Politique institutionnelle de libération : identification des individus dangereux. Une revue de la littérature

Follow-up studies of the physical dangerousness of men released from correctional institutions, mental hospitals and special security psychiatric institutions have indicated that we cannot as yet predict with an acceptable degree of accuracy which men will be dangerous upon release. Because of the methodological and conceptual weaknesses of these predictive studies and their lack of success, as well as the practical difficulties which would arise from not attempting to select nondangerous men for release, a new approach to the problem of prediction is required. Such an approach might profitably make predictions according to how different sorts of offenders respond to various situations. Theories taking into account the interactions between persons and their environment may in future allow tolerably accurate predictions of future assaultive behavior under certain circumscribed conditions

Lick-shock contingencies in the rat

Hungry rats were allowed to lick an 8% sucrose solution and then one of four lick-shock contingency conditions was superimposed on the licking baseline. These conditions were: free-operant avoidance, free shock, punishment, and no shock. From highest to lowest response rates, the groups fell in the order—avoidance, no shock, free shock, and punishment. Lick rates adjusted rapidly to introduction and removal of the contingencies. Post-shock responding was lowest in the punishment condition and highest in the free shock condition. No method was found simultaneously to equate shock frequency and separate response rates for the three shock contingency conditions. Only small, or no, reductions in shock rate occurred over sessions under the free-operant avoidance schedule when the shock-shock interval was 10 sec but large reductions occurred when the shock-shock interval was reduced to either 1 or 2 sec

Testing the Cuckoldry Risk Hypothesis of Partner Sexual Coercion in Community and Forensic Samples

Evolutionary theory has informed the investigation of male sexual coercion but has seldom been applied to the analysis of sexual coercion within established couples. The cuckoldry risk hypothesis, that sexual coercion is a male tactic used to reduce the risk of extrapair paternity, was tested in two studies. In a community sample, indirect cues of infidelity predicted male propensity for sexual coaxing in the relationship, and direct cues predicted propensity for sexual coercion. In the forensic sample, we found that most partner rapists experienced cuckoldry risk prior to committing their offence and experienced more types of cuckoldry risk events than non-sexual partner assaulters. These findings suggest that cuckoldry risk influences male sexual coercion in established sexual relationships
