Byrne & Russon propose an account of imitation that mirrors levels of behavioral organization, but they perpetuate a tendency to dismiss imitation by members of most species as the result of more primitive processes, even though these alternative phenomena are often poorly understood. They argue that the prerequisites to program-level imitation are present in great apes, but the same prerequisites appear to be present in a broad range of species. The distribution of imitative capacity across species may be more limited by research methodology than by cognitive ability.

This study examined the comprehension of English conventional indirect requests by native English speakers and Japanese learners of English. Subjects read stories inducing either a conventional or a literal interpretation of a priming sentence. Reading speeds did not vary as a function of the interpretation. Subsequent target sentences that paraphrased either the literal or the conventional interpretation of the prime sentence were read more quickly when they paraphrased a conventional interpretation of the sentence than when they paraphrased a literal interpretation. Target sentences were also read more quickly if they paraphrased the interpretation induced by the context than if they did not match. The results suggest that both native and nonnative speakers process both meanings of an ambiguous conventional request.
