Temporal lobe signs and reports of subjective paranormal experiences in a normal population: a replication

Correlations (r = 0.50) were found between the numbers of different psi (paranormal) experiences and the numbers of temporal lobe signs within a population of university students (n = 99). The strongest correlation of 0.60 occurred with a cluster of signs that are similar to symptoms reported by patients who show chronic foci in the mesiobasal temporal lobe. However, there were no significant correlations between numbers of different psi experiences and clusters of control items or a lie scale. Specific analyses of the 140 items of the inventory indicated only 23 reached statistical criterion (p less than .001). Of these 17 were direct temporal lobe signs that implied deepened affect, auditory-vestibular experiences (vibrations, hearing one's name called), olfactory auras, perseveration ("forced" thinking), depersonalization, and sense of the personal. Five items involved beliefs about exotic phenomena or philosophical ideas. Only one item was from a control cluster. These results support the hypothesis that mystical or paranormal experiences are associated with transient electrical foci within the temporal lobe of the human brain. The repeated occurrence of these experiences within normal individuals may be embedded within a more complex symptomatology of temporal lobe signs.     

Temporal lobe signs: electroencephalographic validity and enhanced scores in special populations

Internal and external validity tests were completed for an inventory that has been used to infer signs of temporal lobe lability. Strong, positive correlations were reported for a normal (reference) population between the numbers of responses that referred to paranormal experiences (including feelings of a "presence") and separately to religious beliefs and the numbers of spikes per minute within electroencephalographic recordings from the temporal lobe. Numbers of spikes were also correlated with the subjects' scores on the hysteria, schizophrenia, and psychasthenia scales from the MMPI. These clusters of items were not correlated with electrical activity from the occipital lobe (the comparison region). Numbers of responses to control clusters of mundane experiences were not correlated with the temporal lobe measures. A group of student poets scored higher on different subclusters of temporal lobe signs and on the schizophrenia and mania scales of the MMPI than the reference group. For both groups, there were positive correlations between the amount of alpha activity in the temporal lobe only and answers to items such as "hearing inner voices" and "feeling as if things were not real." These results demonstrate that quantitative measures of electrical changes in the temporal lobe are correlated with (or with the report of) specific experiences that are prevalent during surgical or epileptic stimulation of this brain region.     

Near-death experiences and the temporal lobe

Abstract— Many studies in humans suggest that altered temporal lobe functioning, especially functioning in the right temporal lobe, is involved in mystical and religious experiences. We investigated temporal lobe functioning in individuals who reported having transcendental "near-death experiences" during life-threatening events. These individuals were found to have more temporal lobe epileptiform electroencephalographic activity than control subjects and also reported significantly more temporal lobe epileptic symptoms. Contrary to predictions, epileptiform activity was nearly completely lateralized to the left hemisphere. The near-death experience was not associated with dysfunctional stress reactions such as dissociation, posttraumatic stress disorder, and substance abuse, but rather was associated with positive coping styles. Additional analyses revealed that near-death experiencers had altered sleep patterns, specifically, a shorter duration of sleep and delayed REM sleep relative to the control group. These results suggest that altered temporal lobe functioning may be involved in the near-death experience and that individuals who have had such experiences are physiologically distinct from the general population.     

A preliminary investigation of family coping styles and psychological well-being among adolescent survivors of Hurricane Katrina.

The relation between family coping styles and psychological well-being was compared for adolescents (12-17 years) displaced by Hurricane Katrina and currently living in a relocation camp (n = 50) and nonaffected adolescents (n = 31) matched on age, race, and socioeconomic status. Adolescents in the Katrina sample reported a family mobilizing strategy that reflected an increased reliance and seeking of extra-familial, community-based support but lower self-esteem and more symptoms of distress and depression. Follow-up analyses suggested that the relations between group differences in participants' hurricane-related trauma experiences and greater psychological distress may be mediated in part by the family coping strategy; exposure to increased levels of community-provided support may have unintended consequences on adolescents' psychological health. These results highlight the importance of future research on both potential benefits and costs of family coping styles in adolescents affected by a large-scale disaster.     

Paranormal beliefs and religiosity: Chinese version of the Revised Paranormal Belief Scale

This paper reports an initial study investigating the relations of paranormal beliefs with religiosity in a Chinese sample, as well as the development of a Chinese version of the Revised Paranormal Belief Scale and a test of its psychometric properties with 310 college students (5.5% Christians, 21.3% Buddhists, 61% believers in traditional Chinese religions, and 12% atheists). The reliability and validity of the Chinese version were satisfactory. In general, traditional Chinese religious believers had higher scores on paranormal belief than did Christians and atheists, and the mean total score of the Chinese participants was higher than previously reported in a Western sample. It was concluded that the greater involvement of practitioners of traditional Chinese religions in activities emphasizing paranormal experiences might contribute to their greater paranormal belief, especially as compared to the minority Christian group. The results are consistent with the idea that Christianity may offer the least support for paranormal belief.     

