Document Summary
Attention involves shifting your focus on some type of stimulus in the environment so that your brain can process it. Attention can occur through all of the senses. Selective attention: selecting information that is most relevant to us. When we are given goals, we use selective attention. In a study, they examined eye movement of people who were given speci c visual goals (they had to look at things in a painting). We are able to select speci c sounds in the environment. Experiment psychotic listening task: participants listen to two messages in each earphone (left and right). After they listen to the clips, they are asked if they can recall anything from the message to which they were not paying attention to. They did not remember it: people lose information if they are not attending to it. However, there are exceptions: if there is a lower-level sensory change, they would notice it.
