words cannot be spelled correctly by relying on phoneme-grapheme mappings, morphological awareness can be reliably used to infer the correct spelling for many words. In contrast, morphological awareness seems less important for reading in German given the high consistency of grapheme-phoneme mappings. Therefore, we hypothesised that the predictive pattern of morphological awareness for spelling is higher than for reading due to the structure of German orthography. In addition, we examined whether the association between morphological awareness and spelling reflects specific awareness about morphemic units or rather general knowledge about frequent and permissible letter sequences in words. Method: We developed web-based tasks that allowed us to assess morphological awareness using pseudowords. Based on the data of 3,122 third and fourth graders, we analysed the predictive pattern of morphological awareness on reading and spelling after controlling for non-verbal cognitive abilities, age/grade, phoneme awareness and sublexical orthographic sensitivity. Results: We found that morphological awareness accounted for significant amounts of unique variance over and above sublexical orthographic sensitivity in both literacy measures but was a better predictor for spelling than for reading. Conclusions: The role of morphological awareness depends on the structure of a given orthography. In German, this is reflected by differences in the predictive pattern between reading and spelling skills. Furthermore, results support the specific role of morphological awareness for spelling in the German orthography.

Purpose: The present study examined cross-linguistic differences in orthographic transparency and morphological complexity during complex word recognition in English and Italian. If morphological processing is more important in orthographically transparent and morphemically rich languages, larger morpheme-effects should be evident in Italian. However, if morphological processing is more pronounced in orthographically opaque and morphemically sparser languages, morpheme-effects should be larger in English. Method: 60 Italian (Mage = 25.33, 34 females, Caucasian) and 60 English (Mage = 26.35, 34 females, mostly Caucasian) native-speakers completed an online lexical decision task, while reaction times and accuracy were measured. To tease apart the independent role of stems and suffixes, we employed four types of nonwords: Stem+Suffix: night+ness, Stem+NonSuffix: night-lude, NonStem+Suffix: nisht+ness, NonStem+NonSuffix: nisht-lude). Results: The results revealed a significant morpheme interference effect in both languages: nonwords with stems were read slower and less accurately than those without stems and nonwords with suffixes slower and less accurately than those without suffixes. Crucially, this observed pattern was larger in English than Italian. Also, a significant Stem by Suffix interaction suggested that Stem+Suffix nonwords were harder to reject than all others. Conclusion: The current findings suggest that morphological processing is more pronounced in opaque orthographies like English, possibly because the activation of morphemic chunks can be used to compensate for grapheme-to-phoneme inconsistencies.

German skilled readers have been found to engage in morphological and syllable-based processing in visual word recognition. However, the relative reliance on syllables and morphemes in reading multi-syllabic complex words is still unresolved. This study aimed to unveil which of these sublexical units are the preferred units of reading by employing eye-tracking technology. Participants silently read sentences while their eye-movements were recorded. Words were visually marked using colour alternation (Experiment 1) or hyphenation (Experiment 2)—at syllable boundary (e.g., Kir-schen), at morpheme boundary (e.g., Kirsch-en), or within the units themselves (e.g., Ki-rschen). A control condition without disruptions was used as a baseline (e.g., Kirschen). The results of Experiment 1 showed that eye-movements were not modulated by colour alternations. The results of Experiment 2 indicated that hyphens disrupting syllables had a larger inhibitory effect on reading times than hyphens disrupting morphemes, suggesting that eye-movements in German skilled readers are more influenced by syllabic than morphological structure.

In this work we propose the use of Entropy to measure variability in pronunciations in pseudowords reading aloud: pseudowords where participants give many different pronunciations receive higher Entropy values. Monolingual adults, monolingual children, and bilingual children proficient in different European languages varying in orthographic depth were tested. We predicted that Entropy values will increase with increasing orthographic depth. Moreover, higher Entropy was expected for younger than older children, as reading experience improves the knowledge of grapheme-phoneme correspondences (GPCs). We also tested if interference from a second language would lead to higher Entropy. Results show that orthographic depth affects Entropy, but only when the items are not strictly matched across languages. We also found that Entropy decreases across age, suggesting that GPC knowledge becomes refined throughout grades 2-4. We found no differences between bilingual and monolingual children. Our results indicate that item characteristics play a fundamental role in pseudoword pronunciation variability, that reading experience is associated with reduced variability in responses, and that in bilinguals' knowledge of a second orthography does not seem to interfere with pseudoword reading aloud.

Artificial Orthography Learning (AOL) may act as a possible candidate to model the learning of print-to-speech correspondences. In order to serve as an adequate task, however, we need to establish whether AOL can be reliably measured. In the current study, we report the correlations between the learning of two different artificial orthographies by the same 55 participants. We also explore the correlation between AOL skill and other participant-level variables, namely Paired Associate Learning (PAL) performance, word and nonword reading ability, and age. We find high correlations between learning of two different artificial orthographies. Correlations with reading fluency and PAL are low. These results leave questions about the link between reading acquisition and AOL. At the same time, they show that AOL ability can be reliably measured and justify its use for future studies.
