background: multiple sclerosis (ms) is an autoimmune,  neuro- inflammatory disease  of  central nervous system affecting physical, emotional, and cognitive aspects of patients. association of vitamin d deficiency and ms has been shown in previous studies. the aim of this study was to evaluate serum vitamin d level in ms cases and their sex-matched healthy siblings (who are genetically near simi...

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...

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 ...

Drawing on the social cognitive theory of self-regulation, we proposed a model considering an inverted U-shaped relationship between perceived overqualification and constructive voice. We reasoned from that this curvilinear effect would be moderated by leader consultation, which could intensify upward trend neutralize downward trend, mediated work engagement. conducted two studies to test our m...

PURPOSE/OBJECTIVES To develop and evaluate the feasibility of a brief intervention to attenuate the incidence of psychosexual morbidity within the dyad secondary to the diagnosis and treatment of breast cancer. DESIGN Quasiexperimental, including intervention and treatment-as-usual comparison groups. SETTING Breast clinic of a comprehensive cancer center in the Midwest United States. SAMP...

This study was focused on the role of gender-related differences in collaborative play, by examining properties of play as a complex system, and by using micro-genetic analysis techniques. A complex dynamic systems model of dyadic play was used to make predictions with regard to duration and number of contact-episodes during play of same-sex dyads, both on the micro- (i.e., per individual sessi...

The present experimental study investigates the impact of computer-supported collaboration and knowledge awareness regarding the source problems the collaboration partner has remembered on analogical problem solving. Collaborating dyads with an external representation for supporting knowledge awareness were compared to collaborating dyads without such an external representation and to a baselin...

Few studies have investigated patterns of emotion coregulation in families of children with Autism Spectrum Disorder (ASD) or contrasted the ways in which their emotion coregulation patterns differ from families of typically developing (TD) children. To address this gap, we used a dynamic systems approach to compare flexible structure and emotional content of coregulation between mothers and ch...
