dc.description.abstract In a replication and extension of a study conducted by Sauteraud, Cottraux, Michel, Henaff and Bouvard (1995), 17 obsessive-compulsive (OCD) subjects, 10 panic disorder (PD) control subjects and 15 healthy control subjects were compared to each other on three lexical decision tasks. Subjects were requested to distinguish real (neutral, obsessive and responsibility) words from pseudo-words, and the response latencies and number of errors were measured. Contrary to the Sauteraud et al. findings, a taboo effect for obsessive and responsibility words was not found; OCD subjects were not significantly slower than PD or healthy controls in the processing of obsessive words, or pseudo-words presented in the same sub-test as obsessive words. On the contrary, a trend towards slightly faster response times to obsessive and responsibility words was noted in all the subjects, particularly OCD and PD subjects, although this trend did not attain significance. The results obtained do not contradict cognitive models of the anxiety disorders, but they do highlight research difficulties and ambiguities in this area. The results are discussed with respect to innovations made in the present study (the inclusion of a PD control group, the controlling for word frequency and length, and the randomisation of the order of presentation of the sub-tests), and weaknesses of the present study (sample size, stimuli presentation, lack of control for emotional content, and a lack of control for subject mood and defensiveness). The need for more specific, tightly controlled research in this complicated and expanding area is highlighted. en
