Threat detection plays a vital role in adapting behavior to changing environments. A
fundamental function to improve threat detection is learning to differentiate between stimuli …

Past research on the effects of associative aversive learning on discrimination acuity has
shown mixed results, including increases, decreases, and no changes in discrimination …

Aversive learning is thought to modulate perceptual thresholds, which can lead to
overgeneralization. However, it remains undetermined whether this modulation is domain …

Animal studies of discriminative fear conditioning traditionally use stimuli that are distant in
physical features and thus easily distinguished perceptually. Independently, human studies …

Relying on existing literature to identify suitable techniques for characterizing individual
differences presents practical and methodological challenges. These challenges include the …

Humans can acquire fear through the observation of others'(learning models') threat
responses. These responses can be direct responses to aversive stimuli, or anticipatory …

In classical fear conditioning, neutral conditioned stimuli that have been paired with aversive
physical unconditioned stimuli eventually trigger fear responses. Here, we tested whether …

With practice, humans tend to improve their performance on most tasks. But do such
improvements then generalize to new tasks? Although early work documented primarily task …

Perceptual learning is often orientation and location specific, which may indicate neuronal
plasticity in early visual areas. However, learning specificity diminishes with additional …

Aversive learning normally induces alterations in sensory function as the brain's sensory
systems are tuned to optimize detection and discrimination of threat-predictive stimuli …
