“…However, further research is needed to directly measure the direction of the attentional focus, for example by using eye tracking during bimanual coordination tasks. As previously revealed for unimanual sine wave tracking tasks (Masumoto & Inui, 2010;Voelcker-Rehage & Alberts, 2005), also for relative force and relative timing the maxima were performed with higher accuracy and lower variability than the minima.…”

“…Third, we expected force produced at the minima would be more variable and less accurate than performance at the maxima (cf. Masumoto & Inui, 2010), in particular for older adults (Voelcker-Rehage & Alberts, 2005). Fourth, with regard to practice, we expected the acquisition rate would be similar for all age groups (cf.…”

“…Force control has scarcely been investigated in bimanual tasks. Research on unimanual force control with periodic sine wave tracking tasks demonstrated higher variability of force (Voelcker-Rehage & Alberts, 2005) and timing (Masumoto & Inui, 2010) for peak forces (i.e., maxima and minima). Likewise, the authors demonstrated a higher bimanual coupling for the force minima than for the maxima in a bimanual force control task, where participants were asked to perform cyclic force modulations matched with a metronome (Masumoto & Inui, 2012).…”

“…Force and timing were assessed for the thumbs of each hand relative to the target line for each hand (hand-stimulus coupling) and in relation of both hands (hand-hand coupling). We focused on the peaks of the sine wave (for a unimanual task, see Masumoto & Inui, 2010) as representative characteristics of the sinusoidal performance. First, we expected performance would be generally lower with increasing age; we particularly assumed relative timing and relative force to be less accurate and more variable with increasing age .…”

The authors examined age-related differences in fine motor control during a bimanual coordination task. The task required the modulation of fingertip forces in the precision grip according to a visually presented sinusoidal antiphase pattern (force range 2-12 N; frequency 0.2 Hz). Thirty-four right-handed participants of three age groups (young, early middle-aged, and late middle-aged) practiced 30 trials of the task. Accuracy and variability of relative timing and relative forces at minima and maxima of the sine wave were analyzed for hand-hand and hand-stimulus couplings and compared between age groups. Analysis showed for relative timing and force weaker hand-hand than hand-stimulus coupling as well as lower accuracy and higher variability for minima as compared to maxima. Further, we analyzed practice effects by comparing the first and last trials and characterized the course of practice by detecting the transition of a steeper to a shallower acquisition slope for the different age groups. Late middle-aged participants demonstrated poorer performance than both other groups for all parameters. All groups improved performance to a similar amount. However, an age-related difference in acquisition strategy is visible. Late middle-aged participants seemed to have focused on improvement of force amplitude, whereas young and early middle-aged focused on timing.

“…There are data on the control of force production in intrapersonal unimanual (Masumoto and Inui 2010) and bimanual actions Inui 2012, 2013a;Ranganathan and Newell 2008) and in an interpersonal (joint) unimanual action (Bosga and Meulenbroek 2007;Inui 2013b, 2014b). However, to study the hierarchical organization of the motor control system in intra-and interpersonal actions, it is necessary to obtain data on force control in a joint bimanual action.…”
