What exactly is a yait anyway: The role of semantics in orthographic learning

This study investigated whether semantic information presented along with novel printed nonwords facilitates orthographic learning and examined predictors of individual differences in this important literacy skill. A sample of 35 fourth graders was tested on a variety of language and literacy tests, and participants were then exposed to 10 target nonwords, 5 of which were presented with semantic information. Children were tested 1 and 4 days later on their ability to correctly recognize and spell the target nonwords. Results revealed a significant main effect on the recognition task, where items presented with semantic information were identified correctly more often than were words presented in isolation. No significant effect of training condition was found for the spelling posttests. Furthermore, multiple regression analyses revealed that both phonological and semantic factors were significant predictors of orthographic learning. The findings support the view that orthographic learning, as measured through visual recognition, involves the integration of phonological, orthographic, and semantic representations.     

The role of linguistic and visual information in spelling: a developmental study

This study investigated the processes that elementary school children use for spelling. Good and poor spellers in grades 3 through 6 spelled words and nonwords that differed in the types of information (phonological, orthographic, morphological, or visual) that could be used to produce their correct spelling. A multiple choice spelling recognition task was also administered. Error rates on words and nonwords were related to the type of information that could be used to determine the correct spelling. Words that could be spelled on the basis of linguistic information were easier than words that could be spelled only on the basis of visual information. While children were sensitive to the linguistic properties of the stimuli, their use and knowledge of various sources of linguistic information was not uniformly developed. Children had the most difficulty with spellings based on morphological information and the least difficulty with those based on invariant sound-spelling relationships. On the dictation and the nonword tasks, younger children and poorer spellers differed from older children and better spellers in the overall level of their knowledge, but all children showed a similar pattern of results suggesting that they did not use different processes to spell words. However, the data from the recognition task suggested that poor spellers may rely more on visual information than good spellers.     

Strategy development and learning to spell new words: generalization of a process

The authors used microgenetic methods in 2 experiments to examine children's and adults' progress from initial attempts at spelling nonwords to later direct memory retrieval of the spellings. Participants repeatedly spelled nonwords presented in computerized, dictated-word spelling tests over several weeks. Following each spelling, participants provided retrospective strategy reports. Half of the children showed a gradual shift from spelling words with effortful backup strategies to fast retrieval; half of the children continued using backup strategies that were fast and effective for them. Relatively more adults shifted from backup strategies to retrieval, but otherwise their patterns of spelling development were quite similar to those of the children. This research provides support for the generalizability of the overlapping waves model to nonalgorithmic domains. It also demonstrates parallels between children and adults in learning to spell new words.     

Linguistic semantic agraphia: A dissociation of the lexical spelling system from semantics

Two spelling systems have been described. The phonological system transcodes speech sounds to letters and is thought to be useful for spelling regular words and pronounceable nonwords. Although the second system, the lexical-semantic system, is thought to use visual word images and meaning to spell irregular words, it is not known if this system is dependent on semantic knowledge. We used a homophone spelling test to examine the lexical-semantic system in five patients. The patients were asked to spell individual homophones (doe or dough) using the context of a sentence. Semantically incorrect and correct homophones were spelled equally well, whether they were regular or irregular. These results demonstrate that an irregular word may be spelled without knowledge of the word's meaning. Therefore, the lexical system can be dissociated from semantic influence.     

Construction and learning to spell

Little is known about the way in which children learn the rules of literacy. We argue that children’s learning about orthographic rules can be the result of their own constructions. We provide longitudinal evidence on Greek children’s understanding of the morphophonemic rules for the spelling of the /o/ and /e/ vowel sounds in stems and inflections. These sounds can be spelled with more than one phonetically acceptable grapheme. When the vowel sound represents part of an inflection or the inflection itself, the grammatical status of the word is the key to the right choice between the alternative spellings. In contrast, no such morphemic rule applies when the sound is part of the stem morpheme. The spelling of each of these vowel sounds in the stem must rely on rote learning. Our results suggest that children go through a three-step developmental sequence in learning how to spell /o/ and /e/ in inflections: initially they adopt only one spelling for each vowel sound. Later, when they add the alternative spelling to their repertoire, they overgeneralize it to inappropriate words. Eventually, they restrict the alternative spellings to the grammatically appropriate words. We argue that these overgeneralizations, which have also been found in English, French and Portuguese spelling, indicate that children at first try to extend an existing rule, based on grapheme–phoneme conversion, for the new spelling. This slight change produces new experiences for them which allow them to construct a higher-level morphophonemic spelling rule.     

Phonological and semantic information in adults' orthographic learning

A training paradigm was used to assess the early stages of the acquisition of novel letter strings in adults. Provision of either phonological or semantic information during training improved spelling recognition (Experiment 1). Manipulation of the processing required during training (phonological, semantic, or both) produced no consistent effects on spelling when both phonology and meaning were provided (Experiment 2). An advantage of phonological over orthographic processing on spelling recognition and cued recall was found when meaning was provided during training but phonology was not (Experiment 3). The experiments support the role of phonological information in early learning of orthography, but additional research is required to clarify when and how semantic information supports the formation of new orthographic representations.     

