Sensory information can both impair and enhance low-level visual feature processing, and this can be significantly modulated depending on the whether this information matches the visual sensory modality. Emotionally significant visual and auditory stimuli can have opposing effects on attention.

To date, no study has directly compared how emotionally salient information presented to different sensory modalities can affect low-level vision. Using Gabor patches of differing contrasts to measure the threshold of visual perception, we hypothesized that …
