First, a short personal note to make you understand why this is important to me. To make a long story short, the son of a friend has some atypical form of autism and language troubles. And that kid matters a lot to me, so I want to become stronger in helping him, to be able to better interact with him and help him overcome his troubles.
But I don't know much about psychology. I'm a computer scientist, with a general background of maths and physics. I'm kind of a nerd, social skills aren't my strength. I did read some of the basic books advised on Less Wrong, like Cialdini, Wright or Wiseman, but those just give me a very small background on which to build.
And psychology in general, autism/language troubles in particular, are fields in which there is a lot of pseudo-science. I'm very sceptical of Freud and psychoanalysis, for example, which I consider (but maybe I am wrong?) to be more like alchemy than like chemistry. There are a lot of mysticism and sect-like gurus related to autism, too.
So I'm bit unsure on how from my position of having a general scientific and rationality background I can dive into a completely unrelated field. Research papers are probably above my current level in psychology, so I think books (textbooks or popular science) are the way to go. But how to find which books on the hundreds that were written on the topic I should buy and read? Books that are evidence-based science, not pseudo-science, I mean. What is a general method to select which books to start in a field you don't really know? I would welcome any advise from the community.
Disclaimer: this is a personal "call for help", but since I think the answers/advices may matter outside my own personal case, I hope you don't mind.
UPDATED: It has been pointed out that Autism Speaks still funds research looking for the supposed link to vaccines! People have resigned over this. Do not give your money to this organization.
Some books on autism:
There is also the 100 Day Kit from Autism Speaks.
You're right. There is a lot of mis-information out there about autism. The problem isn’t you’re a non-expert. It’s that the “experts” really don’t know.
You can't do controlled studies. You can't say to one parent, “Give Jonny OT, but don't give him speech therapy or ABA (or horse therapy), and come back in 10 years,” and tell another parent, "Just give Jonny horse therapy."
That said, a mainstream view is forming. Get speech therapy to help with pragmatics. Get some form of behavioral therapy (ABA, RDI, etc.) Get occupational therapy to help with sensory. Don’t try to do all of this on your own. You want good therapists.
A bad therapist is worse than no therapist. Until you've had a few, it can be hard to tell these apart. There are a lot of bad therapists.
Some other generally accepted good uses your of money (probably!), include:
Depending on the part of the world in which you live, the school component might be free. You would do well to keep in mind that free is not be the same as good, or even appropriate. (Remember: No bad therapists!)
I would also get the child in to see a developmental peditrician to create a treatment plan. Your pediatrician probably knows less about autism than you do. You want a specialist.
There are lots of other things you can try, but it’s best to think of these as unproven/highly experimental. I, myself, would probably add another hour of OT or speech (or create a cash buffer) before trying anything else.
