Auditory Verbal Experience and Agency in Waking,Sleep Onset,REM, and Non‐REM Sleep

We present one of the first quantitative studies on auditory verbal experiences (“hearing voices”) and auditory verbal agency (inner speech, and specifically “talking to (imaginary) voices or characters”) in healthy participants across states of consciousness. Tools of quantitative linguistic analysis were used to measure participants’ implicit knowledge of auditory verbal experiences (VE) and auditory verbal agencies (VA), displayed in mentation reports from four different states. Analysis was conducted on a total of 569 mentation reports from rapid eye movement (REM) sleep, non‐REM sleep, sleep onset, and waking. Physiology was controlled with the nightcap sleep–wake mentation monitoring system. Sleep‐onset hallucinations, traditionally at the focus of scientific attention on auditory verbal hallucinations, showed the lowest degree of VE and VA, whereas REM sleep showed the highest degrees. Degrees of different linguistic‐pragmatic aspects of VE and VA likewise depend on the physiological states. The quantity and pragmatics of VE and VA are a function of the physiologically distinct state of consciousness in which they are conceived.     

Paranoid delusions and threatening hallucinations: a prospective study of sleep paralysis experiences

Previously we reported a three-factor structure for hallucinations accompanying sleep paralysis (SP). These earlier analyses were, however, based on retrospective accounts. In a prospective study, 383 individuals reported individual episodes online providing further evidence for the three-factor structure as well as clearer conceptually meaningful relations among factors than retrospective studies. In addition, reports of individual episodes permitted a more fine-grained analysis of the internal structure of factors to assess predictions based on the hypothesis that a sensed or felt presence (FP) is a core experience affecting other SP hallucinations. Results were generally consistent with this hypothesis. In particular, associations among, and temporal stability of, sensory hallucinations were largely explained by their common association with FP. The findings are consistent with REM initiation of a threat activated vigilance system with pervasive effects on the SP experience and suggest a potential model for the thematic organization of nightmares and dreams more generally.     

Hallucinations and REM sleep behaviour disorder in Parkinson's disease: dream imagery intrusions and other hypotheses

REM sleep behaviour disorder (RBD) is a REM sleep-related parasomnia which may be considered a “dissociated state of wakefulness and sleep”, given that conflicting elements of REM sleep (dreaming) and of wakefulness (sustained muscle tone and movements) coexist during the episodes, leading to motor and behavioural manifestations reminiscent of an enacted dream. RBD has been reported in association with α-synucleinopathies: around a third of patients with Parkinson’s disease (PD) have full-blown RBD.Recent data indicate that PD patients with RBD are more prone to hallucinations than PD patients without this parasomnia. However it is still not clear why RBD in PD is associated with an increased prevalence of VHs.Data exist which suggest that visual hallucinations in PD may be the result of untimely intrusions of REM visual imagery into wakefulness. RBD, which is characterised by a REM sleep dissociation pattern, might be a condition that particularly favours such intrusions. However, other hypotheses may be advanced. In fact, deficits in attentional, executive, visuoperceptual and visuospatial abilities have been documented in RBD and found to occur far more frequently in PD with RBD than in PD without RBD. Neuropsychological deficits involving visual perception and attentional processes are thought to play an important role in the pathophysiology of VHs. On this basis, RBD in PD could be viewed as a contributory risk factor for VHs.     

REM motivation induced by brief REM deprivation: the influence of cognition, gender, and personality.

Prominence of the brain's right-hemisphere information processing and intensity of dream experience are two theoretically related constructs that have been proposed as important psychological aspects of REM sleep. Either view is consistent with the prediction that the effect of REM deprivation will depend in part on the nature of cognitive activity that is initiated at the onset of each REM period and that "substitutes" for the interrupted REM process. In the present study, the effect of REM deprivation was more striking for female subjects given a digits task than for female subjects given a fantasy-reporting task during awakening used to induce REM deprivation for the first 6 hours of the night. High neuroticism appeared to exaggerate the effect. No corresponding pattern was observed for the male subjects. These preliminary finding may be exaggerated by cognitive activity that is functionally incongruent with those processes. The results also raise interesting questions about individual differences.     

Dissociations of the night: individual differences in sleep-related experiences and their relation to dissociation and schizotypy.

