Theories of analogical thinking have differed
in the roles they ascribe to processing goals as a
source of constraint on analogical mappings. W e
report an experiment that examines the impact of
processing goals on subjects' mappings in (a) a
task involving generation of plot extensions for
soap opera scripts, and (b) an explicit m o p i n g task
based on characters in the scripts. The scripts were
written so that the mappings for central characters
were four-ways ambiguous. Manipulations of
subjects' processing goals influenced their preferred
m£q)pings, both in the plot-extension and mapping
tasks. In the latter task, goal-irrelevant information
contributed to the resolution of m ^ p i n g s that were
ambiguous on the basis of goal-relevant
information alone. T h e qualitative pattern of
results was successfully simulated using A C M E , a
constraint-satisfaction model of mapping, in which
processing goals are assumed to control an
inhibitory process of selective attention.
Processing goals attenuate the activation level of
goal-irrelevant information, reducing or even
eliminating its impact on mapping decisions.
