Assesment of perceptual functions

Perceptual functions are the specific mental functions of recognizing, processing and interpreting sensory stimuli; they cover auditory, visual, olfactory, gustatory, tactile and visuospatial perception. Impairments in sensory perception and processing can impact vision, hearing or movement, and can also contribute to problems with behaviour. Assessment of perceptual functions uses interviewing, observation or clinical tests to determine the presence and/or severity of impairment in perceptual functions, ascertain their impact on functioning, and inform care planning, including the need for a referral or follow-up.
