DAMM is a Dynamic Allocation Model of Meaning used to simulate the und
erstanding of running situations by modelling the categorical allocati
on and the changes of allocation of objects. Two of the mechanisms of
the model are (a) an integration mechanism for categorical allocations
and (b) a mechanism for the attentional shift of category. When appli
ed to the understanding of texts that report verbal jokes, composed of
two successive Interpretation and Reinterpretation Sentences both rel
ated to a polysemous term, the first mechanism predicts a longer respo
nse time for understanding the Reinterpretation Sentence. The second m
echanism predicts a diminution of the response time of the Reinterpret
ation Sentence when the category allowed for Reinterpretation was pre-
cued. Experimental results are compatible with the predictions of this
general model of understanding, both on the effect of the distance be
tween categories and on the effect of having precued the category allo
wed for Reinterpretation.
