Document Summary
Glossary: attention: any of the very large set of selective processes in the brain. Ipsilesional field: the visual field on the same side as a brain lesion: attention deficit hyperactivity disorder (adhd): a quite common childhood disorders that can continue into adulthood. If the gist, or meaning, of the scene is not altered, quite large changes can pass unnoticed. Inattentional blindness: a failure to notice - or at least to report - a stimulus that would be easily reportable if it were attended. Summary: attention is a vital aspect of perception because we cannot process all of the input from our senses. The term attention refers to a large set of selective mechanisms that enable us to focus on some stimuli at the expense of others. Though this chapter talked almost exclusively about visual attention, attentional mechanisms exist in all sensory domains. In vision, it is possible to direct attention to one location or one object.
