Feature binding is accomplished by a stage of processing known as attentive processing, which it operates on only a few items at a time in a serial manner. o Attentive processing combines features into a whole object through attention. Pop-out: a feature that grabs attention. High-fidelity percept of the world is not possible because: o Visual information is degraded as it moves through the visual organs to the brain. o Information from all areas of viewed space is not equally represented in the brain. There is a decrease in visual processing for peripheral information. Perceptual Filling-In Blind spot: A region in the eye where the optic nerve leaves the retina; it does not contain any photoreceptors. (Check out Figure 3.19 it is UNREAL!!!) Perceptual Completion = Filling-in : the brain compensates for missing information with information it receives from the receptors surrounding the blind spot from the other eye. 3.6 Perceptual Whole Objects: Gestalt Psychology Gestalt psychology: A branch of psychology that focuses on dealing with wholes rather than parts. Bi-stable figures: Images from which two separate percepts can be formed. Holistic: Focusing on the whole configuration of an object. Atomistic: Focusing on features/elements. Gestalt psychology is holistic and not atomistic. Oraganizational principles are rules that explain how we perceive whole objects or events from individual parts. We group elements to perceive a whole. Organizational Principles Principles of experience: A principle of Gestalt organization stating that elements are grouped based on the prior experience and knowledge of the observer.

Figure-ground segmentation : Perceptual organization of a scene such that one element becomes the foreground and the other elements become the background. o The region that we recognize tends to be one from prior experience. Denotivity: The degree to which an object is meaningful and familiar to an individual. o High in denotivity = very meaningful/familiar = easily recognizable. Principle of proximity : Things that are near one another are grouped together. Principle of closure : Things that form closed shapes are grouped together. Principle of good continuation : Things that form continuous lines are grouped together. Principle of common fate : Things that are moving in the same direction are grouped together. Limitations of Gestalt Perception In the real world, there are different factors that are constantly interacting with each other and the Gestalt movement didn’t specify the way we will or will not group objects under these conditions. It was assumed to apply to all aspects of perception. This is the Gestalt’s error : The assumption that whole objects should always dominate over the elements of an image.
