RESUMEN

Ketamine treatment has shown promising effects for different mental disorders. Yet, little is known on how people who receive ketamine for a psychiatric problem subjectively experience undergoing this intervention. We conducted a systematic literature search to identify relevant qualitative research on the first-person experience of undergoing ketamine treatment in a psychiatric context. 24 eligible studies were identified and analysed using a thematic meta-synthesis approach. Three main themes were identified. First, 'The Ketamine treatment experience can be understood as a three-stage journey with unique clinical features at each stage'. Second, 'The subjective experience of acute ketamine treatment is multifaceted and complex'. Third, 'Ketamine treatment can have different positive effects-but what happens if it does not work?'. In summary, the subjective experience of receiving ketamine treatment for a psychiatric problem can be understood as a journey whereby patients move towards, then undergo, and eventually depart from ketamine. Before treatment, the experiential focus lies on expectations, hopes, and feelings towards the drug. During treatment, the drug's multifaceted psychotropic effects and how they are emotionally appraised become central to experience. Once treatment is finished, the focus is on the presence or absence of clinically relevant effects. The conceptual framework we propose can guide further qualitative research on this topic and aid mental health professionals to better understand the experience of patients who undergo ketamine treatment for a psychiatric problem.

RESUMEN

BACKGROUND: The rise of a new generation of intelligent neuroprostheses, brain-computer interfaces (BCI) and adaptive closed-loop brain stimulation devices hastens the clinical deployment of neurotechnologies to treat neurological and neuropsychiatric disorders. However, it remains unclear how these nascent technologies may impact the subjective experience of their users. To inform this debate, it is crucial to have a solid understanding how more established current technologies already affect their users. In recent years, researchers have used qualitative research methods to explore the subjective experience of individuals who become users of clinical neurotechnology. Yet, a synthesis of these more recent findings focusing on qualitative methods is still lacking. METHODS: To address this gap in the literature, we systematically searched five databases for original research articles that investigated subjective experiences of persons using or receiving neuroprosthetics, BCIs or neuromodulation with qualitative interviews and raised normative questions. RESULTS: 36 research articles were included and analysed using qualitative content analysis. Our findings synthesise the current scientific literature and reveal a pronounced focus on usability and other technical aspects of user experience. In parallel, they highlight a relative neglect of considerations regarding agency, self-perception, personal identity and subjective experience. CONCLUSIONS: Our synthesis of the existing qualitative literature on clinical neurotechnology highlights the need to expand the current methodological focus as to investigate also non-technical aspects of user experience. Given the critical role considerations of agency, self-perception and personal identity play in assessing the ethical and legal significance of these technologies, our findings reveal a critical gap in the existing literature. This review provides a comprehensive synthesis of the current qualitative research landscape on neurotechnology and the limitations thereof. These findings can inform researchers on how to study the subjective experience of neurotechnology users more holistically and build patient-centred neurotechnology.

RESUMEN

Autonoetic consciousness is the awareness that an event we remember is one that we ourselves experienced. It is a defining feature of our subjective experience of remembering and imagining future events. Given its subjective nature, there is ongoing debate about how to measure it. Our goal was to develop a framework to identify cognitive markers of autonoetic consciousness. Across two studies (N = 342) we asked young, healthy participants to provide written descriptions of two autobiographical memories, two plausible future events, and an experimentally encoded video. Participants then rated their subjective experience during remembering and imagining. Exploratory Factor Analysis of this data uncovered the latent variables underlying autonoetic consciousness across these different events. In contrast to work that emphasizes the distinction between Remember and Know as being key to autonoetic consciousness, Re-experiencing, and Pre-experiencing for future events, were consistently identified as core markers of autonoetic consciousness. This was alongside Mental Time Travel in all types of memory events, but not for imagining the future. In addition, our factor analysis allows us to demonstrate directly - for the first time - the features of mental imagery associated with the sense of autonoetic consciousness in autobiographical memory; vivid, visual imagery from a first-person perspective. Finally, with regression analysis, the emergent factor structure of autonoetic consciousness was able to predict the richness of autobiographical memory texts, but not of episodic recall of the encoded video. This work provides a novel way to assess autonoetic consciousness, illustrates how autonoetic consciousness manifests differently in memory and imagination and defines the mental representations intrinsic to this process.

