“…For example, when interviewers ask children nonsense questions or unanswerable questions (i.e., questions about event details the children have not experienced, and therefore have no correct answers), many children attempt to answer those questions rather than saying "I don't know," even though they lack the required information or the questions do not make sense (Waterman et al, 2000(Waterman et al, , 2001. Although classic studies found that children attempt to answer nearly all unanswerable questions asked of them (Hughes & Grieve, 1980;Pratt, 1990), more recent research has demonstrated that this is particularly true for closed (yes-no) questions, as opposed to more open questions (wh-questions; Gee, Gregory, & Pipe, 1999;Waterman et al, 2000;Waterman, Blades, & Spencer, 2004). In one such study, children answered the large majority of nonsensical closed questions, although they judged 92% of these questions to be "silly questions" during a later session (Waterman et al, 2000).…”
