I think, that cultural-historic psychology is very actual way of science. I work in school, and I see, that when you work with children, you must be flexible. You need huge quantity of psychology instruments.
I spoke with Alexander Venger, follower of Lev Vigotsky. He told me, that cultural-historic conception in psychological consultation is very elastic tool.
You can use some methods from different psychological schools.
Unfortunately, I don’t know enough about cultural-historic theory. But I want to know more, and I hope, that ISCAR SU is good possibility for this.
