We examined how mother–child emotional reminiscing is affected by culture, gender, and the valence of the event. Thirty-one Euro-American and 30 Chinese middle-class mothers and their 3-year-old children discussed 1 highly positive and 1 highly negative experience. Mothers and children in both cultures used a greater variety of negative emotion words than positive emotion words and were more li...

We used multilevel modeling to examine dynamic changes in respiratory sinus arrhythmia (RSA) and observer-coded interactive synchrony for mother-child dyads engaged in a laboratory interaction, to characterize parenting-at-risk. Seventy-nine preschooler-mother dyads including a subset with documented child maltreatment (CM; n=43) were observed completing a joint puzzle task while physiological ...

Ninety-two clinic-referred and nonclinical mother-child dyads in Spain and the USA were observed in their home settings under naturalistic conditions for a total of 477 hours. Children in the clinic-referred dyads were considered troubled because of conduct problems. The observations were aimed at assessing two forms of mother-child asynchrony, either of which was expected to differentiate clin...

Prosodic synchrony has been reported to be an important aspect of conversational dyads. In this paper, synchrony in four different dyads is examined. A Time Aligned Moving Average (TAMA) procedure is used to temporally align the prosodic measurements for the detection of synchrony in the dyads. An overlapping windowed correlation procedure is used to measure synchrony for six different prosodic...

In this paper we present an hierarchical approach to place categorization. Low level sensory data is processed into more abstract concept, named properties of space. The framework allows for fusing information from heterogeneous sensory modalities and a range of derivatives of their data. Place categories are defined based on the properties that decouples them from the low level sensory data. T...

This paper discusses aBlox a specification notation that we defined for automated synthesis of mixed-signal systems. aBlox addresses two important aspects of mixed-signal system specification: (1) description of functionality and performance issues and (2) expression of analog-digital interactions. The semantics of aBlox embeds concepts and rules of a computational model that we developed for m...

Temporal patterns of verbal and non-verbal behavior in human interactions reveal our attitudes toward each other and can have an outsized impact on outcome of activities such as negotiations, coordination and team work. However, not much work has been done towards automatically analyzing the temporal aspects of such behavior during collaborative tasks. In this paper, we take an initial step tow...

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....

The purposes of this article are: (a) to describe and analyze the accrual and retention patterns in a longitudinal randomized clinical trial with prostate cancer patients and their partners, and (b) to discuss strategies that were used to overcome challenges in conducting this family-based study. Initially, 429 dyads were referred to the study. Of these, 166 were not enrolled due to refusal (n ...
