Don't worry too much, this seems to be the norm. I spent 18 months in the lab earning practical experience but nothing from that will form part of my thesis. Even the reading I did moved on. I'm sure your on track.
Shouldn't you have that practical experience before you started? I don't really see how you finish a PhD in 3 to 4 years if you spent 1.5 years without making any progress with the thesis.
I am not a psychologist, but I would expect that you had a broad education in psychology and that you now have to get the knowledge for your special research field in psychology. Do you really need a year to read the essential stuff? Sounds a bit boring too ;)
