The caregiver-care receiver relationship (mutuality) in Parkinson's disease (PD) and its association with motor and non-motors symptoms, health-related quality of life (HRQoL), and caregiver burden have not fully been investigated. The aim of our study was to explore if (1) the level of mutuality perceived by PD-patients and PD-partners differs, (2) different factors are associated with perceiv...

How does one perceive groups of people? It is known that functionally interacting objects (e.g., a glass and a pitcher tilted as if pouring water into it) are perceptually grouped. Here, we showed that processing of multiple human bodies is also influenced by their relative positioning. In a series of categorization experiments, bodies facing each other (seemingly interacting) were recognized m...

This study purported to comparatively investigate the influence of collaborative writing on the quality of individual writing of four female Iranian and four female Malaysian students. The first semester students at a private university in Malaysia, who were comparable in terms of age, gender, study discipline, and language proficiency, were divided into two Iranian and two Malaysian dyads. The...

Dyads composed of unacquainted females (n=82) watched a cartoon while consuming salty aperitif snacks. The Affective Communication Test was used to measure nonverbal expressiveness. Computing intraclass correlation coefficients, the extent to which participants within dyads matched each other's food intake was analyzed. Food intake matched highly for dyads with two expressive individuals and mo...

Increased competition, globalization, and greater availability of communication technologies have lead to an increase in the number of geographically distributed teams. The distribution of these teams creates new contexts for team members that may make trust simultaneously more difficult and more important. In this chapter, we used data from 108 dyads on 12 globally distributed student project ...

Diploid yeast strains, homozygous for the mutation spo13, undergo a single-division meiosis and form dyads (two spores held together in one ascus). Dyad analysis of spo13/spo13 strains with centromere-linked markers on five different chromosomes and on a pair of human DNA YACs shows that: (a) in spo13 meiosis, chromosomes undergo mixed segregation, namely some chromosomes segregate reductionall...

The assessment of reliability and construct validity for scales used to evaluate families is potentially limited because standard coefficients are not computed appropriately using the combined responses for family members due to their possible intra-familial correlation. In this paper, we describe and demonstrate the use of linear mixed modeling to compute generalizations of such coefficients f...
