About Down's Syndrome : Validating a Novel Visual Processing Questionnaire in neurodiverse children and young people

Can you help with this study?

The aim of this study is to develop a new questionnaire for parents and carers (the ViPro) to find out more about visual processing behaviours in neurodiverse children and young people.

The research team hope that identifying differences in visual processing could increase understanding of the pathway from basic vision to behaviour, and aid in identification of difficulties or differences in sensory processing.

The team are looking for parents of children between the ages of 4 and 15 years to fill out a 20-minute online questionnaire.

Your child does not have to have a neurodevelopmental condition (e.g. autism spectrum condition, attention deficit hyperactivity disorder, or epilepsy) for you to take part.

Children who have Down’s Syndrome have higher rates of visual difficulties, and some also experience additional neurodevelopmental conditions such as autism spectrum condition (ASC) or attention deficit hyperactivity disorder (ADHD).

Children who have ASC or ADHD often have differences in sensory processing, such as sensory seeking (e.g. showing a fascination with shiny surfaces and busy patterns) or avoidance (e.g. having a strong preference for shady over brightly lit spaces).  How children process sensory information can have a significant impact on their daily functional skills, play, social interactions and emotional well-being.  A toddler, for example, who is hypersensitive to touch may be reluctant to engage in messy play, while a teenager who is hypersensitive to sound may become very anxious at a noisy party.
