Cognitive models of parenting give emphasis to the central role that parental cognitions may play in parental socialization goals. In particular, dual process models suggest that parental attribution styles affect the way parents interpret caregiving situations and enact behaviors, particularly within the realm of discipline. Although research has documented the negative behavioral repercussions of dysfunctional child-centered responsibility biases, there is heterogeneity in the level of these associations. Research has also demonstrated that parental working memory capacity may serve as an individual difference factor in influencing caregiving behaviors. Thus, our first aim was to document how maternal working memory capacity may moderate the association between mother’s dysfunctional child-oriented attributions and use of harsh discipline. In addition, from an ecological perspective, a second aim was to examine how socioeconomic risk may further potentiate the impact of maternal working memory. To accomplish these aims, a socioeconomically diverse sample of 185 mothers and their three-year old children were recruited to participate in a laboratory-based research assessment. Findings revealed that lower maternal working memory capacity may operate as a risk factor for attributional biases and harsh discipline, while higher working memory may serve as a protective factor in this relationship. Socioeconomic risk further moderated these findings. Results suggest that the moderating role of working memory may be particularly pronounced under conditions of socio-economic risk. The theoretical and clinical implications of these findings are discussed.

Guided by family risk and allostasis theoretical frameworks, the present study utilized a prospective longitudinal design to examine associations among family risk experiences, basal cortisol patterns, and cognitive functioning in children. The sample included 201 low-income children living within a mid-size city in the Northeastern United States. Children were assessed at ages 2, 3, and 4 years. Growth-mixture modeling (GMM) analyses revealed three basal cortisol patterns (elevated, moderate, low) and these remained relatively stable across time. Exposure to greater levels of family instability and maternal emotional unavailability predicted elevated and low cortisol patterns, which were associated with lower child cognitive functioning at age 4. Findings have implications for family risk processes that may underlie risk-related disparities in child cognitive outcomes.

Guided by the affective spillover hypothesis and the differential susceptibility to environmental influence frameworks, the present study examined how associations between interparental conflict and mothers’ parenting practices were moderated by serotonin transporter (5-HTT) and oxytocin receptor (OXTR) genes. A sample of 201 mothers and their two-year old child participated in a laboratory-based research assessment. Results supported differential susceptibility hypotheses within spillover frameworks. With respect to OXTR rs53576, mothers with the GG genotype showed greater differential maternal sensitivity across varying levels of interparental conflict. Mothers with one or two copies of the 5-HTTLPR S allele demonstrated differential susceptibility for both sensitive and harsh/punitive caregiving behaviors. Finally, analyses examined whether maternal depressive symptoms and emotional closeness to their child mediated the moderating effects. Findings suggest that maternal emotional closeness with their child indirectly linked OXTR with maternal sensitivity. The results highlight how molecular genetics may explain heterogeneity in spillover models with differential implications for specific parenting behaviors. Implications for clinicians and therapists working with maritally distressed parents are discussed.

Socioeconomic adversity has been targeted as a key upstream mechanism with robust pathogenic effects on maternal caregiving. Although research has demonstrated the negative repercussions of socioeconomic difficulties, little research has documented potential mechanisms underlying this association. Toward increasing understanding, the present study examined how maternal working memory capacity and inhibitory control may mediate associations between socioeconomic risk and change in maternal sensitivity across free-play and discipline caregiving contexts. This study used a longitudinal design, and utilized a socioeconomically diverse sample of 185 mothers and their 3.5-year-old toddlers. Multi-informants and methods were used to assess constructs. Findings revealed that maternal EF mediated associations between socioeconomic risk and parenting sensitivity with specific effects for working memory and baseline sensitivity and inhibitory control and change in sensitivity as childrearing demands increased. Results are interpreted within emerging conceptual frameworks regarding the role of parental neurocognitive functioning and caregiving. (PsycINFO Database Record

Background Harsh environments are known to predict deficits in children’s cognitive abilities. Life History Theory (LHT) approaches challenge this interpretation, proposing stressed children’s cognition becomes specialized to solve problems in fitness-enhancing ways. The goal of this study was to examine associations between early environmental harshness and children’s problem-solving outcomes across tasks varying in ecological relevance. In addition, we utilize an evolutionary model of temperament towards further specifying whether hawk temperament traits moderates these associations. Methods Two hundred and one mother-child dyads participated in a prospective multi-method study when children were 2 and 4 years old. At age 2, environmental harshness was assessed via maternal report of earned income and observations of maternal disengagement during a parent-child interaction task. Children’s hawk temperament traits were assessed from a series of unfamiliar episodes. At age 4, children’s reward-oriented and visual problem-solving were measured. Results Path analyses revealed early environmental harshness and children’s hawk temperament traits predicted worse visual problem-solving. Results showed a significant two-way interaction between children’s hawk temperament traits and environmental harshness on reward-oriented problem-solving. Simple slope analyses revealed the effect of environmental harshness on reward-oriented problem-solving was specific to children with higher levels of hawk traits. Conclusions Results suggest early experiences of environmental harshness and child hawk temperament traits shape children’s trajectories of problem-solving in an environment-fitting manner.
