Virtual reality (VR) has become a popular approach to study human behavior in fire.The present position paper analyses Strengths, Weaknesses, Opportunities, and Threats (SWOT) of VR as research tool for fire.Virtual environments provide maximum experimental control, are easy replicate, have relatively high ecological validity, allow safe occupant scenarios that otherwise would be too dangerous.Lower validity compared field studies, ergonomic aspects, technical limitations the main weaknesses...
Abstract Facial muscular reactions to avatars' static (neutral, happy, angry) and dynamic (morphs developing from neutral happy or facial expressions, presented for 1 s each, were investigated in 48 participants. Dynamic expressions led better recognition rates higher intensity realism ratings. Angry rated as more intense than expressions. EMG recordings indicated emotion‐specific avatars reflected increased M. zygomaticus major decreased corrugator supercilii tension, with stronger compared...
The main purpose of this study was to examine if disgust toward unpalatable foods would be reduced among food-deprived subjects and attenuation occur automatically even under moderate levels food deprivation. Subjects were either satiated or deprived for 15 hours electromyographic activity recorded at the levator muscle region while they watching pictures palatable versus foods, positive disgust-related control pictures. For purposes, subjects' zygomaticus corrugator muscles also recorded....
Anxiety is supposed to enhance the processing of threatening information. Here, we investigated cortical angry faces during anticipated public speaking. To elicit anxiety, a group participants was told that they would have perform speech. As control condition, another write short essay. During anticipation these tasks, saw facial expressions (angry, happy, and neutral) while electroencephalogram recorded. Event-related potential analysis revealed larger N170 amplitudes for compared happy...
Numerous studies have shown that humans automatically react with congruent facial reactions, i.e., mimicry, when seeing a vis-á-vis' expressions. The current experiment is the first investigating neuronal structures responsible for differences in occurrence of such mimicry reactions by simultaneously measuring BOLD and EMG an MRI scanner. Therefore, 20 female students viewed emotional expressions (happy, sad, angry) male avatar characters. During picture presentation, signal as well M....
Our first impression of others is highly influenced by their facial appearance. However, the perception and evaluation faces not only guided internal features such as expressions, but also dependent on contextual information secondhand (verbal descriptions) about target person. To investigate time course influences cortical face processing, event-related brain potentials were investigated in response to neutral faces, which preceded brief verbal descriptions containing cues affective valence...
Thigmotaxis refers to a specific behavior of animals (i.e., stay close walls when exploring an open space). Such can be assessed with the field test (OFT), which is well-established indicator animal fear. The detection similar in humans may verify translational validity this paradigm. Enhanced thigmotaxis related anxiety suggest relevance such for disorders, especially agoraphobia.A global positioning system was used analyze 16 patients agoraphobia and 18 healthy individuals risk high...
To investigate whether subliminally priming for competition influences facial reactions to emotional displays, 49 participants were either primed or neutrally primed. Thereafter, they viewed computer generated avatar faces with happy, neutral, and sad expressions while Corrugator supercilii Zygomaticus major recorded. Results revealed mimicry happy in the group but not group. Furthermore, subliminal enhanced activity after an initial relaxation viewing faces. An impression formation task...
Abstract In this study we investigated whether event‐related near‐infrared spectroscopy (NIRS) is suitable to measure changes in brain activation of the occipital cortex modulated by emotional content visual stimuli. As found a previous pilot that only positive but not negative stimuli differ from neutral (with respect oxygenated haemoglobin), now measured EEG potentials and NIRS simultaneously during same session. Thereby, could evaluate subjects ( n = 16) processed as well similar way....
Perception and evaluation of facial expressions are known to be heavily modulated by emotional features contextual information. Such effects, however, might also driven non-emotional aspects information, an interaction factors, the observers' inherent traits. Therefore, we sought assess whether information about self-reference in addition valence influences neural processing neutral faces. Furthermore, investigated social anxiety moderates these effects. In present functional magnetic...
