Human movement encodes information about internal states and goals. When these goals involve dyadic interactions, such as in language acquisition, the nature of the movement and proximity become representative, allowing parts of our internal states to manifest. We propose an approach called Visually Grounded Virtual Accelerometers (VGVA), to aid with ecologically-valid video analysis investigat...

In this longitudinal study, we examined the moderating role of personality in the relationship between communication behaviors and long-term dyadic adjustment. A sample of 82 couples completed the NEO Five-Factor Inventory and the Dyadic Adjustment Scale. These couples were also videotaped during a 15-minute problem-solving discussion. Approximately 2.5 years later, these couples completed agai...

This study examined the validity of the Nursing Child Assessment of Feeding Scale (NCAFS) during toddlerhood, using a longitudinal design to assess the scale's convergence with the Toddler Snack Scale (TSS) between 12 and 36 months, and comparing videotaped interactions of 116 mother-toddler dyads. Differences between TSS mutuality classifications were found for the NCAFS subscales at each age....

This investigation examines how support from adult children is affected by their parents’ involvement in grandchild care. Instead of focusing on dyadic interactions, we adopt a gendered extended family perspective to examine how financial and emotional support from children was influenced when their siblings received help with child care from their elder parents. The data were from a two-wave (...

OBJECTIVE This study examines a transactional and multirisk model for Infantile Anorexia (IA) and investigates the contributions of the parent, the child, and dyadic interactional variables related to this feeding disorder. METHOD The sample consisted of 371 mother-child pairs (children aged 6-36 months), of which 187 pairs of mothers and normally developing children (ND-group), and 184 mothe...

Intimate partner violence (IPV) is a major health and human rights problem globally. However, empirical findings on the predictors of IPV cross-culturally are highly inconsistent, and the theory of IPV is underdeveloped. We propose a new analytical framework based on cooperative game theory in which IPV is a function of the power relations of the dyadic relationship, not simply the actors invol...

It has been known for more than a century that interacting people can generally achieve more accurate decisions than single individuals. Here we show that interacting guppy fish (Poecilia reticulata) achieve a superior level of numerosity discrimination well beyond the average ability of the isolated individual fish. This enhancement of numerical acuity was observed in dyadic interactions when ...

Why are some technology-mediated interactions between pairs of individuals more successful than others in generating creative ideas? To seek the answers to this question, we study the generation of creative ideas from a dyadic perspective. We examine the attributes of dyadic ties that influence the generation of creative ideas, and how the strength of influence changes contingently on the usage...

Why some dyadic interactions are more likely than others to trigger hinder the generation of novel and useful ideas? To investigate this question, we examine the attributes of dyadic ties that influence the generation of creative ideas, and how the strength of influence changes contingently on the mix use of communication media. Our study extends previous research by examining the impacts of Si...

The dyadic lifting schemes, which generalize Sweldens lifting schemes, have been proposed for custom-design of dyadic and bi-orthogonal wavelets and their duals. Starting with dyadic wavelets and exploiting the control provided in the form of free parameters, one can custom-design dyadic as well as bi-orthogonal wavelets adapted to a particular application. To validate the usefulness of the sch...
