Du parricide rêvé à l’infanticide réel,ou l’expertise mentale dans tous ses états

The authors describe at length the case of a 33-year-old woman who shot and killed her 9-year-old daughter and attempted suicide immediately afterwards. The judicial inquiry revealed that this infanticidal mother originally intended to kill her own father, who she accused of having sexually abused her in her own childhood and now her daughter, but that unforeseen circumstances changed the mode of operation. She was the subject of seven more or less contradictory psychiatric experts opinions over a period of more than three years before finally being found criminally irresponsible by the court of assizes. She was suffering from delusional psychotic mental disorders at the time of the homicide-suicide. The authors discuss and criticize the conclusions of the experts opinions and instead recommend a multidisciplinary criminological analysis that takes all the objective ans subjective aspects on the case into account.     

Reward bias and lateralization in gambling behavior: behavioral activation system and alpha band analysis

The present research explored the main factors that can influence subjects’ choices in the case of decisions. In order to elucidate the individual differences that influence the decisional processes, making their strategies more or less advantageous, we tested the effect of a reward sensitivity in the behavioral activation system (BAS-Reward) constructed on the ability to distinguish between high- and low-risk decisions. Secondly, the lateralization effect, related to increased activation of the left (BAS-related) hemisphere, was explored. Thirty-one subjects were tested using the Iowa Gambling Task, and the BAS-Reward measure was applied to distinguish between high-BAS and low-BAS groups. Behavioral responses (gain/loss options) and alpha-band modulation were considered. It was found that high-BAS group increased their tendency to opt in favor of the immediate reward (loss strategy) rather than the long-term option (win strategy). Secondly, high-BAS subjects showed an increased left-hemisphere activation in response to losing (with immediate reward) choices in comparison with low-BAS subjects. A “reward bias” effect was supposed to explain both the bad strategy and the unbalanced hemispheric activation for high-BAS and more risk-taking subjects.     

Evaluation of the observer effect on compliance training in adolescents with autism

Three mothers conducted behavioral observations of video clips of a mother conducting compliance training to varying degrees of accuracy. Subsequently, two mothers correctly conducted compliance training and their children emitted compliant behavior. Upon addition of feedback, the third mother correctly implemented compliance training and her child also emitted complaint behavior. Conducting behavioral observations may be a viable and efficient option for training parents to conduct compliance training and, if ineffective, can be supplemented by feedback.     

Using Measures of Readiness to Change in Individuals with Schizophrenia

The literature suggests that substance abuse treatment for schizophrenia patients should consider both the patients' readiness for active treatment and matching phases of intervention with phases of the patient's acceptance of his or her dual problems. This study assessed the suitability of existing measures of “readiness to change” for use with individuals with schizophrenia. Outpatients (n = 39) with a diagnosis of schizophrenia and alcohol and/or drug dependency or abuse were given three measures to assess the stage of readiness to change. Results suggested that there was no agreement between stages defined by the interviewer and stages defined by self-report. This has implications for assessing readiness to change in terms of substance use in a population with schizophrenia.
