Morphological knowledge as revealed in children's spelling accuracy and reports of spelling strategies

The goal of the current research was to assess whether children can make strategic use of morphological relations among words to spell. French-speaking children in Grade 4 spelled three word types: (a) phonological words that had regular phoneme-grapheme correspondences, (b) morphological words that had silent consonant endings for which a derivative revealed the silent ending, and (c) lexical words that had silent consonant endings for which no familiar derivative revealed the ending. Children were also asked to provide immediate retrospective reports of the strategies used to spell each word. Two experiments (Ns = 46 and 39) were conducted. As expected, children in Grade 4 spelled phonological words more accurately than they did words with silent consonant endings. In addition, children spelled morphological words more accurately than they did lexical words. Reports of using retrieval were associated with accurate performance across word types. Importantly, reports of using morphological strategies to spell morphological words were associated with a similar level of accuracy, as were reports of using retrieval. Even though children reported using a phonological strategy frequently across all word types, this strategy was associated with accurate performance only for spelling phonological words. Experiment 2 replicated the results of Experiment 1 with another set of stimuli and also showed that children's morphological awareness predicted their spelling accuracy for morphological words as well as the reported frequency of morphological strategy use. In sum, the findings revealed that most children showed evidence of adaptive strategy use.     

The effects of word class on children's reading and spelling

Children's oral language functioning has been shown to be affected by word class (i.e., content vs. noncontent words). The present study reveals comparable effects on children's written language performance. In spelling and reading, third and fifth graders show faster and more accurate responses to nouns and verbs than to noncontent words of matched length and frequency. Further, when the children's performance is examined in relation to level of reading skill, it is found that the less-skilled readers exhibit a greater content/noncontent differential than do the more skilled readers. The results are discussed with reference to differential access for the two word classes and its implication for both oral and written language functioning.     

The effects of training of morphological structure on spelling derived words by dyslexic adolescents

This exploratory study aimed to determine the effects of explicit instruction about morphological structure on the spelling of derived words. A cross‐sectional ability level‐design was employed in order to determine differences in response to instruction between dyslexic students aged 13+years and age‐matched and spelling level matched control groups. The study was based on the word‐pair paradigm (a base and derived word) and combined oral instruction with written materials. The intervention had a substantial impact in enhancing the spelling of derivations by the dyslexic adolescents. Their gains were appropriate for their spelling level, stable two months after the intervention, and generalized to untrained but analogous items in terms of structure and suffixation. Non‐dyslexic younger participants matched in terms of spelling level also showed training and generalisation effects of the same size as their dyslexic counterparts, while the age‐matched controls did not improve so much because of ceiling effects. It is proposed that morphological awareness constitutes a positive asset for dyslexic adolescents that can be used efficiently to counterbalance their severe phonological deficiencies.     

Syllables and spelling units affect feature integration in words

Three experiments showed that syllables and spelling patterns function as higher order units in word perception. Subjects were required to identify the color of a target letter in briefly presented words composed of different-colored letters. In Experiment 1, subjects incorrectly reported the color of a nontarget letter (conjunction error) more often in one-syllable words containing few spelling units than in two-syllable words containing many spelling units. Experiment 2 showed that subjects made more conjunction errors in one-syllable words than in two-syllable words when the number of spelling patterns was controlled. Experiment 3 showed that conjunction errors decreased as spelling units increased when the number of syllables was held constant. Experiments 1 and 3 also showed that more conjunction errors occurred within syllabic and spelling units than between these units. These findings are discussed in light of previous research on syllable and spelling pattern effects.     

Deaf and hearing children's plural noun spelling

The present study examines deaf and hearing children's spelling of plural nouns. Severe literacy impairments are well documented in the deaf, which are believed to be a consequence of phonological awareness limitations. Fifty deaf (mean chronological age 13;10 years, mean reading age 7;5 years) and 50 reading-age-matched hearing children produced spellings of regular, semiregular, and irregular plural nouns in Experiment 1 and nonword plurals in Experiment 2. Deaf children performed reading-age appropriately on rule-based (regular and semiregular) plurals but were significantly less accurate at spelling irregular plurals. Spelling of plural nonwords and spelling error analyses revealed clear evidence for use of morphology. Deaf children used morphological generalization to a greater degree than their reading-age-matched hearing counterparts. Also, hearing children combined use of phonology and morphology to guide spelling, whereas deaf children appeared to use morphology without phonological mediation. Therefore, use of morphology in spelling can be independent of phonology and is available to the deaf despite limited experience with spoken language. Indeed, deaf children appear to be learning about morphology from the orthography. Education on more complex morphological generalization and exceptions may be highly beneficial not only for the deaf but also for other populations with phonological awareness limitations.     

