that's interesting. I will take a look!
I tend to freeze when suddenly asked to perform, whether to speak, answer a question unprepared, perform some test of skill, so I fail miserably at almost anything that is spoken direction or questions (slow visual and audio processing)
I can do much better if reading and performing written directions and explanations.
I simply don't process very fast or very completely when visual or audio ( or both) instructions, commands, requests are given. It is not a problem with memory as much as it is for me a problem of processing ... most information I get through visual demonstration or audio explanation does not lodge in my brain to begin with.
I don't believe that rapid response is a test of intelligence. (at least in my case).
