This page documents the revision history of the abstract submitted for the Regional Sleep Medicine Symposium (2010) and the associated working papers from the longitudinal sleep recall study. Four drafts were produced between 2009 and 2010. The submitted version is draft 04.

This revision history is maintained in the departmental archive for internal reference. The withdrawn 2012 abstract (draft 05) is included below. It was not submitted for publication. Its removal from the active submission pipeline was confirmed by the department chair, February 2012.

[Title] Consistent Shared Site Recall in Sleep Disorder Patients: Preliminary Observations from a Longitudinal Study
[Abstract] A longitudinal study of subjective sleep recall in patients with chronic sleep disorders has identified a statistically anomalous pattern of consistent shared site recall across unrelated participants. Forty-seven enrolled patients, participating in monitored overnight sessions, independently described a consistent spatial environment without prompting or cross-participant contact. Initial findings suggest this pattern strengthens over the course of extended participation.
[Methods] Participants completed standardized spatial recall inventories following each monitored session. No environmental prompts or imagery were provided. Recall forms were reviewed by the principal investigator only. Cross-participant consistency was assessed via blind coding of spatial descriptors.
[Results — preliminary] Of 47 participants, 31 produced spatial recall descriptions containing at least two consistent environmental features. Eleven participants independently described features consistent at the level of specific architectural detail. Three participants independently described the same indexed location within the spatial environment. This level of consistency is not attributable to chance or shared pre-study experience.

Draft 02 — January 2010

Key substitutions from Draft 01 to Draft 02
[Title — removed] Consistent Shared Site Recall in Sleep Disorder Patients [Title — replaced] Environmental Recall Consistency in Chronic Sleep Disorder Patients
[Abstract — removed] "consistent shared site recall" [Abstract — replaced] "environmental recall consistency"
[Results — removed] "the same indexed location within the spatial environment" [Results — replaced] "a high degree of spatial recall overlap"
[Results — removed] "This level of consistency is not attributable to chance or shared pre-study experience." [Results — replaced] "Further longitudinal observation is indicated."

Reviewer note (Jan 2010, unsigned): "The framing in draft 01 is not appropriate for a clinical venue. Revise to describe the observation without asserting its mechanism."

Draft 03 — February 2010

Minor editorial corrections to draft 02. No structural changes. Submitted to symposium committee February 18, 2010.

[Title] Environmental Recurrence in Sleep-Disorder Populations: Notes Toward a Longitudinal Assessment Framework
[Abstract] Over the course of a five-year longitudinal study, 47 patients with chronic sleep disorders independently described a consistent spatial environment under monitored conditions. Descriptions produced without prompting by unrelated participants converged on specific architectural features, directional orientations, and discrete locations. The spatial environment described shows internal consistency sufficient to permit mapping. The study data indicate this environment is not a product of shared cultural imagery or experimental priming. It preceded the study. The study did not create it. This abstract proposes a preliminary framework for classifying spatial recurrence of this type and describes the assessment instruments developed during the study period.
[Methods] As described in Vale & Ellison (2011). Extended observation windows applied from session 18 onward per protocol amendment EC-004 (March 2012). Cross-participant comparison conducted on session 18+ data only. Spatial descriptor coding performed blind by two independent reviewers.
[Results] Convergence rate at session 18 or later: 71% of active participants (n=33). Of these, 24 produced descriptions consistent at the level of specific named or numbered features. A subset of 5 participants (n=5) produced descriptions consistent at the level of sequential event recall — describing events in the spatial environment that correlated with events described by other participants in sessions conducted on different dates. The mechanism for this correlation is not established. The observation is noted.
[Conclusion] The data collected under Protocol 7A (WU-CBN-2007-044) indicate an anomalous and reproducible pattern of spatial recall convergence that warrants dedicated investigation. The author acknowledges that the framing of this abstract is not standard for a clinical venue. The author has concluded that standard framing is not adequate for this observation.
