Although the validity of adult ADHD is well established and research has identified a variety of impairments associated with the condition in adults, study of how ADHD impacts an adult's ability to parent has been relatively neglected. Parenting is a particularly important domain of functioning given the familial nature of the disorder and emerging evidence that parenting behaviors play a role in the development or maintenance of child ADHD symptoms, comorbid psychopathologies, and other associated difficulties. In this paper, we focus on three broad categories of cognitive dysfunction proposed across models of ADHD - cognitive processes (e.g., working memory, planning, and inhibitory control), self-regulation deficits (e.g., self-monitoring of performance to detect errors or the need for regulation of behavior and/or emotions), and motivational or arousal difficulties (e.g., response to incentives, delay aversion). We consider how these deficits may lead to impairments in the parenting behaviors of effective behavioral control and emotional responsiveness, and review the available evidence regarding parenting in adults with ADHD symptoms. We conclude by noting the limitations in existing studies, and argue for further research that is theoretically grounded in how core deficits of ADHD may be related to dimensions of parenting. The implications of an improved understanding of how ADHD impacts parenting for the development of early intervention or prevention programs are outlined.

Problems of the form a + b -b have been used to assess conceptual understanding of the relationship between addition and subtraction. No study has investigated the same relationship between multiplication and division on problems of the form d x e ÷ e. In both types of inversion problems, no calculation is required if the inverse relationship between the operations is understood. Adult participants solved addition/subtraction and multiplication/division inversion (e.g., 9 x 22 ÷ 22) and standard (e.g., 2 + 27 -28) problems. Participants started to use the inversion strategy earlier and more frequently on addition/subtraction problems. Participants took longer to solve both types of multiplication/division problems. Overall, conceptual understanding of the relationship between multiplication and division was not as strong as that between addition and subtraction. One explanation for this difference in performance is that the operation of division is more weakly represented and understood than the other operations and that this weakness affects performance on problems of the form d x e ÷ e.