Haunted by somatic tendencies: Spirit infestation as psychogenic illness

It has been suggested that haunting and poltergeist episodes are akin to outbreaks of contagious psychogenic illness. Therefore, it might be expected that hypochondriacal and somatic tendencies would significantly predict self-reported experiences of 'spirit infestation' and other paranormal ideations. This prediction was tested on a sample of 314 undergraduate students who completed the Anomalous Experiences Inventory, the Transliminality Scale and three standard questionnaires about hypochondriasis, somatic complaints, and cognitions about body and health. Results from correlational and regression analyses supported predictions, although we found that the type of bodily cognition varied with the specificity of the paranormal experience. For example, indices of spirit infestation coincided with autonomic sensations, perceived paranormal ability was related to catastrophizing cognitions, and general paranormal experiences correlated with somatization traits. Transliminality and paranormal belief contributed positively to nearly all of these associations. These findings are consistent with the idea that some paranormal experiences are partly misattributions of internal experience to external (paranormal) sources - a process that could initiate an episode of contagious (mass) psychogenic illness by encouraging the collective perception of similar 'symptoms' in a group of people due to suggestion and demand characteristics.     

Temporal lobe epileptic signs and correlative behaviors displayed by normal populations

With regard to epileptic signs and correlative behaviors, one hypothesis is that the experiences and nonconvulsive behaviors of patients with electrical foci within the temporal lobe are also displayed, but with less intensity, by normal people. If this is correct, then there should be quantitative relationships between the numbers of major complex partial epileptic signs (CPES) and the occurrence of other frequent clinical experiences and behaviors. An inventory to answer this question was developed. Over a 3-year period, 414 (6 groups) university students were administered an inventory that included themes of CPES as well as control and information items. Strong correlations were consistently found between CPES scores and reports of paranormal (mystical, with religious overtones) experiences and "a sense of presence." Results from three personality (CPI, MMPI, and IPAT anxiety) inventories clearly demonstrated similar profiles. In addition to being more anxious, people who displayed higher CPES scores were more suspicious, aloof, stereotyped in their behavior, ruminative (overthinking), intellectually inefficient, and overly judgmental. CPES scores were significantly (p less than .001) correlated with the schizophrenia and mania subscales of the MMPI. The results suggest that functional hyperconnectionism of cortical-limbic systems within the brain may be more prevalent in the normal population than previously suspected.     

Disruption of spelling-to-sound correspondence mapping during single-word reading in patients with temporal lobe epilepsy

Processing and/or hemispheric differences in the neural bases of word recognition were examined in patients with long-standing, medically-intractable epilepsy localized to the left (N=18) or right (N=7) temporal lobe. Participants were asked to read words that varied in the frequency of their spelling-to-sound correspondences. For the right temporal lobe group, reaction times (RTs) showed the same pattern across spelling-to-sound correspondence conditions as previously reported for normal participants. For the left temporal lobe group, however, the pattern of RTs suggested a greater relative influence of orthographic frequency than rime frequency, such that performance was worse on words whose orthographic body was less frequent in the language. We discuss these results in terms of differences in processing between the two cerebral hemispheres: the results for the right-temporal lobe patients are taken to support connectionist models of reading as described for the dominant (left) hemisphere, while results for the left-temporal lobe patients support a view of the right hemisphere as relatively less sensitive to phonology and relatively more sensitive to orthography.     

Conceptions about the mind-body problem and their relations to afterlife beliefs,paranormal beliefs,religiosity, and ontological confusions

We examined lay people’s conceptions about the relationship between mind and body and their correlates. In Study 1, a web survey (N = 850) of reflective dualistic, emergentistic, and monistic perceptions of the mind-body relationship, afterlife beliefs (i.e., common sense dualism), religiosity, paranormal beliefs, and ontological confusions about physical, biological, and psychological phenomena was conducted. In Study 2 (N = 73), we examined implicit ontological confusions and their relations to afterlife beliefs, paranormal beliefs, and religiosity. Correlation and regression analyses showed that reflective dualism, afterlife beliefs, paranormal beliefs, and religiosity were strongly and positively related and that reflective dualism and afterlife beliefs mediated the relationship between ontological confusions and religious and paranormal beliefs. The results elucidate the contention that dualism is a manifestation of universal cognitive processes related to intuitions about physical, biological, and psychological phenomena by showing that especially individuals who confuse the distinctive attributes of these phenomena tend to set the mind apart from the body.     

