We discuss the neuroimaging study (McMillan et al., 2005). According to the authors their results verify a particular computational model of natural language quantifier comprehension posited by several linguists and logicians (see Van Benthem, 1986). We challenge this statement by evoking the computational difference between first-order quantifiers and divisibility quantifiers (see M. Mostowski, 1998). Our observations suggest other studies on quantifier comprehension which can throw more light on the role of working memory in processing quantifiers.
