Labels are often advantageous for category learning. However, this may not be true for children as they learn subordinate, fine-grained object categories. In preparation for future research on subordinate category learning in children, we aimed to refine a procedure investigating the label advantage during subordinate category learning in adults. Thus, we conducted an online replication of Experiment 2 from Lupyan, Rakison, & McClelland (2007), which compares category learning under an auditory or written label condition versus a no label and non-linguistic cue condition in adults. We failed to replicate the key result, that those who received labels learned the categories faster.
