This preregistered study examines how awareness of stimuli influences neural learning in fear conditioning.

This study investigates the role of contingency awareness in fear conditioning and neural responses.
Recorded electroencephalography during a task involving word and tactile stimuli.
Divided participants into aware and unaware groups based on interviews.
Analyzed neural responses to predictions of unconditioned stimuli (US+ and US−).
The aware group exhibited significant neural learning, indicated by larger stimulus-preceding negativity before US+.
Stronger theta responses to vibrations predicting US+ were found only in the aware group.
Alpha and beta suppressions were greater in the aware group prior to aversive learning.

Pavlov et al. (2025) studied this question.
