When Humans and Birds Are Tested on Their Ability to Detect

question 22

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.
