Am I in Control? The Effect of Depersonalization on the Sense of Agency

Impact of Dancing on Physical and Mental Health: A Systematic Literature Review

Dance Research, Journal Year: 2024, Volume and Issue: 42(2), P. 220 - 256

Published: Oct. 29, 2024

Dance, as an expressive art, has increasingly been recognised for its significant impact on physical and mental health. This comprehensive literature review delves into the multifaceted effects of dancing across various populations settings, emphasising implementation in Dance Movement Therapy (DMT) Health (DfH) programmes. Central themes explored include: (1) role dance enhancing neurological cognitive functions through DMT; (2) therapeutic potential health emotional well-being, primarily (3) benefits realised DfH encompassing aspects like cardiovascular health, muscular strength, flexibility, balance, coordination. In this study, forty-eight (48) peer-reviewed studies from prominent databases, spanning period 2020 to 2023 were scrutinised. The analysis reveals extensive applications dance, rehabilitative therapy neurodegenerative disorders a catalyst psychological resilience social integration. Crucially, identifies under-researched areas such long-term therapy, impacts specific demographic groups, integration technology practices. Additionally, findings highlight diverse nature within DMT DfH, underscoring both empirical evidence challenges, including accessibility cultural adaptability. thus acts retrospective examination forward-looking guide, offering insights healthcare professionals, researchers, policymakers complex relationship between overall human

Survival, Attachment, and Healing: An Evolutionary Lens on Interventions for Trauma-Related Dissociation

Psychology Research and Behavior Management, Journal Year: 2024, Volume and Issue: Volume 17, P. 2403 - 2431

Published: June 1, 2024

Purpose: Dissociation is a necessary part of our threat response system, common to all animal species, normally temporarily activated under conditions extreme or inescapable threat. Pathological dissociation, however, continues occur after the initial has passed, in reminders inaccessibility safety and security. Present across spectrum psychiatric diagnoses, recurrent dissociative symptoms are linked severe trauma exposure, insecure attachment, treatment non-response, maladaptive coping behaviors such as substance use, suicidality, self-harm. However, empirical studies testing treatments specific processes remain scarce. This narrative review summarizes existing provides theoretical, neurobiological, evolutionary perspectives on for pathological dissociation. Methods: A systematic search five databases (MEDLINE, EMBASE, APA PsycINFO, CINAHL plus, Scopus) was conducted April 13, 2023. Peer-reviewed clinical with adult participants, assessing intervention effects symptoms, were included. Results thematically analyzed summarized. Results: Sixty-nine identified, mainly focused posttraumatic stress disorder, trauma-exposed populations, borderline personality disorder. Psychotherapy studied 72.5% studies; other interventions included medications neurostimulation. The majority reported positive outcomes, despite heterogeneous interventions. primary objective only minority. Conclusion: dissociation complex phenomenon involving brain body systems designed perceiving responding threats, requiring an individualized approach. literature emerging regarding potentially evidence-based help those impacted by symptoms. When contextualized within neurobiological perspective, these can be understood facilitating internal and/or relational sense safety, resulting symptom reduction.

Behavioural, autonomic, and neural responsivity in depersonalisation-derealisation disorder: A systematic review of experimental evidence

Neuroscience & Biobehavioral Reviews, Journal Year: 2024, Volume and Issue: 163, P. 105783 - 105783

Published: June 27, 2024

Depersonalisation-derealisation disorder (DDD) is characterised by distressing experiences of separation from oneself and/or one's surroundings, potentially resulting alterations in affective, cognitive, and physiological functions. This systematic review aimed to synthesise current experimental evidence relevance proposed mechanisms underlying DDD, appraise existing theoretical models, inform future research developments. Studies were included if they tested explicit hypotheses DDD samples, with manipulations at least one independent variable, alongside behavioural, subjective, neurological, affective dependent variables. Some for diminished subjective responsivity aversive images sounds, hyperactivation neurocircuits associated emotional regulation when viewing emerged, corroborating neurobiological models DDD. Inconsistencies present regarding behavioural autonomic facial expressions, memory, self-referential processing. Common confounds small sample sizes, medication, comorbidities. Alterations reactivity appear be DDD; however, further employing more rigorous designs required provide stronger these possible mechanisms.

Self-portrait of a Stranger: Self-face Representation and Interoception in Depersonalization Experiences

Depersonalization is a condition that makes people feel detached from one’s self, body and others. The representation of own face salient bodily aspect self-awareness identity, empirical evidence suggests individuals with depersonalization disorder experience disrupted perception their faces when viewing themselves in photographs or the mirror, which has been corroborated by first-person reports. However, no study had yet explored state long-term self-face representations stored visual memory context depersonalization. By visualising how saw “in mind’s eye”, this provides first for relationship between symptoms impairments representation. Individuals reporting more frequent intense lower accuracy, but somewhat counterintuitively, also higher precision informational content These results suggested high were representing distinct, inaccurate, facial identity as themselves. high-depersonalization participants rated visibly emotionless younger appearance than those low-depersonalisation participants, according to independent raters. Furthermore, specific aspects symptomatology, related anomalous experiences, identified most highly these characteristics. Finally, an intriguing role interoceptive sensibility was revealed both representational accuracy symptoms.

Emotion, Embodiment, and Aesthetic Appraisal: The Impact of Interoceptive Abilities and Art Type

Published: Sept. 3, 2023

Emotions are considered important in aesthetic experience. Given that emotions have bodily dimensions, it follows interoception—the ability to perceive signals accurately—may play a role experiences of art. This raises the intriguing question whether variation interoceptive abilities relates differences art We addressed this possibility across two studies employed objective and subjective measures abilities. In Study 1, we examined impact accuracy (IAc) changes (heart rate skin conductance) while viewing on participants’ appraisal emotional response abstract representational artworks. IAc was positively related participants' reactions art, particularly paintings, no relationship found for appraisal. also observed heart change higher Moreover, first time, conductance did not differ by type. 2, assessed individual self-reported interoception emotion As were mainly ratings response, All all, propose an interplay between artwork type, emotions, plays crucial experience
