Abstract:
Abstract In defence of naïve realism, Fish has advocated an eliminativist view of hallucination, according to which hallucinations lack visual phenomenology. Logue, and Dokic and Martin, respectively, have developed the eliminativist view in different manners. Logue claims that hallucination is a non-phenomenal, perceptual representational state. Dokic and Martin maintain that hallucinations consist in the confusion of monitoring mechanisms, which generates an affective feeling in the hallucinating subject. This paper aims to critically examine these views of hallucination. By doing so, I shall point out what theoretical requirements are imposed on naïve realists who characterize hallucinations as non-visual-sensory phenomena.

Abstract:
BackgroundIt has been proposed that the relationship between childhood trauma and hallucinations can be explained by dissociative processes. The present study examined whether the effect of childhood trauma on hallucination-proneness is mediated by dissociative tendencies. In addition, the influence of dissociative symptoms on a cognitive process believed to underlie hallucinatory experiences (i.e. reality discrimination; the capacity to discriminate between internal and external cognitive events) was also investigated.MethodPatients with schizophrenia spectrum disorders (n=45) and healthy controls (with no history of hallucinations;n=20) completed questionnaire measures of hallucination-proneness, dissociative tendencies and childhood trauma, as well as performing an auditory signal detection task.ResultsCompared to both healthy and non-hallucinating clinical controls, hallucinating patients reported both significantly higher dissociative tendencies and childhood sexual abuse. Dissociation positively mediated the effect of childhood trauma on hallucination-proneness. This mediational role was particularly robust for sexual abuse over other types of trauma. Signal detection abnormalities were evident in hallucinating patients and patients with a history of hallucinations, but were not associated with pathological dissociative symptoms.ConclusionsThese results are consistent with dissociative accounts of the trauma-hallucinations link. Dissociation, however, does not affect reality discrimination. Future research should examine whether other cognitive processes associated with both dissociative states and hallucinations (e.g. deficits in cognitive inhibition) may explain the relationship between dissociation and hallucinatory experiences.

Abstract:
Within philosophy, hallucinations have served as a paradigmatic test-case for epistemology in general and for theories of perception in particular. The differentiation of hallucinations from “real-life-perception” poses some interesting problems. Here, I will focus on two opposing views: first the view of hallucination as a failure of a metacognitive ability, and second a phenomenologically based view of hallucinations as a disturbance of experiential world-directedness.Our theoretical understanding of hallucinations however, should take the highly unsettling existential effects on the patients themselves into account as well. As one admits to have experienced a hallucination, this calls into question one's entire capability of perception in general. For how can one be sure not to be hallucinating again? The loss of a basic trust in one's own senses can be so stressful as to aggravate the existing symptoms. These existential effects show that perception cannot be taken as a singular faculty and strengthen the phenomenological approach to hallucinations.

Abstract:
BackgroundPrevious research has demonstrated that various types of verbal source memory error are associated with positive symptoms in patients with schizophrenia. Notably, intrusions in free recall have been associated with hallucinations and delusions. We tested the hypothesis that extra-list intrusions, assumed to arise from poor monitoring of internally generated words, are associated with verbal hallucinations and that intra-list intrusions are associated with global hallucination scores.MethodA sample of 41 patients with schizophrenia was administered four lists of words, followed by free recall. The number of correctly recalled words and the number of extra- and intra-list intrusions were tallied.ResultsThe verbal hallucination score was significantly correlated with the number of extra-list intrusions, whereas it was unrelated to the number of correctly recalled words. The number of intra-list intrusions was significantly correlated with the global, but not with the verbal, hallucination score in the subsample of hallucinating patients. It was marginally significantly correlated with the delusion score in delusional patients.ConclusionsThe data corroborate the view that verbal hallucinations are linked to defective monitoring of internal speech, and that errors in context processing are involved in hallucinations and delusions.

