Change Blindness And The Field Of Human Sensation And Perception

Good Essays

Change blindness is a phenomenon in attention where drastic changes to a scene can go unnoticed. This is important to the field of Human Sensation and Perception because it helps illustrate how a visual scene is processed. Specifically it shows how even if there is direct attention to a scene, there are times when drastic changes can occur without perception of the change occurring. With extensive research already conducted illustrating this effect, new research has recently been conducted studying different types of scene changes in the hopes of understanding which changes are easier or harder to notice. The results of these studies were quantified by the measurement of change detection time (usually reported in seconds). This subset of change blindness research has far-reaching practical applications, especially in the field of security and law enforcement. By applying the knowledge of which type of stimuli lead to longer change detection times training programs could be developed that allow this population to improve their observation skills.

Literature Review

A study conducted by Gusev, Mikhaylova, and Utochkin used the flicker paradigm as described by Rensink et. al (1997) to observe the effect of different stimuli on change blindness. The different stimuli studied were number of objects, object organization, object shape, appearance/disappearance of an object, object shift, color change of an object, and increasing the interstimulus interval (blank screen
