In psychology, attention is understood to be the allocation of brain resources for processing conscious perceptions and for thinking, which can be done deliberately by consciously focussing one’s attention on one’s external or internal environment or externally when something draws attention to itself, so to speak.
Concentration is the long-term maintenance of a level of attention and the deliberate focussing of this attention on a specific activity, stimulus or similar (Stangl, 2009).
