PSYC 305L Lecture Notes - Lecture 16: Inattentional Blindness, Hemispatial Neglect, Change Blindness
Document Summary
In typical experiments, participants are asked to pay attention to one of these inputs (the attended channel) and are urged to ignore the other. Shadowing: a task in which research participants are required to repeat back a verbal input, word for word, as they hear it, some unattended inputs are detected, perceiving and the limits on cognitive capacity, filter. A hypothetical mechanism that would block potential distractors from further processing: inattentional blindness, fixation target. A visual mark (such as a dot or a plus sign) at which one points one"s eyes (or fixates). Fixation targets are used to help research participants control their eye position: inattentional blindness. A pattern in which perceivers either do not see or take a long time to see large-scale changes in a visual stimulus. This pattern reveals how little people perceive, even from stimuli in plain view, if they are not specifically attending to the target information: early versus late selection, early selection.
