Sophisticated cognitive abilities have been documented in honeybees, possibly an aspect of their complex sociality. In vertebrates brain asymmetry enhances cognition and directional biases of brain function are a putative adaptation to social behaviour. Here we show that honeybees display a strong lateral preference to use their right antenna in social interactions. Dyads of bees tested using o...

BACKGROUND Intimate partner violence (IPV) and coercion have been associated with negative health outcomes, including increased HIV risk behaviors, among men who have sex with men (MSM). This is the first study to describe the prevalence and factors associated with experiencing IPV or coercion among US MSM dyads using the actor-partner interdependence model (APIM), an analytic framework to desc...

As part of long-term care reforms, home-care organisations in the Netherlands are required to strengthen the linkage between formal and informal caregivers of home-dwelling older adults. Information on the variety in mixed care networks may help home-care organisations to develop network type-dependent strategies to connect with informal caregivers. This study first explores how structural (siz...

During the past decade, researchers have commonly employed one of two sets of interstate dyads as the population of cases in quantitative analyses of international conflict, either “all dyads” or “politically relevant dyads.” The main argument against using the “all dyads” set is that includes many dyads where there is no chance of conflict, and so analysts using this set are examining many pai...

OBJECTIVE A new methodology is introduced to scale health states on an interval scale based on similarity responses. It could be well suited for valuation of health states on specific regions of the health continuum that are problematic when applying conventional valuation techniques. These regions are the top-end, bottom-end, and states around 'dead'. METHODS Three samples of approximately 5...

In this paper we present the results of an eye-tracking study on collaborative problem-solving dyads. Dyads remotely collaborated to learn from contrasting cases involving basic concepts about how the human brain processes visual information. In one condition, dyads saw the eye gazes of their partner on the screen; in a control group, they did not have access to this information. Results indica...

Learning to argue in a computer-mediated and structured fashion is investigated in this research. A study was conducted to compare dyads that were scripted in their computer-mediated collaboration with dyads that were not scripted. A process analysis of the chats of the dyads showed that the scripted experimental group used significantly more words, engaged in significantly more broadening and ...

We assessed the use of a joint activity schedule to increase peer engagement for preschoolers with autism. We taught 3 dyads of preschoolers with autism to follow joint activity schedules that cued both members of the pair to play a sequence of interactive games together. Results indicated that joint activity schedules increased peer engagement and the number of games completed for all dyads. S...

Abstract Backchannels (BCs; listener signals such as ‘mmhm’ or ‘okay’) are a ubiquitous and essential feature of spoken interaction. They used by listeners predominantly to support the ongoing turn their interlocutor signal understanding agreement. Listeners seem be highly sensitive exact realisations BCs judge deviations from typical forms negative. Very little is known about use speakers diag...
