James G. Matlock, PhD — Experiments and Data

James G. Matlock is an anthropologist and research fellow at the Parapsychology Foundation whose work centers on reincarnation case research, past-life memory, and related anomalous experiences. The sources retrieved for this question cover several distinct lines of investigation; the overview of his ESP-Nexus profile provides the broadest synthesis.

Experiments

Matlock’s investigative work falls across four identifiable lines, each represented in the retrieved sources.

1. Longitudinal follow-up of canonical reincarnation cases

The most recent retrieved study is a 2026 paper co-authored with Khattar Hatoum and Carole Louie, re-examining Rabih Elawar — one of the subjects in Ian Stevenson’s foundational case collection — at age sixty ^[1]. The study revisits the original case record, interviews Elawar directly, and compares his current recollections against Stevenson’s documented claims, treating the case as a naturalistic longitudinal observation of memory retention and loss.

2. After-death communications (ADCs) from non-human animals

A 2025 paper co-authored with Bethany Hilton compiled and analyzed accounts of apparent post-mortem contact from deceased pets and other animals ^[2]. This is a two-sample study comparing an earlier and a later collected corpus of accounts, examining the timing, phenomenology, and context of reported animal ADCs.

3. NDE-triggered past-life memory retrieval

Two 2025 publications address the intersection of near-death experiences (NDEs) and past-life memory. One is a single detailed case study of a Norwegian woman (“Astrid”) whose NDE was followed by flashbacks and dreams of what she took to be a pre-Christian Viking-era life ^[3]. The second is a pilot study examining a broader sample of NDE experiencers who subsequently reported past-life memories ^[4], using a structured questionnaire instrument alongside narrative interview.

4. Dream-sourced past-life memories

A 2024 paper investigates the case of Angela Grubbs, whose dreams — recorded before any verification attempt — appeared to contain verifiable details corresponding to the life of a historical figure, Francine Donovan ^[5]. A separate 2024 paper examines a subject identified as E.C., who reported a series of past-life visions and intuitive impressions surfacing in middle adulthood, with apparent behavioral influences traceable to childhood ^[6].

Methodology

Matlock works primarily within the naturalistic case-study tradition of parapsychology rather than controlled laboratory experiments. Several methodological features recur across the retrieved work.

Pre-verification documentation. In the Angela Grubbs case ^[5] and in the NDE pilot study ^[4], Matlock emphasizes that memories or impressions were recorded — in writing or interview — before any attempt was made to verify them against historical records. This is the field’s standard control against retrospective distortion.

Structured claim scoring. In the Elawar follow-up ^[1] and the Grubbs case ^[5], individual memory claims are tabulated item by item and coded as correct, incorrect, or unconfirmed. This allows a granular accounting of what can and cannot be checked against independent evidence.

Comparative timing analysis. In the animal ADC study ^[2], Matlock and Hilton used chi-square analysis to test whether the timing of reported animal visits differed between grief-related contacts and visits serving other purposes (greeting dying loved ones, providing support, or warning of danger), treating timing as the primary quantitative variable.

Standardized NDE measurement. In the NDE pilot study ^[4], Matlock used the Greyson NDE Scale to characterize the depth and type of NDE for each participant, grounding subjective accounts in a validated psychometric instrument.

Memory-system framework. Across several papers ^[1], ^[5], ^[6], Matlock explicitly frames apparent past-life memories within mainstream cognitive memory research — invoking concepts such as episodic memory, reminiscence bumps, recency effects, implicit memory, and memory cueing — and tests whether past-life memory patterns conform to or diverge from known present-life memory patterns.

Data

Because no structured quantitative evidence block was supplied for this question, the figures below come directly from the retrieved primary sources and are presented at the level of detail those sources support.

Rabih Elawar follow-up (2026) ^[1]

The paper tracks Elawar’s recall at age sixty against the original Stevenson case record. The text notes that his past-life memory centers on emotionally significant events and that patterns of recall closely parallel those of present-life episodic memory, including sensitivity to emotional valence. Individual claim items are scored in a numbered table within the paper; the retrieved excerpts show examples (e.g., claim S23 — collision with an oncoming truck — is marked “Incorrect, per Hisham and accident report”; claim S24 — location of impact at a curve — is marked “True”). The overall tally of correct, incorrect, and unconfirmed items is in the full paper rather than the retrieved excerpts.

Animal ADC study (2025) ^[2]

The timing difference — grief-related visits concentrated in the first week after death, visits for other purposes spread more broadly — is the paper’s primary quantitative finding ^[2]. The effect size (φ = 0.516) is described in the paper as “securely in the strong range” ^[2].

Angela Grubbs dream case (2024) ^[5]

None of the 37 items were demonstrably false ^[5]. Matlock treats this as meaningful given that the items were recorded before verification; the high proportion of unconfirmed (rather than falsified) claims is presented as consistent with genuine memory rather than confabulation.

NDE pilot study (2025) ^[4]

The study examines NDE experiencers who subsequently reported past-life memories. The paper notes that the sample skewed toward women, and cites an earlier finding (Greyson & Stevenson, 1980) that female NDErs reported non-earthly realms significantly more often than male NDErs (χ² = 7.58, df = 1, p < .05) as context for interpreting the demographic pattern ^[4]. The pilot’s own primary statistics are in portions of the paper not fully represented in the retrieved excerpts.

E.C. case (2024) ^[6]

The paper documents a series of past-life visions and impressions surfacing in middle adulthood in a subject identified as E.C. Many of E.C.’s apparent memories of one identified historical figure turned out to be verifiable against sources accessed after the memories were recorded ^[6]. Behavioral influences — including somatic symptoms such as phantom pains without identified medical cause — are discussed as potential implicit-memory effects.

“Astrid” case (2025) ^[3]

Matlock documents flashbacks and dreams of an apparent pre-Christian Norwegian life following an NDE. Many elements of the reported memories are described as historically accurate or plausible and consistent with archaeological evidence and ancient sagas, though a previous-personality identification has not been established ^[3], ^[4].

Skeptical critiques

The sources retrieved for this question do not include published criticism directed specifically at Matlock’s studies. Several methodological limitations are, however, noted by Matlock himself across the retrieved papers.

In the NDE pilot study, he flags that the sample demographic (heavily female) may reflect sampling error rather than a genuine population difference ^[4]. In the Grubbs dream case, he acknowledges that the majority of the 37 items remain unconfirmed rather than verified, and that some conceivable items “seem odd” ^[5]. In the Astrid case, he states explicitly that a previous-personality identification has not been made and that no historical reference to the specific individual she describes has been found ^[3]. These are the authors’ own limitations, as recorded in the papers.

For the broader scholarly discussion of reincarnation case methodology — including questions about confirmation bias, documentation timing, and verification procedures — Matlock’s ESP-Nexus profile and its spoke page on past-life memory emergence and persistence carry additional context.
