SensePhysiological capacitySensation consists of signal collection and transduction.The five major senses that most higher organisms have are: Sight (vision), Hearing (audition), Smell (Olfaction), Touch (Somatosensation), and Taste (Gustation).A sense is a biological system used by an organism for sensation, the process of gathering information about the surroundings through the detection of stimuli.
Motion perceptionMotion perception is the process of inferring the speed and direction of elements in a scene based on visual, vestibular and proprioceptive inputs. Although this process appears straightforward to most observers, it has proven to be a difficult problem from a computational perspective, and difficult to explain in terms of neural processing.
Visual perceptionVisual perception is the ability to detect light and use it to form an image of the surrounding environment. Photodetection without image formation is classified as light sensing. In most vertebrates, visual perception can be enabled by photopic vision (daytime vision) or scotopic vision (night vision), with most vertebrates having both. Visual perception detects light (photons) in the visible spectrum reflected by objects in the environment or emitted by light sources.Depth perceptionDepth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions. Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. Depth perception arises from a variety of depth cues.
PerceptionPerception (from Latin perceptio 'gathering, receiving') is the identification, interpretation and organization of sensory information, in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.Optical illusionIn visual perception, an optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation.
RealityReality is the totality of existence or what all existing entities have in common. It is often contrasted with appearance, opposing what is with what seems to be, although the accuracy and fundamentality of this contrast are disputed. Various criteria for distinguishing real from unreal entities have been proposed, including causal powers, mind-independence, and being non-illusory.
Gestalt psychologyGestalt psychology, gestaltism, or configurationism is a school of psychology, and a theory of perception, that emphasizes psychologically processing entire patterns (and "configurations"), not merely individual components of situations or events separately. It emerged in the early twentieth century in Germany and Austria as a rejection of basic principles of Wilhelm Wundt's and Edward Titchener's elementalist and structuralist psychology.
HallucinationA hallucination is a perception in the absence of an external context stimulus that has the compelling sense of reality.
Stimulus (physiology)The light from the lamp (1.) functions as a detectable change in the plant's environment. As a result, the plant exhibits a reaction of phototropism—directional growth (2.) toward the light stimulus.Look up stimulus in Wiktionary, the free dictionary.
Human bodyThe human body is composed of many different types of cells that together create tissues and subsequently organs and then organ systems. The external human body consists of a head, hair, neck, torso (which includes the thorax and abdomen), genitals, arms, hands, legs, and feet. The internal human body includes organs, teeth, bones, muscles, tendons, ligaments, blood vessels and blood, lymphatic vessels and lymph.
MindThe mind is that which thinks, feels, perceives, imagines, remembers, and wills. It covers the totality of mental phenomena, including both conscious processes, through which an individual is aware of external and internal circumstances, and unconscious processes, which can influence an individual without intention or awareness. The mind plays a central role in most aspects of human life, but its exact nature is disputed.Subjective constancySubjective constancy or perceptual constancy is the perception of an object or quality as constant even though our sensation of the object changes. While the physical characteristics of an object may not change, in an attempt to deal with the external world, the human perceptual system has mechanisms that adjust to the stimulus.*As an Amazon Associate I earn from qualifying purchases.
