A case-control evaluation of sensory profile among preschool children affected by autism spectrum disorder
2019
Background: Autism spectrum disorders (ASD) are neurobehavioral syndromes caused by a developmental disorder, biologically determined, with a very early onset and deficit mainly related to social communication and interaction.There is a considerable amount of literature on ASD suggesting abnormal sensory experience as a basic symptom, as also reported by the DSM-5 and ICD-10.The current case-control study aimed to investigate the sensory perception skills in preschool children affected by ASD compared with a control group of typical developing children.Materials and methods: The study sample was composed of 42 children, subdivided into two groups: 21 ASD (12 males); 21 typical developing (T…
New determinants of olfactory habituation
2017
AbstractHabituation is a filter that optimizes the processing of information by our brain in all sensory modalities. It results in an unconscious reduced responsiveness to continuous or repetitive stimulation. In olfaction, the main question is whether habituation works the same way for any odorant or whether we habituate differently to each odorant? In particular, whether chemical, physical or perceptual cues can limit or increase habituation. To test this, the odour intensity of 32 odorants differing in physicochemical characteristics was rated by 58 participants continuously during 120s. Each odorant was delivered at a constant concentration. Results showed odorants differed significantl…
