Maternal child-centered attributions and harsh discipline: the moderating role of maternal working memory across socioeconomic contexts

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 3-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, and 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 socioeconomic risk. The theoretical and clinical implications of these findings are discussed.
