Successfully meeting a shared goal usually requires co-actors to adopt complementary roles. However, in many cases, who adopts what role is not explicitly predetermined, but instead emerges as a consequence of the differences in the individual abilities and constraints imposed upon each actor. Perhaps the most basic of roles are leader and follower. Here, we investigated the emergence of “leader-follower” dynamics in inter-personal coordination using a joint supra-postural task paradigm (Ramenzoni et al., 2011; Athreya et al., 2014). Pairs of actors were tasked with holding two objects in alignment (each actor manually controlled one of the objects) as they faced different demands for stance (stable vs. difficult) and control (which actor controlled the larger or smaller object). Our results indicate that when actors were in identical stances, neither led the inter-personal (between actors) coordination by any systematic fashion. Alternatively, when asymmetries in postural demands were introduced, the actor with the more difficult stance led the coordination (as determined using cross-recurrence quantification analysis). Moreover, changes in individual stance difficulty resulted in similar changes in the structure of both intra-personal (individual) and inter-personal (dyadic) coordination, suggesting a scale invariance of the task dynamics. Implications for the study of interpersonal coordination are discussed.
Este artigo objetiva discutir as políticas públicas e sociais de lazer, verificando se a temática é pesquisada na Pós-graduação em Lazer, Recreación e Tiempo libre na América Latina. A metodologia desta pesquisa qualitativa foi composta por investigação bibliográfica e realização de entrevistas com 25 voluntários vinculados a cinco mestrados desenvolvidos em quatro países: Brasil, Costa Rica, Equador e México. Todos os entrevistados salientaram a relevância da temática, mas, ela não vem sendo estudada na maioria dos mestrados investigados. Destaca-se a importância de aprofundar conhecimentos sobre o tema, reconhecendo o lazer como um campo relevante, mobilizador de intervenções estatais e integrante das agendas políticas governamentais. Assim, ampliar os estudos e pesquisas sobre as políticas públicas e sociais de lazer é um desafio que se coloca para as cinco propostas formativas estudadas.