Learning a novel grapheme: effects of positional and phonemic context on children's spelling

Two experiments explored how children who encounter a new spelling for a phoneme generalize it to novel items. Children ages 5 1/2 to 9 (N = 123) were taught a CVC (consonant-vowel-consonant) nonword containing a new vowel spelling in the middle position (e.g., /gaik/ is spelled as giik). They were then asked to spell other nonwords containing the vowel or to judge spellings that had supposedly been produced by younger children. Children were sensitive to position in the spelling production task, being more likely to use the novel grapheme when the vowel appeared in the middle of a CVC target than when it appeared in word-initial or word-final position. Children were not significantly more likely to use the novel grapheme when the target shared the vowel and final consonant (rime) of the training stimulus than when it shared the initial consonant and vowel. Implications for views of spelling development are discussed.     

Memory for words as a function of spelling transparency

The authors investigated the impact of spelling transparency on memory for words written in Persian orthography. Adult Persian university students (N = 212) performed in a memory recall experiment on 160 monosyllabic words printed on 8 cards (20 on each card) manipulated for spelling transparency, frequency, and imageability. Each card was presented randomly to the participants and they were asked to read the words aloud as quickly as possible. After reading each card, the participants were asked to engage in a digital addition task for 20 s (as a distracter), which was immediately followed by a request to write down as many words as possible from the cards in 40 s. No significant difference was found in the time to name aloud the opaque and transparent words, whereas on the memory recall task there were main effects for spelling, frequency, and imageability and significant 2-way and 3-way interactions. The effects were greatest for transparent spellings when they were of high frequency and high imageability or low frequency and low imageability. The implications of these findings are discussed.     

The timing and mechanisms of children's use of morphological information in spelling: A review of evidence from English and French

We present a review of the research on English and French children's learning of the place of morphemes in spelling. Traditional models suggest that children use morphology relatively late in their spelling careers and that the end-point of development lies in rule-based performance. In contrast, we show that (a) children are sensitive to the role of morphemes in determining spelling at a young age and (b) they do not rely (at least exclusively) on rules. We discuss the features that may account for discrepancies between studies demonstrating late versus early use of morphology and we examine the processes that children might rely on in their learning, specifically statistical learning of intra- and inter-word regularities and retrieval of item-specific representations. This proposal provides a potential explanation for how children learn about the representation of morphology in print.     

Reading, spelling, and recognition of briefly exposed words and nonwords.

Four groups distinct in terms of English reading comprehension and spelling skills were identified among 141 Japanese college students: 5 good readers and spellers, 6 good readers but poor spellers, 3 poor readers but good spellers, and 4 poor readers and poor spellers. They were then tested on instantaneous recognition of words and nonwords. Analysis showed that the recognition performance was more strongly associated with spelling than with reading comprehension. Immediate memory and "sophisticated" guessing, which were associated with spelling, were considered to be critical for the recognition task, but the hypothesis that a common processing mechanism is involved in instantaneous word recognition and spelling was rejected.     

Effects of delayed constructed-response identity matching on spelling of dictated words

We studied the effects of delayed constructed-response identity matching on spelling with 6 first graders with histories of school failure. After training, the children learned to spell words to dictation and their cursive writing improved. These results replicate studies showing that delayed constructed-response matching establishes spelling. For 2 children, spelling of generalization words--words formed by recombining the syllables of training words--also improved. These results extend studies that have shown recombinative generalization in reading and spelling.     

Neighborhood effects in spelling in adults

The participants were asked to spell aloud words for which there were either many orthographically similar words (a dense neighborhood) or few orthographically similar words (a sparse neighborhood). Words with a dense neighborhood were spelled faster and more accurately than were words with a sparse neighborhood. This finding is consistent with the hypothesis of Rapp, Epstein, and Tainturier (2002), that the cognitive spelling system has an interactive architecture incorporating feedback between individual graphemes and orthographic lexeme representations.     

Statistical analysis of the bidirectional inconsistency of spelling and sound in French

Recent studies suggest that performance attendant on visual word perception is affected not only by the “traditional” feedforward inconsistency (spelling → phonology) but also by its feedback inconsistency (phonology → spelling). The present study presents a statistical analysis of the bidirectional inconsistency for all French monosyllabic words. We show that French is relatively consistent from spelling to phonology but highly inconsistent from phonology to spelling. Appendixes B and C list prior and conditional probabilities for all inconsistent mappings and thus provide a valuable tool for controlling, selecting, and constructing stimulus materials for psycholinguistic and neuropsychological research. Such large-scale statistical analyses about a language’s structure are crucial for developing metrics of inconsistency, generating hypotheses for cross-linguistic research, and building computational models of reading.     

