Diane Hennacy Powell, MD has focused her research on a specific and unusual intersection: apparent telepathic or anomalous cognition in nonverbal autistic savants. What follows draws on the sources retrieved for this question alongside the ESP-Nexus profile page for her.

Experiments

Powell’s primary line of experimental work involves testing what she describes as telepathic communication in nonverbal autistic children — individuals who use facilitated or augmented communication methods such as Rapid Prompting Method (RPM) rather than independent speech. She presented early findings from this work at the 2014 Parapsychological Association conference under the title “Evidence for Telepathic Communication in a Nonverbal Autistic Child” ^[4], making it one of the first formal conference presentations of this research program. Her 2015 publications (Powell, 2015a and 2015b, cited internally within ^[1]) represent the next documented stage of this work.

The research described in ^[1] involved setting up controlled experiments with autistic children who were using RPM at the time of data collection — Powell notes in that source that a documentary filmmaker was present during the initial setup of these experiments, and that all her untested children at that point were RPM users ^[1]. A separate but related line of work is noted in ^[3], where Powell is mentioned in connection with Maria Welch’s spelling sessions — Welch had already worked with Powell before co-authoring with Mossbridge and Tarrant — situating Powell’s research within a broader network of investigators examining apparent anomalous cognition in nonspeaking autistic individuals ^[3].

Powell has also contributed to the broader parapsychology literature as a critical reviewer. Her 2024 review essay in the Journal of Anomalous Experience and Cognition examines Jeff Tarrant’s book Becoming Psychic, engaging with how brain-mapping techniques and meditation-based protocols are being applied to study anomalous cognition in mediums, healers, and others ^[1]. Her work has additionally been cited in the consciousness studies literature in the context of brain-as-receiver or filter theories of mind ^[6].

Methodology

Powell’s experimental protocol for the autistic-savant work is centered on a key methodological challenge: establishing genuine independence of response in participants who cannot speak and who rely on facilitated communication. Her approach, as described across the sources, involves working with children who use RPM — a method in which a trained communication partner holds a letterboard — which itself is a contested method in communication research (see Skeptical critiques below).

The design targets a scenario in which a child appears to produce information that the child’s communication partner has not directly communicated, which would constitute evidence for anomalous cognition if the independence of the response can be verified. Powell’s neuropsychiatric framework holds that certain features of autism-spectrum neurology — particularly the atypical sensory and attentional profiles associated with savant abilities — may be conducive to anomalous cognition, and her protocol design reflects this theoretical orientation.

Her broader methodological contribution includes advocacy for quantitative EEG (qEEG) as a neuroimaging tool for studying anomalous cognitive states, applying it to distinguish mediumship and related states from baseline cognition.

The retrieved sources do not include full protocol specifications — sample sizes, randomization procedures, blinding arrangements, or pre-specified analysis plans — for her primary experimental work. The retrieved excerpts show that as of the time of filming described in ^[1], experiments were being set up for the first time with untested participants, suggesting the work described there was at an early or pilot stage.

Data

The sources retrieved for this question do not contain audited quantitative outcome data — no trial counts, hit rates, effect sizes, z-scores, or p-values — from Powell’s experiments with autistic children. Source ^[1] references her 2015 publications and notes the experimental setup context, but the excerpts available do not carry the numerical results. Source ^[4] documents the conference presentation of the work but is a conference report in German and does not quote outcome statistics.

Accordingly, no figures can be reported here consistent with the grounding policy. The retrieved excerpts do not show them; the full papers cited as Powell (2015a) and Powell (2015b) in ^[1] are the appropriate sources for numerical results, and readers seeking those figures should consult those publications directly.

Skeptical critiques

What critics argue. The central methodological concern about Powell’s work is one that attaches to the participant population and communication method rather than to her experimental design in isolation. The concern, structurally similar to critiques of facilitated communication more broadly, is that apparent responses may reflect inadvertent cueing or physical guidance by the partner rather than the autistic participant’s autonomous cognition. Tostanoski, Tiger, Nicholson, Kelley, and Tarbox (2014) published an examination of RPM raising exactly these concerns about the absence of controlled evidence for message passing independent of the communication partner. If partner influence cannot be ruled out, the information a child appears to convey — including apparently anomalous information — could have a conventional origin in the partner’s own knowledge, rather than in telepathy.

What the experimental data show. The retrieved sources do not include controlled experimental data from Powell’s studies that directly address the independence question with blinded-partner or partner-absent conditions. Source ^[1] notes that the experimental sessions described were being set up for the first time with untested children, indicating the work was at a formative stage at that point. Source ^[3] references Powell’s prior work with at least one of the participants (Maria Welch’s students), but does not contain outcome statistics or blinding details. The quantitative record from Powell’s controlled experiments, including whatever controls she applied to the partner-independence problem, is not present in the excerpts retrieved.

Analysis. The partner-independence question is the structural crux of this research program: a positive result in anomalous cognition with an RPM-using participant is interpretable only if the communication partner’s knowledge can be shown not to be the source of the information. Whether Powell’s experimental designs incorporate conditions — such as keeping the partner uninformed of the target — that would satisfy this criterion is not established in the retrieved sources. Published independent replication of her controlled findings outside her own research group has not been documented in the sources available here.
