Investigating the role of two types of understanding in relationship well-being: Understanding is more important than knowledge

Understanding is at the heart of intimate relationships. It is unclear, however, whether understanding-partners' subjective feeling that they understand each other-or knowledge-partners' accurate knowledge of each other-is more important for relationship well-being. The present article pits these two types of understanding against each other and investigates their effects on relationship well-being. In a prospective study among 199 newlywed couples, partners' self-reported and perceived understanding and their knowledge in different domains were assessed. Understanding was independent of knowledge. Self-reported and perceived understanding predicted relationship well-being but neither type of knowledge did. Thus, subjectively feeling that one understands and is understood by one's partner appears to be more important to relationship well-being than actually knowing and being known by one's partner. © 2009 by the Society for Personality and Social Psychology, Inc

Facebook intensity, social network support, stability and satisfaction in long-distance and geographically-close romantic relationships:A test of a mediation model

The impetus for this study is the proposition that social network sites (SNSs), like Facebook, can be beneficial for romantic relationships via network support functions. This study investigated a model which proposes that the use of Facebook predicts relationship support from Facebook connections, and this, in turn, predicts relationship stability and satisfaction in romantic relationships. This mediation model was tested on data gathered via an online survey among individuals who use Facebook, who are in long-distance (LDRR, n = 142) and geographically-close romantic relationships (GCRR, n = 314). GCRR participants reported higher levels of Facebook intensity and relationship support, as well as perceived relationship stability and satisfaction than participants in LDRR. Moreover, the results indicated that Facebook intensity predicted higher access to Facebook relationship support in LDRR and GCRR which, in turn, predicted perceived relationship stability and satisfaction in LDRR; and only perceived relationship satisfaction in GCRR. However, Facebook intensity had direct negative impacts on relationship satisfaction in GCRR, and on perceived relationship stability in LDRR. Facebook intensity and Facebook relationship support were not associated with relationship stability in GCRR. This demonstrates the relative importance of SNSs, such as Facebook, in relationship stability for those in LDRR

Perceiving concealment in relationships between parents and adolescents: links with parental behavior

Item does not contain fulltextAlthough concealment in relationships is commonplace, little is known about its implications for the target of concealment. Two large-scale studies among adolescents and their parents tested the central hypothesis that parents' perception of child concealment predicts poorer parenting behaviors toward their child. Further, we investigated whether actual child concealment adds to the prediction of parenting behaviors through an interaction with parental perception of concealment. Study 1 yielded evidence for the hypothesized link, which was independent of actual concealment. Study 2 largely replicated these results for perceptions of both concealment and lying while controlling for perceptions of disclosure. Overall, these results suggest that parents' perception of child concealment coincides with poorer parenting behaviors, regardless of actual child concealment.20 p

Modeling of curved cantilever dielectric elastomer actuator using universal solution in finite bending

This study presents a model of a curved cantilever dielectric elastomer actuator (DEA) containing liquid-phase metal electrodes utilizing universal solutions from finite nonlinear elasticity. The DEA comprises a compliant capacitor which has been prestrained some prescribed amount, affixed to a substrate, and bonded to a secondary layer of unstrained bulk elastomer. Upon release of the cured layers, internal stresses cause a bending moment and force the final configuration into a beam with some initial curvature. Application of a voltage across the electrodes creates an electrostatic pressure, inducing compressive Maxwell stresses across the dielectric layer. This relieves some of the internal moment and forces actuation of the device in the form of beam straightening. We assume incompressibility and isotropic, neo-Hookean behavior of our bulk elastomeric material. Employing simplifying assumptions such as constant curvature across the length of the beam (i.e., a perfectly circular arc) and plane strain in the plane of actuation, we utilize the Universal Solution in finite bending to represent the kinematics and implement Maxwell’s equations to describe beam deflection as a function of applied voltage. We use the principal of minimum potential energy to solve for beam deflection (represented by curvature of the device) as a function of electric potential across the electrodes after considering energy contributions due to elasticity, electrostatics and expended electric work. This model is then compared to experimental data obtained from testing multiple fabricated devices. The emerging fields of soft robotics and wearable computing require new classes of soft and elastically deformable electronics, which unlike traditional electronic components, must be flexible and/or stretchable. Thus it is important to develop predictive and comprehensive models describing their behavior

Brief Report: Examining the Link Between Autistic Traits and Compulsive Internet Use in a Non-Clinical Sample

Individuals with autism spectrum disorders or autistic traits may profit from Internet and computer-mediated interactions, but there is concern about their Internet use becoming compulsive. This study investigated the link between autistic traits and Internet use in a 2-wave longitudinal study with a non-clinical community sample (n = 390). As compared to people with less autistic traits, people with more autistic traits did not report a higher frequency of Internet use, but they were more prone to compulsive Internet use. For women, more autistic traits predicted an increase in compulsive Internet use over time. These results suggest that, despite its appeal for people with autistic traits, the Internet carries the risk of compulsive use

A LINGUAGEM DO CORPO EM MOVIMENTO

O corpo foi visto de várias maneiras no decorrer da história até o momento em que estepassa a ser considerado objeto de estudos, iniciando-se assim o estudo da psicomotricidade.A psicomotricidade é a ciência que estuda os movimentos humanos, relacionando-oscom aspectos afetivos, motores e cognitivos. A utilização dessa ciência em sala de aulacontribui muito no processo de ensino e aprendizagem das crianças, o uso de atividadesque estimulem a coordenação motora ampla, a coordenação motora fina, a lateralidade, odesenvolvimento de percepção musical e o desenvolvimento da percepção corporal vêm acolaborar no desenvolvimento dos aspectos motores e cognitivos das crianças. O movimentodo corpo é de extrema importância para o desenvolvimento do ser humano, pois é a primeiraforma que o bebê encontra de comunicar-se com o mundo e é neste sentido que se faznecessário o estímulo desta prática tendo como auxílio o uso das linguagens do movimento,em especial a dança e os jogos simbólicos, que por sua vez contribuem no desenvolvimentoda linguagem corporal
