    Haunted People Syndrome Redux: Concurrent Validity From an Independent Case Study

    by Ciarán O’kEeffe, Brandon Massullo, Brian Laythe, Neil Dagnall, Ken Drinkwater, James Houran

    Auerbach et al. (2023) proposed an AECKO model to describe the features and dynamics of a poltergeist-like disturbance they investigated with virtual technology during the COVID-19 pandemic. A two-part exercise nonetheless shows that their findings fundamentally support Laythe, Houran, Dagnall et al.’s (2021) grounded theory of Haunted People Syndrome (HP-S), which was independently developed at an earlier time. HP-S asserts that ghostly episodes recurrently manifesting to certain people are an interactionist phenomenon emerging from individuals with heightened somatic-sensory sensitivities, which are stirred by dis-ease states, contextualized with paranormal belief, and reinforced via perceptual contagion and threat-agency detection. Part 1 of our research identified strong conceptual parallels between the AECKO and HP-S models, whereas Part 2 involved a content analysis by an independent and clinically-trained researcher (with cross-checking by an expert panel) who used standardized measures to compare Auerbach et al.’s case to the phenomenology of ‘spontaneous’ ghostly episodes and the five recognition patterns of HP-S. The available data suggested this case had below-average ‘haunt intensity’ that closely approximated baseline scores for Illicit and Fantasy narratives. Likewise, its S/O distribution pattern most resembled accounts with knowingly embellished or false testimony. These results imply that the anomalies considered here were not expressly ‘spontaneous.’ Content analysis further detected a majority of the HP-S recognition patterns in the case material, as well as evidence that the apparent focus person strongly matched the psychometric profile of poltergeist agents found in prior research. Auerbach et al.’s data, therefore, arguably provide good concurrent validity for the HP-S model. Taken altogether, we assert that ghostly episodes are best conceptualized, researched, and addressed through a biopsychosocial lens and phenomenological approach, irrespective of the potential contribution of putative psi. We discuss these ideas relative to new research directions and clinical applications.

    Structural Relationships Among Mental Boundaries, Childhood Imaginary Companions, Creative Experiences, and Entity Encounters

    by Kenneth Drinkwater, Neil Dagnall, James Houran, Andrew Denovan, Ciarán O’kEeffe

    This study investigated relationships between thin mental boundary functioning, creativity, imaginary companions (ICs), and anomalous ‘(entity) encounter experiences.’ A convenience sample of 389 respondents completed the Revised Transliminality Scale, Oxford-Liverpool Inventory of Feelings and Experiences, Creative Experiences Questionnaire, Survey of Strange Events, and a measure of Childhood Imaginary Companions. Competing testing with path analysis found that the best-fitting model was consistent with the causal chain of ‘Thin Boundaries (transliminality and schizotypy) → Creative Experiences → ICs → (Entity) Encounter Experiences.’ These results suggest that deep-types of ICs (i.e., showing apparent independent agency) are perhaps most accurately characterized as syncretic cognitions versus hallucination-like experiences. The authors examine these findings relative to study limitations, as well as discussing the need for future research that approaches ICs as a special mental state that can facilitate allied altered-anomalous experiences. In this context, this study furthered understanding of relationships between conscious states related to mental boundaries, childhood imaginary companions, creative experiences, and entity encounters.


  • Haunted people syndrome revisited: empirical parallels between subjective paranormal episodes and group-stalking accounts

    by Rense Lange, James Houran, Lorraine Sheridan, Neil Dagnall, Kenneth Drinkwater, Ciaran O'KEeffe, Brian Laythe

    Research suggests a Haunted People Syndrome (HP-S) is defined by the recurrent perception of anomalous subjective and objective events. Occurrences are traditionally attributed to supernatural agencies, but we argue that such interpretations have morphed into themes of “surveillance and stalking” in group-stalking reports. We tested a series of related hypotheses by re-analyzing survey data from the 2015 Sheridan and James study to explore statistical patterns in “delusional” group-stalking accounts (N=128) versus“non-delusional” (control) accounts of lone-culprit stalking (N=128). As expected, we found that (i) account types had different Rasch hierachies, (ii) the Rasch hierarchy of group-stalking experiences showed a robust unidimensional model, and (iii) this group-stalking hierarchy correlated significantly with spontanous “ghost“ experiences. However, we found no clear evidence for “event clustering” that might signify contagious processes in symptom perception. Findings support the viability of the HP-S construct and the idea that experiences of group-stalking and haunts share common sources.

    Things That Go Bump in the Literature: An Environmental Appraisal of “Haunted Houses”

    by Neil Dagnall, Kenneth G. Drinkwater, Ciarán O’kEeffe, Annalisa Ventola, Brian Laythe, Michael A. Jawer, Brandon Massullo, Giovanni B. Caputo, James Houran

    This paper contains a narrative overview of the past 20-years of environmental research on anomalous experiences attributed to “haunted house.” This exercise served as a much-needed update to an anthology of noteworthy overviews on ghosts, haunts, and poltergeists (Houran and Lange, 2001b). We also considered whether new studies had incorporated certain recommendations made in this anthology. Our search revealed a relative paucity of studies (n = 66) on environmental factors that ostensibly stimulate haunt-type experiences. This literature was diverse and often lacked methodological consistency and adherence to the prior suggestions. However, critical consideration of the content revealed a recurring focus on six ambient variables: embedded (static) cues, lighting levels, air quality, temperature, infrasound, and electromagnetic fields. Their relation to the onset or structure of witness reports showed mostly null, though sometimes inconsistent or weak outcomes. However, such research as related to haunts is arguably in its infancy and new designs are needed to account better for environmental and architectural phenomenology. Future studies should therefore address four areas: (i) more consistent and precise measurements of discrete ambient variables; (ii) the potential role of “Gestalt influences” that involve holistic environment-person interactions; (iii) individual differences in attentional or perceptual sensitivities of percipients to environmental variables; and (iv) the role of attitudinal and normative influences in the interpretation of environmental stimuli. Focused scrutiny on these issues should clarify the explanatory power of evolutionary-environmental models for these and related anomalous experiences.


