Figure 5. A General Linear Model was run with age, sex, adjective order and item type as Nested categorical factors into image category (single or double).

The effect of age on the correct identification of aposematic signals in schoolchildren in the case of single and double item images is plotted (F_{16, 1321} = 2.76, P < 0.001). Very young children “incorrectly” identified aposematic signals more often than older children in double item images, but not in single item images. The graph highlights the importance of context in aposematic signal interpretation in children of all ages: percentages of correct identification of aposematic signals were consistently higher with double item images than with single item images.