Predicting children's word‐spelling difficulty for common English words from measures of orthographic transparency,phonemic and graphemic length and word frequency

Spencer demonstrated that spelling and reading difficulty for English words can be predicted from a number of factors, including word frequency, phonemic length and measures of orthographic depth and complexity. In this study, spelling difficulty of high frequency words was investigated across five year groups (ages 7 to 11 years) with a wide ranging series of data sources from which to determine word frequency values and orthographic depth measures. A regression model accounted for 52–66% of the variance for 7‐ to 11‐year‐olds and 72% of the variance for the lowest performing quartile group, irrespective of age. The most influential factor, phonetic difference (being the difference in the number of letters and phonemes in a word, and representing grapheme complexity), links the relative influence of large graphemic units in foundation literacy to a similar phenomenon, the ‘whammy’ effect, which provides support for serial processing in the dual route cascade model of word recognition in skilled readers ( Rastle & Coltheart, 1998 ). The study supports recent research on European orthographies, which concludes that both orthographic depth and complexity contribute to delayed acquisition of foundation literacy skills.     

Perceptual processing of partially and fully assimilated words in French

Models of speech perception attribute a different role to contextual information in the processing of assimilated speech. This study concerned perceptual processing of regressive voice assimilation in French. This phonological variation is asymmetric in that assimilation is partial for voiced stops and nearly complete for voiceless stops. Two auditory-visual cross-modal form priming experiments were used to examine perceptual compensation for assimilation in French words with voiceless versus voiced stop offsets. The results show that, for the former segments, assimilating context enhances underlying form recovery, whereas it does not for the latter. These results suggest that two sources of information -- contextual information and bottom-up information from the assimilated forms themselves -- are complementary and both come into play during the processing of fully or partially assimilated word forms.     

Sex differences in children's attributions for success and failure on math and spelling tests

Sex differences in children's attributions for success and failure were tested on a group of 165 fifth and sixth graders taking a regularly scheduled math and spelling test in their classroom. Pretest questionnaires measured students' self-perceptions of competence in the subject and their performance expectations on the test. Questionnaires, given after the corrected tests were returned, assessed students' actual performance, subjective ratings of success, attributions for the cause of their success or failure, and performance expectations for future tests. Results indicated that sex differences existed in math but not in spelling: compared to girls, boys perceived themselves to be more competent and did better on the math test. Boys were also less likely to attribute failure on the math test to lack of ability and more likely to attribute success to ability than were girls.     

Recognizing orally spelled words: an analysis of procedures shared with reading and spelling

Some investigators have suggested that recognizing orally spelled words is dependent on the same procedures ordinarily used in spelling, whereas others have viewed it either as dependent on reading procedures or as an independent ability. In the present study, a single subject with dyslexia and dysgraphia was examined on parallel tests of recognizing orally spelled words, reading, and spelling (writing), and a comparison was made of his performance on the three tasks. On both words and nonwords, the patient's errors in recognizing orally spelled words and in reading were alike, whereas his spelling errors were often different. The distinction between recognizing orally spelled words and spelling was further shown by his inability to recognize a set of orally spelled words that he could write correctly to dictation or on the basis of word meaning. These findings suggest that the procedures normally used for reading can accept sequences of letter identities as input when orally spelled words must be recognized.     

The metric matters: determining the extent of children's knowledge of morphological spelling regularities

All developmental research needs to carefully consider how children's knowledge is measured. The study of children's knowledge of spelling conventions, or the ways in which the English orthography encodes the roots and affixes and the sounds in words, is no exception. This experiment examined the extent of 7- to 9-year-old children's knowledge of the role of root morphemes in spelling words across different contexts and with different units of assessment. Different writing contexts did not appear to affect children's performance; children were better able to spell the first components of two- than of one-morpheme words (e.g. only free in freely and freeze), both when writing whole words and their first sections (e.g. completing__ or __ly for freely). A second analysis revealed that the unit of coding can influence conclusions. Children demonstrated similar abilities across ages 7 to 9 when only the first segments of words were coded; in contrast, there was evidence of age-related differences when whole word spelling accuracy was assessed. In combination, these results suggest that children's knowledge of the principle of root consistency is remarkably robust to changes in writing context, but that coding is key when drawing conclusions. These findings remind us that the metric matters in studies of spelling, as in other domains, and they offer a manner to reconcile previously conflicting data on spelling development.