Abstract:
Regions of the brain involved in language and attention were studied using [18F]-fluorodeoxyglucose in PET. In nine chronic DSM–III schizophrenic patients who had persistent auditory hallucinations, ten who had recovered from hallucinations and ten normal controls. In none of the regions examined was metabolic activity significantly different in hallucinating patients compared with that in other groups. However, a pattern of seven significant correlations of metabolic activity between language regions and between frontal and parietal cortex characterised the hallucinating but not the other groups. Three of the seven correlations were significantly greater in hallucinating patients than in the two other groups, and six were greater in hallucinating patients than controls. Metabolism in Broca's region and its right-hemisphere homologue correlated positively and significantly in the hallucinating group, as it did in anterior cingulate and left superior temporal areas, and in right frontal and parietal areas. Hallucination ratings correlated with metabolism in the anterior cingulate region.

Abstract:
BackgroundThe pathophysiology of auditory verbal hallucinations remains poorly understood.AimsTo characterise the time course of regional brain activity leading to auditory verbal hallucinations.MethodDuring functional magnetic resonance imaging, 11 patients with schizophrenia or schizoaffective disorder signalled auditory verbal hallucination events by pressing a button. To control for effects of motor behaviour, regional activity associated with hallucination events was scaled against corresponding activity arising from random button-presses produced by 10 patients who did not experience hallucinations.ResultsImmediately prior to the hallucinations, motor-adjusted activity in the left inferior frontal gyrus was significantly greater than corresponding activity in the right inferior frontal gyrus. In contrast, motor-adjusted activity in a right posterior temporal region overshadowed corresponding activity in the left homologous temporal region. Robustly elevated motor-adjusted activity in the left temporal region associated with auditory verbal hallucinations was also detected, but only subsequent to hallucination events. At the earliest time shift studied, the correlation between left inferior frontal gyrus and right temporal activity was significantly higher for the hallucination group compared with non-hallucinating patients.ConclusionsFindings suggest that heightened functional coupling between the left inferior frontal gyrus and right temporal regions leads to coactivation in these speech processing regions that is hallucinogenic. Delayed left temporal activation may reflect impaired corollary discharge contributing to source misattribution of resulting verbal images.

Abstract:
AbstractStudy Objective(s)The pathogenesis of complex visual hallucination in patients without visual lesions, appearing with eyes open and resolving with eyes closed, has been described to be associated with increased excitation at the lateral geniculate nucleus (LGN) and pulvinar of the thalamus (Winton-Brown, 2016). This reduces thefidelity of retinogeniculate transmissions and enhances aberrant projections to the visual cortex. Loss of the central sensory filtering function of the pulvinar increases “signal to noise ratio” in visual transmission. While visual hallucinations have been reported to disappear on eye closure (Manford, 1998), visual aberration with correction with refractionfollowed by focusing on actual visual images and visual hallucinations has not heretofore been reported. Such a case is presented.MethodCase study: This 28-year-old, myopic, right-handed man, at 5 years of age began hallucinating vivid images of people. The visual hallucinations were triggered only with his eye open. He was myopic and without visual correction, his visual sphere would be blurred. The visual hallucinations were also blurred without visual correction. With refraction, the hallucinations became clearly in focus. He would close his eyes and the visual hallucinations disappeared but would reappear in the same position upon opening his eyes. For over 20 years, he experienced about 100 hallucinations a day. Electroencephalography (EEG) revealed continuous spikes and slow waves in bilateral temporal lobes, consistent with temporal lobe status epilepticus. After treatment with diphenylhydantoin the frequency and duration of the hallucinations markedly decreased to a second epoch every other day. However, the characteristic of the hallucinations remained the same (people).ResultsThis phenomenon may involve epilepsy induced excitation of the thalamus. This then acts to reduce the fidelity of retinogeniculate transmission and increase “signal to noise ratio” in visual transmission. This may contribute to complex visual hallucinations with eyes open. The hallucinated figures becoming clearer with eyeglasses provides support that this complex hallucination arises in the pathway from retina-LGN-cortex, not from stored visual associated cortex of top-down cortical release.ConclusionsGiven the above, those with visual hallucinations should be queried as to the influence of refraction on the clarity of hallucination.FundingNo funding.

