Gains in Literacy through the Use of a Spcially Developed Multimedia Computer Strategy Positive Findings from 13 Children with Autism

Tomas Tjus; Mikael Heimann; Keith E. Nelson

The present study investigates the use of a specially developed multimedia program for enhancing language and reading development in children with autism. Thirteen children with autism(mean chronological age 9:8 years, mental age 7:3 years and language age 5:2 years) participated in the study. All the children used the program as a supplement to their ordinary reading and language training. A quasi-experimental design that included measures of reading and phonological awareness during baseline, treatment, and follow-up phases was used throughout. Highly significant gains were observed for both reading and phonological awareness during the treatment phase. A significant effect was also observed for phonology at follow-up, but not for reading. A response time index also revealed that reading became more rapid following intervention. It is concluded that the intervention improved reading and language development and that children with autism with various cognitive abilities might benefit from a strategy that combines a motivating multimedia program with focused and positive interactions with the teacher.

Interaction Patterns Between Children and their Teachers when Using a Specific Multimedia and Communication Strategy Observations from Children with Autism and Mixed Intellectual Disabilities

Tomas Tjus; Mikael Heimann; Keith E. Nelson

This study reports on observed interaction patterns between 20 children with autism and mixed intellectual disabilities (mean chronological age = 11:4 years; language age = 4:7 years) and their nine teachers working with a specially developed multimedia program aiming to increase literacy skills. An increase in verbal expression was found over time for the total group. Children with autism also showed increased enjoyment and willingness to seek help from their teachers. Teachers for both diagnostic groups reduced their instructions on how to handle the computer during the program but the decrease was greater in the teachers for children with autism. When the total group of children was subdivided according to language age (high versus low), it appears that those with a low language age showed an increase in verbal expressiveness from start to end of training. Those with a high language age showed increased enjoyment. It is concluded that more detailed studies of the interaction patterns between teachers and children are needed, and these should be related to children’s language level as well as to diagnostic group.

Prolongation of the ejaculation latency in the male rat by thioridazine and chlorimipramine.

Sven Ahlenius; Mikael Heimann; Knut Larsson

Thioridazine (3 mg/kg) and chlorimipramine (1.5–6.0 mg/kg) prolonged the ejaculation latency and increased the number of mounts but did not change the number of intromissions preceding ejaculation. Blockade of peripheral and central noradrenaline receptors by phentolamine and phenoxybenzamine respectively resulted in a suppression of all aspects of the sexual behavior with increasing doses. dl-5-HTP (25–100 mg/kg) in combination with an inhibitor of peripheral 5-HTP decarboxylase (benserazide, 25 mg/kg) produced, like chlorimipramine and thioridazine, a prolongation of ejaculation latency and an increase in the number of mounts preceding ejaculation. Selective inhibition of 5-HT reuptake however, by zimelidine (0–20 mg/kg) or alaproclate (0–20 mg/kg) did not affect the mating behavior. At higher doses of these drugs some animals failed to initiate sexual activities. There was an increase in the postejaculatory interval but no change in the ejaculatory latency.It is concluded that the prolonged ejaculation latencies observed following treatment with thioridazine or chlorimipramine is not due to a blockade of central or peripheral adrenergic α-receptors.

Exploring Language Profiles for Children With ADHD and Children With Asperger Syndrome

Wenche Andersen Helland; Eva Biringer; Turid Helland; Mikael Heimann

Objective: The aims of the present study was to investigate communication impairments in a Norwegian sample of children with ADHD and children with Asperger syndrome (AS) and to explore whether children with ADHD can be differentiated from children with AS in terms of their language profiles on the Norwegian adaptation of the Children’s Communication Checklist Second Edition (CCC-2). Method: The CCC-2 was completed by the parents, and altogether, 77 children aged between 6 and 15 years participated in the study. Results: Communication impairments were as common in a group of children with ADHD as in a group of children with AS. Although a similar pattern appeared on most CCC-2 scales, children with ADHD and children with AS could be distinguished from each other in terms of their language profiles on the subscales assessing stereotyped language and nonverbal communication. Conclusion: Language abilities should be taken into account when standard assessments of ADHD and AS are performed and before therapies are initiated.

Little is known about use of early interventions for autism spectrum disorder in Europe. Parents of children with autism spectrum disorder aged 7 years or younger (N = 1680) were recruited through parent organisations in 18 European countries and completed an online survey about the interventions their child received. There was considerable variation in use of interventions, and in some countries more than 20% of children received no intervention at all. The most frequently reported interventions were speech and language therapy (64%) and behavioural, developmental and relationship-based interventions (55%). In some parts of Europe, use of behavioural, developmental and relationship-based interventions was associated with higher parental educational level and time passed since diagnosis, rather than with child characteristics. These findings highlight the need to monitor use of intervention for children with autism spectrum disorder in Europe in order to contrast inequalities.

