Abstract

Dual-task interactions in posture and cognitive tasks have been explained as a competition for spatial processing structures or as interference in the online sensorimotor adjustments required for sensory integration. Going beyond these general terms accounts, we propose that interference between spatial and temporal operations in posture–cognition arises at least partly from the need to share a common behavioral context, such as a spatial frame of reference. Using immersive visualization and motion-tracking techniques, we manipulated the spatial reference frames for a standing task and a conjunction visual search task into or out of coincidence. Aside from performance trade-offs due to task-load manipulations, performing visual search in a non-coincident reference frame led to cognitive task and postural task performance decrements (Experiment 1). Postural dual-task decrements were also observed when visual search was split between coincident and non-coincident frames and both frame conditions rendered identical in visual information relevant to posture control (Experiment 2). We concluded that the postural control costs observed for posture–cognition dual-tasking may in part reflect costs of keeping tasks’ reference frames in register.

Indeed, recent work by Kunde and Hoffmann (2005) shows that the propensity to localize a search target with respect to a given reference frame increases as the uncertainty of its location with respect to that frame decreases. For displays with no relative motion between search items, as in the present study, any frame that stays attached to the stimulus set (i.e., a display-anchored, exocentric frame) is the least uncertainty reference frame.

Over time-scales shorter than 1 s, sway time series (such as COP) contain positive correlations indicating a tendency to carry on along the current direction of sway. At longer times-scales the time series contain negative correlations indicating a tendency to reverse direction of sway (Collins and Deluca 1994; Riley et al. 1998). The time-scale for the visual search task used in the present study was approximately 0.8 and 1.5 s, respectively, for the low and high load conditions.
