Does Inequity Aversion Motivate Punishment? Cleaner Fish as a Model System

In human social interactions, punishment is often directed at cheating individuals. Subjective reports and neuro-imaging studies indicate that the experience of interacting with a cheat produces negative emotions and that the act of punishing a cheat assuages these feelings. However, while negative emotions may elicit punishment, the precise source of these emotions remains obscure. Specifically, it is often very difficult to tease apart whether punishing individuals are inequity averse (upset because cheating partner receives more than they should) or, more simply, whether they might be loss averse (upset because their payoffs did not meet their expectations). We compare results on punishment and inequity aversion in humans with results from a non-human model system, the cleaning mutualism between bluestreak cleaner wrasse (Labroides dimidiatus) and its reef-fish ??clients??. Male cleaner fish are known to punish females that cheat during joint client inspections, but a recent study failed to demonstrate evidence for inequity aversion in this species. We suggest that punishment in cleaner fish may be motivated by loss aversion rather than inequity aversion. Punishment in humans might also often be motivated by loss aversion??and empirical studies that disentangle the two competing motives for punishment are a clear research priority.     

CIA assets and the rise of the Guadalajara connection

Why do some drug traffickers prosper and grow powerful while others languish behind bars? The answer usually depends less on their ruthlessness than their political protection. That principle holds true on the international level no less than on the domestic level. Since World War II, one of the most critical sources of such institutional protection for the drug trade has been the U.S. Central Intelligence Agency. An ideal illustration of this phenomenon was rise of the Guadalajara Cartel in Mexico, one of the largest drug suppliers to the North American market in the late 1970s and 1980s. Its extraordinary success is explained by its connections first to the Mexican intelligence agency DFS and, through it, to the CIA.     

Psychological abuse of women: Six distinct clusters

This study was designed to identify patterns of psychological abuse (abuse) and determine whether different patterns mediate the effects of violence and sexual aggression. Interviews were completed with 578 (80.3%) of 720 women who volunteered for a study of “bad” or “stressful” heterosexual relationships. Cluster analysis with 51 items assessing many types of subtle and overt psychological abuse identified six groups. Cluster 1 sustained the most serious abuse, violence, and sexual aggression, but partners did not denigrate women or control finances. Cluster 2 sustained serious abuse which was more subtle than the dominating-controlling abuse discussed by others and had moderate violence and sexual aggression scores. Cluster 3 scored relatively low on abuse but reported controlling types (e.g., isolation, enforced secrecy) and relatively little violence and sexual aggression. Cluster 4 sustained the least abuse, violence, and sexual aggression but the abuse was overt (e.g., criticism, several types of control). Clusters 5 and 6 were similar with high abuse and moderate violence and sexual aggression scores but they experienced very different types of abuse. Total psychological abuse, threats of violence, acts of violence, and sexual aggression scores made different contributions to women's health, help seeking, and relationship perceptions depending on the pattern of abuse they sustained. Results for each type of harmful act are discussed separately.     

THE COLLABORATIVE DIVORCE PROJECT: A Court-Based Intervention for Separating Parents with Young Children

The role the legal process of separation and divorce plays in affecting outcomes for young children and their families was examined in the Collaborative Divorce Project (CDP), an intervention designed to assist the parents of children six years old or younger as they begin the separation/divorce process (married and unmarried couples). Evaluation and outcome data were collected from 161 couples, their attorneys, teachers, and court records. In addition to positive evaluations from both parents, intervention families benefited through lower conflict, greater father involvement, and better outcomes for children than the control group. Attorneys and court records indicate that intervention families were more cooperative and were less likely to need custody evaluations and other costly services. The CDP illustrates how prevention programs can be located within the courts, can be systematically evaluated, and can aid in helping the legal system function optimally for families with young children.     

The Family of the Juvenile Delinquent

Juvenile delinquency has historically been responded to by “de-familization” of the young offender; that is, removal to a training school or other institutional setting. The trend over the past two decades toward deinstitutionalization has meant that delinquent youngsters, who are now remaining in the context of their own communities and families, have been “re-familized.” This poses a major challenge for the juvenile justice system and community, who are stuck with the family but are not sure what to do about it. Little objective and systematic information is available concerning families of delinquents, either as an aggregate group or in individual cases. It is hypothesized that the families are as heterogeneous as are delinquent youngsters, but the juvenile justice system tends to scapegoat families and assumes they are all necessarily dysfunctional. A 10-point continuum of family functioning is proposed. It is suggested that families of delinquent youngsters are found at various points on this continuum: from the extremely impaired or criminogenic family, through the family that has serious problems but has something to offer its youngster if it receives effective help with those problems, to the family of average functioning that can serve as a major rehabilitative resource for the youngster.
