Acquired fear responses often generalize from conditioned stimuli (CS) towards perceptually
similar, but harmless generalization stimuli (GS). Knowledge on similarities between CS and …

Anxiety states are characterized by attentional biases to threat and increased early brain
responses to potentially threat signaling stimuli. How such stimuli are processed further …

Stimuli that signal threat show considerable variability in the extents to which they enhance
behavior, even among healthy individuals. However, the neural underpinning of this …

We tested the proposal that signals of potential threat are given precedence over positive
and neutral signals, reflected in earlier and more pronounced changes in neural activity. The …

Environmental conditions bias our perception of other peoples' facial emotions. This
becomes quite relevant in potentially threatening situations, when a fellow's facial …

The generalization of conditioned fear responses has been shown to decrease as a function
of perceptual similarity. However, generalization may also extend beyond the perceptual …

Debate continues as to the automaticity of the amygdala's response to threat. Accounts
taking a strong automaticity line suggest that the amygdala's response to threat is both …

Expectancies strongly shape our perception of the world and preconceptions about stimulus
characteristics can even bias the sensory system for illusory percepts. Here we assessed …

Processing of unattended threat-related stimuli, such as fearful faces, has been previously
examined using group functional magnetic resonance (fMRI) approaches. However, the …

Facial expressions of fear are universally recognized signals of potential threat. Humans
may have evolved specialized neural systems for responding to fear in the absence of …
