RESUMEN

PURPOSE: To evaluate the neurophenomenology of automatic writing (AW) in a spontaneous automatic writer (NN) and four high hypnotizables (HH). METHODS: During fMRI, NN and the HH were cued to perform spontaneous (NN) or induced (HH) AW, and a comparison task of copying complex symbols, and to rate their experience of control and agency. RESULTS: Compared to copying, for all participants AW was associated with less sense of control and agency and decreased BOLD signal responses in brain regions implicated in the sense of agency (left premotor cortex and insula, right premotor cortex, and supplemental motor area), and increased BOLD signal responses in the left and right temporoparietal junctions and the occipital lobes. During AW, the HH differed from NN in widespread BOLD decreases across the brain and increases in frontal and parietal regions. CONCLUSIONS: Spontaneous and induced AW had similar effects on agency, but only partly overlapping effects on cortical activity.

RESUMEN

For many people worldwide, supernatural beliefs and attributions-those focused on God, the devil, demons, spirits, an afterlife, karma, or fate-are part of everyday life. Although not widely studied in clinical psychology, these beliefs and attributions are a key part of human diversity. This article provides a broad overview of research on supernatural beliefs and attributions with special attention to their psychological relevance: They can serve as coping resources, sources of distress, psychopathology signals, moral guides, and decision-making tools. Although supernatural attributions sometimes involve dramatic experiences seen to violate natural laws, people more commonly think of supernatural entities working indirectly through natural events. A whole host of factors can lead people to make supernatural attributions, including contextual factors, specific beliefs, psychopathology, cognitive styles and personality, and social and cultural influences. Our aim is to provide clinical psychologists with an entry point into this rich, fascinating, and often overlooked literature.

RESUMEN

Anomalous experiences (AE) (uncommon experiences or one that is believed to deviate from the usually accepted explanations of reality: hallucinations, synesthesia, experiences interpreted as telepathic…) and altered states of consciousness (ASC) have been described in all societies of all ages. Even so, scientists have long neglected the studies on this theme. To study AE and ASC is not necessary to share the beliefs we explore, they can be investigated as subjective experiences and correlated with other data, like any other human experience. This article presents some methodological guidelines to investigate these experiences, among them: to avoid dogmatic prejudice and to 'pathologize' the unusual; the value of a theory and a comprehensive literature review; to utilize a variety of criteria for pathology and normality; the investigation of clinical and non-clinical populations; development of new appropriate research instruments; to be careful to choose the wording to describe the AE; to distinguished the lived experience from its interpretations; to take into account the role of culture; to evaluate the validity and reliability of reports and, last but not least, creativity and diversity in choosing methods.

RESUMEN

This study aimed to explore the experiences, responses, and conceptualizations of sense of presence experiences in bereavement in terms of family meaning-making. A case study framework was chosen, using group and individual interviews and ethnographically derived observations in a father-bereaved family in the south of England. Interview data were analyzed by applying both phenomenological and social constructionist perspectives to the same data set. It was observed that there was a division between the mother, who had derived much personal benefit from sense of presence experiences, and the children, who dismissed the experiences as incompatible with their own worldviews and how they made sense of their father's death.

RESUMEN

INTRODUCTION: Depersonalisation and derealisation disorders refer to feelings of detachment and dissociation from one's "self" or surroundings. A reduced sense of self (or "presence") and emotional "numbness" is thought to be mediated by aberrant emotional processing due to biases in self-referent multi-sensory integration. This emotional "numbing" is often accompanied by suppressed autonomic arousal to emotionally salient stimuli. METHODS: 118 participants completed the Cambridge Depersonalisation scale [Sierra, & Berrios, 2000. The Cambridge Depersonalisation Scale: A new instrument for the measurement of depersonalisation. Psychiatry Research, 93, 153-164)] as an index of dissociative anomalous experience. Participants took part in a novel "Implied Body-Threat Illusion" task; a pantomimed injection procedure conducted directly onto their real body (hand). Objective psychophysiological data were recorded via standardised threat-related skin conductance responses and finger temperature measures. RESULTS: Individuals predisposed to depersonalisation/derealisation revealed suppressed skin conductance responses towards the pantomimed body-threat. Although the task revealed a reliable reduction in finger temperature as a fear response, this reduction was not reliably associated with measures of dissociative experience. CONCLUSIONS: The present findings significantly extend previous research by revealing emotional suppression via a more direct body-threat task, even for sub-clinical groups. The findings are discussed within probabilistic and predictive coding frameworks of multi-sensory integration underlying a coherent sense of self.

