The aim of the present study was to investigate whether chemosensory anxiety signals can activate behavioral withdrawal systems in humans. Twelve male university students donated their axillary sweat in two situations: right before an oral academic examination (anxiety condition) and during ergometric training (exercise condition). Subjective ratings revealed that the odor donors experienced significantly more anxiety and less pleasure during the anxiety condition than during the exercise… Expand
Startle response potentiation to chemosensory anxiety signals in socially anxious individuals.
TLDR
It is concluded that human motor systems automatically adapt to chemosensory stress signals and this adaptation is neither dependent on theGender of the odor donor nor on the gender of the perceiver, but is intensified in socially anxious participants. Expand
Chemosensory anxiety signals prime defensive behavior in prepubertal girls
TLDR
In prepubertal girls, similar to adults, chemosensory anxiety signals prime defensive motor behavior, and this effect appears unrelated to the odorous quality of anxiety sweat, but seems to reflect a specific preparedness to respond to the underlying social alarm signal. Expand
Smelling chemosensory signals of males in anxious versus nonanxious condition increases state anxiety of female subjects.
TLDR
Evidence is given that male anxiety chemosignals compared with neutral chemosignedals are capable of inducing an increased state anxiety in female subjects. Expand
Intensified Neuronal Investment in the Processing of Chemosensory Anxiety Signals in Non-Socially Anxious and Socially Anxious Individuals
TLDR
It is concluded that the processing of chemosensory anxiety signals requires enhanced neuronal energy, and socially anxious individuals show an early processing bias towards social fear signals, resulting in a repression of late attentional stimulus processing. Expand
Induction of Empathy by the Smell of Anxiety
TLDR
The fMRI results (event-related design) show that chemosensory anxiety signals activate brain areas involved in the processing of social emotional stimuli (fusiform gyrus), and in the regulation of empathic feelings (insula, precuneus, cingulate cortex). Expand
Chemosensory signals of competition increase the skin conductance response in humans
TLDR
The current result suggests that chemosensory signals of competition can be communicated between humans, and that they elicit orienting in the perceiving individual. Expand
Chemosensory anxiety cues moderate the experience of social exclusion – an fMRI investigation with Cyberball
TLDR
It is possible that the anxiety signals make it easier for the individuals to detach from the group, pointing to the communicative role of chemosensory anxiety cues in enhancing adjustment mechanisms in light of a distressing situation. Expand
Oxytocin reduces a chemosensory-induced stress bias in social perception
TLDR
A new role for OXT signaling in the modulation of chemosensory communication of stress in humans is revealed and appears to be rooted in a downregulation of stress-induced limbic activations and concomitant strengthening of top-down control descending from the ACC to the fusiform face area. Expand
Effects of Male Anxiety Chemosignals on the Evaluation of Happy Facial Expressions
The communication of chemosensory alarm signals is well explored in mammals. In humans the effects of anxiety substances might seem to be less important due to their high-developed visual system, andExpand
Context counts! social anxiety modulates the processing of fearful faces in the context of chemosensory anxiety signals
TLDR
The current results show that visual and chemosensory information is integrated on virtually all levels of stimulus processing and that socially anxious individuals might be especially sensitive to chemOSensory contextual social information. Expand

Positive emotional priming of facial affect perception in females is diminished by chemosensory anxiety signals.
TLDR
It is discussed whether, in socially relevant ambiguous perceptual conditions, chemosensory signals have a processing advantage and dominate visual signals or whether fear signals in general have a stronger behavioural impact than positive signals. Expand
Emotional qualities of odors and their influence on the startle reflex in humans.
TLDR
Evaluating the emotional effects of positive and negative odorant stimuli found that H2S, a presumed negative foreground stimulus, significantly enhanced the startle-reflex amplitude relative to neutral air stimulation, whereas vanillin, a positive foreground stimuli, tended to reduce the reflex amplitude compared withneutral air stimulation. Expand
Emotion, novelty, and the startle reflex: habituation in humans.
Previous research with both animal and human subjects has shown that startle reflex magnitude is potentiated in an aversive stimulus context, relative to responses elicited in a neutral or appetitiveExpand
The scent of fear.
TLDR
Results show that subjects were able to discriminate between fear and non-fear axillary pads, suggesting that women are indeed able to detect "the scent of fear" and a direct correlation between induced fear, changes in cortisol levels and smell ratings could not be established. Expand
Human Olfactory Communication of Emotion
TLDR
The finding suggests that there is information in human body odors indicative of emotional state and introduces new complexity in how humans perceive and interact. Expand
Alarm pheromone enhances stress-induced hyperthermia in rats
TLDR
It is suggested that an alarm pheromone enhances stress responses of conspecific animals both behaviorally and physiologically, and that these effects are mediated via activation of the accessory olfactory bulb. Expand
Emotion, attention, and the startle reflex.
TLDR
The startle response (an aversive reflex) is enhanced during a fear state and is diminished in a pleasant emotional context and the effect is found when affects are prompted by pictures or memory images, changes appropriately with aversive conditioning, and may be dependent on right-hemisphere processing. Expand
The effects of odors from stressed mice on conspecific behavior
TLDR
Four experiments correlate conspecific reactions to odors from stressed (foot shocked) BALB/cJ mice with the frequency of specific motor activities and taste avoidance and fail to produce conditioned taste aversion, suggesting a sensory specificity in the use of these odors. Expand
Fear-potentiated startle conditioning in humans: explicit and contextual cue conditioning following paired versus unpaired training.
TLDR
It is suggested that paired presentations of a CS and an aversive US result in conditioned fear in response to the CS but little contextual fear, whereas unpaired presentations of the CS and US leads to poor explicit cue conditioning but substantial contextual fear. Expand
Rat's responses to blood and body odors of stressed and non-stressed conspecifics
TLDR
Responses to these odors depend upon the stressor applied to the odor producing rats, and it is concluded that Rats subjected to different stress conditions may change the quality or concentration of the odors they emit and thereby alter the responses of rats receiving the odor. Expand
