Objective To investigate the application value of eye tracking in lie detection. Methods The 40 subjects were randomly divided into two groups. The pupil diameter, fixation duration, points of fixation and blink frequency of the subjects in the experimental group in observing target stimulation and non-target stimulation were recorded with eye tracker after they accomplished the mock crime. The eye movement parameters of subjects in the control group were directly collected. The differences in eye movement parameters of the experimental group and the control group in observing target stimulation and non-target stimulation were analyzed by t-test. Pearson coefficient analysis of correlation between eye movement parameters that had differences was conducted. The effectiveness of eye movement parameters to distinguish between the experimental group and the control group was calculated by the receiver operator characteristic (ROC) curve. Results Participants from the experimental group had shorter average pupil diameter, longer average fixation duration and fewer fixation points (P<0.05), but the differences in blink frequency had no statistical significance. The differences in the above indicators of the control group in observing target stimulation and non-target stimulation had no statistical significance. The average fixation duration showed a negative correlation with fixation points (r=-0.255, P<0.05); the average fixation duration showed a negative correlation with average pupil diameter (r=-0.218, P<0.05); the fixation points showed a positive correlation with average pupil diameter (r=0.09, P<0.05). The area under the curve of average pupil diameter, average fixation duration and fixation points was 0.603, 0.621 and 0.580, respectively. Conclusion The average pupil diameter, average fixation duration and fixation points obtained by the eye tracker under laboratory conditions can be used to detect lies.

OBJECTIVE@#To analyze the characteristics of recidivism in patients with mental disorders, including criminology, clinic and guardianship, in order to provide references for preventing recidivism.@*METHODS@#Using the self-designed questionnaire, 156 psychotic patients who had repeated crimes were appraised by West China Forensic Science Center of Sichuan University from 2007 to 2011 and the data were collected and analyzed.@*RESULTS@#In the majority of these cases, patients were male, 26-45 years old, junior high school or below diploma, unmarried, and farmers or jobless. Each patient broke law 3.26 times on average. The main crimes were intentional injury (34.6%) and murder (15.7%). Within 5 years after diagnosis with mental disorder, 56.4% of the patients committed first crime. Within 1 year after the first time breaking the law, 55.8% of them repeated crimes. The diagnoses of schizophrenia (63.5%) were in the majority. The assessment results were mostly irresponsibility (61.5%). Among the patients, 44.9% of them didn't receive treatment while 34.6% of them were out of supervision. After the first crime, 66.1% of them didn't receive criminal prosecution while only 7.1% of them went through the appraisement of forensic psychiatry.@*CONCLUSION@#Most of the patients had low education and low income. Meanwhile, low outpatient rate and pool supervision occurred in this special crowd. A good system for care and treatment of these mental patients should be built to prevent them from recidivism.

OBJECTIVE@#To explore the value of Modified Overt Aggression Scales (MOAS) in assessing risk behavior of patients with mental illness.@*METHODS@#Four hundred and ninety patients, who were from three mental health institutions (Refined Control Ward in Ankang Hospital, Mental Health Center of West China Hospital, Relief Ward in De Kang Hospital) belong to public security, health and civil system respectively, were evaluated with MOAS.@*RESULTS@#Three hundred and thirteen patients did not have dangerous behavior, but 177 patients did (99 aggression, 78 violence). The descending order of risk behavior in patients with mental illness were Refined Control Ward in Ankang Hospital, Mental Health Center of West China Hospital, Relief Ward in De Kang Hospital. Physical and total aggression scores were higher in Refined Control Ward in Ankang Hospital than that in other two hospitals (P < 0.05). Autoaggression score in Mental Health Center of West China Hospital was higher than that in other two hospitals (P < 0.05). Physical and total aggression scores in male were higher than that in female (P < 0.05). Autoaggression score in female was higher than that in male (P < 0.05). Score of every single item and total score were higher in violent and aggressive group than that in non dangerous behavior group (P < 0.05). Physical and total aggression scores in violent group were higher than that in aggressive group (P < 0.05).@*CONCLUSION@#The proportion, type and degree of risk behaviors in three mental health institutions are different and the type of risk behavior has gender difference.