Abstract:
In serving patients, especially patients with psychotic disorders, nurses are faced with situations where patients experience hallucinations. Severe hallucinatory behavior is sometimes easily assessed, but the symptoms of hallucinations are vague and mild, sometimes escape observation. Digital technology developed both audio and visual as well as Virtual Reality can quickly assess the appearance of hallucinatory symptoms, monitor hallucinatory behavior, thereby preventing hallucinations from becoming severe and preventing recurrence. Finally, the patient can get past the hallucinations that appear, and it is easy for the family to seek medical care as soon as possible if they know the behavior of the patient who is experiencing hallucinations early. This literature review aims to describe the development of digital technology in the assessment of hallucinations. This study uses a literature review method. The databases used are ScienceDirect, Scopus, Spingerlink and Oxford Journals. Articles with several keywords, such as hallucinations assessment, hallucinations, hallucinations assessment digital technology. The use of digital technology in assessing hallucinations can improve the quality of care. Further development in digital technology is needed to assess hallucinatory symptoms. Keywords : hallucination, “hallucination assessment”, “hallucination assessment digital technology”

Abstract:
Abstract Background and Hypothesis The social deafferentation hypothesis (SDA) has been proposed as an explanatory mechanism of hallucinations, based on the theory that social withdrawal triggers the initial phase of schizophrenia. The current study tests the SDA by assessing how loneliness is associated with different types of hallucinations. Under the SDA, increased loneliness is hypothesized to affect the occurrence of hallucinations that carry social meaning, but not of nonsocial hallucinations. Study Design As part of an online survey, 2038 adolescents and young adults from the general population (median age 21 years; 75% female) filled out the Questionnaire for Psychotic Experiences, and the shortened De Jong Gierveld Loneliness Scale. Binomial logistic regression was used to investigate the effects of loneliness severity on past month prevalence of hallucinations, and on the presence of social versus nonsocial hallucinations. Study Results Loneliness increased the prevalence of hallucinations across modalities in the past month. Moreover, stronger degree of loneliness increased the likelihood of hearing voices or laughter, and of hallucinating being touched. Conversely, loneliness decreased the likelihood of experiencing the nonsocial hallucination of a tingling feeling. As expected, loneliness did not increase the prevalence of experiencing nonsocial hallucinations. Surprisingly, neither was loneliness associated with experiencing felt presence. Conclusions Our results are novel in showing that loneliness specifically increases the likelihood of hearing human sounds such as voices or laughter, or feeling a human touch. Hallucinations without social meaning were not more likely to be experienced with increasing loneliness. This forms a confirmation of the SDA.

Abstract:
Background: Psychosis in bipolar disorder is common but still not well understood. There is paucity of literature from our country and none from this institute which serves the eastern part of Nepal.Objective: To describe the hallucinations and delusions in bipolar disorders in our place.Methods: Patients-record files of bipolar disorders with psychosis discharged in two years’ time from 2012 to 2014 were analysed. Patients with unipolar depression, recurrent depressive disorder, serious organic illness, and primary substance use disorders were excluded. Information was collected in a structured performa. Association of delusion and hallucination was observed.Results: During the study period, ninety-five patients with bipolardisorder had psychosis. Hallucination was present in 29 (30.5%) cases, and out of these 23 (79.3%) were cases of mania. In 26 (89.7%) patients, the hallucinations were mood congruent. The median duration of appearance of hallucination was 10 days and appeared early in mania. Among hallucinations, auditory verbal hallucinations were present in all 29 patients. Delusions were present in 77 (81.1%) of patients, and grandiose delusions were the most common. Grandiose delusions tended to occur even in the absence of hallucinations. Conclusion: Psychosis is common in bipolar disorder. Grandiose delusions are the most common delusion and are relatively independent of hallucination. The auditory verbal hallucinations are the most common type of hallucination. Hallucinations in mania tend to manifest earlier than in bipolar depression and mixed episode, and most of the hallucinations in bipolar disorder are mood congruent.

