Behavioral results in object tasks when both target and distractor were either congruent (C, light) or incongruent (nC, dark).

<p>(A) SRT distributions in the animal task show a higher peak of correct responses (thick lines) and a lower peak of incorrect responses (thin lines) when the context is congruent (vs. incongruent). A c2 test computed on Hits minus FA distributions revealed a difference between congruent and non-congruent responses starting at 160 ms indicated by the grey thick vertical line.(B) Accuracy as a function of median SRT shows a strong congruency effect in the animal task, an effect that is not seen in the vehicle task. Animals in congruent natural contexts are detected more accurately and faster than in incongruent manmade contexts.