The author examined the associations among sleep-related experiences (e.g., hypnagogic hallucinations, nightmares, waking dreams, and lucid dreams), dissociation, schizotypy, and the Big Five personality traits in 2 large student samples. Confirmatory factor analyses indicated that (a) dissociation and schizotypy are strongly correlated-yet distinguishable-constructs, and (b) the differentiation between them can be enhanced by eliminating detachment/depersonalization items from the dissociation scales. A general measure of sleep experiences was substantially correlated with both schizotypy and dissociation (especially the latter) and more weakly related to the Big Five. In contrast, an index of lucid dreaming was weakly related to all of these other scales. These results suggest that measures of dissociation, schizotypy, and sleep-related experiences all define a common domain characterized by unusual cognitions and perceptions.     

Mundane hallucinations and new wave relationalism

Relationalism maintains that mind-independent objects are essential constituents of veridical perceptual experiences. According to the argument from hallucination, relationalism is undermined by perfect hallucinations, experiences that are introspectively indistinguishable from veridical perceptual experiences but lack an object. Recently, a new wave of relationalists have responded by questioning whether perfect hallucinations are possible: what seem to be perfect hallucinations may really be something else, such as illusions, veridical experiences of non-obvious objects, or experiences that are not genuinely possible. This paper argues that however well new wave relationalism may handle brains in vats, drug users “seeing” pink elephants, and other extraordinary hallucinations, it struggles to accommodate mundane hallucinations, such as “hearing” your child cry out from the room down the hall when she is actually sound asleep or “feeling” vibrations on your thigh even when your phone isn't in your pocket. Mundane hallucinations are best explained as byproducts of noise in the perceptual system, and noise-induced hallucinations are resistant to the strategies that new wave relationalists deploy to explain away other hallucinations. Mundane hallucinations can thus underpin an especially powerful version of the argument from hallucination.     

Delusions and delusional reasoning

In 2 studies, delusional participants assigned higher probabilities to narratives of actual delusions than participants with no history of delusions; previously delusional participants did not differ significantly from delusional participants or participants with no history of delusions. In Study 2, the authors found that this reasoning bias was specific to delusions and did not generalize to "neutral" text. Familiarity with the content of the delusion narratives played a mediating role in the estimation of their probability, but delusional status also had a significant, independent effect. These findings are consistent with the Bayesian model of delusion formation proposed by D. R. Hemsley and P. A. Garety (1986), and with R. P. Bentall, P. Kinderman, and S. Kaney's (1994) concept of "emotional saliency." A productive area of future research might be to further determine the elements of "emotional saliency" and their impact on the individual steps of the Bayesian model.     

Reactions to bullying and peer victimization: Narratives,physiological arousal,and personality

A mediational model of bullying and victimization is proposed and tested. Ninety-nine 10- to 13-year-old children provided two oral narratives of their victimization experiences, as perpetrator and victim, with their physiological arousal being measured while they told the narratives. The children and one of their parents also completed a variety of questionnaires, including a Big 5 measure of personality and measures of bullying and victimization tendencies. Mediational analyses indicated that children who score low on Conscientiousness and high on Neuroticism are more likely to experience negative affect during peer conflict, such as feeling angrier, blaming the bully more, and forgiving less, and that these reactions are related to higher levels of victimization. For bullies, relations among Agreeableness, Conscientiousness, and bullying appear to be mediated by lesser feelings of guilt and gains in physiological arousal while telling a bullying narrative. Advantages of a mediational model of peer victimization processes and implications for interventions are discussed.     

Men Play,Women Break the Town: Gender and Intergenerational Asymmetry in Sexual and Reproductive Worldview Among the Ga of Ghana

A contemporary critique levelled against sexual and reproductive (SR) behavioral studies in Africa is the dominance of Western theories and perspectives, with the main language through which SR categories and concepts are developed and investigated being Western or colonial, which rarely correspond with local and ethnic conceptualizations. In this paper, we conduct an ethnolinguistic analysis of gender and intergenerational constructions of sexual and reproductive behaviors (SRB) among the Ga of Ghana. Ethnographic approaches were used to collect and analyze two data sources from seventy-two respondents; first, a lexicon of common words, phrases, terminologies and coinages on SR activities and relationships. Second, narratives on respondents’ major SR experiences, through a biography of respondents’ body methodological framework. Respondents reflected a high degree of conceptual baggage, underpinned by their own gendered SR experiences, in their selection and interpretation of the terminologies/words. Younger respondents were more likely to use flippant coinages for risky SRB, which resonate with their narratives on their casual and unrestrained SR behaviours. We discuss the SR health threats and opportunities of our findings.     

