patients. Yet, most of this research has focused on cognitive processes and outcomes whereas research on cognitive structures and propositions in psychoses has been less common. A theoretical framework to analyze people's worldviews is that of the beliefs in the just world (BJW). According to this theory, people are motivated to believe in a just world where every one generally gets what they deserve. Personal BJW (BJW-P) implies that events in one's own life are just. On the other hand, general BJW (BJW-G) reflects the belief that, basically, the world is a just place. In paranoid patients, Valiente et al. (to be submitted) have found that people with persecutory beliefs show significantly weaker BJW-P than non- psychiatric controls whereas there are no significant differences in BJW-G. Lower BJW-P have important behavioural and emotional consequences. We argue that BJW are related to psychosocial and traumatic experiences. Likewise, Janoff- Bulman (1992) found that people, who had experienced a traumatic event many years ago, hold more negative worldviews. Thus, the goal of this study was to examine how the different types of trauma are linked to BJW in paranoia. Methods: 39 current persecutory beliefs patients and 42 non psychiatrics participants were assessed with Beliefs in a Just World Scale – General (BJW-G), Belief in a Just World Scale- Personal (BJW- P). The total number of traumas was assessed by Trauma History Screen (THS) included natural disasters, dead, separation, negli- gence and interpersonal traumas as physical and sexual abuse and psychological abuse. The number of interpersonal traumas was assessed by Trauma History Screen (THS) included only physical and sexual abuse and psychological abuse. Stepwise multiple regres- sions were used to evaluate the capacity of different types of trauma to explain BJW. Results: Our results showed that the total number of traumas, and interpersonal trauma in particular, were negatively related to BJW-P in paranoid patients (r =-. 31; r = -.39). Interpersonal trauma explained 24% of the variance in BJW-P after controlling for demographic characteristics [ΔR 2 = 0.24, ΔF (1,34)= 4.80, p =.035], however accumulated trauma (including all types of trauma) did not explained a significant variance of BJW [ΔR 2 = 0.20, ΔF (1,34)=3.15, p =.084]. For the control group, interpersonal trauma was positively related to BJW-P (r =. 30), but regression analyses didn't reach significance [ΔR 2 = 0.20, ΔF (1,39) = 3.75, p = .060]. Discussion: In general, our data support the relevance of the environmental factors to explain the aetiology cognitive structures and propositions of persecutory delusions. These results indicated that interpersonal trauma in particular, but not the accumulative effect of all other traumas, is linked with low perception of personal justice. Paradoxically, there seems to be a opposite tendency for non-psychiatric controls. The implications for clinical work and further research are discussed. doi:10.1016/j.schres.2010.02.1006 Poster 246 TOLERANCE OF UNFAIRNESS AND COSTLY PUNISHMENT IN SCHIZOPHRENIA Julia Wischniewski, Martin Brüne LWL-Universitätsklinik der Ruhr-Uni-Bochum, Psychiatrie, Psychother- apie, Psychosomatik und Präventivmedizin Bochum, NRW, Germany Background: Humans possess evolved cognitive and emotional biases that guide an individual's actual behaviour in terms of cooperation, defection or punishment of unfair behaviour. Empirical evidence suggests that a neural network comprising parts of the frontal lobe as well as limbic structures is involved in economic decision-making. This network greatly overlaps with those brain structures that are known to be dysfunctional in schizophrenia. Accordingly, we hypothesised that patients with schizophrenia would differ from controls in performance on tasks involving economic decision-making. Methods: 25 in-patients with schizophrenia (SCHIZ) (7 female, 18 male) were compared with a group of 25 healthy controls (NC), on performance in an Ultimatum Game (UG), where participants had the role of the recipient, and in a Dictator Game with Punishment (DGP), where participants took the role of a third-party player equipped with the ability to punish a dictator for being unfair. Notice that punishment in the DGP is costly for the punisher. Patients' mean-age was 32.0 (SD ± 6.5), with a verbal IQ (according to the MWT-B a verbal intelligence test) of 101. The control group did not differ significantly from the patient group with a mean age of 32.9 (SD±6.9) and a verbal IQ of 107. Subjects in both groups had an educational level of 10 years of education as minimum. Patients' psychopathology was measured using the Positive and Negative Syndrome Scale. In addition, sensitivity towards injustice we measured using the Justice Sensitivity Scale, comprising three different perspectives (victim, observer, perpetrator). Subject's ability to make inferences about another person's state of mind was tested by a computer version of the Reading Mind In The Eyes Test. Results: Acceptance rate of unfair offers in the UG was significantly higher in the patient group compared to controls, but both groups' acceptance rates decline with the degree of unfairness of the offers. In the DGP, the punishment-investment by the third-party increased with the degree of unfairness of the proposed offer in both groups at a comparable level. Both groups tended to induce equity between the dictator and the recipient. Regarding the differences in justice sensitivity there were no significant differences between the groups. Looking at the victim perceptive and the perpetrator perspective according to the justice sensitivity scale the SCHIZ group scored even marginally significantly higher than the NC. Acceptance rate of offers in the 7:3 split-condition correlated significantly with scores on the perpetrator perspective of the justice sensitivity scale in a negative way in the SCHIZ group but not in the NC. There were no differences in empathic perspective taking according to the Reading Mind In The Eyes Test. Discussion: Patients with SCHIZ do not behave profoundly different from healthy controls as one would expect according to their as- sumed malfunctioning in theory of mind abilities and difficulties in social interactions. Notwithstanding patients with SCHIZ seem to be less sensitive towards the recognition of unfairness according to the results from the UG by accepting significantly more unfair offers. The fact that the patient group punishes unequal shares analogous to the NC and feel comparably concerned about injustice towards another person lead to the assumption that patients with SCHIZ are still capable of empathising with others. doi:10.1016/j.schres.2010.02.1007 Poster 247 FACIAL AFFECT RECOGNITION IN REMITTED PATIENTS WITH SCHIZOPHRENIA AND BIPOLAR DISORDER I Nursen Yalcin 1 , Alex Hofer 1 , Susanne Baumgartner 1 , Cord Benecke 2 , Falko Biedermann 1 , Eberhard Deisenhammer 3 , Armand Hausmann 3 , Christine Hörtnagl 3 , Georg Kemmler 1,3 , Moritz Muehlbacher 4 , Georg Schwitzer 3 , Wolfgang Fleischhacker 1 1 Medical University Innsbruck, Biological Psychiatry Division, In- nsbruck, Tyrol, Austria; 2 University of Innsbruck, Institute for Psychol- Abstracts 523
