Semantic knowledge influences various higher-order cognitive processes; therefore, it is important to understand how it changes with development. The Match-to-Sample task is perhaps the most common paradigm for studying changes in semantic knowledge over development, yet this paradigm has a number of limitations. Here we provide initial evidence validating a Visual Search paradigm as a measure of semantic knowledge in preschoolers, and discuss the potential of this paradigm to address the limitations posed by the Match-to-Sample task to study semantic knowledge development.