Abstract:
Introduction: Auditory hallucinations are a commonly experienced phenomenon. Theories have been devised in order to help explain how and why this phenomenon occurs, some attributing its occurrence to stressful life events, other explaining it as originating from misattributed thoughts. This study tested the relation between patients who experience auditory hallucinations and their pattern of metacognitions and thought strategies. Method: 12 participants suffering from auditory hallucinations from different parts of Norway were assessed by following instruments: categories of worry (AnTI), metacognitions (MCQ-30), strategies for thought control (TCQ), beliefs about auditory hallucinations (BAVQ-R) and metacognitions with regard to auditory hallucinations (MCQ-VH). Results: Results revealed that participants scored high on positive and negative meta-beliefs in regard to auditory hallucinations. There was further an association between measure of meta-worry as indicated by AnTI and interpretation of voices as indicated by BAVQ-R Earlier research on coping with voices had proposed that distraction was used by voice hearers who cope poorly. Correlational analyses found no relation between beliefs about malevolence and omnipotence of voices and distraction, although participants used distraction as a thought control strategy in order to cope with their voices. Conclusion: This study indicates that metacognitions might be an important factor in perpetuating auditory hallucinations and the discomfort this experience entails. The theoretical and clinical implications of these findings are discussed.

Abstract:
Notre thèse défend l’idée d’une primauté de l’hallucination sur la perception. En effet, nous verrons, chez Freud et chez Lacan, la structure d’illusion d’une réalité fondée sur un temps inaugural qui est celui de l’hallucination. Ceci nous permettra d’envisager les moments de « vacillements de la perception », autrement dit, l’hallucination en dehors du champ de la psychose. Dans un second temps, nous aborderons l’hallucination psychotique à partir des différentes conceptions psychiatriques, de l’apport de Merleau-Ponty, puis de Freud, avant de voir la critique radicale adressée par Lacan à partir du modèle de l’hallucination verbale. Dans un troisième temps, nous verrons l’intérêt d’une approche différentielle de l’hallucination psychotique – , hallucination visuelle, hallucination corporelle – qui permet de questionner l’hypothèse de l’hallucination verbale en tant que phénomène inaugural. A partir de la clinique de la schizophrénie, nous ferons l’hypothèse de la schize en tant que phénomène hallucinatoire premier, à partir duquel émergent les voix, comme tentative d’interprétation
Our thesis defends the idea of a primacy of hallucination on perception. Indeed we will study first, in Freud and Lacan, the hallucination structure of a reality based on an inaugural time which is the time of hallucination. This will allow us to view the « perception failings moments », that is to say, the hallucination out of psychosis field.Then, we will tackle psychotic hallucination of different psychiatric conceptions, from Merleau-Ponty to Freud. We will finish with the radical critic, expressed by Lacan, from the model of verbal hallucination. In a third time, we will see the interest of a differential approach of the psychotic hallucination : the verbal, visual and corporal ones. This differential approach allows us to question the verbal hallucination hypothesis as an inaugural phenomenon. From the schizophrenic clinic, we will make the hypothesis that the « schize » is an inaugural hallucinatory phenomenon from which emerge voices as a interpretation attempt

