Unpacking insanity defence standards: an experimental study of rationality and control tests in criminal law

The present study investigated the impact of different legal standards on mock juror decisions concerning whether a defendant was guilty or not guilty by reason of insanity. Undergraduate students (N = 477) read a simulated case summary involving a murder case and were asked to make an insanity determination. The cases differed in terms of the condition of the defendant (rationality deficit or control deficit) and the legal standard given to the jurors to make the determination (Model Penal Code, McNaughten or McNaughten plus a separate control determination). The effects of these variables on the insanity determination were investigated. Jurors also completed questionnaires measuring individualism and hierarchy attitudes and perceptions of facts in the case. Results indicate that under current insanity standards jurors do not distinguish between defendants with rationality deficits and defendants with control deficits regardless of whether the legal standard requires them to do so. Even defendants who lacked control were found guilty at equal rates under a legal standard excusing rationality deficits only and a legal standard excluding control and rationality deficits. This was improved by adding a control test as a partial defence, to be determined after a rationality determination. Implications for the insanity defence in the Criminal Justice System are discussed.

Evidence in promoting positive parenting through the Program-Guide to Develop Emotional Competences

This study aims at providing evidence of the effectiveness of the Program-Guide to Develop Emotional Competences in promoting positive parenting. Contextual, institutional, methodological and professional issues were taken into account to develop a social innovation experience to support parenting as a preventive measure to family conflicts. The study describes both the contents of the Program-Guide and the methodological and evaluation issues that trained professionals need to consider when delivering the Program-Guide to families in natural contexts. Information was gathered and analyzed from 259 parents with children of ages 1-18 who participated in 26 parent training groups. A pre- and post-test design showed that after finishing the sessions parents perceived themselves more competent as parents according to the five dimensions of parenting competences considered: (1) emotional self-regulation abilities; (2) self-esteem and assertiveness; (3) communication strategies; (4) strategies to solve conflicts and to negotiate; and (5) strategies to establish coherent norms, limits and consequences to promote positive discipline. The study presents a discussion on these results from evidence-based parenting programs, as well as some strengths and limitations of the study, together with some suggestions for further research.
