Jihyun Hwang will be available during this time. I would be happy to give a brief presentation or answer
any questions. If you cannot attend our virtual presentation
and would like to know more, we can talk via OSF comments (click the icon at top right corner) or email (jihyunhwang@umass.edu).
*Abstract:* Complex numerals are constructed by recursive Merge operations
between Digits (one to nine) and Multipliers. Our hypothesis that children
understand the syntactic structure of complex numerals for acquiring entire
number concepts was addressed by devising a number word comparison task.
Children (4-6 yrs) chose the larger number after hearing two single digits
or complex numerals. We found that (1) children correctly compared complex
numerals beyond their counting range; (2) the structure of complex
numerals, not non-numerical constituents, disrupted children’s ability to
compare the targeted digits. These results support that children understand
the compositionality of complex numerals prior to knowing their meaning.