Factor analyses of the DIB-R in adolescents

The goal of this study was to examine the factor structure of the Revised Diagnostic Interview for Borderlines (DIB-R; Zanarini, Gunderson, Franckenburg, & Chauncey, 1989) in a nonpatient sample of 118 adolescents. A principal components factor analysis with a Varimax rotation extracted three factors. A confirmatory factor analysis showed that this three-factor model provided an adequate fit. The first factor, which included depression, anxiety, helplessness/hopelessness, loneliness/emptiness, and also encompassed odd thinking/unusual perceptive experiences and quasi-psychotic experiences, appeared to be centered on painful feelings and dissociative defense. The second factor, labeled "impulsivity," consisted of impulse action patterns, counterdependency, and stormy relationships. This factor seemed to be centered on defensive acting-out. The third factor, called "aggressiveness," consisted of anger, hypomania, devaluation/manipulation/sadism, and demand/entitlement, and might express manic/narcissistic defenses. These analyses suggest that there may be homogeneous components of borderline symptomatology in adolescents that may reflect affective disturbances and defensive mechanisms.     

Autoscopic phenomena and one's own body representation in dreams

Autoscopic phenomena (AP) are complex experiences that include the visual illusory reduplication of one’s own body. From a phenomenological point of view, we can distinguish three conditions: autoscopic hallucinations, heautoscopy, and out-of-body experiences. The dysfunctional pattern involves multisensory disintegration of personal and extrapersonal space perception. The etiology, generally either neurological or psychiatric, is different. Also, the hallucination of Self and own body image is present during dreams and differs according to sleep stage. Specifically, the representation of the Self in REM dreams is frequently similar to the perception of Self in wakefulness, whereas in NREM dreams, a greater polymorphism of Self and own body representation is observed. The parallels between autoscopic phenomena in pathological cases and the Self-hallucination in dreams will be discussed to further the understanding of the particular states of self awareness, especially the complex integration of different memory sources in Self and body representation.     

The Puzzle of Metacoherence

I develop a view of the common factor between subjectively indistinguishable perceptions and hallucinations that avoids analyzing experiences as involving awareness relations to abstract entities, sense‐data, or any other peculiar entities. The main thesis is that hallucinating subjects employ concepts (or analogous nonconceptual structures), namely the very same concepts that in a subjectively indistinguishable perception are employed as a consequence of being related to external, mind‐independent objects or property‐instances. These concepts and nonconceptual structures are identified with modes of presentation types. Since a hallucinating subject is not related to any such objects or property‐instances, the concepts she employs remain empty. I argue that the phenomenology of hallucinations and perceptions can be identified with employing concepts and analogous nonconceptual structures. By doing so, I defend an ontologically minimalist view of the phenomenology of experience that (1) vindicates Aristotelianism about types and (2) amounts to a naturalized view of the phenomenology of experience.     

Experiencing versus contemplating: Language use during descriptions of awe and wonder

Awe and wonder are theorised to be distinct from other positive emotions, such as happiness. Yet little empirical or theoretical work has focused on these emotions. This investigation explored differences in language used to describe experiences of awe and wonder. Such analyses can provide insight into how people conceptualise these emotional experiences, and whether they conceptualise these emotions to be distinct from other positive emotions, and each other. Participants wrote narratives about experiences of awe, wonder and happiness. There were differences in the language used to describe these positive emotional states, consistent with the theorised functions of each emotion. Awe was related to observing the world, reflected in greater use of perception words. Wonder was related to trying to understand the world, reflected in greater use of cognitive complexity and tentative words. Language use for both emotions reflected an environmental focus, whereas language use for happiness reflected a social/relationship focus.     

50 Voices of Disbelief: Why We Are Atheists. Edited by Russell Blackford and Udo Schüklenk

This article presents a narrative analysis of 18 Muslims' prayer experiences. The results of the study showed that experiences of answered prayers are structured by collective narratives and refer to other texts in the religious tradition. The narratives have important social and individualizing functions that help them remain Muslims in modern society. The informants reported that they had experienced situations when they had prayed but did not receive what they requested. They did not, however, mediate any well-formed narratives about these experiences, primarily because of a lack of collective narratives structuring the event in this way. The analysis showed, furthermore, that the informants used four strategies in order to transform the experience of unanswered prayers into answered prayers. The analysis concludes that prayer experiences are fluid phenomena "located" in the interplay between individual, text, and context.     

Brain-mind states: reciprocal variation in thoughts and hallucinations

The exclusion of thinking from recent studies of sleep mentation has hindered a full appreciation of how cognitive activity differs across the states of waking and sleep. To overcome this limitation, this study investigated thoughts and hallucinations using experience sampling, home-based sleep-wake monitoring, and formal analyses of the psychological data. The prevalence of thoughts decreased gradually from waking through sleep onset and non-REM sleep, to reach its nadir in REM sleep, whereas hallucinations increased sharply across these states. Furthermore, multiple occurrences of hallucinations but not of thoughts increased significantly from sleep onset through non-REM sleep, to a peak in REM sleep. This reciprocity in thoughts and hallucinations might reflect a progressive shift from high to low aminergic-to-cholinergic neuromodulatory ratios across wake-sleep states, accompanied by an array of changes in the regional activation patterns of the brain.     

