The proof of the pudding: an illustration of the relative strengths of null hypothesis, meta-analysis, and Bayesian analysis

Some methodologists have recently suggested that scientific psychology's over-reliance on null hypothesis significance testing (NHST) impedes the progress of the discipline. In response, a number of defenders have maintained that NHST continues to play a vital role in psychological research. Both sides of the argument to date have been presented abstractly. The authors take a different approach to this issue by illustrating the use of NHST along with 2 possible alternatives (meta-analysis as a primary data analysis strategy and Bayesian approaches) in a series of 3 studies. Comparing and contrasting the approaches on actual data brings out the strengths and weaknesses of each approach. The exercise demonstrates that the approaches are not mutually exclusive but instead can be used to complement one another.     

Good Advice

Advice is interesting because it is a relationship that is built upon two asymmetries. Advice concerns what the advisee ought to do. For that reason, considerations of autonomy suggest that the advisee has a greater claim on what matters in deliberation. However, the advisor is wiser than the advisee. That suggests that the advisor has a greater insight into what matters in deliberation. These are the asymmetry of autonomy and the asymmetry of wisdom. To account for both, I argue for informed subjectivism. Informed subjectivism is the view that the quality of advice is determined by the likelihood that the advisee would consistently prefer acting on the advice to not acting the advice. The theory captures the asymmetry of autonomy by making the quality of advice based on the advisee’s judgment. It captures the asymmetry of wisdom by making the relevant judgments of the advisee be ones that are informed by experience.     

Aggressive behavior among girls and boys during middle childhood: predictors and sequelae of trajectory group membership

Using longitudinal data spanning early elementary through middle school, aggression behavior trajectory groups were identified for boys and girls. Early elementary school predictors of trajectory group membership were examined as well as whether trajectory group predicted physical aggression, covert delinquency, and substance use in 9th grade. Semiparametric group modeling identified aggression behavior trajectory groups. We identified four aggression trajectory groups for both genders described as “not involved,” “low,” “moderate,” and “high.” Attention problems, family conflict, and low school commitment and attachment were predictors of membership in higher aggression groups for both boys and girls. Low family involvement and low parental education predicted membership in higher aggression groups for boys; while depression, low‐income status, and having a single parent predicted higher aggression group membership for girls. For both boys and girls, few risk predictors distinguished between the moderate and high aggression trajectories except that low school commitment and having a teen mother were significant predictors of being in the high group for girls, and low parental education and income were significant predictors of being in the high group for boys. Membership in the higher aggression trajectory groups predicted involvement in violent behaviors, covert delinquency, and substance use in 9th grade. Findings suggest that children who display an early trajectory of high levels of aggressive behavior are more likely to continue involvement in later problem behaviors. Second‐grade predictors suggest commonality of risk across genders and provide evidence of modifiable targets for preventive interventions. Aggr. Behav. 32:1–15. 2006. © 2006 Wiley‐Liss, Inc.     

Primordial Moral Awareness: Levinas,Conscience, and the Unavoidable Call to Responsibility

The phenomenon of conscience as articulated in Roman Catholic moral theology has at least three dimensions: a fundamental and universal call to moral goodness; the search for moral truth; and a commitment to act in a particular way. Recent moral theology has tended to focus on the latter two dimensions, but there has been a strong call from Thomas Ryan for attention to the first dimension of conscience, especially its constitution in ‘horizontal relationality’. In this article I respond to Ryan's call, and demonstrate that the philosophy of Emmanuel Levinas can show how the experience of conscience is constituted in horizontal relationality, as well as that it supports an understanding of conscience as a universal call to responsibility. Correlatively, and perhaps more significantly, the introduction of Levinas’ philosophy into the discussion of conscience sheds light on a significant aspect of this call to moral responsibility. This highlights that the Roman Catholic understanding of conscience has ethical consequences for theology more broadly considered (as well as the other academic disciplines) in terms of understanding why it is impossible to set aside considerations of responsibility in the search for truth.
