Design of odor tasks and overview of main results. (A) After completion of the entry odor task (passive recognition of 4 odors - multiple choice), subjects were asked to assign a set of attributes (odor interpretation) and then to name the respective odorant (odor naming), consecutively for 6 odors. (B) The entry odor task revealed a clear contrast between test results (schizophrenia patients, healthy controls) and theoretical binomial probabilities for guessing subjects. (C) The main findings of the study are summarized. Low interpretation performers (LIP) showed worse reasoning abilities, a more severe psychopathology and emotional processing deficits.
