%X there are many ways in which semantic organization can be assessed. the methods usually used are useful in many ways but fail to provide the possibility to visualise the configuration of a semantic network corresponding to a certain group of concepts and to make qualitative and quantitative comparisons between different networks. the aim of the current research is to show the application of a semantic distance judgment method to stroke patients. this method is called distsem and it was build on the basis of spreading activation theory (collins & loftus, 1975). it allows obtaining the configuration of a semantic network according to the semantic distance judgment realized by the individuals between pairs of concepts of different and equal semantic category given by the examiner. the method has been administered to 30 stroke patients and 30 healthy controls. in the current paper, the response patterns of the patients are analyzed quantitatively and qualitatively and comparisons are made with the production of healthy controls. in the first place, all the matrixes were correlated with an interjudges matrix and the results show that strokepatients obtained significantly lower correlations than controls. in the second place, the matrixes of the stroke patients were correlated with a matrix that represented the mode of the estimations made by the group of healthy subjects. there were found two atypical groups. on the one hand, there was a group of patients that found scarce relations between concepts. on the other hand, there was another group that found a great number of relations between concepts, including relations between concepts that were not from the same semantic category. this data can be interpreted in light of collins and loftus theory as a failure of the spreading of the activation. some patients seem to fail in the searching process within the network, particularly in the control of the spread of the activation necessary to look for the similarities requeste
