Changes to animals and people are detected faster and more accurately than changes to plants and artifacts. Graphs show proportion of changes detected as a function of time and semantic category. (Inset) Mean RT for each category (people, animals, plants, moveable/manipulable artifacts, and fixed artifacts). (A) Results for Exp 1. Animate targets: RT M = 3,034 msec (SD, 882), hit rate M = 89.8% (SD, 7.4). Inanimate targets: RT M = 4,772 msec (SD, 1,404), hit rate M = 64.9% (SD, 15.7). (B) Results for Exp 2. Animate targets: RT M = 3,346 (SD, 893), hit rate M = 88.7% (SD, 8.0). Inanimate RT M = 4,996 (SD, 1,284), hit rate M = 67.5% (SD, 16.5). (C) Results for Exp 5. RT: animate M = 2,661 msec (SD, 770). Hit rate, animate vs. vehicle: 90.6% (SD, 7.8) vs. 63.5% (SD, 18.8), P = 10−15.
