When subjects are presented with a picture of a person, they tend to focus their attention on the face and eyes of the individuals. However, when they are asked to draw conclusions about the individual in the image, like wealth, they shift their gaze to look at the clothes or surrounding environment. What does this test measure?
overt attention
While subjects are focusing on a blank screen, a flash of light unexpectedly appears in one of two locations. Following the flash, a target image appears on the screen.
