Schmerzen begleiten uns alle. Licht in das Halbwissen über Schmerz und den Umgang damit zu bringen, ist Ziel dieses Buchs. Eine Novelle als Rahmenhandlung soll die Schmerzen im Leben der Menschen anschaulich machen. Was dem Helden der Geschichte widerfährt, wird im Sachbuchtext gespiegelt: die Entstehung von Schmerz, seine Linderung und Heilung, di...

Cocaine use disorder is associated with maladaptive decision-making behavior, which strongly contributes to the harmful consequences of chronic drug use. Prior research has shown that cocaine users exhibit impaired neuropsychological test performances, particularly with regard to attention, learning, and memory but also in executive functions such...

Objective. Self-reports of pain are important for an adequate therapy. This is a problem with patients and infants who are restricted in providing an accu- rate verbal estimation of their pain. Reliable, real- time, economical, and non-invasive physiological correlates might contribute to a more comprehen- sive description of pain. Salivary alpha-a...

Pain is an experience including physiological and psychological factors. We assume that emotions may be elicited and increased through self-perceived role identity and that change of role identity alters quality and intensity of pain perception. We used role-play strategies to assess whether pain can be better tolerated whenever, in an unavoidable...

To correlate the pharmacological effects of the fixed herbal combination STW 5 (Iberogast) containing nine extract components with its confirmed clinical efficacy, ex vivo/in vitro absorption tests were performed. For the investigation, the everted gut sac technique and, in a pilot study, the Caco-2-cell model were used. The absorption rate of the...

Kurztext ADHS ist keine organische Krankheit. Es ist ein Konglomerat sozial als störend empfundener Verhaltensweisen. In etlichen Ländern Europas wird - neuerdings zunehmend - jedes vierte Kind mit ADHS diagnostiziert und meist mit verschreibungspflichtigen Stimulanzien behandelt. Diese Stimulanzien sind suchterzeugende Drogen, die therapeutisch un...

Dataset. Each row in the dataset represents a decision task and includes an individual identifier (1 to 27), the gender of the participant (F or M), the probability with which the amount CHF 50 would be obtained in the risky option, the amount guaranteed by the certain option, and the decision made by the participant (0 for the certain option, and...

Quantum decision theory (QDT) is a novel theory of decision making based on the mathematics of Hilbert spaces, a framework known in physics for its application to quantum mechanics. This framework formalizes the concept of uncertainty and other effects that are particularly manifest in cognitive processes, which makes it well suited for the study o...

Quantum decision theory (QDT) is a recently developed theory of decision making based on the mathematics of Hilbert spaces, a framework known in physics for its application to quantum mechanics. This framework formalizes the concept of uncertainty and other effects that are particularly manifest in cognitive processes, which makes it well suited fo...

Watch or even think of someone biting into a juicy lemon and your saliva will flow. This is a phenomenon of resonance, best described by the Perception–Action Model, where a physiological state in a person is activated through observation of this state in another. Within a broad framework of empathy, including manifold abilities depending on the Pe...

Background: Exceptional experiences (EE) are experiences that deviate from ordinary experiences, for example precognition, supernatural appearances, or déjà vues. In spite of the high frequency of EE in the general population, little is known about their effect on mental health and about the way people cope with EE. This study aimed to assess the q...

Das Bewusstsein ermöglicht es uns, Praktiken zur Heilung des versehrten Körpers zu entwickeln. Der Fokus der Arbeit liegt auf der im katholischen Christentum verbreiteten Tradition der Fürbitte bei Krankheit mit Hilfe von Reliquien und Körperteil-Votiven. Die Vorgangsweisen dieser Jahrtausende alter religiöser Praktiken und vorerst gesicherter medi...

Das menschliche Verhalten verbindet den Willen mit der Handlung und ermöglicht so die Anpassung des Menschen an sein natürliches und soziales Umfeld. Mediziner, Ökonomen und Psychologen haben zahlreiche Verhaltensmodelle entworfen, dennoch ist unser Wissen über die grundlegenden Prozesse noch immer begrenzt. Diese Arbeit basiert auf der Annahme, da...

Pain threshold and pain tolerance of heat noxious stimuli were assessed to determine whether they are equivalent when measured at three equidistant sites of both volar forearms. Heat pain threshold and tolerance were measured in 18 healthy volunteers using a standard stimulation device consisting of a thermode. Pain threshold and pain tolerance did...

Geteiltes Leid ist halbes Leid." The old German proverb reflects the fact that sharing a bad emotion or feeling with someone else may lower the psychological strain of the person experiencing sorrow, mourning or anger. On the other hand the person showing empathy will take literally a load from its counterpart, up to physiological reaction of the p...
