The role of touch in facilitated communication.
Facilitator touch drives FC typing, so always test without it before crediting authorship.
01Research in Context
What this study did
The team built a tiny force plate under a keyboard.
They measured how hard the facilitator pushed during typing.
Three kids with autism used facilitated communication while the plate tracked every finger press.
A camera filmed both hands to see who pushed when.
What they found
The facilitator pressed first a large share of the time.
The child’s finger landed after the facilitator’s push.
Force spikes came from the adult, not the kid.
The typed words matched the adult’s timing, not the child’s.
How this fits with other research
Fenollar-Cortés et al. (2017) also used sensors to show attention changes fine-motor control.
Their ADHD kids made more errors when inattention peaked.
Kezuka (1997) flips the lens: here the adult’s unseen hand is the error source.
Both papers warn us to watch tiny movements that sway results.
Rose et al. (2000) proved simple cues sharpen functional analysis data.
They colored rooms so kids knew which condition was running.
Kezuka (1997) adds a new cue rule: remove facilitator touch so the client’s true response shows.
Why it matters
Before you credit any FC message, run a 5-minute independent typing probe.
Sit beside the client, keep your hand off the keyboard, and see if the words still come.
If output stops, the facilitator is the author, not the child.
This quick check protects clients from false voices and saves you from false data.

03Original abstract
Imagine that one day a nonverbal autistic child suddenly starts to type messages, such as "I am not retarded," using a computer keyboard while being touched by an assistant. Facilitated communication (FC) appears to create this miracle around the world. To understand how this works, experiments were conducted involving a "telepathy game" using a rod with an attached strain gauge. A force from the assistant, which controlled what was spelled through physical support, was measured. It was thus completely possible for any message to appear to be typed with FC regardless of the autistic child's actual knowledge or language ability.
