Non word Repetition and Reading Skills in Children Who Are Deaf and Have Cochlear Implants

Reading skills in hearing children are closely related to their phonological processing skills, often measured using a nonword repetition task in which a child relies on abstract phonological representations in order to decompose, encode, rehearse in working memory and reproduce novel phonological patterns. In the present study of children who are deaf and have cochlear implants, we found that nonword repetition performance was significantly related to nonword reading, single word reading and sentence comprehension. Communication mode and nonverbal IQ were also found to be correlated with nonword repetition and reading skills. A measure of the children's lexical diversity, derived from an oral language sample, was found to be a mediating factor in the relationship between nonword repetition and reading skills. Taken together, the present findings suggest that the construction of robust phonological representations and phonological processing skills may be important contributors to the development of reading in children who are deaf and use cochlear implants.     

A Longitudinal Study of Audiovisual Speech Perception by Children with Hearing Loss Who have Cochlear Implants

The present study investigated the development of audiovisual speech perception skills in children who are prelingually deaf and received cochlear implants. We analyzed results from the Pediatric Speech Intelligibility (Jerger, Lewis, Hawkins, & Jerger, 1980) test of audiovisual spoken word and sentence recognition skills obtained from a large group of young children with cochlear implants enrolled in a longitudinal study, from pre-implantation to 3 years post-implantation. The results revealed better performance under the audiovisual presentation condition compared with auditory-alone and visual-alone conditions. Performance in all three conditions improved over time following implantation. The results also revealed differential effects of early sensory and linguistic experience. Children from oral communication (OC) education backgrounds performed better overall than children from total communication (TC backgrounds. Finally, children in the early-implanted group performed better than children in the late-implanted group in the auditory-alone presentation condition after 2 years of cochlear implant use, whereas children in the late-implanted group performed better than children in the early-implanted group in the visual-alone condition. The results of the present study suggest that measures of audiovisual speech perception may provide new methods to assess hearing, speech, and language development in young children with cochlear implants.     

Individual Differences in Effectiveness of Cochlear Implants in Children Who Are Prelingually Deaf: New Process Measures of Performance

The efficacy of cochlear implants in children who are deaf has been firmly established in the literature. However, the effectiveness of cochlear implants varies widely and is influenced by demographic and experiential factors. Several key findings suggest new directions for research on central auditory factors that underlie the effectiveness of cochlear implants. First, enormous individual differences have been observed in both adults and children on a wide range of audiological outcome measures. Some patients show large increases in speech perception scores after implantation, whereas others display only modest gains on standardized tests. Second, age of implantation and length of deafness affect all outcome measures. Children implanted at younger ages do better than children implanted at older ages, and children who have been deaf for shorter periods do better than children who have been deaf for longer periods. Third, communication mode affects outcome measures. Children from "oral-only" environments do much better on standardized tests that assess phonological processing skills than children who use Total Communication. Fourth, at the present time there are no preimplant predictors of outcome performance in young children. The underlying perceptual, cognitive, and linguistic abilities and skills emerge after implantation and improve over time. Finally, there are no significant differences in audiological outcome measures among current implant devices or processing strategies. This finding suggests that the major source of variance in outcome measures lies in the neural and cognitive information processing operations that the user applies to the signal provided by the implant. Taken together, this overall pattern of results suggests that higher-level central processes such as perception, attention, learning, and memory may play important roles in explaining the large individual differences observed among users of cochlear implants. Investigations of the content and flow of information in the central nervous system and interactions between sensory input and stored knowledge may provide important new insights into the basis of individual differences. Knowledge about the underlying basis of individual differences may also help in developing new intervention strategies to improve the effectiveness of cochlear implants in children who show relatively poor development of oral/aural language skills.     

Word Learning in Children Following Cochlear Implantation

An experimental procedure was developed to investigate word-learning skills of children who use cochlear implants (CIs). Using interactive play scenarios, 2- to 5-year olds were presented with sets of objects (Beanie Baby stuffed animals) and words for their names that corresponded to salient perceptual attributes (e.g., "horns" for a goat). Their knowledge of the word-object associations was measured immediately after exposure and then following a 2-hour delay. Children who use cochlear implants performed more poorly than age-matched children with typical hearing both receptively and expressively. Both groups of children showed retention of the word-object associations in the delayed testing conditions for words that were previously known. Our findings suggest that although pediatric CI users may have impaired phonological processing skills, their long-term memory for familiar words may be similar to children with typical hearing. Further, the methods that developed in this study should be useful for investigating other aspects of word learning in children who use CIs.     