Temporal lobe lability in the highly transliminal mind

Transliminality is “a hypothesized tendency for psychological material to cross thresholds into or out of consciousness,” which has been proposed to derive from hyperconnectivity between temporal-limbic structures and sensory association cortices. Accordingly, it might be expected that transliminality would positively correlate with temporal lobe lability. To test this hypothesis, 135 undergraduate psychology students at an Australian and a British university completed the Revised Transliminality Scale (Lange et al., 2000) and the Personal Philosophy Inventory (Persinger, 1984a), a validated measure of temporal lobe lability. As predicted, scores on transliminality showed a strong association with the general temporal lobe scale (r=0.72), as well as moderate correlations with a number of other scalar variables and individual items. The findings are consistent with the idea that transliminality is related to more ungated processing related to temporal lobe functioning, and furthermore that temporal lobe phenomenology promotes transliminal experiences with mystical or religious overtones.     

Critical thinking ability and belief in the paranormal

A study was conducted to assess the relationship between critical thinking and belief in the paranormal. 180 students from three departments (psychology, arts, computer science) completed one measure of reasoning, the Paranormal Belief Scale (Tobacyk & Milford, 1983), and a scale of paranormal experiences. Half of the subjects filled out the Cornell Critical Thinking Test (Ennis & Millmann, 1985) and the Watson–Glaser Critical Thinking Appraisal (Watson & Glaser, 2002), respectively. The results show no significant correlations between critical thinking and paranormal belief or experiences. Reasoning ability, however, had a significant effect on paranormal belief scores, but not on paranormal experiences. Subjects with lower reasoning ability scored higher on Traditional Paranormal Belief and New Age Philosophy than did subjects with higher reasoning abilities. Results suggest that those who have better reasoning abilities scrutinise to a greater extent whether their experiences are sufficient justification for belief in the reality of these phenomena.     

Geophysical variables and behavior: LV. Predicting the details of visitor experiences and the personality of experients: the temporal lobe factor

The visitor experience, a more intense form of the normal sense of presence, emphasizes the deep belief of personal contact with an extraterrestrial (or religious) entity. Phenomenological details of visitor experiences are expected to reflect the functions of deep temporal lobe structures; common details involve cosmic meaningfulness, vestibular experiences, flickering, complex visual sensations and alimentary references. After intense experiences, interictal-like behaviors similar to religious conversions (widening affect, sense of personal, desire to spread the word, concern about Man's destiny) emerge. Normal people who are prone to these experiences show frequent temporal lobe signs and specific personality characteristics that include enhanced creativity, suggestibility, mild hypomania, anxiety, and emotional lability. Learning histories that encourage the use of right temporal lobe functions for the consolidation of memory, such as compartmentalization of beliefs or repression due to early sexual abuse, predispose to intense visitor experiences. The most frequent precipitants are psychological depression, personal (existential) stress and proximal exposure to the focal tectonic strain fields that accompany luminous phenomena. Possible neuropsychological mechanisms are discussed.     

Temporal lobe signs and personality characteristics

Mature university students (14 men and 16 women) were asked to complete the 16 PF and a scale that samples temporal lobe signs in the normal population. People who reported frequent temporal lobe experiences were more emotionally unstable, impulsive, emotionally sensitive (imaginative inner self, actions based upon intuition and self-anxiety), and tense (free-floating anxiety). The results were compatible with personality characteristics of people who report "temporal lobe experiences" and have been assessed by the Minnesota Multiphasic Personality Inventory and the California Personality Inventory.     

Validation of the Narrative Emplotment Scale and its correlations with well‐being and psychological adjustment

Two studies examined correlates of the Narrative Emplotment Scale (NES), which measures the extent to which individuals perceive chance events and unchosen experiences as meaningfully connected. In Study 1 (N=99), the NES demonstrated adequate test–retest stability and good internal reliability. The scale was positively related to paranormal beliefs, mystical experiences, and absorption. In Study 2 (N=342), personality measures indicative of external locus of control, intrinsic religiosity, well‐being, satisfaction with life, and a measure of frequency of coincidence experience were all positively correlated with narrative emplotment, providing further support for the construct validity of the scale. In terms of the question of whether meaning making is predictive of better or worse psychological adjustment, analyses indicated that the relationship between narrative emplotment and psychological adjustment was moderated by individual differences in coping strategies. Path analysis indicated that emplotment was a mediator of the pathway between religiosity and well‐being. Emplotment had a negative effect on well‐being through chance locus of control. These analyses suggest that this type of meaning‐making is an important variable for understanding religious/spiritual beliefs and their influence on psychological adjustment.     