Orthographic learning in children with isolated and combined reading and spelling deficits

Dissociations between reading and spelling problems are likely to be associated with different underlying cognitive deficits, and with different deficits in orthographic learning. In order to understand these differences, the current study examined orthographic learning using a printed-word learning paradigm. Children (4th grade) with isolated reading, isolated spelling and combined reading and spelling problems were compared to children with age appropriate reading and spelling skills on their performance during learning novel words and symbols (non-verbal control condition), and during immediate and delayed reading and spelling recall tasks. No group differences occurred in the non-verbal control condition. In the verbal condition, initial learning was intact in all groups, but differences occurred during recall tasks. Children with reading fluency deficits showed slower reading times, while children with spelling deficits were less accurate, both in reading and spelling recall. Children with isolated spelling problems showed no difficulties in immediate spelling recall, but had problems in remembering the spellings 2 hours later. The results suggest that different orthographic learning deficits underlie reading fluency and spelling problems: Children with isolated reading fluency deficits have no difficulties in building-up orthographic representations, but access to these representations is slowed down while children with isolated spelling deficits have problems in storing precise orthographic representations in long-term memory.     

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.     

The Effects of Partner Learning During Spelling for Students with Severe Disabilities and Their Peers

A multiple baseline across subjects design was used to examine the effects of partner learning on the spelling performance, academic responding, and competing behavior of three students with severe disabilities and three of their classmates without disabilities. The students were enrolled in different general elementary classes. All students in these classes were assigned to partner learning triads by the general education teacher. One triad in each class included the student with severe disabilities and two classmates without disabilities. All students in the class received two, 20 min partner learning sessions each week. During partner learning, each member of the triad was asked to spell words, present words to be spelled, provide feedback to the speller, and check the spelling accuracy. These roles were rotated among the members of the triad after each trial. These roles were adapted as necessary to accommodate the academic and communication skills of the students with severe disabilities. The effects of partner learning on spelling accuracy were assessed through weekly spelling tests. The effects of partner learning on academic responding and competing behavior were assessed using the MS-CISSAR (Carta, Greenwood, Schulte, Arreaga-Mayer, Terry, 1988). Results of weekly spelling indicated that partner learning led to improved spelling accuracy for students with severe disabilities and did not negatively affect the spelling accuracy of their peers. Partner learning also led to improved rates of academic responding and reduced rates of competing behavior for 5 of 6 students. The results are discussed in terms of their implications for practice and future research.     

Spelling dyslexia: A form of cross-cuing

A patient with spelling dyslexia maintained the ability to write, spell, and pronounce spelled nonsense words and words that require knowledge of orthographic rules of language. He was unable to perform grapheme-phoneme conversions except after naming the letter involved. We propose that he uses a letter-naming strategy to circumvent the disconnection of visual areas from the area of visual word images and that his letter-naming strategy represents a compensatory cross-cuing strategy.     

Visual memory in a spelling matching task: comparison of good and poor spellers

The role of visual memory in learning to spell words was investigated through a matching task on which one nonsense word was presented, then a second word identical in spelling or differing in one letter was presented. Ten pairs of 9th and 10th-grade students, matched for intelligence and sex but of different spelling ability, were asked to indicate whether word pairs were spelled the same or differently. The two words of a pair were either the same or different in print size or letter case. Significant effects were obtained for spelling ability, print size (same or different), and letter case (same or different), and the interaction of size X case, providing evidence for the use of visual memory by both good and poor spellers in learning to spell words. Good spellers were equally able to identify matched and mismatched pairs, while poor spellers showed greater difficulty in identifying mismatches than matches, supporting Frith's (1980) "partial cues" explanation of poor spelling performance.     

Orthographic influences in spoken word recognition: The consistency effect in semantic and gender categorization tasks

According to current models, spoken word recognition is driven by the phonological properties of the speech signal. However, several studies have suggested that orthographic information also influences recognition in adult listeners. In particular, it has been repeatedly shown that, in the lexical decision task, words that include rimes with inconsistent spellings (e.g., /-ip/ spelled -eap or -eep) are disadvantaged, as compared with words with consistent rime spelling. In the present study, we explored whether the orthographic consistency effect extends to tasks requiring people to process words beyond simple lexical access. Two different tasks were used: semantic and gender categorization. Both tasks produced reliable consistency effects. The data are discussed as suggesting that orthographic codes are activated during word recognition, or that the organization of phonological representations of words is affected by orthography during literacy acquisition.     

