Toddlers' symbolic understanding of iconic models was assessed through 2 comprehension‐based tasks: 1 based on looking and 1 requiring manual selection of the target object. Toddlers received either iconic models or photographs of models as the symbolic referent. Overall, 18‐month‐olds performed poorly, and both 22‐and 26‐month‐olds performed relatively well across tasks. Contrary to expectations that the 2 tasks would impose different levels of attentional demands, performance was relatively consistent across tasks. Vocabulary size was significantly related to performance, even when the effects of age were controlled. Relations between model comprehension and more sophisticated manifestations of symbolic comprehension are considered.
