Document Summary
Attention: process of focusing on specific objects or locations within a scene and ignoring others. We constantly monitor our environment by shifting attention overtly and covertly. What directs our attention: stimulus salience. Physical properties that make a particular object or location noticeable. Attentional capture: when attention due to stimulus salience causes an involuntary shift of attention. Could be to warn of danger or stand out in a scene. Saliency map: map of a visual display that takes into account characteristics. Usually, first few fixations are on light areas, but then scanning becomes influenced by top-down processing that depend on the observer: selection based on cognitive factors. Might focus on aspects of a scene that are more interesting to the person, some things could have more meaning. Top-down processing is associated with scene schemas, which is observer"s knowledge about what is contained in typical scenes.
