In contrast to this conception, it is argued that this concept should rather be understood as part of a certain kind of grounding explanations of the radio listener's understanding. This particular conception is based on the distinction between `specification' and `implementation' as found in the theory of abstract data types. Its application to the field of spatial concepts leads to a computational system (ANTLIMA) which exemplifies how the expression `mental image' could be used while explaining a speaker's ability to control the resolvability of ambiguities in an objective report of what the speaker sees. %K spatial reasoning, mental images, semantics of locative expressions %P 107-136 %E Klaus Sachs-Hombach %D 1995 %I Rodopi, Amsterdam %L cogprints1517
