When Humans and Birds Are Tested on Their Ability to Detect

Multiple Choice

When humans and birds are tested on their ability to detect embedded stimuli,

A) birds do better when the unique region differs by a single feature, whereas humans can solve the problem as easily when one or multiple features are present.
B) birds are more likely to find the unique region when the entropy value of the display is low, whereas entropy value does not affect human detection.
C) birds compare each area with other areas to find the embedded stimulus, whereas humans use a more general strategy of textural roughness.
D) birds and humans perform similarly; both are most successful at finding the embedded region when it contains a unique feature.
