The effects of phonological and morphological training on speech perception scores and grammatical judgments in deaf and hard-of-hearing children

Seventeen primary school deaf and hard-of-hearing children were given two types of training for 9 weeks each. Phonological training involved practice of /s, z, t, d/ in word final position in monomorphemic words. Morphological training involved learning and practicing the rules for forming third-person singular, present tense, past tense, and plurals. The words used in the two training types were different (monomorphemic or polymorphemic) but both involved word final /s, z, t, d/. Grammatical judgments were tested before and after training using short sentences that were read aloud by the child (or by the presenter if the child was unable to read them). Perception was tested with 150 key words in sentences using the trained morphemes and phonemes in word final position. Grammatical judgments for sentences involving the trained morphemes improved significantly after each type of training. Both types of training needed to be completed before a significant improvement was found for speech perception scores. The results suggest that both phonological and morphological training are beneficial in improving speech perception and grammatical performance of deaf and hard-of-hearing children and that both types of training were required to obtain the maximum benefit.     

The effects of psychotherapy on behavior problems of sexually abused deaf children.

This study assessed the effectiveness of a broad based psychotherapeutic intervention with a sample of 72 children sexually abused at a residential school for the deaf. An untreated comparison group emerged when about half of their parents refused the offer for psychotherapy provided by the school. Treated and untreated children were randomly assigned to two assessment groups: those who participated in a pretreatment assessment and those who did not. Houseparents at the residential school used the Child Behavior Checklist (CBC) to rate the pretreatment assessment children before treatment and all 72 children one year after the implementation of psychotherapy. Children receiving therapy had significantly fewer behavior problems than children not receiving therapy. There was a differential response to therapy on the basis of sex. Boys receiving therapy had significantly lower scores on the following CBC scales than the no treatment group: Total, Internal, External, Somatic, Uncommunicative, Immature, Hostile, Delinquent, Aggressive, and Hyperactive. There were no differences on the Schizoid and Obsessive scales. Girls receiving therapy had significantly lower scores than the no treatment group on the following CBC scales: Total, External, Depressed, Aggressive, and Cruel. There were no differences on the Internal, Anxious, Schizoid, Immature, Somatic, and Delinquent scales.     

Comparing motor development of deaf children of deaf parents and deaf children of hearing parents

Deaf children of Deaf parents perform better academically (Ritter-Brinton & Stewart, 1992), linguistically (Courtin, 2000; M. Harris, 2001; Vaccari & Marschark, 1997), and socially (Hadadian & Rose, 1991; M. Harris, 2001) than Deaf children of hearing parents. Twenty-nine Deaf children in residential schools were assessed to determine if a significant difference also exists in motor development between Deaf children with Deaf parents and Deaf children with hearing parents. In the locomotor area, 78.6% of Deaf children of Deaf parents and 73.3% of Deaf children of hearing parents reached or surpassed average performance levels. In regard to object control, 92.9% of Deaf children of Deaf parents and 93.3% of Deaf children of hearing parents reached or surpassed average performance levels. The study results show no significant difference between the motor development of Deaf children of Deaf parents and Deaf children of hearing parents.     

The effects of extraneous speech on visual vigilance performance of children

First-grade males performed a 30-min visual vigilance task under 5 conditions of auditory background stimulation. The 5 conditions consisted of (1) continuous conversation, in which subjects listened to a tape of conversation spliced so that there were no intervals of silence lasting longer than 3 sec; (2) continuous reverse, in which subjects heard the continuous conversation tape played in reverse; (3) intermittent conversation, in which subjects heard alternating segments of conversation and silence; (4) intermittent reverse, in which subjects heard alternating segments of reverse conversation and silence; and (5) silence control. Compared with silence or continuous stimulation, intermittent stimulation produced better detection regardless of whether or not it was meaningful. High achievers made more correct detections than low achievers, but only in the second and third time periods. Few subjects made errors of commission.     

The effects of prior information upon perceptions of exceptional children

Students in a university special education course were shown three identical videotapes of children in a school setting. The subjects were randomly divided into three groups, each receiving different written background information (“positive,” “neutral,” or “negative”) prior to viewing the videotapes. It was found that the variations in written information had significant effects upon the subjects' perceptions of the children's behavior, and upon the degree to which the children were regarded as able to function successfully in a regular classroom. These findings suggest that attitudes toward exceptional children are influenced by the way in which prior information, such as that contained in a child's educational records, is presented. Teacher and peer acceptance of exceptional children can be increased if information is presented in a realistic and positive manner.     

The pragmatic skills of profoundly deaf children

This study investigated the ability of normally hearing students and two groups of profoundly deaf students, one using oral and one using signed communication, to employ a series of pragmatic skills required for effective face-to-face interaction. Specifically considered were the ability of listeners to request clarification, the ability of speakers to respond to requests, and the strategies speakers use at times of communication breakdown. Differences were found between the two groups suggesting that the profoundly deaf students had difficulty consistently using appropriate, productive pragmatic behaviors in their face-to-face dyadic interactions.     

The comparison of performance by sex of deaf children on the WISC-R

The Performance Scale of the WISC-R was administered to 60 female and 65 male hearing-impaired subjects. The only significant sex difference found was on the Coding subtest, with females outperforming males by a mean scaled score difference of 1.77 points (t = −3.087, p<.01). Subtest intercorrelational results suggest that deaf females possessed significantly better visual-motor coordination and speed, while males demonstrated better spatial analysis and synthesis skills. A principal factor analysis procedure yielded only one factor for each sex. The high degree of factorial similarity between the female and male samples indicated that the underlying construct being measured by the WISC-R Performance subtests does not differ by gender.     

The prevalence of behavior problems in deaf children

The appropriateness of the Behavior Problem Checklist for deaf children has been established in various studies. The objective of this study was to use the Behavior Problem Checklist to assess the prevalence of behavior problems in deaf children and to compare these results to earlier studies of behavior problems of hearing and hearing-impaired children. A lesser prevalence of behavior problems was found than in some earlier studies of deaf children. Results were somewhat more consistent with past findings regarding children with no hearing problems. Comparisons by sex found, as in earlier studies, that boys tended to evidence more behavior problems than girls.