RESUMEN

Anomalous perceptual experiences in adolescents are common and may predict future psychotic disorders and other psychopathologies. However, the underlying structure and their specific relationships with bullying victimizations, a typical stressor for adolescents, remain unclear. Therefore, the current study aimed to clarify the structure of perceptual anomalies as assessed by the Cardiff Anomalous Perceptions Scale (CAPS) using exploratory graph analysis (EGA), a new factor retention method based on network psychometrics. The second aim was to explore whether specific dimensions of perceptual anomalies are particularly associated with certain forms of bullying victimization. Data from a validated sample of 1199 Chinese adolescents (56.0 % females, age range: 14-20) on perceptual anomalies and bullying victimizations were analyzed using network approaches, including EGA and mixed graphical modeling (mgm). Results showed that each anomalous perception was experienced by 13.8-50.3 % of the participants. EGA identified four dimensions: aberrant bodily perceptions, altered daily experiences, chemosensation (i.e., abnormal gustatory and olfactory experiences), and clinical psychosis (i.e., visual and auditory hallucinatory experiences). Among them, the altered daily experiences dimension possessed the highest centrality. Physical bullying and cyberbullying were directly and positively linked to two of the aberrant bodily experiences. Bootstrap analyses suggest that the results are reliable. The current findings support the existence of multiple contributive factors to perceptual anomalies and underscore the importance of bullying prevention in reducing mental health risks for adolescents, particularly the risk of psychosis.

RESUMEN

Introduction: Dissociative identity disorder, formerly called multiple personality disorder, is a rupture of identity characterized by the presence of two or more distinct personality states, described in some cultures as an experience of possession. Objective: The case of a 30-year-old woman with dissociative identity disorder and borderline personality disorder associated with a previous history of anomalous experience was reported. Case Report: A 30-year-old woman who fulfilled the DSM-5 criteria for dissociative identity disorder and borderline personality disorder reported the presence of unusual sensory experiences (clairvoyance, premonitory dreams, clairaudience) since she was 5 years old. The patient told that for 12 months she presented episodes in which a "second self" took charge of her actions: she would then speak with a male voice, become aggressive, and require several people to contain her desire for destruction. After 3 months of religious follow-up, and accepting her unusual experiences and trance possessions as normal and natural, she had significant improvement. Conclusion: When approaching DID and BPD patients, it is necessary to observe the anomalous phenomena (in the light of) closer to their cultural and religious contexts, to promote better results in the treatment of their disorders, which has not been explored in the treatment guide.

RESUMEN

The purpose of this study was to create a detailed characterization of the nature of the sensory perceptions associated with after-death communication. A primary aim was to determine if perceptions of after-death communication (ADC) support one or more of three hypotheses: (1) they are the result of hallucinations or day-to-day thoughts about the deceased; (2) they are subjective phenomena reflecting the extrasensory perception of remote events; or (3) they constitute objective phenomena, perceived more solidly, as if within the physical world. Methods: The study included a quantitative analysis and qualitative first-person narrative description of part of the data set from a detailed questionnaire study (991 viable cases) investigating the phenomenology of spontaneous ADCs. Results and Conclusions: A majority of respondents reported that ADCs were distinctly different from simple thoughts about the deceased. Specifically, relative distribution of ADCs across the senses was 46% visual, 44% auditory, 48% touch, and 28% olfactory, with 34% sensing the presence of the deceased without input from the five senses. ADCs often were perceived as external and having properties of the material world (e.g., solidity, tactile qualities). Even the more nebulous 'sense of presence' cases were perceived as having a distinct location in space and as being identifiable as a specific deceased presence despite the lack of sensory cues. These elements are more compatible with hypotheses 2 and 3 than hypothesis 1.
