Document Summary

One proposal focuses on the unattended input. You block processing inputs you"re not interested in. People erect a filter that shields them from potential distractors. Filter a hypothetical mechanism that would block potential distractors from further processing. The attended channel (desired info) is not filtered out receives further processing. *you also promote the processing of desired stimuli when inhibiting the processing of distractors. Perception requires some initiative and resources and work from you as you interpret incoming stimulus info. Ex. test to see large + shapes on a computer screen. Asked to see if the horizontal/vertical bar was longer. Asked to look at a fixation target the entire time. Fixation target a visual mark at which research participants point and fixate their eyes. The fixation target changed and was briefly replaced by either a triangle/rectangle/cross. Failed to see anything other than the attended + .
