Judge No Evil, See No Evil: Do People’s Moral Choices Influence to Whom They Visually Attend?

Abstract

Eye-tracking technology: Tracking gaze Eye-tracking technology allows researchers to record and analyse a range of information about what people visually attend to and how they process visual information. For example, eye-tracking technology can be used to document the order in which people attend to different features of a visual image, whether they gaze at (i.e. fixate on) particular elements of an image (or completely avoid them), and, if so, the frequency and duration of these gazes. It can also be used to track more basic processing information, such as pupil dilation (see Chapter 2 in this volume) and gaze 'directionality' (i.e. whether people's eyes tend to gaze in particular directions first or most dominantly). There are a variety of ways that researchers can track people's eye movements and gaze direction. For example, there are free-standing systems that are typically placed in front of the person-and, thus, require that the person remain still in one location, typically while viewing visual stimuli on a screen-as well as systems that can be secured to a person's head, and are thus more mobile, able to move with the person and track eye movement and gaze more organically, during motion (see suggested readings for reviews).
