The ability to interpret and differentiate the spatial and temporal qualities of sensory information is known as sensory discrimination. It allows for refined organization and interpretation of sensory stimuli and contributes to skill development, learning and play that requires discrete responses (Shaaf et al., 2010:121). The individual is required to interpret the qualities of sensory information and add meaning to it. By adding meaning to sensory qualities, perceptions are formed. “In the process of discrimination, the individual must use past experiences and memories and form associations about the spatial and temporal qualities of what he or she is experiencing, and then act accordingly” (Van Jaarsveld, 2011:9). Discrimination or perception problems can occur in any sensory system. Children with sensory discrimination difficulties may not have problems with sensory modulation. However, these problems often coexist in children with sensory modulation difficulties (Case-Smith & O'Brien, 2005:379).6.2.1 Vestibular system6.2.1.1 IntroductionThe vestibular system is the primary organizer of sensory information and integrates sensory input at the brainstem level (Ayres, 1979:62). It is the unifying system and constitutes an individual's fundamental relationship with gravity and the physical world. Vestibular receptors are the most sensitive of all the sense organs, and all other types of sensations are processed in reference to this basic vestibular information (Ayres, 2005:62). The vestibular system, together with the visual and proprioceptive system, performs three main functions: provides unconscious awareness of body position and movement in space, maintains postural control, balance and balance during performance.... .. middle of paper .. ....the table in the classroom. According to her teacher, she has no difficulty with this task, but is slow in completing it because she gets distracted.6.2.1.4 Other factors influencing scoresNo other factors were found to influence scores.6.2.1.5 ConclusionFrom the above information, it is clear that Kianah has no difficulty with processing vestibular input and no vestibular difficulties are present. It is evident from his PRN and SWB score that he is efficiently processing vestibular input via vestibular receptors. He also demonstrated adequate execution of the prone extension posture, supine neck flexion, postural reactions, neck cocontraction, and dissociation of the head from the eyes. His postural tone is also within the typical range. This further confirms that he has no difficulty processing vestibular input. #
