“…Within this view, higher COP entropy could indicate that they deployed a more efficient balancing. The efficiency with which postural balance (low COP variability and low attentional investment) is controlled is closely tied to the selection of an appropriate mode of spatial referencing (generally proprioceptive-based; Berthoz, 1991; Paillard, 1991; Kluzik et al, 2005; Streepey et al, 2007b; Isableu et al, 2010, 2011; Mergner, 2010; Slaboda et al, 2011a,b; Brady et al, 2012; Scotto Di Cesare et al, 2015). Several authors showed that these modes of spatial referencing are known to impact the attentional investment (Goodenough et al, 1987; Marendaz et al, 1988; Marendaz, 1989; Bailleux et al, 1990; Yan, 2010; Agathos et al, 2015).…”
