“…However, further increments in the cognitive demands of the secondary task will eventually result in attentional resource competition, thereby hampering the regulation of postural sway. In other words, and in line with previous suggestions [11,51,68,69], we predict a U-shaped relation between the cognitive demands of the secondary task and postural control. We further assume that the extent of this relation may be modulated by individual differences in attentional capacity.…”

“…Rather, this study supports the proposition of a U-shaped relation between cognitive processing demands and postural control [11,51,68,69] by providing direct empirical support on the basis of an experiment with monotonically increased levels of cognitive demands and individual differences in attentional capacity. Furthermore, the contrast between young and old adults confirms that individual differences in attentional capacity modulate the point at which a given level of cognitive demands change from being beneficial or detrimental for postural control.…”

“…Some research suggests that dual-tasking postural control compromises balance performance [2,7,32,36,39,40,43,59,60,68], as the resource view would predict. For instance, in support of the attention resource competition view, Andersson et al [2] found that performing a concurrent visuospatial search task decreased balance performance in middle-aged adults (M age = 40.4 years) under a challenging condition with attenuated proprioceptive sensory inputs (i.e., standing on a sway-referenced platforms).…”

“…In this regard, a number of researchers have postulated that the relationship between postural control and cognitive demand in dual-task situations could be U-shaped (e.g., [11,51,68,69]). According to this view, postural control performance is either improved or attenuated depending on whether the cognitive demand of the secondary task is low or high, respectively.…”

“…A review of the literature suggests that the interactions between mental processes and postural control can be modulated by factors such as stimulus and response modalities (e.g., [10,61,62,80]), difficulty of the concurrent secondary task (see [72], for review), postural constraints affecting the difficulty of the postural task (e.g., [9,19,50,68,79], individual differences in sensorimotor expertise (e.g., [68]), and aging (e.g., [11,14,22,25,28,32,36,63]). A number of studies considered the influence of experimental procedural factors of the concurrent task (e.g., stimulus presentation and response modes) on posture control.…”

Postural control in everyday life is generally accompanied by posture-unrelated cognitive activity. Thus, mild forms of dual-tasking postural control are the norm rather than the exception. Based on this consideration and available evidence, we propose and empirically examined, in young and old adults, a non-monotonic, U-shaped relation between the efficacy of postural control and concurrent cognitive demands that reflect opposing trends of the effects of attention focus and attentional resource competition. When instructed to perform an easy cognitive task that presumably shifted the focus of attention away from posture control, the center of body pressure (COP) excursions decreased both in young and older adults relative to a single-task baseline where the focus of attention was explicitly directed towards the postural control task itself. However, when performing more demanding cognitive tasks, older adults showed increased COP displacements, in line with the predicted Ushape function, whereas young adults did not. We outline mechanisms linking postural control to cognitive demand and suggest routes for future investigation.

Imagery plays an important role in hypnotic phenomena. Recent fi ndings have shown, however, that hypnotized subjects with high (Highs) and low (Lows) susceptibility to hypnosis undergoing guided imagery tasks centred on specifi c sensory modalities share similar visual imagery ability, but Highs obtain better imagery than Lows when tactile instructions are given. The aim of this experiment was to confi rm this fi nding using instructions of globally reduced perception instead of suggestions centred on specifi c sensory modalities, assuming that the preferred imagery modality would be the least easily suppressed. Changes in body sway (that are sensitive to cognitive activity because postural control requires attention) were used as indices of possible differences in the cognitive task load in Highs and Lows. The results confi rmed the hypothesis that Highs and Lows differ in their preferred imagery modalities, and showed that Highs' body sway was not modifi ed by the simultaneous imagery of globally reduced perception, while Lows increased their sway while perceiving the decreased sensory availability. The Discussion focuses on the similar networks involved in imagery and perception and on possible differences between Highs and Lows in the mechanisms of imagery/perception and sensory-motor integration.

This study was undertaken to investigate the reciprocity effect between postural and suprapostural performances and its underlying neural mechanisms wherein subjects executed a perceptual-motor suprapostural task and maintained steady upright postures. Fourteen healthy individuals conducted force-matching maneuvers (static vs. dynamic) under two stance conditions (bipedal stance vs. unipedal stance); meanwhile, force-matching error, center of pressure dynamics, event-related potentials (ERPs), and the movement-related potential (MRP) were monitored. The behavioral results showed that force-matching error and postural sway were differently modulated by variations in stance pattern and force-matching version. Increase in postural challenge undermined the precision of static force-matching but facilitated a dynamic force-matching task. Both static and dynamic force-matching tasks improved postural control of unipedal stance but not of bipedal stance, in reference to the control conditions. ERP results revealed a stance-dependent N1 response, which was greater around the parietal cortex in the unipedal stance conditions. Instead, P2 was modulated by the effect of the suprapostural motor task, with a smaller P2 in the right parietal cortex for dynamic force-matching. Spatiotemporal evolution of the MRP commenced at the left frontal-central area and spread bilaterally over the frontal-central and parietal cortex. MRP onset was subject to an analogous interaction effect on force-matching performance. Our findings suggest postural prioritization and a structural alternation effect of stance pattern on postural performance, relevant to implicit expansion and selective allocation of central resources for relative task-loads of a postural-suprapostural task.
