Dual sensory loss is the simultaneous loss of two senses. Research has shown that 6% of non-institutionalized older adults had a dual sensory impairment, and 70% of severely visually impaired older adults additionally suffered from significant hearing loss. [7] Vision and hearing loss both interfere with the interpretation and comprehension of ...
Sensory processing disorder (SPD), formerly known as sensory integration dysfunction, is a condition in which multisensory input is not adequately processed in order ...
Sensory deprivation or perceptual isolation [1] is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and the ability to know which way is down.
impairment of tactile sensation; impairment of proprioception, i.e. postural sensation and sensation of passive movement; sensory and visual neglect syndromes, i.e. inability to pay attention to things in certain parts of the person's sensory or spatial environment; this may be as extreme as denial of a limb
long-term physical, mental, intellectual or sensory impairments which in interaction with various barriers may hinder [a person's] full and effective participation in society on an equal basis with others. [3] Disabilities have been perceived differently throughout history, through a variety of different theoretical lenses.
Sensory hearing loss is caused by abnormal structure or function of the hair cells of the organ of Corti in the cochlea. [disputed – discuss] Neural hearing impairments are consequent upon damage to the eighth cranial nerve (the vestibulocochlear nerve) or the auditory tracts of the brainstem.
A deficit known as cortical astereognosis of the receptive type describes an inability to make use of tactile sensory information for identifying objects placed in the hand. For example, if this type of injury effects the hand region in the primary somatosensory cortex for one cerebral hemisphere, a patient with closed eyes cannot perceive the ...
Sensory substitution is a change of the characteristics of one sensory modality into stimuli of another sensory modality. A sensory substitution system consists of three parts: a sensor, a coupling system, and a stimulator. The sensor records stimuli and gives them to a coupling system which interprets these signals and transmits them to a ...
