Eine veränderte Interozeption ist ein zentrales Korrelat der Anorexia nervosa (AN) und stellt einen potentiellen Ansatz in der Genesung der AN dar. Erste Ergebnisse zur Wirksamkeit von Yoga als körperorientierte Methode in der Therapie der AN sind vielversprechend. Dennoch liegen bislang unzureichende empirische Befunde bezüglich der Frage vor, auf welche Weise Yoga-Strategien und Yoga-Elemente wie Körperhaltungen, Entspannungs-, Atem-, und Meditationsübungen eingesetzt werden sollten. Vor diesem Hintergrund führten wir eine qualitative Pilotstudie mit einer Stichprobe von n=6 Patientinnen mit AN durch, die sich im Anschluss an eine klinische stationäre Behandlung in einer pädagogisch-therapeutischen Facheinrichtung der Jugend- und Eingliederungshilfe (SGB VIII/XII) befanden. Die Studienteilnehmerinnen erhielten eine einstündige Hatha-Yoga-Intervention über mindestens 12 Wochen. Nach der Yoga-Intervention wurden ½- bis 1-stündige halbstrukturierte Leitfadeninterviews zu den Erfahrungen mit den verwendeten Yoga-Strategien durchgeführt. Die Interviews wurden mittels Grounded Theory ausgewertet. Auf der obersten Analyseebene wurden 4 Kategorien differenziert: Angaben 1) zum Beschwerdebild der Studienteilnehmerinnen, 2) zu als hilfreich erlebten Elementen des therapeutischen Rahmens, 3) zu als hilfreich erlebten Yoga-Strategien sowie 4) zu subjektiv wahrgenommenen Konsequenzen der Yoga-Strategien. Bezüglich der als hilfreich erlebten Yoga-Strategien ergaben die Analysen 4 Subkategorien: Merkmale 1) der Bewegungselemente, 2) der Meditations- und Atemübungen, 3) der Entspannungsübungen sowie 4) allgemeine Hinweise zur Durchführung. Die Ergebnisse geben erste Hinweise für die Konzeption von Yoga in der Therapie der AN und zu potentiellen Wirkmechanismen. Weiterführende qualitative sowie quantitative Studien zu u. a. Wirksamkeit, Kontraindikationen oder Mediator- sowie Moderatorvariablen sind erforderlich, um das Potenzial von Yoga in der Therapie der AN noch besser bewerten zu können.
Keeping the breath in mind
(2021)
Scientific interest in the brain and body interactions has been surging in recent years. One fundamental yet underexplored aspect of brain and body interactions is the link between the respiratory and the nervous systems. In this article, we give an overview of the emerging literature on how respiration modulates neural, cognitive and emotional processes. Moreover, we present a perspective linking respiration to the free-energy principle. We frame volitional modulation of the breath as an active inference mechanism in which sensory evidence is recontextualized to alter interoceptive models. We further propose that respiration-entrained gamma oscillations may reflect the propagation of prediction errors from the sensory level up to cortical regions in order to alter higher level predictions. Accordingly, controlled breathing emerges as an easily accessible tool for emotional, cognitive, and physiological regulation.

Cognition is shaped by signals from outside and within the body. Following recent evidence of interoceptive signals modulating higher-level cognition, we examined whether breathing changes the production and perception of quantities. In Experiment 1, 22 adults verbally produced on average larger random numbers after inhaling than after exhaling. In Experiment 2, 24 further adults estimated the numerosity of dot patterns that were briefly shown after either inhaling or exhaling. Again, we obtained on average larger responses following inhalation than exhalation. These converging results extend models of situated cognition according to which higher-level cognition is sensitive to transient interoceptive states.
The Role of Interoceptive Sensibility and Emotional Conceptualization for the Experience of Emotions
(2021)
The theory of constructed emotions suggests that different psychological components, including core affect (mental and neural representations of bodily changes), and conceptualization (meaning-making based on prior experiences and semantic knowledge), are involved in the formation of emotions. However, little is known about their role in experiencing emotions. In the current study, we investigated how individual differences in interoceptive sensibility and emotional conceptualization (as potential correlates of these components) interact to moderate three important aspects of emotional experiences: emotional intensity (strength of emotion felt), arousal (degree of activation), and granularity (ability to differentiate emotions with precision). To this end, participants completed a series of questionnaires assessing interoceptive sensibility and emotional conceptualization and underwent two emotion experience tasks, which included standardized material (emotion differentiation task; ED task) and self-experienced episodes (day reconstruction method; DRM). Correlational analysis showed that individual differences in interoceptive sensibility and emotional conceptualization were related to each other. Principal Component Analysis (PCA) revealed two independent factors that were referred to as sensibility and monitoring. The Sensibility factor, interpreted as beliefs about the accuracy of an individual in detecting internal physiological and emotional states, predicted higher granularity for negative words. The Monitoring factor, interpreted as the tendency to focus on the internal states of an individual, was negatively related to emotional granularity and intensity. Additionally, Sensibility scores were more strongly associated with greater well-being and adaptability measures than Monitoring scores. Our results indicate that independent processes underlying individual differences in interoceptive sensibility and emotional conceptualization contribute to emotion experiencing.

Interoception is an often neglected but crucial aspect of the human minimal self. In this perspective, we extend the embodiment account of interoceptive inference to explain the development of the minimal self in humans. To do so, we first provide a comparative overview of the central accounts addressing the link between interoception and the minimal self. Grounding our arguments on the embodiment framework, we propose a bidirectional relationship between motor and interoceptive states, which jointly contribute to the development of the minimal self. We present empirical findings on interoception in development and discuss the role of interoception in the development of the minimal self. Moreover, we make theoretical predictions that can be tested in future experiments. Our goal is to provide a comprehensive view on the mechanisms underlying the minimal self by explaining the role of interoception in the development of the minimal self.
