The study found that monkeys can localize stimuli they do not perceive, similar to humans, who can also locate and side-step objects in their peripheral vision. Monkeys performed tasks accurately when stimuli were unmasked, but still localized targets at masking levels for which they reported no target had been presented.
A new Cornell University study reveals that consumers are willing to pay more for products labeled as 'free of' certain ingredients. When provided with more information about the risks associated with those ingredients, consumers become even more confident in their purchasing decisions and value the product more.
