About this trial

Viewing strategies are strategies used to process visual Information. Many children with visual impairment seem to lack systematic viewing strategies. However, it is unknown how viewing strategies differ between children with normal vision and children with (cerebral) visual impairment. In addition, viewing strategy training is often adopted in clinical practice, but till date there is no scientific evidence about effectiveness of this approach.

The current project has two goals: (1) to measure viewing strategies used by children with normal vision, children with ocular visual impairment and children with CVI, and (2) to evaluate whether training viewing strategies results in more efficiënt visual Information processing.
