Variability in ADHD, Autism and Tourette's Syndrome.

Hilde Geurts has conducted research on response times (RT) variability in various clinical (ADHD, Autism, Tourette's Syndrome) and a non-clinical group (normal controls). The RT's were analyzed using various methods, among which we performed a spectral decomposition of the variance across trials. Here's the complete R script that computed the various statistics: whatwedidexactly.R.
