Document Summary

1- what is covert orienting: covert- attention is being moved but nobody can see you do it, overt- turning your body or eyes so ppl can see. 2- studying covert orienting with location cueing. 4- properties of the attentional focal point. Covert- you make and nobody can see it. Why not just move your eyes: efficiency. Takes of a second to make an eye movement (saccades) 2 spotlights: where our attention is, where our vision is. Helmholtz: studied attention orienting in 1800"s, windbox (black) Visible pin hole (hole on other end) Electrical connections that briefly make a spark inside the box: wanted to know if his vision was clearest where his eyes were pointing (fixation point) or where our attention is directed. Saw more letters in attentional focal point: steps of experiment. Sperling (1960"s: auditory location cueing, 3 letters presented and then auditory tone when letters taken away, high tone (top row), medium tone (middle row), low tone (bottom row)
