Longitudinal Studies of IQ Stability in Children with Childhood Autism – Literature Survey, Summarized Sep 21, 2010

Therapy that is started intensely and early may be able to raise the IQ of children with autism.

This literature reviewed looked to see whether IQ changes or stays the same in children with autism. All of the studies reviewed in this article looked to see the effect of a certain therapy on IQ score. The authors found that most children with autism are first diagnosed with an IQ between borderline intelligence to mild mental retardation. The IQ score that was most often measured was the total IQ (as opposed to an IQ subscore such as verbal IQ). Most studies found that the IQ score stayed the same even after the therapy.

Change in Autism Classification with Early Intervention: Predictors and Outcomes, Summarized Sep 14, 2010

Children with autism who have decent receptive language skills are most likely to improve with early intervention.

This study looked at a wide range of factors that might result in a change in autism diagnosis after intervention. The study focused on groups of children whose autism changed or stayed stable after intervention. They then looked to see what types of children were most likely to change their autism status. They found that the child’s age, level of skills, and parents’ ages were not linked to changes in autism status. The authors found that those children who were improved post-intervention improved in both verbal and visual skills.

Naturalistic Observations of Elicited Expressive Communications of Children with Autism: An Analysis of Teacher Instructions, Summarized Aug 10, 2010

Verbal prompt and modeling may be useful in eliciting communication in low verbal and nonverbal students.

The purpose of this study was to collect data on how children with severe autism communicate in the classroom. The author found that even though the 32 students were non-verbal or had few words, they did communicate in the classroom. They did this rarely (about once every six minutes). The children with the most severe autism spoke the fewest words. Almost all of the teachers were able to prompt communication from the students.

The Effect of Teaching PECS to a Child with Autism on Verbal Behavior, Play, and Social Functioning, Summarized Jul 8, 2010

Picture Exchange Communication System (PECS) may help children with autism learn to speak and play and be more social.

The purpose of this case study was to teach communication skills to a three-year-old child with autism using PECS, and to see if PECS training led to wider behavior changes. The therapists taught PECS using highly preferred items to help the child want to learn. The study found that PECS training came with increased verbal behaviors from the child. This result agrees with other research that says that spoken words increase after PECS training. The authors also found that the child was more social and played more after PECS training.
