Visual and orthographic information in learning to read and the influence of phonics instruction

In the Jackson and Coltheart theory of acquisition of word reading it is claimed that, near the beginning of the partial alphabetic phase of development, children have full use of abstract letter units (ALUs). This claim and less exclusive alternatives were examined. In Experiment 1, normal progress children with on average 9 months of school reading instruction, either with or without explicit phonics, read with moderate accuracy (orthographically) familiar words in upper-case letters (e.g., AND) that are visually dissimilar from their lower-case forms. Lower-case forms were read with greater accuracy but only for familiar words, there being no letter-case effect for less familiar words. Children with explicit phonics showed less impairment in reading accuracy when words were presented in upper-case form than children without such phonics. Children with on average 22 months of instruction, in Experiment 2, read relatively unfamiliar words that required some phonological mediation. Those without explicit phonics instruction read words with digraphs in unfamiliar upper case less accurately than in lower case, while those with explicit phonics showed no such letter-case difference. The results supported the view that children do not have full use of ALUs in early alphabetic reading, both children with and without explicit phonics to some extent using letter identities specific to lower case for representation of familiar words.     

Accelerating the development of reading,spelling and phonemic awareness skills in initial readers

In Experiment 1, it was found that 5-year-oldnew school entrants taught by a syntheticphonics method had better reading, spelling andphonemic awareness than two groups taughtanalytic phonics. The synthetic phonicschildren were the only ones that could read byanalogy, and they also showed better reading ofirregular words and nonwords. For one analyticphonics group the programme was supplemented byphonological awareness training; this led togains in phonemic awareness but not reading orspelling compared with the other analyticphonics group. The synthetic phonics programmewas taught to the analytic phonics groups aftertheir initial programmes had been completed andpost-tested. The group that had hadphonological awareness training did not performbetter than the other two groups when tested 15months later; this was also the case when thesame comparison was made for the the subset ofchildren that had started school with weakphonological awareness skill. Speed of letterlearning was controlled for in Experiment 2; itwas found that the synthetic phonics groupstill read and spelt better than the analyticphonics group. It was concluded that syntheticphonics was more effective than analyticphonics, and that with the former approach itwas not necessary to carry out supplementarytraining in phonological awareness.     

Sexual excitation function of hamster vaginal secretion

Sexually naive male hamsters were paired with ovariectomized females or with castrated males. On half of the trial days, the stimulus animals were scented with vaginal secretion from estrous females, and on half of the trials they were left unscented. Added vaginal secretion resulted in an increased frequency of mounting and decreased latency to mount, and an increase in the amount of time the males remained near the stimulus animals. These results demonstrate that the vaginal secretion has attractant and sexual excitant effects on naive males and thus is a source of sex pheromones. Presence of the secretion also resulted in a decrease in some measures of agonistic behavior, suggesting anti-aggressive functions as well.

     

Co‐operative Learning for Children with an Autistic Spectrum Disorder (ASD) in Mainstream and Special Class Settings: An exploratory study

The purpose of this study was to determine the effects of a cooperative learning (CL) intervention on the levels of social and task engagement of a child with autistic spectrum disorder (ASD) conducted in a mainstream class setting and a child with ASD implemented in a special needs class setting. The target children were two 8‐year‐old boys diagnosed with high functioning autism. Both children were placed in CL groups which included three typically developing peers, one male and two females. Four baseline sessions taught in a traditional teaching format and seven CL intervention sessions based on a “learning together/conceptual approach” took place. All sessions were recorded for video analysis. CL was found to be successful in substantially increasing the level of social engagement for both the child in the special needs class and the child in the mainstream class. CL was not found to facilitate task engagement. Active task engagement was found to remain relatively stable and passive task engagement was found to decrease for one child and remain stable for the other. Teacher concerns and issues relating to the practical implementation of CL in both settings are discussed.     

Developing Reading,Spelling and Phonemic Awareness Skills in Primary School Children

Phonemic awareness is beginning to become rather a buzz term in discussions about methods of teaching reading and there is widespread agreement that children need to develop this awareness in order to read effectively. It is not yet clear exactly how they should be taught this awareness and Rhona Johnston and Joyce Watson here describe their research into this issue.     

How does phonological awareness relate to nonword reading skill amongst poor readers?

This study examined phonological awareness at the level of phonemes and rhyme and related this to nonword naming ability. Poor readers were compared with 11 year old chronological-age controls and 8 year old reading-age controls. The poor reader group was impaired for chronological age in all tasks, and impaired for reading age at nonword naming and phoneme deletion. The poor readers' rhyming skills, however, were commensurate with reading age. Individual variation was observed together with exceptions to the group findings; most poor readers performed within the range of the reading-age controls on the phonological tasks and in nonword naming. Dissociations in phonological skills were evident, including indications that intact awareness of rhyme may not be a prerequisite for the development of phoneme awareness. Furthermore, phoneme awareness correlated significantly with poor readers' word and nonword reading ability, whereas rhyming skill did not. Therefore, phoneme awareness may be more important than rhyming skill in understanding reading disorders.     

The role of feedback from phonology to orthography in orthographic learning: an extension of item‐based accounts

Skilled readers were trained to recognise either the oral (n=44) or visual form (n=40) of a set of 32 novel words (oral and visual instantiation, respectively). Training involved learning the ‘meanings’ for the instantiated words and was followed by a visual lexical decision task in which the instantiated words were mixed with real English words and untrained pseudowords, and the instantiated words were to be considered as words. The phonology‐to‐orthography consistency (feedback consistency) of the instantiated words was manipulated to investigate the role of feedback from phonology in orthographic learning. Masked consonant and vowel‐preserving form primes were used in the lexical decision task as probes of orthographic learning. Feedback‐consistent instantiated words were recognised significantly faster in lexical decision than feedback‐inconsistent instantiated words, and facilitation was significantly greater from consonant‐preserving than vowel‐preserving primes for orally but not visually instantiated words. The results support the hypothesis that orthographic representations based on a consonant frame can be generated from the speech signal before encountering the printed forms, and that feedback from phonology is involved in the early stages of orthographic learning.
