Cook and Mineka found that rhesus monkeys could learn to be afraid of fear-relevant stimuli (toy snakes and crocodiles) but not fear-irrelevant stimuli (flowers and a toy rabbit). Because snakes and crocodiles have particular perceptual characteristics, this finding supports the idea of preparedness, and so offers support for Bennett Levy's findings from their research as they found that snakes were rated as fearful (1.55) compared to rabbits (1.02) 

Ohman and Soares found that participants could be conditioned more rapidly to electric shocks paired with fear-relevant stimuli than to fear irrelevant stimuli. The fear relevant stimuli chosen satisfy the requirements of both the discrepancy and the aversive properties