The purpose of the present study was to examine the effects of three computerized interventions on the reading skills of children with reading disabilities in Grade 2. This longitudinal intervention study included five test sessions over 1 year. Two test points occur before the intervention, and three afterwards. The last follow-up was conducted 1 year after the first measurement. One hundred thirty children in Grade 2 participated in the study. Three groups of children with reading difficulties received computerized training programmes: one aimed at improving word decoding skills and phonological abilities, the second focused on word and sentence levels and the third was a combination of these two training programmes. A fourth group received ordinary special instruction. In addition, there was one comparison group with age-matched typical readers. All groups improved their reading skills. The group that received combined training showed greater improvement than the one with ordinary special instruction and the group of typical readers at two follow-ups. The longitudinal results indicate additional positive results for the group that received the combined training, the majority of students from that group being no longer judged to be needing special education 1 year after the intervention.

Imitation in Autism. A Preliminary Research Note

Mikael Heimann; E. Ullstadius; S.-O. Dahlgren; Christopher Gillberg

Previous studies have claimed that children with autism are poor imitators and a lack of imitative capacity has been included by some investigators as one early sign of autism. Presented here are results from a pilot study focusing on observed imitation after presenting 15 tasks to five children with autism (mental age 25-51 months). Imitation tasks involving simple object manipulation, vocal responses, facial and manual gestures, and object substitution were presented to each child. The performance of the children with autism is compared with (1) three normal 4-year-old children (for all 15 tasks), and (2) observations from 28 healthy 1-year-olds (for 10 of the tasks used). The findings indicate that the autistic group displayed the highest level of imitation on object manipulation and vocal tasks while object substitution, facial, and motor imitation acts seemed to be difficult for children with autism. However, the small number of children included as well as the individual variation observed among the autistic subjects precludes any definite conclusions from these pilot observations. It is hypothesized that imitation in children with autism has to be studied separately for different domains and probably also for different subgroups within the autistic population.

Effects of Bottom-Up and Top-Down Intervention Principles in Emergent Literacy in Children at Risk of Developmental Dyslexia: A Longitudinal Study

Turid Helland; Tomas Tjus; Marit Hovden; Sonja H. Ofte; Mikael Heimann

This longitudinal study focused on the effects of two different principles of intervention in children at risk of developing dyslexia from 5 to 8 years old. The children were selected on the basis of a background questionnaire given to parents and preschool teachers, with cognitive and functional magnetic resonance imaging results substantiating group differences in neuropsychological processes associated with phonology, orthography, and phoneme—grapheme correspondence (i.e., alphabetic principle). The two principles of intervention were bottom-up (BU), “from sound to meaning”, and top-down (TD), “from meaning to sound.” Thus, four subgroups were established: risk/BU, risk/TD, control/BU, and control/TD. Computer-based training took place for 2 months every spring, and cognitive assessments were performed each fall of the project period. Measures of preliteracy skills for reading and spelling were phonological awareness, working memory, verbal learning, and letter knowledge. Literacy skills were assessed by word reading and spelling. At project end the control group scored significantly above age norm, whereas the risk group scored within the norm. In the at-risk group, training based on the BU principle had the strongest effects on phonological awareness and working memory scores, whereas training based on the TD principle had the strongest effects on verbal learning, letter knowledge, and literacy scores. It was concluded that appropriate, specific, data-based intervention starting in preschool can mitigate literacy impairment and that interventions should contain BU training for preliteracy skills and TD training for literacy training.

Stable associations between behavioral problems and language impairments across childhood – The importance of pragmatic language problems

Wenche Andersen Helland; Astri J. Lundervold; Mikael Heimann; Maj-Britt Posserud

This study investigated language function associated with behavior problems, focusing on pragmatics. Scores on the Childrens Communication Checklist Second Edition (CCC-2) in a group of 40 adolescents (12-15 years) identified with externalizing behavior problems (BP) in childhood was compared to the CCC-2 scores in a typically developing comparison group (n=37). Behavioral, emotional and language problems were assessed by the Strengths and Difficulties Questionnaire (SDQ) and 4 language items, when the children in the BP group were 7-9 years (T1). They were then assessed with the SDQ and the CCC-2 when they were 12-15 years (T2). The BP group obtained poorer scores on 9/10 subscales on the CCC-2, and 70% showed language impairments in the clinical range. Language, emotional and peer problems at T1 were strongly correlated with pragmatic language impairments in adolescence. The findings indicate that assessment of language, especially pragmatics, is vital for follow-up and treatment of behavioral problems in children and adolescents.

Effects of Three Interventions on the Reading Skills of Children With Reading Disabilities in Grade 2

Stefan Gustafson; Linda Fälth; Idor Svensson; Tomas Tjus; Mikael Heimann

In a longitudinal intervention study, the effects of three intervention strategies on the reading skills of children with reading disabilities in Grade 2 were analyzed. The interventions consisted of computerized training programs: One bottom-up intervention aimed at improving word decoding skills and phonological abilities, the second intervention focused on top-down processing on the word and sentence levels, and the third was a combination of these two training programs (n = 25 in each group). In addition, there were two comparison groups, 25 children with reading disabilities who received ordinary special instruction and 30 age-matched typical readers. All reading disabled participants completed 25 training sessions with special education teachers. All groups improved their reading skills. The group who received combined training showed higher improvements than the ordinary special instruction group and the typical readers. Different cognitive variables were related to treatment gains for different groups. Thus, a treatment combining bottom-up and top-down aspects of reading was the most effective in general, but individual differences among children need to be considered.
