#1) Autism #2) Asperger #3) PDD-NOS
What are the 3 symptom clusters and which cluster is found in all forms of Autism?
#1) Social Impairment (found in all forms) #2) Language #3) Stereotyped
How might measures of mirror neurons help to demonstrate the efficacy of Autism treatments and the early diagnosis of autism?
- conditioning good social behaviors - Looking at MU suppression before training and after training - Early diagnosis: 2 years old at earliest and early diagnosis matters because the earlier you can start behavior analysis, the better the outcomes
What is the Broken Mirror Hypothesis of Autism? What types of impairments might "broken mirrors" cause.
Broken Mirror Hypothesis states that the mirror neurons in the brain are broken in people with autism. Impairments: - Poor perspective taking - Autistic people get no Mu suppression while watching an action, others do - Impairments with empathy
How did Oberman and colleagues demonstrate a dysfunctional mirror neuron system in people with autism?
Oberman put EEG cap on people with autism, as well as a non-autistic control group. Then he had them watch a video of a hand doing tasks, they would proceed to preform same task. - Those with autism got Mu suppression when preformed action, and zero when they watched. - Those without autism got about half the Mu suppression while watching, and the rest while preforming.
