comment Why do we become bored of stimuli after multiple exposures to it?
Check 'habituation' en.wikipedia.org/wiki/Habituation. Even though this applies to relatively low-level behaviour, it might provide some explanation for your question.

comment How do you know if it's psychosomatic or not?
True! I was referring to the psychosomatic 'seven holy cows' (gastric ulcera, colitis ulcerosa, neurodermatitis, asthma, hypertension, rheumatoid arthritis, thyreoid dysfunction) which is of course a historic classification. All those are under influence of you current state of mind and have clear somatic correlates (e.g. TPO-Antibodies for Hashimoto) but often we do not know where they are coming from. Of course there is no measure regarding how dependent on your state of mind a disease needs to be in order to be classified as psychosomatic.

comment What is the effect of ADD/ADHD on performance variability on cognitive tests over time?
I think that to assess reaction variability you do not necessarily need to test patients twice. Usually their reaction time variability is measured within one testing session. This measure is considered a more reliable hint for diagnosing the disorder then e.g. mean reaction time differences.

comment Do persons with autism have a bigger genetic predisposition to psychosis/schizophrenia?
Following the ICD-10 criteria (apps.who.int/classifications/icd10/browse/2010/en) patients cannot be diagnosed with schizophrenia and autism at the same time.

comment Are there professional cognitive science test subjects?
Or e.g. professional musicians: ncbi.nlm.nih.gov/pubmed/14642491

comment How repeatable are cognitive science findings within the same individual?
I think that this question is very broad and could be improved if you specified which area you are interested in. As Steven pointed out running the same experiment twice in human subjects is done when effects of learning are investigated. If no learning effects are expected and performance is hypothesized to be stable, researchers often investigate 'retest-reliability'. So if you google/pubmed the area you are intetested in (e.g. memory) plus 'learning' or 'retest-reliability' you will find lots of studies.

comment Analysis of parameter estimates from Ratcliff diffusion model
No - sorry for the unclear question. It is two sessions (drug & placebo) with several measurements in each session. I updated the question.
