Attachment insecurities and under-commitment in distressed couples: The role of positive and negative partner behaviors

Research has rarely considered intermediate variables in the association between attachment insecurities and relationship commitment. Based on attachment theory and Rusbult's Investment Model, we tested whether positive and negative partner behaviors explain this association in 91 distressed couples undergoing therapy. Path analyses based on the Actor–Partner Interdependence Model revealed that individuals with attachment avoidance reported perceiving fewer positive behaviors from their partner, which was associated with their own higher under-commitment. Partners of individuals with avoidance also reported perceiving fewer positive partner behaviors, which was in turn associated with their own higher under-commitment. Partners of individuals with attachment anxiety perceived more positive behaviors from their partner, which was associated to their own lower under-commitment. Perceived negative partner behaviors were only directly associated with higher under-commitment. These findings imply that perceived positive partner behaviors may be a key aspect to target in relationship therapy in couples who present with high attachment insecurities.     

SMALL PANELS OF EXPERTS IN DICHOTOMOUS CHOICE SITUATIONS*

This paper analyzes an expert resolution problem under an uncertain dichotomous choice situation. The experts share a common system of norms and therefore they all prefer the alternative that best suits their purpose. The selection of such an alternative is referred to as a correct choice. Our analysis of optimal decision rules for panels of independent experts is pursued for n-member decision-making bodies, n≤ 5. The suggested optimality criterion is the maximization of the probability of the panel's making the correct choice. Within our framework, this criterion is equivalent to the more common criterion of expected-utility maximization. For three-member panels of experts, the expert resolution problem is solved and illustrated by means of a medical application. For four-member panels, we list the three relevant decision rules, specify the conditions for all possible rankings of these rules, and, finally, present an extended consulting application. We conclude by listing seven relevant decision rules in the case of five-member decision-making bodies.     

Using video observation in the family context: The association between camera-related behaviors and parental sensitivity

Research on parental sensitivity often relies on video observation of parent–infant dyads. However, to date, no study has assessed both infants’ and parents’ interactions with the camera, and how this relates to parental sensitivity levels. This exploratory study micro-coded camera-related behaviors (CRB) by 4-month olds and their mothers and fathers on a 1-s time base, and examined the associations between those behaviors and parental sensitivity in 75 Dutch families. While parents’ CRB made up only 0.8% of total interaction time, infants’ made up 12%. Multi-level time-series analyses showed that infants’ CRB predicted mothers’. Infants’ CRB predicted fathers’ CRB, and vice versa. Maternal sensitivity was significantly lower when children looked at the camera for over one-third of total interaction time (Cohen's d = 1.26). These findings indicate further research is required to better understand how video observation might threaten ecological validity.
