N2  - We examined whether perception of a threatening object - a spider - was more accurate than of a non-threatening object. An accurate perception could promote better survival than a biased perception. However, if biases encourage faster responses and more appropriate behaviors, then under the right circumstances, perceptual biases could promote better survival. We found that spiders appeared to be moving faster than balls and ladybugs. Furthermore, the perceiver's ability to act on the object also influenced perceived speed: the object looked faster when it was more difficult to block. Both effects - the threat of the object and the perceiver's blocking abilities - acted independently from each other. The results suggest effects of multiple types of affordances on perception of speed.<p />  <p>Language: en</p>
