Most people suffer from intrusive memories in the aftermath of trauma. For survivors' well-being, it is key that these intrusions are controlled. Memory control can be exerted through retrieval suppression. Poor suppression, however, should associated with persistent distressing and posttraumatic stress disorder (PTSD). This study tested hypothesis individual differences suppression predict after Retrieval was examined think/no-think task (TNT) using behavioral event related potential (ERP)...

Dogs are known to have stress and anxiety reducing effects. Several studies shown that dogs able calm people during cognitive performance stressors. Recently, therapy been proposed as a treatment adjunct for post-traumatic disorder patients. In this study we aimed investigate, whether also anxiety- effect "traumatic stressors." 80 healthy female participants were randomly assigned one of four conditions. They exposed "traumatic" film clip (trauma-film-paradigm). For group friendly dog was...

We present performance results concerning the validation for anxiety level detection based on trained mathematical models using supervised machine learning techniques. The model training is biosignals acquired in a randomized controlled trial. Wearable sensors were used to collect electrocardiogram, electrodermal activity, and respiration from spider-fearful individuals. designed applied ten approaches data labeling considering individual as well subjective ratings.

Effective communication and bonding between species depend on understanding the emotional state expressive behavior of counterpart. This is particular importance for human-horse relationships, as misunderstanding horses’ communicative signals can easily lead to severe injuries. While published evidence suggests that human ability correctly interpret equine affective states far from perfect, this inconclusive regarding influence previous experience with horses. Further, role emotion...

The way we interpret information shapes our perception of reality. Predictive processing frameworks propose that the ability to update interpretations based on disconfirming is key recovery from potentially traumatic events (PTEs). However, direct evidence for this assumption scarce and comes studies using paradigms with low ecological validity. Here, investigate association between inflexible interpretation updating (IIU) symptoms posttraumatic stress disorder (PTSD) in a comprehensive...

Hospitals, and particularly intensive care units (ICUs), are demanding stressful workplaces. Physicians nurse staff exposed to various stressors: emergency situations, patients' deaths, team conflicts. Correspondingly, several studies describe increased rates of PTSD symptoms other mental health problems in hospital staff. Therefore, it is important identify factors that lower the risk psychopathological symptoms. High levels sense coherence (SOC) general resilience as well an internal locus...

As an alternative to interoceptive paradigms that depend on the participants' active cooperation, two studies are presented show startle methodology may be employed study visceral afferent processing.

Individuals working in high-risk occupations (e.g., emergency staff) are exposed to high levels of occupational stress including traumatic events. Correspondingly, several studies report rates mental health problems among these occupations. Pet ownership has been associated with better health. However, date a study on the association between pet and indicators is missing. The present cross-sectional survey (N = 580) investigated ownership, attachment pets, health-benefitting factors (i.e.,...

Background: Recent findings suggest that disruptions of sleep-related memory processing are involved in the development posttraumatic stress symptoms. More specifically, exposure to an analogue traumatic event resulted fewer intrusive memories, when it was followed by sleep instead continued wakefulness. However, competing evidence suggests deprivation may reduce re-experiencing. To address these conflicting accounts, we examined how – as opposed partial modulates explicit and implicit...

Equine-assisted therapies are becoming increasingly popular for addressing physical and psychological disabilities in clients. The role of the horse's welfare equine-assisted service receives increasing attention research. Several studies have shown that horses able to perceive human emotions respond stress responses.

Although humans usually prefer mates that resemble themselves, mating preferences can vary with context. Stress has been shown to alter in animals, but the effects of stress on human are unknown. Here, we investigated whether alters men's preference for self-resembling mates. Participants first underwent a cold-pressor test (stress induction) or control procedure. Then, participants viewed either neutral pictures erotic female nudes whose facial characteristics were computer-modified...

Intrusive memories are a hallmark symptom of posttraumatic stress disorder (PTSD). They reflect excessive and uncontrolled retrieval the traumatic memory. Acute elevations cortisol known to impair already stored memory information. Thus, continuous administration might help in reducing intrusive PTSD. Strong perceptual priming for neutral stimuli associated with "traumatic" context has been shown be one important learning mechanism that leads memories. However, modulating effects have only...

Posttraumatic Stress Disorder (PTSD) is a severe mental disorder characterized by distressing intrusions. Since not all traumatized individuals develop PTSD, it important to understand its underlying risk factors. So far, several psychological and physiological factors have been identified. However, these rarely examined together. An excellent tool assess analogue PTSD in prospective manner the trauma film paradigm. This study relevant 60 healthy participants before, during after...
