Understanding Language Attrition through Orthography

The decay in the proficiency of the native language (L1), known as first language attrition, is one of the least understood phenomena associated with the acquisition of a second language (L2). Indeed, the exact cause for the deterioration in L1 performance, be that either the interference from L2 acquisition or the less frequent use of L1, still remains elusive. In this opinion paper, we focus on one largely understudied aspect of L1 attrition—namely, the erosion of the L1 orthographic knowledge under the influence of L2 orthography. In particular, we propose to study differences in orthographic processing between mono- and bilingual populations as an approach, which, in turn, will allow to address both cognitive and neurophysiological mechanisms underlying L1 attrition. We discuss relevant experimental paradigms, variable manipulations and appropriate research methods that may help disentangle the largely debated question of L2 interference vs. L1 disuse, clarifying the nature of the L1 orthographic attrition.

EXPRESS: Consonant and vowel transpositions effects during reading development: a study on Italian children and adults

Recently, Colombo, Spinelli, and Lupker (2020), using a masked transposed letter (TL) priming paradigm, investigated whether consonant/vowel (CV) status is important early in orthographic processing. In four experiments with Italian and English adults, they found equivalent TL priming effects for CC, CV, and VC transpositions. Here, we investigated that question with younger readers (age 7 to 10) and adults, as well as whether masked TL priming effects might have a phonological basis. That is, because young children are likely to use phonological recoding in reading, the question was whether they would show TL priming that is affected by CV status. In Experiment 1, target words were preceded by primes in which two letters (either CV, VC, or CC) were transposed versus substituted (SL). We found significant TL priming effects, with an increasing developmental trend, but, again, no letter type by priming interaction. In Experiment 2 the transpositions/substitutions involved only pairs of vowels with those vowels having either diphthong or hiatus status. The difference between these vowel clusters is only phonological, thus the question was would TL priming interact with this factor. TL priming was again found with an increasing trend with age, but there was no vowel cluster by priming interaction. There was, however, an overall vowel cluster effect (slower responding to words with hiatuses) which decreased with age. The results suggest that TL priming only taps the orthographic level, and that CV status only becomes important at a later phonological level.

ERP Correlates of Altered Orthographic-Phonological Processing in Dyslexia

Automatic visual word recognition requires not only well-established phonological and orthographic representations but also efficient audio-visual integration of these representations. One possibility is that in developmental dyslexia, inefficient orthographic processing might underlie poor reading. Alternatively, reading deficit could be due to inefficient phonological processing or inefficient integration of orthographic and phonological information. In this event-related potential study, participants with dyslexia (N = 25) and control readers (N = 27) were presented with pairs of words and pseudowords in an implicit same-different task. The reference-target pairs could be identical, or different in the identity or the position of the letters. To test the orthographic-phonological processing, target stimuli were presented in visual-only and audiovisual conditions. Participants with and without dyslexia processed the reference stimuli similarly; however, group differences emerged in the processing of target stimuli, especially in the audiovisual condition where control readers showed greater N1 responses for words than for pseudowords, but readers with dyslexia did not show such difference. Moreover, after 300 ms lexicality effect exhibited a more focused frontal topographic distribution in readers with dyslexia. Our results suggest that in developmental dyslexia, phonological processing and audiovisual processing deficits are more pronounced than orthographic processing deficits.