Abstract:
Le relationnalisme affirme que le caractère phénoménal de la perception est en partie constitué par les objets que l’on voit. Malgré son attrait intuitif, il est souvent rejeté en vertu de l'argument de l'hallucination. L'objectif de cette thèse est de défendre le relationnalisme. L'argument fait valoir que, puisque le relationnalisme ne peut être vrai pour les hallucinations, il doit forcément être faux pour les perceptions aussi. En cela, l'argument repose sur le principe de l’indiscernabilité (IND), affirmant que deux expériences qui sont introspectivement indiscernables les unes des autres ont le même caractère phénoménal. Je considère et rejette les autres versions de l'argument qui ne reposent pas sur l'IND. Bien que largement accepté, aucun support satisfaisant pour l'IND n'a encore été présenté. Dans cette thèse, je soutiens que la défense de l'IND requiert que l’on entende la notion d’indiscernabilité employée dans l'IND en un sens impersonnel. Ensuite, j’identifie ce qui motive l'IND : l'intuition que, en vertu de sa superficialité, la nature d'un caractère phénoménal doit être accessible par l'introspection, de concert avec l’idée qu’il est impossible de nier l'IND sans nier par là même la superficialité des caractères phénoménaux.Je soutiens que le relationnaliste peut nier l'IND tout en préservant la superficialité des caractères phénoménaux en adoptant une thèse négative de l'hallucination et en reconsidérant la nature de la relation entre le caractère phénoménal d’une expérience et l’accès introspectif qu'il peut y avoir
Relationalism claims that the phenomenal character of perception is constituted by the obtaining of a non-representational psychological relation to mind-independent objects. Although relationalism provides what seems to be the most straight forward and intuitive account of how experience strikes us introspectively, it is very often believed that the argument from hallucination shows that the view is untenable. The aim of this thesis is to defend relationalism against the argument from hallucination. The argument claims that the phenomenal character of hallucination and perception deserves the same account, and that relationalism cannot be true for hallucinations, therefore relationalism must be rejected. This argument relies on the Indistinguishability Principle (IND), the claim that two experiences that are introspectively indistinguishable from each other have the same phenomenal character. Before assessing the plausibility of this principle, I first consider and dismiss versions of the argument which wouldn’t depend on IND.Although widely accepted, no satisfactory support for IND has been presented yet. In this thesis I argue that defending IND requires that we understand the notion of ‘indiscriminability’ employed in IND in an impersonal sense. I then identify what underwrites IND: the intuition that, in virtue of its superficiality, the nature of a phenomenal character must be accessible through introspection, together with the claim that it is not possible to deny IND without denying the superficiality of phenomenal characters too.I argue that the relationalist can deny IND while preserving the superficiality of phenomenal characters. This can be done by adopting a negative view of hallucination and an account of introspection whereby the phenomenal character doesn’t exist independently of one’s introspective awareness of it and where having introspective access to our experience depends on our perceptual access to the world

Abstract:
The Psychological Flexibility Model describes a process-oriented approach to behaviour change that underpins Acceptance and Commitment Therapy (ACT), a contextual cognitive behavioural intervention. ACT promotes psychological flexibility, which refers to a person’s ability to connect with the present moment fully as a conscious human being (mindfulness and non-judgemental acceptance), and to change or persist with behaviour that is in line with identified values. For people distressed and/or disabled by auditory hallucinations, it is theorised that this experience is responded to in a psychologically inflexible manner: becoming a target for avoidance, control or focus, appraised as more powerful than the person experiencing the voices, and leading to actions that come at the cost of engaging in chosen life directions. Previous research on coping, cognitive models and mindfulness interventions for voice hearing point to the possibility that promoting active acceptance and changing the relationship with voices may be associated with better outcomes. This thesis investigates the role of psychological flexibility with voice hearing using correlational, single-case and experimental research designs. The first study in this thesis investigated the relationship of psychological flexibility and mindfulness with distress, disability, and behavioural responses to voice hearing, using self-report questionnaires in a sample of 50 distressed voice hearers. The findings suggest that psychological flexibility and non-judgemental acceptance, over and above appraisals of voices and thought control strategies, is related to voice hearers’ levels of general depressive and anxiety symptoms, and behavioural resistance to voices, but not to engagement with voices, voice-related distress or life disruption. The second study reports the findings of a 10-session ACT intervention for eight distressed voice hearers using multi-baseline single case design, assessing whether outcome changes following ACT are concomitant with increasing psychological flexibility. Following ACT there were group-level improvements in depressive symptoms, quality of life and social functioning, with changes in psychological flexibility (non-judgemental acceptance, independent action from voices). The third study involved 110 non-clinical participants experiencing simulated auditory hallucinations in an experimental analogue, and investigated differences in response following training in a regulation strategy (acceptance, reappraisal or suppression). This study did not show any significant differences between groups; the potential explanations for this lack of expected difference include the features of simulated voices, sample characteristics, and participants’ degree of adherence to the coping strategy. The findings of these studies are considered within the broader context of emotional wellbeing with voice hearing, functional approaches to understanding responding to voices, and potential implications for clinical and research directions.