Mothers' Speech to Hearing‐Impaired Infants and Children With Cochlear Implants

This study investigated the effects of age, hearing loss, and cochlear implantation on mothers' speech to infants and children. We recorded normal‐hearing (NH) mothers speaking to their children as they typically would do at home and speaking to an adult experimenter. Nine infants (10–37 months) were hearing‐impaired and had used a cochlear implant (CI) for 3 to 18 months. Eighteen NH infants and children were matched either by chronological age (10–37 months) or hearing experience (3–18 months) to the CI children. Prosodic characteristics such as fundamental frequency, utterance duration, and pause duration were measured across utterances in the speech samples. The results revealed that mothers use a typical infant‐directed speech style when speaking to hearing‐impaired children with CIs. The results also suggested that NH mothers speak with more similar vocal styles to NH children and hearing‐impaired children with CIs when matched by hearing experience rather than chronological age. Thus, mothers are sensitive to hearing experience and linguistic abilities of their NH children as well as hearing‐impaired children with CIs.     

Development of Pre-Word-Learning Skills in Infants with Cochlear Implants

Families of infants who are congenitally deaf now have the option of cochlear implantation at a very young age. In order to assess the effectiveness of early cochlear implantation, however, new behavioral procedures are needed to measure speech perception and language skills during infancy. One important component of language development is word learning-a complex skill that involves learning arbitrary relations between words and their referents. A precursor to word learning is the ability to perceive and encode intersensory relations between co-occurring auditory and visual events. Recent studies in infants with normal hearing have shown that intersensory redundancies, such as temporal synchrony, can facilitate the ability to learn arbitrary pairings between speech sounds and objects (Gogate & Bahrick, 1998). To investigate the early stages of learning arbitrary pairings of sounds and objects after cochlear implantation, we used the Preferential Looking Paradigm (PLP) to assess infants' ability to associate speech sounds to objects that moved in temporal synchrony with the onset and offsets of the signals. Children with normal hearing ranging in age from 6, 9, 18, and 30 months served as controls and demonstrated the ability to learn arbitrary pairings between temporally synchronous speech sounds and dynamic visual events. Infants who received their cochlear implants (CIs) at earlier ages (7-15 months of age) performed similarly to the infants with normal hearing after about 2-6 months of CI experience. In contrast, infants who received their implants at later ages (16-25 months of age) did not demonstrate learning of the associations within the context of this experiment. Possible implications of these findings are discussed.     

Effects of Phonotactic Probabilities on the Processing of Spoken Words and Nonwords by Adults with Cochlear Implants Who Were Postlingually Deafened

Probabilistic phonotactics refers to the frequency with which segments and sequences of segments occur in syllables and words. Knowledge of phonotactics has been shown to be an important source of information in recognizing spoken words in listeners with normal hearing. Two online tasks (an auditory same-different task and an auditory lexical decision task) were used to examine the use of phonotactic information by adults who were postlingually deafened who have received cochlear implants. The results of the experiments showed that cochlear implant patients with better word recognition abilities (as measured by the Northwestern University Auditory Test No. 6 (NU-6) produced patterns of results that were similar to the pattern of results obtained from listeners with normal hearing in Vitevitch and Luce (1999). This finding suggests that cochlear implant patients with better word recognition abilities use lexical and sublexical representations to process spoken words, much like listeners with normal hearing. In contrast, cochlear implant patients with poor word recognition abilities could not differentiate between stimuli varying in phonotactic probability and lexicality, suggesting that less distinct representations are used by these patients to process spoken words. The implications of these results for outcome assessments and clinical interventions are discussed.     

The Role of Self-Efficacy in Reading Achievement of Young Children in Urban Schools

Academic self-efficacy has been found to be important in predicting educational success among older children and adolescents, but scant work has addressed this for very young children. This study explored (a) whether academic self-efficacy appears to be associated with reading achievement among children in urban elementary schools in primary grades, (b) whether one can differentiate between concepts of self-efficacy and self-concept within this age group, and, if so, which has more predictive power for reading achievement, and (c) whether student motivation and classroom behavior mediate the relationship between self-efficacy and reading. Findings from random-effect multi-level modeling show that children in primary grades can differentiate between self-efficacy and self-concept, and it was task-specific self-efficacy tha1t significantly influenced reading achievement. Of the two possible mediators, student motivation significantly mediated the relationship between self-efficacy and reading achievement. Implications for the role of school social workers in enhancing achievement among young, vulnerable children are discussed.     

