Document Summary
Breadth of attention, 2 things transpire from the way in which we generally talk about attention: It implies limited capacity (we don"t pay attention to everything that happens out there) It doesn"t tell us when, where or how the selective filter come into play. It doesn"t tell us how the selective filter works (is it strict or a bit leakier: looking to erps (eeg) for help to study attentional processing, eeg is known for its good temporal resolution. Erps: if the participant is paying attention to the flickering stimulus at the top left, then. Negative deflection that occurs in response to face stimuli about 170ms after viewing it: estimate of occurrence of n170 component varied systematically with those 2 conditions, whenever participants were asked to remember faces, N170 was systematically faster than when participants were asked to ignore faces: results: from a healthy aging perspective.