Abstract:
Background: Musical hallucination (AM) is a type of complex auditory hallucination described as hearing musical tones, rhythms, harmonies, and melodies without the corresponding external auditory stimulus. This type of hallucination is relatively rare and is seen less often than other types of hallucination. Such hallucinations can be continuous or intermittent and are usually accompanied by a clear and critical awareness on the part of the patient. AM are found mainly in elderly women with progressive hearing loss, usually due to ear diseases or lesions. They also occur in neurological disorders, neuropsychological disorders (eg dementia) and psychiatric disorders, especially depression. Objective: To evaluate clinical and neuropsychological issues of the elderly with Musical Hallucinations Methods: Twenty-seven outpatient patients clinic of Geriatrics and Gerontology at FMJ from January 2010 to October 2019 were selected Results: Of the 27 patients, 20 were women. The average age was 83.47 years. The most prevalent diseases were systemic arterial hypertension, osteoporosis, diabetes mellitus, hypothyroidism, osteoporosis, chronic obstructive pulmonary disease and dementia syndrome. With the exception of one patient, all had hearing loss. The songs were the most varied from Gregorian chant to lullaby. Many had this picture for months and continuously (day and night). 40% of them had no insight into AM. We emphasize that all these patients sought medical care with the main complaint of musical hallucination. Conclusion: In general, AM has an uninterrupted, fragmentary and repetitive character. They are involuntary, intrusive and have an apparent exteriority. They differ from the simple mental image of auditory sensation in that they appear to come from outside the individual as if they actually hear an external device playing music. Currently, it is estimated that about 2% of elderly people with hearing loss also have AM. The neuropsychological basis of AM is not fully established. The phenomenological study, especially the perception of complex sequences and consistency with previous auditory experience strongly suggest the involvement of central auditory processing mechanisms. Normal musical auditory processing involves several interrelated brain levels and subsystems. While the recognition of elementary sounds is done in the primary auditory cortex, the recognition of musical characteristics such as notes, melody and metric rhythm occur in a secondary and tertiary association center, which in turn, are greatly influenced by regions linked to memory and emotion.

Abstract:
Despite their impressive generative capabilities, LLMs are hindered by fact-conflicting hallucinations in real-world applications. The accurate identification of hallucinations in texts generated by LLMs, especially in complex inferential scenarios, is a relatively unexplored area. To address this gap, we present FactCHD, a dedicated benchmark designed for the detection of fact-conflicting hallucinations from LLMs. FactCHD features a diverse dataset that spans various factuality patterns, including vanilla, multi-hop, comparison, and set operation. A distinctive element of FactCHD is its integration of fact-based evidence chains, significantly enhancing the depth of evaluating the detectors' explanations. Experiments on different LLMs expose the shortcomings of current approaches in detecting factual errors accurately. Furthermore, we introduce TRUTH-TRIANGULATOR which synthesizes reflective considerations by tool-enhanced ChatGPT and LoRA-tuning based on Llama2, aiming to yield more credible detection through the amalgamation of predictive results and evidence.

Abstract:
Background: Charles Bonnet syndrome (CBS) is defined by repetitive experiences of visual hallucinations. This classically affects the elderly with visual impairment, intact cognition and the absence of psychiatric illness. Hallucinations remain indefinitely and can be static, dynamic, elementary or complex, colored or in black and white, centrally or peripherally. Objectives: To analyze the scientific information available on the clinical aspects of CBS. Methods: A bibliographic review was carried out in the PubMed database, in the last 10 years, using the descriptors “Charles Bonnet Syndrome”, “Hallucinations” and “Prognosis”, associated with the Boolean operator “AND’’. English and Portuguese were included, inconclusive studies were excluded, with biases or duplicates, whose approaches did not indicate an outcome in the syndrome, selecting 12 articles. Results: It was observed that there is no consensus on the pathophysiology and age range of CBS involvement, which varies between 70 and 80. The incidence is up to 1.4%. As for the prognosis, one of the articles pointed to the presence of hallucinations between 7 and 18 months, these varying in complexity, frequency and impact on patients’ lives. Diagnosis is made by exclusion, emphasizing the benign character, assertive diagnosis and effective treatment are essential factors for the mild evolution of the disorder. Conclusion: As it is considered a rare disease, it is rarely addressed in the literature and, therefore, new studies are desirable, in order to demystify the condition and ensure an appropriate approach to patients.
