A rapid shifting of attention, usually caused by a stimulus such as a loud noise, bright light, or sudden movement. Ann treisman"s model of selective attention that proposes that selection occur sin two stages. In the rst stage, an attenuator analyzes the incoming message and lets through the attended message- and also the unattended message, but at a lower (attenuated) strength. In treisman"s model of selective attention, the attenuator analyzes the incoming message in terms of physical characteristics, language, and meaning. Attended messages pass through the attenuator at full strength, and unattended messages pass through with reduced strength. Processing that occurs automatically, without the persons" intending to do it, and that also uses few cognitive resources. Automatic processing is associated with easy or well-pracited tasks. A condition caused by brain damage in which a person has dif culty focusing attention on individual objects.
