Hintergrund: Nach Damasios Theorie der Somatischen Marker werden Entscheidungen in komplexen Situationen durch die Wahrnehmung physiologischer Vorgänge (Interozeption) sowie durch die individuelle Fähigkeit zu dieser Wahrnehmung (Interozeptivität) beeinflusst. Im Sinne zielgerichteten Verhaltens müssen die auf diese Weise gewonnenen, emotional mediierten Informationen bei Bedarf reguliert werden, wofür präfrontal initiierte, inhibitorische Prozesse maßgeblich sind. Die hierfür notwendige Inhibitionskapazität kann durch die vagal mediierte und präfrontal modulierte Herzratenvariabilität (HRV) peripherphysiologisch quantifiziert werden. Die Interaktion interozeptiver und inhibitorischer Fähigkeiten bei Entscheidungen unter emotional ablenkenden Bedingungen ist im klinischen Kontext insbesondere bei Krankheitsbildern mit disinhibitorischen und körperwahrnehmungsbezogenen Symptomen relevant. Die vorliegende Studie untersuchte Entscheidungsprozesse unter emotionalen Einflüssen bei Patienten mit Panikstörung und Somatoformen Störungen. Methode: 17 Patienten mit Panikstörung und 20 Patienten mit Somatoformen Störungen wurden im stationären Setting einer psychosomatischen Klinik untersucht. Die Interozeptivität wurde mit einer Trackingaufgabe des Herzschlages bestimmt, zur HRV-Bestimmung ein EKG unter Ruhebedingung aufgezeichnet. Entscheidungsprozesse wurden mit Hilfe einer emotionalen Flanker Task und der Iowa Gambling Task untersucht. Ergebnisse: Bei Patienten mit Panikstörung zeigte sich eine negative Interaktion zwischen HRV und Interozeptivität, die darüber hinaus mit der Ablenkbarkeit durch emotionale Reize in der Flanker Task assoziiert war. Bei Patienten mit Somatoformen Störungen traten diese Zusammenhänge nicht auf. Patienten mit Panikstörung zeigten eine signifikant niedrigere HRV im Vergleich mit Patienten mit Somatoformen Störungen. Diskussion: Die Ergebnisse legen nahe, dass Interozeptivität und Inhibitionskapazität jeweils allein nicht ausreichend sind, um die untersuchten klinischen Störungen spezifisch zu charakterisieren. Eine negative Interaktion beider Maße allerdings scheint spezifisch mit der Panikstörung assoziiert zu sein und spricht für eine präzise, aber dysfunktionale interozeptive Wahrnehmung bei verminderter Regulationskapazität, was sich in der Beeinflussung der Aufmerksamkeitsausrichtung durch emotionale Prozesse manifestiert.

Bulimia nervosa (BN) is characterized by recurrent episodes of binge eating and compensatory behaviors, such as self- induced vomiting. Body image disturbance is also prominent in BN. Current research is trying to determine which dimensions and sensory domains of body perception are affected in BN. Regarding heartbeat perception, findings are inconclusive, with some studies reporting reduced and others reporting unaltered interoceptive accuracy in BN. The current study contributes further data on heartbeat perception by using an indicator of the cortical processing of cardio- afferent signals (heartbeat evoked potentials, HEPs). We investigated 22 women with current or partially remitted BN (BMI 23.94[3.61]; age 31.86[11.20]) and 22 healthy women (HC; BMI 24.24[3.37]; age 31.00[10.15]). Participants performed a heartbeat perception task (according to Schandry) with concurrent 64- channel- EEG and ECG recording. HEPs were calculated as mean EEG amplitudes in the interval 455- 595ms after the R- peak of the ECG. Results show no significant differences between the BN and HC groups, neither for heartbeat perception, HEPs, or mean heartrate. These results confirm previous findings of intact heartbeat perception in BN. In addition, cortical processing of cardio- afferent signals is unaltered. Heartbeat perception is particularly relevant for emotion processing and regulation. The previously reported emotion- regulation deficits in BN appear not to be based on altered CNS processing of cardiac signals [less ▲]

Little is known about the conscious experience of internal bodily sensations in preschool-aged children. Given that preschoolers are in the most rapid phase of brain development, and display profound emotional development, it was the aim of the present study to establish an adapted interoceptive accuracy paradigm and to investigate associations between sociodemographic (age, sex) and emotional variables with interoceptive accuracy. Forty-nine children (aged 4-6 years) completed the jumping jack paradigm, a heartbeat tracking paradigm, which includes a noninvasive physical perturbation via performing jumping jacks for 10 seconds. An interoceptive accuracy score was based on the comparison between self-reported and objectively recorded heart rate prior to and after completion of jumping jacks. Children also completed validated measures for emotion recognition and emotion regulation. Children’s objectively recorded heart rate significantly increased after the JJP by 20 bpm on average. There was a positive relationship between reactivity on self-reported heart rate and objectively recorded heart rate increase. The derived scores for interoceptive accuracy increased with age, suggesting older children to report more self-reported heart rate change than objectively recorded, but were unrelated to children’s sex or BMI. While emotion recognition and regulation significantly increased with age, the interoceptive accuracy score was unrelated to emotion recognition, but marginally associated to emotion regulation. Children with higher interceptive accuracy score (i.e., self-reporting more heart rate change than objectively recorded) received lower emotion regulation score. The present study is the first to depict a novel behavioral paradigm to assess interoceptive accuracy in preschool-aged children. [less ▲]

Aims: Recent accounts have suggested the involvement of interoceptive processes in consumption behavior for alcohol and other drugs. However, there is a paucity of empirical support for a direct association with physiologically assessed individual differences in interoceptive awareness (IA). The current research explored this postulated link and examined the interplay with positive outcome expectancies of alcohol consumption. Method: IA of alcohol-dependent adult in- and outpatients was measured with an objective electrocardiogram heart rate tracking task. Tension reduction expectancies (TRE) and drinking compulsions/obsessions were assessed with self-report questionnaires. Results: No direct associations of IA with drinking compulsions/obsessions were found. However, IA and TRE interacted as predictors of drinking compulsions and drinking obsessions. Conclusion: The results corroborate the suggestion that neglect of bodily feedback might be a maintaining factor for drinking behavior. [less ▲]

This contribution assesses data protection concerns relating to the processing of personal data carried out pursuant to Article 20 of the interoperability proposals, which were published by the European Commission on 12 December 2017. The proposals seek to enable all centralised EU databases for security, border and migration management to be interconnected by 2023. Under Article 20 of the proposals, Member States would be permitted to implement national provisions that allow national police authorities to query one of the interoperability components with biometric taken during an identity check. Such queries shall prevent irregular migration and ensure a high level of security within Union. In particular, this article seeks to examine the data protection concerns arising with regard to streamlined law enforcement access to non-law enforcement databases included in the interoperable framework, and addresses risks for individuals to become subject to unfair processing under Article 20 of the interoperability proposal.
