influences of animal specie on subject performance. (A) Various classes of animals: mammals, fish, birds and reptiles are represented for color and BW images. Mammals were first sub-divided into two groups, common mammals (Common Mam.) and rare mammals (Rare Mam.), but no significant difference could be shown (see text) so they were grouped together for later analysis. (B) Variation of subject accuracy with time for different classes of images. Accuracy is best for the reptile class. The vertical dotted line at 335 ms indicates the earliest latency at which the reptile category differs from the mammal category. (C) Reaction time distributions for the different classes of images.