RESUMEN

BACKGROUND: Technology has significantly reshaped the landscape and accessibility of gambling, creating uncharted territory for researchers and policy makers involved in the responsible gambling (RG) agenda. Digital payment solutions (DPS) are the latest addition of technology-based services in gambling and are now prominently used for deposit and win withdrawal. The seamless collaboration between online gambling operators and DPS, however, has raised concerns regarding the potential role of DPS platforms in facilitating harmful behavior. OBJECTIVE: Using a focus group session with problem gamblers, this study describes a preliminary investigation of the role of DPS in the online gambling context and its influence on players' gambling habits, financial behavior, choices of gambling environment, and the overall outcome of gambling subjective experiences. METHODS: A total of 6 problem gamblers participated in a one-and-half-hour focus group session to discuss how DPSs are integrated into their everyday gambling habits, what motivates them to use DPS, and what shifts they observe in their gambling behavior. Thematic analysis was used to analyze the empirical evidence with a mix of inductive and deductive research approaches as a knowledge claim strategy. RESULTS: Our initial findings revealed that the influence of DPSs in online gambling is multifaced where, on the one hand, their ability to integrate with players' existing habits seamlessly underscores the facilitating role they play in potentially maximizing harm. On the other hand, we find preliminary evidence that DPSs can have a direct influence on gambling outcomes in both subtle and pervasive ways-nudging, institutionalizing, constraining, or triggering players' gambling activities. This study also highlights the increasingly interdisciplinary nature of online gambling, and it proposes a preliminary conceptual framework to illustrate the sociotechnical interplay between DPS and gambling habits that ultimately capture the outcome of gambling's subjective experience. CONCLUSIONS: Disguised as a passive payment enabler, the role of DPS has so far received scant attention; however, this exploratory qualitative study demonstrates that given the technological advantage and access to customer financial data, DPS can become a potent platform to enable and at times trigger harmful gambling. In addition, DPS's bird's-eye view of cross-operator gambling behavior can open up an opportunity for researchers and policy makers to explore harm reduction measures that can be implemented at the digital payment level for gambling customers. Finally, more interdisciplinary studies are needed to formulate the sociotechnical nature of online gambling and holistic harm minimization strategy.

RESUMEN

During psychiatric diagnostic interviews, the clinician's question usually targets specific symptom descriptions based on diagnostic categories for ICD-10/DSM-5 (2, 3). While some patients merely answer questions, others go beyond to describe their subjective experiences in a manner that highlights the intensity and urgency of those experiences. By adopting conversation analysis as a method, this study examines diagnostic interviews conducted in an outpatient clinic in South Finland and identifies sequences that divulge patients' subjective experiences. From 10 audio-recorded diagnostic interviews, 40 segments were selected where patients replied to medically or factually oriented questions with their self-disclosures. The research focus was on the clinicians' responses to these disclosures. We present five sequential trajectories that the clinicians offered third-position utterances in response to their patients' self-disclosure of subjective experiences. These trajectories include the following: 1) the clinician transfers the topic to a new agenda question concerning a medical or factual theme; 2) the clinician presents a follow-up question that selects a topic from the patient's self-disclosure of a subjective experience that may orient either towards the medical/factual side or the experiential side of the patient's telling; 3) the clinician provides an expert interpretation of the patient's self-disclosure of his or her subjective experience from the clinician's expert perspective; 4) the clinician gives advice that orients mainly to a treatment recommendation or to another activity; and 5) the clinician presents a formulation that focusses on the core of their patient's self-disclosure of his or her subjective experience from the patient's perspective. In addition, we present what these responsive practices invoke from the patient in the next turn. We argue that an awareness of these strategies facilitates both the diagnosis and an appropriate therapeutic relationship during the psychiatric assessment interview. Finally, we discuss the clinical significance of our results regarding the patient's agency and the clinician's more conscious patient-centred orientation in the psychiatric assessment procedure.

