Human processing - what people do with new information - occurs in an infinite variety of ways, all of which range between reflection and action.
To process new information through reflection means mentally transforming the new information by using personal knowdlege to structure, order and intellectualize the information.
We also call this place in the process: "3 o'clock".
To process new information through action means applying ideas to the external world. For example to try testing and manipulating an idea for the purpose of making it useful and practical.
We also call this place in the process: "9 o'clock".
We all do both - but some people prefere to spend most time at "3 o'clock" others at "9 o'clock". Regardless it is the interplay between the "watching" of reflection and the "doing" of action which is crucial as it provides the impetus for acting on internal ideas.
