Visual Capture
In psychology, visual capture is the dominance of vision over other sense modalities in creating a percept.Grünwald, Martin. ''Human haptic perception''. Birkhauser, 2008. 657. Print. In this process, the visual senses influence the other parts of the somatosensory system, to result in a perceived environment that is not congruent with the actual stimuli. Through this phenomenon, the visual system is able to disregard what other information a different sensory system is conveying, and provide a logical explanation for whatever output the environment provides. Visual capture allows one to interpret the location of sound as well as the sensation of touch without actually relying on those stimuli but rather creating an output that allows the individual to perceive a coherent environment. One example of visual capture is known as the ventriloquism effect which refers to the perception of speech sounds as coming from a direction other than their true direction, due to the influence of ...

Comedian Terry Fator On Stage
A comedian or comic is a person who seeks to entertain an audience by making them laugh. This might be through jokes or amusing situations, or acting foolish (as in slapstick), or employing prop comedy. A comedian who addresses an audience directly is called a stand-up comedian. A popular saying often attributed to Ed Wynn attempts to differentiate the two terms: "A comic says funny things; a comedian says things funny." This draws a distinction between how much of the comedy can be attributed to verbal content and how much to acting and persona. Since the 1980s, a new wave of comedy, called alternative comedy, has grown in popularity with its more offbeat and experimental style. This normally involves more experiential, or observational reporting (e.g., Alexei Sayle, Daniel Tosh, Malcolm Hardee). As far as content is concerned, comedians such as Tommy Tiernan, Des Bishop, Kevin Hart, and Dawn French draw on their background to poke fun at themselves, while others such a ...

Michael Posner (psychologist)
Michael I. Posner (; born September 12, 1936) is an American psychologist who is a researcher in the field of attention, and the editor of numerous cognitive and neuroscience compilations. He is emeritus professor of psychology at the University of Oregon (Department of Psychology, Institute of Cognitive and Decision Sciences), and an adjunct professor at the Weill Medical College in New York (Sackler Institute). A ''Review of General Psychology'' survey, published in 2002, ranked Posner as the 56th most cited psychologist of the 20th century. Education and career In 1957, Posner received his BS in physics and in 1959, his MS in psychology from the University of Washington in Seattle, Washington. In 1962, he received his PhD in psychology from the University of Michigan in Ann Arbor, Michigan. Posner joined the faculty of the University of Wisconsin in Madison, Wisconsin as an assistant professor of psychology. In 1968, he joined the faculty of the University of Oregon in ...

Ocular Dominance
Ocular dominance, sometimes called eye preference or eyedness, is the tendency to prefer visual input from one eye to the other. It is somewhat analogous to the laterality of right- or left-handedness; however, the side of the dominant eye and the dominant hand do not always match. This is because both hemispheres control both eyes, but each one takes charge of a different half of the field of vision, and therefore a different half of both retinas (See Optic Tract for more details). There is thus no direct analogy between "handedness" and "eyedness" as lateral phenomena. Approximately 70% of the population are right-eye dominant and 29% left-eye dominant. Dominance does appear to change depending upon direction of gaze due to image size changes on the retinas. There also appears to be a higher prevalence of left-eye dominance in those with Williams–Beuren syndrome, and possibly in migraine sufferers as well. Eye dominance has been categorized as "weak" or "strong"; highly profo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multisensory Integration
Multisensory integration, also known as multimodal integration, is the study of how information from the different sensory modalities (such as sight, sound, touch, smell, self-motion, and taste) may be integrated by the nervous system. A coherent representation of objects combining modalities enables animals to have meaningful perceptual experiences. Indeed, multisensory integration is central to adaptive behavior because it allows animals to perceive a world of coherent perceptual entities. Multisensory integration also deals with how different sensory modalities interact with one another and alter each other's processing. General introduction Multimodal perception is how animals form coherent, valid, and robust perception by processing sensory stimuli from various modalities. Surrounded by multiple objects and receiving multiple sensory stimulations, the brain is faced with the decision of how to categorize the stimuli resulting from different objects or events in the physical wo ...

Lip Reading
The lips are the visible body part at the mouth of many animals, including humans. Lips are soft, movable, and serve as the opening for food intake and in the articulation of sound and speech. Human lips are a tactile sensory organ, and can be an erogenous zone when used in kissing and other acts of intimacy. Structure The upper and lower lips are referred to as the "Labium superius oris" and "Labium inferius oris", respectively. The juncture where the lips meet the surrounding skin of the mouth area is the vermilion border, and the typically reddish area within the borders is called the vermilion zone. The vermilion border of the upper lip is known as the cupid's bow. The fleshy protuberance located in the center of the upper lip is a tubercle known by various terms including the procheilon (also spelled ''prochilon''), the "tuberculum labii superioris", and the "labial tubercle". The vertical groove extending from the procheilon to the nasal septum is called the phi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mirror Box
Mirror therapy (MT) or mirror visual feedback (MVF) is a therapy for pain or disability that affects one side of the patient more than the other side. It was invented by Vilayanur S. Ramachandran to treat post-amputation patients who had phantom limb pain (PLP). Ramachandran created a visual (and psychological) illusion of two intact limbs by putting the patient's affected limb into a "mirror box," with a mirror down the center (facing toward a patient's intact limb). The patient then looks into the mirror on the side with the good limb and makes "mirror symmetric" movements, as a symphony conductor might, or as a person does when they clap their hands. The goal is for the patient to imagine regaining control over a missing limb. Because the subject is seeing the reflected image of the good limb moving, it appears as if the phantom limb is also moving. Through the use of this artificial visual feedback, it becomes possible for the patient to "move" the phantom limb and to unclenc ...

Phantom Limb
A phantom limb is the sensation that an amputated or missing limb is still attached. Approximately 80 to 100% of individuals with an amputation experience sensations in their amputated limb. However, only a small percentage will experience painful phantom limb sensation. These sensations are relatively common in amputees and usually resolve within two to three years without treatment. Research continues to explore the underlying mechanisms of phantom limb pain (PLP) and effective treatment options. Signs and symptoms Most (80% to 100%) amputees experience a phantom limb, with some of them having non-painful sensations. The amputee may feel very strongly that the phantom limb is still part of the body. People will sometimes feel as if they are gesturing, feel itches, twitch, or even try to pick things up. The missing limb often feels shorter and may feel as if it is in a distorted and painful position. Occasionally, the pain can be made worse by stress, anxiety and weather ch ...

Posner Cueing Task
The Posner cueing task, also known as the Posner paradigm, is a neuropsychological test often used to assess attention. Formulated by Michael Posner, it assesses a person's ability to perform an attentional shift. It has been used and modified to assess disorders, focal brain injury, and the effects of both on spatial attention. Method Posner's spatial cueing task has been used to measure manual and eye-movement reaction times to target stimuli in order to investigate the effects of covert orienting of attention in response to different cue conditions. In the general paradigm, observers are seated in front of a computer screen at eye level, and instructed to fixate at a central point on the screen, marked by a dot or cross. To the left and right of the point are two boxes. For a brief period, a cue is presented on the screen. Following a brief interval after the cue is removed, a target stimulus, usually a shape, appears in either the left or right box. The observer must respond ...

Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psychol ...
