Studies between disordered personality and the Big-Five or the Alternative Five-Factor model of normal personality have consistently shown four higher traits. The fifth higher trait, relating to Openness to Experience or Impulsive Sensation Seeking was less supported. The culture-free Nonverbal Personality Questionnaire (NPQ) might help us to characterise the fifth higher trait. We therefore tried the Dimensional Assessment of Personality Pathology (DAPP), the NEO-Personality Inventory-Revised (NEO-PI-R), the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) and the NPQ in 253 healthy participants. Our results yielded five factors, four of which resembled the previous ones. The fifth one, namely Peculiarity Seeking, was defined by NPQ and NEO-PI-R Openness to Experience, ZKPQ Impulsive Sensation Seeking and DAPP Stimulus Seeking. Whether the fifth factor is linked to the schizotypal personality disorder as proposed remains unanswered. © 2012 Elsevier Ireland Ltd. Source

Objective: To study the contribution of executive function to abnormal recognition of facial expressions of emotion in schizophrenia patients. Methods: Abnormal recognition of facial expressions of emotion was assayed according to Japanese and Caucasian facial expressions of emotion (JACFEE), Wisconsin card sorting test (WCST), positive and negative symptom scale, and Hamilton anxiety and depression scale, respectively, in 88 paranoid schizophrenia patients and 75 healthy volunteers. Results: Patients scored higher on the Positive and Negative Symptom Scale and the Hamilton Anxiety and Depression Scales, displayed lower JACFEE recognition accuracies and poorer WCST performances. The JACFEE recognition accuracy of contempt and disgust was negatively correlated with the negative symptom scale score while the recognition accuracy of fear was positively with the positive symptom scale score and the recognition accuracy of surprise was negatively with the general psychopathology score in patients. Moreover, the WCST could predict the JACFEE recognition accuracy of contempt, disgust, and sadness in patients, and the perseverative errors negatively predicted the recognition accuracy of sadness in healthy volunteers. The JACFEE recognition accuracy of sadness could predict the WCST categories in paranoid schizophrenia patients. Conclusion: Recognition accuracy of social-/moral emotions, such as contempt, disgust and sadness is related to the executive function in paranoid schizophrenia patients, especially when regarding sadness. © 2012 The Editorial Board of Biomedical and Environmental Sciences.

Aims of the study: Previous studies have shown that event-related potentials (ERPs) are modulated by anxiety or psychopathic personality traits. Therefore, we hypothesized that the automatic processing of facial expressions of emotions (FEE) is also correlated with related disordered personality traits. Methods: Thirty-seven healthy volunteers underwent both an "oddball" ERP recording to facial expressions of Anger, Happiness, Sadness, and Neutral, and a test of the Dimensional Assessment of Personality Pathology (DAPP). Results: Mean reaction time was longer in response to anger than to other facial expressions. Facial expressions of Anger, Happiness and Sadness did not affect N1 (N170). By contrast, Happiness elicited a delayed P2, Anger elicited both a smaller N2 and a delayed P3b, and both Happiness and Anger elicited a P3b of higher amplitude. In addition, P3a latencies to Happiness were negatively correlated with DAPP Identity problems, and P3b latencies to Happiness were negatively correlated with DAPP Stimulus seeking, Callousness, Passive aggressivity, and Narcissism. Conclusion: Our study demonstrates that Anger implicitly captures attentional resources, and Happiness triggers more facilitated processing in individuals with dissocial traits. © 2012 Elsevier Masson SAS.
