The efficacy of orthographic rime, grapheme-phoneme correspondence, and implicit phonics approaches to teaching decoding skills

This study compared the efficacy of two decoding skill-based programs, one based on explicit orthographic rime and one on grapheme–phoneme correspondences, to a control group exposed to an implicit phonics program. Children in both explicit decoding programs performed consistently better than the control group in the accuracy with which they read and spelled words covered in the program. Only children in the grapheme–phoneme correspondence program consistently spelled transfer words better than children in the control group. In addition, children in the grapheme–phoneme correspondence group consistently read words more quickly than children in the control group. Children in both explicit decoding programs scored higher than the children in the control group on measures of reading comprehension and oral reading at posttest

Is a "Phoenician" reading style superior to a "Chinese" reading style? Evidence from fourth graders

This study compared normally achieving fourth-grade "Phoenician" readers, who identify nonwords significantly more accurately than they do exception words, with "Chinese" readers, who show the reverse pattern. Phoenician readers scored lower than Chinese readers on word identification, exception word reading, orthographic choice, spelling, reading comprehension, and verbal ability. When compared with normally achieving children who read nonwords and exception words equally well, Chinese readers scored as well as these children on word identification, regular word reading, orthographic choice, spelling, reading comprehension, phonological sensitivity, and verbal ability and scored better on exception word reading. Chinese readers also used rhyme-based analogies to read nonwords derived from high-frequency exception words just as often as did these children. As predicted, Phoenician and Chinese readers adopted somewhat different strategies in reading ambiguous nonwords constructed by analogy to high-frequency exception words. Phoenician readers were more likely than Chinese readers to read ambiguous monosyllabic nonwords via context-free grapheme–honeme correspondences and were less likely to read disyllabic nonwords by analogy to high-frequency analogues. Although the Chinese reading style was more common than the Phoenician style in normally achieving fourth graders, there were similar numbers of poor readers with phonological dyslexia (identifying nonwords significantly more accurately than exception words) and surface dyslexia (showing the reverse pattern), although surface dyslexia was more common in the severely disabled readers. However, few of the poor readers showed pure patterns of phonological or surface dyslexia

Nonword repetition and young children's receptive vocabulary: A longitudinal study

A longitudinal study investigated the claim that phonological memory contributes to vocabulary acquisition in young children. In the first phase, children were given tests of receptive vocabulary, receptive grammar, nonword repetition, phonological sensitivity (or awareness), and performance IQ. In the second phase, children were given the nonword repetition and receptive vocabulary tests. In Session 1, both nonword repetition and phonological sensitivity accounted for variation in receptive vocabulary and grammar after performance IQ effects were controlled. When phonological sensitivity was also controlled, nonword repetition did not account for significant additional variation in receptive vocabulary and grammar, When performance IQ and autoregression effects were controlled, all Session I verbal ability measures predicted Session 2 vocabulary, but only Session 1 vocabulary predicted Session 2 nonword repetition. When phonological sensitivity was also controlled. Session 1 nonword repetition (leniently scored) predicted Session 2 vocabulary. Overall, these findings show qualified support for the claim that the capacity component of nonword repetition contributes directly to vocabulary in young children. They suggest that the association between nonword repetition and vocabulary in young children may, to a substantial extent, reflect a latent phonological processing ability that is also manifest in phonological sensitivity

Orthographic Rime Priming

Three experiments are described, each using a partial priming technique in which a target word was briefly preceded by a masked trigram. The relative strength of priming effects was assessed by comparing the difference in target word naming times between unprimed and primed trials in different priming conditions. Experiment 1 replicated previous work in demonstrating stronger priming when the target word was primed by the orthographic rime than when the prime constituted otherwise comparable word-final trigrams that do not constitute orthographic rimes. Experiment 2 compared orthographic, phonological rime, and control primes. Only orthographic rime primes reliably increased target word naming speed, although the priming effect was less selective with longer prime durations. In Experiment 3 priming was observed for both orthographic rime and phonological rime primes shown for 150 msec. However, stronger priming was observed with orthographic rime primes. These experiments demonstrate that orthographic rime priming effects do not simply reflect the activation of an intact subunit of the target word articulation program

The development of orthographic rimes as units of word recognition

The current study used the orthographic rime frequency effect as a means of investigating the development of, and individual differences in, children′s ability to use orthographic rimes as functional units of reading. Sets of pseudowords were constructed, varying in the frequency of their constituent orthographic rimes. Experiment 1 investigated the orthographic rime frequency effect in a large sample of first-grade children. As expected, the orthographic rime frequency effect was significant only in relatively advanced first-grade readers. Experiment 2 used a reading-level design to further investigate the orthographic rime frequency effect as a function of both age and word identification ability. Pseudoword reading accuracy was examined in poor fourth-grade readers, a younger reading-level-matched group, and a chronological age control group. Strong main effects were observed for reader group and orthographic rime frequency but these factors did not interact. Overall, these two experiments suggest that the size of the orthographic rime frequency effect reflects the operation of two factors that increase with reading ability, the size of children′s sight vocabulary (contributing primarily to the availability of orthographic rime correspondences to read pseudowords constructed from relatively common orthographic rimes), and grapheme-phoneme conversion skill (contributing primarily to the decoding of pseudowords constructed from uncommon orthographic rimes for which orthographic rime correspondences are less likely to be derived from the sight word vocabulary). In addition, Experiment 2 implicated a general phonological recoding deficit as an underlying problem in children′s word reading difficulties

Beginning readers' use of orthographic analogies in word reading

This research re-investigated the claim that beginning readers exploit information from the orthographic rime of clue words to help them to decode unfamiliar words. In Experiment 1, first-grade children were equally able to use orthographic information from the beginning, middle, and end of clue words to identify unfamiliar target words. Moreover, the improvement in reading end- (or orthographic rime-) same target words following clue word presentation reflected phonological priming. In second-grade children, with correction for retesting effects, improvement following clue word presentation for end-same and beginning-same target words was equivalent, although end-same target words improved more than middle-same target words. In Experiment 2, both first- and second-grade children were able to use orthographic information from the beginning, middle, and end of clue words to identify unfamiliar words. Clue word presentation enhanced the reading of beginning-same and end-same target words more than middle-same target words. Improvement was the same for beginning-same and end-same target words. Target word improvement following clue word presentation was greater than that for phonologically primed words only in children reading target words sharing the beginning sequence of the clue word.
