A social learning analysis of couples during the second postnatal month

Abstract

This study examined the marital satisfaction and behaviors of 32 couples at one and two months following the births of their first children. Self-report measures of daily satisfaction and daily spouse-observed behaviors were analyzed for patterns approximating those associated with distressed marital interaction identified through earlier social learning studies. Over the time period from 30 to 60 days postnatally, increases were found in spouses' tendency to reciprocate one another's behavior. Except for helpful behaviors involved with care of the infant, spouses at two months postnatally were more likely to reciprocate both irritating and rewarding behaviors than at one month. Nonsignificant decreases in marital satisfaction were accompanied by a mixed pattern of change for spouse-observed behaviors. Predicted changes over time in the proportions of pleasing and displeasing behaviors were evident in only half the comparisons. Increases over time were found for the predictability from spouse-reported daily behaviors to marital satisfaction, but an expected increase in the importance of negative behaviors to the multiple correlation with satisfaction was not obtained. Cross-lagged panel correlation analysis indicated that, for wives, increases in satisfaction at 30 days preceded a parallel increase in their reports of rewarding behaviors and a decrease in aversive behaviors from their husbands at 60 days postnatally. Implications of these findings for identification of couple risk factors for later clinical problems and for early family intervention are discussed.     

Let’s be healthy together: Relational motivation for physical health is more effective for women

Four studies examined the role of relationally-autonomous reasons in health behavior (RARHs) and how gender moderates their association with health outcomes. Study 1 (n = 160) involved the development of a measure of RARHs. The results of a factor analysis distinguished RARHs from other types of health reasons. In Study 2, participants (n = 284) completed a survey assessing their relational reasons prior to taking assessments of their body composition and fitness level. In Study 3, participants (n = 577) completed an online survey assessing RARHs, self-construal and health behaviors. The results of Studies 2 and 3 showed that RARHs positively predicted healthy outcomes for females only. In Study 4, participants (n = 72) were asked to complete an online survey, attend an orientation session, keep track of their exercise and nutrition over the course of a week, and attend a follow-up session. The results revealed that having an exercise partner was positively associated with RARHs, and that this in turn predicted reported effort and progress outcomes at the follow-up session for females only. Implications for theories of motivation and gender differences are discussed.     

Failure to replicate a QTL association between a DNA marker identified by EST00083 and IQ

In a paper published in this journal, a possible QTL association was reported between general cognitive ability and a marker, identified by an expressed sequence tag, EST00083 (Skuder et al., 1995). In two small samples, the frequency of the common allele of this DNA marker, which was shown to be in the threonine transfer RNA gene in mitochondrial DNA, was significantly greater in a high-IQ group than in a low-IQ group. As part of the ongoing IQ QTL Project (Plomin et al., 1995), we have attempted to replicate this QTL association. First, we found that the QTL association remained significant when we compared 51 high- and 51 -average IQ subjects, drawn in part from the samples used in the previous report. However, when we examined the association in new samples of 40 extremely high-IQ subjects and 50 average-IQ subjects, the association did not replicate. This underlies the need for replication in case-control studies of allelic association.     

PTSD and the influence of context: The self as a social mirror

The principal accepted models of posttraumatic stress disorder (PTSD) are based on both memory processing and biological/brain changes occurring when one's life or well-being is threatened. It is our thesis that these models would be greatly informed by community studies indicating that PTSD is predicted to a greater extent by earlier life experience and experiences that occur distant from the threatening event. These findings suggest posttraumatic responding is best conceptualized through the lens of the self-in-context, as opposed to imprinting that results from a given event at a given time. Moreover, studies of non-Western populations often do not express trauma as PTSD, or at least not primarily as PTSD, which argues against specific neural or memory encoding processes, but rather for a more plastic neural process that is shaped by experience and how the self develops in its cultural context, as a product of a broad array of experiences. We posit that fear and emotional conditioning as well as the ways traumas are encoded in memory are only partial explanatory mechanisms for trauma responding, and that issues of safety and harm, which are long term and developmental, are the common and principal underpinnings of the occurrence of posttraumatic distress, including PTSD.