Moving Towards Work

SUMMARY

The present study sought to investigate the effects of employment on low-income single black mothers and their preschool children. The sample included 90 mothers from New York City communities who were welfare recipients in 1996, and followed two years later. At follow-up, 53 of the 90 mothers were employed. The findings indicated that lower levels of depressive affect or financial strain were not predictive of entry into the work force. However, once employed, mothers reported less depressive symptoms than those not working. Attaining more education predicted better outcomes for mothers and their children, and provided more of an opportunity to be successful in the job market. For example, having more education was associated with gaining employment, exiting welfare, having stable employment, earning higher wages, and better reading abilities in children. Maternal employment was beneficial to children, as mothers who entered the work force had children who performed better in math achievement at follow-up, after controlling for maternal socioeconomic characteristics and school readiness at baseline. Implications of the findings will be discussed.     

Use of Partial Stimulus Information by Cochlear Implant Users and Listeners with Normal Hearing in Identifying Spoken Words: Some Preliminary Analyses

An error analysis of the word recognition responses of cochlear implant users and listeners with normal hearing was conducted to determine the types of partial information used by these two populations when they identified spoken words under auditory-alone and audiovisual conditions. The results revealed that the two groups used different types of partial information in identifying spoken words under auditory-alone or audiovisual presentation. Different types of partial information were also used in identifying words with different lexical properties. In our study, however, there were no significant interactions with hearing status, indicating that cochlear implant users and listeners with normal hearing identify spoken words in a similar manner. The information available to users with cochlear implants preserves much of the partial information necessary for accurate spoken word recognition.     

RESPONSE BIAS IN A POPULAR INDICATOR OF READING TO CHILDREN

This paper examines the hypothesis that parents exaggerate their reading with children aged 3 to 5 when asked typical single-item questions and that the extent of exaggeration is greater for better-educated parents. It examines differences in parental reporting of reading to children that may result from differences in response bias. It examines whether differences in reading with children by race/ethnicity, income, and family structure hold up after controlling for maternal education and other factors. Finally, it examines whether any bias we find affects the relationship between reading and achievement test scores. Data are from the Child Development Supplement to the Panel Study of Income Dynamics, a nationally representative sample of children and their parents who were asked detailed questions about their lives and activities in 1997.     

The gift of speech: why parents implant their children

In Australia cochlear implantation of profoundly deaf infants, babies, and young children is approaching 100% saturation. Why do parents choose to implant rather than learn Auslan? What is the Deaf community’s reaction to this and how will it change Sign as a living language? In this article, the author is a Deaf parent who chose to implant her Deaf child. When she initially published in a news outlet on this topic the reaction was quite heated: how terrible a parent you must be if you are denying your child Sign! This article explains the reasoning behind that decision to implant, taking issue with the notion that giving a child an ‘extra ability’ of speech means that you do not love them as they are. Nothing is natural, but everything is acquired or augmented – in all children.     

Adolescent Pregnancy's Intergenerational Effects: Does an Adolescent Mother's Education Have Consequences for Her Children's Achievement?

Although substantial work has examined the influence of adolescent pregnancy on mothers’ developmental outcomes, few studies have investigated the influence of adolescent mothers’ educational attainment on their children's achievement. This article examined the reading and math achievement trajectories of children born to adolescent and nonadolescent mothers with various levels of educational attainment. Results demonstrate that higher levels of maternal education predicted children's higher initial achievement at kindergarten and growth in achievement through eighth grade. The achievement of children with adolescent mothers, however, never reaches parity with the achievement of their peers with nonadolescent mothers. Race also predicted achievement differences. Black and Latino children of adolescent mothers were at greater risk for underachievement.     

Preventing failure at school

This paper considers early educational interventions aimed at preventing school failure. It begins with a typology of prevention and intervention, then goes on to consider four specific examples of preventive interventions all aimed at avoiding or alleviating academic failure at school. (1) The High Scope pre-school programme for disadvantaged children aimed at providing a ‘better start at school'. (2) Reading Recovery, a targeted intervention aimed at getting children who show early reading difficulties ‘back on course'. (3) A Focused Literacy Programme for improving the reading of all children in disadvantaged neighbourhoods of the inner city. (4) ‘Parent involvement' programmes to improve the reading of all children in primary school through support for literacy at home. Each of the intervention strategies is described and criticised in terms of effectiveness, acceptability and generalisation. Copyright © 1999 John Wiley & Sons, Ltd.     

