Facial expressions of emotions guide social interactions, thus enhancing adaptation and functioning of an individual, and the ability to recognize them could be related to stable personality traits. This research aimed to examine relationship of Big Five personality traits, Dark Triad personality traits, and aggressiveness with the accuracy of recognizing unambiguous and the categorization of ambiguous emotional and neutral facial expressions. Two hundred and seven subjects participated in the study who completed the emotion recognition test, which, besides the standard "prototypical" unambiguous expressions of six basic emotions, also contained ambiguous and neutral facial expressions, as well as series of personality questionnaires: Big Five Inventory, Narcissistic Personality Inventory, Test of Machiavellianism, Self-Report Psychopathy Scale and Aggression Questionnarie. Before examining the effects of personality traits on emotion recognition, general recognition of emotions and patterns of errors were inspected. Results confirmed earlier findings, with the level of accuracy being highest for happy expressions and lowest for fear expressions. Regarding relationship of the personality traits, results showed that openness to experience was associated with recogniton of emotional expressions of fear, more open individuals were more accurate in their recognition. This finding is discussed by account of their aesthetic sensitivity and in the context of frequency-of-occurrence hypothesis. Also, psychopaty was associated with categorization of neutral expressions as emotional expressions of disgust, individuals with a more pronounced psychopaty trait were more prone to categorize neutral expressions as emotional expressions of disgust, which is discussed in the context of their social interactions and within the framework of evolutionary psychology. The relationships of other considered variables did not prove to be significant. Except from empirical contributions, these study findings provide guidelines for practical interventions.
