Technological supports to promote choice opportunities by two children with fragile X syndrome and severe to profound developmental disabilities.

Two boys with fragile X and profound disabilities could not speak or use their hands.

The team taped small optic sensors near each boy’s favorite toy and on a second toy.

When the boy looked at a toy, the sensor triggered music or lights for one minute.

A multiple-baseline design showed if the boys learned to "choose" by looking.

Both boys soon looked at toys on purpose to turn on the music or lights.

Each boy smiled and laughed more while stereotypic hand-flapping dropped.

The sensors gave real choice without needing words, hands, or staff help.

Stasolla et al. (2013) saw the same happiness jump when three kids with cerebral palsy used bigger custom switches.

Together the papers show the tool can change—optic eyes, big buttons, Wii remotes—yet the payoff stays.

Carr et al. (2002) ran an earlier microswitch study with adults. They also saw higher happiness, proving the feel-good effect spans ages.

Armas Junco et al. (2025) moved the idea into group homes. Adults who got more daily choices gained self-determination, hinting that early sensor practice may set up later life gains.

You can tape a $5 sensor to any preferred item and give non-verbal clients instant control. No tablets, no programming degree. Try it during downtime or stereotypy-prone moments. One look = one reinforcer. Watch happiness rise and problem behavior fade while the learner finally calls the shots.