RESUMEN

Objectives: This study aimed to inquire into the subjective experiences and meaning-making of change of people diagnosed with avoidant personality disorder (AvPD) after attending a treatment program developed for AvPD. Methods: Eighteen AvPD patients were interviewed 1 year after completing their treatment using a semi-structured interview guide. The interviews were analyzed through reflexive thematic analysis. Results: Three main themes were found to capture the various subjective experiences of change. The first main theme "being more alive" included the subthemes "talking and listening together" and "opening up and grounding into myself." The second main theme was "still longing for more," and the third main theme "I cannot even manage therapy" included the subthemes "as if we were together" and "capitulation." Conclusion: Although these findings may not be specific to AvPD, they shed light on the importance of attending to the dynamic interplay of intersubjectivity, social motivations, and agency in a therapeutic context. Discovering a sense of agency within an interpersonal context in which the patient feels connected may lead to them opening up for development in accordance with their social motivational intentions.

RESUMEN

It has been reported that threatening and non-threatening visual stimuli can be distinguished based on the multi-voxel patterns of haemodynamic activity in the human ventral visual stream. Do these findings mean that there may be evolutionarily hardwired mechanisms within early perception, for the fast and automatic detection of threat, and maybe even for the generation of the subjective experience of fear? In this human neuroimaging study, we presented participants ('fear' group: N = 30; 'no fear' group: N = 30) with 2700 images of animals that could trigger subjective fear or not as a function of the individual's idiosyncratic 'fear profiles' (i.e. fear ratings of animals reported by a given participant). We provide evidence that the ventral visual stream may represent affectively neutral visual features that are statistically associated with fear ratings of participants, without representing the subjective experience of fear itself. More specifically, we show that patterns of haemodynamic activity predictive of a specific 'fear profile' can be observed in the ventral visual stream whether a participant reports being afraid of the stimuli or not. Further, we found that the multivariate information synchronization between ventral visual areas and prefrontal regions distinguished participants who reported being subjectively afraid of the stimuli from those who did not. Together, these findings support the view that the subjective experience of fear may depend on the relevant visual information triggering implicit metacognitive mechanisms in the prefrontal cortex. This article is part of the theme issue 'Sensing and feeling: an integrative approach to sensory processing and emotional experience'.

RESUMEN

Objectives: Depression is a leading cause of global disease burden and morbidity among adolescents. Studies have reported higher rates of depression and anxiety secondary to the COVID pandemic and the psychosocial impact of social distancing measures. There is a paucity of literature on the subjective experiences of depressed adolescents in such pandemic circumstances. The objective of this study was to explore the lived experiences of adolescents with major depressive disorder (MDD) during the COVID pandemic, and the impact of the pandemic, and pandemic-related circumstances on adolescents' mental health and coping. Materials and Methods: In-depth interviews with eight adolescents diagnosed with MDD were analyzed using interpretative phenomenological analysis. Results: The analysis revealed three major themes; "The pandemic was arduous," "Negativity in family interactions," and "Effects on depression." Most adolescents coped using excessive screen time as a distraction, and their families perceived them as indolent. Conclusion: The study found that adolescents' experience of depression during the pandemic was extremely overwhelming because, on the one hand, they had to deal with immediate COVID infection-related worries and were not able to adjust to the new routine, not able to concentrate during online classes while also dealing with greater interpersonal discord with their parents and limited social resources for coping. The findings expand the clinical understanding of adolescents' experience of depression during pandemic circumstances and would aid in better management planning.

