Early identification of cognitive delay is important to increase early intervention for at-risk children. Such identification is largely reliant on parent-report questionnaires, such as the Parent Report of Children's Abilities, Revised 1 or the Ages and Stages Questionnaire. 2 Depending on the screening results, children may have the opportunity to complete full developmental assessments conducted by trained assessors. These include the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III), 3 which has strong language, administrator, and cultural biases. 4 Recent advances in touchscreen technology have the potential to be harnessed for neurodevelopmental assessment that is more child-driven and less administrator-dependent than parentreport questionnaires or full developmental batteries. 5,6 This is increasingly feasible as a testing tool, given growing empirical evidence that children acquire the fine motor skills required for touchscreen use before preschool years, across languages and cultures, including Ireland, the UK, Spain, and Malawi. [6][7][8] The use of a lightweight portable touchscreen assessment may offer more accessible cognitive testing for children with mobility, motor, or sensory issues, who may currently struggle to engage in physically or sensory-demanding tasks typically involved in developmental batteries. 3,9
