*Abstract:* Psychopathy is described as a personality disorder associated with affective, interpersonal and behavioral deficits such as lack of empathy or remorse, manipulation and antisocial behavior. The study of facial expressions of emotions processing in psychopathy is a common theme, as an indicator and /or justification of the affective and relational deficits. However, this research did not analyze facial processing as a non-linear functioning. Thus, this paper seeks to explore the process of emotional and perceptual categorization reminiscence in the higher prevalence of psychopathic personality traits. For this purpose, the participants (*n *= 29) were asked to do an identification task of facial stimuli arranged in morphs, i.e. facial expressions organized in a continua (frames)that will progressively changing from one emotional category to another, or randomly presented. The categories used were emotional Happiness, Sadness, Fear and Anger. The hypotheses developed previewed this perceptual reminiscence: (1) psychopathy score is associated with a more salient hysteresis effect; (2) psychopathy score is related with a delay in the detection of Fear comparably to other emotional categories. The results lead to the presence of a relationship between total psychopathy scores and the need for more frames to detect Fear when preceded by Anger’s visualization, which represents a reminiscence of the perceived Anger. Also analyzed, the effects of each subscale of psychopathy (Boldness, Meanness and Disinhibition), the Boldness score showed a positive correlation with retention of Anger and a delayed detection of Sadness, and a negative correlation with Happiness detection after seeing Anger. Thus, the results suggest differences in emotional processing within the increase of some traits psychopathic, especially in the sense of rigidity in emotional detection under the effect of a previous perception and the use of superior and cognitive mechanisms in this process, culminating in a more salient hysteresis effect.
