The visual-manual modality of sign languages renders them a unique test case for language acquisition and processing theories. In this commentary the authors describe evidence from signed languages, and ask whether it is consistent with Ambridge's proposal. The evidence includes recent research on collocations in American Sign Language that reveal collocational frequency effects and patterns that do not constitute syntactic constituents. While these collocations appear to resist fully abstract schematization, further consideration of how speakers create exemplars and how they link exemplar clouds based on tokens and how much abstraction is involved in their creation is warranted.
