The Legacy of a Grandparent's Divorce: Consequences for Ties Between Grandparents and Grandchildren

This study assesses the implications of divorce in the grandparent generation for grandparent‐grandchild relationships. The sample of 538 grandparents comes from the Iowa Youth and Families Project. Results indicate that many aspects of grandparenting are negatively associated with ever experiencing a divorce. Some of the negative effects of divorce are explained by ever‐divorced grandparents' greater geographic distance from, and weaker bonds to, their adult children. Negative effects of divorce are stronger for grandfathers and paternal grandparents. Furthermore, a good grandparent‐parent relationship can compensate for the negative effects of a grandparent's divorce on relations with grandchildren. Implications of these findings are discussed in the context of the increasing percentage of individuals moving into the later years who have experienced a divorce.     

IMPROVING THE NUMERICAL TECHNIQUE FOR COMPUTING THE ACCUMULATED DISTRIBUTION OF A QUADRATIC FORM IN NORMAL VARIABLES

This paper is concerned with the technique of numerically evaluating the cumulative distribution function of a quadratic form in normal variables. The efficiency of two new truncation bounds and all existing truncation bounds are investigated. We also find that the suggestion in the literature for further splitting truncation errors might reduce computational efficiency, and the optimum splitting rate could be different in different situations. A practical solution is provided. The paper also discusses a modified secant algorithm for finding the critical value of the distribution at any given significance level.     

Personal Identity and Civic Responsibility: "Rising to the Occasion" Narratives and Generativity in Community Action Student Interns

Twenty–two students in a community action certificate program supplied "rising to the occasion" narratives during summer–long internships. They also filled out measures of generativity. Twenty–one students in an international studies certificate program that also included a summer internship served as a comparison group. Both groups reported equal personal growth from rising to the occasion experiences and no differences on measures of optimism, self–esteem or generativity. However, the community action students linked their personal growth experiences to future community service; a regression analysis also revealed that the best predictor of their stress–related growth was their level of generative concern. No comparable links emerged for the comparison group. Implications for cultivating connections between personal identity and civic responsibility through service–learning are discussed.     

The Importance of the Coparental Relationship for Nonresident Fathers’ Ties to Children

We examine the importance of the coparental relationship for nonresident fathers’ ties to their children. Using data from Wave 2 of the National Survey of Families and Households, we focus on the link between two dimensions of coparenting, cooperative coparenting and conflict over childrearing, and three dimensions of nonresident father involvement, contact, relationship quality, and responsive fathering. Cooperative coparenting predicts more frequent father‐child contact, which in turn predicts higher relationship quality and more responsive fathering. Conflict over childrearing, however, is not significantly related to nonresident father involvement. Findings are consistent across different groups of children. Results suggest that cooperative coparenting between parents who live apart is associated with stronger ties between nonresident fathers and their children.     

When Children Have Two Mothers: Relationships With Nonresident Mothers,Stepmothers, and Fathers

Using data on 294 adolescents from the National Longitudinal Study of Adolescent Health who live with a biological father and have both a resident stepmother and a nonresident biological mother, this study examines the prevalence, antecedents, and consequences of adolescents’ closeness to each of their parents. Findings demonstrate that adolescents vary in their likelihood of having close relationships to resident fathers, resident stepmothers, and nonresident biological mothers, but when they can do so, they appear to benefit. Close relationships with both resident fathers and nonresident mothers are associated with fewer adolescent internalizing and externalizing problems. Closeness to resident stepmothers, however, is unrelated to these two outcomes. Results suggest that fathers play a particularly important role in these families.     

Infant Contingency/Extinction Performance After Observing Partial Reinforcement

Social information gathering by infants 6 and 12 months old was examined as a foundation for later social learning that may be uniquely human. Infant performance on a contingency/extinction task was studied following a caregiver demonstration of the contingency on varied reinforcement schedules. Infants who observed caregivers receive any reinforcing stimulation in pretraining decreased responding over their own acquisition period, possibly because they began to habituate to the reinforcer. In extinction, infants who observed caregivers receive partial reinforcement in pretraining were more persistent in responding than others. This suggested that direct experience with partial reinforcement is not needed for greater persistence in extinction. These studies revealed details of social learning in the 1st year.
