Previous evidence has shown that pseudowords made up of real morphemes take more time to process and generate more errors than pseudowords without morphemes in a lexical decision task. The explanation for these results is controversial because two possible arguments may be posited; the first is related to the morphological composition of the stimuli, and the second is related to the larger semantic interpretability of pseudowords with morphemes in comparison with pseudowords without morphemes (a semantic-based explanation). To disentangle this issue, we conducted an experiment with 92 children and 42 adults. For this purpose, a lexical decision task was implemented, controlling for semantic interpretability while manipulating the morphological status of pseudowords. The results show that the morphological composition of pseudowords generates larger latencies and more errors than pseudowords without morphemes, thereby corroborating that morphemes are activated during pseudoword processing even in the case of young readers.
