“Attention is malleable. We can intensify it, shift it either voluntarily or involuntarily. We can soften it, diffuse it. We can deploy global attention toward tangible external objects, or to their intangible attributes. We can direct attention internally to retrieve items that we have stored in memory. We can sustain attention by infusing a component of motivation, either from the top-down (by intention) or by much more subtler means related to our habitual ongoing attitudes.”
