The term is commonly but not exclusively used in the context of autism autism spectrum disorder s. It may appear in otherwise healthy children. It may be necessary for only one sense to be bombarded by stimulation stimuli to affect that sense as well as the other senses and the thinking process. The most common type occurs when more than one sense is stimulated. For example, a person might be watching television when someone comes in and asks a question the watcher might fail to respond because he or she simply does not register it, or realizes the question has been asked but gets confused and doesn t know whether to answer the question or concentrate on the television.

It is a form of ataxia loss of coordination physiology coordination caused not by cerebellum cerebellar dysfunction but by loss of sensory input into the control of movement. Sensory ataxia is distinguished from ataxia cerebellar ataxia by the presence of near normal coordination when the movement in question is visually observed by the patient, but marked worsening of coordination when the eyes are closed. Sensory ataxia also lacks the associated features of cerebellar ataxia such as pendular tendon reflexes , scanning dysarthria , pathologic nystagmus nystagmus and broken pursuit eye movements.

Unreferenced stub auto yes date December 2009 Sensory threshold is a theoretical concept used in psychophysics . A stimulus physiology stimulus that is less intense than the sensory threshold will not elicit any sensation. Methods have been developed to measure thresholds in any of the senses. Several different sensory thresholds have been defined Absolute threshold the lowest level at which a stimulus can be detected. Recognition threshold the level at which a stimulus can not only be detected but also recognised. Just noticeable difference Differential threshold the level at which an increase in a detected stimulus can be perceived. Terminal threshold the level beyond which a stimulus is no longer detected. Aviation use . When related to motion in any of the possible six degrees of freedom 6 DoF , the fact that sensory thresholds exist is why it is essential that aircraft have blind flying instruments. Sustained flight in cloud is not possible by seat of the pants cues alone since errors build up due to aircraft movements below the pilot s sensory threshold, ultimately leading to loss of control. In flight simulators with motion platforms, the motion sensory thresholds are utilised in the technique known as acceleration onset cueing . This is where a motion platform, having made the initial acceleration that is sensed by the simulator crew, the platform is re set to approximately its neutral position by being moved at a rate below the sensory threshold and is then ready to respond to the next acceleration demanded by the simulator computer.

The discipline requires panels of human assessors, on whom the products are tested, and recording the responses made by them. By applying statistical techniques to the results it is possible to make inferences and insights about the products under test. Most large consumer goods companies have departments dedicated to sensory analysis. Sensory analysis can mainly be broken down into three sub sections Effective testing dealing with objective facts about products Affective testing dealing with subjective facts such as preferences Perception the biochemical and psychological aspects of sensation Effective testing This type of testing is concerned with obtaining objective facts about products.

wiktionary Sensory gating is a process by which the brain adjusts its response to stimuli ref cite pmid 18801443 ref . It is a largely automatic process. When one stimulus is presented, there is a response. But when it is followed by a second stimulus soon after, the response to the second stimulus is blunted. This is an adaptive mechanism to prevent overstimulation. It helps the brain focus on a stimulus among a host of other distractors. The mechanism of sensory gating involves feed forward and feed back inhibition of the stimulus perceived. It involves GABA ergic and Alpha 7 nicotinic receptor mediated inhibition of the pyramidal cell pyramidal neurons in the cornu ammonis CA3 region of the hippocampus . Sensory gating is thought to be disturbed in Schizophrenia ref cite pmid 16469942 ref .

A sensory cue is a statistic or signal that can be extracted from the sensory input by a perceiver, that indicates the state of some property of the world that the perceiver is interested in perceiving. Senses Sensory cues include Visual perception visual cues, Hearing sense auditory cues, Somatosensory system tactile cues, Haptic technology haptic cues, olfaction olfactory cues, and so on. Sensory cues play an important role in theories of perception, especially theories of appearance how things look . Concept Helmholtz 1821 1894 and Egon Brunswik Brunswik 1903 1955 are two scientists who were known for cue theories. Helmholtz held that the visual system constructs visual percepts through a process of unconscious inference , in which cues are used to make probabilistic best guesses about the state of the world. For Helmholtz and most modern perceptual scientists , a visual percept is the manifestation of this process. Brunswik formalized Helmholtz s ideas with the lens model , which breaks the system s use of a cue into two parts the ecological validity perception ecological validity of the cue, which is its correlation with a property of the world, and the system s utilization of the cue. In these theories, accurate perception requires both the existence of cues with sufficiently high ecological validity to make inference possible, and that the system actually utilizes these cues in an appropriate fashion during the construction of percepts. Some examples of visual cues include The eyes vergence angle is a distance cue Changes in shading across an object provide a shape cue Some examples of auditory cues include Interaural intensity difference IID is a sound source direction cue Difference in sound arrival time interaural timing difference or ITD is another sound source direction cue Cue combination is an active area of research in perception , that seeks to understand ... also Stimulus psychology DEFAULTSORT Sensory Cue Category Perception Category Sensory system ... more details
