Three experiments tested a model of question answering called WHEN, wh
ich explains the answer descriptions that are generated when adults an
swer when questions (Golding, Magliano, & Hemphill, 1992). College stu
dents answered questions about future events in the context of a 12-mo
nth calendar year. The WHEN model specifies how the time of the future
event is expressed as a function of the temporal interval between the
present point in time and the time of a future event (1-90 days away)
. The answers included generative descriptions (e.g., ''next week on W
ednesday'') and specific dates (e.g., ''August 13''). The answers syst
ematically varied as a function of temporal interval in a fashion that
supported most of the production rules of the WHEN model.