Context effects on orthographic learning of regular and irregular words

The self-teaching hypothesis proposes that orthographic learning takes place via phonological decoding in meaningful texts, that is, in context. Context is proposed to be important in learning to read, especially when decoding is only partial. However, little research has directly explored this hypothesis. The current study looked at the effect of context on orthographic learning and examined whether there were different effects for novel words given regular and irregular pronunciations. Two experiments were conducted using regular and irregular novel words, respectively. Second-grade children were asked to learn eight novel words either in stories or in a list of words. The results revealed no significant effect of context for the regular items. However, in an orthographic decision task, there was a facilitatory effect of context on irregular novel word learning. The findings support the view that contextual information is important to orthographic learning, but only when the words to be learned contain irregular spelling-sound correspondences.     

The role of phonological recoding in orthographic learning

The objective of this research was to explore whether orthographic learning occurs as a result of phonological recoding, as expected from the self-teaching hypothesis. The participants were 32 fourth- and fifth-graders (mean age = 10 years 0 months, SD = 7 months) who performed lexical decisions for monosyllabic real words and pseudowords under two matched experimental conditions: a read aloud condition, wherein items were named prior to lexical decision to promote phonological recoding, and a concurrent articulation condition, presumed to attenuate phonological recoding. Later, orthographic learning of the pseudowords was evaluated using orthographic choice, spelling, and naming tasks. Consistent with the self-teaching hypothesis, targets learned with phonological recoding in the read aloud condition yielded greater orthographic learning than those learned with concurrent articulation. The research confirms the critical nature of phonological recoding in the development of visual word recognition skills and an orthographic lexicon.     

Using morphology when spelling in a shallow orthographic system: The case of Spanish

Deep orthographies usually represent morphology and phonology simultaneously; both resources are necessary for spelling. In shallow orthographies, such as Spanish, phonology would be enough to spell most words. However, morphological knowledge may also take part in spelling. This study examined how Spanish children in 1st (N = 148), 2nd (N = 155) and 3rd grade (N = 155) use morphological information to spell plural nouns and verbs. A word dictation task was designed. The task included high and low frequency plural nouns ending in “s” (morphological “-s” condition) and verbs in the 2nd person ending in “s” (morphological “-s” condition). A lexical condition including words with a final “s” which was not morphologically motivated was used as a control condition (lexical “-s” condition). The results show that, although Spanish spelling is influenced by phonology, morphological information is also used. These results are discussed in relation to current models of word spelling.     

Morphological effects in children's spelling of French words.

The present study examined whether primary school children represent morphological information when spelling French words that have silent-consonant endings (e.g., chat). Children in grades 2 (n = 57) and 4 (n = 55) spelled regular, morphological, and deep words. The morphological and deep words differed in the presence or absence of derivatives that revealed the nature of the silent-consonant ending. As expected, regular words were the easiest to spell whereas morphological words (for which the silent consonant could be derived) were easier to spell than were deep words (for which the silent consonant must be memorized). Children's linguistic knowledge of morphology made a contribution to their spelling of morphological words that was independent of reading experience, vocabulary, spelling ability (i.e., spelling regular words), and phoneme awareness.     

The influence of consistency, frequency, and semantics on learning to read: an artificial orthography paradigm

Two experiments explored learning, generalization, and the influence of semantics on orthographic processing in an artificial language. In Experiment 1, 16 adults learned to read 36 novel words written in novel characters. Posttraining, participants discriminated trained from untrained items and generalized to novel items, demonstrating extraction of individual character sounds. Frequency and consistency effects in learning and generalization showed that participants were sensitive to the statistics of their learning environment. In Experiment 2, 32 participants were preexposed to the sounds of all items (lexical phonology) and to novel definitions for half of these items (semantics). Preexposure to either lexical phonology or semantics boosted the early stages of orthographic learning relative to Experiment 1. By the end of training, facilitation was restricted to the semantic condition and to items containing low-frequency inconsistent vowels. Preexposure reduced generalization, suggesting that enhanced item-specific learning was achieved at the expense of character-sound abstraction. The authors' novel paradigm provides a new tool to explore orthographic learning. Although the present findings support the idea that semantic knowledge supports word reading processes, they also suggest that item-specific phonological knowledge is important in the early stages of learning to read.     

Distinguishing representation deficits and processing deficits in a case of acquired dysgraphia

The same acquired disorder of spelling may be due to deficits affecting lexical representations of word spelling or deficits affecting the mechanisms that process those representations. This study sought to distinguish these possibilities in a dysgraphic patient. The integrity of the patient's lexical orthographic representations was assessed by having him decide whether or not pairs of words presented auditorily rhymed. Although the patient was impaired on a variety of spelling tasks and with all types of stimulus material, he showed a normal effect of spelling on the rhyme task. Like normal subjects, he was faster at deciding that words rhymed when they were spelled similarly (e.g. tool-cool) than when they were spelled dissimilarly (e.g. rule-cool) and slower at deciding that words did not rhyme when they were spelled similarly (e.g. toad-broad) than when they were spelled dissimilarly (e.g. code-broad). Therefore, as the patient's lexical representations of word spelling seemed to be generally intact, his spelling problems were probably due to difficulty in processing those representations.
