As a relevant test case, weemployed complex number terms such as ‘twenty-three’,where one number termis not a quantifier of the otherbut rather, the two terms form a type of complex concept. In a number naming paradigm, participants viewedrows of numbers and depending on task instruction, named them as complex number terms (‘twenty-three’),
numerical quantifications (‘two threes’), adjectival modifications (‘blue threes’) or non-combinatory lists(e.g., ‘two, three’).