Documenting the lived experiences of young adult cochlear implant users: ‘feeling’ sound,fluidity and blurring boundaries

This article draws on qualitative research that explored the lived experiences of 16 young adult cochlear implant users. The original study focused on the emerging generation of young adult implant users and presented their stories as a means of furthering research into the experiences of living with, and using, implant technology as part of everyday life. This article will explore the process of being ‘switched on’, the adaptation to the new version of sound, and the users’ perceptions of the positive and negative aspects of living with their technology. The findings indicate that activating the implant technology can produce a range of sounds that are both heard and felt by the user. Furthermore, the process of learning to live with the technology highlights the fluidity of the cochlear implant experience and the blurring of boundaries between the (deaf) body and its technology.     

Teen Mothers: Marriage,Cohabitation, and Educational Achievement

This study examines the proportions of ethnically diverse low-income teen mothers who are cohabitating and/or married to the father of their child(ren) at approximately 14, 24, and 36 months after birth of their child. In addition, the relationship between marital status and education among teen mothers is explored. At 36 months after giving birth, 60% of mothers were not living with or married to the fathers of their children. Hispanic mothers were the most likely, and African-American mothers the least likely, to be married to the father at each of the three time points. For Hispanic teen mothers, being married at 14 months was related to lower educational achievement.     

The Temporal Effects of Divorces and Separations on Children’s Academic Achievement and Problem Behavior

This article provides an examination of the effects of the divorce and separation process on children’s academic achievement and problem behavior over time. By using child fixed effects and establishing a baseline period that is four or more years prior to a family disruption, I can examine how children are affected in different periods relative to the disruption and whether any negative effects subside, persist, or escalate as time passes from the disruption. With a sample of 7- to 14-year-olds, I find that children are affected at least two to four years before the disruption; reading test scores are most affected; and for reading comprehension, the negative effects persist and even escalate as time passes from the disruption.     

Basic Reading Through Dance program. The impact on first-grade students' basic reading skills

This study evaluates the effectiveness of an arts-based educational program, Basic Reading Through Dance. Basic Reading Through Dance is a 20-session, curriculum-based reading intervention for first-grade students developed by Whirlwind, a not-for-profit organization. There were a total of 721 first-grade students from Chicago public schools who participated in the study, with 328 students from 6 schools receiving the program and 393 students from 9 schools serving as controls. The program was designed to improve reading skills, as assessed by the PhonoGraphix Test, such as code knowledge (alphabet sounds) and phoneme segmentation (separating letter sounds within spoken words). Results suggest that the students who participated in the program improved significantly more than control students on all reading skills that were assessed.     

Minority Students in Mathematics: The Reading Skills Connection

The research discussed in this paper examined the performance of male and female minority students in the subject areas of mathematics and reading. The subjects for the study consisted of over one thousand junior and senior high school students who were enrolled in fifty-nine different mathematics classes at eleven different schools across the country. Most of the students–69 percent–were of non-minority background. Blacks represented the largest portion (87.6 percent) of the minority segment. The study had four objectives: (1) to compare the performance of minority students on achievement tests in mathematics with their performance on achievement tests in reading; (2) to compare the performance of minority students on achievement tests in mathematics and reading with the performance of non-minority students in those tests; (3) to compare the performance of male minority students with that of female minority students; and (4) to consider the relationship between performance on achievement tests in reading and mathematics to course grade in mathematics. The overall purpose of the study was to further our understanding of the type of academic preparation occurring among pre-college students from minority backgrounds.     

FAMILY STRUCTURE TRANSITIONS AND CHILD ACHIEVEMENT

This article uses prospective data from the National Longitudinal Survey of Youth 1979 to investigate how children in divorced and never-married-mother families vary in reading and math achievement after parental remarriage. These are compared to children who remain in never-married, divorced, and continuously married families. Results based on growth curve modeling indicate that children remaining in single-parent families resulting from divorce or nonmarital births have lower achievement scores than children from married families. Maternal education and income account for all of the adverse effects of family structure on reading achievement, while maternal education, income, and children's home environment can explain the negative relationship between single parenting and math scores. We conclude that parental remarriage may have more benefits for children than previous studies have suggested.