Cross-linguistic differences in parafoveal semantic and orthographic processing

In this study we investigated parafoveal processing by L1 and late L2 speakers of English (L1 German) while reading in English. We hypothesized that L2ers would make use of semantic and orthographic information parafoveally. Using the gaze contingent boundary paradigm, we manipulated six parafoveal masks in a sentence (Mark found th*e wood for the fire; * indicates the invisible boundary): identical word mask (wood), English orthographic mask (wook), English string mask (zwwl), German mask (holz), German orthographic mask (holn), and German string mask (kxfs). We found an orthographic benefit for L1ers and L2ers when the mask was orthographically related to the target word (wood vs. wook) in line with previous L1 research. English L2ers did not derive a benefit (rather an interference) when a non-cognate translation mask from their L1 was used (wood vs. holz), but did derive a benefit from a German orthographic mask (wood vs. holn). While unexpected, it may be that L2ers incur a switching cost when the complete German word is presented parafoveally, and derive a benefit by keeping both lexicons active when a partial German word is presented parafoveally (narrowing down lexical candidates). To the authors’ knowledge there is no mention of parafoveal processing in any model of L2 processing/reading, and the current study provides the first evidence for a parafoveal non-cognate orthographic benefit (but only with partial orthographic overlap) in sentence reading for L2ers. We discuss how these findings fit into the framework of bilingual word recognition theories.

The Impact of Phonological and Orthographic Processing on Reading Speed in Russian-Speaking Children

Phonological and orthographic processing are reported to be among the strongest predictors of reading development across different Indo-European languages. The relative impact of these factors can be modulated by cross-linguistic script and orthographic differences, as evidenced by many studies in European languages. The present study investigates the effect of phonological and orthographic processing on reading speed in 6- to 12-year-old (1 – 5 grades) Russian-speaking children (N = 117), taking into account age as a factor as well. Phonological and orthographic processing were assessed with behavioral tests. The results revealed that both skills predict reading speed in Russian. Moreover, the age of young readers can also be a non-linguistic predictor of reading speed in Russian, especially in children between 6 and 10 years old. Children aged 10 to 12 also demonstrated some variability in reading speed, although an increase in reading speed was no longer observed.

On non-adjacent letter repetition and orthographic processing: Lexical decisions to nonwords created by repeating or inserting letters in words

Informal observation suggests that it is harder to notice the spelling mistake in “silencne” than “silencre.” This concurs with current evidence that non-adjacent letter repetition in correctly spelled words makes these words harder to recognize. One possible explanation is provided by open-bigram coding. Words containing repeated letters are harder to recognize because they are represented by fewer bigrams than words without repeated letters. Building on this particular explanation for letter-repetition effects in words, we predicted that nonwords in a lexical decision task should also be sensitive to letter repetitions. In particular, we examined two types of nonwords generated from the same baseword: (1) nonwords created by repeating one of the letters in the baseword (e.g., silence => silencne); and (2) nonwords created by inserting a letter that is not present in the baseword (e.g., silencre). According to open-bigram coding, nonwords created by repeating a letter are more similar to their baseword than nonwords created by inserting a letter, and this should make it harder to reject letter repetition nonwords than letter insertion nonwords. We put these predictions to test in one on-line pilot study (n=31), one laboratory experiment (n=36), and one follow-up on-line experiment (n=40) where we manipulated the distance between repetitions (one, two, three, or four letters). Participants found it harder to reject repetition nonwords than insertion nonwords, and this effect diminished with increasing distance.

Attention extends beyond single words in beginning readers

A common notion is that during the first stages of learning to read, attention is narrowly focused so as to encompass only a single or a few letters. In skilled adult readers, however, attention extends beyond single words. The latter is evidenced by faster recognition of words that have many letters in common with surrounding words, along with correlations between such integration effects and measures of attention. These premises suggest that the distribution of attention gradually increases as a function of reading skill, and that this progression can be mapped by measuring spatial integration effects across the course of reading development. The latter was undertaken in the present study, in which we employed the flanker paradigm combined with the lexical decision task. Children in grades 1―6 (N = 113) were shown central target words flanked by various types of orthographically related and unrelated flanking stimuli. Against expectations, significant effects of flanker relatedness on word recognition speed were found in the youngest children, and this effect was not modulated by reading age. Our results challenge the notion that attention is focused on single letters in beginning readers, and instead suggest that, from the earliest stages of reading development, orthographic processing can extend beyond single words.