RESUMEN

In this study, we offer a comprehensive assessment of the phenomenological experience of patients with behavioral-variant frontotemporal dementia (bvFTD) upon retrieval of autobiographical memory. We invited patients with bvFTD and control participants to retrieve autobiographical memories and rate, for each memory, its phenomenological characteristics. We also analyzed the retrieved memories regarding specificity (i.e., whether the memory described a general or a detailed event). Results demonstrated that, compared to control participants, patients with bvFTD attributed lower levels of reliving, back in time (feeling as if going back in time), remembering, realness, visual imagery, auditory imagery, language, emotion, rehearsal, importance, spatial recall and temporal recall to their memories. Lower autobiographical specificity was also observed in patients with bvFTD compared to control participants. Autobiographical specificity in patients with bvFTD was associated with verbal fluency and verbal episodic memory, but not with phenomenological experience. Although autobiographical memories of patients with bvFTD show low ratings of phenomenological experience, the patients may still enjoy some limited subjective experience during autobiographical retrieval.

RESUMEN

Technological advances raise new puzzles and challenges for cognitive science and the study of how humans think about and interact with artificial intelligence (AI). For example, the advent of large language models and their human-like linguistic abilities has raised substantial debate regarding whether or not AI could be conscious. Here, we consider the question of whether AI could have subjective experiences such as feelings and sensations ('phenomenal consciousness'). While experts from many fields have weighed in on this issue in academic and public discourse, it remains unknown whether and how the general population attributes phenomenal consciousness to AI. We surveyed a sample of US residents (n = 300) and found that a majority of participants were willing to attribute some possibility of phenomenal consciousness to large language models. These attributions were robust, as they predicted attributions of mental states typically associated with phenomenality-but also flexible, as they were sensitive to individual differences such as usage frequency. Overall, these results show how folk intuitions about AI consciousness can diverge from expert intuitions-with potential implications for the legal and ethical status of AI.

RESUMEN

The subjective experience of contact with the deceased (VSCD), spontaneous and direct, by people most often in mourning, is neither rare nor new. It's even considered a universal and timeless phenomenon. Yet this psychological and sensory manifestation, which can manifest itself through sight, hearing, smell or touch, remains little known to the general public and health professionals alike. This article is an opportunity for many to discover this phenomenon, also known as necrophany.

RESUMEN

There has been disagreement regarding the relationship among the three components (subjective experience, external performance, and physiological response) of emotional responses. To investigate this issue further, this study compared the effects of active and passive suppression of facial expressions on subjective experiences and event-related potentials (ERPs) through two experiments. The two methods of expression suppression produced opposite patterns of ERPs for negative emotional stimuli: compared with the free-viewing condition, active suppression of expression decreased, while passive suppression increased the amplitude of the late positive potential (LPP) when viewing negative emotional stimuli. Further, while active suppression had no effect on participants' emotional experience, passive suppression enhanced their emotional experience. Among the three components of emotional responses, facial expressions are more closely related to the physiological response of the brain than to subjective experience, and whether the suppression was initiated by participants determines the decrease or increase in physiological response of the brain (i.e. LPP). The findings revealed the important role of individual subjective initiative in modulating the relationship among the components of emotional response, which provides new insights into effectively emotional regulation.

RESUMEN

Until recently, little was known about whether or how autobiographical memory (i.e., memory of personal information) activates eye movement. This issue is now being addressed by several studies demonstrating not only how autobiographical memory activates eye movement, but also how eye movement influences the characteristics of autobiographical retrieval. This paper summarizes this research and presents a hypothesis according to which fixations and saccades during autobiographical retrieval mirror the construction of the visual image of the retrieved event. This hypothesis suggests that eye movements during autobiographical retrieval mirror the attempts of the visual system to generate and manipulate mental representations of autobiographical retrieval. It offers a theoretical framework for a burgeoning area of research that provides a rigorous behavioral evaluation of the phenomenological experience of memory.

