In terms of consumer behavior, when people are presented with two options, they most often go for the cheapest item. Yet, when a third, middle-priced item is added, people are more likely to opt for a more expensive item, believing it to be a better bargain. This is called the decoy effect. A new study reports bats, like humans, are prone to fall for the decoy effect.
Just like human babies, the young Saccopteryx bilineata bat babbles as part of its initial language learning phase.
