A Radcliffe on Trent couple has launched a mobile app to assist with cognitive development.

Jane Braybrook and her partner Peter Kibble’s gaming application is based on a 1920s IQ test and was created to assist the couple’s son, who has learning disabilities, cerebral palsy, epilepsy and visual impairment.

Stencilleto uses concepts based on Grace Arthur’s Stencil Design Test, which was in use as an IQ evaluation tool up to the 1950s.

Speaking exclusively to Nottingham Post, Jane said: “You have a whole series of activities, they’re like mini IQ tests, covering all different areas. Not just one IQ but there’s 14 of them. You use them to work out what your child can do and can’t do – you learn their cognitive abilities and cognitive disabilities by doing these things.

“That means you can do little activities to improve the cognitive disabilities. If you did the IQ test again you find they have improved – that’s the theory of it. Once I got to understand the theory of it, it helped me do lots of different activities with James.”

The app includes 150 puzzles and is suitable for all ages.

Jane and Peter, a software developer, made a version for their son James in 2014. Friends, family and the learning disability charity Mencap all assisted with testing until the final version was released.

Stencilleto has been featured in The Guardian and has had over 400 hits since its launch.