RESUMEN

BACKGROUND: There is growing evidence for the therapeutic effects of psychedelics. However, it is still uncertain how these drugs interact with serotonergic antidepressants (serotonin reuptake inhibitors (SRIs)). OBJECTIVE: This study explores the interaction between psychedelics and SRIs in terms of therapeutic effects. The objective is to compare acute psychedelic effects and subsequent changes in well-being and depressive symptoms among 'SRI -' individuals (not on psychiatric medication) and 'SRI +' individuals (undergoing SRI treatment). METHODS: Using prospective survey data, the study employs multivariate analysis of covariance (MANCOVA) and linear mixed effect models to analyse subjective differences and changes in well-being and depressive symptoms pre- and post-psychedelic experiences. RESULTS: Results indicate that 'SRI -' participants experience significantly more intense subjective effects compared to 'SRI +' participants (F = 3.200, p = 0.016) in MANCOVA analysis. Further analysis reveals 'SRI -' individuals report stronger mystical (18.2% higher, p = 0.048), challenging (50.9% higher, p = 0.001) and emotional breakthrough experiences (31.9% higher, p = 0.02) than 'SRI +' individuals. No differences are observed in drug-induced visual effects (p = 0.19). Both groups exhibited similar improvements in well-being and depressive symptoms after the psychedelic experience. CONCLUSION: Individuals presumed to be on serotonergic antidepressants during psychedelic use display reduced subjective effects but similar antidepressant effects compared to those not undergoing SRI treatment. Further controlled research is needed to comprehend the interplay between serotonergic antidepressants and psychedelics, illuminating potential therapeutic benefits and limitations in clinical contexts.

RESUMEN

Dis-sociality (DS) reflects the impairment of social experience in people with schizophrenia; it encompasses both negative features (disorder of attunement, inability to grasp the meaning of social contexts, the vanishing of social shared knowledge) and positive features (a peculiar set of values, ruminations not oriented to reality), reflecting the existential arrangement of people with schizophrenia. DS is grounded on the notion of schizophrenic autism as depicted by continental psychopathology. A rating scale has been developed, providing an experiential phenotype. Here we present the Autism Rating Scale for Schizophrenia - Revised English version (ARSS-Rev), developed on the Italian version of the scale. The scale is provided by a structured interview to facilitate the assessment of the phenomena investigated here. ARSS-Rev is composed of 16 distinctive items grouped into 6 categories: hypo-attunement, invasiveness, emotional flooding, algorithmic conception of sociality, antithetical attitude toward sociality, and idionomia. For each item and category, an accurate description is provided. Different intensities of phenomena are assessed through a Likert scale by rating each item according to its quantitative features (frequency, intensity, impairment, and need for coping). The ARSS-Rev has been able to discriminate patients with remitted schizophrenia from euthymic patients with psychotic bipolar disorder. This instrument may be useful in clinical/research settings to demarcate the boundaries of schizophrenia spectrum disorders from affective psychoses.

RESUMEN

The nature of subjective conscious experience, which accompanies us throughout our waking lives, and how it is generated, remain elusive. One of the challenges in studying subjective experience is disentangling the brain activity related to the sensory stimulus processing and stimulus-guided behavior from those associated with subjective perception. Blindsight, a phenomenon characterized by the retained visual discrimination performance but impaired visual consciousness due to damage to the primary visual cortex, becomes a special entry point to address this question. However, to fully understand the underlying neural mechanism, relying on studies involving human patients alone is insufficient. In this paper, we tried to address this issue, by first introducing the well-known cases of blindsight, especially the reports on subjective experience in both human and monkey subjects. And then we described how the impaired visual awareness of blindsight monkeys has been discovered and further studied by specifically designed tasks, as verbal reporting is not possible for these animals. Our previous studies also demonstrated that many complex visually guided cognitive processes were still retained despite the impairment of visual awareness. Further investigation needs to be conducted to explore the relationship between visually guided behavior, visual awareness and brain activity in blindsight subjects.

