Open research questions

How can assessment practices better distinguish motor-planning differences, sensory-motor challenges, communication barriers, learning differences, and intellectual disability?

Why this matters: Better assessment could reduce misdiagnosis, prevent people from being routed into inappropriate default programs, and help teams identify when the main barrier is motor access rather than lack of understanding.

What behaviors are often misread as low capability, inattention, refusal, anxiety, or lack of understanding, but may actually reflect whole-body apraxia or unreliable motor output?

Why this matters: Research could help clinicians, educators, and families recognize commonly missed signs of motor-planning difficulty. This could reduce lifelong underestimation and help teams ask a better question: not only what a person can show, but what supports they need to show what they know.

Examples that deserve careful study include inconsistent performance, delayed responses, difficulty initiating movement, trouble imitating gestures, waving spontaneously but not when prompted, smiling naturally but not on request, understanding a direction but being unable to organize the movement needed to respond, or performing a skill one day and appearing unable to access it the next.

What are the longitudinal motor-planning correlates of progress in text-based communication?

Why this matters: If motor planning is part of the bottleneck, progress should be studied over time rather than judged from isolated snapshots. This could clarify which supports are associated with stronger communication trajectories.

How can neurorehabilitation strategies used with stroke, brain injury, ALS, Parkinson's, cerebral palsy, and other motor conditions be adapted for nonspeaking people with global apraxia or unreliable motor output?

Why this matters: Neurorehabilitation already studies motor learning, cueing, pacing, positioning, fatigue, partner support, and access accommodations. Applying those models could help researchers study nonspeaking communication access through an established rehabilitation lens.

What role does regulation play as a precondition for motor performance and communication access?

Why this matters: If regulation is necessary for reliable movement, then communication breakdown cannot automatically be interpreted as refusal, inattention, or lack of comprehension. This research could shift practice toward access-based supports.

How do motor planning, sensory processing, emotional regulation, and communication interact?

Why this matters: This could help explain why communication may be reliable in one setting and collapse in another. It would support more realistic models of communication that account for sensory load, stress, fatigue, timing, posture, and environmental demands.

Which supports help different nonspeakers build reliable communication access, and under what conditions?

Why this matters: Nonspeaking people are not a single group with identical needs. Research could help identify which combinations of motor coaching, sensory regulation, initiation support, AAC, spelling, typing, partner training, and practice help which people, in which situations, and why.

How much instruction, practice, partner training, and time are needed before text-based communication becomes more reliable across people and settings?

Why this matters: Many nonspeaking people are judged too quickly. Dosage and partner-effect studies could help define what a fair trial actually requires before concluding that an approach is or is not working.

What predicts successful fading from physical, gestural, visual, or close partner support toward lighter support or greater independence?

Why this matters: The field needs evidence about when support can be reduced safely, when it should not be reduced, and what protects communication while support changes.

How do communication partners, settings, pressure levels, and sensory environments affect communication reliability?

Why this matters: A person may communicate more effectively with one partner or in one environment than another. Research could show that context is part of access, not just background noise.

Why does physically stabilizing, holding, positioning, or supporting a communication tool help some nonspeaking people communicate more effectively?

Why this matters: Similar supports are accepted in many motor disability contexts. Research could clarify when physical support functions as legitimate accommodation, when it creates risk, and what safeguards best protect both access and authorship.

Can replicable eye-tracking protocols document gaze-before-point patterns in naturalistic communication conditions?

Why this matters: Stronger eye-tracking methods could provide more objective evidence of visual planning, intention, and visual-motor coordination during communication.

Can EEG, fNIRS, and other neurocognitive tools help assess language comprehension in nonspeaking autistic adults previously assessed as profoundly intellectually disabled?

Why this matters: Standard testing often depends on speech, pointing, imitation, or other motor responses. Neurocognitive methods could reveal comprehension that behavioral tests miss and reshape diagnostic, educational, and service decisions.

How can researchers measure communication reliability without creating test conditions that overwhelm the motor, sensory, and regulatory systems being studied?

Why this matters: High-pressure testing may not accurately reflect what a nonspeaker understands or can communicate under supportive conditions. Research should account for motor access, sensory load, anxiety, fatigue, partner familiarity, and regulation.

Are nonspeaking people or people who use communication partners more likely to make inaccurate or false allegations than other disability populations or others who rely on communication support?

Why this matters: Other populations who use interpreters, caregivers, advocates, or communication support are not automatically dismissed because support is involved. Comparative research could test whether nonspeaking people are being held to a different standard and help build due-process safeguards that protect against influence without stripping people of voice or credibility.

What safeguards best protect authorship, dignity, and access at the same time?

Why this matters: The field needs evidence-based standards that do not treat total independence as the only valid endpoint. Better documentation, partner training, transparency, multiple communication opportunities, individualized assessment, and careful review of possible influence could protect against harm without silencing people who need support to communicate.

What outcomes change over 10 or more years when nonspeaking people gain meaningful communication access?

Why this matters: Long-term outcome studies could examine education, employment, mental health, autonomy, relationships, self-advocacy, health care access, community participation, and quality of life. Without long-term data, systems can continue treating communication access as optional rather than life-changing.

What happens over the long term when nonspeakers are presumed competent, given meaningful communication access, and supported based on motor needs rather than assumptions about ability?

Why this matters: This question goes beyond any single communication technique. It asks what changes across a life when people are no longer treated as incapable.

How does adopting a presume-competence mindset affect families, support teams, and communities around nonspeakers with profound support needs?

Why this matters: Families of people with profound support needs often experience isolation, loneliness, exhaustion, grief, and disconnection from typical community life. Research could examine whether presuming competence, pursuing communication access, and connecting with others who share that belief improves hope, belonging, stress, loneliness, and quality of life.

How can nonspeaking people be included as active collaborators and contributors in research?

Why this matters: Research priorities improve when the people most affected help shape the questions, methods, interpretation, and dissemination. Including nonspeaking people as contributors would make the field more rigorous, more ethical, and more relevant.
