Document Summary
Inattentional blindness: not noticing something even though it is in clear view, usually caused by failure to pay attention to the object or where it is located: changed blindness: difficulty in detecting changes in scenes. We take into account regularities in the environment. Unexpected stimuli will likely draw our attention via movement or sound: endogenous vs. exogenous. Endogenous: automatic attraction of attention by sudden visual or auditory stimulus. Endogenous: consciously determined attention: overt attention: attention with eye movement. Saccades: rapid movement of the eyes from one place to another. Fixations: short pauses on points of interest: studied by using an eye tracker, two factors that determine how people shift their attention by moving their eyes, bottom-up: based primarily on physical characteristics of the stimulus. Stimulus salience: areas that stand out and capture attention. Scene schema: knowledge about what is contained in typical scenes. Helps guide fixations from one area of a scene to another: covert attention: attention without eye movement.
