AbstractBackgroundDeficient regulation of stress plays an important role in the escalation of substance use, addiction and relapse. Accumulating evidence suggests dysregulations in cognitive and reward-related processes and the underlying neural circuitry in cannabis dependence. However, despite the important regulatory role of the endocannabinoid system in the stress response, associations between chronic cannabis use and altered stress processing on the neural level have not been systematically examined.MethodsAgainst this background, the present functional magnetic resonance imaging (fMRI)study examined psycho-social stress processing in cannabis-dependent males (n = 28) and matched controls (n = 23) using an established stress-induction paradigm (Montreal Imaging Stress Task) that combines computerized (adaptive) mental arithmetic challenges with social evaluative threat.ResultsDuring psycho-social stress exposure, but not the no-stress condition, cannabis users demonstrated impaired performance relative to controls. In contrast, levels of experienced stress and cardiovascular stress responsivity did not differ from controls. Functional MRI data revealed that stress-induced performance deteriorations in cannabis users were accompanied by decreased precuneus activity and increased connectivity of this region with the dorsal medial prefrontal cortex.LimitationsOnly male cannabis-dependent users were examined, the generalizability in female users remains to be determined.ConclusionTogether, the present findings provide first evidence for exaggerated stress-induced cognitive performance deteriorations in cannabis users. The neural data suggest that deficient stress-related dynamics of the precuneus may mediate the deterioration of performance on the behavioral level.

Zusammenfassung. Die vorliegende Arbeit stellt die bisherigen empirischen Befunde zur Sprachgrundfrequenz (f0) in Paargesprächen vor und untersucht, wie sich die f0 nach einer experimentellen Stressinduktion im anschließenden spontanen Gespräch zwischen den Partner_innen verändert, wie die f0 mit der verbalen Stressäußerung zusammenhängt und wie sie zwischen den beiden Partner_innen kovariiert. Von 128 heterosexuellen Paaren nahm jeweils eine Person pro Paar am Trier Social Stress Test (TSST) teil. Die dem TSST vorangehende und anschließende naturalistische Interaktion zwischen den Partner_innen wurde gefilmt und nach Gesprächsthema und Art der Stressäußerung kodiert. Wie vorherige Studien zur f0 im Paargespräch zeigte auch die vorliegende Studie, dass die f0 wichtige Informationen über die Partnerschaft enthält. Während eine Erhöhung der f0 in Gesprächen über einen paarinternen Stressor (d.h. bei Konfliktgesprächen) mit negativen Kommunikationsmustern einherging, zeigte die vorliegende Studie, dass die f0 bei Gesprächen über einen paarexternen Stressor (d.h. beim TSST) mit emotionsorientierten Stressäußerungen einherging, also einer für den Stressbewältigungsprozess förderlichen Art der Kommunikation. Die Oszillatorenmodelle zeigen darüber hinaus, dass eine Kopplung der f0 zwischen den Partner_innen besteht, was darauf hindeutet, dass die nicht gestressten Partner_innen auf die paraverbalen Stressäußerungen der gestressten Partner_innen mit ihren eigenen paraverbalen Stressäußerungen reagieren.

The Relationship

Abstract. This study examined whether the relationship between subjective and physiological outcomes of stress, and the responsivity to stressors, are affected by whether participants can see a visual display of their physiological output. Participants were randomly assigned to have a visible view of their physiological output readings, or to a condition in which physiological output readings were out of view. Participants individually completed a 30-min laboratory study including the modified Trier Social Stress Task. Both physiological markers of stress (heart rate and blood pressure) and subjective evaluations of stress (visual analog scale) were measured. Results found little congruency across subjective and physiological measures of stress. The visible visual display condition had elevated physiological arousal, while no group differences were observed in self-reported stress. Findings from the study provide insight into the use of visual physiological displays and hold practical implications for both the measurement of stress in research, and the development of wearable technologies without accompanying response strategies.
