What do you think?

Your summary roughly matches my own research and is confirmed, for what it is worth, by my own anecdotal experience.

I'll note that similar (but stronger) effects can be expected from the more direct stimulants (amphatamine, methamphetamine, etc.).

ETA: Regarding attention control, be aware that sometimes increased 'attention control' comes in the form of increased focus on the immediate task which can actually reduce the ability to switch tasks smoothly. This can affect the balance of attention you place on social details relative to task details when the situation at hand requires both.