RESUMEN

Individuals in the early stages of dementia often endure elevated levels of stress and anxiety, which can hinder their ability to adapt to the progression of dementia. To mitigate the negative impacts of dementia more effectively, it is necessary to explore the trajectory of the adaptation process of persons living with dementia. This study aimed to construct a theoretical framework for the adaptation process of individuals in the early stages of dementia. Participants were dyads of persons diagnosed with mild dementia or mild cognitive impairment (≥ 60 years of age) and their primary family caregivers. This longitudinal study used a grounded theory approach to explore the adaptation trajectory changes in persons with mild dementia over a 3-year period. Data were collected from dyads with face-to-face interviews. Analysis of the interview data revealed the core category was 'Coexisting with anomie: Progressive disappointment and striving', which was comprised of three categories: awareness of alienation, unsettled feelings, and restorative avoidance coping. Categories changed depending on levels of cognition and constituted progressive and cyclical dynamic processes. Four contextual factors positively or negatively influenced adaptation: level of insight about dementia, personal traits, caregiving style of the caregiver, and level of social interactions. These findings provide a new perspective about the mental health of persons in early-stage dementia. Understanding coexisting with anomie and related influencing factors could facilitate the development of support interventions by mental health nursing staff, which could improve emotional safety, promote psychological well-being, and increase quality of life for persons living with dementia.

RESUMEN

BACKGROUND: In the last two decades, much neuroscientific research has been done on the pathomechanisms of catatonia. However, catatonic symptoms have mainly been assessed with clinical rating scales based on observer ratings. Although catatonia is often associated with strong affective reactions, the subjective domain of catatonia has simply been neglected in scientific research. METHODS: The main objective of this study was to modify, extend and translate the original German version of the Northoff Scale for Subjective Experience in Catatonia (NSSC) and to examine its preliminary validity and reliability. Data were collected from 28 patients diagnosed with catatonia associated with another mental disorder (6A40) according to ICD-11. Descriptive statistics, correlation coefficients, internal consistency and principal component analysis were employed to address preliminary validity and reliability of the NSSC. RESULTS: NSSC showed high internal consistency (Cronbach's alpha = 0.92). NSSC total scores were significantly associated with Northoff Catatonia Rating Scale (r = 0.50, p < .01) and Bush Francis Catatonia Rating Scale (r = 0.41, p < .05) thus supporting its concurrent validity. There was no significant association between NSSC total score and Positive and Negative Symptoms Scale total (r = 0.26, p = .09), Brief Psychiatric Rating Scale (r = 0.29, p = .07) and GAF (r = 0.03, p = .43) scores. CONCLUSION: The extended version of the NSSC consists of 26 items and was developed to assess the subjective experience of catatonia patients. Preliminary validation of the NSSC revealed good psychometric properties. NSSC is a useful tool for everyday clinical work to assess the subjective experience of catatonia patients.

RESUMEN

PURPOSE: People with functional movement disorders (FMD) are commonly seen in neurology clinics. Despite a recent increase in research, no standardised treatment pathway across the UK exists. Currently only a few qualitative studies in FMD with a focus on psychological aspects and diagnosis have been published. This study aimed to understand people with FMD perceptions of their physiotherapy treatment. METHOD: Qualitative web-based interviews were conducted with seven participants and an interpretive phenomenological approach was used to identify themes from the data. RESULTS: Four themes were identified; 1) my brain, mind and body are all me, 2) physiotherapy; what helps and what doesn't, 3) what recovery is to me, and 4) barriers to treatment. Participants desired a combination of psychological and physical approaches, which were holistic, individualised, and delivered by experienced physiotherapists. Limited availability and funding of specialist treatments were barriers to recovery. CONCLUSION: Holistic management combining psychological and physiological systems seems to be crucial for effective management of FMD. Large variations in physiotherapy treatment exist across the UK. It is hoped that increasing the understanding, amongst healthcare professionals will lead to the development of timely and appropriate pathways for patients that otherwise find themselves lost between medical specialities.IMPLICATIONS FOR REHABILITATIONPatients report more positive experiences when a combined and detailed psychological and physiological explanation to their symptoms is given.An individualised approach working with the patient on activities they find challenging is more preferable than group exercise or impairment based (e.g., strengthening/stretching) treatments.Having a physiotherapist who is experienced in treating functional movement disorders or prepared to learn and understand them helped with adherence to treatment.