Analysis of the multidimensionality of hallucination-like experiences in clinical and nonclinical Spanish samples and their relation to clinical symptoms: implications for the model of continuity

Numerous studies have found that hallucinatory experiences occur in the general population. But to date, few studies have been conducted to compare clinical and nonclinical groups across a broad array of clinical symptoms that may co-occur with hallucinations. Likewise, hallucination-like experiences are measured as a multidimensional construct, with clinical and subclinical components related to vivid daydreams, intrusive thoughts, perceptual disturbance, and clinical hallucinatory experiences. Nevertheless, these individual subcomponents have not been examined across a broad spectrum of clinically disordered and nonclinical groups. The goal of the present study was to analyze the differences and similarities in the distribution of responses to hallucination-like experience in clinical and nonclinical populations and to determine the relation of these hallucination-like experiences with various clinical symptoms. These groups included patients with schizophrenia, non-psychotic clinically disordered patients, and a group of individuals with no psychiatric diagnoses. The results revealed that hallucination-like experiences are related to various clinical symptoms across diverse groups of individuals. Regression analysis found that the Psychoticism dimension of the Symptom Check List (SCL-90-R) was the most important predictor of hallucination-like experiences. Additionally, increased auditory and visual hallucination was the only subcomponent that differentiated schizophrenic patients from other groups. This distribution of responses in the dimensions of hallucination-like experiences suggests that not all the dimensions are characteristic of people hearing voices. Vivid daydreams, intrusive thoughts, and auditory distortions and visual perceptual distortions may represent a state of general vulnerability that does not denote a specific risk for clinical hallucinations. Overall, these results support the notion that hallucination-like experiences are closer to a quasi-continuum approach and that total scores on these scales explain a state of vulnerability to general perceptual disturbance.     

A three-factor model of trait anger: dimensions of affect, behavior, and cognition

The structure of trait anger was tested in a study of 24 self-report scales. Exploratory factor analyses in an undergraduate sample (N = 457) yielded a two-factor model (comprising cynicism and aggression) and a three-factor model (representing angry emotions, aggressive behaviors, and cynicism). Subsequent evaluations, including confirmatory factor analyses, indicated that the three-factor model provided the best characterization of the trait anger domain. The three-factor solution was consistent with an "ABC" conceptualization of trait anger, consisting of the dimensions of affect, behavior, and cognition. The three factors showed strikingly different associations with the Big Five personality traits. Angry Affect was most strongly related to Neuroticism, whereas Behavioral Aggression was associated with low Agreeableness. Cynical Cognition represented a blend of neurotic and disagreeable characteristics. Modest mean-level differences were observed between the genders for each factor.     

Suicide and prostitution among street youth: a qualitative analysis

This study presents the results of a qualitative analysis of the narratives of 29 street youth in which they describe their experiences with, and understanding of, suicide. A history of attempted suicide was reported by 76% of the participants and the analysis revealed themes of isolation, rejection/betrayal, lack of control, and most centrally, low self-worth as forming the basis of their experiences concerning suicide. Additionally it was found that trading sex, in which most participants had been or were currently involved, was linked with their suicidal experiences and may account for the high attempt rate. Finally, variables related to suicide were found that have not been examined previously in the literature on street youth, including loss of control, assault during prostituted sex, drug abuse as a "slow suicide," and breakups in intimate relationships.     

The Limbic System and the Soul: Evolution and the Neuroanatomy of Religious Experience

The evolutionary neurological foundations of religious experience are detailed. Human beings have been burying and preparing their dead for the Hereafter for more than 100,000 years. These behaviors and beliefs are related to activation of the amygdala, hippocampus, and temporal lobe, which are responsible for religious, spiritual, and mystical trancelike states, dreaming, astral projection, near-death and out-of-body experiences, and the hallucination of ghosts, demons, angels, and gods. Abraham, Moses, Muhammad, and Jesus Christ, and others who have communed with angels or gods display limbic system hyperactivity, whereas patients report religious hallucinations or out-of-body experiences when limbic structures are stimulated or excessively activated. It is postulated that limbic and temporal lobe structures account for the sexual and violent aspects of religious behavior and also serve as a "transmitter to God," and that the evolution of these structures made spiritual experience possible.
