Document Summary
Class 3, lecture 6, chapter 4: paying attention. Other studies of attention focus on a phenomenon known as change blindness, the inability of observers to detect changes in scenes they are looking directly at. See if you can detect the differences between the following pairs of pictures: Similar effects of change blindness occur when people fail to notice continuity errors in films. In a particularly striking example, participants failed to notice when the person asking them for directions changed identity (following a brief interruption by two people carrying a door). Early studies of attention focused on when the perceiver selects the desired input. According to the early-selection hypothesis, the unattended input receives little to no analysis: based on. Both the early- and late-selection hypotheses capture part of the truth: for instance, the study discussed earlier showing that unattended stimuli have effects on perception seems to be a case of late selection.
