My experience is quite similar to what is described in the first article—no coffee leads to better concentration for me. The caffeine ‘boost’ I was talking about reduces my concentration but makes me more inclined to action—I found it useful for breaking through procrastination periods. The effect of Red Bull on me is similar but more pronounced.
The effect seems to be physical, but I don’t rule out placebo (and frankly, it’s fine with me either way.)