  • The Dr. John Hall story: a case study in putative “Haunted People Syndrome”

    by Ciaran O'KEeffe, James Houran, Damien J. Houran, Neil Dagnall, Kenneth Drinkwater, Lorraine Sheridan, Brian Laythe

    Research suggests a “Haunted People Syndrome (HP-S)” defined by recurrent and systematic perceptions of anomalous subjective and objective anomalies. Such signs or symptoms are traditionally attributed to “spirits and the supernatural,” but these themes are hypothesised to morph to “surveillance and stalking” in reports of “group-(or gang) stalking,” We tested this premise with a quali-quantitative exercise that mapped group-stalking experiences from a published first-hand account to a Rasch measure of haunt-type anomalies. This comparison found significant agreement in the specific “signs or symptoms” of both phenomena. Meta-patterns likewise showed clear conceptual similarities between the phenomenology of haunts and group-stalking. Findings are consistent with the idea that both anomalous episodes involve the same, or similar, attentional or perceptual processes and thereby support the viability of the HP-S construct.

    Escaping Plato’s Cave: Ethical considerations for the use of Virtual Reality in psychology teaching

    by Kristin P.J. Thompson, Ciarán O’kEeffe, Genevieve M. Cseh, Piers Worth, Matthew D. Smith, Ciarn Okeeffe

    Author Summary: Virtual Reality (VR) offers exciting new opportunities for teaching psychology, such as the chance to explore questions, phenomena, perspectives and experiences it would be difficult or impossible to observe in the real world or classroom. As VR technology develops, its potential to provide a multi-modal sensory experience may lead to even more immersive environments. With these exciting opportunities, however, come new ethical dilemmas and risks for teachers and students utilising this technology. Many users and manufacturers of VR acknowledge the physiological and psychological impacts of the use of VR (e.g. Sharples, Cobb, Moody, & Wilson, 2008). One of the most commonly reported effects is motion-sickness, however, improvements in technology may help to lessen these. An increasing number of studies are now revealing potential psychological impacts, for example, Aim, Cotton, and Bouchard (2009) found females reporting increased body dissatisfaction after immersive VR use, and Aardema, OConnor, Ct and Taillon (2010) found users reporting greater sense of dissociation and lower sense of presence in objective reality. As yet, however, the British Psychological Society (BPS), the professional body for the discipline of psychology, has provided no specific ethical guidelines for the use of VR or Augmented Reality (AR) in research with human participants or in an educational setting.Our behaviour is influenced by our environment and VR can place students in highly unusual, disorientating environments which can at times create sensations akin to experiences with hallucinogens; these impacts should not be taken lightly, even within informal teaching settings. We aim to address this need within psychology research and teaching, by discussing some potential risks and ethical considerations for educators wishing to use VR in educational settings, including: cybersickness, consensual hallucinations; pressure to conform and power of authority, individual differences in response to VR, and the need for pre and post-use care. Some practical recommendations are presented which also encompass our findings that some pre-use screening tools are insufficient to capture a participant’s actual experience and, in some individuals, can prematurely discourage VR usage when in actuality their experience is unexpectedly positive. How could they see anything but the shadows if they were never allowed to move their heads?Plato The Allegory of the Cave The Republic (Book VII)

  • Attitudes towards offenders with mental health problems scale

    by Anna Louise Glendinning, Ciaran O'KEeffe

    Purpose: – The purpose of this paper is to suggest that there was a need for a psychometric measure to assess attitudes specifically towards offenders with mental health problems. The “Community Attitudes towards the Mentally Ill” scale (CAMI; Taylor and Dear, 1981) was adapted to create a new psychometric measure; the “Police and Community Attitudes towards Offenders with Mental Illness” scale (PACAMI-O).Design/methodology/approach: – A sample of police and community participants (n=178) completed this scale through the online surveying system, Psychdata. The new psychometric measure utilised the same 40 items featured in the CAMI; although, the wording was adapted.Findings: – The internal reliability for the combined sample was high (α=0.929), which implied very good internal reliability. An exploratory factor analysis identified four new factors: Self-Preservation, Societal Reservation, Mental Health Awareness and Treatment Ideology. At-test revealed there was a significant difference between the scores of the police and community sample, with the effect size depicting a large magnitude between the means (t(176)=p=0.019,η2=0.16).Practical implications: – The PACAMI-O scale appears adequate for measuring attitudes towards its targeted sample and has shown utility with; a professional group (police officers and custody sergeants) who potentially face such offenders (primarily in the context of using Section 136 of the Mental Health Act). It therefore has practical implications in assessing attitudes with other groups within forensic mental health.Originality/value: – Assessing attitudes towards offenders with mental health problems would enable a better understanding of the formation of negative attitudes and stigmatisation and therefore, ways of tackling treatment, rehabilitation and also community reintegration.
