When is it advised to use conscious and/or spontaneous operant conditioning?

Hello!

//posted this question on two Facebook groups, but are still looking for some insights:

An issue that often came up while developing an audio neurogame was to decide how much users should be told about the mapping between classified signals and control parameters i.e. how conscious or spontaneous should the operant condition be.

Should users know, be conscious about every aspect of the reward system e.g. what is a positive or negative reward or should conditioning happen spontaneously, without users being aware of the mapping at all?

Perhaps how much users should know about the system might depend on the goals e.g. if users are required to focus, perhaps knowing exactly what is happening in the system is a good idea, but, if they are required to relax, let go, perhaps they should not know anything about the mapping.

I imagine there have been discussions about this - could you help, point me to some literature, perhaps papers?

Would it perhaps be a good idea to run a quick survey on this?

Thanks! k
