Conditioned inhibition (CI) has been difficult to establish paradigm in human study. However, these difficulties have been overcome. It has been found that CI is of great help in the study of disorders such as schizophrenia or people with schizotypal traits in which inhibitory cognitive mechanisms are deficient. In this context, the present research has as main objective to characterize behavioral markers through associative learning techniques in experiments with patients suffering from schizophrenia and describe associative learning in the group of patients with schizophrenia and in the group of participants without it. For this, by means of a computer exercise, conditioned excitation and inhibition in the same discrimination procedure was measured. CI was measured through a ratio score comparing the degree to which the inhibitory stimulus and the neutral stimulus reduced the conditioned response to the excitatory signal. Therefore, a lower ratio score would indicate a greater inhibitory learning. However, it was observed that there were no significant differences between the group of patients with schizophrenia and participants without schizophrenia. In addition, neither of the two groups achieved discrimination between reinforced and unreinforced stimuli. What could mean that the type of image that can be used as EI was not the appropriate or neutral for the chosen sample.
