The impact of meaning and dimensionality on the accuracy of children's copying

Studies of intellectual realism have shown that children aged 7 to 9 copy a line drawing of a cube less accurately than a non‐object pattern composed of the same lines ( Phillips, Hobbs, & Pratt, 1978 ). However, it remains unclear whether performance is worse on the cube because it is a three‐dimensional representation, or because it is a meaningful object, or both. The accuracy with which twenty 7‐year‐old and twenty 9‐year‐old children reproduced 16 line drawings of two‐dimensional and three‐dimensional objects and non‐objects was assessed. Older children copied all types of drawing more accurately than younger participants, and children of all ages copied two‐dimensional drawings more accurately than three‐dimensional. Meaningfulness interacted with dimensionality for ratings of drawing accuracy, assisting the copying of two‐dimensional drawings, but having no impact on the copying of three‐dimensional drawings. For an objective measure based on position, length, and orientation of line, meaningfulness interacted with age group, being beneficial for 7‐ but not 9‐year‐olds. Overall, the results imply that, contrary to previous suggestions, meaningfulness can actually be beneficial to copying.