Psychological trauma associated with AIDS and HIV infection in women

The growing numbers of women faced with HIV infection and AIDS has specific counselling implications. This paper analyses the psychological needs of all women patients seen by the psychology department (n = 33) over the past 12 months. The mean age was 32.3 years. Psychological crisis was high. Four women reported rapes (three accounting for their HIV infection). Two women had suicide attempts (one on two occasions), Death experiences were notable, including multiple bereavement. Conjidentiality was problematic for many of the women. Problems were reported around pre- and post-test counselling which was absent for three women, and often surrounded the diagnosis of a loved one (child, husband or partner). Most women were first seen as in-patients (when disease progression was extensive) or when their partners or children were in-patients. Despite offers of out-patients follow-up, only four HIV + ve women attended, three of which were irregular. A group of ten women were only seen indirectly when provision of care wasgiven to their children. A consistent group were seen with worries about HIV (either due to sexual contact with a known HZV+ ve or at risk individual) or to unfounded concerns often reflecting underlying psychological problems. This paper explores the counselling challenges of AIDS and HIV for women.     

Panic-Related fears in persons reporting a family history of panic disorder

Abstract We administered the Body Sensations Questionnaire, Health Hardiness Index, Panic Attack Questionnaire, and the Symptom Checklist 90-R to college students (n=71) who either reported or did not report a family history of panic disorder. Participants who reported a family history of panic disorder reported significantly less perceived control over their health status, a greater fear of bodily arousal, and greater frequency of unexpected panic attacks compared to participants without such a history, although no significant group differences were detected for Symptom Checklist-90-R scales that measure negative emotional experiences. After controlling for personal history of panic, differences between the positive family history group remained only for the control over health measure. We discuss the results as preliminary evidence that certain cognitive responses are overrepresented in self-classified first-degree relatives of persons with panic disorder.     

SUPPORT FOR A NEUROPSYCHOLOGICAL MODEL OF SPIRITUALITY IN PERSONS WITH TRAUMATIC BRAIN INJURY

Recent research suggests that spiritual experiences are related to increased physiological activity of the frontal and temporal lobes and decreased activity of the right parietal lobe. The current study determined if similar relationships exist between self‐reported spirituality and neuropsychological abilities associated with those cerebral structures for persons with traumatic brain injury (TBI). Participants included 26 adults with TBI referred for neuropsychological assessment. Measures included the Core Index of Spirituality (INSPIRIT); neuropsychological indices of cerebral structures: temporal lobes (Wechsler Memory Scale‐III), right parietal lobe (Judgment of Line Orientation), and frontal lobes (Trail Making Test, Controlled Oral Word Association Test). As hypothesized, spirituality was significantly negatively correlated with a measure of right parietal lobe functioning and positively correlated (nonsignificantly) with measures of left temporal lobe functioning. Contrary to hypotheses, correlations between spirituality and measures of frontal lobe functioning were zero or negative (and nonsignificant). The data support a neuropsychological model that proposes that spiritual experiences are related to decreased activity of the right parietal lobe, which may be associated with decreased awareness of the self (transcendence) and increased activity of the left temporal lobe, which may be associated with the experience of specific religious archetypes (religious figures and symbols).     

Masculinity,Femininity, and Reported Paranormal Beliefs

Previous research has found that women are more likely than men to report belief in nonmaterial paranormal phenomena (e.g., psychics). There are inconsistent findings about whether men are more likely than women to report belief in material paranormal phenomena (e.g., bigfoot/sasquatch), and no prior survey research has examined gender expression (as masculine or feminine) as it relates to paranormal beliefs. This paper asks: How do gender identity and gender expression relate to reported paranormal beliefs? It answers this question using a large sample (n = 2504) of Canadians. Femininity helps explain differences between cisgender women and men on reported beliefs about foreseeing the future and telekinesis, but less so about reported belief in ghosts. Intriguingly, reported gender atypicality is associated with reported belief in all paranormal phenomena among cisgender women and among cisgender men. The results highlight the importance of measuring gender expression for beliefs that science cannot verify.     

Atrophy of the parietal lobe in preclinical dementia

Cortical grey matter atrophy patterns have been reported in healthy ageing and Alzheimer disease (AD), but less consistently in the parietal regions of the brain. We investigated cortical grey matter volume patterns in parietal areas. The grey matter of the somatosensory cortex, superior and inferior parietal lobule was measured in 75 older adults (38 cognitively stable and 37 individuals with cognitive decline after 3 years). Dementia screening 6 years after scanning resulted in nine AD cases from the cognitively stable (n=3) and cognitive decline group (n=6), who were assigned to a third group, the preclinical AD group. When regional differences in cortical volume in the parietal lobe areas were compared between groups, significant differences were found between either the cognitive decline or stable group on the one hand and preclinical AD individuals on the other hand in the inferior parietal lobule. Group membership was best predicted by the grey matter volume of the inferior parietal lobule, compared to the other parietal lobe areas. The parietal lobe was characterised by a differential atrophy pattern based on cognitive status, which is in agreement with the 'last-developed-first-atrophied' principle. Future studies should investigate the surplus value of the inferior parietal lobe as a potential marker for the diagnosis of AD compared to other brain regions, such as the medial temporal lobe and the prefrontal lobe.
