 In attentional weighting, through practice or experience people come to systematically attend toward certain objects and properties and away from other objects and properties. Paradigm cases of attentional weighting have been shown in sports studies, where it has been found, for instance, that expert fencers attend more to their opponents’ upper trunk area, while non-experts attend more to their opponents’ upper leg area (Hagemann et al., 2010). Practice or experience modulates attention as fencers learn, shifting it towards certain areas and away from other areas.
