One way that SFQ could help with memory and attention is through reducing anxiety that interferes w/ memory and attention. If there is too much going in the brain, too much processing, then some information doesn't get remembered. Too much relaxation and a person can feel sleepy; too much anxiety and the brain doesn't work as well as
it can. All this is from my training as a psychologist.
I often feel a pleasant relaxed mind state when I practice SFQ. Let us know what your experience is about that or about memory as you practice SFQ.
Peace to you,
